How to Clear Your Browser's Cache on an iPhone
As you browse the internet on your iPhone, your browser will store bits of information about each site you visit to speed up loading when you return. While this can be great for quickly loading pages, your cache can start to eat up your iPhone's free space. Thankfully, all browsers allow you to quickly clear your cache, freeing that space back up.
