I have no idea what would cause this, but after updating to Sierra, it now takes about a third more time to charge my Forerunner 235 than it did when I was on El Capitan.
I'm using the current Garmin Express, and it's just painfully slow. Anyone else seen this? I'm talking about going from a 22% charge to 100% charge in nearly 3 hours, and the same charge would have taken 2, tops, in El Capitan.
