Doesn't really matter. 75% if the battery life was used up by the screen. Even with better CPU governing, you will get maybe 30ins to 1 hr more. Even iPad 3 has 3-4 he's shorter battery life with a bigger battery. It has 1200 math battery and last around 9 hrs. 5 hrs on 8000mah was expected.
OK, those of you guys who have rooted there tablets, have tried altering the build.prop? I would think that would be easier to get more apps available. Also, has anyone gone over and asked the guys at goo manager if they would help make a twrp recovery for this?
