Battery life is important for ultrabooks, which are meant to go wherever you do. We run two battery tests to give you an idea of how long the ultrabook is likely to last. As always, keep in mind that the way you use the ultrabook will play a big role in its battery life. Watching videos, downloading files, or putting the ultrabook in sleep mode while you take a break will all impact the time your system can run on a single charge. In both tests, we turn the screen brightness to 50% and disabled all screen savers and sleep settings.

|Light and Heavy Duty Workloads
Our light-duty Web Browsing test gives the Asus Zenbook Prime UX32VD a chance to show how long it can handle simple Web surfing. The test refreshes every three minutes and runs until the battery is completely depleted. We also use Battery Eater Pro, which runs a heavy workload continuously to show you what the system can do when its CPU, GPU, memory, and storage drive are seeing heavy use. If you plan to use the ultrabook to work with multimedia (or even to do a lot of word processing) the results will give you a picture of what to expect.
The UX32VD struggled in our battery life tests, at least in terms of the worst-case test condition with Battery Eater. In our light-duty Web Browsing test, the system ran for 286 minutes (4 hours, 46 minutes). That’s one of the shorter runs we’ve seen in this test, though we have fewer system to compare it to than we do for the Battery Eater test. As for Battery Eater, the stress test also presented a challenge. It clocked in at 108 minutes, making for one of the shortest runs among system we’ve recently tested.
