How do e-ink cases affect the battery life of my Samsung device?

E-ink cases have a minimal impact on the battery life of your Samsung device. This is because e-ink technology consumes very little power. Unlike traditional LCD or OLED screens, which require constant power to maintain their display, e-ink screens only consume power when the image is refreshed.

When an e-ink case is not actively changing the displayed image, it essentially consumes no power. This means that using an e-ink case can help to extend your Samsung device's battery life, especially if you frequently use your phone outdoors or in low-light conditions where the screen brightness is turned up.
