I have Fenix 5s Plus which is just over 2 years old. The battery charge life has dropped significantly over the past month and currently will no longer hold a charge. After the leaving the watch plugged in to the charger for an extended period and the watch showing 100% charge as soon as I remove the charge cable the watch turns off completly.
I assume this means I need a new battery. Please confirm and also advise stores where this can be done and cost. Pretty poor battery life for a quite expensive watch...
Thanks for your help... Allan
