I ask for an opinion to experts.
I installed the app Battery Life Repair
https://play.google.com/store/apps/details?id=com.BoshBashStudios.batterydoctorrepair
I can't understand if this app is really effective or if it is a fake. In both cases, if you want to give your opinion can you justify it with technical considerations?
It's strange to see so many high ratings, but it is also strange that there are no tests or in-depth reviews.
Sorry for bringing a thread from the dead but I am also very curious as to how this app works (or if it does at all).
Such apps don't work.. They're usually fake and earn money through ads. Battery life is purely hardware and can't be increased by a software other than changing kernel features...

what a load of crap.
You can increase the length of your battery time betweeen charges by lessening the load on the cpu(which causes ups in voltage usage).
we reduce cpu load by reducing ram usage too.
also, turning the display brightness down and turning off unneeded features like bluetooth or wifi.
the kernel can be made more efficient like you said. so i agree there.

Trying to do that the battery app takes more battery by being in the background always. sometimes it also steals data.. There's no point you're better of without it.

Of course the battery does nothing.
thats what the settings > battery
function is for anyways. to see the resource hog of the system.
so it works in identifiying the problem.
but your right, the battery app is unnecessary since we already have a stock implementation.
but that wasn't my point. my point is that you can modify the userspace for more battery between charges.

At the end of day we agree that battery apps are not required... Android is pretty optimized by itself.
Decrease screen brightness and timeout it takes the highest amount of battery.

"At the end of day we agree that battery apps are not required.." obviously.
"Android is pretty optimized by itself. " its not about android(I didnt mention android being optimized, I figured that it was pretty obvious and didnt need discussion), it was about android having the tools to find the problem. see the following:
"Decrease screen brightness and timeout it takes the highest amount of battery. "and this brings me to MY POINT.
We are talking about app hogs which ARE a problem.
I would expect the OP has enough of a brain to reduce the brightness.
You have app services that use tons of ram and cpu. Why can't you accept that?
The theory behind a battery app is legitimate, but the OP just has to use the builtin android application.

Confrontation Much
The original posting he said was that software does not have impact on hardware in that it can not fix physical damage on the battery such as dead cells.
Such apps are just fake.
I purchased a new phone and same day I installed repair battery life. It showed 8 low cells and one inactive. It claimed it will increase my battery life by 18% (WOW, LOL)
After that I tried again and it showed me all green cells.
I cleared the app's cache, cleared data and uninstalled the app.
Later on, I calibrated the battery with another app called "battery fix" which needs root and deletes batterystats.bin file
I once installed "repair battery life" and guess what? It showed again 8 low cells and one inactive.
It's just another fake crAPP
Number of cells shown suggests fake.
I tried Battery Life Repair by "Extended Apps " and I remain very sceptical. Nowhere it is explained what the app actually does.
A normal Phone has one or two cells. This app shows 100 cells and claims that some are broken or damaged and the software can repair it through some extraordinary (supernatural?) process. It Claims it repaired these problematic cells (like 5 out of 100), although it physically makes no sense considering a phone has one or two cells, which are usually either working or broken. Then it also requests access to media, identity and accounts, which is suspicious given what the app claims to do.
Comments in the app-store just prove to me that placebos work. On the other hand, some people figured that if the "battery repair" is done, the app data is deleted and the app run again, it again shows the same amount of "problematic cells".

I strongly suspected myself this app is complete bull twaddle, but I was also curious so installed it just to see what it makes of the battery "analysis".
It magically 'fixed' the problem cells, but unlike you on a subsequent retest the previously 'faulty cells' had still be 'fixed'.
I wonder how this app is polling the 'cells'? Or is it just making up some fancy graphics and not actually doing anything at all under the hood?
I also wonder what would happen if I switched batteries or took the existing one out and in again? Maybe I'll try at some point.
This is my experience.
I thought this is impossible but i installed it just to try..
In that time i first tryed it i had Galaxy 3 Apollo. Battery was so bad that percentage was going low when you were looking on it and after some short period of time phone just shutdown by itself.. I decided to try it so maybe i save money for new battery. With few shutdowns i finally did it and something happen. Battery didn't go low that way and phone stoped turning off by itself!! It could stop while i was washing dishes but it was "fixed" after i used that app, so i dont know. I don't personally think that some app can fix hardware issue but i think it works as some "refresh" or something like that. I don't know really but in my case was money saver what ever that is. Oh and i'm talking about "Extended Apps" app.. :/
I'm also skeptical about these things but unlike others in here, I tried before drawing conclusion with my awesome rational brain. And yes it works marvelous. My Galaxy Note 3 battery is working as brand new, giving 3 to 4 days without charging and it was 1 to 2 days before the app. I don't think that is placebo effect and I have absolutely no idea what the app does, and too bad the dev doesn't have a website, but the app is good. Also using the other app from the same dev, called Advanced Battery Calibrator and letting the phone charge till 100% while off did wonderful things.
I still wonder how it can fix hardware of it simply erase data from the battery increasing risk to catch on fire, but it does work.
As far as I know, the software keeps data of the battery in other to avoid charges over 100%. With time that will effectively make the battery charge till 99% then 98% and goes on, till u have a battery on 70% for example but the software say its 100%, because it wont charge more than that to avoid the risk of fire. Perhaps this app erase that data and increase the risk of mal function. But I have no idea.

