Apple

Idk I’m of the mindset I’ll use a phone till it doesn’t work anymore or stops having iOS updates. Hence why i only switched from my 8 plus to the 15PM a month ago lol

Dynamic Island and 5x optical zoom are about the only differences you’ll notice. Keep your 13 pro max, its an excellent device still.

Not worth it.

I went from a 13P to 15P (not max). My little brother needed a iPhone, so I “upgraded” to a 15P and gave him my 13p, if it wasn’t for him I would’ve never upgraded. Day to day usage, I notice zero difference in speed, signal, or battery life, at times I forget I’m even using a new device until I see the Dynamic Island pop ups or I need to use the new action button to mute my phone.
With that being said, I noticed a bigger difference when I went from a 12P to 13P. The 13 Pro is a great phone

I wouldn’t do it
