Default Galaxy S2 Battery Life

Hello All!
Got my Galaxy S2 from amazon.uk and upgraded the firmware.
Having a huge problem with the battery life...
i tried all and still very far from satisfying needs.
currently at 57% of battery life after 3,5 hrs of use with power-save on at 70%, no sync, advanced task killer at auto-kill...
how to resolve this? factory reset? some app? new/spare battery????
Please help
thx!

It's a known bug. You will need to freeze the wifi sharing process with titanium backup or similar. It all requires root access to the phone.

Also.. get rid of that "advanced task killer" thing, it won't do you anything good.

Just freeze it, it has nothing to do with your wifi being on or off

Hi all,
I have the display problem on the galaxy S2! the display is eating up 70% of the battery! I'm on 3G, email synch every 15min., wifi off, GPS off.
This seems very strange, I checked the battery status graph, and I can see that the battery usage *dramatically* decreases when the phone display is on (phone is awake)
I'm getting 14~16 hours only please advice

I think I fixed my S2's battery life problems. I tried push charging once and it worked wonders! I charged my phone from the wall then after losing 10% I charged it from my PC USB. I then browsed the internet through wifi for about 10 minutes then charged it again through PC USB. Then voila! After 30mins. of playing music through the earphones, it lost only 5% power unlike before where it loses 15-20% in 10 mins of doing nothing but texting.

Oh, I also turned off my auto-rotate..

Hope this helps.
