> With the Apple Watch, I would be uncomfortable starting a dive with less than 80% battery... You'd get over that quickly if you owned this watch. It stays above 80% all the time, with just a few minutes on a mag charge in AM, while you're showering for example, and a few minutes in the evening (during a TV show or video game, for example), even when using it all day for work notifications and all night as a sleep monitor. It goes 2 or 3 days without charge, and that's before their software update to get a multiple of that. Assuming a 30W+ charger brick, it's surprising how quickly it tops back to 80% ready to go another day or two. Workout mode doesn't burn much more, neither does dive. Your other takes could improve with actual use as well. Nitrox and gas config, for example, is on the 2nd to last and last screenshots of the watch app itself.
