Fresh install on phone OS?

[Gamer Schnitzel]

As many people here I always do a clean install of Windows when I update the OS.

 

My question is whether on phones the same logic can be applied?

Will there be less junk files remaining internally if I do a factory reset after updating to the next level of the OS?

It is going from iOS 15 to 16.

I have not touched my Windows 10 install from the day I installed it to the day I sold my computer, about 6 years. Fresh installs for what reason?

It would make everything more inconvenient for you as you'd have to run through setup again. Other than that uh... no I don't think it does anything. You're just reinstalling from the same image anyways, the only reason to do a clean install would be if that image were corrupted, in which case you'd use DFU mode + USB cable + iTunes, not the device itself.

There's no practical benefit to starting clean. Strictly anecdotally, I've never reset my phone for an OS upgrade (Android or IOS) and haven't had problems.
