How to clear Cache data in Android 9 Pie

The good old caching problem continues in Android 9 Pie. Long gone are the days when you were able to clear the complete cache data piled up in your memory with just a few taps. Now, clearing the cache requires more (and if you ask me, unnecessary) effort.

It all started in Android 8 Oreo, when Google re-modeled the cache-clearing mechanism in Android. Namely, Oreo removed the ability to bulk remove the complete cache data, as you had to go through each app’s settings and clear the cache individually.

Unfortunately, that trend continues with Android 9 Pie. You’re still limited to clearing the cache for each app individually, and that doesn’t seem to change anytime soon. In fact, Google hasn’t made any significant changes to the caching system compared to Android 8.

But, even if your options are limited, I’m going to show you two ways of clearing cached data in Android 9 Pie. Of course, each way has its own compromises, so you can choose which one suits you better.

Clear the cache individually

You can, of course, clear the cache the way it’s meant to be cleared in Android Pie. And that’s by going to each app’s individual settings page and clearing the cached data.

Here’s how to do that:

  1. Go to Settings > Apps & notifications
  2. Tap See all (x) apps
  3. Now, tap the app you want to clear the cache of
  4. Tap on Clear Cache

And that’s pretty much the pattern you have to repeat for each app. There are a few exceptions, like Google Chrome or Spotify, that allow you to clear the cache in-app.

Use Files by Google

Another way to clear the cache in Android 9 Pie is by using the Files by Google app. This is Google’s own app for managing storage space on Android devices. So, technically it’s not even a third-party app. It just doesn’t come pre-installed like some other services.

With Files by Google, clearing the cached data all at once is possible after all. It just requires installing one additional app. But when you look at the effort this app saves you, it’s definitely worth it.

Here’s how to clear the cache in Android 9 Pie using the Files by Google app:

  1. Download Files by Google from the Play Store.
  2. Open the app.
  3. Head over to the Browse section, and tap Apps. 
  4. Tap the three dots, and choose Select all.
  5. Tap the three dots again, and go to Delete junk files.

Files by Google is a great tool for managing the Storage on your phone in General, not just clearing the cache data. It allows you to delete other junk files, duplicate files, unused apps, and more. So, you should definitely take some time to explore this handy app.

That’s about it. As you can see, clearing the cached data in Android Pie requires more effort than it maybe needs to, but you don’t really have a choice. If you have any comments or questions, just write them down below.

After clearing junk files, I chose one of the apps and looked at it from the Android system preferences and it still had caches… Junk data isn’t the same thing as cached data.
