Apple Maps can use storage on iPhone from downloaded offline maps and a cache of tiles and search data. To reclaim it, delete offline maps in Maps > your profile > Offline Maps, and clear the broader cache by offloading the app if needed. Removing offline maps only means you re-download an area when you next need it offline — your favorites and history stay.

TL;DR

  • Two sources: downloaded offline maps (large, deliberate) and cached tiles/search (smaller).
  • Delete offline maps: Maps > profile picture > Offline Maps > (swipe a map) > Delete.
  • Clear the rest by offloading Maps in Settings > General > iPhone Storage > Maps > Offload App.
  • Offline maps re-download on demand; favorites and guides are kept.
  • A downloaded city/region can be hundreds of MB to a few GB.

Why does Apple Maps use storage?

Since iOS 17, Apple Maps lets you download regions for offline use — those packs are the big consumer, often hundreds of megabytes each. On top of that, Maps caches map tiles, search results, and recent routes as you browse. The offline packs are intentional; the cache rebuilds itself.

How to delete offline maps

  1. Open Maps.
  2. Tap your profile picture (top right).
  3. Tap Offline Maps.
  4. Swipe a downloaded map left and tap Delete, or tap a map to see its size first.

How to clear the Maps cache

iOS gives Maps no in-app "clear cache" button, so clear it by offloading:

  1. Settings > General > iPhone Storage > Maps.
  2. Tap Offload App, then reinstall. Offloading clears the cached footprint while keeping your favorites, guides, and settings.

What iOS does natively, and where it stops

Offline Maps management is built in and clear. The limit: there is no cache button for Maps, so the cache only clears via offload, and Maps will not surface its size next to the bigger media on your phone. Maps is rarely the largest item.

What this cannot do

Deleting offline maps means you need a connection (and to re-download) to use that area offline again. Offloading keeps your data, but a full Delete App would remove favorites that are not synced to iCloud — so offload, do not delete, unless you are fine re-setting it up.
