What is Android cache?

Android cache is a collection of data stored on your device. It can include app data, images, videos, scripts, visited websites, and much more. It’s all about loading apps and websites faster when you use them again. For example, an image-heavy page will load much quicker if it pulls the images from your cache.

Your Android phone or other device has three separate caches:

  • App cache: The app cache contains temporary files, images, and scripts from downloaded apps. Clearing the app cache will speed up your apps and improve their overall performance.
  • Browser cache: Whenever you visit a website, your browser stores some bulkier elements, such as images.
  • System cache: Android OS also has its separate cache. Clearing this data can improve performance, free up storage space, and fix some app problems.

Why would you clear your Android cache?

Data caching can ensure better performance up to a point. If you let it build up, it can actually slow you down and even cause security concerns.

So, let’s go over some of the benefits of clearing your Android cache:

  • Improving performance: When your cache gets too full, Android has to sift through a lot of files to find what it needs. Outdated temporary files can cause conflicts and crash your apps or browser. Clearing your cache essentially declutters your OS.
  • Freeing up storage space: Deleting unnecessary data will free up space for more important files and apps.
  • Improving stability: As mentioned, some of the cached files can become outdated or corrupt. When this happens, you’ll experience app crashes, browser glitches, and other unpleasant anomalies. Clearing the cache will prevent this.
  • Boosting your privacy and security: Sometimes hackers exploit cached data to launch a cyberattack. Clearing the cache of outdated and exploitable files can help protect your Android device.

Clearing app cache

On an Android, you can’t clear the cache for all apps in a single step; you have to do it individually. Going through each app's cache could become tedious. However, if you’re facing problems with a specific app, it can help troubleshoot the issue.

Each manufacturer will have slightly different processes for deleting app caches. The general process, however, looks like this:

1. Open Settings

2. Tap Apps

3. A list of installed apps will appear. Select the app you want to clear.

4. Select Storage

5. Choose Clear cache to delete the app cache

Storage Tab

What happens if you don’t clear your Android cache?

Not clearing your cache could result in a lack of available storage and sluggish performance. However, there are also some privacy and security concerns to worry about:

  • Exposure of personal info: Android cache contains data like your browsing history, login credentials, and more. Hackers can steal and exploit this info with malware.
  • Tracking and profiling: If someone steals your sensitive data, they can sell it to third parties. Marketers and malicious actors can then track and profile you based on your habits.
  • Accumulation of malware: Android devices can cache malicious software and scripts, which can compromise them and create a backdoor for malware attacks.

We’ve already mentioned vulnerabilities caused by outdated and corrupt cache data. Clearing your cache is an excellent first step, but staying safe online requires reliable tools.

A good VPN (virtual private network) is one of the essentials. It masks your real IP address and encrypts your entire traffic. With such protection, hackers won’t know who you are and won’t see your online traffic.
