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:

I wished i could get a original 2000mAh battery in Pakistan

0,4% / h on standby on CM10, synchronization every 30 minutes

I was able to lower battery usage to 0,4% per hour on standby on latest QUARX CM10 (measured by BatteryDrain). That's the lowest I could get from Defy ever.
With this and when using defy only to communicate (mail, phone, sms) I could get easily 4 days on one charge.
My settings:
- SetVsel - 17/300, checked "Limit to VSel1 While Screen is off"
- CleverConnectivity for managing 2g/3g, WiFi and synchronization (synchronization occurs every 30 minutes)
- About 100 apps installed, full Google Apps for CM10, disabled Google Location services
I think radio (2g) eats most of this so propably it's impossible to go lower - or am I wrong ? Does enyone was able to get lower standby battery usage ?

I get 0.3%/h on standby.
With WiFi on and downloading, it goes more that 8%/h.

Install the free app "wakelock detector" and disable or remove any app that is waking the phone up or using too much cpu power.

I removed all bloatware from the phone, used Greenify to hibernate misbehaving apps, Better Battery Stats to find wakelocks and what not, and the usual: lower brightness when you can, disable any gestures or smart features you dont use. Turn off wifi, Bluetooth, and Location when possible. I also underclock my phone to 1.6hz for most of the day.
I get around 24 to 48 hours depending on usage, and around 5-6 hours screen on time.

how to underclock

You need to be rooted (I think)

delete new skype app (old version doesn't wake up the phone)
delete facebook and instead use a browser bookmark... the app is always running in background.
delete ALL samsung related **** and other stuff you don't need.
my problem was wlan_rx_wake which was solved by buying a new router.
i had a fritzbox for 130 euros which seemed to flood my network with some data.... only android phones woke up because of this.
bought a new router for 18 euros... problem solved.
****in piece of **** :silly:

LoL and also Log Out from instagtam when not using!!!!!!! wastes most of the Battry also delete apps you dont use and dont use a live wallpaper!

[Q] Betterbatterystats help

Hi, I need help to figure out why I'm getting so more much awake time than screen on time.
According to the partial wake lock stats audioout_2 is the one that keeps waking up my phone... Tho the time running is not very high so I'm a little confuse here...
Is anything else I'm missing here??
Thanks
PD sorry for my bad English

hi..
Audio out 2 is the touch/screenlock sounds.
try disable and monitor it in BBS again in few hours' time.

Playing music will cause AudioOut_2 wakelock.
I get it when using any music player.

Hi, I already have touchscreen wakelock sound disabled.
Using wakelock detector, I found Facebook app is draining a lot of battery, but I'm not sure If that's the app that causes the audioout_2 wakelock.
I downloaded greenify , so I'll try add the app there.
Thanks

Hi, at the moment I'm not using my phone for playing songs. Maybe some other app? I've read that viber could cause this wakelock, I uninstall it but still the same.
Thanks!

whatsapp is another wakelock culprit preventing yr device to deep sleep..
what I would suggest to u is to unchecked sync contacts in whatsapp setting.
that would minimise the wakelocks if u still intend to use it.
so does exchange mail service..
maybe try to change refresh intervals to 4 hours and monitor it from there.
nlp collector is caused by location is being turned on in yr device settings.
turn location to off if u want it to go away.
and after 4 hours, post a dump file from BBS here again, mate.
other things to look at BBS is the high number of counts on each services running in the partial wakelocks.
besides these, there are more..
