What's the absolutely maximum battery life you get with an Apple Watch when disabling bluetooth, notifications, GPS tracking, etc.?

It's the battery life that keeps me from buying the watch, but maybe the latest watch offers more juice as well.

Only need GPS for an occasional run.

Oh, and heart rate and sleep tracking is essential for me, so those shall be on nonstop.

Appreciate your user feedback, thanks ahead!
 
Isn’t Bluetooth used to keep the watch and iPhone paired? If so, disabling Bluetooth is a bad idea.
 
Disabling all the features would be stupid. You might as well get a non-smart watch then.

If 1-2 days between charging is a big deal for you, the Apple Watch isn’t for you. Full stop.

It’s really not an issue. Slap the thing on the charger before bed. Done. Want to sleep with it for tracking? Fine, put it on the charger while you are in the shower or some other relatively short amount of time. Good enough.

I have owned an Apple Watch since launch. Battery life has only been an issue or a thing I even tracked one time. On a 100 mile bike ride workout tracking couldn’t last for 6 hours.
 
Apple watch series 3 42mm here at the moment. With everything on, push email, all background apps, bluetooth and wifi I can easily wear it for 2 days straight without a charge. That includes some workouts.

Battery life is way higher than the 18 hours apple say.

If your going to turn everything off then dont bother getting it.

So I’m assuming battery life is better on the bigger models, even with the screen itself being bigger?
 
I'm gonna go out on a limb here and make a guess at your question; although echoing other commenters here on the usefulness of the watch with features turned off to begin with.

I don't own a watch yet, but based on the battery capacity, and average battery life, I would assume it would last 3 days with minimal/very low screen time usage.

Turning off raise to wake will make a big difference in battery, so if you didn't want to use that feature that could make a real difference. Turning down the brightness can also help. You say you want HR tracking on all the time. The key is that means one of two things, if you are running a workout, HR is running continuously, and that will kill the battery. There is a setting to turn that option off for workouts. Otherwise, yes HR is running all the time, but it only takes readings periodically and shouldn't really kill the battery.

But you should get 2 days easily without any changes and using it all you want. So I would do the above tricks if I was trying to get 3-5 days for some reason.
 
We'd get around 2 days on the S3 38mm and 40mm's and that's with notifications and a constant BT pairing. You could probably stretch it out into day 4 if you didn't use any functions and went into airplane mode.
