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:
- Swipe all the way right to App Library.
- Use the search bar at the top and type the app name.
- 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:
- Open the app.
- Look for hidden tabs like Downloads, Offline, Files, Archive.
- 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:
- Make sure you have decent battery.
- Plug into power.
- 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.
