I have been having weird issues with my edge 520. Every now and then after an indoor training session I'd turn it off with about 60-70% of battery left.. go ride outside the next day and boom - battery drained after 5-10 mins of riding. Had the original replaced and still seeing the same issue with the replacement unit. Anyone else having the same problem? The latest firmware, GLONASS turned off (I am in North America)....
