watchOS 7 Battery Drain

I was up at 4am today then went golfing at 8am. My golf app lasted 9 holes until 10 am - 2 hrs into the round.

Battery life has dropped from 18 hrs to 6 since to latest software.

My watch is series 5 with cellular. It is just 12 months old and cost £500. Not really acceptable.

Yesterday I had to charge my S4 watch two times when before the update battery would last about 30 hrs. I had previously reset the watch that did not fix the battery drain, neither did changing the battery optimized setting. Last night at about 10 pm I unpaired the watch from my phone and then pair it again to my phone. I used the latest backup on my phone. I slept with my watch on. This morning at 8 am the battery is at 82%.

So it’s looking like I have fixed the battery drain on my series 4 with the os7 update.

I did try the hand washing thing but that didn’t help. I have still got that switched off though.

I then binned of the Memoji app from the watch as I never use it and that’s new and at the same time I unpaired my watch then restored it from the backup on my phone.

today it’s been off charge since just before 8am, it’s now 14:42 and I tracked a five mile walk with gps and still have 80% left in the tank. I’d say that’s back to normal.

I think it was the unpaid and restore from backup that fixed it but if that doesn’t help then maybe it’s the Memoji app.

oh one other thing. I want back to the Nike analogue face as well. So it could be one of the new faces being active that’s draining it. I’ve still got them set but not in use right now.

Same issue. Series 5 non-cellular updated to latest watchOS the other day, went for a bike ride in the morning with a full battery. 4 hours later and i’ve got 15% left. I did the exact same route 2 weeks ago with a usage of around 30%.

I had the exact same problem. I have an Apple Watch 4 and I was getting less than half a day better life after the WatchOS 7 update. Before that, I was ending each day with somewhere around 55 to 60% of my battery life left after an 18+ hour day.

The Fix that worked for me: Unpair your Apple Watch and then repair it to your iPhone. I did this after making sure my phone was backed up to iCloud, just in case. To do this, open up the watch app on your iPhone. In the top left-hand corner select "All watches", click the "info" button besides your Apple Watch icon and at the bottom you'll see in red lettering "unpair Apple Watch". This will take a while, but once it has successfully unpaired itself, just repair your watch back to your iPhone as if it was a brand new watch, except select restore from backup when you're given the option to make sure you don't lose anything.

I hope this helps as it is the only thing that has worked for me.

My series 4 watch updated over night on the 18th. I have always put my watch on at 6:30am before going walking, and wear it all day putting it back on charge before bed. I usually had 35% left at that time. Yesterday my watch went dead right after I returned from my walk. Approximately at 10am. I charged it back to 100%, and at 3:30pm it was giving me a low battery warning. I recharged it once again to 100%. By the time I went to bed at 11:00pm, it was giving a low battery warning again.

Apple Watch 4 and it’s ridiculous. I use my watch all day every day and I usually end up with about 20-30% battery life left by the time I go to bed. (Varies depending on the length of my workouts for the day). Yesterday I ended up below 10% three times....THREE TIMES IN A SINGLE DAY!! I was hoping it was a fluke but I went ahead and removed more than a dozen apps from my watch yesterday and turned off background app refresh on about a dozen more and then left it to charge all night. Woke up to 100% at 7:45am. Went for my regular morning walk and by 9:15am I’m already down to 79%. I have been an avid Apple Watch support even though they didn’t have sleep tracking and now that they’ve added it, the new watch doesn’t even come with a battery to honestly allow you to use it. But if they don’t fix this, I will get rid of this one and I will be an AVID detractor for the Apple Watch. Make it right Apple.

Well I tell you that unpairing and repairing your Apple Watch doesn’t do any good for the battery drain issue!! Indeed now it seems worse!!! WTF!! My Apple Watch 4 GPS+Cellular is basically unusable with this latest WatchOS7 update. This is ridiculous Apple! Releasing an update that basically disables millions of Apple Watches is unconscionable! I can sit on my couch barely breathing and watch the battery percentage drop more than 15% per hour!! Apple needs to do something to fix this horrendous issue NOW!!!!!!!!!!!

Ok, so I followed the advice I read from some posts yesterday and unpaired my Series 4 Watch and added back as a new watch instead of restoring from backup. This appears to have resolved the battery issue I was having after the update.

Same problem with a series 5. I could go 14-16 hours, sometimes with exercise, and have 30-40% battery at the end of the day.

Since installing watch OS 7, I’ve repeatedly found the charge down to 10% when I’ve put it on a charger.

WatchOS 7 is having a major impact on the battery life of my Series 3. I usually end the day with 45-55% battery using my watch from 6:30 am til 11:30 pm. Yesterday, I charged-mid morning and got a 10% warning at 9 pm. Not even a normal day’s use out of a full charge. Oddly my girlfriend’s series 5 has had a sudden loss of battery life too but she hasn’t upgraded to WatchOS 7 yet. Is it possible there’s a server side issue?

I un-paired my Watch 5 (cellular, running watchOS 7) from my iPhone, and re-paired it (using backup of my watch that was stored in the Watch app), and the battery of my watch is now back to normal. Give it a try.

I just unpaired and repaired. I will report back later if it works for me since it seems to work 50-50 with everyone else doing so and posting here. I tried a hard reset last night which didn’t change anything. I have deleted apps, never had the hand washing sensor on and turned off background app refresh yesterday which also didn’t help. I got Apple Supports attention on twitter and DMed them last night but no one ever responded when I laid out what is going on with my watch and similarly everyone else’s. I’ll report back here if someone responds today also.

I have the exact same issue. I even thought ahead and charged my Series 4 Apple Watch before going to bed (got to about 80%), but woke up with my iPhone’s alarm because my Apple Watch had died! I was so excited for this update for Sleep tracking, but it’s unusable if my watch dies even after charging. Very disappointed.

Re-pair and clean setup helped me too. Initially after upgrade to WatchOS 7 on Watch 4 (WiFi) - it drained from 100% to 10% in 15 hours (normal use for me); after re-sync currenlty much better - 100% to 77% in 11 hours. So there is a hope to have back almost 2 days of use as prior upgrade.
