u/Character-System-517

For some context, my mom recently got the iphone 17 pro max and gave me her iphone 13 pro max(I’m currently using the iphone 11). However, I was looking into reselling it to an iphone 15 or even an iphone 15 pro. This is more due to storage and some screen issues the 13 has that bothers me, the 13 also has 74% battery health. So I want to know if going to the 15 is going to be an upgrade for my case and stuff.
Thank you in advance!
