App developers on Android rarely bother to clean their app caches. Open Apps in settings, sort by size, check top entries and you'll be surprised. Explain to me why the hell does Instagram need 500 MB of cache.
Kind of a bummer I don't know of any method to mass clear cache data of all apps on my non-rooted Galaxy S8. It'd save a lot of space and was possible on ancient HTC phones with Android 2.3.5.
Edit: I experimented with wiping cache partition in recovery mode, but this ain't it - as the name suggests it's a separate partition.
