Just tried this AnTutu v3.0.3 won't run 3D test complete, it gets to the troll and ninja and at same time every time just goes blank. Connect to mains and zero issues.
Quadrant runs on the battery no issue as does GTA Vice City and HD Video, makes me think it's a software/firmware issue.
I shall test more tablets at work with AnTutu on battery as I did all my benchmarking with tablets connected to mains to see if other models have the same issue.
But for games and HD video I've had no issues and the battery is now giving me a good 5-6hrs of heavy usage now I've had it a weekish