ofc is not gona revive a battery,but even that it can be made,in some cases,i saw that of ppl proving that live,they took a dead battery and test it to show that it is dead and just used another same model battery that it was working and hold them connected like 5 min toghether,after that it just put the dead battery at charged and what u know?it did revived it,no idea how the battery actually work,but it seems that they can actually get stuck somehow and they can get a "forced" revive,like a CPR for humans,but like i said,not working with all,same as like on humans,not all can be revived with CPR,but i guess that this app has to do something coz like some in here i did used it and ... the magic worked,not on a dead battery,so scheptical as it sounds,on some batteries it works even tho maybe is not something hardware but maybe just something software,why i say that,i had a tablet and a few times when i was restarting the tablet,after a min was turning off coz of battery 0%,and that after i got the recharger plug off,so it was 100% for sure,after a few times restarting the tablet it was showing again 100 % as it should be,so i guess that not even android is always reading the data correctly
Of course is a full fake. Uninstall them, becouse they can do bitcoin mining or whatever gain trough pupup and promotions., as well as getting your data.
1) Ion litium or polymer batteries cannot be repaired.
2) cells are 1 or max 4 not 256 as those apps shows
3) clearing the cache brings different fault cells
4) reinastalling shows other broken cells
5) strangely the application after "repair" stays open in background. So at least the word "repair" is a joke fooling people.
6) dynamic ram and ddr are always powered and refresh cycles are required in all the address space generally, so saying that freeing ram allow more battery duration is a fake.
7) whatever the app does to have battery least more is just sw and tricky. I would not rely on that and remove the app.

Didnt notice this was my brothers account he uses my phone
Hello, there's a way to calibrate your battery without root.
to calibrate your battery, i found by my self a way to(when i did it, the battery time left was increased):
1)charge your phone to 100% battery.
2)turn on- wifi, auto rotation, bluetooth...(everything that is consuming battery not including apps)
3)leave your phone with screen off.
4)discharge much as you can.
5)when you finished, charge your phone and don't use the phone.
optional:
if you want a proof that this is worked- open settings and see how much time left for your battery(you will see that it had been increased).
FYI I just finished testing Battery Life Repair 2018 by running it on a new Android tablet with a huge 8000+mAh battery. It reported about 14 weak or bad cells out of a total of 120 cells. When told to fix those cells, it requests you to download another of their apps to help support them. Just say YES, then kick back out without downloading and the fix finishes. I had hardware "USB Safety Tester" connected during this test (it displays various info including the charging voltage and amperage). With about 12% of the cells reported bad, after the fix the Tester recorded zero increase in Volts or Amps. So it maintained a steady watt draw from the charger even after 14 more cells were now drawing watts to charge. Next I cleared storage on the app, ran it again, and got 12 different cells reported to have problems. Fixed those cells, and again, no change in charge draw.
I also found it strange that it would use WIFI and Cell Data and run in the background. Why?
The Battery Life Repair app reports that my Galaxy S5 also has 120 cells in its battery. Seeing as almost 99% of phones and tables have a SINGLE cell in their battery (one or two phones have 2 cells), the display of a 120 cell grid seems rather fishy. Having a 120 cell battery requires cell balancing hardware and software that that would add to the cost of the phone, plus make the battery physically larger. My electric bike has about 80-90 cells in it and it weighs about 15lbs and is 30,000 mAh and 47 volts. Hard to do in one or two cells. That is a good example of why a multi cell (3.6 v each?) battery is needed. But not a cell phone or tablet.
I know my test is not the most scientific, but at least I did check for a change in wattage draw before and after fixing cells, and not just ecstatically claim my battery has improved.
So I call Battery Repair Life 2018 to be a steaming pile of BS that is probably robbing you of your contacts and other personal information while running in the background sucking up your data plan. But, hey, that's just me.

I got an replacement due to my phone beyond repair.
I'm running original stock firmware, of-course rooted. Since the replacement I'm trying to get my phone to full charge but it doesn't and also I notice that the charging is quite slow.
I installed "Battery Monitor Widget" to see how much power it is drawing and found that AC power draws only about 350+mA and sometimes it is as low as 8mA. (Some times it draws about 750+mA). I notice that the temperature also reaches somewhere about 45 to 48 degree.
Once it reaches about 90% or so, it starts to drain battery instead of charing it.
I find it quite abnormal. Anyone with this kind of problem and found an solution?
Thanks in advance for the replies and suggestions.
What I'd sudjest is updating your phone through seus or PC companion or if your an American at & t user update to a newer firmware through the flash tool (you can find I link to it through my signiture) or if you can't update try and use the repair option through seus or PC compainion.

Thanks for your reply.
I did that yesterday. I repaired the firmware and reloaded all the application one by one from scratch. The only thing I restored is contacts so that I could eliminate all the other factors which can cause this issue.
My other suggestion would be to install xrecovery and wipe your battery stats I guess. You can find a link to xrecovery through the link in my sig

Good idea. I will try that as well as try to do a clean wipe and just try to charge with nothing loaded in. That will give a better idea where the problem is.
Thanks for the great tip, I will update you tomorrow.
Had that happen before, I had to remove sim card and let it drain out slowly for a week, then charge. Problem solved
I think I had similar problem, except that my processor went on full load when its almost fully charged causing it to drain the battery instead. Still lookin for answer to that, will wiping battery stats help?
I reset my phone to factory and did a re-flashing again using SEUS and I tried it charging immediately without loading any application (only loaded Battery Monitor Widget from Market to see the battery temperature and mA units drawn) and wow, it charged like a normal X10. So I guess it has something to do with whatever I loaded or modded it with.
I'm trying to find it out. Later tonight I will try to load all the application one-by-one and try again to charge to see whether I can isolate it.
During this process, I did takeout my SIM card for a period of 1 hour or so, so not sure whether that did the trick (If that's the case, thanks to gogogu)
In the meantime, I have a strong feeling it would be due to the flashtool and new recovery, but again there isn't any proof. I suspect this because this is the new thing I did compared to my old phone.
Any thoughts are welcome.

