A57 vs s25fe vs s25

Hello, I'm upgrading my phone and I need to choose between these three. I'm very confused cause all are good for the average user. The things I prioritise are a decent camera to take pictures of my drawings and post and for reference photos and the battery life as I use whatsapp a lot and calls. I also don't want to have to change my phone after 2-3y, I want it to last 4-5 if possible.

I don't know which one to choose cause most are good for this and I saw that while s25 battery is smaller it ends up lasting the same as the others as it has a better processor. But I don't know over the years what happens with deterioration.

After the discount from trading my old phone s25 is $470, s25fe $396, A57 $175
