Kernel is Synergy-Kernel-v0.10-CK3-OC-OTG-
Replaced the battery with a battery i got at batteries plus for $ 49.99
which is RAYOVAC : CEL11197 3.6V 3000 mAh 11WH Li-ion
The orignal Galaxy s2 battery is: 3.75v 1850 mAh Li-ion
Here is a picture showing the size difference
with the battery being double the size it comes with its own back cover
I had gotton 46 hr 30 min on 1 battery, with out charging. i been text,calling, on the web and every thing under the sun to put a load test on it.
Its really weird not charging the Galaxy S2 everyday
