Apple Watch battery drains after updating to watchOS 10.1

I uninstalled the Moby Fox app yesterday. Put my watch on at 2:00 AM. It is now 11:00 AM and I have 34% battery remaining.

Do you happen to have an app called MobyFace? If so delete it. It will and should resolve the issue. Did for me!!

UPDATE: I deleted MobyFox app almost 1 hour ago and my Ultra is still sitting at 100%. This may appear to be a fix by removing a 3rd party app like this. I suggest others to try this as it seems to be working so far. Just FYI I did not reboot. My brightness is at full and watch face is always on. I will update again due course!!

I have updated to 10.1.1 and my battery is still draining in 2 to 3 hours!! How do I fix this, it so frustrating to have such an expensive watch and I can't even wear it. It also take forever to charge because the battery gets so hot that it stops charging

It's time to have the watch evaluated by Apple:

Hey @Jeff Donald - trust me when I say that none of this works. I had done all of the above which also included returning to the Apple Store for them to send away. The only “seen” way to resolve the battery drain issue is to simply remove a third party app called “MobyFace”. If you don’t have this app then I am not sure your next steps. Good luck to those who are impacted. This removal of MobyFace resolved the issue for me!

Even more so. My Ultra (first gen) usually gets 2-2.5 days per charge. I updated to WatchOS 10.1 yesterday and it went from 80% to 10% in about four hours. A few reboots and a charge to 100%, I went to bed at 10pm. At 4:00am, I was at 7%. I have it in the charger now, hanging in front of a blowing fan to keep it cool and trying to get it up to 100% without overheating.

the oddest thing is that when I check the battery in the settings, these charge and discharge cycles are blank. As if the watch was off the whole time, with just a handful of green bars in the 70-80% range, then blank for several hours.

I’m very tempted to wear my old Garmin watch until the next WatchOS update. At least it will tell the time and last a few days between charges.

Update: After changing just the location in the weather to a fixed city, the drain slowed, but in 3 hours I still used 63% of my battery life. I will be forced to attempt to disable all location services now and see if that helps. This is NOT acceptable by any stretch of the imagination.

So deleting MobyFox seemed to work but then the same night my weather app deleted itself and it only reinstalled with the latest iOS update. It is better but not what it once was. I do get almost as long as I used to.

Had an appointment last Friday at Apple Store to address this issue. My watch would charge overnight to 100% and when I put it on in the morning it was dead within a few hours. They sent it in as I still have apple care. It was returned yesterday with a note stating they reinstalled the operating system and that I should set up as a new watch. I did and put it on and it was dead in an hour. I didn’t check the battery status at the time. I charged it overnight and put it on this morning and started noticing battery rapidly dying - Dead in three hours. I even turned off a lot in app refresh - 🤨 they obviously screwed up with the last update… now what?

Overheating has frequently been reported. Maybe overheating damaged your watch and battery. Contact an actual Apple Support channel to see what the next step is. There are too many trolls making snide and condescending remarks on these community forums to help with your new problem.

10.1.1 has fixed the battery drain for our Apple Watches

Hey Jeff_888,

I acknowledge the detailed instructions provided and the structured approach towards conserving battery life. However, from a healthcare perspective, I find some of these suggestions may compromise the essence and utility of the Apple Watch, particularly in monitoring vital health metrics.

The recommendation to disable the heart rate sensor, for instance, diminishes a critical feature that provides real-time feedback on an individual’s cardiovascular health. Similarly, the advice to limit cellular and Wi-Fi connections, or to resort to Low Power Mode, may hamper the timely relay of health notifications and other crucial alerts, which can be of paramount importance, especially in emergency or critical situations.

In light of the integral role that real-time health monitoring plays in today’s healthcare landscape, it’s imperative to find a balance between battery conservation and preserving the core functionalities of the Apple Watch.

It would be beneficial to delve into the root causes of the escalated battery drain following the update, aiming for optimizations in the watchOS that uphold battery efficiency without necessitating the deactivation of key health monitoring features.

Additionally how is this going to affect long term battery health? I am fearful that this will cause a significant loss of battery health/life rapidly.

Thanks for the attempt to prevent draining the battery but let’s get a real fix.

Rapidly drained,

Eric RN

Mine is the same. Last years model- series 8 maybe? Before updating to 10.1, even with workouts and AOD, I only had to charge about once every 24-30 hours. Since updating yesterday morning to 10.1, I have charged my watch about 8 times, it's taking considerably longer to charge than I actually get to wear it, and I only use the fast charger. It lasts maybe 3-4 hours and then has to charge for about 2. This is ridiculous. Is there a way to downgrade the OS version because I'd love to do that.

I’ve been watching battery life since the previous iOS tanked my series 5, since updating to 10.1 yesterday and after rebooting both watch and iPhone I have noticed my watch actually lasts longer…..got up today at 10am and put the watch on, used normal 3rd party apps during the day and it’s now 1am and it’s sat at 20% - all this with a battery health that states 79% recommend service is fine for me…..

I've noticed the exact same thing. I thought that maybe the watch just wasn't charging to 100% or there was an issue with my charger. I've bought a new charger and charging brick thinking it was an issue with the charging hardware. I've ran through all of the troubleshooting - wipe, restore and setting it back up with the same issue - lasting less than 8 hours. My watch face is always off - which is a setting that I have used since my Series 0, and the display is off after 60 seconds. I will try uninstalling the Moby Face app that was mentioned in this thread. I have reached out to Apple for a support case and will see what they say as or the next course of action. I wish there was an easy way to roll the AppleWatch back to a previous WatchOS as I would roll mine back to WatchOS 10.0.
