I recently had the usual issue of low battery life so I did the battery recalibration thing and that cured it.
But now I have a different issue.
I start a ride with 100% battery ride for a few hours battery drains to say 70%.
When I then come to use it again for another ride on turning it back on the battery level is back up to 100% without it being charged.
I tried doing another battery calibration but it’s still the same.
any thought?
thanks.
