How to Wipe the System Cache Partition on Android Devices

I use many different apps and websites on my Android device; they range from SoundCloud to others used for catching up on news, and others for gaming with my friends. So when an often-used app encounters issues it can be really frustrating.

If you have issues with an app on your device, wiping the data cache could be the quickest and easiest way to solve your problems while improving your phone’s performance in the long-term.
If you want to find out what the system cache is, what it does, and a few different methods for how to clear the data, check out the following guide for everything you need to know.

What does the System Cache do?

It sounds complicated, so let’s try to keep it simple. The system cache is found on every Android device.

The Android OS uses partitions to organize files and folders on your device, and one of these partitions is the system cache. This partition stores temporary system data for everyday tasks. These ‘temporary’ files are the images, text, and videos that are used to display things like web pages and adverts. They help to load things quickly when you revisit web pages or load your favorite apps.

The temporary files in the system cache are used for faster access when using apps (which can be useful if you’re constantly playing Clash of Clans or Candy Crush like most people I know). But these files can sometimes lead to problems when the settings become outdated, or if your device or a specific app starts to encounter general issues.

One solution to help is to wipe the system cache partition data. There’s no such thing as “too much clearing”, so you can wipe the device as many times as you want without causing any issues. It helps to keep apps running smoothly, and it’s recommended after a system update to keep your phone optimized. It also helps to free up some extra memory space. (But normally it’s not much as the files shouldn’t be too large.)

When you load up the app or web page for the first time after clearing the cache, it might take a little longer to start up, but your device will save new temporary files that are more relevant to your recent usage.

How to Wipe the Cache Partition:
Now we know what it is, how exactly do we clear the Android system cache? It’s pretty easy, and there are a few methods to choose from, which should take around a minute to complete if all goes to plan.

The first and second methods listed will clear all cache files on your device. The third method in this list details how to clear cache data for individual applications if you want to keep some of your files, so the choice is yours.

(These methods will not erase any personal data or settings on the device, just the temporary cache files.)

It might seem like a hassle, but it can’t hurt to wipe the system cache partition from time to time. It might not clear up much space on your device, but it helps to keep everything running as smoothly as possible, and it’s harmless.

The extra memory will probably be nominal, but what’s the point of keeping data for forgotten apps and old web pages that you’re never likely to visit again, when it could be used for more important things, like a great puzzle game, or a few more episodes of your favorite show?

    When I cleared it from settings it completely removed the cached data from my phone. Is that normal?

      Hi Rachelle,
      System cache? Where was the option to do that in settings?
      Or do you mean simply app cache?
      Either way, no worries. Everything should be fine. =-)
