Before I go to show how to clear app cache iPhone, let me first explain what App Cache is.

For the sake of enhancing user experience, every time we use an App on our iPhone or iPad, it collects information and stores it in a reserved memory space called Cache. This stored information can be retrieved quickly from the cache for future use. For example, Safari uses a cache to store information about the sites you visited, and will use them later on in order to speed up your browsing experience. Even though this is crucial when it comes to making the site faster, these cache files generated through everyday usage are eating up your iPhone storage as time progresses and reduce the running speed and efficiency of your device. Cached browsing data aren’t the only files that eat up your iPhone’s storage space. Cache data could also be scripts, images and other media files that are automatically generated by the apps. Increase in number of installed apps with time and increase in frequency of use of apps, may cause accumulation of more cache files resulting in use of additional storage space of your iPhone making the device slower. No matter which iPhone you use, regular deleting cookies, hidden junk files and clearing other iPhone app caches are not only a great way to make your iPhone clean and to free up more space but also to boost its running speed.

Apps are encouraged to use as little memory as possible so that the system may keep more apps in memory or dedicate more memory to important apps that truly need it. There is a direct correlation between the amount of free memory available to the system and the relative performance of your app. To ensure there is always enough free memory available, you should minimize your app’s memory usage and be responsive when the system asks you to free up memory. When the system dispatches a low-memory warning to your app, respond immediately. Low-memory warnings are your opportunity to remove references to objects that you do not need. Use the warnings to clear out app caches and release images.
