YouTube is one of the most frequently used apps on almost every user's phone. And the more often videos are viewed in it, the more memory the program starts to take up. There are several reasons why YouTube takes up smartphone memory:
Application cache. The largest item in size, which can reach several gigabytes. The YouTube cache stores various information that helps the application load faster: thumbnail images of videos or fragments that have been temporarily saved. This data in quick access allows YouTube to instantly display previews of videos in recommendations, as well as those videos that have already been viewed or stored in playlists (for example, playlists "Liked" or "Watch later").
Downloaded videos. If the user can download videos that can then be watched offline, the downloaded files are stored in the phone's memory. Their size depends on the quality of the video, as well as its duration.
Browsing history and search history. The more videos viewed and the more queries in the YouTube search bar, the more memory this item will take up.
Although the application can clog up enough memory on the phone, it can be cleaned without harm to the owner's personal data. All his preferences, recommendations and profile data will remain in the application, you can delete only those items that were described above.
There are several ways to clear YouTube's memory. At the same time, the minimum size of the application itself (about 100-200 MB) will still remain in the phone's memory.
