Yeah, I'm writing this on an s10e but the battery really isn't that good anymore and the lack of security updates doesn't feel good either. The current s series phones are roughly the same size as the e though, so I hope it'll be okay.

That said, even the e is a bit too large for my taste. The top left corner is pretty much out of reach without adjusting your grip, so about half an inch less of screen would be preferable imho. Samsung's one handed mode is much better than the android default though, which kind of makes up for it - and there's just nothing smaller available.
