DISCLAIMER - I am just putting this in here so that if anyone gets any funny ideas ... Whatever you read/use in this How-TO Post is at your own RISK. The aim of this post is to help others who had the same issues as me when they were abroad ... and were stuck without a mobile Running MGLDR 1.13 and DFT stock ROM (WP7) and a USB cable but no other chargers ... If the OS doesn't boot you WON'T manage to charge via USB UNLESS you follow this HOW TO GUIDE (it's the ONLY ALTERNATIVE YOU HAVE OTHER THAN BUYING A CRADLE CHARGER) ... it WORKS 100% but I am fed up of finnicky people emailing /posting / trying to play the "experts" on the matter when they know nothing about the matter
Dear all
After going through all sorts of Registry fixes which were momentary in nature. I decided to find a viable alternative which does in actual fact work with all current WP7 builds and all MGLDR's provided with a USB Storage option.
It has been said that the WP7 Software does not charge the battery to its full potential. I also incidentally ran into the problem of charging the mobile when the battery died. Primarily because the mobile loads ... restarts ... loads ... restarts and you keep on "praying" until the OS boots to get it charged.
Alternative fixes so far which worked for me were:
- Adding android to your SD Card ..booting in android and charging it in android mode
- Charging it in Cradle Charger
- Some people even pulled out 2 wires from a USB cable (+ve and -ve) to get their phone on again (crazy and dangerious)
- MGLDR 1.12 hangs when trying to charge mobile while it is off.
- MGLDR 1.13 reboots (as a momentary fix) in order to avoid the hanging caused in 1.12
Problem is
- I can't stand the fact that we have to have 2 OS'es to get it charged properly
- I can't stand the fact the we have to remove the battery in order to get it charged externally via cradle charger
So we have to adapt to the present circumstances unfortunately. If nothing, and the fix does not give you more battery life, this method avoids you from
- buying/carrying a cradle charger with you when abroad.
- having a dual boot system (WP7 / Android) on your phone
- making you do crazy/quick fixes such as the USB cable thingy mentioned above ... (don't try it)
no need for anything of that!
HOW TO:
So in a nutshell if you drained your battery too much and don't have a cradle charger ... with the added bonus that you may get improved battery life out of WP7 is the following.
- Boot into MGLDR setup menu (hold the end call button at start up)
- Boot your mobile and hold the "End Call button" to go into the MGLDR setup screen.
- Choose USB Storage menu
- METHOD A - Let the mobile Charge for 6 hours (typically overnight would be ideal) (Note: It will not over-charge and it will not damage your battery.
OR
- METHOD B - Charge the mobile for 4 hours (to keep mobile on overnight) and charge the last hour in usb-mass storage mode. This has the added benefit that you do not get your screen on for a long time. This will not damage your battery and those of you who are worried about over-charge can go for this alternative and not take any risks.
- NOTE that you will NOT get the charging indicator ON in this mode. PRECISELY that's the whole point of charging in this mode, the battery will charge to its fullest as it is not under the influence of the WP7 software. It is like as if you put the battery in a cradle charger and charged it outside.
- When you wake up ... hit the back button to go to main menu and choose RESET option to reboot your mobile : ) and voila!
RESULTS:
- I got improved battery life charging the mobile in this MODE. I got 36 hrs + of battery life (normal usage) which is very good.
ADDED BENEFIT: QUICKFIX FOR DEAD BATTERY - NO CRADLE CHARGER - NO DUAL BOOT
- There seems to be mixed feelings about this as some of the readers have reported no discenable difference in battery performance. While I will not contradict these people, I got improved longevity from the HD2's battery. Clearly the OS is reporting the battery level badly. If NOTHING this method still serves as a quick fix
- if you drained your battery and cannot get your HD2 on again
AND
- You Do not own a cradle charger
- Registry did not work for me.
SETTINGS - WHICH IMPROVE BATTERY LIFE:
- You can optimise settings as follows in order to get my same results, again I hear many of you not wanting this as it turns of features from their PDA but as I said above, we have to adapt for the time being:
Settings are -
- ROM DFT Stock ROM original build (issued 13/01/2011)
- Radio 2.15
- Screen timeout 30 seconds
- Screen brightness set to auto
- Wifi turned off (on only when needed)
- Bluetooth turned off (on only when needed)
- Location turned off (on only when needed)
- Data Connection turned off (on only when needing to check mail)
- Email sync turned off (not every 30 mins)
- 3g turned ON - UPDATED - I got better battery life with 3G ON but this may change from country to country so I suggest that you have a go with 3G being ON or OFF and see which is better for you....)

