Last night I noticed that my Fenix 5x was dead, which was kinda a shock to me because I charged it not long ago. Assuming I just used the GPS mode a lot over the weekend, I put it on the charger over the night. Woke up to find that my Fenix 5x doesn't hold a charge. The watch says it's at 83% but when I disconnect it from the charger, it immediately dies. Then when I turn it back at 83%. Has anyone had this problem where is doesn't hold a charge? I don't remember doing anything aggressive that could have caused this.
