Poor Battery Performance of my S 2

Hello everyone,
My S2 only last for 10-13 hours and it drains battery too fast. Tried everything and nothing happened.
In my phone i disabled almost everything which drain battery.
No Facebook
No auto syn of Gmail
Access location is off.
GPS Off
Soft key light/Vibration off
No skype
Disabled Accu weather app
Disabled many others bloat ware
Brightness is set at almost zero level
Better Battery Stats show connectivity wake lock. i think ghis the main problem for drain.
And plz tell me how can i set my phone to only gsm. There is no option for that in phone. In setting it says GSM / wcdma and only wcdma. I set it at gsm/wcdma. Am from Pakistan and here there is no 3g/wcdma.
And if by dialing *#*#4636#*#* i choose gsm, it comes back to gsm/wcdma. Is it draining battery?

<nvm, didn't read properly...>

what ROM are you using ??

What!?
You wrote "My S2 only last for 10-13 hours and it drains battery too fast."
On attached screenshot you have 80% left after 6 hours of usages whereas 48% is used by Screen and 17% is used by Boat Browser.
You have to expect about 1~1½ % drain per hour ... even if you don't use your phone.
Screen drains a lot depending of your amount of Brightness! If you can get 4 hours Screen On, your happy.
From what I can see ... your battery time is totally normal!

I have Stock rom ICS 4.0.4
My cellphone is branded version and it comes from 3 Mobile UK.

no its not normal.. today i charged it and not use it for 2 hours.. i put it on airplane mode and leave it for 2 hours after 100% charge, to check the partial wakelocks.
I thought this time connectivity service wakelock doesn't appear but it does.
i thought connectivity service wakelock is due to mobile signal but when i put it on airplan mode for 2 hrs this partial wakelock still appear.

Hmm , I am not a Fan of ICS though, but the battery time which you have shared (Just Saw it) LOL , it is totally fine , and secondly , use a safe kernel to root the phone (PhilZ Kernel) link is in my signature , and then Flash NeatROM Lite v4.0 , my battery lasts easily 18-20h and i am a heavy user of the phone with Calls , Messaging , FB , Twitter, Whatsapp, Viber & Tapatalk

PLS STOP with all this Juice Defender nonsense! A task killer often will drain your battery even more ... some processes will just restart again after you have killed it.
On newer Android version (GB and ICS) I haven't found any task killers that actually prolonged my battery time.
Adjust your screen brightness as low as possible, use a dark backgrounds and themes, get rid of unnecessary Widgets and Live Screen backgrounds, Sync Mail, Calendar, Twitter only when needed ... and then you will be fine :good:

Heat problem and battery drain on i9500

Hello all! I just wonder if you guys have the same problem that I do, after about 4 minutes of chilling in menus or doing something that wouldn't use CPU much causes heating at the top and top-back of the device and by that time battery just drains.
My device is i9500. I flashed Wanam's kernel (Adam V1) yesterday night to see if anything would change, but nothing has changed so far.
All of the gestures and stuff are off and the screen brightness is set to automatic.
I just wonder if you guys have the same issues.

I do have the same heating problem while using less cpu intensive tasks and battery is draining fast even if its in standby mode(i mean when still screen is off).

Same.
Huge battery drain issue and serious overheating on the i9500

I'm just sitting and waiting some updates, patches and fixes like everyone else. Missing my Note2 :crying:

try running betterbattery stats and see what is hogging your battery juice
hope it will show the cause of the fast draining

No issue here. I've been using the AT&T version of the S4 for the last few days. Playing games & web browsing for extended amounts of time. I haven't felt any heating on the device thus far.

iv got serious issues as well...
apps like nova launcher using so much??
apps usage greater than screen usage..

Well guys, I have charged it full and then after 15 minutes I have used BatteryCallibration app to wipe battery stats (It needs root), drain is not changed but the heat problem seems better. I will use it for 1 or 2 more cycles then post the situation.
And I will try to flash another modem.
Ext. SD is unplugged btw.

You can try many things, also the remove battery if you want to do that, its a firmware fault, I even tryed running total stock for some days after full recovery, it comes back. Only fix i have so far is restart the phone a few times untill it works again, then it can work for few hours or sometimes a day. resetting cache moving battery etc. shouldn't help at all. atleast I dont see the logic in removing the battery if you wipe cache...? Someone please explain what els you achieve!

Yeah I'm having the same " android os" wakelock since the latest mj7 update and it's killing the battery! Reboots didn't help much, I'll try the advice above for clearing cache and if it works

For how long have it worked for you? I tried this thing aswel, still ended in a no deep sleep state.. :/

What @onyxogen said makes sense now. I know that on one or 2 occasions, my battery lasted normally and i think i might have started using it right out of the socket. I mean start using it after battery full while still plugged in then disconnect later. But i did it without knowing then... I will try for real now and know for sure.

I did. Doesn't work

I posted this in many posts so far, because I am ****ing mad about no quick optimization for this "so called flagship"! The no deep sleep problem is ****ing huge, they must install something into the kernel that can regonize what apps have multiple uses of alarm_manager or something!
In the end, this problem is nothing we can do anything about. As it is samsung/android that have made the problem. I even tried this restart phone and unplug from charger while screen are on... My phone since 6hours ago have had 2m and 37s deep sleep..
I think it is so poor, that we pay so much for a phone and then the only thing samsung do is just put their trust in having android kitkat fixing it, instead of being proactive....

This would only work if it would be the only reason that stops your phone from entering deep sleep of course, so it's far from sure that it works.
For me it works since 2 weeks, but I have to repeat it every time I disconnect. Sometimes I have longer periods of no deep sleep but if I just plug it out while charging than the bug appears every time if I remember correctly.
It's an partly known android bug, since 4.1 I believe.
Note that you have to use the display for a while before unplugging!

Hmm gotta try use my phone for scrolling forums and mail in the morning then.. didnt know that I would have to use it for some time first.. It actually sounds like that could be the problem, if you say its a well known bug since 4.1... because everyday i do get it fixed after a few resets and then it works rest of the day... untill the next day when its been charged..

glanceviewservice causing huge battery drain

Hi Guys,
Bought Note 3 few days back, biggest battery drainer as I see from better battery stats is "glanceviewservice" as kernel wake lock.
I dont even use this feature, is there a way to disable it ?

[Q] Kernel (Android OS) sucking my battery !! Can Anyone help ??

I have GSam battery monitor installed on my Note 3 (SM-900) running stock JB 4.3 (MK1) ....
Since a last few days I have witnessed battery drain on my phone without any apparent reason....I charge my phone to 100% at night (wifi & 3G data is off at night) & when I wake up after about 8 to 9 hours of sleep I find that the battery is down to 85% !!! Strange isn't it ...
GSam battery monitor says that nearly 67% of battery is used by "App Usage" , on clicking App Usage for bifurcation of battery usage I find that nearly 50% of my battery is used up by "Kernel (Android OS)"......How to control this , any help will be appreciated dear forum friends !!

Please help me regarding this unusual problem....

honestly it is not the real cause.
i personally dont turn off these 2 options, and dont have problem with battery.
but sometime (ONLY sometime), the Android OS also eat my battery. Just reboot the phone and no more problem
So try to reboot your phone?