Hi Alcatrazx,
sounds logical I´ll give it a try and report later, thanks.

Thx
Thx Bro!
Will try it later too. I'll report.
One question though... Do you need to do this everytime you charge your phone, or just the first charge?
Sounds interesting, I will try and report

Sounds like you have to do everytime... If you reboot your WP7, the battery is under the influence of the software again and does not charge correctly. Beat me if I'm wrong
Very interesting. I will try it
It's a good idea for some times, but I would not use it as an every night thing.
I sometimes get calls or messages during the night (and usually they are important). Another thing is that if you use your phone to wake you up this will not work at all.
I hope WP7 development progresses and solves this issue in the upcoming updates.
Nevertheless it's a nice way of going by, and thanks for taking the time to test it and post about it.
PS: does the light turn green after 6hours of charging or not. Probably not, but worth asking .
Another solution should be to charge a second battery in an external charger...

Another issue with this "workaround" is that MAGLDR keeps the screen opened, which can cause some devices to overheat, so be cautious with this one. I say that an external charger is the smartest alternative. I actually use this method and it works perfectly.

Sorry to sound pessimistic, BUT, people have already reported clearly in other Threads that they have tried the solution of charging their battery using an external charger with no luck. I can't see how this is any different. In addition, 6 hours will probably kill your battery in the long run (overcharging) - I have queried HTC support about it in the past.
Simple enough mate! Though 6 hours of battery charging will probably make significant damage to your HD2 battery... HD2 normally will charge in about 1 and a half hour or 2 udner WM6.5 or Android!
Not bad idea though! Bravo..
Charging while in Android remains for me the most convenient option. I must say though that this battery issue in wp7 is not that obvious for me. The phone charges quite well in wp7 and only sometimes I feel the need for a restart, after which the percentage increases with 15, not more.
most chargers since the beginning of time have a battery cut off, when the charger unit detects the polarity is starting to reverse it switches off, of course i cant say for sure using the MAGLDR method would use this, potentially it could just be a case of "connecting two wires to a battery" which as you guys have pointed out would not been good, at worst your battery could get seriously hot, or potentially if you reverse the battery polarity enough you would have half of a battery thats unusable.
I think what should be taken from this however, is that like myself and other have been saying for a long time, if your battery is charged propperly it will last a long longer, people reporting empty batteries within 20 odd hours, in my opinion, either have dud batteries or are not charging them properly
the MAJOR plus side to this post is the ability to fix the empty battery restart issue, that alone makes this idea a gold star and should be stickied!

People reporting these batteries issues my friend are people who are knowledgable enough to reach to xda-developers forums - i.e. people who have a pretty good understanding of what battery drainage is and whether their batteries are dying or not; who have installed a number of winmo roms, android roms etc.
there are roms that drain battery and others that handle power better. in the ports of Windows Phone 7 for HTC HD2 there is an issue with battery drainage, and thats a fact.
There is no issue with bat drainage but with false bat stat reporting.

your level of wit and sarcasm is actually quite funny given that you completely got my point wrong, the issue is quite simply this, the drivers for our HD2 are copies from another device, a device that is similar but not the same, the issues we have with battery are down to the fact that WE do not know if the battery is charged or not, at least at a first glance, and given the inability of many people on here to actually read threads and posts correctly it is not beyond the realm of possibility that many users dont know what level there battery is charged to, thus it may not be charged propperly.
If windows reports a full battery and its only half full then it will "appear" to empty twice as quick, now i think thats pretty clear for every one?

we cant
our phone must be different to a degree than the phone this ROM is based off otherwise we wouldnt have the issue, lets all assume for a second we can actually start chopping and changing files in WP7 like WM. We would need to find some sort of driver that exactly matches our HD2 and i doubt that will happen.
whoever made the driver isnt going to just bring out a new version for an old peice of hardware that isnt supported by MS, perhaps if a new piece of hardware has the same battery controller as us something can be done.....maybe

You have the following options:
1. Try the registry tweak. That worked for me and I actually have no battery issues for the last 2 weeks or so.
2. Charge the battery under Android during the night. That's pretty usable as you only need to reboot and you still have a fully functional phone Way better IMO than the USB Mass Storage trick.
I have a minimal Android installation on my SD (Angry Birds, you know) and it currently reports roughly the same values as WP7.

