How to Delete an iPhone Update (And What Happens When You Do)

When a new iOS update notification keeps appearing on your iPhone, it can feel relentless. Whether you're not ready to update, the update is causing storage headaches, or you simply want to remove a downloaded-but-not-installed update, there are clear steps to get it done. Here's what you need to know.

What "Deleting an iPhone Update" Actually Means

There's an important distinction to understand before diving in: you can delete a downloaded update that's sitting on your device waiting to be installed — but you cannot permanently block Apple's update notifications, and you cannot downgrade iOS by deleting an already-installed update.

When people search for how to delete an iPhone update, they usually mean one of two things:

  • Removing a downloaded iOS update that hasn't been installed yet (to free up storage or delay the update)
  • Dismissing or pausing update notifications so they stop appearing

These are different problems with different solutions.

How to Delete a Downloaded iOS Update

If iOS has automatically downloaded an update in the background, it may be consuming several gigabytes of storage on your device. Here's how to remove it:

  1. Open the Settings app
  2. Tap General
  3. Tap iPhone Storage
  4. Scroll through the list and look for the iOS update (it typically appears near the top)
  5. Tap on it
  6. Tap Delete Update
  7. Confirm when prompted

Once deleted, the update file is removed and that storage space is freed. Your iPhone will eventually re-download the update automatically unless you take steps to manage notifications.

What Happens After You Delete the Update

Deleting the update file does not turn off future download attempts. Apple's software update system will check for and re-download available updates when your iPhone is connected to Wi-Fi and charging. The download won't automatically install — installation still requires your manual confirmation — but the file may reappear in your storage.

Managing Update Notifications Without Deleting

If your goal is to stop the constant reminder rather than free up storage, there are a few approaches:

Temporarily dismiss the notification: You can tap "Remind Me Later" on the update prompt to delay it. This won't delete the downloaded file but will pause the badge and pop-up temporarily.

Turn off automatic downloads: Go to Settings → General → Software Update → Automatic Updates, then toggle off Download iOS Updates. This prevents iOS from downloading future updates in the background without your permission. It does not remove an already-downloaded file.

Install the update: Sometimes the simplest path is just updating. If storage or compatibility concerns are driving the hesitation, those are worth evaluating on their own terms.

The Storage Variable 📱

How much this matters depends heavily on your device's storage tier. On an iPhone with 64GB or less of storage, a downloaded iOS update taking up 3–6GB can meaningfully crowd out photos, apps, and cached data. On a device with 256GB or more, the same file may never register as a problem.

Storage TierImpact of Downloaded Update
64GB or underPotentially significant — may block app installs or camera use
128GBModerate — noticeable but usually manageable
256GB+Minimal — rarely causes day-to-day friction

This is worth considering when deciding whether deleting the update is actually necessary or just a cosmetic fix.

Why You Might Want to Keep the Update (Or Delete It) 🔍

Reasons to delete:

  • Your storage is low and you need the space now
  • You want to delay updating until a compatibility issue is resolved (e.g., an app you rely on hasn't been updated for the new iOS version)
  • You're waiting to see early user reports before updating

Reasons not to delete:

  • iOS updates frequently include security patches — delaying too long can leave your device exposed to known vulnerabilities
  • The file will likely re-download anyway, so it's a temporary fix
  • If you're on an older iPhone model approaching end-of-support, updates may eventually stop being available at all

What You Cannot Do

A few common misconceptions are worth clearing up directly:

  • You cannot roll back to a previous iOS version by deleting an update. Once iOS is installed, Apple stops signing older versions, making downgrades essentially impossible through normal means.
  • You cannot permanently block iOS updates from being offered — Apple's update system is built into the OS and will continue to notify you.
  • Deleting the update does not affect your current iOS version in any way. Your phone continues running exactly as it did before.

The Variables That Change the Answer

Whether deleting an iPhone update makes practical sense depends on factors that vary by user:

  • How low your storage actually is — check Settings → General → iPhone Storage for a full picture
  • Which iOS version is pending — a major version upgrade carries different risks and compatibility considerations than a minor security patch
  • Which apps you depend on — some apps take longer to update for new iOS versions, making delayed adoption reasonable
  • Your device's age — older iPhones may have more to gain from performance or battery-related improvements in updates, or more to risk if the update drops support for certain features

The mechanical steps for deletion are straightforward and the same across recent iPhone models. What differs — and what only you can assess — is whether deleting it now actually solves your real problem or just delays it.
