So I have a problem with my new apple watch. I upgraded my watch from series 1 to series 3, and the battery charger has been insane. Yesterday I had almost 240% battery usage with only 6 hours of screen time when I earlier this week would have spent just over 100% battery use with around 7 or 8 hours of use. I even put it in flight mode for 3.5 hours and my battery went from 100% to 70% which is insane. Does anyone know what makes the battery so much? My battery life is 92%, so that's not it. I'm just annoyed that my battery lasts literally for 3 hours.