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

Thanks once again for the reply.
I tired that too every time I try to charge the phone. Still it refuses to complete the charging.
Any other suggestions are welcome.
What about off line charging ie; turning the phone off and doing that way?

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 ....

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.
From my XPERIA X10S v8.2 on JaBKerneL @ 1.15ghz
Hi,
I've got an idea to "fix" battery drain in WP7, as well as with Android.
I can't really assure you how much it's working as I do this each time I install WP7 since the first version of MAGLDR is out.
I started doing this because I had battery problems with magldr.
Here is the trick : In fact, when you install MAGLDR, Windows Phone 7 / Android, or even update WP7, the battery is not charging but draining (that kind of procedure eats a lot of power). But even if the installation ends with a 40% charge, the OS will be sure, at first start that it's almost 100% charged.
I think it's a reason why the battery goes empty faster than with Windows Mobile. It was default OS, with default configuration etc. so 100% was 100%.
So I think we must, at least once, charge the battery outside of the phone, with a dedicated charger. In that way, when WP7 will start, it will see the fully charged battery (100%, for real).
I think the OS will know, when the battery will be discharged, the real capacity from 100 to 0.
I hope it will help, and that I'm not wrong as I don't experience any real battery drain if I do this + camera trick since first version of WP7, and with any Android rom (except MIUI).
Hi
My solution is close to yours.
After each flash I let drop my battery until the phone died and you can't restart it under WP7
next I start to charge it under MARGL 5 min then i start WP7 and let it charge.
Now i'm sure that the phone have a good battery calibration.
My HD2, 2 years old, and with camera trick can stay 48 hours in 3G but only 24 hours in 2G??? WTF?
You're not completely right here, OS would not think that change at first boot is 100% charge, you can easily check that by booting first time on half empty battery and indicator will show about 50%.
But yes, battery stats might affect battery drain, so there is a button in MAGLDR something like "Clear battery stats", reboot to MAGLDR, charge to 100%, click that button, boot back to your OS.
intresting therys
What is we charged up to 100% and did a hard reset would that make the probum go away?

Oh ok. Weird, each time I flash WP7 or Android, it tells me that I've got something between a 100% and a 90% charge, which isn't possible, after having installed MAGLDR, then flashed the new OS and waited for the first boot (really long with Android).
Nonethless, I flashed WP 7.5 with radio 5.66, and I'm experiencing a huge battery drain, even with camera trick & external charge.
Even Miui seems to last longer. And Android tells me that I have a 62% battery charge, and I restarted the phone on WP and it tells me that I still have a 76% battery charge.
Why don't I have the same charge estimation ?

well I can't answer that question but I would bet android is not the 1 that is giving wrong charge estamations in on bttfv2 and I was on v1 and never experienced fast battery drain I personally like the wp7.5 over the other os's so I'm dealing with the fast battery drain issue & random reboots as well I also think the to problems are related some how the random Reboots it never happens when on on a charger! I really think someone should go back to bttfv1 to test and figure out what went wrong when new registry edits was implemented or the new rom was cooked but anyway I read DFT is also working on a new rom I'm not sure if it will be for hd2 tho.
I'm really hoping the problem can be sorted on my last phone I got about 300hrs out of 1 charge but charging touck a wile on my hd2 charging seams to be pretty quick which might not be a good thing not sure. But last night I had it on charge almost 10 hrs after it was already 100% and when I finly got it off the chager it seamed to last a little bit longer
But on rough estimate I'm thinking it last 5 hrs witch is just horrible

You're not completely right here, OS would not think that change at first boot is 100% charge, you can easily check that by booting first time on half empty battery and indicator will show about 50%.
But yes, battery stats might affect battery drain, so there is a button in MAGLDR something like "Clear battery stats", reboot to MAGLDR, charge to 100%, click that button, boot back to your OS.

