4 hours of usage and only 2% left? Wow, S2 battery sure does drain very fast.

By the way, did you surf the web? If you did, you use Data or WiFi?

just use data connection when needed only. please don't compare with BB battery with data on 24 hours

Hmm, honestly is it the applications or the display that's consuming most of the battery?

Hahaha didn't compare with BB lah. I'm comparing with my Galaxy W. My brother use Galaxy S2 also battery can't last more than 7 hours. I thought it was his only. Looks like most of you on this thread also same problem.

its not a problem.like anttoo said, its a feature. and i'm not bothered with the battery drain any more. the best way to make it last longer:

quick and dirty guide to have less battery drain:

- use 2G-only if you don't need 3G
- monitor programs which cause wake-lock. use betterbatterystats and either uninstall or tweak them
- do not use task killers. see the previous item and find the malicious programs instead of repeatedly killing them.
- do not activate google latitude on maps.
- if you don't need pushmail, uncheck gmail sync and use k-9 mail to pull mail, lets say, every 1 hour or so.
- go to settings / location and security. disable "use wireless networks" and "use gps satellites". enable them when you need them, other than that keep them disabled.
- disabling auto-brightness and using a low brightness level helps. do you know that you can adjust the brightness by swiping your finger across the notification bar? try it...
- using juicedefender may help, but it may also cause more drain. test it yourself.
- if you need more speed than 2.5G (i.e. edge) disable HSDPA (*#301279#, select 2 then select 1). you will have 3G instead of H(SDPA) and I think it is fast enough
- disable fast dormancy. dial *#9900# and disable.
- disable auto sign in for google talk (search for talk in appdrawer and use settings to disable automatic sign in)
- disable samsung update and don't use samsung gadgets if you are not in love with them. (this part may be taken care of the rom developers)
- try several radios. I recommend you to try KE7, KG2 and KH3 and choose the one which suits you best. KG2 seems to be the best for me. however, in terms of battery life, there is not much difference between those three.
- be aware that more you use your phone more the battery drains don't complain like "my battery drains quite fast but I did not use my phone. I only played angry birds for hours without making a single call" or don't expect to have a decent battery life if you use your phone as a computer or download torrents using your phone.

anttoo, do we need to reflash the tB tweak after we flash a new kernel?
