Hi
I just noticed in wm61 that I can chose not to charge the battery when docked to the computer. Will the battery-lifespan increase if I only charnge when empty instead of all-the-time?
In my experience the lifetime increases if you recharge the battery only when really necessary. Especially in the first weeks you should be careful to let the battery run through a couple of complete cycles!
ok thanks!

Couldn't agree more. The old bs about fully discharged and then charged fully where applicable when we had NiMH-batteries.

Maybe it's voodoo, but I followed the procedure described in my first posting with many, many different Li-ion devices and my batteries work better than those of my friends, who don't let them run through complete cycles.
It's not voodoo - it's just calibration (when device don't know current capacity of battery - it can not charge battery completely... some discharge-charge cycles - and device knows everything).
I received my Touch HD a couple of weeks ago and since that time it has spent most of it's time switched on, connected to the PC via USB and constantly charging, while I mess about with software and skinning, etc. Last night, I took the phone out fully charged. I didn't use the phone at all, four hours later, I went to use the phone and noticed it was switched off, so I switched it on, and it said the battery was very low then switched off again. Does this mean I have ruined the battery through the constant PC connection or could it be some other reason, like BT and WiFi constantly scanning for connections, etc? I have noticed that the phone gets quite warm when switched on and connected to the PC for extended periods. This morning I have re-attached the phone to the PC without turning it on and it is still charging after over two hours, which suggests that it is still accepting a reasonable amount of charge.
Neofilis, it all depends on what you are running. If you are using wifi, the battery will be empty fast. If you use aebutton+ or other software that uses CPU while idle, that will empty your battery fast too. Push mail or pull mail (last one depends on how often you sync) will also be a battery drainer, but not as fast as wifi.
It might also be that your battery is not OK. In that case, you can make use of your warrenty, specially if you just bought the device.

Hi this is my first ever post so please bear with me, my lumia like many others suffers from ridiculous battery drain I have the new software and yes I can now charge to the max. However the battery cannot last the day out until I discovered this. Most people I know continually top up there battery, but if you just let it completely die then do a full charge overnight you may like me notice a massive increase in battery life, I have changed nothing about the way I use my phone the only difference is it now lasts 2 days easily.
The figures quoted in battery saver have not changed but as the day goes on the time since last charge goes up but so does the estimated battery life.
My phone is now IMO fantastic.
Maybe if you tried this it might work for you too, do hope so.
One word of caution when the phone has died the phone cannot be switched on until charger has been plugged in for some time, in my case about 20 minutes after plug in the phone switches itself on.
Please try and maybe you will also have the most amazing phone too.

