The charge times (from a 0% battery charge to 100%) both times were 2h 53m 2s and 2h 58m 17s respectively (timed using stopwatch on paired iPhone and battery monitored using the battery widget).
I understand that the battery is marginally bigger than the Apple Watch S6, but that charged from 0% > 100% in circa 1h 30m so doubling the charge time is not representative of the increase in battery capacity.
Is this is software issue? It means using an old charger is no longer feasible to the point where my existing cables are now pretty much redundant (although my other half will now have a number of spares). Does anyone else still experience the same issue or has anyone else seen better charge times?
Fwiw - the fast charger works exactly as it should - I guess it's Apple's way of making me buy more new stuff!
