watchOS 7 Battery Drain

I updated my series 4 Apple Watch to WatchOS 7 today. I use my watch all day and usually have about 30% battery left when I go to bed and start changing. Today my phone got to 10% by 2:30 pm! Why is this drawing so quickly?

I had the same issue on my Apple Watch Series 4 after updating to iOS7. I tried shutting down background app refresh, and ensured sleep app and hand washing apps were off.


This didn't fix issue so I read on some other forums about repairing to your iPhone. So I did a reset on my watch. I restored using the same backup I just reset and today the problem seems to be gone. After a 2hour walk I have only went down 13% which is normal level. When I was running out of battery my watch was showing a 35% drop after my walk.


if restoring from the backup didn't work I was going to try setting up as new watch but obviously I didn't have to go that far.

Need help! I unpaired my watch while keeping it on my wrist and then repaired my watch from my backup. I did all the unpairing and repairing from my iPhone 11. Everything worked except my battery is dropping even faster. I turned on the activity workout and I am losing a percent a minute with the activity going. My watch is a Series 4. I even turned off the phone and the watch and restarted them. What did I do wrong?

I believe the issue is related to some form of processing staying on even after a workout is ended. I noticed that after a work out if I turn off my watch and turn it back on I do not have the battery drain issue. If I do a work out and end the work out and leave my watch on it drains my battery a ton. My thought is there some kind of process running in the background associate with a work out that is not turning off when I work out has ended. Although doing a restore would be a forever solution I’ll just deal with the hassle of turning my watch on and off

I just got off a chat with Apple Support. They had me send them a diagnostic and because I had just done an unpair and repair there was not enough information on the diagnostic report. I have to keep the watch going for at least 6 hours and then contact them again. They did say the Hardware was ok. They would not comment if they were having any issues with the SW update. 🤬

The issue persists. Series 5 LTE. I used to be able to make it longer than 24 hours with about 20 percent or so to spare. Update didn’t work. Repairing from a backup didn’t work. Repairing as a new watch didn’t work. 13 hours and I’m at 18 percent battery left. This isn’t usable. I have even turned off stuff that I had enabled in OS 6.

FWIW - I've tried unpairing/pairing from both backup and as new (Series 5 watch). Neither worked. Hand washing is off. Problem seems much worse when on LTE - watch loses 30% in less than half hour. Prior to upgrade battery loss was negligible over same period when using workout app and listening to music downloaded to watch. Two chats with support. First suggested unfair/pair as new. Second gave me a link to maximizing battery life (worthless the watch isn't even a year old) and then made me an appointment at local store. Very frustrating that there seems to be no acknowledgement that there might be an issue with Watch OS7
