Most likely cause, if you text a ton and send pics and gifs it's taking up a bunch of unreported space. Deleting the messages will often free up double or triple the space it says.My phone and ipad do the same shyt...I don't have any music or movies on them, and they'll always get down to almost zero space left.
Best bet is to delete all your messages, esepcially if your gif game on point. I freed up 4GB on my ipad just deleting the messages, even though it said there was only 300 kb or some shyt
But also yeah, that 16 gb life been a wrap. esp if your photo and app heavy. Even when i had the 32 GB i ended up breaking down and paying that $1 for the icloud space. Freed up 16gb just from moving my pics to the cloud.
Now I'm living that 128gb life tho