Unfortunately, it's a mistake. I've never seen any "clear battery stats" menu in MAGLDR. But I think it exists on ClockWork.
It's a shame...
Battery life 24hrs+
All,
After reading the above posts, I started practicing the following;
* Let battery drain more than 90% or until critical battery warning appear
* Charge in full
* Power of phone. As the phone power off, power off charger ( ... this action may be insignificant)
* Boot the phone to MAGLDR
* Select "Reset" option from the menu
* Phone reboots normally
I have been doing this for the last 2 weeks I guess plus more than 8 charge cycles and now my HTC HD2 lasts 24hrs+ at any rate.
... I am not a heavy user, but still, I have OutLook, GMail, FB, Twitter running 15mins sync interval. 10+ calls + 5/6 SMSs a day in average. My good'ol battery keeps me happy.
... hope this helps someone ...
I found that it was my choice in SD cards that was causing battery drain. The camera trick got me down to a battery draing of -200. I couldn't understand why I couldn't get down to -7. WP7 "seemed" to be performing fine.
Switched to PNY 16GB class 4 and I think WP7 has accepted it. Have had a few reboots, but nothing I can pin on the card yet. My battery life is amazing in comparison to before. W/ wifi and bluetooth turned off, I get a battery drain between -4 and -7. MUCH better than before.
I can't get Battery Tool to work to check the drainage on Mango, but I found out that having 3G enabled, Push enabled (set mail check on "upon arrival") is giving me the best battery life. I'm using Mango since yesterday morning 11 am until now (it's 9.42 here) and I have 31% battery left.
Average usage (but it's enough for me) with internet, mail sync, twitter, facebook and some pictures.
for the record, I did not use the 'camera' trick at all.
When I disable push, and have email check set to 'manual' i'm starting to have drains and I have to use the camera trick to keep it low...
I know everybody has different results.. but I just wanted to share this, see if others can relate to this
Its pretty strange this battery drain issue, i struggled with it for months with the last wp7 rom i used.
With this rom i struggled with sd card issues like everyone else, in the end i'd bricked 4 cards of differing sizes and the onlycard i had left was the tiny 2gb sandisk that came with my HD2.
Since settling on that card i've had no issues other than storage space and battery drain is a thing of the past which could suggest that card compatability is at the heart of the problem.
Its my guess that constant attempts at read/write failure may be going unreported by wp7.
Currently im seeing about 36hrs at my regular usage, i can stretch it to 48hrs if im careful.
My wifi is on throughout my working day, i make on average 6-7 calls and send and receive 10 or more txts along with a steady stream of people hub updates.
I'm happy in the belief that i don't have a battery issue, i just wish i had more space.
So much for my optimistic post earlier, one reboot messed up the battery read. 40% left and 2 hours of usage .... I give up

... sometime back I too had the same problem, but that all changed!
if you fully charge (100%)..your phone in wp7 , it will show erroneous battery drain,...you can rectify it by restarting the phone, then use the camera trick.
if you charge till 99%.it is ok, but 100%...you need to restart

I haven't had that experience. Sometimes WP7 won't allow a full charge to happen though.
Something weird just happened.I was having Bluetooth problems.It wouldnt turn on.I then Flashed the DEv wifi plus Eu fix cab.It fixed my bluetooth but with some added treats.My battery life has more than doubled.Used to go less than 8hrs of normal use but now i hv gone 17hrs and i have around 50 % left.I didnt do any camera trick.Has anybody experienced this?
Hi, could anyone give me the link to Battery tool for WP7 Mango. Thank

Interesting article on Rootzwiki:
Wiping Battery Stats is Pointless, Says Google Jan 13 2012 09:30 PM | Ashley Glenn in Articles
Over time wiping battery stats has become a regular ritual among the Android enthusiast community. Buy a new battery? Wipe your battery stats! Upgrade to a bigger battery? Wipe your battery stats! Change kernels or restore a nandroid backup? You know what to do: wipe battery stats! But this ritual may soon become a thing of the past thanks to Google engineer Dianne Hackborn, who sheds a light on the subject that puts the tightly-held practice of wiping battery stats in the same league as carrying a lucky rabbit's foot or throwing a pinch of spilled salt over your shoulder.
Recommending that users wipe their battery stats appears in so many places and as a cure for so many ills that it has become ubiquitous. Adherents to this practice will sit and wait for their phones to report a full charge, then use an app that deletes the batterystats.bin file or reboot into recovery mode and wipe it from there. This supposedly cures a number of ills such as battery scaling issues, poor battery percentage reporting, and any of a myriad other number of issues. The truth is, according to Android Framework Engineer Dianne Hackborn, that this file is a repository for information about system activity and that it actually takes care of itself without the need for user intervention. From Dianne's post:
Quote
This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.
That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away.
It really can't be put more straightforward than that, folks. So rest assured next time you put a new battery in or flash a new kernel or restore an old backup that all you have to do to help your phone or tablet play nice with its battery is charge it to 100% and do nothing else. It really is that simple. But don't worry, enthusiasts - you'll find plenty of other reasons to hang out in recovery anyway.

