Maybe if you die in your sleep?

I don’t know what I did, I’m sure something was I reset up the watch as new 2 times. I forced restarted so many times… bitched to Apple via support 4 times… This morning I uninstalled all apps ( ok left peloton and a running pace app.) Turned off everything Music / photo sync disabled…. Somehow the battery life on my watch returned today… Ultra watch - 8:30am 100% - 10pm 73%

Doesn’t work for everyone, I have tried it 3 times