I don't have issues with processor. It works at full throttle when it supposed to work and then goes back to normal.
Hrmmm alright, but if you ever had the draining issue while charging and the battery temp rises up again. Check the CPU usage just incase
After yesterday's event, seems like stable (I did face the same issue once). Not sure which cured it and currently monitoring...
EDIT: Back to square one. The issue started again and the battery refues to fully charge! I'm going mad
Finally given up, sent for service and came back after 5 days of repair.
Repair Notes: No problem found !!!
But today morning I tried to charge and it's the same issue . Makes me go mad. Really, I don't know what to do!
Please help me friends .......
I too have exactly the same problem with my x10i.....
tried everything like rooting, using stock & custom ROMs, etc... still problem persist ...
while charging , power goes from 900mA to 200mA or lower, & doesn't reach 100% full...
i use current widget from market to read the power values ....
please help me friends .... to resolve my problem ...

I realize that much of this is common knowledge on XDA. Still, every day I see people post about how their phone "loses" 10% as soon as it comes off the charger. I also have friends who can't understand why their battery drains so quickly. Trying to explain this to people without hard numbers is often met with doubt, so I figured that I'd actually plot it out with real data.
So it's not a piece that is optimized for this audience, but I hope that you find it interesting.
--------------------------------------------------
Your Smartphone is Lying to You
(and it's not such a bad thing)
Climbing out of bed, about to start your day, you unplug your new smartphone from its wall charger and quickly check your email. You've left it plugged in overnight, and the battery gauge shows 100%. After a quick shower, you remember that you forgot to send your client a file last night. You pick up your phone again, but the battery gauge now reads 90%. A 10% drop in 10 minutes? The phone must be defective, right?
A common complaint about today's smartphones is their short battery life compared to older cell phones. Years ago, if you accidentally left your charger at home, your phone could still make it through a weeklong vacation with life to spare (I did it more than once). With the newest phones on the market, you might be lucky enough to make it through a weekend.
And why should we expect anything else? Phones used to have a very short list of features: make and receive phone calls. Today we use them for email, web surfing, GPS navigation, photos, video, games, and a host of other tasks. They used to sport tiny displays, while we now have giant touch screens with bright and vibrant colors. All of these features come at a cost: large energy requirements.
Interestingly enough, improvements in battery management technology have compounded the average user's perception of this problem. Older phones were rather inelegant in their charging behavior; usually filling the battery to capacity and then switching to a trickle current to maintain the highest charge possible. This offered the highest usage time in the short-term, but was damaging the battery over the course of ownership. As explained at Battery University, "The time at which the battery stays at [maximum charge] should be as short as possible. Prolonged high voltage promotes corrosion, especially at elevated temperatures."[1]
This is why many new phones will "lose" up to 10% within a few minutes of coming off the charger. The reality is that the battery was only at 100% capacity for a brief moment, after which the battery management system allowed it to slowly dip down to around 90%. Leaving the phone plugged in overnight does not make a difference: the phone only uses the wall current to maintain a partial charge state.
To monitor this, I installed CurrentWidget on my HTC ADR6300 (Droid Incredible), an app that can log how much electric current is being drawn from the battery or received from the charger. Setting it to record log entries every 10 seconds, I have collected a few days worth of data. While many variables are involved (phone hardware, ROM, kernel, etc) and no two devices will perform exactly the same, the trends that I will describe are becoming more common in new phones. This is not just isolated to a single platform or a single manufacturer.
Chart 1 shows system reported battery levels over the course of one night, with the phone plugged in to a charger. Notice that as the battery level approaches 100%, the charging current gradually decreases. After a full charge is reached, wall current is cut completely, with the phone switching back to the battery for all of its power. It isn't until about two hours later that you can see the phone starts receiving wall current again, and even then it is only in brief bursts.
The steep drop in reported battery seen past the 6.5 hour mark shows the phone being unplugged. While the current draw does increase at this point (since the phone is being used), it still cannot account for the reported 6% depletion in 3 minutes. It should also be obvious that maintaining a 100% charge state is impossible given the long spans in which the phone is only operating on battery power.
Using the data from CurrentWidget, however, it is quite easy to project the actual battery state. Starting with the assumption that the first battery percentage reading is accurate, each subsequent point is calculated based on mA draw and time. Chart 2 includes this projection.
Now we can see that the 6% drop after unplugging is simply the battery gauge catching up with reality.
The phone manufacturers essentially have three choices:
1. Use older charging styles which actually maintain a full battery, thereby decreasing its eventual life
2. Use new charging methods and have an accurate battery gauge
3. Use new charging methods and have the inaccurate battery gauge
Option one has clearly fallen out of favor as it prematurely wears devices. Option two, while being honest, would most likely be met with many complaints. After all, how many people want to see their phone draining down to 90% while it is still plugged in? Option three therefore offers an odd compromise. Maybe phone companies think that users will be less likely to worry about a quick drop off the charger than they will worry about a "defective" charger that doesn't keep their phone at 100% while plugged in.
Bump It. Or Should You?
One technique that has gained popularity in the user community is "bump charging." To bump charge a device, turn it off completely, and plug it into a charger. Wait until the indicator light shows a full charge (on the ADR6300, for example, the charging LED changes from amber to green) but do not yet turn the device back on. Instead, disconnect and immediately reconnect the power cord. The device will now accept more charge before saying it is full. This disconnect/reconnect process can be repeated multiple times, each time squeezing just a little bit more into the battery. Does it work?
The following chart plots battery depletion after the device has received a hefty bump charge (6 cycles) and then turned on to use battery power. Note that the system does not show the battery dropping from 100% until well over an hour of unplugged use, at which point it starts to steadily decline. Again, however, it should be obvious that the battery gauge is not syncing up with reality. How could the rate of depletion be increasing over the first 5 hours while the rate of current draw is relatively steady? And why does the projected battery line separate from the reported levels, but then exactly mirror the later rises and falls?
The answer, of course, is that bump charging definitely works. Rather than anchoring our projected values to the first data point of 100%, what happens if we anchor against a later point in the plot?
Aligning the data suggests that a heavy bump charge increases initial capacity by approximately 15%. Note that the only other time that the lines separate in this graph was once again when the phone was put on the charger and topped up to 100%. Just as with the first set of graphs, the phone kept reporting 100% until it was unplugged, dropped rapidly, and again caught up with our projections.
So what does it all mean?
If you absolutely need the highest capacity on a device like this, you will need to bump charge. There are currently people experimenting with "fixes" for this, but I have yet to see one that works. Be warned, however, that repeated bump charging will wear your battery faster and begin to reduce its capacity. If you are a "power user" who will buy a new battery a few months from now anyway, this presumably isn't a concern. If you are an average consumer who uses a device for a few years, I would recommend that you stay away from bump charging. The bottom line is that you don't really "need" to do it unless you are actually depleting your battery to 0% on a regular basis.
If you are someone who can top off your phone on a regular basis, do it. Plug it in when you're at home. Plug it in when you're at your desk. As explained by Battery University, "Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory."[2]
Beyond that, the best advice I can offer is to stop paying such close attention to your battery gauge and to just use your phone. Charge it whenever you can, and then stop obsessing over the exact numbers. If you really need more usage time, buy an extended-capacity battery and use it normally.

