i'm using donut's android build and this battery/charging problem is driving me nuts. my battery lasts 4-5 hours max and the weird thing is it only takes 10 -15 mins to show my battery is fully charged. i tried flashing again, left the phone until it dies by itself and charge it, left it being charged over night but none of them helps. anyone having same issue? i know with android on our vogue the battery life sux but is it this bad??

might be time for a new battery. It should take 30 to 45 mins to charge. And it should last longer than that. How much time do you spend playing games ect. Gps also is a battery drainer. Also alot of data usage.

My battery can last all or most of the day with moderate use on Android.
If you are running off an SD card, try booting back into windows for a day or so to see if you have a similar battery problem there too. Actually, windows battery life was MUCH worse for me. The difference is that Android does not wake the screen for Calendar alerts or text messages like WinMo does... though in Android you do still get the vibrate or sound alert.

win mo is actually quite ROM dependent (NFSFAN's ROMs got awesome battery life). android is pretty kernel dependent. if you are charging overnight, and using latest zimage/kernel, and turing off syncing (background data), and that is the battery life you are getting, you need a new battery.
i use gps a lot as i work as a field technician but i don't have gps turned on all the time while im driving as the screen shuts off by itself in a minute or so. maybe gps is still working even with the screen shut off? and it's a nand install so trying with winmo is not possible. i had much better battery life with winmo for sure. if i turn off the syncing will i still be able to use gps?
Which NBH are you using? The newest ones are way better than the older ones. If your using a current one check out tatnai's FAQ... http://forum.xda-developers.com/showpost.php?p=5599516&postcount=33

It's the kernel. you know the file you rename RUU_signed and you flash.
I am definitely having this problem as well, and the charge does not last very long it seems either. Was much, MUCH better in the Windows Mobile builds I was using previously.
I am on Bell using the basic HTC Touch
Same problem here. Brand new battery on bell.
Yeah, although battery life is positively improved and pretty decent now, there is definitely still something funky going on with charging. I still don't rely on / believe when the phone says it is fully charged. It happens too quickly to be possibly true.
I have the exact same issue and it is absolutely a problem with charging within Android. I have two identical batteries. One was fully charged in winmo before I flashed - I took it out and swapped for the other one. Flashed it with that battery in and charged it overnight. It only lasted about a half-day. Came home and swapped out for my other fully-charged (in winmo) battery, and it lasted for more than a day. Same settings, same use. After it discharged, I recharged overnight from Android and it behaved the same as the first - discharging in about a half-day.
What gives?
I'm curious what builds people are using? I'm totally new to this but I'm using warm donut with voguimg-240x320-06-04-10.nbh. It seems that nbh isn't posted on the sourceforge site yet - maybe I should switch back to an older one?
Maybe kernel problem.
I'm experiencing the same problem as everyone.
Lately my battery suddenly drops from 100% to 4%.
When I put to charge, it reaches 100% very fast. Should reach only 5%
I think it can be a problem in the kernel.
Now, i'm trying to solve it. If I find something I'll share with you
I can not determine which kernel brought the problem...
23/04 - 16:16 (GMT-3 - Rio de Janeiro) - Trying an old kernel
23/04 - 17:00 - Nothing. But came to the conclusion that the problem is with the battery.
Battery really "thinks" its 100% charged, since it accepts flash a nbh without the need of the phone is charging. And this only happens when the battery is at least 50% charged...

My battery life is pretty bad and I recently bought a new OEM battery. Coming of NSFANs 6.5 rom, Myn's warm donut on 240x320 is wonderful but the battery life is pretty lousy.
Not sure if this is a problem with the captivate (Rogers I897) or if it's just a select few, but I noticed last night despite the usb charger being plugged in overnight, once the battery reported full, it stopped charging.
So basically, I got home from work, plugged in my captivate because the battery was rather low (only takes 24 hours of maybe 30 mins to 1h of actual usage before I get below 40%), and it took 4-5 hours to charge completely. When I unplugged it in the morning though, it was already down to 64% with just being idle all night.
So is this normal or should I ask for a replacement battery or something?
There are a lot of posts around here about batterirs dying quickly, and "charge death", but I'm not really sure whats going on with your phone. All I can suggest is that you make sure that you close all apps and stuff before letting it idle, and just see how that goes. I suppose you could just have a bad battery. Are you on a custom ROM or stock? I had problems with battery life when I first flashed to a custom rom, but since then I've switched to serendipity 4.3, I have it undervolted, I keep an eye out with a task manager, and my phone has no problems lasting all day, even while texting a good amount/using it for searches and stuff.
What ROM are you running?
Did you have GPS/Bluetooth/Wireless left on?
There are known issues with certain builds of ROM's causing this issue. If your on a stock ROM and still having this issue? I would take it in to possibly have it warrantied out or at least have the battery replaced.
I haven't ever had an issue with my phone losing a charge while plugged in.
Yeah, stock ROM. I haven't installed any additional task managers, but I usually open it up and kill all tasks when I'm finished with them.
I do keep bluetooth and GPS off at all times, but I leave wifi on overnight because I didn't think the battery would stop charging entirely once it was full. I've only had the phone a week so I could get it replaced, I just wanted to investigate it a bit to see if it's a common issue or not before I did that.

