Hey so I hav been notching my heart rate goes up to 159 to 170 while sleeping. I have no symptoms neither do I wake up in the middle and feel this but can this be a glitch. I havea charge 3

I have a glitch on my Charge 2 where it sometimes randomly goes up that high or a little higher (180s). It's a fault.

I have had a high heart rate after carrying a heavy object up a steep hill it was 182.

I would check it when  not a sleep.. Try it with the non sensitive setting.
