What is the cached data in Mobile

Android: This trick helps with app problems on the smartphone

If apps are not working properly or you need storage space on your smartphone quickly, clearing the cache can help. We explain how to do this here.

Many devices create a buffer, the so-called cache. This applies to computers, browsers and also to apps on Android smartphones. A cache grows over time and can therefore occupy large amounts of data. We explain what exactly the cache does and when you should clear it.

What is the cache?

Apps on Android cache data for faster access. For example, game apps or browsers can save graphics and other elements to make them load faster.

Android knows two caches: One is used by apps, the other by the operating system itself. This is the so-called Dalvik cache. This is where Android saves information about installed apps on the device.

When should I clear the cache?

Apps usually decide for themselves how long to store data. Unnecessary information is deleted or replaced. Sometimes problems can arise here, however, and the app concerned reports startup problems. It is also possible that an app cannot load the current version of a page. In addition, sensitive login information can be stored in the cache - like that of a browser.

If you have problems with apps, you can clear the cache of apps. This also releases a large amount of data at the same time. Note, however, that Android will refill the cache over time. Cache deletion is no solution for permanently more memory.

How can I clear the cache?

You can either clear the cache of individual apps or all of the cached data at once. To do this, proceed as follows:

Clear cache for individual app (Android 6.0 and Android 9.0):

  1. Open the Settings.
  2. Are you looking for "Apps"or"Applications".
  3. Now all installed apps should open. If this is not the case, click on "Application manager"
  4. Select the app whose cache you want to clear.
  5. Click on "clear cache". If this is not displayed, click on"Storage"and then on"clear cache".

Clear all apps cache

  1. In Android 6.0, open the Settings.
  2. Click here on "Storage"then on"Device memory".
  3. Click below on "Cached data". The system now offers you to delete all cached data.

As of Android 9.0, it is no longer possible to clear the cache of all apps at once. The device may offer you the option of cleaning up the memory. Cached data is also deleted in the process. This is the case with Samsung devices. To do this, proceed as follows:

  1. Open the settings.
  2. Click on "Device maintenance" and then "Storage".
  3. Click here on "Clean up".
