Every time you use an app or browse sites online, your Android phone builds up a collection of small files in the background called a cache. That's how apps and websites load images, scripts and page elements faster the next time you open them, instead of downloading the same data over and over again.
It's a lot more convenient for the apps and browsers to pull data from storage, of course, but that convenience has a cost as the files start piling up, turning into a storage drain. Over time, this can lead to your phone feeling more sluggish or with you unable to install new apps because you're running out of space.
The immediate benefit of clearing your cache is the fact that you'll free up storage space and improve your device's performance. Let's be clear: clearing the cache won't fix every performance issue your phone has, but it's a safe and low-effort move that will make your Android phone a bit speedier.
Clearing the cache on your device is one of the safer maintenance tasks you can perform on an Android device. Before getting into it, however, it helps to know exactly what changes and what stays the same. Clearing your cache is always a good idea if your phone is slower than it used to be or apps take longer than usual to open. It's also a good step to take if you want to clear up some storage space or if specific apps are crashing, freezing or behaving inconsistently.
