Battery drain on watch series 7

This may be a shot in the dark, but worth trying since you're stuck.. I saw you did say your iPhone is on 15.4, so that is a must.

First, try updating via the Watch instead of the Watch app on the iPhone. On your watch, go to the Settings app in the honeycomb layout and try General > Software Update from there.

If that is unsuccessful, try the steps below:

Unpair the watch and wait until you see the "setup" screen on the watch, so you know it's not linked to you.

On your phone, go to Settings > General > iPhone Storage > Scroll down until you see the Watch app.

Remove all of your backups for the watch.

Delete the watch app.

Reboot your iPhone and Apple Watch.

Reinstall the Watch app.

Pair Watch again and check to see what software it's on after complete.

If it's not on 8.5, try updating again from the Watch App.

I replaced my series 3 for a series 7, and was also shocked at the lackluster battery life. However, I fixed it by removing several fitness apps as I suspected they were doing too much in the background. I kept all of my health apps, and from a fitness perspective, retained cyclemeter, keelo, and alltrails. I removed myfitnesspal, freeletics, and strong so one of those 3 was the culprit. Today I have 64% battery life remaining after 15+ hours.

Apple needs a battery app for the watch so that you can see who the offenders are. That helped me years back when I was having iPhone battery challenges. It's not the watch, it's the apps (and we need better diagnostic capabilities).

I went to the genius Bar and the option was- they send it back for repair and you leave empty handed or you call the 1800 number and get a credit hold for a replacement Watch while it’s repaired. I decided to do this option and found out I needed to buy apple care plus. So I did and now I have a replacement. The battery seems a little better and no wonky behavior so far.

You mean the Steve Jobs who told the entire world they were holding their phones wrong? Please don't elevate him to sainthood. A brilliant man he was, for sure. But he had loads of problems with products and had a storied history of NEVER publicly admitting anything.

I have two Apple Watch Series 7. Neither have any battery drain issues. None. My watch went on my wrist at 7:30 this morning. I didn't do anything over battery intensive during the day. Took an ECG. Read my oxygen. Took a phone call or two. Read a few text messages. And when I got home tonight at 6:00 PM, the battery remaining on my watch was 74%. Some days its higher. Some days its lower, but every day, it never runs out of juice. Same with the other Series 7 we own.

It's simply virtually impossible you've been so unlucky to have so many watches ALL with the same issue. Clearly something is running your battery down. I would unpair it from your phone and NOT set it up from a backup at all. Introduce apps and features individually and see if something drains the battery. Turn off Background App refresh (it's just not necessary anyway). Use notifications for only those things you actually need to be notified about.

I am thrilled to report that watchOS 8.5 FIXED mine and my fiancé's S7 battery issues! It's been a week straight now, new record.. I leave ALL features on and get over 20 hours of battery now.. Incredible.. My 4 month troubleshooting nightmare is over... I reeeeeeeeeeally hope the next update doesn't break it.

I am not sure if you have a solution yet, but the below should help.

Apple Watch Series 7 has the feature ' Always on' display . Turn off the feature if you have not already. Open the Settings app on your Apple Watch. To do this, press the Digital Crown to see the Home screen, then tap the Settings button . Tap Display & Brightness. Scroll down, then tap Always On and turn it off. This will drastically improve your battery life.

Cheers!!

Me too, but a relatively easy fix:

Power down Watch completely.

Completely delete watch app from phone (unpair).

Power down phone, then power up.

Pair watch again but as though it were a NEW watch.

You’ll have to reset everything.

My battery was finally good after 8.5, then started draining quickly again after 8.5.1. This was resolved by rebooting every time I would notice it starting to drain quickly. I only had to do the reboot for a few days in the mornings, now I don't have to. I can usually tell if I'm going to have a good battery day if I stay at 100% for the first hour and a half in the morning. Then by the end of the day, I normally wind up with around 3% per hour battery loss, which is awesome. So, I would recommend rebooting if you notice battery loss after 8.5.1 and put back on the charger till 100.

Try turning off always on display feature

Upgrade your iPhone to 16, then your watch to 9. The problem goes away! Why??? Buggy software....

If you can, than try this (not main):

Based on some comments from that thread I had found, what I did once I had worked with Apple to be able to log out of my Apple ID

Reproduced comments

1. Shut down ALL iOS devices

2. On Macs, I ran (first one deletes a database about trusted devices for the AppleId):

> rm -f ~/Library/Keychains/*/com.apple.security.keychain-defaultContext.TrustedPeersHelper.{db,db-shm,db-wal}

Followed by (which resets "CuttleFish" - can't find any documentation on this but I believe to be an iCloud service for syncing this database):

> tpctl reset

I then shut them down.

3. With all devices shut down, I booted a single Mac, and went to preferences and re-signed in as prompted (reseting the cuttlefish service seems to lose all the device trusts I guess - but doesn't actually sign you out of iCloud).

4. Once signed in, I reviewed the list of devices associated to the AppleId, and cleaned them out.

5. I rebooted the Mac and left it for 10 minutes to re-build the local database deleted earlier.

6. Booted another Mac and signed in and waited for its keychain to rebuild and rebooted it.

7. One by one, I restarted iOS devices, signed them back in from settings as prompted.

immediately my iOS devices are drawing a normal amount and TrustedPeersHelper on the Macs are using pretty much no CPU time.

I didn't try exactly all these steps yet, but it gave me an idea.. I opened Apple Music on my Mac to get to Account Settings where I can manage the devices associated with my Apple ID.

I removed all the excess devices I no longer have.

Shut down my phone and watch

Put my watch on the charger to reboot and charge back to 100%.

Turned my phone on as well.

Took the watch off the charger when it got to 100%

Unlock to sync with the phone, wear it...

SO FAR, I have only lost 10% battery over the last 5 hours, which is incredible... but I've also learned not to get my hopes up about this thing. I had a stretch of 4 days back in January where my watch was fine, so I'm not going to say all is well quite yet.

Will report back if I can make it a solid week with no issues.

I just got the apple watch series 7 a couple of weeks ago and have been experiencing short battery life. Even with most functions/ background app refresh etc turned off, the watch can only last 10 hours after a full charge. It can barely get through a work day. Battery % drops close to 10% per hour.

Have tried resetting, unpairing etc, hasn't worked to resolve this issue.

This happened on watchOS 8.1.1 and 8.3.

Does any one else have this problem?

Have you updated to watchOS 9? I get about 24 hours on days I don't do a workout.

If you read Apples reply to the original post they say it will only hold a charge “up to” 18 hours. That’s BEST CASE scenario. Return it!