hi
is it required to battery caliberate after flashing new rom?
and when ever i reboot my system either battery jumps from 10% to 30 or more
or becomes less than 10%..
if i should then which app should i use?
any guidnace
plz
TY
No such thing. After you flash a new rom, charge the phone to 100%, turn it off, remove the battery for 30 seconds, replace the battery, turn phone on, enjoy.
Anyone selling you the whole calibration thing is selling you voodoo.
hi
thanks for your reply
plz suggest me best battery app with battery saving feature , suggestion on what we can do with remaining battery , expected full time charge , complete graph or battery usage history by apps?
paid or free , tell me best one
thank you
There's lots of battery apps on Google Play, there's no such thing as the best one, go have a look under the Tools section in Apps (you'll also find some under productivity). Stay away from apps like Juice Defender that claim to save you battery by doing things automatically which you can do yourself in two seconds, these have been proven time & again on XDA to use more juice than they save.
ivl try battery monitor
thank you
No probs ;-)

No such thing. After you flash a new rom, charge the phone to 100%, turn it off, remove the battery for 30 seconds, replace the battery, turn phone on, enjoy.
Anyone selling you the whole calibration thing is selling you voodoo.

Wouldn't that procedure above be considered calibrating the battery? LOL. J/K. Couldn't resist .

actually it cannot. this way you only help the system in your phone recognize full capacity of battery (which is not even full because not one battery works at it's full capacity - but it's fullest you will get at this point of your battery life). when it's about calibrating - listen to MistahBungle - it's all voodoo. you cannot calibrate li-ion battery unless you kill it and then revive. by killing it I don't mean depleting it in your phone, because even when phone shows the battery is fully depleted it's really not - there is still some juice in it. you'd have to use e.g. special charger which can drawn juice out of battery and make it really empty. only then your battery is dead and useless. you may revive it by applying cca. 5V but actually it not always works. so you cannot calibrate your battery in home environment.
what you can do is "re-calibrating" so called fuel gauge (description under links given below) and you may also help your system recognize the real state of your battery charge. sometimes it happens that systems readings are wrong and battery is on 85% but system is reading it as 50 or 100%. to help it read battery chip correctly you do the thing MistahBungle so helpfully described. sometimes you even don't have to do it but wait 2-3 charging cycles and system will adjust it's reading itself. by charging cycles I mean charging like from 20-100%. why not from 0%? because even if it's not a real depletion state, li-ion batteries doesn't like the state of being discharged too much.

