I’m finding the same thing as well.The strange thing that I have noticed coming from a S6 to S7 is that charging with the new fast charger is quick but I want to use one of the old charger cables with S7 but unfortunately it is MUCH slower than that old cable charging the S6. Does not make sense at all…. I would expect at least the same speed I was getting charging the S6
Yes... it does not makes sense at all... When starting to charge from low battery (e.g. 20%), series 6 would charge at more than 1% per minute and series 7 charges at less than 1% per minute....I’m finding the same thing as well.
I also have the old USBC charger and has the same problem of the USBA. Really bad. I do not understand why.It's a great incentive to replace your old USB-A chargers (I have multiple) with the USB-C version, but other than that, I agree, it's baffling.
If I get energetic I'm going to put a power meter on the S6 with its charger, then do the same with the S7 with both the "old" charger and the new fast-charge version and see what they're drawing for volts and amps.Yes... it does not makes sense at all...

I started experimenting with an S6 and S7 and old and new chargers this morning. I think you'd need logging to get a complete picture of how they're charging, starting from the same charge level. The PD charging rules result in changes in the charge rate as the watch charges, so you can't just plug in the meter, drop the watch on the charger and have useful information. I will say that in the limited period of time I was watching, I didn't see the S7 charging more slowly on the old charger than the S6, but both watchers were around 80%, not 20%, and I'm sure that the PD rules provide a different charge rate when the battery is that high. My bottom line, though - I don't have data that shows a reliable result either way.Yes... it does not makes sense at all...

I have done that exercise across multiple days always starting from more or less the same level and my conclusions are pretty clear. Starting around 20-30% all the up to 70-80%, AW6 used to charge at more than 1% per minute and AW7 on the old chargers (USBA or USBC) charges clearly at less than 1% per minute.I started experimenting with an S6 and S7 and old and new chargers this morning.

It would be very interesting to have someone start with two watches with nearly equal health levels and at a low charge level (like your 20%) and log the charge rates for both watches on both the old and new chargers.
