[Q] HELP NEEDED. Battery problems - Galaxy S III Q&A, Help & Troubleshooting

My galaxy s3 i9300 is draining the battery fast.
It hardly last for 5-6 hours on standby.
At first I thought it was jelly bean 4.3 that caused the problem, so I removed 4.3 and installed 4.0.4 but the problem remains.
Then I figured the battery must be problematic so I bought a new one, follow the instructions on how to handle new batteries but still it drains it fast.
It drains it with 4.0.4 and with 4.3.
No apps are running in the backround, it drains it on a fresh installation of the OS.
I really don't know what else to try.
Can any one give some help or pointers?
Regards

Hundreds of identical threads, search and read for more information.
If you are running stock firmware then you have many apps running during standby, disable or remove all Samsung apps and greenify the rest.

I did search, nothing helps.
The only samsung apps I have is samsung link and samsung push service.
What do you mean by "greenify" ?

URGENT!!! Battery Drain after Samsung Apps Update

Guys! This is SERIOUS! EVEN AFTER UNINSTALLING the Samsung Push Service and the other Samsung Utility and also freezing the Samsung Apps using Titanium, the battery drain continues! Nothing has worked. Battery going from 100% to ZERO in less than 3 Hours! Does anyone know what is happening and how to stop this???
I think the only option left now is to reflash the ROM. I was on XWKK2 CF-Rooted which was working great till this damned Samsung Update! The battery is LOSING CHARGE even when plugged into my laptop! I don't know how I'll be able to get my battery back to 100% to reflash the Rom.

I wrongly pressed the thanks button..
Anyway, charge the phone while off for a couple of hours and try reflashing a fresh firmware.. Maybe that should do the trick..

Now all new apps can be installed only AFTER I flash the ROM again. Waiting for the battery charge to go over 50% level so that I can flash the ROM.
Have reflashed and re-rooted the ROM. Looks like it has solved the battery drain problem, will know for sure by later tonight. The overheating of the phone is gone and it's back to normal. Don't know what the problem was yet, but started after updating Samsung Apps. Have frozen both Samsung Apps and SamsungAppsUNA now.
some more users reported that they had battery drain after installing that, i hva no problems however

I have followed your advice of freezing samsung apps and samsungappsUNA via autorun manager.
Prior to that been using Rarity rom for weeks, great battery life, well over 24hrs with heavy use and then all of a sudden after updating some apps (the 2 above mentioneded werent part of that), my phone has started to heat up and the battery drain is very fast (5% in 30mins), before it would go few hours without 1% loss.
Trieed looking at the updated apps but no luck so have tried your advice before i reflash wipe which i dont want to so praying this works.
Even tried flashing different kernels but no luck.
*cheers for the advice, battery life seems to have gone back to normal

SGS2 ICS battery life

After upgrading to ICS (via kies) the battery really sucks. Last for a whole day if im lucky. Is this normal??

From what I've heard, it's usually improved - BUT some power management bugs that affected stock Gingerbread kernels but were fixed in all custom kernels are still present in ICS, such as the good old fuel_alerted wakelock - so while it's better when working well, it's more prone to breaking.
I'm happy if my battery lasts for a day as i'm always messing with it(one of these days I might use it to make a phone call)! Have you tried putting it on charge at bedtime? I find that helps a lot.

I would try to avoid over-charging it, it's not good for any battery. Once it hits 100% (so long as it's correctly calibrated) unplug and use as normal.

same here i upgraded to ICS xxlpq and have been using it for 3 days, im struggling to get a day out of it ... its exactly the same setup as when i ran XEU (KI4) 2.3.4 unbranded UK. I noticed ram usage has increased as well as the amount of system processes. both times I rooted and removed bloatware. when my contract runs out in 6 months I will be looking at either a pure asop phone or an iphone 5, The galaxy s2 has a great screen but the batterylife if weak no matter what custom rom and custom kernal is running. Also I can get a wifi signal in my bedroom with my laptop and my old iphone 3gs but nothing with the s2.
Also please can anyone advise what the best pure and minimilistic asop rom will be for the galaxy s2 ive read cm9 mite be soon but is there anything thats great for battery life ? ...... thanks for you time in advance :=)

