Love my Apple Watch! Its main downside compared to the rest is weak battery life, you basically need to charge it every day. It’s an easy habit to form though (I just throw mine on the charger when I shower).
Mine lasts about 3 days before I have to charge it, but I’m also largely ignoring it and use it as a watch / timer / notification reader. I had one with the cell modem but when I broke it was during the pandemic and just wasn’t on-site where I’d often leave my phone at the desk.
My battery health has gotten awful recently too. I’ve got a series 5, so yes it’s 4 years old, but I genuinely only get about 12 hours of battery life these days. I went through and uninstalled every single app I don’t use, but it’s still awful.
Love everything else about it though, so I set a slickdeals alert to hopefully pick up a cheaper series 8 sometime between now and when the series 9 launches
