The iPhone 7 on Amazon (paid link) stopped receiving software updates years ago, so you will be stuck on its last version soon. Apple sells the iPhone Duo (paid link) today for $1999 as a brand-new foldable that lasts days on a charge where the 7 is already spent. You pay a massive premium for modern features, but there is no upgrade path from a legacy device that Apple no longer supports. If you want a modern iPhone without the foldable price, the iPhone 16e (paid link) is a far cheaper option.
