The term “cache” is heard very frequently. Cache is basically¬†a component that transparently stores data so that future requests for that data can be served faster. The data that is stored within a cache might be values that have been computed earlier or duplicates of original values that are stored elsewhere. If requested data is contained in the cache, this request can be served by simply reading the cache, which is comparatively faster. In short, cache will help in loading the data faster.

Jelly Bean 4.2

However, if the size of the cached data increases too much, then it can significantly slow down the system. So it becomes imperative that the cached data is cleared from time to time. In the Android versions before Jelly Bean 4.2, the user had to clear the cache of every app manually. This is a very tedious activity. But in the Android Jelly Bean 4.2, there is an inbuilt feature using which an individual can delete all the cached data at once. This allows the user to clear the cache without using any app.

Just follow the instruction given below to delete the cache of all the apps with just a single tap.


  1. The Android user will have to first go to Settings.
  2. Then scroll down and find the “Storage” option.
  3. Now the following screen will appear.
    Settings cache
  4. Tap on the “Cached data” option.
  5. Now the following prompt will appear on the screen.
    Cache Option
  6. Just click “OK”. After a few moments, the cache will be deleted.

After clearing the cache, the user will experience that the Android device is much faster. It must be noted that this feature is available only on Android Jelly Bean 4.2.
