I have a Sony Xperia 10 III with SailfishOS and it easily does 48 hours on a charge when I'm not doing a lot of screen time. Also on days when I use it for tracking / navigation on 6-8 hour bicycle rides it easily lasts for the entire day and then some. I think this is not bad for a device that has been in daily use for almost three years and still has the original battery.

I'm running a couple of messenger clients and a web browser (Fennec under Android App Support as the native one is sadly a bit behind the times currently) all the time. The only thing I've noticed to eat a ton of battery is having wifi enabled when outside the range of my own networks, it seems the scanning the phone does in the background to look for known wifi networks is not energy efficient at all.

I also have this setup and SFos on Gigaset GS5. Similar battery performance. I did a roadtrip last week with navigation (starting with about 90% battery) and after 5&1/2 hours navigation was down to 65% or therabouts. Works for me.

And, yes, I often turn off wifi. I never go over my Data limits and 4G/5G is much more efficient for some reason.
