OnePlus 7 vs 7 Pro / Zenfone 6 / Pixel 3a XL / Mi 9 Battery Life DRAIN Test.

Excellent battery life in a league of its own against most rivals, but beaten by the Pixel 3a XL despite its huge 5,000mAh cell.

Lasted half an hour longer than the 7 Pro, which makes choosing between the two less simple.

The 90Hz display noticeably hurts battery life, though he sees it as a fair trade-off for the smooth screen.

Lasted the shortest at 5 hours 47 minutes, but he was happy with that given its small battery and slim body.

Won the test with a record 8 hours despite a modest battery, thanks to its mid-range chip and smaller display.
