How do I completely uninstall apps on my iPhone

General
1

I’m running out of storage on my iPhone and noticed that deleting apps from the Home Screen doesn’t always seem to free up much space. Some apps also don’t show the usual delete option when I press and hold them. Can someone explain the correct way to fully uninstall apps and their data on an iPhone, and if there are any settings I should check to make sure they’re really removed

Yeah, iOS app deletion is a bit sneaky. If you want apps gone and storage freed, do this instead of only tapping the Home Screen.

  1. Check what uses space
    • Open Settings
    • Go to General > iPhone Storage
    • Wait for it to load, it might take a bit
    • You see a list of apps, sorted by size, including “App Size” and “Documents & Data”

  2. Fully delete an app
    From that iPhone Storage screen:
    • Tap the app
    • Tap “Delete App”
    • Confirm
    This removes the app and its data. That usually frees more space than deleting from the Home Screen.

  3. Offload vs delete
    On some apps you see:
    • “Offload App”
    Removes the app itself, keeps your data. Icon stays with a small cloud symbol. When you reinstall, your data comes back.
    • “Delete App”
    Removes app and all data. This is what you want if you need storage.

  4. For apps without a delete option on Home Screen
    If you long-press and see no “Remove App”:
    • Go to Settings > Screen Time > Content & Privacy Restrictions
    • Tap iTunes & App Store Purchases
    • Tap “Deleting Apps” and set to “Allow”
    Then try again from the Home Screen or use the General > iPhone Storage method.

  5. Delete from App Library
    If you use “Remove from Home Screen”, the app still lives in the App Library. To delete from there:
    • Swipe left until you reach App Library
    • Search or find the app
    • Long-press the icon
    • Tap “Delete App”

  6. Clear data from big apps before deleting
    Some apps store lots of junk:
    • Photos: Settings > General > iPhone Storage > Photos > “Review Downloaded Videos” or “Empty Recently Deleted”
    • Messages: In iPhone Storage, tap Messages and clear “Large Attachments”
    • WhatsApp: In the app, Settings > Storage and Data > Manage Storage, remove old media

  7. Remove system junk
    • Delete old offline music or videos in streaming apps
    • Delete downloaded Netflix / YouTube / Spotify content inside each app
    Those do not always clear fully when you remove only from the Home Screen.

  8. Restart after big cleanups
    After deleting a bunch of apps and data, hold Power + Volume Up, slide to power off, then turn the phone back on. Storage numbers update more accurately after a reboot.

If you still see “Other” or “System Data” huge in iPhone Storage, that usually drops after deleting apps, clearing Messages attachments, old Safari data, then restarting. Sometimes updating iOS helps too.

Two things iOS loves to do: hide storage usage and pretend apps are small when they’re actually hoarding junk. @viajantedoceu already covered the obvious “go to iPhone Storage and delete from there,” so I’ll skip repeating that and hit the parts iOS makes annoying on purpose.

1. Make sure you’re actually deleting, not just hiding

When you long‑press an app and choose “Remove from Home Screen”, that’s basically just shoving it in a closet. It’s still installed in the App Library and still eating space. If you see that option, don’t use it when you care about storage.

Instead:

  • Long‑press > make sure the option says “Delete App”
  • If you don’t see “Delete App” at all, jump to section 3.

2. Some apps keep data in iCloud or elsewhere

This is where people get tricked. You delete the app and… somehow the storage number barely moves.

Check for these:

a) iCloud backups full of app data

  • Go to Settings > [your name] > iCloud > iCloud Backup > [your iPhone]
  • Tap Manage Storage or similar
  • Look at what apps are included in the backup
  • Turn off backup for apps you don’t care about, then tap Delete Backup and create a fresh one

Deleting an app does not automatically wipe its backup data. That’s separate.

b) iCloud Drive / app cloud data
Some apps store stuff in iCloud Drive:

  • Settings > [your name] > iCloud > Manage Account Storage
  • Tap iCloud Drive or individual apps and delete leftover files

You can delete the app and still have gigabytes of junk sitting in iCloud, which then keeps syncing.

