How to clear the cache on Android all at once?

Clearing the cache of all apps individually is known to almost every smartphone user. But the majority of them don’t know how to clear the cache on Android all at once. If you are from that user base, follow this guide to learn how to clear the cache on Android all at once in a few clicks. But before knowing how to clear the cache of all apps at once, let’s know what cache is.

What is Cache Data on Android?

Whenever you launch any app or game on your device, your device stores some set of files associated with that app/game temporarily to recall them quickly when you relaunch that app/game ever again. For example, the previews of your videos in your video player app are nothing but cached data of your videos. The video player app generates thumbnails of your videos once and stores them locally, so it doesn’t have to generate them every time you launch the app. Similarly, your web browser stores high-quality images on a website you visit often, so it doesn’t have to download them every time you open the website.

In the same way, every app on your device uses cache data for faster response. So cache data helps your device work faster by reducing the response time of apps/games. However, enormous cache data can eat up your phone’s storage, and outdated cache data can hinder the performance of your phone. That is why I suggest you clear the cache on Android once every few months. But, clearing the cache of all Android apps one by one is a time-consuming process. But, don’t worry, you can clear the cache of all Android apps at once with a single click.
