How to Safely Clear Apple Music Cache on iPhone

If you use Apple Music every day, you may be surprised that the Music app is eating gigabytes of your iPhone storage — even if you only stream and never tap "download." Audio files quietly accumulate in the background, and there's no obvious button to wipe them.

How do I clear the Apple Music cache on iPhone? There's no single "Clear Cache" button, but you can safely reclaim the space in four steps:

  1. Delete downloaded songs — Settings > Music > Downloaded Music, then remove large artists or playlists.
  2. Turn off Automatic Downloads — stop iOS from saving every song you add to your library.
  3. Turn on Optimize Storage — let iOS auto-remove music you haven't played in a while.
  4. Delete and reinstall the app — the only native way to purge the invisible streaming cache.

None of this deletes your library or playlists — those are tied to your Apple Account in the cloud. Here's why Apple Music hoards storage and how to clean it without losing anything.

Why Apple Music Uses So Much Space

The Music app consumes storage in two completely different ways: Downloaded Music and the Streaming Cache.

1. Downloaded Music (intentional offline files)

When Automatic Downloads is on, every song you add to your library is saved to local storage for offline listening. In high quality this adds up fast — Apple's Lossless format can run roughly 10–50MB for a single track depending on the song and tier, and Hi-Res Lossless is larger still. A big library can easily occupy several gigabytes.

2. The Streaming Cache (the hidden hog)

When you stream a song, Apple Music keeps a temporary cached copy so it can replay instantly without re-downloading. Stream for hours a day and this cache balloons, showing up as "Documents & Data" or rolling into System Data without any visible list you can prune.

Remove Downloaded Songs and Fix the Settings

To recover space immediately, delete the music saved locally on your device.

  1. Go to Settings > Music > Downloaded Music.
  2. iOS lists every artist saved on your phone, sorted by size.
  3. Swipe left on an artist (or tap Edit) to remove their downloads.

Why this is safe: deleting a download does not remove the song from your Apple Music library — it just frees the local file, so you'll stream it next time. Your playlists are untouched.

Stop it from coming back: still in Settings > Music, scroll to Downloads and turn Automatic Downloads to OFF.

Turn On 'Optimize Storage' for Music

If you like keeping music for flights or the subway but don't want to babysit storage, let iOS manage it.

  1. Go to Settings > Music.
  2. Tap Optimize Storage and toggle it ON.
  3. Pick a Minimum Storage threshold (for example 8GB, 16GB, or 32GB).

When your iPhone runs low, iOS automatically removes the local files of songs you haven't played in a while, keeping Music's footprint under the limit you chose. Anything removed can be re-downloaded with a tap.

How to Force-Clear the Streaming Cache

If you've deleted all downloads but Music still shows up as a large item in Settings > General > iPhone Storage, you're looking at a bloated streaming cache.

Because there's no in-app "Clear Cache" control, the reliable way to purge it is to reinstall the app.

  1. On the Home Screen, long-press the Music app icon.
  2. Tap Remove App, then Delete App.
  3. Open the App Store, search Apple Music, and reinstall it.

Why this is safe: your library, playlists, and downloads-on-demand all live with your Apple Account in iCloud. The moment you sign back in, everything reappears — only the temporary cache is gone.

What actually counts toward Music's storage?

Storage type What it is How to clear it Reversible?
Downloaded Music Songs saved for offline play Settings > Music > Downloaded Music Yes — re-download anytime
Streaming cache Temp files from streaming Delete & reinstall the app Yes — rebuilds as you listen
Library & playlists Your saved music list Lives in iCloud, don't delete N/A

FAQ

Does clearing the Apple Music cache delete my playlists? No. Playlists and your library are stored with your Apple Account in iCloud. Clearing the cache or reinstalling the app only removes local temporary files; your music list reappears when you sign in.

Why is Apple Music using gigabytes if I only stream? Streaming builds a hidden cache so songs replay without buffering, and Automatic Downloads may be silently saving every track you add. Turn off Automatic Downloads and reinstall the app to clear both.

Is it safe to delete the Music app to clear its cache? Yes. Deleting and reinstalling Music purges the cache but keeps your cloud library intact. You'll just need to re-download any songs you want available offline.

Still seeing the 'Storage Full' warning? If Apple Music is tidy but your iPhone is still full, the real bloat is usually in your camera roll. Instead of deleting bad selfies one by one, Cleanor scans your photos in seconds, isolates large 4K videos, and groups blurry, near-duplicate burst shots so you can clear them in a tap. Anything you remove sits in Recently Deleted for about 30 days, so the cleanup is always reversible. Learn more on the Cleanor for iPhone page.
