just notice battery drain is getting worse when i tested after i charge my i9000 and left it overnight... at first, it only consume 1% after 5 hours of idle (while i was sleeping).... recently i notice it drained about 5%... an increment of 4% without any usage... does anyone here have the same problem? could it be hardware problem or should i flash a newer version of firmware to test it out? i've turned bluetooth, wifi, gps, 3g/edge off... meaning that i should have nothing running in the background... not even backup...
Under battery history (easily accessible thru SGS tools or Spare Parts), is Gallery reported as using the sensor while your phone is on standby?
My battery drains about 1% every 10 hours of standby. I had to do some tweaks however - flashed back from JPO to JM9. I'm running OCLF lag fix and 'advanced task killer' to get rid of unwanted processes. maybe this could help...
The thing is, that I'm having this issue for a while now. Battery drains extremely fast both on stock, stock + ext4, cyanogenmod, no matter what. Now I decided to install the stable version of Darky 10.1, but it's just about the same... It's like it drops 2-3% percentages in couple of mins (~10m). I'm using my phone at minimum brightness (btw, display uses 9%! only of the battery), no OC/UV, no animations, only 2g, no wifi, no gps, no account sync, so I'm like really trying to get more...
Okay, and here comes the thing: It used up 70% of the battery in less than 5 hours, and the battery stats looks like this:
Android OS 62%
Android system 10%
Display 9%
Cell standby 5%
Phone idle 2%
Dialer 1%
Dead Rider (just a game..) 1%
In my opinion, everything looks great, but the Android OS. Now what the *** is that, that this crap uses 62% and growing ?! PLease help, thanks!

Hmmm what apps r u using ? how many apps do u have installed ?
Did u buy ur phone used or from new and if u got it from new did u do the over charging for 16 hours or more ?
android OS is a huge problem for battery drain with a few causes and plenty unknown.
to fix it completely will require some skill full people from a closed source.. Download an app such as juice plotter or similar to find out a cause of the battery drain.
there are things you can do such as undervolting for extra battery life.
But the best thing to do is type in Android OS battery drain, in the search bar and have a good read up. i had this mega battery drain a few weeks back but i have it under control now

Charge your phone till it reads 100%, reboot into recovery and I think in Darky's Kernel under advanced you will see wipe battery, do this, boot your phone and let it charge back to 100%, then unplug your phone, let it die to 0 and charge again.....something weird is happening because it shouldn't be that bad....if the above doesn't work and you can rule out apps possibly you have a bad battery?? To rule out apps, wipe everything and do a fresh install of a stock ROM if it still drops then i would say it's a bad battery, but try what I suggested first (wipe battery stats)
The last maps upgrade causes bettery drain....
how to slove this problem?
Hi!
I have the exact same Problem..some say this is a bug in the gingerbread versions and can only be solved by samsung...is this true? Any ideas?
Well, I've had a pretty big read-up on it, and tested it myself, what's more tried out other things too. So I came to a conclusion, that this is absolutely true. It's said to be enough the 'freeze' the apps that cause this problem, but it's just not true. With frozen, they somehow still did it. So here's what I've done, and it looks like solved (far not as good battery life as 2.2.1, but still, at least acceptable...):
- format internal sd card
- removed the suspicious apps (msyncml, syncml, it depends on your rom, the important is, that it has "sync" it its name, and NOT account sync!)(I also removed Samsung account, and everything **** that I didn't need)
I'm having BUJV9 on right now with newest FuguMod and it looks good.
It does not mean Android OS is using 62% of your battery over the time in question .
Its a measure of what has used the power not the power drain on the battery .
Though useful on a heavy drain as your figures show display off OS using a lot but what time span at the top of your figures ..
I would guess from figures posted you have something working away in the background . A factory reset usually cures that problem .
Or find the culprit .
PowerTutor from the market may help .

