If you get a solution, PLEASE share it. I've got the Active watch2 , have all the apps turned off except calls and contacts. I turned the "always on" off. Display is set to 4 for brightness .... and at the MOST, with all these apps off, my watch will just make 12 hrs, then the battery is completely drained. ..... without even making a call. Very frustrating. Note: When talking with a customer service ... no matter what they say for a fix ... DO NOT DELETE your plan. After being on the phone for over 4 hrs, the rep told me to start fresh with the watch, delete everything (including the plan) and start all over with pairing, etc. What a nightmare! My billing was totally goofed up, I was being charged for a 2nd watch when resuming my plan.
Thank you for your reply ... no I do not have Strava on my watch. I uninstalled Spotify, and have everything else closed. Wow, if you can get 2-3 on your Active Watch2, that is amazing. I would love to be able to use the heart monitor, or even how many steps I've taken .... but those are ALL off to try and save battery.