and is there any way to stop auto startups of apps?i have around 200apps and most of them i use around once a day or not even once
i use android assistant to manage startup but it does on boot and after some time if i check running apps most of apps will be there running
is there any app to block it running automatically? not just at startup ? full control like anything?
thank you
actually I cannot help with that. I don't use such a software and really don't believe in it. but, the fact is that I do not use so many apps. other fact is that surely there is some useful software that could help you with that task, i just do not use one and personally I'm not interested in it. I know that perhaps the best method is to freeze them with titanium but if you use these apps from time to time then it would become complicated and not worth the effort.
still I have few questions:
why would you like to stop them from working? do they drain your battery? if so then check your logs with bbs and find out which ones are draining, try to change their setting or get rid of them, or at least close only these ones. long time ago I was fighting with some apps that I do not use often and they start themselves from time to time. I didn't want to get rid of them, so before every night I was killing them one-by-one from applications menu (actually most of them didn't wake up until I ran them myself). finally, after many tests I got to the point that it doesn't make any difference. apps I was killing, even if running, didn't use any recourses, didn't produce wakelocks, they were just using some RAM. and if it is the reason of your concern then do not be worried - they may use as much RAM as they want - android will free RAM when it will need it.
now I do not kill any apps and by night I lose 0-2% of battery which is my only concern - what should we care more? CPU, RAM - let it work as long as it doesn't stop us from enjoying our phone and make a usage of it uncomfortable.
and if you're worried about packet data then you may limit it for each app using system menu in ICS.

Thanks dude. I also have the similar problem. I have spent months on it without any improvement. Now I'm quite frustrated and not optimistic on the solution you have provided towards my issue, but your decription gives me a lot of clue.
But my problem is even more tricky, I would like to share it here so see if anyone have met it before, or if I need to start a new thread to deal with it:
The problem can be generally decribed as below:
1. When the battery is fully charged, unplug and consume the juice until the level reach around 30%, then the phone is shut down automatically; after I plugin the power and restart the phone, the battery level is displayed as 0%;
2. After charging for a while from 0% , restart the phone and you will see the battery level directly goes back to 50%, but still with very low voltage;
3. Changing with a new battery won't solve the issue -- though the new battery itself may also have problem(not sure if it is genuine), but I don't think a fake battery and an old battery should behave almost the same, so I don't think it is the battery's problem; criticize if I'm wrong
4. Re-flashing a new rom won't solve the issue either. I have tried different CM9 nightlies and now I'm using CM10 nightlies, none of them is immune to the problem;
5. Clear the battery state won't solve the problem. It is hard to say whether it improves the situation at least a tiny bit. I mean it may work somehow, e.g. My phone used to be shut down at 50% battery level and now it can last to 36%. But it never totally solve the problem once and for all, so I still don't trust this caliberation thing may work.
I hope I have clearly stated my issue. I'm so at the end of my patience, this little bastard have been always torturing me You guys are the last I can count on I really hope I came here earlier so as not to have wasted so much time.
Hi,
I've had the Galaxy player for a few months now, and I'm generally very happy with it. Although I get pretty decent battery life out of it, I'd say normally about five to ten days of idle time with roughly six hours of screen on time and about as much wi-fi on time, with maybe an additional three hours as a music player, one issue relating to battery drain appears to be constant. I'm currently back on stock, but this also happened on Eryigit -- I get very slow drain from about 100-80%, then it seems like the battery goes into freefall, going down from 80% down to 25% in a matter of an hour to an hour and a half of regular use, then slows down again until the battery dies. I tried calibrating the battery several times with no difference. I'm guessing I'm getting pretty good use of the battery overall, but this erratic drainage pattern makes me feel like I'm too often close to running out as the device spends around half the time I'm using it at 25% or less. I've read somewhere that the battery level measurement on the Galaxy Player 5.0 is highly inaccurate, and in fact is only a guess based on the voltage output of the battery. I still have to wonder though, is this a normal pattern for this device?
Thanks, Nir
Hey. I've noticed a similar pattern via battery monitor widget, tho nowhere even close to ws prononced as yrs. I generally monitor the mA rate and it goes from -2ma steadily until 80%, the rate then speeds up. W moderate usage, i get roughly 2 days out of the sgp before charging, when there's roughly 30% or less left.
I also remembr some folks mentioning that the battery wont report greater than 80%; i imagine that 80% acts a sort of border where he readings r concerned.
Try out that program i mentioned to monitor usage. Personally, im on entropys kernel and chips rom (occasionally switching to paranoid android), have undervolted it slightly, and added a few init.d scriptsl aiming for optimal battry life. Also, try out watdhdog lite to monitor any apps that might be wakelocking improperly and Gemini app manager to disable ann0ying apps from starting on boot.

Bah, I think I might have gotten a bum battery. Any idea how much screen on time/wi-fi on time you're getting with a full charge? I use BetterBatteryStats to measure, which also helped me diagnose GPS-related drainage issues (those kernel wakelocks went away when I stopped turning off the GPS, but I'm pretty sure it's a stock kernel issue). I'll try out battery monitor. Thanks!
Well, given that you can have it on idle for 6 days, it might not be thay persay
Actually, onnsecond thought Powertutor is prolly better suited for your issue. It can monitor power use per application
High display brightness; wifi that doesnt sleep even w screen off (it never sleeps by default); apps that enable things like gps, that makes requests and sends info w.o yr consent thru wifi- these, among 0ther things, drain battry life and are other things to consider

And cant say. I usually do 2-3 days before i recharge; i rarely go under 20% and dont game
Also, just caught this- gps is a huge power suck. Like huge. That may be yr problem.

