From a full charge at about 10pm at night I’d wake up at 85-90% at 5am the next morning. Today from 100% I woke up with 40% at about 7am. Doesn’t last the whole day (no activity) it was fine with 17.1.1. Watch is on WatchOS 10.1.1
Ugh, I updated to 17.2.1 yesterday and noticed at end of day my Series 8 was at 19%. Normally it’s more like 50%. I thought it was a fluke until I found this thread.
So glad i left my watch on iOS 9…
Same thing happened with mine. I thought I was just imagining things but I feel so validated now.
Just you.
Do stop updating your device, that is my advice
Yes, this is happening to mine.
Yep same. Battery already at 55% on my ultra 2 after a single day. Previously it used to stay up around 85-95%. I was not having this bug on previous watchOS after updating to 10.1.1 it went downhill for me.
Took it off the charger and went to work last night and it was dead about 4 hours later. My battery capacity is 90% and usually lasts a full day, I’ve never had battery drain this bad before.
Series 5 watchOS 10.1.1
I’ve been rejecting the latest update for the past few weeks. Every time I think maybe I’ll update, someone posts about battery drain with a later version. This is ridiculous.
Yes. I installed Beta iOS and it’s been working great now.
Strange. I’m getting around 36% the second day after 24hrs. I also didn’t get a watchOS update. I’m currently at 10.1.1, Only my iPhone got the 17.1.2
Same I’m charging it twice a day . I have a series 8
No problem here
Prior to WOS10 my AWU would last 5-6 days (lots of background running apps disabled, WiFi and cell off unless needed, AOD off, no info watch face, many other settings adjusted to achieve this). Since 10 update best usage is 3.5 days but often shorter. All setting remain the same but it just doesn’t last like before. Battery health is 99% charge watch and phone on Apple brand dual usb 35w charger with both their brand of braided cables. I get why my 12 pro battery only last a day at best and that leading me to eye that 15pro. Shouldn’t be the case with my AWU1 to the AWU2.
Don’t you mean watchOS 10.1.1 ? Which is the latest iteration of the OS on the watch.
