We use the program, BatteryEater Pro, to determine the Inspiron 15R's battery runtimes. Diverse profiles, which simulate use during load or idle, are used. The Classic Test simulates the use during load. The Inspiron 15R achieves a runtime of 1 hour and 21 minutes in this test. The notebook reaches an impressive battery runtime of 8 hours and 8 minutes in the Reader's Test, which simulates idle mode with maximum energy saving options. If you'd like to watch a DVD on the go, the battery still lasts for 3 hours and 40 minutes. That should be enough for watching practically every movie to its end.
