This issue has occured several times over the last year. When I go out for a run that takes more than 45 to 60mins the watch will switch off mid session and won't switch back on.
When I Finish my workout and plug the watch in the charger. It registers typically greater than 60% battery. Is there a way to fix this.
Also when I complete the transfer of data to the watch there is lost info such as heart rate step count, even distance completed than when last checked.
