iPhone Music app “Documents & Data” is too big after turning on “Sync Library”

I have an iPhone 6s using iOS 15.5 and I turned on “Sync Library”, so I can access all my MacBook mp3 library from my phone. Can’t remember exactly when it started, but “Documents & Data” storage of iPhone Music app is too big (currently 8.15 GB). If I turn off “Sync Library”, then “Documents & Data” storage decrease to around 2.50 GB.

I’m not sure if the increase in size after turning on sync library is a common issue for iPhone users or is it because the greater the mp3 library in a MacBook (mine has 440 GB), then much more storage for “Documents & Data”. Anyone with similar situation?

Hey there luciomagano,

The documents and data you see is typically from album art and other items associated with your music. When you enable this feature, it's expected to see an increase in storage, especially since it's syncing from your Mac as well.
