Thanks for posting. The screen will need to stay on while running the full discharge Battery Benchmark. If you turn it off, the benchmark will end. There is the option to enable Dim Screen, which will dim the screen while the benchmark runs. This should help keep your phone cool. Either way, your phone should not overheat while running the benchmark.
Thanks for letting us know about that bug as well. Which version of Android and Geekbench 4 (e.g. 4.3.0) are you running?
I am running Android 6.0.1 and the latest Geekbench 4 on Google Play on P1
But still... What if the battery doesn't survive enough or the LCD IPS
screen gets a burn in? Still... I will do it anyway.
Thanks For The Reply have a nice day.
