Overall, the Inspiron's battery life is satisfactory and on par with those of its Haswell precursor/sister model. The Inspiron manages a runtime of 5:30 hours, and is again surpassed by the Aspire (7:04 h). The wireless modules are disabled and the screen's brightness is set to approx. We test the video playback time by running the short movie Big Buck Bunny (H.264 encoding, 1920x1080 pixels) in a loop. Websites are opened automatically every 40 seconds using a screen brightness of approx. Again, the Aspire (6:52 h) defeats the Inspiron. The load runtime is measured with Battery Eater Classic tests using maximum screen brightness, the high performance profile, and enabled Wi-Fi modules.ĭell's laptop stopped our Wi-Fi test after 5:48 hours. The Inspiron shuts down after 1:17 hours of load the Aspire (2:52 h) runs over twice as long. The screen is set to minimum, the energy saving plan is enabled, and the wireless modules are off.
A rival, such as Acer's Aspire E5-571G (13:15 h), lasts considerably longer. Idle mode is ascertained using a Battery Eater Reader test. The Inspiron manages an idle runtime of 7:56 hours.
