ASUS ZENBOOK UX31E Ultrabook Review

Battery Life

We wanted to test out the battery on the Pantech Element, but we did so using our own methods. When we travel we use our tablet PC to watch movies. Most of the time when we are on a plane or stuck in a car on a road trip it is during the day and you have to crank up the screen brightness in order to be able to see anything. We set the battery mode to ‘balanced’ and increased the screen brightness to 100% and left Wi-Fi enabled. Some sites turn off Wi-Fi and lower the screen brightness, but we don’t feel that is something most people do in the real world.

We wanted to put a full length movie on our Ultrabook so we turned to Slysoft for a solution. We were able to use AnyDVD HD and CloneDVD mobile to ‘backup’ our store bought DVD movie on our laptop. For this review we used the movie ‘Something Borrowed‘.

We converted the movie from MPEG2 to MP4 at a video bitrate of ~2500 kbps. We then played the movie with the built-in player until each device shut down when the battery died.

We’ve tested several tablets with this same test, so we included them in the chart above just for fun. The ASUS Zenbook UX31E-DH52 lasted just under 4.5 hours when constantly playing a DVD quality movie! This is pretty solid battery life from the 50 Whrs battery in the Zenbook.
