Re: Band won't charge beyond 80%
As I understand it's a rapid charge to 80% and then regular (and/or trickle?) for the remaining 20%. If so that would go a long way toward managing battery heat and preserving the life of the battery. BTW I sometimes find I can pull off the charger when it looks stuck at 80% and put it back on, and then suddenly see the rarely-spotted 85% or even 90%. LOL
