Calories burned dropped from 5k to 3k after 44k step hike

[Shaunybs36]

Hello,

I have used my new phone twice now.

S20 upgraded from s9

Downloaded alltrails and strava to track my hikes.

Yesterday I noticed after an 8 mile run calories burned were less than 3k usually its well over.

Anyway today after a 20 mile hike my calories burned were over 5k and literally in the last hour gone down to 3.2k.

Now as i look at my hourly cals burned chart for all the walk the calories burned are flat....

Like somethings changed those hours out hiking to estimated calories instead of actual.

I looked at yesterdays and its the same only for when im hiking does the calorie graph go flat...

Like it does when you arent wearing the watch.

Very odd

@Shaunybs36 Welcome to the Fitbit Community. Thanks for the detailed information shared. 

I'd like you to double check that there are no manually logged activities in your Fitbit Dashboard, this could be the reason why your calories burned dropped. Take into consideration that all activities recorded with GPS will sync between Fitbit and Strava.

Please let me know if this has happened again and if you experience this only with GPS activities. 

Let me know how it goes.
