I had a hard time choosing the right Apple Watch and while waiting I ordered an amazfit bip. The difference in battery-life was unreal, Even with constant HR and everything enabled plus it had always on display it used less power per day, than AW in 1 hour. I don't think I charged it more than once, the weeks I had it, before giving it to my father.As much as I like my other Apple gear, I cannot bring myself to get the watch for this reason. I don’t want to have to charge it every day.
My Garmin Forerunner is worn 24/7, recording steps, heart rate, sleep, etc plus a couple of runs using gps and still lasts a week.
Wonder if there’s any chance of Apple getting at least 3 days battery life, then I might be interested.
A couple of other thoughts here. How long have you had the watch or how long has it been since the last update was applied? I ask because typically it takes a few days for the watch or any Apple device to "settle down" to a point where battery life is normalized.
Have you installed any apps recently? Rogue apps are often a source of battery drain.
Lastly, this is a good read to walk through your settings.
