I picked the Apple Watch Ultra mainly for the extended battery life. I charge it 15 minutes or so every other day. One of the more useful features I've discovered is it will give you a low battery warning if it detects that you need to charge before bed to maintain overnight power rather than just a fixed percent based warning. That's made it very easy to keep it topped up for tracking my abysmal sleep.