Settings --> Mobile and Network --> Wifi Settings --> Advanced (soft key) --> When screen turns off
This would turn off wifi after 15 mins of inactivity. This would help save ur battery.
And yes, charge does get cut off when left for extended times, but not right after it says charge full.
Recalibrate your battery/battery stats. This is my method, there are many others though:
1. Charge the phone with the phone ON, until the phone indicates full battery
2. Unplug the charger, replug, continue charging until full battery again (I repeat this 2-3 times)
3. Turn off phone, charge until full battery
4. Unplug the charger, replug, continue charing until full battery again (Again, I repeat 2-3 times)
5. Turn on the phone, let the phone charge yet again.
6. Boot into Android Recovery, delete battery stats (Advance -> Wipe Battery Stats)

Cool, I'll try this, thanks!
By default, wifi does get turned off when the screen goes dark and I haven't changed it.
I've also been tring to flash to a new ROM (been trying Android 2.2), but Kies won't load my phone). I think I'll research other methods when I have time.

If u r not heavy on data and use it for things like mails and chats, and esp when in an area with no proper 3G coverage, u can switch to EDGE and get out of 3G. 3G sucks more battery compared to EDGE.
So I wasn't able to complete all the steps to kind of fix the battery problem, but I plugged it in to almost 100% (I think it was like 98% or something, I had to go out so I had to unplug it), but when I got back I plugged it in again and let it charge overnight. This morning however, it was still at 100%, and now, about 8.5 hours later, it's only at 73% so I think maybe it just had to normalize it.

Give it some time to normalize. And charge showing 98% when unplugged at 100% is normal.
And yes, seeing 60% battery left after an hour of calls and tasks involving an hour plus of display on after a day's work, apart from push emails, etc (~14 hours standby) isn't so new anymore to me.
Stop watching the battery so closely for about a week and u'll be all set
I was on darkys 8.1 rom with jk4 modem, calibrated the battery one time and I went 18 hours. Starting from 98%
6 hours were phone calls, 1.5 hours of text messaging. 2 hours of power amp . The rest was pretty much just standby/idle time.
Though, I don't get that anymore though.. Jk4 has gone to **** for me. I used to get full signal majority of the time, and for places where other people go no bars, I got one or two. Now its pretty horrible it makes me sad ;(

Hello all,
I have a brand new Galaxy Tab ( three full charges so far) - and I get quite different results re. battery life then others.
Then again: I read some posts with really long batt life, and others with shorter.
I have Gingerbread - Overcome RC1 installed, and I in about 1.5 hours use ( no 3G, some wifi, medium backlight; time spent mainly installing / removing apps, some games, some email and web browsing) I am at 75%.
When the unit is fully charged, after I switch it on it goes to 99% immediately (I see 100% maybe for less than a minute). This morning I am at about 65% battery life, with about 2 hours use. ( I have erased the battery stats after installing the Overcome rom).
When not using the unit for several hours (for example over night): I do a complete shut-down.
Now others seem to get significantly longer run times.
Is it possible that there are (at least) two versions of the GT, one with better battery the other one with weaker battery?
Or do I have a defective unit and should I try to return it? ( I am within the 30 days return policy, and could go for an exchange)?
Or is my experience totally normal, and the "really long" battery lifes are more the exception?
Or will my battery life get longer after a few more charge / recharge cycles?
I would appreciate any feedback!
Thank you!
People claiming better battery life are running custom firmwares, have their cpu moderated, and have pulled all kinde of tricks to achieve this.
Also, your battery has to "settle"
Sent from my GT-P1000 using XDA Premium App
Thank you for the reply.
I am also using a custom firmware but no other tricks (slowing CPU etc.)
So my unit is then probably normal?
How long does it take for the battery to reach full capacity?
I think I will return the GT for replacement...
Another update.
Yesterday, I have done a full recycle ( fully empty the battery and fully recharge).
Today, when I started to use it, within 50 minutes the battery level went to 80%.
I have removed now all apps, all widgets etc ( factory fresh gingerbread) and I will fully charge and then reset the battery memory within CW.
Lets see how that goes... but I start to worry now as my return period has just passed ( 14 days from purchase) - so I may be stuck with a unit with a battery problem...
I would reccomend to stop delete battery stat everytime now and then. Another thing is please wait few cycles so battery will settle down as someone said. When I got my SGT for the first time I was quite worried that my battery drain so quick. Simple internet browsing over wifi last for 3-4h. Later on I found tha some apps sync itself constantly, name pulse, weather widgets, rss readers etc. Ive check the apps and disable auto sync. Also moving from 2.2 to 2.3 gives me huge boost and make battery last muuch longer.

