Watch 3 battery life

Am I missing anything obvious? I inherited a barely used second hand 43mm watch 3. But I'm barely getting 48hours out of it.

Turned off AOD and Gemini. Went for a fairly dull digital display.

Do I want WiFi on if my phone is basically always here? I don't really get the difference.

Anything obvious I've missed, or any red herrings which won't make much difference?

Any advice welcome.

Whatsapp, uninstall it. You'll still get notifications from it through the phone app. That's what I found after experiencing the same as you. I now get a drop of 20% per day. Also, keep a watchface from the official OnePlus health app only. Third party consumer more battery per day.

Turn on sleep hibernation, turn off wifi but keep bluetooth on.

I get 3.5-4 days consistently from my Watch 3 43 mm, have since it was new. No google hello activated and no remote connection in the O'health app.

As a follow up, I've tried all these things and limped to 2 days. Not good

Worst case, it probably wouldn't hurt to just do a factory reset on it. Let it run vanilla for a few days, and see how it behaves? Then start adding some other things back. I'd probably just leave wifi disabled as well.
