Gaps in Activity data after iOS14 update

After updating to iOS14, my activity data is not fully syncing with Health. Calorie, exercise, stand and step *counts* look perfect on the watch and iPhone Fitness app, but there are gaps in the phone’s Fitness app *graphs* (e.g., Fitness app reports 77 mins of exercise, but only graphs 16 mins; reports 13 stand hours, but only graphs 4). This wouldn’t be a big deal, but the activity data that is then pulled into the Health app (and then shared with other fitness apps) seems to only reflect the smaller of these numbers (16 mins exercise, 4 stand hours in this example). These numbers all matched perfectly before upgrading. Tried prioritizing the watch as a data source, unpairing and even factory resetting watch, but this did not resolve.

I finally got it to work with the help of Apple support. Everything now works as it should, but I’m still disappointed this happened in the first place, and tHat it took almost hAlf a day to get everything set up back the way I like it.


here were the steps that worked for me:


  1. unpair apple watch
  2. make an iCloud backup of the phone
  3. go to the health app, click on your profile (top right) and look at the bottom when the data was last backed up - it should be the same time as thE Back up above.
  4. erase all Contents and settings of your iPhone.
  5. set up your iPhone by restoring it from your last backup
  6. finally pair your watch again.


then wait until everything is restored, it will take a while until all apps are downloaded again, also until all health data is fully restored. I thought for a while that I lost most of my data, but it might take 24 hours until all data is back.

it will not correct any missing map data from past runs. But today’s run shows the course I took.


last gripe: I was on a steak of 811 days of making my move target. But because the prior days calorie data was the last to be restored, it appeared like I didn’t make my target yesterday, and the streak ended. Although by now all the data is back, it looks like the count is starting over.

Same here, and not all activities are syncing to my phone. 2 HIIT Trainings done with the watch, but not on the phone. But some activities do transfer, e.g. outdoor walks. But these are buggy (no heart beat, and the map only shows the starting point, but not the course). Synchronisation between Watch OS7 and iOS 14 is definitely buggy.

Got my series 6 watch yesterday, and sad to report that it didn’t improve.


the bars in the iPhone don’t match the bars on the watch, and the map from my outdoor walk doesn’t synchronize (only shows the starting point).

the activity app shows the right number, but wrong bars, but worse, the health app only. Ousts the lower number, or responding to the bars. Something is seriously off!

Got my own answer. No.


health app not synchronized with the activity app. Activity app’s numbers are synchronized with the Apple Watch, but not the graphs. Outdoor walk recorded, nut no map data available other than the starting point. Since first reporting this problem, I did the following:

upgraded my watch from series 4 to series 6.

unpaired/re-paired the series 6

force restarted iPhone (11pro max)

force restarted Apple Watch.

reset sync data via watch app (is that even supposed to do anything? It seems like it’s not doing anything)


i have the watch because it was a great fitness tool. Right now, it just tells time, like any old watch.
