Apple Watch Ultra battery draining while on charge after updating to OS 10.1

Exactly the same thing happened to me. They said they couldn’t duplicate the issue. I received my watch and when I paired it to my iPhone I noticed that the WatchOS was on version 10.0.1 instead of 10.1. I turned off the automatic updates and the watch worked perfectly like it did before I updated it. Funny that they didn't diagnose with 10.1 which seems to be the issue.

Same issue, watch was working fine until the latest software update. Battery is draining quickly even on low battery mode which is insane. My watch use to last 2 days without a battery and now it last about 5 hours on low battery mode. I end my work day with about 4% battery and totally disappointed at the $800 watch which i was so happy about before.

Thank all for sharing. I’ve been having the same issues the past few weeks with my Ultra. I thought, or hoped, it would resolve itself once I upgraded to the 15 pro max, but it hasn’t. An update is needed to fix this issue asap. I can’t use my watch for more than 3 hours before it dies. It’s nothing like the 36 hours or so I used to get from it per charge.

oh i was on the phone with apple support. He literally asked me. How long do i expect my battery to last on my watch. I told him longer than 45 minutes. Of course he had snide remark but glad its out there now.

because my watch is render useless at the current moment

so hope this helps you guys out, so what I did was I myself was on the phone with Apple, which was unsuccessful and irritating so I decided to unpaired my ultra and reset and the reset did the trick for the last two days I’ve left the Watch off the charger and the battery has lasted. There is an update that is coming soon. The battery has lasted so far without any drain. There is an update that is coming soon to help with this but I am on 10.1.

I have upgraded to the latest version of Watch OS (10.1.1) after this Watch battery fiasco with hopes that it would resolve the battery drain issue a lot of us have experienced. There is good news & bad news!

The good news is that it has helped somewhat lengthen the time between needing charging.

The bad news is that my charge still only lasts about 14 hrs. before having to recharge it. Not even a full day! Prior to the upgrade to 10.1 it would last close to a full day. So Apple has not really restored the battery to where it was before this problem began. I can only believe this problem that happened after the upgrade, caused the battery to be damaged.

This is not ok!😤

I have apple watch ultra 1 , used to get 48 hours of regular use from the battery ,and now after os update to os 10.1 and 10.2 battery dies after several hours, the watch was bought 10months ago ..

what can i do to go back to os before the last 2 updated, this is not what one expects from an Apple product

If you upgrade to 10.2 and the battery is still causing a problem, you need to leave it on the charger for a long time to fully undo whatever they did to make you put it on the charger in the first place. Mine started draining FASTER after going to 10.2, but then after about 48 hours on the charger it's back to normal now.

Thank you arsonist, for kind of putting out the fire.

The same thing happened to me after sending my new ultra 2 in for the battery issue. Does Apple acknowledge the issue and working on a fix? My battery drains while on the charger. When I got it back, after they said they couldn’t duplicate it, it actually seemed better for a couple of days and now back to draining for no reason.

Same problem here - updated yesterday evening, woke up to an empty watch (never happens). The battery now drops extremely quickly and even whilst charging!

Apple, we need an urgent fix!

exactly the same with my Ultra 2 after the 10.1 update last night

this is stupid

Same issue after 10.1 update. My series 8 won’t charge beyond 15% We need a fix immediately!

I say that after 24+ hours of running the watches full tilt and burning them up internally, they owe replacements

Watch uses a LOT of battery

see all the remedies in here. The vast majority of users find 10.2 has good battery life.