I think I experienced something similar. I then flashed the new firmware and am back to lower battery life. Need to take the time for a few discharge cycles.
The problem with this approach is that some Lumia 800's cannot turn on after a full discharge. People have gone to great lengths to be able to get a tiny bit of charge so that it could power on. Some people have had to send them back for repair.
Question to TS. Do you let it completely die every time now or can you charge it whenever and still get the great battery life?
battery fix maybe
Hi after letting the phone die I have not done it again since, I just top up as needed or at night just as you would normally do.
Hope this helps.
Okey. When you say "completely let it die" do you mean letting it drain and turn off. Or do you start it once again after the first turning off and let it die again?
battery fix maybey
Just use the phone till it turns itself off, then plug in charger, this is when you may have to wait for the phone to switch on, mine turns itself on after about 20 minutes, charge as normal then use as normal, charging as you would normally do.
Good luck.
I did this once intentionally about two weeks ago. Did not notice any difference really. I do not have "bad" battery life to begin with. Not great either though. But it easily lasts a full day with heavy usage which is all I need really.
12 hours since last charge. 73% left on battery. I have used it "normally". About 10 quick calls. A few messages. Browsing on the marketplace installing a few apps editing contacts etc...
I'm pretty heavy on my usage, too. Lots of Mix Radio, sometimes played via bluetooth.
Hey Everyone,
I apologize if this is a repost. I know I read somewhere (I believe here) about a similar issue, but I couldn't find it in searching.
A little background - AT&T SGS2 running stock rom (2.3.4), rooted, using a custom kernel (2.6.35.6) I got off of here.
Anyway, my phone has been working great for months. All of a sudden, my battery indicator is completely wacky and innacurate. It seems to have started after I came back from a trip and had to put it in 'airplane mode' a few times.
The battery level indicator goes down very quickly, and is not a true indication of my phone's charge level. I noticed it a couple days ago (after we came back) where after about 6 hours, I was down to 40%. Normally after a full day's usage I am still at ~80% by the time I get home from work. Since my phone had been running for weeks without a reboot, I decided to reboot it, thinking maybe I had some overzealous background processes running. It came back online with the battery indicator at 8% (down from 40% a minute prior)! After about 30mins or so, it began to go up, and settled around 14%. It stayed at this level for hours, until I plugged it in when I went to bed.
The next morning, same thing, it would lose 1-2% every few minutes until it got down to <10%, where I would get a warning about a low battery level. But once it hit that mark, it would stay there for hours and my phone would work perfectly fine.
As I mentioend above, I thought I read a similar story where the recommendation was to turn the phone off, charge it up all the way, and then turn it back on after it was fully charged. I tried that last night, but my phone is down to 87% after only 2 hours of non-use.
I've made sure that UV/OC'ing was disabled, that no background apps are doing anything weird, etc. And it's not like my battery is really dying quickly - it's just that Android thinks it is. I've checked the level using multiple programs, and all report the same incorrect information.
Does anyone have any suggestions on how to fix it? Thanks!
You have encountered two separate issues, one of which is widely documented (fuel gauge reaction to rebooting), one of which is unexpected but possible on UCKH7 (abnormal drain).
But it doesn't look like the battery is really draining that much quicker, only that it's showing that it is. For example, while it might take me only 3 hours to go from 100%-10%, I'll stay at 10% for hours.
It's like the battery is no longer calibrated properly.
Do you use Samsung original charger? If not, try. It should go away.
Take your battery out for a few minutes. The SG2 differs in that it uses a chip for battery calibration/stats. You need to cut power to it completely to reset it. Now, if it still does it afterward, either the battery is faulty, or the phone's ability to measure voltages is wonky.
Also, are you using the phone's Power Saving mode? Maybe the battery is dying but the phone is taking steps to make it last longer?

I used to never use my Samsung charger and never had issues. However, months of using my blackberry charger has rendered it now ineffective. The charger dongle was slightly smaller, and its continuous wiggling messed up my phone's power port slightly. It's a good thing that my Samsung charger still works.
When we were on vacation, I was using my wife's charger for her phone (T-Mobile G2x) so we didn't need to take two (seemingly) identical chargers with us. My understanding was that the pinout and voltage were all the same, so I didn't think it would matter. Maybe that had an impact?
Normally I use my Samsung charger, and have been since we got back.
I haven't tried removing the battery yet, since its in a hard shell case and was hoping I could resolve the issue without taking it apart. But I'll try that tonight.
Power saving mode is disabled. I've also disabled BT, Wi-Fi, GPS, and shut down every app. In the time since my first post (84%) and now, I'm down to 58%, and my phone has been sitting on my desk unused the entire time.
According to the built in battery monitor, Android OS accounts for 92% of battery usage, with Display at 3%, Cell Standby at 3% and Phone Idle at 2%.
As I mentioned above, I thought I read something about a 'trick' to reset the battery gauge by turning the phone off, charging it to 100%, unplugging it, and then turning it back on. Was I mistaken?
Thanks for the responses.
FYI - I just pulled the battery, let it sit for a minute, and plugged it back in.
Battery level went from 58% to 39% after it powered back on.
I'll try charging it again to see if it has any noticeable impact.
Oh, I did want to mention that I've been very religious when it comes to charging my phone properly and trying to "take care" of the battery. I never let it get below 20% (outside of recently due to the issue), I always charge it up to 100%, I never do quick "let me just charge it for 15 minutes to make a call" type charges, I always use a wall charger and not a car charger, etc.
Down to 38% during the time it took me to type this...

That to me sounds like you might have an app creating a wakelock and preventing it from going into deep sleep.

