Battery life in the Blink Indoor is billed at “up to two years.” Keep in mind, though, that this depends on the frequency of activity in the frame and how you’ve programmed your motion detection settings. For example, if you’ve set the camera at a lower or fluid image resolution, your battery will last longer than if you use the “best” setting at all times. It’s all in the settings, but generally, the batteries in a Blink camera go pretty far.
