Hello!
I noticed a new issue when calculating intensity minutes in my Garmin Vivoactive 6.
Until December 3, 2025 intensity minutes data calculated over the week was correctly reflecting activities logged and everyday life. However, in the date mentioned I noticed a spike in "intensity minutes" that is inconsistent with the activities of the day.
Below you can find a snapshot of the daily timeline for yesterday (December 8, 2025)
From the image above you can see:
- Activity Minutes is correctly recorded after activity is completed, which moved the graph line to ~100 intensity minutes for the day
- Then, around 11:30 PM (bed time) there is another "jump" of ~100 minutes, almost doubling the minutes recorded for the day
- It seems to me that the intensity minutes for the activity are logged once again before bed time
The same pattern has been happening since December 3, where intensity minutes spike happens in the end of the day right before my bed time.
The issue started on Dec 3, 2025 and it still present to the day of this posting.
Can someone from Garmin please take a look and fix this issue when possible?
NOTE: I use HRM-Pro Plus HR band when exercising, and have been using it for over 2 months and the data was correct - until December 3 when this issue started.