With the exception of high load immediately following a reset (which is why it goes funky on a low-battery reboot), it's basically impossible for the fuel gauge to go out of calibration. It's designed to continuously converge towards truth.
Check the raw battery voltage when it seems to be funny. If your voltage is consistently low, you might be experiencing a hardware failure (like maybe the battery's protection circuit is on its way out.)
After pulling the battery, putting it back in and recharging it, it seems to be working well now. Too early to say for sure, but I went the entire afternoon and evening (up until now) with some mild usage, and am only at 84%. So far so good!

The phone has a voltage drop which causes the drop from 58 to 39 when you reboot it. I'm not a fan of it either.
I really enjoyed the S2 guide(somewhere here in xda) about tweaking the phone so as to maximise potential battery time.
With the increased battery of the S3 I know its not as big of a deal but I'd still love to see a few tips on how to go about getting as much juice as possible from the battery on the S3?

I think the first few charge cycles to any battery determine how well they perform, I have put my S3 through 4 full charge cycles so far and the longest life I've had out of it is a smidge over 36 hours with fairly frequent usage, I'm looking in to optimisations for it but I think the charge cycles are key to good long term performance.
Would you mind explaining what a charge cycle is?
Sure..
Basically when I first got the phone I put the battery in and left it charging for ~16-18 hours before I even turned it on, next morning unplugged, turned it on, went through set up etc.. hammered it all day until battery died, went through the same process again (repeated x4 so far, on 5th full charge now)
It is important to charge fully then discharge fully a few times to allow the battery to exercise and calibrate its maximum potential.
After this partial charges are fine, but worth doing a charge/discharge/charge at least once a month to allow the calibration to remain good
Hope that helps,
R.

It's not necessary to charge up the phone before using it the first time I was told. If you drain it first time then proceed as you said afterwards its still basically the same thing imo.
Cool. Thanks for the responses. I'll definitely try one of these methods.

I'm not saying it's necessary, but if you want to condition the cells correctly it is advisable.

That is not true, a technician told me that newer batteries doest have to be drained and fully charged to perform optimal. It WAS neccesary back in the day with the older devices and no smartphones etc.
It is clearly marked on the directions to charge fully before use
Hello everyone. First off, I have read this - Things You Should Know About Lithium Ion Battery. Secondly, I know this smartphone has a weaker battery than most, which combined with a dual-core 1ghz CPU makes it drain in about two days on average (I am an entry-level user). However, I've managed to optimize battery life through various options and by staying on factory Android (2.3.7) so now it can last to about four days, so I was very happy. Now more about the 'incident'.
Usually I charge my phone at home on an unused wall socket. But this time I charged it at my friends place on an extension cable which was literally packed with cables and his PC stuff. First thing I noticed is that it took a lot longer to charge my phone. It took nearly two hours to charge my phone from around half capacity to full, while at home this is usually accomplished in 30 minutes.
After this I've noticed that battery life deteriorates much quicker, it now lasts about a day and that's when just idling and not doing anything (!), so I'm back to the state before I managed to prolong battery life and even worse.
So what happened? Did my phone suffer irreversible damage to the battery?
As much as I can tell from a layman point of view, the AC flow on that extension cable felt 'unstable' so maybe it means the battery was charged with 'lower quality' current?
Now every subsequent charge I do at my home improves battery life for the first few hours, but after a point it still deteriorates rapidly and that's while my phone is not even awake. I get the feeling I should let it discharge completely (even though this is not advisable for Li-Ion) and charge it fully from zero to full capacity? Kind of letting the battery format again in normal conditions maybe?
Much appreciated. Luka from Serbia.
Here are the screenshots (cant post full links)
imageshack.us/f/706/wt9e.png
This is how my battery life looks after 22 hours. As you see, most of it was when the phone was not awake.

