I have a Banglejs2. I've posted before about my heart rate being measured too low. This seems fixed since a firmware upgrade at some point, I don't remember when.
About a week ago I noticed that the HRM was getting really hot, whenever it measured. Battery life went down drastically.
I've tried older firmware versions, factory resets, data&app deletion but it still gets hot. However, the measured value seems correct. What does that mean?
