Having gotten the Garmin 955 (non-solar) on September 9th and having charged it up to 100% for 3 times ever since, I have seen a decrease in Battery estimates from 34 days to 31 days after upgrading to sw 13.21. I tried restarting the watch, but it shows exactly the same. Power Manager is on max battery settings. Is anyone seeing this as well? I refuse to accept the fact that the battery has deteriorated/ lost 10% capacity, the watch is as new...
