The UMPC’s battery life was measured with Battery Eater Pro 2.60. The test was performed at the maximum screen brightness in the following modes:

• Classic (the system bears the maximum and evenly distributed load)
• Reader’s test (the pages are scrolled through each 15 seconds)
• DVD mode (a DVD movie is launched in Battery Eater’s Idle test mode)

It is a surprise really. The weak hardware configuration swallows the whole battery charge too fast. The hour and a half in the Reader’s mode is too short for a computer that it designed for travels, i.e. for being used away from a constant power source.

Here are the battery discharge diagrams for the different operation modes.
