Watch OS 3 Draining Battery Very Quickly

Since updating to Watch OS 3 last night, my Watch's battery life depletes ridiculously fast. Every 20 mins, I witness a battery drain of at least 4-5% without usage. It is even worse when I am using the workout app. I have turned off background app refresh and the problem still stays. I've also tried rebooting the phone & watch as well as unpaired and restored from backup. Still nothing.

Hi


Battery life varies depending on use and other factors.


In tests, for example, Apple achieved 18 hours of battery life with the following usage: 90 time checks, 90 notifications, 45 minutes of app use and a 30-minute workout with music playback from Apple Watch via Bluetooth.


As you have already tried unpairing and re-pairing your watch, the following further steps may help:


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


Check for and install any available updates for third-party apps on your iPhone and watch.


Check that you do not have a workout running or paused in the built-in Workout app.


If you have ever(not necessarily only recently) previously used 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).

  • If in doubt, it may help to remove any such third-party fitness app from your watch.


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 Apple's examples suggest you should expect, contact Apple Support (mail-in service may be available) or make a Genius Bar reservation with a view to having your watch checked, if recommended by Apple (under warranty, if eligible):

Hi Jonathan, thank you for your reply.


I undestand that apple provides general information about the battery duration while performing some usual tasks; what I would like is to have information from someone that already used the watch on previous version of WatchOS and now have upgraded and continue using the same applications in the new OS.

Yesterday I made the same bad experience. After installing watch OS 3 I created a new face based at the "Simple" theme using the complications: messages, calendar, heart rate and weather (temperature).

After 12 hours of normal use (no hard working or moving or so...) the batterie runs out of energy. After reloading the watch and switching back to my former favorite theme "Chronograph" the watch looses 8 percent of batteriy life during 6 hours... The configured complications are moonphase, activity, temperature and the horrible always automatic on-switching timer.

By the way: is it possible to use the Chronograph-theme without the app in the upper right corner?

YYesterday was my first day out with watch os 3. Normally I had 30 percent battery at the end of the day. Yesterday it was 10%!


even allowing for more use because it was a new os, this is a big shift. It has also seen my iPhone 6 battery die very quickly.


digging around, I see Apple have now allowed apps to background refresh. Maybe this is using the extra battery.


every app by default seems to background refresh. I have disabled this for most apps, except the ones I use regularly. I will see what difference that makes.
