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.

The battery issue, pertaining to Apple Watches which have recently updated to OS7, has been escalated to Apple; so they are aware of the many cases of people having issues.


If you were to bug a brand new Watch, series 6 or SE, it would have OS7 pre-installed and been extensively tested.


As previously said, following an OS update, there are many background processes which need to be run, and these may have a temporary adverse reaction on expected battery life.


The actions I have been presented with, so far, are to wait a day or two, and see if it improves.

I saw on another thread from someone who tested the beta and they said turning off the hand washing timer helped. I’m going to give that a try and hope they fix it in an update soon. It’s disappointing that the problem existed with the beta and they didn’t fix it at that time.


Every time I workout I’m at half battery life at the end and I’m having to charge twice a day. I’ll keep singing my **** hand washing song for now. 😂

I’ve done a bit to resolve this to no end. After upgrading to 7 I’ve had huge battery drain on my watch the same as everyone else.


So far turned off all the usual suspects:

  • background updates
  • wash hands app
  • location services for some apps such as weather and clock


What I have noticed is that overnight it barely discharge compared to during the day.


A normal day for me is the following:

  • charge to 100% each night before bed
  • start sleep app when I turn the light out
  • put into airplane mode
  • when I wake up battery is about 85%
  • turn off airplane mode and sleep app
  • lose 7-8% battery per hour. 4 hrs after I woke up this morning and it’s now 54%


It seems the only thing I can do if I want a decent day of life is to put into airplane mode for most of the day and turn it off when I do a workout.

i chatted with someone on the Apple

Support app. He said we need to bombard Apple Support with this issue to get a fix issued immediately. Without this might not get their attention. Here are steps:


1. Download the Apple Support (not Apple

Store) iOS app


2. Select your Apple Watch.


3. Click on Battery


4. Request a chat


5. iMessage window opens immediately with Apple support. In the chat explain precisely what happened and demand a fix.

I'm having this issue as well; having to charge 2x per day at minimum. One thing that I've noted is that the location services indicator is on virtually all the time (swipe up on Watch. solid purple arrow is present upper right above WiFi button) I'm not working out or even moving much and something is constantly hitting loc services. i can ;literally watch the power %age drop.


Series 4 Nike. no [power drain issues noted prior to update to OS7. Battery health is rated at 100% by the Watch app. Not sure how long that'll hold up with this constant charging requirement.

Thanks Dgraugh. This was first posted here by Gerard Leeb. I also reposted it as it worked for me but I also had to toggle Bluetooth off and on. Then it just stopped working after awhile. I may go through the steps again or just wait for Apple since the critical part was getting the battery performance back to normal which it has been since September 20th with the Unpair/Pair procedure from a Backup.

I was having issues with my randomly shutting down when it though it was out of battery when I was using it for running and using the Strava app on the watch. I bought a Garmin Forerunner 935 and gave up on the Apple watch for running. There is one park I run in that is the death zone for the Apple watch with Strava. It dies before even 3 miles. So this week I went to this park for a run and my Garmin watch died (my fault for not charging it). I tried using the Activity/running app on the Apple watch and no problems. So maybe my problem all along was a bug in the Strava app. I am going to keep using the Activity app and see if it is reliable.
