The new Apple Watch 10 has an 18-hour battery life, so if you use it while you sleep, you won't have much left.

I have no idea how some people can charge their smartwatch 1 or more times a day.

It is a non-issue for me with the Apple Watch 9. It's charged super quick e.g. if the battery is low after waking up you can plug it in do your morning routine and pick it up. Vice versa in the evening before going to sleep.

Also did some bike packing this year and charging it with a power bank was also not an issue. At one point my power bank was empty and my apple watch ran out of power as well - this has been the only time I whined for more battery life.

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.

I keep the charger plugged into my computer. I slap the watch onto the charger every morning as I drink my coffee and read my e-mails/news. It's... not difficult to imagine...

I find that integrating it into my routine made my current watch (SE1) battery a non-issue. I wear it starting in the morning, charge it on the way to work, and then to bed. Repeat ad infinitum. Battery usage at night is way lower in my experience, and it usually survives til morning or close to it.

I can only speak for my S7 but with the fast charging mode it doesn't take long. My routine is I wake up, take off my watch, scan my phone for a bit, and take a shower. Almost every day it's fully charged by that point.

The S9 was 80% in 45 minutes. The S10 is now 30 minutes.

A nice jump but not earth shattering.

I used to charge my watch every time I took a shower, which was every morning. Never had to think about battery life or charging the watch "out of band". But then again, it wasn't an Apple Watch.

People probably use it principally as a fitness (and sleep?) tracker, and charge it while they work

I mean it's still a watch so hopefully people are going to use it as a watch.
