Fix iOS 18.4.1 Not Downloading on iPhone and iPad
The failed software update issue can occur due to a variety of reasons like poor internet connectivity, low storage space, or temporary glitches in the system. In this guide, I’m going to walk you through 10 effective solutions to resolve the issue. Each method includes a valid reason why it works, so you’ll know exactly what’s causing the problem and how to fix it.
1. Check Internet Connection
It’s important to point out that a stable Wi-Fi connection is required to download iOS updates. So, make sure your internet connection is up to the mark.
- On your iPhone or iPad, head over to the Settings app > Wi-Fi, make sure you’re connected to a reliable network, and try switching to another Wi-Fi if the current one is unstable.
- Avoid using mobile data as large updates like iOS 18.4.1 are typically restricted to Wi-Fi.

2. Restart Your iPhone or iPad
Note that temporary system glitches on iOS/iPadOS can interfere with the update process. But bother not! A simple restart can refresh the system and clear minor bugs that might be causing the download to stall.
3. Free Up Storage Space
It’s no secret that iOS updates require enough free space to be downloaded and installed.
- Go to the Settings app on your iPhone and iPad > General > iPhone Storage and delete unnecessary files, apps, or photos to make room for the update.

4. Check Apple’s System Status
Sometimes, the issue is on Apple’s end, not yours.
- Visit Apple’s System Status page and make sure the “iOS Software Update” service is running normally.
5. Disable Low Power Mode
It’s worth mentioning that the Low Power Mode restricts background processes to save battery, which can interfere with downloads.
- To get rid of the power-saving mode, navigate to the Settings > Battery and turn off Low Power Mode before trying to update.

6. Ensure Your Device Is Compatible
Older devices may no longer support the latest iOS version. So, visit Apple’s official site to check if your iPhone or iPad model supports iOS 18.4.1.
7. Reset Network Settings
Keep in mind that the corrupt network settings can block the connection required for downloading updates.
- Fire up the Settings app on your iPhone and iPad > General > Transfer or Reset iPhone > Reset > Reset Network Settings.
- It will erase saved Wi-Fi passwords.

8. Delete the Previous Update File
If a previous attempt to download the update failed, the corrupt file may block new downloads.
- Launch the Settings app on your iPhone or iPad > General > iPhone/iPad Storage.
- Now, locate the iOS update under the list of apps, and delete it. Then try downloading again.
9. Update via Finder or iTunes
No luck as yet? If the OTA (Over-The-Air) update fails, try updating manually through a computer.
- To get going, you need to first connect your device to a Mac (using Finder) or a Windows PC (using iTunes), and select Check for Update to install iOS 18.4.1.
10. Wait and Try Again Later
Apple’s servers may be overwhelmed, especially just after a new iOS release. If none of the above methods work, wait a few hours and try again during off-peak times for better results.
Wrapping Up
Updating to iOS 18.4.1 should be a straightforward process, but if it’s stuck or not downloading, these troubleshooting steps can help you fix the problem quickly. From checking your Wi-Fi connection and clearing storage to resetting settings or using a computer, each solution addresses a specific cause behind the issue. Try them one by one, and your device should be running the latest iOS version in no time.