This is interesting, so Google engineering will incorporate it into new OTA's? Or does this mean I've wasted time while flashing countless Roms?

Not wasting time flashing countless roms. Just wasting time wiping battery stats. That's the way it looks to me. Personally, I've always thought wiping battery stats was nothing but a whole lot of voodoo. Never had the need for it, don't see why anybody else would either. Let the flames begin.
I knew it couldn't possibly have an effect on actual battery life, but I thought maybe the file collected information about the length of the battery to calibrate the meter (because let's face it, with the X2 battery bug it's pretty clear that it doesn't get the value directly from the battery).
Funny thing about calibrating when it gets to 100 though...if there truly is something wrong with the meter, why would you suddenly trust it to know when it's charged? This is why I'd always charge it for a little extra and go by the voltage meter.
So basically, I've seen a couple of different readings. I've always waited past 100% and in different ROMs I've seen 4192, 4196, 4198, & 4200 mah.
I use the extended battery, sooooo readings may vary between regular battery.

I have an extended battery as well. Actually, I have two extended batteries and two regular batteries. Got the first one with my droid X, then a faulty extended battery (bad batch where the meter doesn't read right), then a replacement extended battery, then the one that came with my X2. No two are the same, but they should all max out near 4200 mV.
Edit: I use one extended battery.
Ok this screen is after install of CM 7 tonight, it reads 4205 mah, so why is it different, with different Roms?
Weird isn't it?

The stats can easily drift if you don't flash ROMs with your phone at 100% battery, hence why sometimes the calibration is needed [be sure to wipe stats when at 100% [either via app or recovery], best thing to do is fully discharge battery until auto off occurs and then fully charge with AC Wall Adapter and charge only screen, then when it hits 100% wait a few min, restart to OS to be sure it also says 100% [if not wait until it does and wait about 20 min longer] then restart to recovery and flash away [you could also wipe battery stats as part of flash if you do as stated before flashing]. I usually set it up so I fully discharge the phone [restarting to be sure a couple to few times] and then charge with phone off and charge only screen overnight and flash my ROM first thing in the morning right before I unplug it and unplug once I reach the point I am ready to restart device and do initial boot after flashing. Further details below...
Basically charge to 100% [or as absolutely close as you can get it [AC Wall charger is best unless you REALLY are forced to do it via USB and is best to charge via the charge only screen [phone is powered off and not booted in to the OS and all you normally see is just a battery filling on screen [and is fastest way to charge battery]]. Wait an additional 20 - 30 min after it registers 100% [this is to be sure the battery is absolutely topped off essentially] and I will generally do a restart as sometimes the battery may come back to less than 100% on a restart if your phone is not judging the battery right and is in need of calibration. If it does not register after restart wait until it hits 100% and wait the additional 20 min [you can cut out the initial 20 min wait if you want to do the restart to verify just wait the 20 min once you feel sure battery is as topped off as you can get it], then after wiping restart from recovery and unplug. Now be sure to drain the battery until auto shutoff [either stream media if in a hurry or through general usage. Either way wait until auto shut off.]. I usually will power the device back on and be sure it is not going to get back to the OS [if it even gets to boot logo I wait a few seconds and power it on again to be sure all I get is the boot vibrate on my device [some don't have this, but usually it's tablets almost all phones [and definitely both Motorola and Samsung do this]. I then charge it to full [again AC wall charger recommended as above and again with charge only, but as stated if you cant live with phone off or whatever you can do it with OS running as well. You are free to go as you wish after this second full charge really though if you do a couple more [dont have to be insane] it can help ensure the statistics get a good start.
As I believe I stated above the best way to avoid calibration as long as possible is to charge phone to 100% via phone off screen [with AC Adapter and wait the extra 20 min after it registers full before you flash [I will sometimes take it a step further, leave it plugged in while flashing my install zips and then once I go to restart system for the initial boot after ROM flash I will unplug the charger from the phone.
Hope this helps
In my case, after updating to new firmware and software my battery full capacity indicator has become sort of crazy (for the worst).
Before updating I got a solid 1390 mAh always. Now It depends on the day, but It never surpases the 1270 mAh. Barrier.
Today I´m getting a poor 1170 mAh.
Strange thing.
Anyone else experiencing this issue?

