The notebook’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)

Well, the 6-cell battery confirms the mobile positioning of the U1F despite spoiling its appearance somewhat: the notebook lasted as long as 3.5 hours in the Reader’s mode. You can imagine how long the battery life is going to be with the max-capacity 9-cell battery!

Here are battery discharge diagrams for the different test modes:
