The most common reason is not having enough free space on your device. Other causes can be a weak Wi-Fi connection, a broken update file, or a problem in the system. Often, the update file saved in iPhone Storage becomes unusable and needs to be deleted before you try again. Also, running apps in the background, using a VPN, or updating over mobile data can interrupt the update process. Now that you know the causes of this error, let’s discuss the solutions.
1. Restart and Charge Your iPhone
This may sound simple, but restarting your iPhone often fixes update errors, and it works for this iOS update issue as well. To restart your iPhone, press and hold the Power Button and the Home Button together until the ‘Slide to Power Off’ slider appears. Note: If your iPhone doesn’t have a Home button, press and hold the Side button and either the Volume Up or Volume Down button at the same time. Wait about 30-40 seconds before turning your iPhone back on. It’s also very important to make sure your iPhone is at least 50% charged before installing an update. Once you’ve charged your device, try installing the update again. IMPORTANT: The update will not install if your iPhone’s battery is below 50%.
2. Free Up Enough Space to Install the Update
You may also see this error if your device doesn’t have enough space for the new update. So, it’s a good idea to check your iPhone’s storage first.
3. Enable and Disable Airplane Mode
Turning Airplane Mode on and then off from your iPhone’s Settings disconnects and reconnects all wireless connections. Sometimes, this can help your device finish the update. Note: This is especially useful if the error is caused by a network problem when updating over Wi-Fi.
4. Turn Off Low Power Mode
If your iPhone is in Low Power Mode, updates may not install because certain features are limited to save battery.
5. Reset Network Settings
Resetting your network settings can help resolve errors that happen during an iOS update, especially if you only get this error while on your home Wi-Fi. Keep in mind, resetting your network settings will delete all saved Wi-Fi networks, Bluetooth connections, and network passwords from your iPhone. Note: You’ll need to reconnect to Wi-Fi and Bluetooth devices afterwards.
6. Turn Off VPN
If you have a VPN set up on your iPhone, it could prevent the update from connecting to Apple’s servers. You can temporarily turn off your VPN to install the update. If you are still unable to install the update, consider updating iOS through iTunes.
