OnePlus 6T vs iPhone XR / XS vs Mate 20 Pro vs Note 9 Battery Life DRAIN TEST

Finished last at 5 hours 1 minute, well short of Apple's claims, though he suspects equal-brightness testing is part of the reason.

Very well optimised, lasting 6 hours 47 and keeping OnePlus's reputation for good battery life for its capacity.

Lasted longest at 7 hours 44, the best battery he has seen on a mainline flagship, though not in a different league from the Note 9 or XS Max.

Pushes the most pixels over the largest area yet still lasted about 6 hours 56, helped by the efficient iOS 12 and A12 Bionic.

Lasted 7 hours 7 minutes at 1080p, but at its maximum resolution the iPhone XS Max tends to outlast it.
