How To Make Android Phone, Tablet Run Faster By Deleting Cache Files


Android devices nowadays generally come with 16 or 32GB of internal memory that is shared by all the installed apps on the device as well as your media files. Initially, the storage space might be sufficient, but over time, as you keep on installing and deleting apps, transferring music etc., the free storage space is reduced to an absolute minimum.

Instead of deleting your precious photos or music files, you can simply use an app like Clean Master to delete the cache of all your installed and uninstalled applications and other redundant files to free some precious space on your Android device. If you have not completely formatted your Android device since quite sometime, you can easily gain up to 1GB or more of free space by just using Clean Master.

Think of Clean Master as the CCleaner of Android. The app basically clears the caches of apps, deletes all the junk files left by apps that have been uninstalled and other redundant files to free up the internal memory on your handset.

How To Free Up Space On Your Android Device Using Clean Master

Step 1: Install and start Clean Master from the Play Store on your Android Device.

The first screen that you will be greeted with will be something similar to this -:


Step 2: Select the ‘History’ option and wait for Clean Master to scan your device. This option will scan your Android device for all the cache files created by various apps, including the Android OS itself.


If you do not want to clear the cache of any specific app, de-select it by tapping on the checkbox near its name. This option also clears all the image files that you might have received on Whatsapp.  By default, the Whatsapp images are not cleared. Nevertheless, if you don’t require them, it is recommended to clear them.

Once you have de-selected all the apps whose cache you don’t want to clear, press the ‘Clean’ button on the bottom and wait for Clean Master to do its job.

Step 3: Next, select the ‘Residual Files’ option from the main screen of the app. This option scans the internal memory of your Android device for all the game or app data files left behind by your uninstalled apps or games. For example, most of the high-quality games on Android nowadays require an additional download of 100MB to anywhere up to 2GB after downloading and installing the initial APK from the Play Store.


However, when the game is uninstalled, the data files are not deleted, thus occupying precious space on your Android device. Clean Master will scan your Android device for all these files and then provide you with an option to delete them.

Step 4: Last, but not the least, use the ‘Temp APKs’ option to find out all the APKs files that you may have downloaded from the internet on your device.

Clean Master will categorize the APKs on whether they are installed on your Android device or not. You can now de-select the APKs you want to keep on your device, and delete the rest by tapping the ‘Clean’ button at the bottom.


Clean Master also has an inbuilt Task Killer. However, using Task killers or managers is a strict no-no in Android, and this option should not be used. While Clean Master claims that you can save battery by killing off the unneeded process, this is not the case. Once a task killer in Android kills a background process, the process automatically restarts itself thus consuming precious CPU cycles.
