Battery from 100 to 3%,
just for fun.
What looks stupid is that connecting to a computer (USB, to transfer books) for 1 minute brought battery from 100% to 65%. This happened right after disconnection.
Also, going from 50% to 3% was very abrupt. The device was used yes, but it wasn't watching videos or anything...
Otherwise, while screen is off, things look good I think
Anyway
I'm not complaining yet. Once I fix my TS problem I can gain root and start analyzing battery. I think this is fixable easier than the TS.
