Same issue. I have a series 3 and could normally wear my phone all day no problem and have plenty of battery life left when I get off work. Now it seems like it gets to about 70% and completely dies. I make it to about noon and then it shuts off. I’ve never seen it get to 50% even. Very frustrating when I suddenly have no watch. I charge it and then it turns back on but the battery is far from dead so it’s like there’s something wrong with whatever triggers the phone to shut down due to low battery. They need to fix this ASAP. Not cool! I’m going to see if I can restore it to an earlier version of iOS until they get this fixed. Oh and I’m getting tired of having to reset my whole watch just to update it because they weren’t smart enough to give the v3 more memory. I can have all apps off and nothing else running and it still says there’s not enough space to update. But that’s a different problem for a different forum.

Advm301 I was getting very frustrated so I changed the Country on the watch and paired manually. I didn’t expect that to work but there’s a different screen now and it’s saying it’s downloading so THANK YOU! Weirdest fix EVER!
