Hello guys! I got something that questioned me long time ago and I want to ask you if it is real or not? I got my iPhone 7 Plus this January and installed tons of Beta Software and also reverted to stable versions, so that means a lot of GBs have been written and deleted from the iPhone memory...
So now I want to ask you, is there any possibility this will affect the iPhone memory (storage one) in some bad way? I might compare it to an SSD who has a limited number of data written...

As far as I know, this happens only to SSDs and Android Phones! :-D

Let me check the storage memory on my 2011 iPhone 4s 8GB and my 2012 iPhone 5 64GB and get back to you!

EDIT: Both phones, way older than yours performing flawlessly.

Looks like you don't have anything to worry about.

TLC NAND is typically rated at 1000 P/E cycles. With 32GB storage, it's good for 32TB NAND writes minimum. The 256GB model? It's 256TB NAND writes. Granted, write amplification means less OS writes but really not something to worry about.

Circa 2010, iPhones were probably using MLC NAND with 5000 P/E cycles so a 16GB model is good for 80TB NAND writes.
