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 and switches to a new iPhone, 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:


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


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:


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:


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:

Some of the things listed by Jonathan UK could certainly help. Reply back if you’ve seen improvement after restarting both devices. Strange that it suddenly took a dive.


The times that has happened to me is when: (1) I had a background process like the Activity App running (forgot to stop it); (2) when I thought/assumed the watch was on the charger correctly, but it turns out it wasn’t and really didn’t charge (I just put it on each morning an never really look).


If nothing changes after your reboot or trying some of the suggestions from Jonathan’s post, you can try to unpair and then pair. If that fails, then I think starting fresh and adding back one app at-a-time (each day) might do the trick. Make sure you have a few days of good battery life berfore adding any apps. I had to do that recently with my iPhone and found a unique bug that Apple is currently investing how to fix.


Of course, you can always take it in, but it would be worth having them look after you’ve tried some of these things.

Thanks for your helpful tips. I think it has finally been resolved by upgrading ti IOS 4.1 which was available, but I had not gotten a notification for some reason.
