Apple Watch update 10.4 stuck at Preparing

Same issue. Stuck in Preparing and then loses charge.

I am unable to delete when its stuck in preparing. How do I delete the software update?

Can you guide me on how to delete this terrible update?

Thank you so much! Nothing had worked for me until I did your exact sequence. Now it's installed, and I can stop worrying about it!

I have same problem. Apple quality control is suffering !

So,i have a problem i have an apple watch 6 and it was on os9.6 so when i got an update of os10.4 it started to get stuck on preparing and after 2-3 minutes it started to say update failed so i unpaired the watch and reset it and now i cant even open it because first it says i have to update it

I've got the same problem and tried all the same things too. Had the same issue with the last update but it seemed to resolve itself with the reboot. Not this time though.

Have the same issue. Apple Watch 9 stuck on Preparing when trying to update to 10.4

I was finally able to update my watch to 10.4 after 3 attempts and deletes as listed below. It finally updated on the 4th try. I did have the same problem before the update, losing battery power in a few scant hours! I’m ok now. I think.

I’ll add to the pile… done the whole deleting thing, restart phone, restart watch… same result multiple times.

This is just as bad as Windows’ update last year that required manual partition expansion! Don’t be like Microsoft and wait months to address it or leave users to figure it out first! (lol… as if Apple reads this stuff)

I deleted the download, stopped all applications on the phone, stopped all applications on the watch, restarted both the phone and the watch and I will ignore the application until it auto-updates overnight. I am giving up on trying to initiate the watchos update.

Same issue with mine. Series 9 Apple Watch, tried all the steps multiple times and it’s still stuck on preparing update. I need the update because the battery just runs out within a few hours. Nearly missed my alarm because of it.

Have given up to update to 10.4 Tried six times and paired watch again an set automatic update to no.

Battery empty overnight after charging in the evening before.

Wait for another update and even then wait a while.

according to Apple, I have 46gb left on my iCloud storage family plan and yet I still can’t get my watch or my husbands watch to update. They are stuck on preparing and draining the battery. Any other suggestions?

I'll add to this dumpster pile! My watch died during the night while wearing it even though it was at 100% when I went to bed. It has always been between 78-85% each morning but was dead. Recharged to 100%, worked out and an hour later battery was down to 10%. Tried to update to 10.4 and it stuck at "preparing". I deleted the download file, unpaired the phone, repaired and tried to download update again to no avail. I'm assuming Apple knows about this issue so hopefully they will get an update out soon that actually works! My watch doesn't last 2 hours anymore without dying.