Thank you. Lets hope you are right.
Install the version beta2. The battery on it lasts much longer. I checked and returned to the beta2 since RC1. Only first JJ4, then JQ1 and beta2. My English is not good, so I apologize if I wrote something wrong
Wow. That is an interesting theory. I will definitely test: you well may be right. I have used beta2 only for a short time, but I think the battery did last longer...
In beta2 worked for 11 hours. The RC1 is less than 7 hours. A friend has the same. Both went back to beta2. Wi-fi enabled, much inernet ,radio, Google mail, mp3. Used on a single chargefor more than iPad
Same problem here..
Strange it is. .
So far i know. .

For me it has always been a big differens in battery life after a couple of weeks when the battery is performing better.
In the beginning with stock rom i barely got trough one day with heavy use.
Now its no problem getting trough two days of heavy use. Using Overcomes (rc1) latest rom.

I would deffinitelly recommend going back to beta2 as in my case on rc1 I was able to get maximum 7-8 hours when switching to beta2 gave me at least 12 hours. At the moment when not extensively using the tab I am able to get around 60 hours.
ps1
as someone mentioned before pleae stop erasing batterystats.bin
ps2
Do not try to install beta2 on rc1 as it wil cause you a lot of problems. Start with jq1 at least and then beta2.
Hello,
I had the same problem too, but I have resolved it now.
I started by browsing this thread:
http://forum.xda-developers.com/showthread.php?t=986067&highlight=false+status
Then I opened up my tab and disconnected battery for 30 mins. Reconnect and close up and that fixed the problem permanently.
For some people, flashing overcome 2.0 rc1 solved their issues.
Hope that helped.

Hello guys, sorry for my bad english, but I'm not American. Well, my question is:
I bought from a guy a Galaxy S I900b, Brazilian model with digital TV. Came with stock 2.3. As I had already read enough before, upgraded to JWB Saurom with semaphore kernel, which I think is the default for this rom. Well, the phone had very poor battery life, evn on idle. Then upgraded to 10.2 CM. I saw that had some wakelocks, and with BBS and the help here, I used the Scan Media Root and my problems are gone in iddle. So, my phone goes into deep sleep and today during my sleep, only lost 3% battery, 3% battery drain on idle during about 5-6 hours it very good to me. But during use, it ends up very fast, and with GSAM and standard monitor of the android, I saw that after the screen, the Android system was what had higher %% battery. So what could it be ? The battery life is ok, checked on info, and its condition is 'good'. I use to Greenify, and close almost every game\app, so running is just grenify and ram manager pro.
So the prob just could be a app or the 'android system' ? Or even hardware ?
I dont have much time now, so any info or screenshot you want, I can provide later
Thanks
What about your connections? Do you have 3G/wifi enabled at all times?
calibrate....maybe useless, but u can try....but somehow, try bigger mAh battery, maybe.....n maybe .... it will help.
juz charge it with screen turn on till it full, n waste it to 0% till it shut down, turn it on n charge it with screen on till it full again, u ll be fine
if problem occur again, keep an eye for sneaky app that run at background (email...exchange etc) n juz delete some sys app that u dont use using titanium.
if it still occur again, wait for arc reactor battery....

