Apple Watch Series 8 battery drains (since WatchOS 11.6.1?) even though battery capacity still at 86%
Until like 3 weeks ago my Apple Watch (almost 3 years old) lasted almost all day (=24h). Now I can go to sleep fully charged and get up in the morning and battery sometimes is at 20 or less percent. Even had it switch off due to low battery. Similar behaviour during the day. - It pretty much makes my watch useless.
It roughly started after installing 11.6.1.
I have tried the usual things recommended here (like restart and even unpairing and disabling live-actvities and uninstalling most apps), but no improvement.
Do I really need to buy a new watch? So expensive!!!
Any thoughts very much appreciated !
side notes:
- one evening about a month back I had trouble with the accident alarm going off continuously. Couldn‘t stop it other then by turning off the watch … which was tough, as alarm was *continously* going off.
- when that happened, I had serious trouble using the touch screen. It just did not react.
- problem vanished without me doing anything.
- I have been using my watch for swimming for a while.
- Watch still reports 86% battery capacity (even with Apple Care+ this would not qualify for replacement)
