How to Delete app cache, cookies and temp files from iPhone

If you want to speed up your iPhone,you can clear app cache, cookies and temp files from iOS devices,or delete those unwant photos on iPhone permanently.

This article mainly teach you how to remove Apps Caches from iPhone permanently,so that speed up your slow iPhone.

Apps on mobile devices tend to occupy a lot of space over time. With every bit of use, these apps accumulate huge chunks of data, some of which become useless (junk) as time goes by. But it’s not recommended to keep them (app cache, cookies, temporary files, log files, etc.) on mobile devices because of their limited storage, especially when the available space tends to be low.

How to erase junk files from iPhone

On iOS, junk files are cleaned up automatically when the device nears its storage limit. However, you might want to clean up these files manually for maintenance purposes. Here are a few tips that will help you to remove unnecessary app data without jailbreaking your iOS device, and thus, free storage space on iPhone and other iOS devices.

Apps accumulate a lot of data over the course of time with usage. This data can be regarded as non-critical, since it can be easily regenerated. However, this data also includes files that store unsaved progress in apps. Deleting such files may thus remove any unsaved tasks from your device.

Such data may be classified into four broad categories:

Cache: Apps often store data locally from where it can be quickly fetched. This locally stored data is known as cache. Data which is not present in cache need to be read from the original source, which usually takes longer compared to accessing data from the cache. Cache files help to improve app performance, but occupy a considerable part of the device storage over time.

Cookies: A cookie is a piece of data stored on your device that helps to maintain the app state and its connection with the server. Cookies store information about your login, preferences and other personal data. They also help maintain the user sessions within apps.

Error Logs: In the event of an app crash or an error, logs are created that record the incident. These logs may be helpful to developers for debugging purposes to find out the cause of the crash event.

Temp Files: Apps create temporary files during their operation. These files are rarely used afterwards and some of them remain on your device.

Clean up junk data from app settings

Some apps on iOS allow you to perform clean up of app cache, cookies, temporary files, etc.  For example, most web browsers for iOS have the option to clear cache and cookies in the respective app settings. If you want to know how to clean up cache and cookies from popular iOS web browsers, check out this page. Some other apps also provide similar clean up options. But you need to manually check them since the availability and position of such options varies among different apps.

Clean up junk using memory management apps

With the new version of iOS, it is now possible for apps to access and clean cache and temporary files belonging to other apps. This allows developers to create apps for memory management, which can clear data from apps, much like the ones found on Android. The latest version of Battery Doctor is one such app which takes advantage of cache memory access to clean unwanted junk files from your iOS device (eg. iPhone, iPad).

Clear App Data using iTunes

One of the easier ways to clear an app’s “Documents & Data”, is to uninstall the particular app and then re-install it again. The freshly installed app won’t contain any additional (junk) data. You can uninstall and re-install apps from your device itself, but doing so from iTunes saves you the trouble of re-downloading them, if offline backup is available.
