iPhone 12 Does iPhone Slow Down if Storage Capacity Almost Full?

[Starfyre]

As the topic states, is there any benefit with picking a higher storage capacity iPhone as if you approach the max storage, the phone may start to slow down? What is the threshold/percent that this usually happens? Does this mean higher memory means faster speeds in the long run?

I don’t believe flash type storage suffers from the same issues as mechanical disks for searching and read/write operations, however you typically never want to run any device sub-10% available space if you can avoid it.

I never seen this problem before on a iPhone, Apple uses very good nands (flash memory). Having less GB shouldn't be an issue unless its trying to download an update or app auto update is running.

I have seen some performance issues in situations where you don't have that much free storage. Sometimes it might be because iOS has to perhaps hunt for app caches to clean to make more space or perhaps in relation to something else of that nature. In general I found that you don't really want to have less than 2 GB free, and usually more like 3 even 4 GB. Part of it is also related to being able to update without much of an issue since updates would need to be downloaded and unpacked before/during installation.

Yep, I have a 64gb iPhone and when I have less than 1gb free it performs worse.
