ThinkPad T470s Benchmarks: Battery tests

Page 5: ThinkPad T470s Benchmarks: Battery tests

In the following benchmarks we employ two very different battery life tests: Battery Eater Pro and a custom 1080p HD video loop test, to prove out battery life with our test group of machines. In all tests, Windows 10 Quiet Hours have been enabled and displays are calibrated with lux meters on pure white screens to as close to 115 lux as possible. For the average notebook this is somewhere between a 45 - 60% brightness setting. Since notebook displays significantly affect power consumption and battery life, it's important to ensure a level playing field with respect to brightness of the display for battery testing. However, since many notebook displays vary in brightness at each respective brightness setting in Windows, this calibration with the meter is also critical to ensure all displays are set to as near identical brightness as possible before testing.

Battery Life

Heavy and Light Loads

Battery Eater Pro wears systems down quickly with a heavy load on all subsystems, including processor, graphics, memory and even storage. This is a worst-case test that will give you a sense of how a machine will hold up under heavy strain, when gaming or under heavy-duty continuous content creation workloads, for example.

The Lenovo ThinkPad T470s has a 49 Whr battery on board and combined with its non-touch 1080p display on the model we tested, it has solid endurance. It scored near the top in both battery tests. In our video loop test, the machine lasted over 7 hours in fact, in continuous use.
