Is anyone else experiencing the heart rate light coming on whenever the device is in your pocket or pressed against something that is not your finger? Even putting a pillow case against it is enough to make it come on. I've even tried slowly lifting my device up and I can see the red light as I pick it up...Maybe I never noticed before but every time I put in my pocket red light shines through...battery died fairly quick today and I want to say that's the culprit.
