Cache is a term referred to data that is downloaded from the internet to your device so particular apps will run faster and save some data plan as it doesn’t have to re-download the same content. It may even allow the apps to operate offline.
It’s a beautiful mechanism is all around us, and it’s without a doubt, pretty handy. But of course, built-up cache taking some valuable space on your phone and in the long term could hurt its performance. That’s why it’s a good thing to clear cache once in a while.
You don’t have to purge all the apps cache, rather just focus on the ones contributing the most. And here’s how to clear the app’s cache on Android.
The following guide is based on the Android 9 Go Edition. But it goes without saying that the interface should look comparable to other Android versions.
1. Go to Android’s app menu.

2. Tap and hold an app and select App Info. Sometimes it’s only represented by the ( i ) icon.

3. Now head to Storage.

4. You would see the total cache size of the app and a button to Clear Cache.

5. Cache will be cleared.

Clearing cache is neither dangerous nor affecting the functions of the app. But after purging the cache, you may notice a slight slowdown during the startup. This is perfectly normal and the app will be getting faster to load over time as it’s rebuilding new cache data.
From a practical standpoint, you only need to clear cache if the app feels unresponsive and laggy or if there’s a problem within the app. However, if everything seems fine and there is no concern over the cache consuming storage space, then it’s okay to not deleting the cache.
