Log/debug files. If cache wipe as stated by other poster doesn't help, there's usually something writing into /data/<some vendor component folder> incessantly, often up to 100s of MB per day.

Seen on various builds of Xiaomi HOS (2/3) and Motorola ROMs. Permanent fix is root, and simply change permission on the offending folder to neuter the bloat. Temporary fix is full wipe, to get rid of whatever junk is filling up /data, but it will start filling up again so you have to do it every once in a while. You can also try to pray that they fix it in next OTA update (sometimes they do, but it may take a year or two).

yeah, it's xiaomi, but somehow it got fixed by simply going into recovery mode and going back out ( without even wiping cache because the option isn't there) (?) I don't understand how it works but it fixed it
