A:Answer Around 8 hours with heavy use. The newest Toshiba Chromebook 2 cpu is double the speed of the Acer (make sure its the model with a celeron 3215u) Better IPS screen, back light keypad, Micro SD slot, it is not as fancy looking as the Acer but is a superior machnie. Also if your willing to spend more money then the HP Chrome 13 is worth considering also.
