- qwerty456127 8y agoIf this is true, it's a design mistake. Backlight should never be paired, it should be activated on demand either by a button or by an ambiance light sensor. Having backlight turned on when reading a book on an e-ink screen during a day is a ridiculous waste of battery unless you hide in a closet.
