To each their own, but it sounds like your wife just couldn't get into the "happy path" routine of an Apple Watch user.
I've been using an Apple Watch since Series 5 introduced the always-on display. I wear it for roughly 23 hours a day, and charge it whenever I'm in the bathroom. I'm fine with this routine 99% of the time, but I'm also not someone who'd camp or stay outdoors for more than a night.
Before that, I was using a Amazfit Bip and was really proud of its 30+ day battery life. I very much prefer the features the Apple Watch has.
