Clearing cache: What does it do and is it safe?

android clear cache - Clearing cache: What does it do and is it safe?

One of the most common solutions to recoup those lost GBs is clearing the cache of your device. While it does work, it is important to know what it does and how safe it is to do it.

Let’s imagine this situation: you are scrolling down your Twitter feed. The app displays the profile picture of each account, consuming data in order to download it and show it to you. What happens if someone tweets again and the app needs to retrieve the appropriate profile picture? Downloading the picture again would be a massive waste of time and data.

This is where the app cache comes in. When the picture is downloaded for the first time, it is stored on your device under the app’s cache. In case the app needs the picture again, it will just retrieve it from the cache instead of going to Twitter’s servers to download it.

Getting an image (and any kind of data) from the internal storage is massively faster than getting it from the internet, giving you a better experience when using the app. It also means that Twitter is consuming less of your precious data by doing so, and it puts less strain on Twitter’s servers. It’s a win for everyone, right?

If you have a phone with 32GB or more of internal storage, you will not care at all about apps’ caches filling up your device. However, if you have a device with low amount of on-board storage, then this can become a bit problematic over time.

Thus, Android provides an option to manually clear the cache of an app. Doing so will free up that precious space, letting you download new apps or take more pictures.
