I think it’s pretty worth it considering XS Max is still blazing fast for everyday usage even by today standard.

I too recently bought a used XS Max from Compasia and it’s absolutely mint. But the battery health is at 80% and i am gonna replace the battery later on this week at Switch.

If you ever want to upgrade to a newer iphone, I’d suggest you to wait a little longer for iPhone 15 series this year as it’s pretty much confirmed that Apple will start using USB-C in all of their iPhone lineup, just that the normal (non-pro) will be gimped to USB 2.0 speed (same as current lightning).
