How do I completely delete apps on my iPhone

Tips
1

I’m running out of storage on my iPhone and I’m confused about the right way to fully delete apps and their data. Sometimes they seem to come back or still use space even after I remove them from the home screen. Can someone explain the proper steps to uninstall apps so they’re truly gone and free up storage?

Short version. Tapping an app icon and hitting “Remove from Home Screen” does not delete it. It only hides it. You need to delete from the App Library or Settings to free space.

Here is the clean way to wipe apps and their data on iPhone:

  1. Turn off “Offload Unused Apps” first

    1. Open Settings
    2. Tap App Store
    3. Turn off “Offload Unused Apps”
      If this stays on, iOS removes the app but keeps its data, so it feels like apps keep “coming back”.

  2. Fully delete apps from Settings
    This is the most reliable method.

    1. Settings
    2. General
    3. iPhone Storage
    4. Wait for it to load the list
    5. Tap an app
    6. Tap “Delete App”
    7. Confirm
      Do not tap “Offload App”, that keeps its data. Use “Delete App” so the app and its documents go away.

  3. Delete from the Home Screen correctly
    If you prefer doing it from icons:

    1. Long press the app icon
    2. Tap “Remove App”
    3. Pick “Delete App”, not “Remove from Home Screen”
      “Remove from Home Screen” hides it, the storage stays used.

  4. Delete from the App Library
    Sometimes the app is not on the Home Screen.

    1. Swipe left until you reach App Library
    2. Search for the app at the top
    3. Long press the app icon
    4. Tap “Delete App”
      That fully removes it, same as Settings.

  5. Clean up “Other” storage from old app data
    Some apps leave data in “System Data” or “Other”. You do not see this app by app.
    Steps that help:
    • Delete old Messages threads with lots of photos or videos
    Settings > Messages > Keep Messages > set to 1 Year or 30 Days
    • In Photos, delete big videos, then go to “Recently Deleted” and clear it
    • In Safari
    Settings > Safari > Clear History and Website Data

  6. Handle iCloud vs local confusion
    • If you delete an app, its local data goes, but iCloud data might still exist
    • For apps like WhatsApp, Telegram, etc, check inside the app settings for “Storage” or “Data and Storage” before deletion and clear from there
    • For iCloud Drive and app backups
    Settings > your name > iCloud > Manage Account Storage
    Remove old backups from devices you no longer use

  7. Reinstalling and “coming back”
    If an app seems to come back:
    • You likely had “Offload Unused Apps” turned on, so iOS kept its data and reinstalled it when you tapped the icon
    • Or it stayed in App Library and you thought it was gone because it left the Home Screen

  8. Big space wins you can check once
    • Photos and Videos
    Open Photos > Albums > scroll to “Videos” and delete the large ones you do not need
    • Messages
    Settings > General > iPhone Storage > Messages
    Check “Large Attachments”, delete big files from there
    • Streaming apps
    Netflix, Spotify etc often cache gigabytes
    Open the app, go into its settings and clear downloads or cache
    Or remove and reinstall the app from iPhone Storage menu

If you want to verify it worked, go to
Settings > General > iPhone Storage
Look at “Available” at the top before and after deleting. If that number goes up, the app and its data are really gone.

What @voyageurdubois wrote is solid, but there are a few extra gotchas that explain why stuff still seems to eat storage even when you’re “deleting” apps.

I’ll skip the basic delete steps and focus on the weird edge cases:

1. “Hidden apps” vs actually gone

Sometimes it feels like apps come back from the dead because of:

  • App Library & Search: Even after you remove an icon from the Home Screen, it still shows up in:
    • App Library (last page if you keep swiping right)
    • Spotlight search (swipe down on Home Screen and type the name)
      If it shows up and opens instantly, it’s still installed. If it shows a cloud icon or has to download, it was offloaded or reinstalled.

Quick test:

  • Search the app name.
  • If you see a little cloud with an arrow, the app itself was removed and only data or cloud metadata is around.

2. Apps that “keep” data in iCloud even after you delete them

Deleting the app from your iPhone does not automatically wipe what it stored in iCloud.

Check this specifically:

  1. Settings
  2. Tap your name at the top
  3. iCloud
  4. Manage Account Storage

Look here for:

  • Old app backups
  • Apps that still have data stored in iCloud

You can tap into each and turn off “Use iCloud” or delete that app’s data.
This doesn’t instantly give you local storage back, but it stops ghost data from reappearing when you reinstall.

3. The “it still uses storage” bug: caching & lag

Sometimes iPhone Storage lags and looks like the app is still there:

  • After you delete a few large apps, restart your phone.
  • Then go again to: Settings > General > iPhone Storage.
    iOS recalculates space and that “System Data” / “Other” blob can shrink.

Also, apps like Instagram, Facebook, TikTok, etc keep huge caches. Deleting and reinstalling them is often faster than digging through in-app settings.

4. The nuclear option when “System Data” is huge

If “System Data” or “Other” is several GB and nothing fixes it:

  • Back up to iCloud or computer
  • Settings > General > Transfer or Reset iPhone > Erase All Content and Settings
  • Set up as New iPhone first and check storage
  • Then if you want, restore only what you actually need, not every single app again

This is overkill but it’s the only guaranteed reset of all leftover junk from years of installs and deletes.

5. Watch out for these sneaky storage hogs related to apps

Even if you delete the main app, these can hang around or refill fast when you reinstall:

  • Messages: photos & videos you got from apps (IG links, TikTok links, etc)
  • Mail: big attachments sitting in the Mail app
  • Downloaded maps, playlists, videos: if you reinstall the app and re-download stuff, it fills right back up

Hit:
Settings > General > iPhone Storage > tap Messages, Mail, etc, and clear “Large Attachments” or big threads.

6. One thing I slightly disagree with @voyageurdubois on

They suggest always turning off “Offload Unused Apps.”
That’s true if you want predictable behavior, but if you’re really storage-starved and don’t mind apps vanishing occasionally, leaving it on can help you survive with a tiny-capacity phone.

Just know:

  • Offloaded app = app gone, data stays
  • Icon with small cloud = offloaded
    If that behavior annoys you, then yes, turn it off. If not, it can be useful.

Very quick sanity checklist

When you delete an app and want to be sure it’s really gone:

  1. Delete it from Settings > General > iPhone Storage using “Delete App”
  2. Restart your phone
  3. Check iPhone Storage again, see if free space actually went up
  4. Search the app name from Home Screen search
    • No result or only a cloud icon in App Store = you’re done

If after all that your phone is still full, the main culprits usually aren’t apps themselves but:

  • Photos / videos
  • Messages attachments
  • System Data bloated over time

Those need their own cleanup even if every app on the phone is perfectly “deleted.”

Quick angle they did not dig into: figuring out which apps are worth deleting before you start nuking things.

Instead of randomly deleting, do this once:

  1. Go to Settings > General > iPhone Storage.
  2. Ignore the individual app list at first. Look at the colored bar at the top. If “Apps” is not the biggest chunk and “Photos” or “System Data” is, you will not solve this just by deleting apps.

Now for apps specifically:

A. Sort out what is actually “heavy”

On the iPhone Storage list:

  • Tap the little sort hints: look for apps that are:
    • Small app size + huge “Documents & Data”
    • Example: 80 MB app, 3.5 GB data
  • Those are prime delete/reinstall candidates, because deleting them and reinstalling usually wipes caches that iOS will never show you clearly.

I slightly disagree with relying only on Settings > iPhone Storage > Delete App like @byteguru prefers. For some media apps (podcasts, music, cloud drives), going inside the app and clearing its downloads first gives you more control, so you do not accidentally kill stuff you still need offline.

B. Before deleting, check if the app is “replaceable”

Ask for each heavy app:

  • Does this app have a good web version?
    • Example: shopping, banking, airline check‑ins
    • Use Safari bookmarks instead of keeping a full app.
  • Is there overlap?
    • Two note apps, three photo editors, multiple scanners. Keep one, uninstall the rest.

This is where people save gigabytes without feeling like they have “lost” anything.

C. Watch for apps that secretly re‑download content

Even if @voyageurdubois is right about offloading behavior, another reason apps feel like they come back is that they re‑cache their content the moment you open them again.

Examples:

  • Podcast apps re-download recent episodes
  • Cloud storage apps re-cache previews
  • Social apps re-cache images and videos as you scroll

If your goal is long term free space, pick one or two “heavy network” apps to keep installed daily, and move others to web versions or only install them when needed, then delete again.

D. Silent storage hog: local backups inside apps

Some apps maintain internal “backup” folders you never see:

  • Note & journaling apps that keep multiple backup copies
  • File managers that keep ZIP exports
  • Camera apps that keep their own gallery separate from Photos

Before deleting these, open them and look for:

  • “Export / backup” sections
  • Secondary “trash” or “recently deleted” areas inside the app
    Empty those first so you do not lose something important when you eventually tap Delete App.

E. About the product title ’

Pros for ’ in this context:

  • Neutral placeholder if you later need a single term to refer to “your core storage cleanup routine” in notes or guides
  • Easy to search for if you build yourself a checklist in Notes like “’ step 1: check iPhone Storage”

Cons:

  • Completely non descriptive, so it is easy to forget what it referred to
  • Adds zero clarity when you are already confused about which deletion method does what

So if you are organizing tips for yourself, rename that concept to something meaningful like “My iPhone storage reset checklist” instead of '.

F. How I’d combine everything into a one time “storage reset”

Once a month (or when things get bad):

  1. Settings > General > iPhone Storage
  2. Identify:
    • Top 5 largest apps by “Documents & Data”
    • Whether “Photos” or “System Data” is the real villain
  3. For each top app:
    • Open the app
    • Clear downloads / caches / offline content from inside its settings
    • If still huge, delete the app entirely from iPhone Storage and later reinstall only if you really miss it
  4. Replace nonessential apps with:
    • Safari bookmarks for services that work fine on the web
  5. Restart the phone so storage numbers recalc.

Compared to @byteguru and @voyageurdubois:

  • I’d rely less on permanently turning off “Offload Unused Apps” and more on pruning apps so that the ones left are worth keeping fully installed.
  • I also put more weight on in‑app cleanup before deleting, so you do not lose important offline stuff by accident.

Once you run that cycle properly once, day‑to‑day deleting is way less confusing, and you will not feel like apps are haunting your storage every time you remove an icon.
