Apple Watch Battery Drain and WatchOS 7.5

I have this issue too, 6 hours battery time. I sent in my watch and the returned after spending less than an hour trying to reproduce the problem. I then spent 15 hours troubleshooting with Apple support.. running diagnostics, collecting logs etc. The logs confirmed that the battery health was good but that the battery was drained abnormallu fast. So after having the issue confirmed and jumping through hoops for 15 hours or more I was informed that it probably would be a paid repair... despite Apple not being able to tell me what the problem is. Thank you Apple indeed. I will be upgrading to another brand of paper weight.

Ive had the same issue, with the battery draining fast on my series 6 watch (with virtual SIM) .... especially overnight 80% loss!

The only way I found to resolve this issue was to keep my iPhone within bluetooth distance of my watch and switched on (even overnight) now only 15/20% loss.

Doing this resolved the battery problem, Im guessing if the Watch is not near the iPhone it has to use more power communicating via 3G/4G itself with whatever its doing?

I also just updated my watch recently and experienced rapid battery loss, I saw some other post about unpairing and repairing to solve the issue but now I cannot pair my watch w my phone. I’ve tried to my knowledge every trouble shooting in the book…any suggestions?

Watch w pair then go to a screen that says “Connecting with IPhone this may take a few moments” and then it will automatically unpair

Watch OS8.1 is not helping battery life either... Series 4 stainless, have the 44mm and my fiancé has the 40mm.. We both are having major battery issues at the same time... so this cannot be hardware related..

Yep, no fix with WatchOS 8.1, hard reset and unpairing are fruitless fixes. Had ZERO issues with my series 5 40mm until wOS8, battery would last all day and when I would go to bed at 10:00 pm it would be at 30% and that was with ALWAYS ON enabled. Now with everything set to practically no background refresh and no always on, I'm at 30% battery by 1:00 pm!! And then it goes into low power mode an hour later. This is unbelievable that this update hasn't addressed this KNOWN issue!! New features are useless if the update affects battery life of hardware.

I've had my Apple Watch series 4 drain ten times when just minutes before it was charged. After the first couple of times, I sent it to Apple, but Apple returned it to me. I have unpaired it and paired it, but the problem persists.

I have not. Nothing but crickets from Apple. Pretty sorry charging this much for a product and then not supporting an issue that is not a user problem. I used to be a huge Apple fan but the customer service taking care of issues has gone downhill. No longer an Apple fan.

Mine is doing the exact same thing. I also tried re-pairing the watch to no avail. So frustrating. Apple should have to fix this for us.

Agree. But what made it fix itself for a few days for me. After I reset and set it up as a new watch, the battery life was reasonable for several days. And then last night something happened.

It has happened before with software updates and normally they have fixed it. Hopefully they are aware of the issue.

Ditto on a series 3 w/ cellular. Doesn't even last the day. Always used to. Definitely a 7.5 issue. Tried the unpair/reset, didn't improve it at all.

My watch (80%) sat on my dresser all night and thru 6 hours. When I finally picked it up it was down to 10%. This is also after the update and resets.

Apple Watch battery is not listing even a full day!!

Update virtually killed my S3. 2 hours use on full charge. I wiped and repaired 5 times with no improvement.

As last chance I erased and resynched with an old OS copy (4.2) and it’s working again…
