Samsung battery test video shows the Galaxy S7 crush the competition, but we are not convinced
Do note that in the last half hour of testing, the Galaxy S7 and S7 edge's screens become very dim – almost "impossible to see"-dim. This lowers their energy demand, therefore boosting longevity. If Samsung had stopped the clock there, or kept the screens brighter, the Galaxy S7 would have scored about 9 hours and 30 minutes (10 hours and 15 minutes for the Galaxy S7 edge), according to our calculations.
For the sake of relevancy, our test keeps the units' screens on a constant average brightness setting for the duration of testing, which we believe is a more realistic approach. After all, the logic of typical use supposes that smartphone screens are kept reasonably bright throughout the day, and most of the evening.
Another possible discrepancy we'd like to point out in this test is that the screen brightness measurements shown in the follow-up documentary video by Samsung are carried out in a lit setting. These measurements are supposed to be taken in the dark to minimize the possibility of ambient light interfering with the test results. This is especially true in Samsung's case, as the company is using a lux meter to measure the luminance, which captures a lot of ambient light.
By the way, our battery test is championed by the BLU Studio Energy, a smartphone that appearеd in North America last year. It achieved an outstanding 14 hours and 53 minutes of constant simulated on-screen use, enabled by its large 5000mAh battery.
