While watching Netflix with wifi, I get 4 hours battery life at best on lowest brightness. Battery usage is 65% screen, 10% android system, 7% mediaserver and etc. I once left the Nexus 7 on standby for a few hours and it dropped 2% of the battery.
Since my wall charger has been unavailable to me, I have had to charge the device with a usb cable to my computer. Could this be the reason for the poor battery life? Or is this kind of battery life typical?
