I have Tomtom watch. I am not sure about the model but it has Heart Rate and Music with multiple activities options. Its about 3 years old and on 1.7.64 firmware.
I have two issues.
1) The Battery never shows fully charged despite being on charging over night and
2) With in less than a km of running with music on the battery dies.

I had done factory reset once already.
What options do I have to rectify it?
