Hi, just a tip in case someone else is having the same issue. I had problems with battery drain on 20.32, with the watch lasting 6 days instead of 9 and my phone also no longer making it to the end of the day. On the phone, Connect was shown as the most active power user and if I opened the Connect App, I often saw that it was "sending update" even though I already was on 20.32.
This was annoying me for a week or 3 but then I forced the watch to check for updates today and it turns out there IS an update...a timezone update. After forcing the install of that one the battery life seems more normal again.
So for Garmin: there's a bug where you keep sending updates over BT even if the files are already on the watch.
