Have u update to 2.3.6? Saw is some forum tat the batt life for phone can.last up to 2 days. But i think tis need forumer who runs on 2.3.6 to verify.

Thanks.

Modem: I9100GDZKJ2

ROM:
Build Number: GINGERBREAD.DZKJ2
Android Version 2.3.6


Nope I din use pirated except GPS but seldom run it. Other than that are all from Android Market.

Hrm...it seems like I'm the only one who having this issue. Everyone using non-G and I'm using G version. Damn! G version always have more problem! Sooooo regret for my 1st Samung phone

Moderate usage impossible to last 2 days..for me it's usually around 15hours

If mostly idling then 2 days is easy peasy

im using the official 2.3.6 about 1 month. didnt notice any improvement on battery life. only some changes in UI

I am running 2.3.6 as well. No problems on my side.

Well, turn off the GPS receiver.

Did you download betterbatterystats from the xda forum?
Go download it and report back.

Whichever way should be fine. Since you're gonna flash a kernal, do that first, then thunderbolt (follow instructions)

After u flash a kernal or whatever in the future, follow pikachu's xda thread (think 2nd post, or further down in first post) which tells you to go to particular folders to see if certain files there, or run something in terminal emulator, do determine if tb is there

I'm on the latest version. I thought my screen is big that's why sucks lots of battery but the problem is this is AMOLED, should be saving more energy isn;t it and I din't scale up my brightness. Everyday fully charge, the next day I wake up sure left 30%..... everyday is charging phone man. Damn I wanna go Samsung there diao them haha

thanks! u saved me sometime as i was gonna do Thunderbolt first....

Doesn't sound normal if you lose 30% while sleeping. Even on stock and G version and everything, shouldn't drop that much if you manage properly.

You probably want to diagnose what exactly is causing the drop first, rather than going over to Samsung. As a start, fully charge, leave it, when drop 30% report back what your battery usage menu says, and proly download betterbatterystats from xda forum to see what's using so much juice

Added on January 27, 2012, 11:43 amTruth be told, flashing kernal and thunderbolt are nice quick procedures, unlike say, flashing new rom from wipe and restoring ur shizo from titanium and what nots

So just be careful and follow instructions properly, and all should go well in just a few mins

Technically yes, AMOLED would be a lot more power efficient than S-LCD...

You lost 70% battery life overnight?

What was your phone doing overnight?

Wifi/3g on?
Email/accounts auto sync?
Too many active apps running?
GPS on?
Bluetooth?

Come post your screenshot.. as I can't believe it

Here got little problem...
Every time reboot my phone, those apps in my menu will rearrange to it order, i have to rearrange back it into my way...(even inside a folder, it will still come out from the folder) any solution for tis?

Weird isn't it, I only turn on my WiFi and Whatsapp. No more others. If I turn off Wifi, it will from from 100% to 60%. I'm charging my phone everyday!!!! aduh..... I will downlaod the batterystate as recommend by other forumer here to have a look.

Alot of people have told u its not normal. Alot of people have ask u to download betterbatterystats and check for wakelocks. So please do so instead of keep complaining here.

Post your battery usage screenshot..

I'm on miui ics the UI is white compare to cm9 all is black, I would say it so refreshing, all the theme is working so I change theme everyday

Always use BBS to check wakelocks before you go samsung and diao them Its technically your fault for installing faulty wake locking apps

Here you go.
