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. 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. When the picture is downloaded for the first time, it is stored on your device under the app’s cache. 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. The app displays the profile picture of each account, consuming data in order to download it and show it to you. Let’s imagine this situation: you are scrolling down your Twitter feed. While it does work, it is important to know what it does and how safe it is to do it. One of the most common solutions to recoup those lost GBs is clearing the cache of your device.

Factor in the increasing amount of lack of microSD slots in recent phones, and the storage situation can easily become precarious. While a lot of OEMs are finally starting to equip their phones with decent amounts of storage, there’s still a lot of phones out there that just have not enough space for this day and age.