I was having the Same Problems with Battery Drain. (Dropped 70% in 6 Hrs.)
It is related to 2 Services on Gingerbread.
Software Update & Samsung Account.
Clear Data and Freeze Programs using Titanium Backup and Your Battery should be back to Normal.
Huge drain on battery SGS i9000 android gingerbread v.2.3.3
I did like some other users have done I quess!?!
I upgraded via KIES from earlier version of android. After upgrade I did a reset to factory settings, but didn't set the "Format USB storage".
I installed a few programs and used the phone for a few days. After short time of usage I noticed that the battery drained really fast. Like 20% within 1 hour or so. Normally 20% battery drainage happens in a day with little use.
Then I thought something must have gone wrong with the last upgrade. Many time the tip is to clear the phone again and this time I set the "Format USB storage". It worked. Now the battery drains about 30 percent during a normal day with little use.
Since I have a backup of everything, I just installed the backup so the phone is back to normal again.
I hope this might lead to solving battery drainage issue for other users or at least and idea of what could be wrong.
First of all, I do not trust this solution, but it work to me
Solution is simple, remove your memory card from the phone
That is all
After check, found that the scan media always running to scan the memory card
This might deal to corrupted card
People say backup the data from memory card, format the card, put back the data
I haven't try format the card
But after my phone remove the card, now already 13 hours, I still have 82% and I did few phone call as well
there is an app by the name of battery calibration...follow instruction from within the app and it should solve the problem of android OS drain .. i shifted from darky 10.1 to MIUI 7.7 and 100% to 30% in 3 hours with normal usage and no wifi .. after this app battery lasted for two complete days ... so try it
There is another MORE SERIOUS BUG in ALL GB ROMs:
http://forum.xda-developers.com/showthread.php?t=1134741
After full charge in GB, phone start using batteries ONLY instead of CHARGER ONLY like in Froyo and lower version builds.
Samsung folks goofed up BIG TIME by making phone use batteries instead of charger after full charge while stopping the charge cycle. Because of this OS thinks its running on CHARGER (or USB POWER) and shows batteries as full charge when in reality it runs on batteries after full charge and will eventually make the phone dead through full discharge of batteries.
You could test this by keeping the phone connected to the charger after full charge for a prolong period. When you disconnect, based on the usage during that time, the batteries will instantly show lower charge than around 100% (could be close to 0% as well depending on usage after full charge if you disconnect charger before phone going dead at 100% drain).
Did you flashed Darky in 100% battery? The tutorial suggest you to do that. You can try to wipe battery in recovery mode.
After a difficult update with Kies I was able to upgrade to Gingerbread.
Everything seemed to go well the first time then I found drain battery and slowing down on the system.
So I decided to make a simple wipe which reported the phone as fast as at first, but the battery still has problems.
In one night from 90% it was completely drained so today I decided to use 'Battery Calibration' made from user 'marosige'. This time in 5 hours I lost 30% of battery life using some sms, internet for 15 minutes, and playing cut the rope for 10 minutes. More or less.
However I have to see if the battery loses all of a sudden like last night which is the biggest problem.
All of this is not normal have you any advice?
Thanks in advance
Hi Fattox,
Dont worry your socks off I flash Roms quite often and this requires me to calibrate the battery. Sometimes with certain Roms I find the battery may drain quickly the first time and then things get better.
You say you have calibrated so that means the app you used should have deleted the old battery stats from your systems file. In saying that if you follow these next few step you should be ok (unless there are other issues causing the drain)
1. Make your you drain the battery fully until phone dies and can't be turned on by pressing the power button then....
2. Plug in phone and keep it off until battery is fully charged. Don't take it off charge as soon as it says full. Just let it go for about an hour more or so to ensure it's at capacity.
3. Turn phone on and use as normal until dead...
Providing there are no other issues causing the battery drain you should find your battery usage to be satisfactory. Remember to turn off wifi and gps when your not using them as well as maybe turning your screen brightness down. Anything that uses less power the better....
Hope this helps.
between the recalibration with the app and your point 1, I had the same problem: during the night the battery loose all the energy.. so strange.
All this after I upgraded to Gingerbread.
