Battery Life For Games, Presentations And DVD Playback
THG calculates the operating life of the battery using three typical, everyday applications:
DVD playback: A DVD video (Apollo 13) is played and replayed until the battery has run out. Presentation: A presentation runs in a continuous loop until the juice is gone. Game: In this case, the 32001DMark 2001SE demo is the basis for the test.We chose the "Portable/ Laptop" setting for all three tests.
While the Lifebook S2010 with the low-voltage Athlon XP M CPU runs for a good two and three-quarters of an hour, the Lifebook S6120 comes in at just under three hours (presentation).
In the DVD test, the Lifebook S2010 suddenly falls well behind. However, this is attributable not to poor power management by the CPU, but, above all, to the DVD player software used (Power DVD), which, at 40 percent, has a relatively high average processor load. With the Lifebook S6120, the average CPU load in DVD playback was just 25 percent. If the processor load remains consistent at almost 100 percent (game), the lights on both notebooks will go out after just over an hour.