3. When an app literally won’t show “Delete”

If what @viajantedoceu suggested with Screen Time doesn’t fix it, check these extra things:

a) Deleting apps restrictions the other way
Sometimes people have a configuration profile from work/school:

  • Settings > General > VPN & Device Management
  • If there’s a profile, tap it and check if it “requires” certain apps
    • Managed apps often cannot be deleted at all
    • Only way around that is removing the profile (which might break work email / VPN etc.)

b) Home Screen layout locked by a profile
Same area:

  • Settings > General > VPN & Device Management
    Some org profiles lock app removal behavior. If you see that, it’s not a bug, it’s “on purpose.”

4. Apps that look small but are secretly huge

You’ll see stuff like:

App Size: 80 MB
Documents & Data: 4.5 GB

Killing the app helps, but sometimes they recreate cached junk from iCloud or from their own servers.

Before deleting:

  • Open the app’s own Settings and look for:
    • “Clear cache”
    • “Clear downloads”
    • “Remove offline content”
  • Streaming apps (Spotify, Netflix, YouTube, etc.) are notorious for this

Only after clearing their internal downloads, delete the app. That way you’re not just reinstalling and re‑filling it.

5. Messages, Photos, and “System Data” trap

This is where I slightly disagree with @viajantedoceu: restarting helps, but it’s not magic. The real work is:

Messages

  • Settings > General > iPhone Storage > Messages
  • Clean out:
    • Large Attachments
    • Videos
    • GIFs and Stickers

Photos

  • Open Photos > Albums > Recently Deleted
  • Empty that, or your deleted photos still count as storage

System Data / Other
You can’t directly delete it, but you can force it to shrink by:

  • Clearing Safari:
    • Settings > Safari > Clear History and Website Data
  • Deleting large apps and caches
  • Then updating iOS to the latest version and rebooting

It usually drops over time, not instantly.

6. Avoid auto‑reinstalling junk

A sneaky one: iOS can re‑download apps from iCloud automatically when you restore or set up a new device.

To avoid building the same mess again:

  • Settings > App Store
    • Turn off Automatic Downloads for Apps (if you want to stay in control)
  • When setting up a new iPhone, choose “Don’t transfer apps” and install only what you actually use

7. Nuclear option if storage is really busted

If your storage graph is totally whack (like “System Data” is 50+ GB and nothing helps):

  1. Back up only what you care about:
    • Photos to iCloud / Google Photos / computer
    • Important files manually
  2. Go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings
  3. Set up as New iPhone, not from backup
  4. Install apps manually instead of restoring the old app clutter

This is overkill but it’s the one method that guarantees no leftover app junk.

TL;DR without the fluff:

  • Don’t just “Remove from Home Screen”
  • Watch for iCloud backup and iCloud Drive data keeping app junk alive
  • Check for work/school profiles blocking deletion
  • Clear app caches inside the app before deleting
  • If System Data is massive and never shrinks, consider a clean setup instead of restoring the same bloated backup

iOS makes storage look simple, but under the hood it’s kinda a mess. Once you tackle iCloud stuff plus restrictions, deleting apps actually starts freeing real space instead of that sad “freed 50 MB” message.

Couple of extra angles that often get missed when you’re trying to really wipe apps and claw storage back:

1. Check “hidden” app installs via App Library searches

Sometimes you think an app is gone because it’s not on the Home Screen, but it’s still in the App Library and in use:

  1. Swipe all the way right to App Library.
  2. Use the search bar at the top and type the app name.
  3. If it appears, long‑press it there and delete.

This catches stuff you might have “removed from Home Screen” months ago and forgotten.

2. Offload vs Delete: stop iOS from half‑removing apps

I slightly disagree with the idea of always relying on iPhone Storage alone. iOS loves to offload apps instead of fully deleting them if you have Offload Unused Apps turned on.

  • Go to Settings > App Store
  • Turn Offload Unused Apps OFF

Reason:
Offloaded apps free app binaries but keep their data, so your storage graph is full of “Documents & Data” zombies. If you want a clean slate, you want full deletion, not half‑measures.

