How can I creat a new Apple ID the one i have already created too many and now I want to creat a new one but it’s not working I need help please

Creating new Apple IDs will not speed your device, nor have any effect other than scattering any email and contents and app purchases associated with those new Apple IDs around, and where those email messages and purchases and subscriptions cannot ever be transferred to nor consolidated to one Apple ID.

In short, creating Apple IDs is not helpful to “make my phone fast”, amd may well be detrimental.

Just. Don’t.

Which iPhone, and what’s happening with it?

An iPhone that’s filled to capacity, or that’s getting older, will be slow.
