watchos 10 charging issues

Confirmed.. deleted MobyFace and my watch works again.

The latest update watchOS10.1.1 and also doing a factory reset as a new device (not doing backup) has fixed mi issue for now.

I have the exact same issue. Apple watch 8, no issues until updated to wos10 last evening, since then, no charge or poor charge.

Also when it does charge it is slow. tried 3 known good charges with same results, older apple watch charges fine on the same chargers.

Same issue here. Watch gets very hot and charges slowly while also draining more quickly. I have been charging my Series 5 watch with the same charger for years and it is awfully suspicious how this occurred the day I updated to ios 10. While over the years I have experienced expected diminishing performance, this is an incredibly disappointing update. Luckily they just came up with ios 10.0.1 so hopefully this will fix this issue.

Finally after two weeks went to the Apple Genius Bar and they tested the watch, Apple Watch Ultra..Battery was fine and nothing else popped up in diagnostics. They took my watch and sending it for factory reset or they will replace it. I will know what the outcome is in a few days. But they did not know of anything yet.

Since so many of us are having this problem and it’s most likely software, I recommend making a formal case and taking it in. Maybe Apple will address it sooner. Our watches were completely useless because they drained so quickly.

Update. Apple Watch 7. Didn't have MobyFace, but removed ALL other non-native apps. Usually the Watch still won't fully charge, apparently overheating and then stopping charging due to the heat. Yet, sometimes it charges. Can't decipher why. If I do a power cycle it will usually fully charge after that.

Figured it out. With the new update, once on charger you need to tap the small charging icon, and it will say "charging to full". That will cause it to charge to full.

Remove MobyFace from the watch. I bet you have that don’t you? Try it.

I removed a bunch of apps and the Moby Face, that was the trick!! Thanks to everyone that posted!!

Removing Mobyface worked for mine. Watch charged all the way to 100% and is currently working as expected.

Did you have MobyFace and remove it? Try that….

Yes, I need to restart by Apple Watch just about every time I need to charge it. Also, os10 resets the battery default to optimized battery charging which only charges the battery to 80%. This can be switched off in settings/battery health.

So my wife’s watch series 8 has this same issue, just recently updated to watchOS 10 and suddenly her multi-charging stand won’t charge it. The charger was working fine up until the update clearly screwed something up. Charger Still works fine with my old series 3 watch, and watch charges with other chargers. There’s no doubt whatsoever this update broke something with charging.

However, turning off battery optimization/optimized charging did not fix it. Hopefully Apple patches this.

Watch series 7 user here. My watch usually lasts 20-24 hours on one charge. Today, charged it to about 100% ... and then updated to WatchOS 10.1. Was very surprised 3 hours later to see a low battery alert. What?

The drain under the red line (curve) is normal. The area under yellow is far from normal.

Got home, put it on the charger, and it went from 9% to 41% in an hour ... and then, from there, WHILE CHARGING (using original Apple charger), it DROPPED to 35%.

Possible good news: I did a hard restart, and within 12 minutes or so, it went from 35% to 56%. Fingers crossed that's all it needed.

My ultra went from the battery lasting almost 3 days to now lasting only 5 hours. It’s also been slow to charge and has been getting really hot while on the charger. My usage on the watch has not changed. Only thing that has changed was the update and the update has made my watch useless!
