Apple Ultra Watch 9.3 update battery drain (bleeding out)

Anyone else have an Ultra 9.3 update in the last 36 hours that is bleeding your battery? I was averaging 3-4 days between charges as I do not use GPS much and don’t have cellular activated. But it just died before I made it to 24 HOURS from full charge.

Apple Watch Ultra, watchOS 9

So. Due to a crappy update. Now I am tasked with completely starting over. Spending hours to fix something I didnt cause. And in the end we will still not know what caused this. i did not change anything in my phone or on the watch. This is absolutely caused by an update. either the iPhone or watch or both. @apple. can you fix the issue with your flagship watch and not push the **** on the customer!

You aren't speaking with anyone from Apple here. This is a user to user only forum. You obviously have an issue, but not one which is universal. There is no battery drain on my Apple Watch Ultra. None. It's never fun when you get an issue, but to expect Apple to solve something, which does not effect the majority of users makes it almost impossible to accomplish.


There are a number of Ultra users in my office. All are updated to WatchOS 9.4 and no one is having battery drain issues. So, clearly the update isn't "crappy" as you suggest. But something may have gone wrong in your case, so you'll need to work your way out of this.


While it may not be fun, it would be advisable to wipe your watch to factory settings, then set it up as a new watch, not from backup.

That's fine and you're welcome. I'm not sure what you have to disagree with, however? I don't have any battery drain. No one I know personally, who owns Apple Watch Ultra is having battery drain issues, and I know several who own an Ultra. You have however have battery drain issues. If it was caused by the update, why you and maybe a few others, but not the majority of owners? If it was a majority issue, this thread and forum would be flooded with posts. But when you consider Apple has likely millions of Ultra watches and this is the most visited forum on Apple Watch in the world, one would expect this thread to be overflowing with people complaining. But it's not overflowing. That doesn't make light of your issue. But you're going to have to do something about the issue as waiting for or hoping Apple is going to magically release something which addresses this is not likely going to happen.

I don’t know what the answer is, but I can tell you I have reset my watch to new, no restore from backup. And I have reset my phone. Still having drain issues. Got to figure this out. I turned off all apps on the watch that I could. Still No luck. I even talked to apple support and had diagnostic run on phone and watch. No issues with the watch battery. It’s brand new. I cancelled cellular and disabled raise watch.

Curious to know if you have Optimized Battery Level turned on on your Ultra? Open the settings App on the watch itself. Tap Battery and see if its turned on. Then I'd like to know when you get up in the morning and take your watch off its charger (do you charge your watch at night while you sleep?), what is the battery percentage when you start your day?


Optimized Battery Level would have kicked in after the first 30 days of wearing your watch. And typically, you would start the day around 80% (not 100%). What I'm curious to know is if this is why you think you may be having excessive battery drain?

Thanks for the suggestion but I do not have optimized battery level turned on. I never have. I simply take the watch off the stand in the morning and by the evening it is at aroune 28% battery level. Sometimes a bit higher. My day usually consist of about an hour workout and then usual stuff like, sitting, walking, but nothing else using the watch. every now a then, days apart maybe use maps when driving but not often. discontinued cellular to the watch. All these things are normal to what I was doing before all of a sudden seeing this massive battery drain issue. Again, I have tried 3 different watches, (2 series 4 and 1 Ultra). That is the reason why I upgraded to the the Ultra, because I was seeing excessive battery drain on my Series 4. I thought it was just old. Now I see there is a bigger issue at hand.

In my case. I have optimized battery turned on. I didnt charge the watch every night prior to the update as it easily lasted 3 days for me. However, the last few i have been charging overnight as the level is at or below 25% at the end of one day! The watch is at 100% in the morning and yesterday when I posted to this thread it went down far more than is should. This morning I did the charge. It went to the optimized amount of 80%. I removed it at 730am it is now 945 am it has lost 5%. Ill try the reset today. Im am not interested in wiping my phone.

i know, I hated having to discontinue my cellular option. But it literally did me no good. When I needed to use cellular on the watch, the watch was almost dead. I am pretty certain there is some setting on my phone, or the software update on the phone that is causing it. I remove all non-essential apps from the watch. I even tried disconnecting the watch from the phone. When i disconnected the phone from the watch (by turning the bluetooth off) it was great battery life. i will try that again today to see if it repeats.
