How to Clear Cached Data on Android Manually

Is your phone running very slow and you want to boost up its speed? One of the common reasons why Android phones have poor performance is because of their RAM usage. Even if the smartphone has good RAM memory, then too it can face performance issues.

Clear RAM memory on Android

RAM (short for Random Access Memory) is used as temporary storage to save files which are accessed very frequently. It provides fast access to the data. The main purpose of using RAM is to speed up the processing power of the system.

RAM memory is not only used in computers but it is also used in smartphones today. If we talk about Android phones particularly, there are several ways in which RAM memory is utilized. The apps and the Android system itself uses RAM memory to save cached data on your phone.

Unfortunately, the cached data is not cleaned up automatically after its use. As a result, RAM memory fills up with a lot of unused data and then it causes your phone to lag. To fix this issue, you just need to free up some space on your Android phone and then you are good to go. Let’s see how to do this!

How to clear cached data on Android

There is a feature in your phone settings where you can check your RAM usage and clear unused cached data. Follow this step-by-step guide –

  1. Open the Settings app on your Android phone.
  2. Find and open the Memory option. In Samsung smartphones, this option is available in Device Care settings. Simply, click the Device Care option and then click Memory.
