How to clear Android cache

Android phones thrive on RAM (Random Access Memory) to keep your phone running fast. When you keep loading more apps and data into the storage, the temporary memory of the system gets loaded.

This usually occurs when we run heavy apps or use the same app for longer periods. This clutter feeling of the UI is the result of an overloaded memory. To solve this problem, we must clear cache frequently to keep RAM available for the apps being used. So, learn how to clear cache in Android all at once for a faster performance.

What is Android cache?

There are three ways Android cache is generated.

  • Storage cache
  • Browser cache
  • System cache

All the cache related to UI becomes System Cache including the load on operating system. Usage of Internet browsers like Chrome, Mozilla will create Browser cache and all apps like Facebook, Instagram and Amazon have their own app cache databases.

The overload from all the caches slows the phone and leads to crashing. So, it is necessary to clear Android Cache manually everyday to keep the phone uncluttered.

Note: Cache are data files stored by apps to serve future requests faster. Deleting temporary cache will not delete important system files. Clearing cache will only free up space for currently running apps.

How to clear cache in Android for faster performance

To remove all types of cache, there are third party apps like cCleaner, clear cache and more. But there is also a manual method to clear cache from the system. Let us explore how to clear Android cache through different methods.

1) Clear storage cache with File Manager

Storage cache is formed from the thumbnails, deleted files and app cache. More cache keeps forming as we store more files on both internal and external storage. Storage cache slows down the storage disk of the system making it difficult for RAM to fetch for apps. This will slow down the phone. Clearing storage cache will ensure your storage disk is running efficiently and serving files.

In order to access storage files we need a File explorer. If you are using an MI, Oppo, One Plus etc., there is a file explorer available. We can see which files are creating cache and clear them manually via File explorer. To clear storage cache in Android,

  1. Open default File Explorer in your Android device. (Install File Manager if you don’t have one)
  2. Choose Internal or External storage and go to Files.
  3. Open the Storage section to see which files are taking up the most storage.
  4. Go to Cache section and check all Cache files.
  5. Hit ‘Clear cache‘ to empty the cache folder.

This will delete all temporary cache files that are stored on the server. By doing this, you have freed almost 10% of storage space on your disk. By clearing the storage cache frequently, we keep the storage disk running smooth.

2) Clear App Cache with Browsers, Cache cleaner

App Cache is the useless information stored by apps to use for future references. Even though app cache is helpful in loading the page faster, the cache soon piles up. This makes the app and browsers slow making the phone crash. To clear this problem, we need to clear all types of app cache from the device.

App cache forms through Internet browsers and Media apps. All the webpage cache are loaded from Chrome and media thumbnails from other apps. As there is no way to clear app data manually, we must do so from third party apps. To clear App cache in Android,

Clear App Data and Cache from App Settings in Android
  1. Open Settings>Apps.
  2. In Apps, click on the specific app that is creating a lot of cache.
  3. Navigate to app options and click ‘Clear Data‘.
  4. This will clear the temporary cache of the app.
  5. Go back to apps list and clear data for first 5-6 apps.

How to clear cache in Chrome browser?

Chrome and other Internet browser keep generating cache as we surf more pages. As browsers use a huge amount of RAM from device, it is important to clear Browser cache at least once a day to browse efficiently. To clear Chrome cache in Android,

  1. Open Google Chrome>Tap on settings tab on the top right corner.
  2. Click Settings.
  3. Navigate to Privacy and Security.
  4. Choose ‘Clear browsing data‘ and select ‘Cached images and Files’.
  5. Tap on clear data to clear all cache.

You will notice options for Browsing history and Cookies clearance. Both of them doesn’t slow Chrome, but it is recommended to clear these too. You can also use the same process in different browsers to clear cached files.

3) Clear System cache with Boot Recovery (Advanced)

System cache is the data from OS that is being stored to make the UI faster. But as we keep using the device, the system cache keeps growing. All apps also leave their cache on system letting access to duplicate files. By deleting these multiple cache files, we clear space for the UI to load more efficiently.

Even after we clear system cache, all apps rebuild their cache databases. So in a way, there is no use of clearing System cache frequently. But if you are using an old device that has a history of too many apps, clearing system cache will ensure your device runs cache of only currently installed apps.

All system app cache is stored in data/app directory. This folder isn’t accessible via File manager or cache cleaner. So, we use Boot recovery and Wipe cache partition to clear system cache in Android manually.

Click ‘Wipe cache partition’ to delete System cache in Android
  1. Switch off your Android device by holding the power button.
  2. Switch on the device and keep pressing Volume Up+Power+Volume Down buttons to boot into recovery mode.
  3. In the Menu, you will see different recovery options.
  4. Navigate with volume buttons and select ‘Wipe cache partition‘.
  5. Select with power button to start partition.
  6. Wait for 100-120 seconds to let the partition finish.
  7. Turn off your device and switch it ON in normal mode.

By clearing the system cache this way, you are wiping off the hidden cache from the OS. Now the system will only create cache for apps that are being used.

By following these 3 simple steps, you will be clearing Storage cache, App data and system cache in Android. This will free up a lot of RAM for apps to run smoothly. Clearing cache is an important process of maintaining an Android device.

If your device is running slow even after clearing cache, it is time that you delete some heavy apps that are taking up a lot of RAM. As phones get older, the more they hang. So, keep your device uncluttered from cache and opt for faster performance by following the above tips.
