Was working with oder Version!!
I purchased an Edge 1030 this spring, and I think it came with firmware 7.50. The battery percentage worked fine until I upgraded to 8.00, then it got stuck at 100%. I'm not sure if it started working correctly (i.e. decreasing from 100% without a full power cycle) after it all of a sudden powered off during a ride. After upgrading to 9.00 it was stuck back at 100% until I power cycled it tonight. My point is the battery percentage did work for me after firmware 3.90 but before 8.00. Is the solution that one must fully power cycle between rides or just after a firmware update?
