How Long Does the iOS 18 Take to Install in 2024

Part 1: How Long Does the iOS 18 Take to Install?

It’s difficult to quote a specific time frame for installing iOS 18 on your iPhone. It depends on various factors and may vary from device to device, including the internet and storage space available on your device.

Normally, iOS updates shouldn’t take more than 30 to 40 minutes, depending on the connection's speed. If you have a stable internet connection with good speed, it’ll take 5 to 15 minutes to download the updated file and 15 to 20 minutes to install it.

Updating your iPhone to the iOS 18 shouldn’t take you more than 30 to 40 minutes. However, users may face delays in the update process due to various reasons.

Part 2: Why Is My Update Taking So Long to Install iOS 18?

Updating your iPhone to the latest iOS 18 shouldn’t take you more than 40 minutes, and that’s when you have an average internet connection.

However, if you have a stable internet connection but are still facing the “iPhone taking forever to update iOS 18” problem, here are some potential reasons why.

1. Poor Internet Connection

Updating the iPhone to the iOS 18 includes downloading the updated files from Apple, which requires a stable internet connection with good speed. The updating process can be affected if the internet is down or does not offer enough speed to download the updated file.

If your device has any particular network issues due to an iOS bug or glitch, you can reset the network settings to configure them. Go to Settings >> General >> Transfer & Reset iPhone, and tap on the Reset Network Settings option.

2. Insufficient Storage Space

Another common reason for the slow installation or update process getting stuck midway is the need for more storage space. During the update process, the iOS firmware update files require free storage space. Low storage on an iPhone will prevent the server from receiving updated files, leading to a delay in installing the updated device.

The update can stop midway or take longer if there isn’t enough storage space on the device. This can be resolved by deleting unnecessary apps, photos, and long HQ videos. To see the breakdown of device storage, go to Settings >> General >> iPhone Storage.

3. Damaged Cable

If your iPhone’s iOS 18 update takes longer on iTunes, it can be an issue related to the damaged or faulty cable connecting the iPhone to the computer. Inspect the cable closely, and try again.

4. Apple’s Server is Down

When the new updates are released, millions of users try to install them as soon as possible. This causes Apple’s server to overload and may not respond efficiently until restored, leading to delays in the installation of software updates.

If you think this may be the reason why the iOS 18 installation on your iPhone is taking forever, consider updating it at different times when there’s less traffic on the server. For instance, try installing it in the early morning or late at night.

5. iOS Bug & Glitch

Sometimes, the delay in the iOS installation is due to an iOS bug or glitch interfering with the installation process. Restarting your iPhone is an efficient and easy way to get rid of temporary bugs and glitches in iOS.

If a simple restart doesn’t work, try deleting the previously downloaded iOS files from the device. For instance, if your iPhone is running iOS 17, delete the iOS 17 file by navigating to Settings >> iPhone Storage, scrolling down until you find iOS 17, tapping on it, and selecting Delete.
