I put on my $30 watch on Monday, and usually have 30-40% the following Monday when I put it on the charger again for an hour. I’ve developed the habit of charging it during a weekly meeting Zoom call that I have at work.

If you really want a “smartwatch on your wrist”, because you’ve wired up all your home appliances into Apple’s ecosystem or some use case like that, then great. A smartphone’s battery life may be acceptable.

But if your use case includes, “track my heart rate 24 hours a day, my overnight sleeping patterns, and be an alarm clock and practical timepiece”, then paying hundreds of dollars for 18-36 hours of battery doesn’t really make a lot sense against the other options available now.
