Sometimes you want to check iPhone storage from a full-size screen — maybe you are planning a cleanup, buying a new phone, or troubleshooting. Here is how to do it from Windows.

Quick Answer

Install the Apple Devices app from the Microsoft Store (or iTunes on older Windows), connect your iPhone via USB cable, tap Trust on your iPhone, then click the device icon in the app. The Summary or device overview screen shows your total storage, free space, and a color-coded bar by content type (Audio, Video, Photos, Apps, Documents, Other). You can also see this info in File Explorer under "This PC".

What You Need

  • A Windows 10 or Windows 11 PC
  • An Apple Lightning or USB-C cable (whichever matches your iPhone)
  • The Apple Devices app (Microsoft Store) on Windows 11, or iTunes on Windows 10
  • Your iPhone's passcode

Step-by-Step Instructions

1 Install Apple Devices or iTunes

On Windows 11, open the Microsoft Store and search for Apple Devices. Install it. On Windows 10, search for iTunes instead (Apple Devices is Windows 11 only). Either app works for checking storage.

2 Connect Your iPhone

Plug your iPhone into the PC using a Lightning or USB-C cable. Make sure the cable supports data transfer — some charging-only cables will not work. An Apple-made cable is safest.

3 Trust the Computer

Your iPhone will show a Trust This Computer? popup. Tap Trust and enter your iPhone passcode. This is a one-time step per computer.

4 Open Apple Devices (or iTunes)

Launch the app. Your iPhone should appear in the sidebar or top toolbar. If it does not, give it a few seconds, or disconnect and reconnect the cable.

5 View the Storage Breakdown

Click your iPhone's name. You will see a Summary or Overview page with a colored bar at the bottom showing storage usage by type — Audio, Video, Photos, Apps, Books, Documents & Data, and Other. Hover over each color segment to see the exact GB value.

6 (Optional) Check via File Explorer

You can also open File Explorer, click This PC, and your iPhone will appear as a portable device. Right-click and choose Properties to see total capacity and free space, though this view is less detailed than the Apple Devices app.

Troubleshooting

  • iPhone not detected: Try a different USB port, restart the Apple Mobile Device Service (services.msc), or reinstall Apple Devices.
  • No "Trust" popup: Unlock your iPhone, unplug and reconnect.
  • Storage bar shows nothing: Wait 30-60 seconds for the data to load after first connection.
  • Apple Devices crashes: Update to the latest version from Microsoft Store.
Tip: Once you see what is using space, the fastest way to clean up is directly on your iPhone. Swype Photo Cleaner lets you swipe through your library and free multiple gigabytes in minutes — no PC required.

Frequently Asked Questions

Can I check iPhone storage from a Windows PC?

Yes, using the Apple Devices app (Windows 11) or iTunes (Windows 10). Connect via USB, tap Trust, and view the summary screen.

Why does my PC not detect my iPhone?

Bad cable, missing Trust prompt, stopped Apple Mobile Device Service, or outdated drivers. Try a different cable and reinstall Apple Devices.

Does checking storage from a PC delete anything?

No. It is a read-only operation. Nothing is modified or deleted unless you explicitly perform an action.
