Active calories too low with Fenix 7s pro

Hello, with my new Fenix 7s pro I noticed a fault in calories calculation. If I compare to the old Fenix5s the active calories for same activity are150% less. As an example, today 12 km hike tour showed only 200 kcal which is not possible. Is there a calibration or any way to correct it? Thanks

Active Calories are based principally on the heart rate during the activity, on the 7days avg. Resting HR, on the Max HR, on the body parameters, and your training & fitness history (i.e. EPOC, VO₂max, LTHR,...). If you get considerably lower values, you may want to compare the activities from both devices, as well as the fitness data from the concerned day, analyzing which of the data causes the difference. Often the Resting HR and the Max HR values may cause a significant difference, but all the other mentioned metrics may play a role in it too.