I'm going to test all this week then I'll spend my warranty.
I recently upgraded from Froyo 2.2 to Gingerbread 2.3.4 and now the battery life is absolutely terrible.
Before upgrading, I would get at least 2 days of battery on Froyo. Now, on 2.3.4 a 100% charge leaves me with only 40% charge overnight.
I'm not running any background apps, I turn off Wi-Fi/Bluetooth and so on. I also turned on Airplane Mode to disable network connections.When checking the battery information, cell standby used 29% and phone idle used 71%.
I did some research, and some have related the problem to the battery forgetting it's charge level due to the OS upgrade. A solution is to factory reset the phone and run the phone until completely dead, and charge it overnight for 6+ hours or longer (imagining the phone is brand new again).
What are your thoughts on this?
What ROM are you using? ZEUS has great battery life
Sent from my LG-P970 using XDA
V20b, I updated using the LG Software Update Tool.
A system restore would not be necessary if you are rooteded, just a simple battery calibration. You can get the app on Google Play.
It will delete the batterystats.bin file that was created on your Froyo ROM and generate a new one one the Gingerbread ROM.
But then if it has forgotten, the percentage of energy left would be inaccurate thereby showing false results. The stock battery stats function is cr*p so i would suggest using a 3rd party application to monitor battery usage and current.
That would be a better indication of what is eating up your battery.
Found a suitable battery calibration app. However, my device is not rooted. If I do root my device, I lose my existing manufacturers warranty, right? My phone is less than 2 weeks old, contemplating on whether or not I should proceed to do so.
Yes you would lose ur manufactures' warranty although if u were to flash using SmartFlash or KDZU and do a system wipe, your device will be untraceable. They will never know that u rooted and u can just claim that you got advice over the phone to perform a factory reset.
Rooting is definitely worth it. It comes with its perks but also the peace of mind that any errors that you make are reversible via steps above (as long as you don't drop it and break the hardware).
You could try a factory reset if you don't want to root. Just make sure that you are recharged 100% so batterystats.bin will be as correct as possible.
Thanks for the help.
I think I will charge the battery to 100% and perform a factory reset, and hope the battery improves from there.
Will post an update later.
Same Problem
Same here, had awesome battery life on Froyo then updated to Gingerbread (V20A) using the LG updater and my battery life is now terrible. A solution to this problem would be nice. Any easy way to root my phone without having to flash it? Want to put CWM and do a battery swipe.
yes, you can have back your warranty by flashing back stock rom
my advice is to not install battery savers, just install a simple task killer, root the device and install custom roms which have good battery life
i personally use Zeus and the battery is just awesome!
or just calibrate the battery via an app as our friend just said and observe it for some days
(also, factory reset the mobile plz)
then wait for some days as the phone usually calibrates battery after a few re-charges
Update: Battery is back to normal, if not even better!
Test findings: Charged to 100% and left overnight.
13h 57m 50s later, dropped to 93%.
- Phone idle 75%.
- Cell standby 25%.
So about 1% drop every 2 or so hours, about the same as if I was on Froyo 2.2 again.
- Switched off Wi-Fi/Bluetooth/Sync's.
- Switched to 2G instead of 3G.
- Switched on Airplane Mode.
- Used Easy Battery Saver app (Intelligent Power Saving Mode).
Didn't have to root my phone, which means I don't break the warranty. Thanks everyone for the suggestions, especially FunkyGanja.
Yes...as we know the battery calibrates itself after a few recharges
Btw you can flash stock rom and have warranty baack any time

I forgot to mention that I didn't simply just recharge it again, I charged it to 100% and THEN performed a factory reset.
Apparently it has something to do with the "batterystats.bin" file, when I upgraded from Froyo 2.2 to Gingerbread 2.3.4 the battery wasn't fully charged, so GB thought my battery was fully charged at only, say 50% battery, hence why the battery drain so quickly overnight.
I also came across this post, which helped clarify my problem: https://plus.google.com/105051985738280261832/posts/FV3LVtdVxPT

There is already a battery thread here, please continue the discussion there.

Have you tried one of the battery calibration apps in the Play store? You will get some people who suggest they make no difference, but every time I've used one, I had improved battery life (or at least the reporting of the reduction in power has improved).
TenkuuHenshin
i try 1-2 time, so i try to delete batterystats.bin always when my battery will be full and we will see
Try an app called smarter wifi. It is an app that will power your wifi on and off by a set schedule.
