> uses more power so kills battery life faster not necessarily. on promotion iPhones (fancy name for variable refresh rates), the panel is not stuck at 120Hz all the time. it varies from 1Hz when the screen is static up to 120Hz when it's getting animated, down to whatever framerate your content is at (e.g. movies and videos). it actually is a battery saver whenever the phone's screen is static (common on most apps with text) or with <60Hz content (youtube, movies, etc).
