If that's not the result you're looking for and the test is simply to see which battery lasts longer, then a radio-free test environment is ideal.
Thanks for your comments!
So the best way would be to run several tests, probably as following:
1) test video playback time till 0%
2) regular test with radio and screen on/off (found app for that https://play.google.com/store/apps/d...attery.utility
- the problem with it it stops at 15% charge. I want an app which goes down till device turns off - some batteries have been reported to work long time on 1% left due to not correct display of charge% left on the phone). I am also looking for other apps to run such mixed test.
3) test wifi file transfer time. - select a file and run download and upload till the battery goes off.
Any other recommendations please?