It was same for me on stock rom and every other rom..70% of time from 100 to 10 it is staying on 75% and 25%..and when its on 25% it can last all day with moderate usage dont moving from 25.Its because device only measure voltage which is innacuare ,voltage dont drop linear like mah.

well i had that prob with my old SGP but since i messed it up andgot it replaced it doesnt stop at 80% for like an hour it just charges straight through tht was before i had enthropys512 kernel flashed....now the battery is faster to charge
Well, I suppose another plug for Battery Monitor Widget-
It provides a handy estimate for discharges/recharges that's proved pretty accurate. After entering the actual battery capacity and a few cycles, the app estimates charge and discharge time based upon that as well as the readings it receives. The discharge estimate isn't as accurate as I'd like, but that's probably due to my sporadic usage. The charge time, however, should be accurate since charge times are charge times are charge times.
Jeez- I should like contact the dev for a commission on the app at my rate.
Re-flashing the kernel might help, if A) killing GPS (except when, obviously, you're actually using it) and B) getting rid of those wakelocks (try Watchdog Lite-free) don't work. Eryigit's ROM, from what I remember, already has the Entropy kernel baked in
If you do some search through the past threads, you will find some discussions on this very topic.
Even though the battery performance of the device seems to be quite on par with other Android devices I have used, the amount of battery charge that is being reported is, a general guess at best. As it is, it only shows the charges and discharges only at 5% increments and on top of that, as OP stated, it seems to jump around a lot.... 100%-80% normal drain... jump down to 30% and hold... etc... heck! My device will show full charge and the moment I take off the charger, it drops to 80%... I have 4 5.0 devices and they all do that... I have stock GB, ICS and Custom GB roms and all are showing the same thing. I believe it has to do with the way the charge state is being reported... It must be a hardware glitch and I guess that is why no matter what rom you are on you will see this erratic battery % report.
I have stopped worrying about it since it does not seem to actually affect how the battery is performing.
Oh yes, I saw that post when I was skimming search results, but got fixated on the not charging above 80% part and didn't realize it was the same issue. I guess this is normal then. Thanks!
Regarding GPS: It actually doesn't seem to affect my battery life unless I'm using Google Maps, in which case the GPS flashes in the status bar and yes, the battery drains much faster. Confirmed regarding Eryigit and its custom kernel not having the same GPS wakelock issues. I went back to stock because I wanted something really light, what I ended up doing is using Titanium Backup to uninstall anything that showed up in the apps drawer or task manager that I didn't need. That made everything really nice and fast. Of course you could do the same thing with Eryigit. That might be my next move. Or maybe just try the custom kernel with the Stock ROM.

Yeah. I'm currently using Paranoid Android and it only charges to 80%. When I unplug and plug in the device it starts charging again.
I love the Galaxy Player 5.0, but it really bugs me the way Samsung so often completely abandons its customers past the point of purchase. Charging problems, bogus battery level readout, GPS off battery drain, screwy unusable GPS compass... and forget about Android updates. The US version never even got 2.3.6. I really wish there was a viable non-Samsung alternative to the 5.0, but there doesn't appear to be anything else out there that's like it.
My Nook is 10.5 months old and I have recently noticed it only hold charge for 2-3 hours.
I am still running 1.40 and rooted so I could block OTA. I haven't done any other modifications to the tablet.
Is this a common problem? I need to charge this thing everyday now, where before I could go several days without recharge.
Thanks for the help.

haven't used stock in a long time, but is there an option to turn wifi off when the tablet goes to sleep? ur wifi might be sucking up power continuously if it doesn't shut off.
Yes, that is correct, Wifi can be switch off. And I have done that. But the drain has become very significant.
I am considering going for a warranty repair, but my guess I will get a refurb with another weak battery, and hassled because I have rooted and blocked OTA.
Are most folks just running off their chargers?
If folks have bad batteries are they replacing them themselves?

you can attempt to request for a new nook tablet placement. After two refurbished replacements with the same problem as my original NT. they sent me a new Nook Tablet and so far so good. It's worth a shot.
Came off the island today and went to the big green city. Stopped at BN and did some talking with them and also to the service center at the same time. The service center said they would send me a refurb. My 3-4hour of run time is way under the 11.5 hours you should get for the e-reader mode only. That fella felt like the battery developes memory and needed to be fully discarded to combat that occurring. I can not find any technical document that supports this idea. There are not NiCad batteries.
Anyway if I send my tablet in I will end up with 1.4.3 instead of 1.4.0.
When you get your replacement
Once you get your replacement, it's a good idea not to charge it until it show very low percentage on any nicad rechargeable batteries. When you charge it, don't remove it from the charger until it reaches 100%. Also don't have a habit of plugin it in when finish using it, plan ahead so that you can have a fully discharge battery before recharging. Your NT battery charge will hold a lot longer threw time if you do it this way. You also can try this app to see if it works.

Good advise, thanks,
I put in some effort to side load the battery stats reset software and found a application call: Battery HD. I loaded this app instead. It provides a graph of the charge and discharge rate. From the graph I can see that my battery is OK. I became aware of some funnies going on when I woke up at 3 am and saw the display on. With the discharge rate as specified I now believe I have some application causing me trouble. I don't have much on the table, Titanium, MX video, Amazon apps.
I shut the unit off last night and it came back right to the same charge. Tonight I will leave it on and check the graph to see if there was an load and when. The application has a gross report on the power used separated by function instead of application. It also has a calibration test that tests the three main functions and reports the discharge rate.
Anyway, I will post what the nightly current hog is if I can find it.

