Hello. I went to sleep wearing the watch with a full charge, woke up and it’s 10%, and continued to drain to zero over the next 45%. I had do not disturb and theater mode on, but it was on WiFi. That’s how I normally set it at night and it usually goes down 5% or a little more give or take. Anyone else experience occasional drains like this? I’m running a marathon in 2.5 weeks and plan to use it for the run, but will be quite upset if that happens the night before (so I’ll probably just leave on the charger that night!).