did u manage to fix the problem is "exchange something that can be removed ?
Upgrading to custom ICS roms is usually a great way to enhance your battery life, because they're always containing tweaks and optimizations!
This worked for me
Device: GT-I9100 (Samsung Galaxy S2 international)
Carrier: Smartone
Country / Language: Hong Kong
OS / Browser / build number (if applicable): ICS 4.0.3/IML74K.ZSLPE
I can confirm that I have resolved the battery drain issue after upgrading to ICS on my device. The problem was partial wake locks caused by the exchange service.
One of these measures fixed the problem for me (it might have been any of these, although I have a strong suspicion that the factory reset is the only relevant one):
- factory reset of phone; didn't restore the settings and accounts, but set them up manually
- wiped cache
- did not reinstall ADW launcher
Hope that helps.
The good news is that now the battery life is definitely better than it was on Gingerbread.

This isn't really true. Once it hits 100% it pretty much runs off the charger.
By depleting it all the time you are ruining the battery that way

Leaving your phone on charge longer than is absolutely necessary ie taking it off charge as soon as it gets to 100% will not affect your battery life and there is also no need to manually calibrate the battery. I installed DXLP7 and was getting poor battery life due to a wakelock, I found and dealt with the cause and immediately battery life improved. In my experience battery life on ICS is as good as it was in gingerbread. Better battery stats is your friend.

I had upgraded my sgs2 to ics yesterday. The new version is draining the battery very seriously. In the previous version, my sgs2 could last for about 12 hours from a fully charged state. But now the version can only last for 6 hours, which is really unacceptable.
Is deep sleep? You can check with CPU-Spy. If not, remove the battery a few minutes and then returned.

I had huge battery drain issues from exchange and email waking the device and constantly doing something. Removed the accounts and then set them up again. Like night and day now, better than gb. On LP7 and never wiped.
Cheers

Keep a look with BetterBatteryStats, and see if there are any apps messing up.
I have better batterylife with ICS by a margin.
And about leaving the charger on during night, these are kind of myths really, you can keep it on without any worries, and also charge it without being totally drained.
Most of these thoughts come from the old Ni-Cd times with memory effect.
I had removed the Exchange Account yesterday and the battery drain problem disappeared. The account was added back after about 10 hours. The battery usage is now back to normal (a little bit better than the situation before the ics upgarde). Thanks for your hint.
Cheers.
SG S2 ICS Battery drain issue
Had upgraded to ICS when it launched in India and literally went berserk due to the battery drain issue. Googled and googled, found a lot of things, tried most of them (except for changing ROMs).
Then, Voila, last 4 days - a complete twist to my sorry tale. I first disabled the phone backup option (to Google), did a factory reset, said No to most of the options that are asked on restart, and didnt install the earlier applications from the Play store en masse (earlier, had a number of games and other 'what I thought was useful' apps). Now, only have the basic apps plus Poweramp, Shazam and NQ Mobile added. And the result - the battery is back to normal. Phew....big relief as I use the phone pretty much for mails, music, phone.
I want yo add some thing very annoying, I discovered today after upgrading to Resurrection ROM.
In fact, even with the device connected to my car power supply and using Copilot for about 1 hour, the battery continued it's discharge instead of charging.
So what to say and what to do?
Cheers

[Q] 4.1.1 battery life

hello everybody
after upgrading to 4.1.1 from my provider, the battery life seems to have decreased a lot
in battery status, majority of power drain comes from android system, which i dont think is normal
has anyone observed a similar behaviour? just to know if is a problem of my phone or a problem of this sw release, before i roll back to 4.0.4
baseband version i9300budli1
kernel 3.0.31 256827
build jro03c.i9300xxdlih
thanks and regards
gm

I have the same problem as well so you are on the same boat as me
Stock JB uses more battery than stock ICS. It is a known issue
Not true. Your comment is not based on fact and is thus completely meaningless, so stop misleading people.
Provide evidence, based on which Stock ROM and kernel, your own sync settings, Apps used above Stock and Battery use with BBS log output.
And whether you wiped everything or not (as this is critical).
maybe not the right place where to ask, but is there a way to roll back to stock ics without having to reinstall all applications and data? as it has been possible to upgrade from 4.0.4 to 4.1.1 without losing user data.
havent found a way so far, i have all backups, but just in case i missed something...
thanks

ok was not so straightforward to find out but BBS should stand for betterbatterystats. installed and will look into logs
do you think that wiping everything out and installing a fresh 4.1.1 would solve the issue?