My friends NT has been having issue with screen turning on by itself. Seemed to narrow it down to aldiko app. Not sure why it's happening. Performed a clean install of CM7 and issue came back. I keep thinking it's hardware related, trying to convince him to try a different ROM, but he's stuck on using CM7. If you find a reason for your tablet screen turning on let us know so maybe I can help him get his issue resolved. Thanks...

That's actually bad advice for any lithium based battery - like the NT's lithium ion battery. LiON batteries don't like to be fully discharged and they don't like heat, especially heat when they are fully charged. That means avoid full discharges and avoid charging it to full every time, and do charge the battery more frequently (keeping the charge level between 20% and 80% for example). Partial discharge on LiON is just fine; they don't suffer memory effect.

I have said it in past post, I need glasses. I totally missed this part while reading "There are not NiCad batteries" the word not always gets me.Sorry about that sgschwend. I did not even know, thanks for the info update.
Well, I always appreciate advice, my view is that it becomes a starting point and it is up to the reader to combine it with a working course of action.
As to phantom startup/turnons I checked last night and there wasn't one. I will continue till I find it. The summary screen does say what type of application is turning on so that should help. The only gotcha will be if the battery application changes how the tablet works to the point that the issue will not occur. I don't think this is very likely.
The battery application (battery HD) makes a nice graph so you can look at the slope and see what is going on, it also lists the run time for various activities based on the current battery charge. Interesting to note the Nook charger overcharges a bit and the battery does warm up some. When it cools down the charge is just under 100%. This is not an ideal situation, it would be better for the charger to slow to a point that the battery temperature is not elevated near the end of its cycle. Splitting hairs perhaps. My discharge rate matches the tablets specs even with the battery application running.
Second day of monitoring the device operated correctly. I did check and found that I have a Titanium backup batch job setup to run every day a 3 am. Which coincides with time I observed the device display turning on. I will move the time and see if the issue moves too.
Steve
Also turn off push notifications that certain apps have. They suck up a lot of battery. Install the Better Battery Stats app (search xda for it). Won't have to pay unless you want to. Monitor the partial wake locks to determine what apps are using battery during sleep.
I have a similar problem, i got a nook with cm7 and the battery doesn't last at all, i charged it yesterday and let it all night without touching it to see how long would it last and after 12 hours i got 30% and it says 70% of the battery was drained by the andoid os, it says that the processor was working for 2hrs!
i got it and stared looking for an answer to this problem and in less than 10 min it has drained 4% of the total charge, this didn't happened with the stock firmware so I'm thinking about trying jelly bean and if it doesn't get better i will have to go back to the stock firmware
Hwong, I think you hit it on the head. Last evening my NookT had a much higher current draw, loosing 20% in 12 hours. I saw this when I checked it a midnight. I had left the Nook with the battery monitor application in the graph mode, likely running as an active application instead of a "monitor" mode. Titanium Backup did run last night but it runs for such a short period it did not even show up on the graph.
So I really don't know which application or notification is causing me a problem but the issue I have had is like loosing 20% of my battery in a 6-8 hour period. Which to me looks like an application is running that shouldn't and the time I observed the screen on would do it too. As I started this post I am still on 1.4.0, rooted, OTA blocked with hidden commands.
I did a hard factory reset and wipped the caché, now my nook has been charged for 2 days on sleep mode with the wifi on.
I believe the problem was caused by an application, i believe it was the launcher and theme i was used, i re-installed it yesterday and the tablet started to drain battery quickly again so i cleaned the data used by them and uninstalled them.
The battery monitor widget use to say my battery would last 2 hrs of video playing, now it says it should last 8:30, closer to the 9hrs promissed by B&N.
It all about old sins. I found that I was jumping around in the normal Nook UI and not using the back button. So several things were still running in the background. Even though that little darling looks the same, that background stuff is a killer. I did a quick test with the battery monitor by leaving it in the graphic mode and sure enough the discharge rate went up 400%, just a dumb graph in the background plotting Voltage versus time. When I use the back button on the application graph, the current draws goes to near zero.
It really does a nice job of standby or sleep.
Maybe this will help.
You could use titanium backup to freeze the apps that you think could be causing more than usual battery drain and maybe narrow the issue down?:fingers-crossed:

If you edit these files and put you own values in then your phone will start charging when it drops below 75% and stop when it gets to 80%. (put your own values in, etc.)
I have only tested it briefly but it seems to work for AC and USB charging for me so far. No other apps or tweaks needed.
/sys/devices/platform/google,charger/charge_start_level:75
/sys/devices/platform/google,charger/charge_stop_level:80
EDIT: You need to be rooted to do this, and you need to reapply the settings after reboot.
I have a Tasker action that does this automatically 5 minutes after rebooting.
If only there was a way to use that without root :-S
What would be the purpose for this.
I always charged to a 100% and never had issues on my devices.
I use the adaptive charging overnight and think that will help with battery life.

If you do some reading you will see that charging over 80% and draining under 20% will significantly shorten the lifespan of your battery. This is important for those of us that have devices not sold in our country so getting replacement batteries would be very difficult and expensive. I have phones that are more than 9 years old and still going fine if charged like this.

Why waste 40% of your battery use....

