Steps To Detect Caches in iPhone
Step 1: If you turn on iCloud enabled to delete iCloud caches, the next time you will open Safari it will take a long time to load some pages and also force you to log in.
Step 2: Probably your cache is too large and needs a clearing. To speed up your page loading time by keeping just the information that you require and storing the rest of it in the device’s RAM, go to Settings → Safari → Clear Recent History → Delete All or Delete Some Cached Data (you can set a maximum size for caching internet content in Safari).
Step 3: Try disabling Private browsing mode by going to Settings → Safari → Private Browsing Mode.
