this is my battery life using 2000mAH right now:

they should send you the message when you buy your phone O_____O

You used the official Samsung battery or third party ones ?
I've came across some reasonably cheap 2000mAh batteries for around RM60 and I'm not sure about it.

So do i. I bought mine from digi. Its been a week.

wah your battery sibeh geng, 2 days 16 hours

i did try check rom..but when install app from kitchen, causing my phone to bootloop..so back to batista..i saw checkrom more to stock right..and also still using TW 4.0..im used to tw 4.5 already

hye guys... my friends going to buy new phone.. but he clueless between sgs2 n nokia n9.. any suggestion??

i'm a moderate user only meh. at least it proves that SGS2 can have a long standby time. after this want to try achieve at least 4-5 hours of screen on time.

what app you installed? no problem for me wor.. only when i try first time the server slow then wait damn long

never try batista so no clue which better.. batista also based on stock i thought?

Go launcher > TW huhuhu

are you talking about andida battery?..OEM samsung 2000mah battery is RM139..andida around RM30 like that..but not really 2000mah as stated..

Receipt of what?

CM sau pei edi after i tried checkrom lol.. guess i'm not loyal afterall
what's good compare to CM7:
- much better battery life
- support tvout
- support ntfs thumb drive (though still buggy and require manual work)
- my favourite feature in CM7, the notification toggle bars is in checkrom too, though cannot reorder the toggles
- customizable extended power menus (choose from a bunch of options)
- better stock video player
- easily mod the camera to support volumn button shutter and low battery camera hack, the CM7 camera looks ugly also and video recording less smooth
- SMOOTH in everything
- default sms app still better, with sms notification appear in screen that you can 'slide to open sms'
- can use any kernels unlike CM7
- many useful mods in kitchen dont need to search in between forums and forums
- arcade emulator (tiger arcade in particular) runs smoother compare to CM7

what i miss in CM7:
- the ring lock screen
- able to stop app via long-press back button
- permissiosn management that can block any app from accessing certain permission built in (don't need seperate app) i think this is the best feature i miss from CM7
- swipe away notifications

overall, pros more than cons combine checkrom with go launcher (best launcher evarrrr) is a perfect match!
So far no encounter wakelocks yet.. will update you after further monitoring

I can barely last 2 days with 1650mah battery, at the end i left 10%. screen on time only about 2-3 hours is that good?

did you install directly after download it thru kitchen? What i did before was install any app from kitchen thru recovery mode manually. everything is ok for me.

i install directly thru kitchen wor, but i'm on 3.1.1 la... kitchen new version too so maybe something is fixed?

agree on installing manually through recovery much safer though

you are using data connection also right? that should be good enough i think. as long as you can get that kind of screen on time, 2-3 hours is good. the best i've heard from xda was 6 hours..
