Apple Watch Battery drains after Pairing with iPhone X

Hi

Battery life varies depending on use and other factors. Examples are detailed here:

Apple Watch - Battery - Apple

Apple's tips for maximising battery life on Apple Watch are detailed here:

Batteries - Maximizing Performance - Apple

If your Apple Watch is experiencing significantly shorter battery life than Apple's examples suggest that you should expect, then it may help to follow these steps, which have previously resolved battery life issues for other users, including after software updates when usage has not otherwise changed (check after each):

If you have not yet done so, update your iPhone and Apple Watch to the latest compatible software versions, starting with your iPhone:

• Update the iOS on your iPhone, iPad, or iPod touch - Apple Support
• Update your Apple Watch - Apple Support

Restart both your iPhone and your Apple Watch, turning both off together and then restarting your iPhone first:

• Restart your iPhone, iPad, or iPod touch - Apple Support
• Restart your Apple Watch - Apple Support
• If the issue persists, next close open apps on your iPhone and then restart both devices again.

If you have ever (not necessarily recently) previously used the Workout app and/or any third-party fitness or sleep tracking apps to record workouts on your watch, check on your Apple Watch to see whether there is a paused activity within any of them. If there is, end that activity from within the app on your watch (not your iPhone).

• If in doubt, remove any such third-party apps from your Apple Watch.

Unpair and re-pair your Apple Watch:

• The Watch app on your iPhone takes a backup of your watch automatically when unpairing via the app.
  • When setting it up again, initially choose to Restore from Backup. Most data and settings will be restored, with some exceptions (eg Apple Pay cards, passcode).
  • If the issue persists, consider instead unpairing and setting it up as a new watch.
• Unpair your Apple Watch and iPhone - Apple Support
• Set up your Apple Watch - Apple Support

Some users have previously experienced battery life issues in connection with using corporate profiles and/or Exchange Calendars. If you are using an Exchange Calendar, one or more of these steps may help:

• Archive your Exchange Calendar for all items before today.
• Remove / delete all old inbox messages relating to calendar invites (accept and decline notifications).
• Create a rule in your Outlook Mail account that moves all future accept and decline replies, immediately upon receipt, into a separate mail folder that does not sync with your iPhone and Apple Watch.
• Check your Exchange Calendar for errors.

Finally, it may help to:

• Remove third-party apps from the Dock and/or from your watch and then monitor battery performance after adding them back, one at a time:
  • Open apps
• Remove watch face complications and monitor battery performance as you add them back:
  • Change the watch face on your Apple Watch - Apple Support

Having tried the previous steps, if your remain concerned that battery life is shorter than it should be, then I suggest contacting Apple Support (remote diagnostics and/or mail-in service may be available, if required), making a Genius Bar reservation or visiting an Apple Authorised Service Provider for assistance:

• Elsewhere: Select your country for Apple Watch service and repair information

As I explained in my previous reply:

I am experiencing the same issue. I switched from iPhone 6 plus to iPhone X and the battery of my Series 3 Apple Watch drains faster than before. The numbers are similar to the thread starter's. Hope we can find the issue there.

Then follow the same steps in my previous reply.

I had the same problem. I purchased and installed an Apple Watch 3 and three weeks later installed my iPhone X. My watch had been working perfectly, and then all of a sudden the battery started to drain very quickly. I followed the instructions below, rebooting my phone and my watch. That did not work. I then unpaired it, paired it again and it seems to be working just fine. I am not a techie, by a long shot, but I think the problem was related to how I installed my iPhone X, without properly unpairing my watch from my prior iPhone. It seemed like it was continually seeking the old phone. FWIW.

Hi

I have the exact same issue. I own a Series 2. The autonomy was about 48hrs with my iphone 6 with ios 11 and after pairing it with my new iphone X. It has dropped to 15 hrs. (Watch dies before I even get home) Is there a way to check what app may drain the battery? I haven't install any new app, only have activated Apple Pay. Could that be the reason?

I hope Apple can look into this issue. It's just a huge drop in battery life.

I am having this same issue. Series 2 latest OS, Iphone X 1.1.2. I have hard reset both, re-paired and wipped watch to no avail.

Took watch off charger at 6:45 AM EST it is not 12:36 PM EST and I am at 10%.

Something is going to have to give and give real quick.

Hi,

I encountered this problem too. Apple support did not gave me any solution.

I finally reset my watch, WITHOUT restoring any backup. And now I've a nearly two days of battery again !

A good solution for me, as I've nearly no third party app on my watch.

Benoît.

On it. It's just a longer process and sounds a bit "generic". But I hope it helps. :-) Thank you for your input!

To confirm your suggestions, Jonathan UK: Turning both devices off and turning the iPhone X on first seems to have solved the problem. Thanks again.

You're most welcome! 🙂

i did the same but my apple watch still draining battery so faster... i don't know anything else to do....

I have all three versions of Apple Watch. All were reset and re-synced to iPhone X. None of them will hold a charge for more than a single business day. That is completely unacceptable.
