Running my first half-marathon next month. I’m worried my four-year-old Apple Watch SE at 72% battery won’t last the entire run.

I considered the Ultra 3, but two Apple Watch SE 3s are a better deal. Their combined battery life is 2×18 = 36 hours, which is less than the 42 hours of the Ultra. The benefit is that one can stay on the charger while the other is in use. Plus, two of them are significantly cheaper than the Ultra.

The likely decision will be to run fast and save all the money. 😆

@mkj Sorry if you have been through this discussion before, but for sports I can really recommend the Garmin watches. Even my small Garmin watch without solar charging will easily last a week with several activities in it. Not having to care about battery life is great, I can easily squeeze a 10 K run from the watch even on the last 20 % or so.
@zoul Yeah, I just need to do the mental switch one day…
