If the screen is displaying the same thing (think an “always on display”) then why does lowering the refresh rate help with battery if the pixels are still lit?
In: 0
Because refreshing the screen means the device has to calculate what shall be rendered and where on the screen, and then actually render it.
So imagine repeating this job 100+ times every second, it will require a lot of energy compared to if it only refreshed say 30 times a second
