Love this tablet when its functional. However it will randomly reboot. Sometimes when I think its "asleep" its actually depleting the battery completely and a rapid pace. When its plugged in, it will often shutoff. Meaning you pick it up to use it and have to wait for it to boot. Fast when its working but not impressed with sleep/powermanagement/battery at all. I am aware that I should expect rapid battery loss if I am playing some high end game. However when asleep and no games running, it should last overnight on a full charge.