3. Use “Recently Deleted” for apps after a restore

If you recently restored from backup or updated iOS and apps sort of reappeared:

  • Open Settings > General > iPhone Storage
  • Scroll to the bottom and wait for it to finish calculating
  • Sometimes you’ll see apps marked with a little cloud icon when you search them on the Home Screen

If so, delete them again from iPhone Storage. This second pass is often what finally frees the space, especially after a restore from a cluttered backup.
@viajantedoceu already touched the Storage screen method, but not this “post‑restore double pass” trick, which can reclaim a surprising amount.

4. Apps tied to Apple features that are not obvious

Some apps are more integrated into the system than they look:

  • Mail, Notes, Reminders, Calendar
    Deleting the app is not the same as clearing its local data.

    • For Mail, go to Settings > Mail > Accounts and disable accounts or set them to fetch less / delete local copies.
    • For Notes, check Settings > Notes > Accounts and toggle off accounts you no longer use.

  • FaceTime & Messages
    Even if you rarely open them, their media piles up:

    • For Messages, after cleaning big attachments, go to Settings > Messages > Keep Messages and set to 1 Year or 30 Days so it doesn’t re‑bloat.

This is less about “app uninstall” and more “make sure the app cannot silently re‑grow after you cleaned it.”

5. Third‑party “downloaders” and document managers

Apps like file managers, document scanners, or video downloaders often cache files outside the obvious folder view.

Before deleting them:

  1. Open the app.
  2. Look for hidden tabs like Downloads, Offline, Files, Archive.
  3. Clear anything big from inside.

Then delete the app.
If you skip this, reinstalling later may just start the cycle again as it re‑downloads or syncs old stuff.

6. Photos linked to specific apps

Some apps save straight into the Camera Roll, others keep their own copy:

  • Open Photos > Albums
  • Scroll to Media Types and “From Apps” style sections (like WhatsApp, Instagram, etc., depending on iOS version)
  • Clean those app‑specific albums, then empty Recently Deleted.

This gives you space back that deleting the app itself will not touch.

7. Background downloads and auto media saving

If you keep some apps but want them not to refill storage:

  • For messaging apps (WhatsApp, Telegram, etc.):
    • Turn off auto‑save to Camera Roll.
    • Turn off auto‑download of media in their internal settings.

This prevents your phone from getting fat again immediately after your cleanup.

8. Profile / MDM twist that blocks partial removal

@viajantedoceu already hit on the fact that work or school profiles can block deleting apps. One extra detail:
Some profiles do not fully block deletion, they only block removal of specific “required” apps while allowing others.

  • Go to Settings > General > VPN & Device Management
  • If there is a management profile, tap it and read the App Management or similar section.

If a crucial unwanted app is marked as “required,” you are stuck with it unless you remove the entire profile, which might kill things like corporate mail or Wi‑Fi access.
In that case, you cannot truly “completely uninstall” those apps without giving up the profile.

9. When “System Data” is eating what app removal should free

If you delete a ton of apps and the free space barely goes up, sometimes the space jumps into System Data temporarily. To push iOS to recalc:

  1. Make sure you have decent battery.
  2. Plug into power.
  3. Leave the phone locked and on Wi‑Fi for a while.

I’ve seen the System Data bar shrink overnight after big deletions without needing the full nuclear wipe. The complete reset that was mentioned is still the most reliable fix for truly wrecked storage, but it’s not always mandatory.

10. Quick pros & cons style view on this whole cleanup approach

Pros:

  • You end up actually freeing GBs, not MBs.
  • Avoids surprise re‑installs and silent re‑growth of data.
  • Lets you keep the phone usable without immediately jumping to a full erase.

Cons:

  • Several settings are scattered and not obvious.
  • Managed devices from work / school can hard‑block you.
  • Takes time and a couple of passes for iOS to show the real storage gain.

If you follow what @viajantedoceu outlined for iPhone Storage plus this extra stuff (offload toggle, App Library search, app‑linked media, background downloads, and the System Data recalculation), you get as close as iOS allows to a true “complete uninstall” without wiping the whole phone.
