Q: Apple watch battery

Hi

The following steps may help:

• If you have not yet done so, update your iPhone and Apple Watch to the latest software:
  • 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 devices:
  • On your iPhone: double-press the Home button, then swipe up on each of the app previews to close them.
  • Turn both devices off together, then restart your iPhone first.
  • Restart your Apple Watch - Apple Support

• Unpair and re-pair your watch again:
  • 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

• If you have ever previously used the Workout app and/or any third-party fitness tracking apps (such as Strava) to record workouts on your watch, check on your watch to see whether there is presently a paused activity within any of those apps. If there is, end that activity from within that app on your watch (not on your iPhone).

• Under earlier 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 all third-party apps from your watch and then monitor battery performance after adding them back, one at a time. The same applies in respect of watch face complications.

Having tried the previous steps, if your watch continues to experience significantly shorter battery life than usual, contact Apple Support (mail-in service may be available) or make a Genius Bar reservation with a view to having your watch checked (under warranty, if eligible):

• Contact - Official Apple Support

For future reference, there is a difference between your devices being "unpaired" vs them becoming temporarily "disconnected".

If your watch becomes temporarily disconnected from your iPhone via Bluetooth and cannot connect to a known Wi-Fi network at the time, it will show the Disconnected icon on the watch face:

Such disconnections can be normal, occurring whenever the paired iPhone is unavailable (such as during iOS updates or when your iPhone is out of range).

It is not normally necessary to unpair and re-pair your devices after this happens. They should instead reconnect automatically a short while after being brought close together again. If they do not, keep your iPhone and Apple Watch close by each other and follow these steps until they do:

• Check that both Bluetooth and Wi-Fi are enabled on your iPhone:
  • It may help to toggle Bluetooth off and on again on your iPhone (Settings > Bluetooth).
• Check that Airplane Mode is not enabled on your watch:
  • When viewing the time on your watch, swipe up on the watch face > swipe left / right to the Settings Glance.
    • If the Settings Glance states Connected and the symbol at the upper-right corner is a green phone symbol, then your watch is connected to your iPhone via Bluetooth.
  • If your watch is not connected and Airplane Mode is turned on, tap the button to turn it off.
  • It may otherwise help to toggle Airplane Mode on and off again.
• Restart both devices, turning both off together, then restarting your iPhone first.
  • Restart your Apple Watch - Apple Support

For the best performance from your watch, keep both Bluetooth and Wi-Fi permanently enabled on your iPhone.

If they still do not reconnect, only then should you unpair and re-pair your watch:

• Unpair your Apple Watch and iPhone - Apple Support
• Set up your Apple Watch - Apple Support
