Question

what device cutout save battery

Answer 1

Device cutouts, such as a notch or a hole-punch display, do not directly save battery. The purpose of these cutouts is to maximize the screen-to-body ratio by housing the front-facing camera and other sensors in a small space. This allows for a larger display area without significantly increasing the overall size of the device. The battery life of a device is primarily dependent on factors like the battery capacity, display brightness, background processes, and software optimization. However, since cutouts reduce or eliminate the need for bezels, it may indirectly contribute to power efficiency by reducing the overall power consumption of the display.
