Apple Ultra Watch 9.3 update battery drain (bleeding out)

They are asking me to bring the watch to a store for service.

I'm pretty sure it will be useless unless they replace it with a new one running 9.2 or lower.

I'll keep you guys posted about it ... if anyone finds any other way, let us know here.

If it was a software issue from the OS update, it would be effecting EVERYONE. It's not. Do the Forced Restart procedure I outlined above.

I've had my Ultra on my wrist since getting up this morning. It's been on my wrist for about 5 hours. My remaining battery is 93% after 5 hours on my wrist.

I Force Restart after every OS update to iPhone/iPad/Apple Watch and Macbook Pro update and NEVER - EVER have battery drain issues.

Apple doesn't support downgrading OS, so there is no path backwards.

Not necessarily. A new OS can have a very different impact on different devices depending on the settings in each one, the apps installed, and connections enabled, among the parameters that could affect this ...

I have already done what you suggested ... no improvement. I did, recharged back to 100%, and it is draining again. 2 battery charges were gone in 24h ...

Support is now offering express replacement (I have apple care+ for the watch ultra)... let's see what will happen.

I had no idea about this forum but have noticed a lot of negative effects from the 9.3 update. Not only does the battery drain like crazy, but my health info doesn’t sync anymore. So I had been troubleshooting the health thing, I noticed it first. Then I notice I am charging twice a day. Before bedtime “10am” and then again before the work day is even over. I have to throw it on the charger around 4pm. It’s notifying me it’s at 10%. Same usage and I am a person of routine. I don’t get many notifications. This is a real issue.

And what happened after you tried any of the solutions people have posted in this thread, which has worked for them?

Don't just respond to the first post in a thread. Read the thread to see if anyone has any suggestions, which work. Which they did and have worked.

Exactly the same problem here, upgraded to 9.3 and went from 3 days battery life to less than one day. Very frustrating. Now have to charge daily to be able to use sleep tracking. Clearly something is wrong.

Apple Watch Ultra

Tried the hard reset, un-pair, and re-pair. No change.

Just did a 40 minute walk, tracked as a workout, with streaming radio to Powerbeats Pro with line of sight to 4G tower. Dropped about 18 percent. Normally this would knock off only a few percent.

It was fine up until the recent software update (9.3)

Apple.... help!

I have series 7 GPS& cellular/ with out using the cellular- I updated to 9.3.1 and battery dropped from 20hrs of charge to under 4 hrs. I soft reset and even reset the entire watch like it was new - and I am still having quick drain issues. Not sure why some are having issues and others not - but any insight on a work around would be GREATLY Apreciated!

It happens with me too. After the first update of the watch and after the update in iPhone to 16.something the watch that were times in the beginning that it drained in less the 12 yours the 100%. I’ve forced restarted with the iPhone and alone and the maximum was 3 days, now is less the 3 days. But in the beginning when I bought the Apple Watch ultra 3,5/4 days easy. I’m very disappointed with. I’ve bought the ultra only for the upgraded capacity in battery and know I’ve to charge in 2,5 days. More one day that the Apple Watch 8 that I had.

I also believe it is either the software update or something going on with my watch to phone communication. I have tried three different watches and they all drain really fast. This was not the case before the update.

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.

I am recently experiencing that my battery charge used to last 2-3 days. Now I am charging daily in low power mode, low brightness, and low utilization throughout the day. Love my Ultra but it was a quick deterioration on this price tag. Please help

same for me, battery full at 06:22 AM in the morning and at 10% around 06:00 PM so 90% in 12 hours ...

Same here. Averaged around 80 hours before 9.2 on a full charge. After 9.2, went down to 70 hours. After 9.3 went down to around 58 hours.

Unpaired and force restarted. Nothing changed.

Please let us know what the average drain per hour now is.
