So I always had my watch auto defect workouts.. well with my watch 9 it's draining the battery super quick (like 60% in 6 hours) my watch 8 never drained that fast. Is anyone noticing a draining when auto detecting workouts?

      Hi musicismylife29 🙂
      Congrats on the new watch 9! First and foremost are you running bluetooth or LTE and how long have you been using the new watch thus far?

      Thanks for the update 😊 and hmm something seems a bit off. You should be getting better battery life. Is the drain still as harsh now after full optimization cycle? That should generally be about 5-7 days after unboxing. Also did you port over a watch back up when you got the watch 9 or did you start out fresh?

      Yes the battery on mine is also draining super fast. I lost 35% overnight while sleeping. Never had this issue with my Watch 7.

      My watch 9 barely lasts 24 hours. Definitely not happy with battery life

      My watch 9 (44mm BT) battery sucks!
      I have to charge it every day!  I charged it yesterday afternoon and lost 60% when I woke up!

      My Galaxy 6 didnt do that.

      The first 2 weeks I had my Watch 9 40mm Bluetooth version, the battery life was great. This past 4 days the battery has drained faster and faster every day. Cannot get 10 hours out of it now. I turned off heart sensor, uninstalled some apps, and it was worse. My Watch 8 used to last 2 days. Im so mad I traded in my Watch 8 before this started. Now they tell me I cant have it back and I just lose it if I return the Watch 9.

      I've had the Watch 9 since 8/7 & the battery is horrendous! It doesn't even last a full day. I'm so mad I can't trade it in & get another Watch 8. I only run Bluetooth on it & use it to detect workouts so there's no reason the battery can't last a full day. I could go nearly 3 days before having to charge my Watch 8. The 9 was supposed to be an improvement but it's been nothing but a headache.
