Do phone displays really save energy when displaying more black pixels? I always thought that's not the case because the backlight is always on for the entire display anyway.
- lucian1900 7y agoIt has some effect for OLEDs, in which there is no backlight and dark pixels are simply off.
- kevingadd 7y agoYeah, this is the quirk exploited by features on some phones like "always on display" to be remotely viable battery-wise. They still eat into your battery but because the screen is mostly black and the on-screen elements are dim + infrequently updated, you can leave it enabled and be OK.
