I recently "upgraded" my watch 4 classic to the watch 7 44mm and I completely regret selling my old watch. The bigger screen and slightly faster interface are nice but the rest of the experience is the same if not worse in some cases.
As most people already discussed, the battery life is miserable for a current gen device (I get around 48hrs without AOD) despite the new and supposedly more efficient processor. It also charges slower than the old watch despite using a fast charger!
What really made me regret this purchase is that in my old watch -even though it was experimental- gestures worked waaaaay better than this watch 7, universal gestures on the watch 4 worked flawlessly and I used it all the time, while in the watch 7 I had to disable double pinch because it kept answering my incoming calls just by lifting my arm to see who's calling.. This is simply not acceptable.
Lots of reviewers already mentioned the sensor data and tracking are not good but I don't have a better tracker to compare and frankly would have forgiven it if that was the only issue, but as a package it unfortunately fails miserably.
