Trying to update your iPhone but the update refuses to install? An iPhone update may fail because of insufficient storage, a weak internet connection, low battery, Apple server problems, outdated software, or an interrupted download.
If your iPhone is stuck on “Unable to Check for Update,” “Unable to Install Update,” “Update Requested,” or the update simply does not appear, there are several troubleshooting steps you can try before contacting Apple Support.
This guide explains how to fix iPhone update not working using simple solutions, starting with the safest and easiest methods.
Quick Overview: Why Is My iPhone Update Not Working?
Before trying advanced troubleshooting, check these common causes:
- Your iPhone does not have enough available storage.
- The Wi-Fi connection is unstable.
- Your iPhone battery is too low.
- The iPhone cannot communicate properly with Apple’s update servers.
- The downloaded update file is corrupted.
- Your current iOS version has a temporary software problem.
- The iPhone is managed by a company or school.
- Apple’s servers are experiencing unusually high traffic.
- The iPhone model may not support the latest iOS version.
In many cases, restarting the iPhone and checking storage or Wi-Fi can resolve the problem quickly. iPhone Update Not Working can stop your device from receiving new features.
1. Check Your Internet Connection
A reliable internet connection is one of the most important requirements for downloading an iOS update.
If your iPhone is connected to weak or unstable Wi-Fi, the update may remain stuck at “Update Requested” or fail during the download.
Try these steps:
- Open Settings.
- Tap Wi-Fi.
- Check that you are connected to a reliable network.
- Move closer to your Wi-Fi router if the signal is weak.
- Try disconnecting and reconnecting to Wi-Fi.
- If possible, test another Wi-Fi network.
Avoid relying on an unstable connection while downloading a large iOS update.
Quick tip
If websites and apps are also loading slowly, the problem may be your internet connection rather than the iPhone update itself. Fixing iPhone Update Not Working problems helps improve system performance.
2. Restart Your iPhone
A simple restart can clear temporary system glitches that interfere with software updates.
If your iPhone is behaving strangely or the Software Update screen is not responding, restart the device before trying another solution.
Restart an iPhone with Face ID
- Press and hold the side button and either volume button.
- Drag the power-off slider.
- Wait approximately 30 seconds.
- Press and hold the side button until the Apple logo appears.
After the iPhone restarts, connect it to Wi-Fi and try checking for the update again. iPhone Update Not Working may occur because of network connection issues.
Restart an iPhone with a Home button
Press and hold the side or top button until the power-off slider appears. Turn off the iPhone, wait a moment, and then turn it back on. Many users face iPhone Update Not Working during software installation.
3. Make Sure Your iPhone Has Enough Storage
Insufficient storage is one of the most common reasons an iOS update cannot be installed.
Even if the update itself appears to require a certain amount of space, your iPhone may need additional temporary storage while preparing and installing the software.
Check available storage
- Open Settings.
- Tap General.
- Select iPhone Storage.
- Review the available space.
You can remove unnecessary apps, videos, photos, downloads, and other large files if storage is almost full. iPhone Update Not Working can happen when storage space is insufficient.
What should you delete first?
Large video files are often a good place to start. You can also review unused applications and downloaded media. Restarting the device may solve some iPhone Update Not Working errors.
If you use iCloud Photos, make sure you understand how your photos are being stored before deleting anything.
4. Connect Your iPhone to a Charger
Some iOS updates may not proceed when the device has insufficient battery power.
Connect your iPhone to a reliable charger and leave it connected while checking for and installing the update.
For best results:
- Use a reliable charging cable.
- Connect directly to a power source.
- Keep the iPhone connected during the installation process.
- Avoid repeatedly disconnecting the device during an update.
If your battery is very low, charge the iPhone before attempting the update again. iPhone Update Not Working issues can delay important security updates.
5. Check Apple’s System Status
Sometimes the problem is not your iPhone.
When a major iOS update becomes available, many users may attempt to download it simultaneously. High demand or a temporary Apple service problem can interfere with the update process.
If everything looks normal on your iPhone but the update still fails, check Apple’s system status page for service interruptions.
If Apple’s services are experiencing problems, waiting until the service is restored may be necessary. Checking Apple settings may help resolve iPhone Update Not Working problems.
6. Delete the Downloaded iOS Update and Try Again
If an update downloaded incorrectly or became corrupted, deleting the downloaded update can sometimes solve the problem. iPhone Update Not Working can be caused by temporary software bugs.
How to delete an iOS update
- Open Settings.
- Tap General.
- Select iPhone Storage.
- Look for the downloaded iOS update in the list.
- Tap the update.
- Select Delete Update.
- Confirm the deletion.
Afterward, restart your iPhone, reconnect to Wi-Fi, and return to:
Settings → General → Software Update
Then download the update again.
Important
Only delete the downloaded update file. Do not delete personal photos, contacts, or other important files unless you have confirmed they are safely backed up.

7. Turn Off VPN Temporarily
A VPN or network-filtering application can sometimes interfere with connections required by Apple’s software update process.
If you are using a VPN, temporarily disconnect it and try updating again.
You can also check:
Settings → General → VPN & Device Management
The exact menu options may vary depending on your iOS version and configuration.
If your iPhone belongs to a company or school, do not remove a management profile without permission from the administrator. iPhone Update Not Working may prevent users from installing the latest iOS version.
8. Reset Network Settings
If your Wi-Fi connection appears normal but the iPhone still cannot download an update, resetting network settings may help.
Go to:
Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings
Keep in mind that this removes saved Wi-Fi networks and passwords, along with other network-related settings. A weak internet connection can cause iPhone Update Not Working issues.
Before resetting
Make sure you know your important Wi-Fi passwords because you will need to reconnect to your networks afterward.
This method is particularly useful if your iPhone has recently experienced Wi-Fi, cellular, VPN, or network connection problems. iPhone Update Not Working sometimes appears after failed download attempts.

The button combination depends on the iPhone model.
iPhone 8 and newer
- Quickly press and release the Volume Up button.
- Quickly press and release the Volume Down button.
- Press and hold the Side button.
- Release the button when the Apple logo appears.

Find your iPhone model
Go to:
Settings → General → About
Look for the model information.
Then compare your model with Apple’s official compatibility information for the iOS version you want to install.
This is especially important when using an older iPhone. Users should check system status when iPhone Update Not Working happens.
12. Make Sure You Have a Backup
