So my Watch was on the OS 2 GM for the past few weeks. Today I got a 12.5 software update that I assume was to patch the critical bug that delayed the OS 2 release to the public. I never have less than 40% battery left when I go to be (between 11pm-12am est). However, after updating there seems to be something causing massive battery drain as I got an alert that I was down to 10% at 7:55pm and by 8pm I was down to 6%. Anyone else experiencing the same problem and if you are do you have a fix?
