New phone suggestion

I currently have iphone14 pro
It works great with everything im doing now on my phone.

However, if id keep it for an extra 3-4 years, would it be better to change to an new one?

Does android phones last well 4 years for example? Been using iphones since xs release but im willing to swap to android if it can last 4 years up.

If im swapping to a new one, im giving myself a 500 euro budget (is thst enough to ask phone to last 4 years?)
Or do i have to increase my budget? Id rather not..
