My Fenix 5 plus updated to firmware 4.00 in the morning. I can't find the changelog yet. (GPS, WIFI, Sensor Hub have same ver. as 3.56 Beta) ciq.forums.garmin.com/.../1387081.jpg
I tested it last Sunday. After a 2h run it took another 10% battery within the following 2-3h. So I'll go on with my "reboot after activity" procedure. I've to charge two times/week now. I was used to once a week with my 935 before (still at 40% when recharging). Anyway I somewhat got used to it. As long as it has enough battery to cover my single activities I don't want to complain too much.
I wasn't happy with 4.2 swim. Reported to the beta team. Turned off Auto Update. Rolled back to 3.1 It's just updated to 4.2 again on it's own! For anyone rolling back, be aware you need to turn auto updated off after the roll back! Pretty obvious with hindsight! Swimming tonight - do I test it - or roll it back again?!
