I sleep with my watch and use it all day on LTE without my phone, prefer using the AW as my main device, iphone remains turned off/at home.
Some of my use cases every day.
Imessage, check gmail and whatsap notifications, some SIRI, adding calendar appointments, checking crypto stats, record my exercises through STRAVA and have them directly uploaded from the watch, doing payments from the watch.
I charge it daily from 60%~ battery to full in a hour or so at night time before i go to bed.
Sleeping with the watch cost me around ~10% battery life, theatermode on, because i dont want to be disturbed then.
For everyone reading that thinks these results can be achieved with normal usage as intended.
It is not a garmin, and i am not going to turn off AOD, LTE, and lots of features on a 800 dollar watch to gain a few more hours lol, fun for a experiment, but keep in mind you have a 800 dollar casio watch than that tells you the time vs a smart watch.
Some people get a kick out of charging the watch as little as possible but at 800 USD for the AW U and then to turn off a lot of smart watch features, is interesting, i would almost say why not use a casio that runs of a single battery for years and years, even with AOD on
In regards of my battery consumption:
MOST people dont use their AW standalone via LTE every single day like i do, so your battery life expectations per day will be better then mine. But it is perfect now for me compared to my old AW4 LTE.
