Part 1. Why Is the iPhone Stuck on Update Completed?

Here are some of the common reasons behind the iPhone being stuck on update completed issue:

• Weak network: Updating iPhone requires a fast and strong internet connection. If the internet connection is not stable and fast enough, it may lead to this issue.
• Insufficient storage: Another thing that can cause the stuck issue is the lack of storage in your iPhone.
• Overheating: Sometimes, overheating can also cause the stuck issue. Make sure that your iPhone is away from sunlight during the update. Also, remove the back cover of the device to keep it cool.
• Corrupted data: Sometimes, corrupted data on third-party or system applications can cause this problem.

Part 2. Fix iPhone Stuck on Update Completed Screen

Here are the fixes you can consider trying to get rid of the iPhone stuck on the update completed screen:

Just Wait for a Moment

We recommend waiting for a bit more. In most cases, the problem occurs because of a slow internet connection. Moreover, the time can also be prolonged because of so many files on your device. In these cases, you should do nothing but wait.

Plug iPhone into a Charger

If you found your device on the stuck screen while updating, consider plugging it into the charger. As per some users, this method helped them get rid of the issue. Apple typically recommends keeping the charger connected while updating.

However, we will not recommend this as it can produce a lot of heat and damage the battery. Instead, charge the battery to 100% before starting the update. And connect the charger if the iPhone runs into the stuck screen.

Check Wi-Fi Connection

A stable and fast Wi-Fi connection is imperative while updating your iPhone. If the connection is slow or weak, you can end up in the stuck issue.

• You can refresh the network by restarting the router.
• Another thing you can consider is switching to a different Wi-Fi network which is faster.

Restart Your iPhone

If waiting, connecting to the charger, and changing Wi-Fi doesn't work, consider restarting the iPhone. Here is how to do this:

• For the iPhone with Face ID: Press and hold one of the volume buttons and the side button together. Once the slider occurs, let the button go and drag the slider to turn off the device. After a few seconds, press and hold the side button until the Apple logo occurs to turn on the device.
• For the iPhone without a Face ID: Press and hold the Power button. Once the slider occurs, let the button go and drag the slider to turn off the device. After a while, press and hold the Power button until the Apple logo occurs to turn on the device.

Clear Up Local Space

Another reason that can lead to the stuck is the lack of local storage on the device. In this case, you will need to clean up the device and delete unnecessary files to make space for the update. Remove the unwanted apps, photos, videos, app cache, app data, etc., to release some spaces.

Check the Hardware Issue

If the problem persists, your device might have a hardware issue. You can go to the nearby Apple outlets to get a professional check. They will inspect the device and let you know about the error in detail.
