How can I find out which Apps are using my Apple Watch battery power?

Hi

It is not possible to view battery consumption data on a per app basis for your Apple Watch (iPhone battery usage information is available via Settings > Battery).

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

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

The following steps may help, having previously resolved battery life issues for some users:

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

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

Close all open apps on your iPhone and then restart both your iPhone and your watch:

• On your iPhone: double-click the Home button, then swipe up on each app preview to close it;
• Turn both devices off together, then restart your iPhone first;
  • Restart your iPhone, iPad, or iPod touch - Apple Support
  • Restart your Apple Watch - Apple Support

Unpair and re-pair your watch:

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

Under previous software versions, some users reported experiencing 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.

• 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 watch experiences significantly shorter battery life than Apple's examples suggest that you should expect, I suggest contacting Apple Support, making a Genius Bar reservation or visiting an Apple Authorised Service Provider for assistance, including - if recommended - to have your watch inspected and serviced (whether under warranty or via chargeable service):

• Contact - Official Apple Support
