How to Fix “Unable to Check for Update” Error On iPhone
Here are all the tips you’ll learn about in this guide.
1. Ensure That Wi-Fi Is Enabled and That There Is a Strong Signal
One of the most common issues is not being able to connect to a Wi-Fi network or have a weak Wi-Fi signal.
To avoid being disconnected in the middle of an update download, you should start the process with a strong network connection.
First, make sure your phone’s Wi-Fi is turned on and that you’re connected to the network you want to connect to.
1. First, go to the Settings app.

2. Tap on Wi-Fi.

3. Ensure Wi-Fi is toggled on and you’re connected to the network.

2. Reset Network Settings
It’s possible that the issue stems from the Network settings. If this is the case, resetting the network may be able to resolve the problem.
1. Launch the Settings app.

2. Open General.

3. Scroll down to find the Transfer or Reset iPhone, then tap on it.

4. Now, select Reset.

5. Choose the Reset Network Settings option. You will have to enter the password of your device to confirm the action.

It is worth noting that all the settings will be erased without affecting the device’s data.
3. Check Apple Servers
Once you make sure that your connection is strong and your network setting is fine, then it’s time to check if Apple servers are working correctly.
Unfortunately, servers may go down from time to time, and in this case, you have to wait for a while and try again after some time.
You should visit the Apple System Status web page to check apple servers. If the server status is yellow, that means there are some issues with the server, and that’s why the update is not showing up.

If the status symbol is green, that means everything is fine.
4. Restart Your iPhone
If the servers are working fine and the Wi-Fi you are using is strong, then it’s still possible that your iPhone is experiencing a software glitch.
These kinds of issues can get fixed by restarting your iPhone. To restart your iPhone, follow the steps below:
1. Press and hold the Power and Volume Down buttons simultaneously.
2. Now, turn off your phone with the slider.
3. Wait a few moments and then turn on your phone.
Now check to see if the issue is fixed. If not, proceed to the next step.

2. Then, select General.

Wrap-Up: iPhone Unable to Check for Updates
We hope you found the tips in this guide useful in helping you get rid of the “Unable to Check for Updates” error on your iPhone.
If you’re installing the update, the progress bar might appear to be moving slowly. This is because the time an update takes depends on the update’s size, Wi-Fi signal strength, and internet speed.
Importantly, if your iPhone’s battery is low, make sure to connect your iPhone to a power source.
If your phone goes down in the middle of an update due to a low battery, connect to a power source, switch it on, and try again.