From my review, my battery seems to be getting better now, first week after the update, battery was dreadful, it seems to be a whole lot better now. Give it a week, if it continues, email Nokia support, since you hopefully have your warranty, they'll check and replace it if it's faulty, I'm suffering from some horrible notification bug, that's worse, getting your notification when you enter message/whatsapp...-_-
Have same problem. The last update have reduced full charge capacity from 1420 mA to 1303 mA and it's still decreasing every charge. Hope is's soft bug, otherwise nokia should exchange killed batteries phones.
Nokia says not to trust their diagnostics tool when it comes to degrading capacity. The battery should be fine anyway unless it reports less than 1000mAh.
Nokia's biggest mistake was making the Diagnostics available to every user. Now everybody thinks Nokia stole their precious mAh...
Note: It doesn't even matter the update gave us some hours in autonomy.
Yep. Without it most users would actually enjoy their phones.
So the Diagnostics tool gives a bad reading?
Today, when I plugged the charger off, the charge percent inmediately went down from 100% to 98%. Maybe there´s some kind of software bug thay doesn´t give the real battery performance.
P.S.: I actually enjoy my phone. Love it.

This happened to me also this morning. Took my phone off charge, unlocked it and then was at 98% but going to keep an eye on it throughout the day. I got roughly 15 hours use yesterday and 5 hours of that was when i was at work.
I am getting terrible battery life after the update. 100 % at last mid night. By the morning it is at 85%. It seems the battery life got worsen by a 40 % decrease before the update.
Should I restore my Lumia 800?
I get weird battery issue on my latest 800. About every second charge the battery drains very fast doing nothing. The next charge it is fine. Next after that it can drain. And so it goes. Something fishy with software indeed. It was preloaded with 11501 from factory so I have not updated myself.
Nokia need to take a detailed look at this. As it is now they fully think the issue is fixed when in face it is not. As the topic implies it actually made things worse compared to old firmware. Those 15% charge that were lost in old firmware it lasted longer anyway because it had no drain.

I have made a factory reset just for the heck of it. Also I have recently started rebooting my phone with the charger plugged after every charge and then unplug when it is booted again. So far no drain after doing so but too early to make any conclusions.
I reseted the phone on a charge cycle with drain and after the reset the drain stopped. So something weird is going on. Hadn't really installed apps etc... syncing/location etc off...

Unfortunately I do not even have the good days result. After I updated my Lumia to .11500 my battery drains really quick with doing nothing. Before going to sleep I had about 60%, waking up it was empty, in 6 hours! Before I could last about 1.5 days with my phone. Hardly 10 hours with normal use. 3G on but wifi and bt off.
Does anyone know how to change this or to change it back to the earlier version of software?
I love this phone and its OS, but the battery consumption is just wrong!
Thanks.

Same issue with battery drain. Not that frequent though. Two times in two weeks. It´s random I think. Thing is that I´ve noticed that it has occurred when the phone shows maximum than my average battery capacity.
Normally phone shows 1170 mAh when fully charged. Strangely enough I get a very decent battery life. More than 24 hours with normal to heavy use.
But today it showed 1370 mAh fully charged and it´s not passed 12 hour barrier.

Since I made that factory reset the drain has not come back so far. Now I get good battery life and it's usually at 70% when I go to sleep at nights with moderate use throughout the day.
Is this what everyone is doing for best battery or is it just me?
Used to get heavy drain when I get the mobile:
I had to do below:
1) Location services off - i use very low though.
2) Removing people tile
3) Display brightness - LOW
4) Settings->Applications->Games->Connect to Xbox LIVE-> OFF
(with ON, used to drain battery alot atleast for me)
5) Settings->Background tasks->Weather->Off
(not sure of this, but I don't use it so I switched off)
6) Removing XBox Live Tile (In fact all live tiles like App Highlights etc...)
7) Date+time -> Set automatically -> OFFFF (I don't think we need it unless we go to other country)
8) Phone Update -> Turn off notifications
By the way,
I use push email outlook on always

What to do. Now a days all smart phones come with great features and poor battery life.
By the way, anybody knows how to turn off fast dormancy in our lumia 800? I used to get much better battery life by turning off fast dormancy in android phones ( obviously my network is not supporting the feature though)

So you're limiting the phones key features for a battery problem? Why not contact Nokia? I must be honest, if Nokia were to tell me to switch off so many features of my phone, I would tell them to kindly p*** off, as I've had many phones before it that didn't pose a problem like this, if it's a fault, they should act to it, not make you rectify their mistakes. At the end of the day, if you broke your phone accidently, would they fix it for you? So why should you?
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 ;-)

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.

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.
