Samsung must use a stronger battery in the next Galaxy Watch Classic model, for example 620 mAh. Also, like the mobovoi Tic watch, Samsung must use a second display for simple clock which can last for about 45 days.
none of that happens here so far thankfully... second day since I updated it, watch is even better than before, passed like 30 hours since last charging it, and battery is still 55%, and the watch is on my hand 24/7 with some activities in between