Even using 2.3.7 that's not normal... your problem it's not from that "episode". It's from the past
i am havin HTC AMAZE 4G
when i used to charge it before
phone used to come to 90% from a full in approximately 1 hour.
now it comes very quickly like 10-15 minutes
& also the major problem is my phone gets switched off at any battery percentage like 65% & when it gets restarted it comes to around 8% or sometimes even 4%.
if i pull out battery again restart the phone then sometimes it comes to around 30% back or any random increase in battery or sometimes even decreases to 4% & then the battery gets drained in 5 minutes & i have charge it again
battery takes more time to even charge
sometimes using DATA & charging it even takes 10 hours to charge
i dont know what is the problem
i have been thinking about battery problems
but i googled & in some blogs it shows as circuit problems too
the problem is i am living in INDIA
this phone is not official here so the service center guy wont touch it & i dont want to waste money on the battery if it isnt the problem
USING HTC ICS OFFICIAL ROM
NOW BATTERY LASTS with normal data on maximum 4 hours
help me out guys
thank u
How old is your handset? Battery life decline is normal as it ages. Without being able to inspect and test yours out all I can tell you is the most likely explanation for what you're describing is battery wear.
The original HTC battery that came with my phone only holds 2/3 of the charge it once had when new, which is why I invested in a pair of Anker batteries and an external charging station (I purchased them together in a package on eBay for under $30 US shipped). Having the extra batteries has been an excellent addition. I alternate them every few days to more evenly balance how they are wearing and to prolong the remaining life of my original battery. Plus it's great to have an extra battery to use for those times when I really need my device, but don't have the ability to plug in.
Check out the best battery thread in the Amaze accessory section for more details and comparisons.
I hav been using this phone for 1.5 years
tried using battery of my dad he uses same phone.
It showed 56% in my fathers phone
Wen i switched the battery &; started my phone it showed 15% at start
So what could be the problem then?

You're getting the different results because the batteries aren't calibrated to each phone. If you put your fully charged battery in your father's phone it shows 56%, correct? What happens when you put your father's fully charged battery in your phone? Keep in mind that when switching around the batteries neither with be calibrated to the device, but will instead show a percentage vs the battery that was properly calibrated.
Example: the battery in my phone shows as fully charged, but is worn and no longer charges to the maximum. If I place it in my brother's Evo 3D which uses the same size battery but is newer. It will show as only partially charged because his device is calibrated to his newer stronger battery. Conversely, if I put his newer battery in my phone which has been calibrated to my older worn battery it will appear to be fully or nearly fully charged for a long time before it begins to show it's draining with use.
The only way to properly test your battery would be to either try a known stronger one in yours for several charge - discharge cycles as your phone calibrates to it, or to try your battery in another device for several such cycles. Then you need to compare if there was an improvement in up-time or not. Short of taking it in to be checked on diagnostic equipment it's the best method I can think of.
Good luck!
Thank you very much for the reply
Goin to a local mobile repair guy for a hardware check
Will tell you the results tommorow
Thanks once again
Maybe you just need to wipe battery stats. One trick that works is let it drain completly and let it be drain over night and charge it again keep doing a couple of days it may just get better. But think is just battery problem not hardware related.
My Original HTC battery worked its way down to 2 hours of usable talk time. Eventually, got so bad that it barely charged on anything but a high current wall charger. Technically it was under warranty at the time...
Ordered 2 Anker Batteries w/ charger for $30, and not long after that the charger broke. It quit charging batteries.
I then just stuck with one Anker battery in my phone and the other as backup. The battery I used the most is now down to about 4 hours of life on a full charge. The least used is about 8. I try to keep the worse one charged up as a backup in a pinch and now use the good battery full time.
Just how life goes sometimes...

Yeah that Anker charger is the weak-spot in that 2 battery package deal. The damn thing is flimsy and fragile. I'm so paranoid about breaking it I treat it with kid gloves. The batteries are pretty good though. The package was one of the best investments I made since owning the Amaze. Using indelible marker I labeled them 1 and 2, and rotate their usage with my original HTC (which is easy to distinguish). This way when I'm on the road I always have one fully charged spare handy, one charging at home, and one in my handset.

Agreed!
But When I was using official ICS from T-mobile, I had the same problem, even after wiping. I even faced a funny thing. Percentage of battery in bar was different from percentage shown in lock screen!!!
After flashing custom rom, All problems GONE!
