Does resolution reduce battery?

[JerryLetehen]

Have researched that there's no difference between 1080 and 1440 in battery usage. A guy on YouTube tested it out but there's a hint: phone will use less power when enabling maximum power saving with lowest screen resolution.

Who to trust?

Trust me. The difference between 1080p and 1440p in battery usage is very low. It is only the refresh rate that can make a big difference in battery life. It's the processing power used for 1440p processing that uses more battery. The screen itself still works the same, so it doesn't make a difference. When it comes to the refresh rate, however, the screen itself is outputting more Hertz, which means more battery.
