I have a 44mm Series 4 AW LTE+GPS that I purchased from ATT on a next plan and received it launch day. Yesterday around noon my watch died. I thought that maybe the charger had come unplugged and I just connected it to the magnet. I made sure to check it this morning when I woke up and it was 100% around 5:00AM. Around noon I got another low power notification. I haven’t changed any settings and do not have LTE mode currently on. The only difference in the past 2 days is updating my phone to iOS 12.3. Anyone else had issues since updating? Should I call ATT or Apple if it is hardware related and needs replaced?
