Why is my Apple Watch battery dying so fast?

Hi

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, including after software updates when usage has not otherwise changed:

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

• Restart your iPhone, iPad, or iPod touch - Apple Support
• Restart your Apple Watch - Apple Support

If you have ever (not necessarily recently) previously used the Workout app and/or any third-party fitness tracking apps to record workouts on your watch, check on your 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 third-party fitness app from your watch.

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, 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.

• 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:
