I've been enjoying watchOS 2 but last night my battery was down to 7% and so I flipped it into power reserve mode. Before bed I attached it to the charger and this morning when I put it on it wouldn't boot up. Seems like it thought it was still on the charger too. Tried rebooting a few times, then tried hard reboot, nothing works. Before going to the Apple store, am I missing something guys?
