I had the same thought as this resolved some battery calibration issues on my iPhone some time ago. More details at https://www.macrumors.com/how-to/force-restart-your-apple-watch/ or https://support.apple.com/en-us/HT204510. Apple appears to describe it as a "force restart." I suspect a full erase, re-pair to iPhone, and restore might do the same, but it could still be that some settings are carried over from the backup that shouldn't.
Thrilled to know I'm not alone here though I've never been more pissed off with an Apple product.
Nope, definitely not alone. My wife had the issue with two different Apple Watch 5s, I had it with one, and she's been hellbent on not buying anything Apple after the bull***t way they handled it:
A replacement is better than those claiming hard resets.
Did you and your wife finally get your hands on properly working replacements or were they all still junk?
And that gift situation - yikes!
Not even sure if it's worth pursuing at this point...
Maybe I should've added that hard resets were also a problem, though candidly the worst issue to us was still having the watch die while indicating 60% plus battery life while out and about with no other device except for that LTE Apple Watch.
100% at 6am today. Dead by 2pm. And that’s a replacement.
Yep, that's pretty much it right there in a nutshell. Every bit as bad as the keyboard issues. Sorta pathetic.
Temporary fix is to charge to 100% and the and then turn the watch off for at least 30 minutes off the charger. This somehow recalibrates the battery. It definitely isn’t a permanent fix because I’ve had to do it about every 3 weeks, just did it yesterday.
I was given the same BS runaround by Apple that it’s fine and I even had it sent in for testing, was told it’s 100% fine even though it also somehow came back with a software update rolled back. This is definitely not the same Apple that cared about helping customers have positive experiences with their products.
Are you sure it was the same watch, i don’t believe even they can roll back firmware upgrades on watches.
Unless they are reassigning the serial numbers to the replacements now. I literally got the email it was received by the service center and an email that it was back in the mail to me within 15 minutes of each other. Came back with the exact same battery issue. Only found the “fix” a week later on reddit. All of this was after 5 separate attempts to get them to help me over chat and over the phone. I’ve been remaining pretty calm because of the current health crisis and trying not to make a big deal out of this but it’s hands down the worst experience I’ve ever had with Apple and one of the worst customer service experiences I can ever recall having. Being told repeatedly that my own observations are wrong or not accurate is a hell of a way to get me to buy another Apple product.Are you sure it was the same watch, i don’t believe even they can roll back firmware upgrades on watches.

I usually leave mine on the charger overnight ...isn't helpingI was having the same issue on my series 4 a few weeks ago. 5 days in a row where it would randomly shut off overnight despite saying well over 50% before going to bed. It also wouldn't make it through the day and be unresponsive to any button presses. When connecting to the charger, the watch would report over 40% battery life as soon as it powered back on.
Was about to send to apple to investigate when one day I just left the watch on the charger for a lot longer than normal and it fixed itself. Haven't had the issue all month now. My guess is that something in the calibration for battery life is off. To everyone experiencing this issue, try leaving it on the charger for over 3 hours and see if that fixes this for you too.
