I have Apple Watch series 3 from the end of 2017. I used my watch every day, but when covid hit, I stopped using it so often. I always put my watch on the charger and picked it up to use it only when I went out (rarely). Last update I did was 6.1.1
Coincidentally, a few weeks ago I put on my watch (fully charged) and shopped. I tried to use Apple Pay, but my watch was off … came home and charged it a bit, and it was back to 100% in minutes.
This kept happening, so I decided to unplug my watch and reset the power. Then reconnect the watch. Tried to do the update, but it went slowly, so I just let it update on the charger overnight, and now it does not turn on at all!
Is this a lost cause? What more can I try?
For further information, I never had the watch in the water and kept a tpu protector on it to avoid scratches.
