Ua band/record question

reineke1992

I just got my UA Band yesterday and did my first gym workout with it. I did weightlifting and 20 minutes cardio. So I turn on the ua band feature that measures your workout and it recorded the workout: 55 minutes and burned ~675 calories. I'm just wondering how accurate the calories burned reading is? I'm a bigger guy weight wise, 5'11" weigh 239 pounds. BF over 30%.

I just don't want to eat back more calories than I should.

TL:DR
Is the calories burned based on your UA Band during a workout accurate?

Thanks in advance