Doing a clean install is the first stop, then go through all your settings and check what you have enabled by default.
Also Google now uses a bit of battery due to location services, but imho it's worth it!
havent changed any setting after upgrade. afaik, google now is not enabled, and all location services are currently disabled.
still battery like sucks. one day with very scarce use of data and voice.

Wipe the lot format sdcard.
Install rom only .
Turn everything off sync wifi gps .
Charge fully and leave for about twelve hours .
Check drain it should be between 2 and 5 percent .
After adding back apps you will probably find a far higher drain = your apps not the firmware .
jje
Should be getting something like this... light use, hourly syncing etc. So about -2%/hr
JB UK (BTU) Stock rooted.
Note that it is important to charge to 100% (not 99%) at least once some time after flashing to reset the fuel gauge correctly. The battery performance (or more accurately the battery monitoring) improves over the first few days of normal use/charging.
I tested both stock ics and stock jb. And stock ics has a better battery life for me... btw if you turn off all motions and extras like smart stay you should get better battery life.
I theory jb should have better battery life than ics but I didn't noticed that.
P.s. I will post bbs stats next time i flash stock rom (probably not so soon )
If I have misleaded someone I'm sorry

Phone battery draining quickly after JB update

Hi,
I have recently (half a week ago) updated my SII to Jelly Bean from ICS. It's fully stock without root. However, I noticed right away that the battery started draining very quickly and the phone sometimes gets hot. Did a factory reset. Factory reset the phone and format the internal SD and remove the external SD. Didn't help in the slightest. Phone starts draining after resetting. I have tried to flash another stock JB ROM (XEU) and afterwards factory reset the phone again. No dice. I installed CPU Spy to see CPU consumption and it says the phone didn't go into deep sleep at all and 95% of the time it was at 200 Mhz over an 8 hour period or so. So there's a wakelock that's keeping the phone continuously on.
At first, "Media" in battery settings in Settings was the culprit, it drained about 50% of the battery. I have searched the web and it's a pretty common battery drain on JB. I did try to disable the service and its battery consumption went down dramatically. But for some reason it turned on again. But right now Android OS and Android System are both draining most of the battery. I have also installed BetterBatteryStats and according to that app there is a partial wakelock called "NlpWakeLock" by Google Services that's draining most of the battery. Last night, around 60% of the battery got drained overnight (80% > 23% to be precise). Which, clearly, is unacceptable.
I'm at my wits end. I have no idea how to solve this and because I really like the new JB features I don't want to go back to ICS (I did a fresh ICS install and the battery drained 2% overnight which is how it's supposed to be).
If there's any information you need to know let me know. Any help is appreciated!
Go back to GB with speedmod kernel is an option.

Do you mean going back to Gingerbread? I haven't figured out what the speedmod kernel is yet but if I were to switch back I would rather switch back to ICS. But preferably I'd stick to JB since I do love all the new features and options. I'm willing to flash another JB ROM without the battery drain issue. However, all stock ROMs that I have tried had the issue.
Do you know of any good JB ROM? I prefer to keep it as stock as possible. I did root when I had ICS installed though.
Battery Drainage is very common in JB Stock

Hey Kaigo ,
I have faced the same problem as you have faced ... Gone through a lot of problems to fix this Many of the Stock JB's for GS2 are having a lot of issues with the battery drainage
Well I had found a solution to this problem You can try installing the JB France update (XEF) & the UAE update (XSG)
It worked pretty well for me Try it and let me know if it worked for you

Well repeating other peoples posts isnt helping anybody.
An update. I've installed the XEF update initially it had the same draining issue. However, I've also cleared cache and data in recovery mode and it seems to have solved most of the issue. I've got pretty good battery life now (about 1%/h idle).
But I did find another culprit draining the battery which is Dropbox. According to BBS the processes "wlan_rx_wake" and "h2_hsic" were draining the battery but I've uninstalled Dropbox now and it seems to have solved the issue. I really use Dropbox regularly though. Anyone got any idea what could be causing that?
Thanks for the help so far everyone! :laugh:

I have always had that feature disabled since I don't want to use it anyway. I have no clue what could be causing it. I want to use a packet sniffer to see what is sending and receiving data but the phone isn't rooted so I can't really do that unfortunately.
Hold on, I'ma freeze it with TiBu.
Test time.
PS: You really need to root that phone.
Sent from...this is not even my S2
I just greenify Dropbox (actually, all apps which rely on an internet connection). Unfortunately for you, it requires root. IMHO, almost worth rooting for, although there's many better reasons than that.
Greenify is almost like a temporary freezing of the app, by stopping all background processes for the app. They automatically restart when you launch the app, and automatically turn off when the phone goes to deep sleep.

Well Dropbox always keeps on syncing stuff from the cloud and that might the real cause You should disable all the automatic syncing and keep it to manual sync as it syncs only on your commands and saves your battery!!

Check how much data is being downloaded. If a lot is being downloaded off WiFi, switch it off and see if that stops your drain. Then switch off Data on your cellular. Just to check which one's causing the drain. Believe it or not, I just rebooted my home wifi router and battery drain issue was over on my Galaxy S2.

I had previously rooted my phone when I was on ICS. I never used it too often though. I wanted to use Nandroid. I have no clue how to root JB though, without flashing a modded kernel (which I did with ICS).

That's very interesting. This might just be a good reason to root the phone. So I can use network log or shark to see which apps are sending and/or receiving data. I have this feeling Dropbox is going to be one of them..

I just greenify Dropbox (actually, all apps which rely on an internet connection). Unfortunately for you, it requires root. IMHO, almost worth rooting for, although there's many better reasons than that.
Greenify is almost like a temporary freezing of the app, by stopping all background processes for the app. They automatically restart when you launch the app, and automatically turn off when the phone goes to deep sleep.

Hmm, but I guess that you can't really freeze apps like Whatsapp, since you wouldn't be able to receive any messages then until you turn on your phone. But I'm getting convinced to root the phone again so I'm definitely going to give it a try.

Help! Battery draining fast [ 4.3 stock rooted ]

Hello everybody, I need help with my draining battery of SGS3 I9300.
Before updating to 4.3 OTA official, the battery lasted a day of normal to heavy use, ~ 3 hours screen on time, but now I barely get 1-2 hours.
If I unplug my phone at 12PM, by 7AM when I wake up it is already 88%(no gps wifi bt vibration or data+ power saving on) If I use it I can see it draining in front of my eyes while just web browsing for 10 minutes it goes down like 4-5%.
I never keep gps bt wifi or data on, just when I need it and screen timeout is 15sec and brightness is auto 0.
Power saving does not do anything helpful.
Here's the usage for a regular day.
as what others says,, 4.3 eats alot of battery compared to 4,1 .. you may think of having a custom rom with tweaks that saves battery...
You could try installing a program to watch for wakelocks if you have rooted phone. Then you can observe what wakes your phone up Especially if you say its like 12% at night.
Try wakelock detector to see battery draining apps or just flash a custom rom.

Have you flash any stock firmware? In that case, it's possible that the drain comes from new firmware ....
Just buy a 4300 mah battery

As you rooted... uninstall all the unwanted system apps ... use Greenify to hibernate apps...

I have not.
I have disabled several apps via Greenify, here's a wakelock screenshot afterwards.
Anything unusual ?
Try factory reset and see if it helps.
How old is your battery?
1. Disable unused applications (Mostly Samsung Bloaatware).
2. Greenify your applications.
3. Use Boeffla Kernel, with JustArchi's Ultra_PowerSave preset.
4. Try to use dark wallpapers.
Try Archidroid 1.7.16 rom.. It's excellent

Well it's around over a year old.
I had to replace mine just recently and it was not a year old. It behaved like yours too. :/

The best way is a new battery its not so expensive.
:good:

Doubt it.
Those OTA can perform quite a number on your phone. Best way is to check for apps that are draining the battery and maybe perform a clean installation, disabling those crappy OTA updates.
