Heart rate higher during walk than during aerobic workout

[Jadeymas]

Hi, 

I have a charge 3 synced to an iPhone 6. 

I am consistently getting higher heart rate recordings for non-strenuous walking than during aerobic workouts like HIIT. 

For example, today’s exercise:

43 minute walk - average 117 bpm, 276 calories

30 minute aerobic workout - average 97 bpm, 113 calories

This cannot be right, and it surely means that the calorie tracking isnt reliable. Does anyone else have such a problem?
