Phone Rec
I like my phone and it fits in girlpockets. I don't have a user replaceable battery, but the firmware does do some battery capacity protection. I use a Samsung Galaxy ZFlip 5G. I've had it for about a year ish and like it reasonably, though it took some work to get it less 'noisy'.

@BestGirlGrace (the hinge is a flexible part of the screen. There is a hardware thing that's like a little wide block that prevents it from closing and 'creasing' super duper flat. You can feel it, but it doesn't get in the way. The folding bit is great for selfies since you don't need a stand.)