I've deleted the batterystats.bin and used until 0%, so charged while off, but nothing :C
It's true that the battery needs to 'learn' ? Like, a few charges and discharges and could estabilize ?
I'll take a few screenshots right now
Callibration of you battery eg: Wipe battery stats is onluy helpfull when you get weird battery stats.
If you are on any CyanogenMod ROM you have to get used to the higher ammount of battery use by the phone. The application Greenify can help a lot by hibernating the huge battery suckers like facebook and google maps.
Some tips:
- use 2G instead of 3G
- Turn WIFI off when you're outside the house or leaving for some time
- Turn GPS/Bluetooth on only when you're about to use it
- Dont use taskkillers (they are used to free up ram but killing apps makes android restarts them and this consumes extra juice)
- Put brightness on Auto
- Use a dark theme and background/lockscreenwallpaper
- Dont recharge your phone when below 5% this can damage the battery
- A new battery needs to "Get used to" the life of being a battery xD After a few recharging cycles it will work like normal
Here some screenshots, if need more, just ask
Note: Was with 14%batt, rebooted and drops to 11-10%

brightness is on low
I really dunno what 2 do ... almost 1 week with it and this insane drain, everyone says that plays or browser on wifi and get almost 10 hours... my dream this happen to me lol
Remember that this is just on use, on idle it use virtually nothing, like I said, almost 3% on sleep, but is just I start use with app or browser and its gone
Screens are from a too short period of useage. Use it from fully charged, and make some new screenies This can help futher
Well i got problems with my battery too so im planning to buy a new one because this one cant even handle 3-4 hours when im doing something like playing games,or listening music...Just buy new battery with more mAh and dont get bother with this :laugh:

It looks like wifi and 3G have been kept on for most/all of the time. Turning those off while you're not using them may significantly increase battery life.
Also, related to kernels, personally I've found Mackay to be a bit better in terms of battery.
Also it looks like your screen's pretty bright if 61% of the battery usage is because of it. So if you don't need it so bright turning the brightness down may help.
Start by doing those, and see how your battery life fares first- if not much changes, then it may help getting a bettery battery/changing rom even.

So, like i said, in this 2 hours after charge, i've used opera mini with wifi, I dont use 3g. Right now the battery is less than 10%... it's strange since have people telling that can use almost 5 hours wifi and the battery is > 50%
And the brightness is at lowest bright :\
The problem could be some corrupted file ? I have the options:
- format EVERYTHING, and dont use titanium backup, since somthing can be corrupted.
- change my kernel to Mackay
- change my room back to SAUROM 2.3.6 adn semaphore kernel
I'm very sad cuz I have a very old Nokia E5 that can be on with wifi almost or more than 10hours ... and this phone can barely hold 5hour
What u suggest me to do ?

How long have you been using the rom? Roms take time to calibrate the battery and this is through charge/discharge cycles.
Alternatively, go into Performance settings and change the profile to powersave/conservative (it differs from rom to rom). Lock the min CPU frequency to 200mHz- apparently this helps.
Again, this would change depending on your kernel.
And if you have a three year old battery like mine, best not to expect miracles...

Now i've formated everything and will put a stock 2.3 and see in a couple of days the perfomance ... if gets better, I put the saurom 2.3.6 and be with it, cuz 2.3.6 on brazilian model allow to use digital tv, and 2.3 everyone says is economic.
I'll get this updated if my situation changes, if not, will buy a new battery
Thanks for all your help
Note: How long your batt last ? With high\low usage
Hello!
I know that there were a lot said about battery problems in 4.1.2 android, but i still haven't found any solution on my problem. My Note was bought with GB 2.3.6 and had an awesome battery, but after i updated it to JB 4.1.2 (via Kies), suddenly battery life is catastrophic. I have everything off (bluetooth, wi-fi, gps), my screen brightness is on minimum, i use my phone on GSM band (not 4g), i also disabled some of unused apps, etc...everything said was also my practice on previous version 2.3.6 and phone battery lasts up to 4 days, but now, it drains off in 17hrs and I barely use my phone!
If I check battery stats, it shows that screen is the major consumer of battery and it seems like it is on all the time, although the phone screen is physically off most of the time. It means something causing my phone being awake all the time instead of being off.
Any ideas how to fix this??

4 days? really? think that is unheard of. Either how, it should last longer than 17 hours.
Try going back to factory settings, perhaps theres something running thats divided by zero :silly: .
If you feel adventurous you can also choose to root & try a custom rom. Though thats your responsibility and choice entirely.

Yup 4 days, not kiddin...4 days of average use.
I forgot to mention that i already did the factory reset and i also wipe the cache partition in recovery menu... I disabled practically everything, and i use things when i need, nothing is set on auto, sync or anything. Last night I didn't touch the phone for about 9 hrs and battery consumption was around 1% which is ok, but it's draining everytime i turn on the screen like 5% in 10mins. BBS shows that well known GTALK_ASYNC_CONN as a battery eater. Is it possible to kill this annoying thing on un-rooted phone???
