After being on the factory supplied charger for over 4 hours, my Apple Watch series 7 is still only charged to 80%. This seems like an excessive amount of time. I am using the charger supplied w the series 4. Should this matter?
Apple Watch Series 7, watchOS 8
If you are using the charger from a Series 4 Apple Watch, it will charge your watch slowly. Apple Watch 7 is fast charge capable, but ONLY if you use the charger which came with your watch, plugged into a 20w USB C Charging plug.

It sounds as if you may have Optimized Battery Charging enabled. On the Watch, go to Settings>Battery>Battery Health>Optimized Battery Charging. Is it on? If so, the watch will try to "learn" your usage patterns and only charge your battery to 80% if it thinks you're not going to be taking it off the charger for a while. It will charge it the last 20% so that it will be ready when it believes you will be taking it off charge.
While I find optimized battery charging works very well on my iPhone, I'm less pleased with it on my Watch and have it turned off. I charge my watch for about 90 minutes twice a day and the algorithm just doesn't handle that.
While you're in those settings, take a look at your battery health. If you've had the Watch 4 since it was first released, your battery may be reaching the end of its useful life. It it has dropped below 80% capacity, it's time for a replacement/
Just read your post Briang 30 and am glad seeing that the good old USB A original chargers and leads are working still on the AW7 for some then but not all
The only way we got our older series Watch chargers to work was to get a few USB C female to USB A mail adapters and use the USB C lead that came with the AW7 Watch.
Seems you are using the USB A leads which are not a snug fit like the USB C lead
Not perfectly quick like they worked when we got our watches in early Nov 2021 but working.
Try a force restart and try:
Over 4 hours to charge Apple watch 7?
