The EliteBook achieves a runtime of 18:23 h in idle mode. Competitors such as the Toshiba Portégé Z20t-B-10C (26:56 h) last significantly longer. The idle mode is tested with the Battery Eater Reader's Test: The screen is set to the lowest brightness level, the energy-saving profile is activated and all radio modules are disabled. Under load the EliteBook shuts down after 1:53 h. Once again the Portégé (5:48) is much more durable. The runtime under load is assessed with the Battery Eater Classic Test: The screen is set to maximum brightness and the high-performance profile as well as all radio modules are activated.

The HP convertible terminates our practically oriented WLAN test after 8:19 h. Once more the Z20t-B (12:40 h) shows a better performance. During this test websites are automatically called up in 40-second intervals. The profile "Balanced" is activated and the display's brightness is around 150 cd/m2. We measure video playback by running the short film Big Buck Bunny (H.264 coding, 1920x1080 pixels) in a continuous loop. The radio modules are deactivated and the brightness set to around 150 cd/m2. The EliteBook achieved a runtime of 7:08 h. The Portégé (13:07 h) lasts longer.

After all, the EliteBook 810 Revolve G3 shows very good battery runtimes. The Broadwell processor allows significant runtime improvements in comparison to its sister and predecessor models. For instance, it lasts about 2 hours longer than the Haswell EliteBook in the WLAN test. It is no surprise that the Broadwell EliteBook cannot compete with the Portégé. On the one hand, the latter is equipped with a very frugal (and significantly less powerful) Core M processor and on the other hand it has a bigger battery capacity at its disposal (Toshiba: 72 Wh, HP: 44 Wh).
