The battery seems to drain as fast when the tablet is put to sleep and when it is in use with the screen at 100% !
I powered up the Nexus 7 at about 11am this morning and the battery was at 100% after a full nights charge. I used it to read for about an hour then shut the screen down. It was undisturbed until it about 10:30pm and the battery was completely dead would not even display the charging icon, let alone boot up for about 5 minutes after put on the charger?
Do I have a defective unit or is something not set right? It is still stock 4.1.1.
My Kindle Fire had amazing battery life when in sleep mode, like more than 24 hours.
