    How to See What's Using Your iPhone Storage — and Fix It

    Go to Settings > General > iPhone Storage to see exactly what's taking up space, then delete large apps or offload unused ones to free storage fast.

    1

    Open the iPhone Storage screen

    ~18s
    Open the Settings app (the gray icon with gears). Tap "General," then tap "iPhone Storage." Wait 10–20 seconds for the screen to load — it needs to calculate storage for every app. You'll see a colored bar at the top and a list of apps below it, sorted from largest to smallest.
    2

    Look at the breakdown bar and recommendations

    ~20s
    The bar at the top shows how your total storage is divided by color: yellow for Photos, blue for Apps, purple for Media, and gray for other. Below the bar, iOS often shows "Recommendations" for freeing space — for example, "Auto Offload Unused Apps" or "Review Large Messages." Tap any recommendation to act on it immediately.
    3

    Delete or offload large apps

    ~32s
    Scroll through the app list and look for large items — especially games, video streaming apps with downloaded content, and photo/video editing apps. Tap an app to see options. "Offload App" removes the app file but keeps your data and settings (recommended for apps you might want again). "Delete App" removes both the app and its data completely.

    Quick Tip

    Games are often the safest to delete if you don't play them — they can be re-downloaded for free from the App Store. Your game progress may or may not be saved depending on whether the game uses cloud saves.

    4

    Clear large message conversations

    ~29s
    On the iPhone Storage screen, scroll down to find "Messages" in the app list. Tap it to see a breakdown of message storage by category: "Top Conversations," "Photos," "Videos," and "GIFs & Stickers." Tap "Review Large Attachments" to see the largest individual items. Swipe left on any item to delete it, or tap "Edit" to select and delete multiple items at once.

    Quick Tip

    You can also delete an entire message thread. In the Messages app, swipe left on a conversation and tap "Delete" to remove it along with all its attachments.

    5

    Turn on Offload Unused Apps

    ~31s
    Back on the iPhone Storage main screen, look for the "Offload Unused Apps" recommendation and tap "Enable" if it appears. This setting tells iOS to automatically remove apps you haven't used in a while when you're low on storage. The apps come back when you tap them. You can also enable this in Settings > App Store > scroll down to "Offload Unused Apps."

    Warning

    Some apps lose your local data if offloaded, even though the icon stays. Confirm any important data is backed up to the cloud (like your contacts, photos, and passwords) before relying on this feature.

    6

    Check and manage your Photos storage

    ~32s
    If Photos is using the most storage, open Settings > Photos and look for "Optimize iPhone Storage." Turn this on — it keeps smaller, compressed versions of your photos on your iPhone and stores the full-resolution originals in iCloud. You'll need iCloud storage space for this to work, but your 5 GB of free iCloud space is often enough for hundreds of photos.

    Quick Tip

    To see exactly how much of your iCloud storage you're using, go to Settings > tap your name at the top > iCloud. The bar shows how much of your storage is used and by what.

    When your iPhone shows "Storage Almost Full" warnings or says it can't take a new photo, it's time to look at what's using your storage. The good news is that iPhone has a built-in storage management screen that shows you exactly what's taking up space, sorted by size — so you know immediately where to focus.

    The storage breakdown is in Settings > General > iPhone Storage. Give it a moment to load, and you'll see a colored bar at the top showing how your total storage is divided (apps, photos, media, etc.), followed by a list of every installed app sorted from largest to smallest. You can tap any app to see how much space the app itself takes versus the data it's storing.

    A few categories almost always account for the most space: Photos and Videos (often the biggest), Apps (especially games and apps with downloaded content), and Messages (especially if you send and receive lots of photos and videos in text threads).

    iPhone offers a feature called "Offload App" that's different from deleting an app. Offloading removes the app itself (freeing up its storage) but keeps your documents and settings. The app's icon stays on your home screen with a small cloud download symbol. When you tap it later, the app re-downloads quickly and picks up right where you left off. This is useful for apps you want to keep but don't use often.

    iOS can be set to automatically offload apps you haven't used in a while, which is a good way to keep storage from creeping up.

    Clearing large message threads is another big opportunity most people overlook. A text conversation full of shared photos and videos can easily be using 1–2 GB of storage.

    This guide works on any iPhone running iOS 13 or later — which covers virtually all iPhones currently in use.
