What is cache data on my phone?

Over time, when using your phone, the installed apps store bits of information to speed up the user experience.

The cache is a temporary storage file used by websites as well as applications to store some data on your device.

It contains references like where to store the settings or in which folder it should load or store the source file, as well as thumbnails of the images that are to be displayed in the application.

Advantages and disadvantages of cache memory

What is the purpose of cache files? Once you have already loaded a website or an application on your phone, thanks to the data stored in the cache file, it will load exceptionally fast when compared to the first time load.

For instance, when you’re using a web browser, it will save images you’ve seen so that they don’t need to be downloaded again and every single time the app needs them. Spotify stores streamed music in its cache file for faster (and offline) playback. This saves you time and data. It is the main advantage of the cache.

Every application has its own cache file and clearing that cache is a great way to free up space. Just keep in mind that the app will rebuild the cache as you use it, so clearing cache data on Android is just a temporary fix to get extra usable space on your device.

The downside is that over time, your phone is going to collect a lot of files you don’t really need and can take up to some gigabytes of usable storage space.

Is Android cache cleaner necessary?

As well as the first time you load each app after the cache cleaning procedure.

You may also note some increase in mobile data usage, for instance when using apps as Facebook or Spotify. Like thumbnails and music you may have listened to previously are going to be downloaded again to your device.