On the contrary. The most recent phones attempt to limit the time that they spend at 100% exactly because it's so bad for battery longevity. Having options like the OP's approach just gives users more flexibility, should they want more control than, in this case, Google's adaptive/AI approach.
And it's not 'wasting' 40% of the battery. Keeping between 80% and 20% just optimizes battery service life during those days you only actually only need 60% of it's possible capacity. When working from home that's often the case for me. I actually tend to use ~30% of the battery in a day. Better to charge it up daily to about 70% than all the way to 100% and let it go down to 10% over 3 days. If it's easy to do, why not?
Not quite the same, but EV design also has their batteries normally operating in the middle range so as not to compromise their service life...
Definitely not myth. The only myth is that lithium cells exhibit a memory effect and need to be deep discharged and fully recharged periodically to maintain their capacity. It's actually bad for them to do this! The only reason to do this would be in an attempt to recalibrate the software for the battery level gauge (at the cost of a little damage to the battery each time you do that).

I always charged to a 100% and never had issues on my devices.

Most folk don't notice reduction in battery capacity until it becomes severe. For example, a friend claimed it wasn't a problem charging his iPhone to 100% ritually. When he checked the OS, it said his battery capacity was 80% of what it was when new. He said he hadn't noticed it affect how long the phone lasted.
If your usage is such that you can predict how much capacity you need, you can choose to charge to 100% only those times you will actually need that capacity. Other times you can look after the battery so it's able to actually give near on 100% for longer, those times it's important to you.
Others who keep their phones a short time or are comfortable with the cost & inconvenience of a battery replacement, or simply don't care, don't have to worry....

This all maybe good if you are planning on keeping your device for a few years.
Most people buy a new device every other year. If not once a year.
... and if you really want to knacker the battery, heat it up too!
Worst case scenario - using a sat nav app on your phone in the car on a hot day with the phone plugged into a car adaptor. It's going to be sitting there at elevated temperatures, possibly with the sun shining on it, whilst being kept at 100% battery....
I'm only a customer (and have no other affiliation) and like to tinker, so I got one of these for use in the car to limit temperature when charging and limit max charge. Not cheap, but ok compared with the cost of the phone https://chargie.org/
I'm sorry, but at the snails pace this phone charges I'd be very surprised if charging it to 100% every night will make any noticeable difference in the long run. I had a Xiaomi Mi10 Ultra with 120W fast charger. That phone used to charge from 0% to full in like 20 minutes. Now that's one way to quickly kill your battery.
The Pixel uses your alarm to adaptively charge the battery so it should never overcharge it anyway. I'd much rather us all of my battery than use it only between 20 and 80% just for it to last a little longer.
The files are overwritten on reboot so I created a Tasker task to write the values on reboot each time.

On what basis? All the research and tests are based on charge level not charge rate. Fast charging potentially just makes it worse...
But at the end of the day it's your phone. You'll charge it in whatever way works for you.
I feel like this post sort of misses the point. It clearly is aimed at those intending to keep their phones >1yr, it is stated explicitly.
I'm not rooted right now, so I've been using the AccuBattery app. One of the things it does it gives a notification every few minutes when the battery is at 80% or above so that you can physically unplug the phone from the charger. Obviously having this done automatically would be better, but I've been surprised at how well the notifications have worked in my case. Plus, I can always leave the phone plugged in if I know I need a full battery for some reason (ie a long day away from any charging source).

If you edit these files and put you own values in then your phone will start charging when it drops below 75% and stop when it gets to 80%. (put your own values in, etc.)
I have only tested it briefly but it seems to work for AC and USB charging for me so far. No other apps or tweaks needed.

Dumb question but what did you use to write values into those files? Did you use a text editor (with root access) or just termux or something? I tried with the built in MiX text editor but it seems to choke once I open up the file.

I used FX File Explorer (root option). Look for the #. SYSTEM (Root).
I was wondering if changing the file permissions after writing to them to read-only would make the changes stick, but I am sure the OS could still overwrite them...??
I wonder if there's a similar variable to tweak at what temperature the phone considers the battery is too hot and stops charging?

Did a bit of testing and it works fine. A few things I noticed:
1. Doesn't survive reboot. Now that I've set up MiX with pinned folders, I can make the change in seconds. Need to sit down and read through the acc documentation because AccA doesn't work. Would love to have an automatic solution. Miss my old Battery Charge Limit.
2. charge_start doesn't seem to matter. After all, if charge_start is set to 75 and the phone is at 70%, it shouldn't charge. But it does. I've kept mine at 0.
3. Point #2 is kinda beside the point, though, because charge_stop will stop at the set value and stay there. No noticeable increase in temperature from what I can see. Definitely less than when charging.
4. Still shows as charging rapidly when it hits the level. Is it rapidly cycling charging on and off? Or in a kind of micro-current state? Or this may be a true battery idle situation where all power is drawn from the adapter. Ampere and AccA just show "not charging".
Edit: With a bit of use today, it does seem to act like a normal min/max charge deal, so I set it at 75 start/76 stop. Not sure what was happening at first...maybe something to do with the adaptive charging since I still have that on. Either, way, no complaints. With my use case working from home, I have it plugged in most of the day and it'll only take me about a minute to change charge_stop to 100 when I'm planning to go out all day somewhere away from chargers. Not ideal, but still a big improvement. Changes my rating of the thing from maybe 3.5 stars to 4.5.
