The problem that iPhone or iPad unable to check for update error sometimes happens in OTA update.

Here we provide 7 quick fixes for you to identify the reason or solve the problem. If you have already tried most of the common ways and think there may be a tricky system error, you can also go to Solution 7 directly to solve it with a third-party tool.

Solution 1. Make Sure Apple Servers Are Not Down

When your iPhone or iPad checks for update, it has to communicate with the Apple servers. If Apple servers are down, naturally your iPhone is unable to check for update or says iPhone update requested. So, there is possibility that the iOS 16 update failure is not caused by internal reason but some external elements. In order to check it, pay a visit to Apple System Status web page to see whether the servers are available.

If the icons show green, it means they are running normally. Then you can attribute the iPhone update failure to other reasons and try other alternatives to fix the issue. If there are yellow, red icons, or blue icons with annotations, you can wait for the servers getting back to normal and try to update once again later.

Solution 2. Ensure a Good Network Connection for Software Update

The "Unable to Check for Update" problem is usually due to a network issue. Since iOS OTA update requires a stable and smooth network condition, you need to make sure your iPhone/iPad has a good Wi-Fi signal strength.

If it seems that your Wi-Fi connection is weak while other devices can use it normally under the same connection, here are three ways to help you fix the network problem on your iPhone or iPad.

1.Reconnect Wi-Fi

2.Connect to Another Wi-Fi Network

If the reconnection doesn't work, you may need to try other working Wi-Fi networks. Head to Settings > Wi-Fi. Disconnect the current Wi-Fi network and connect to another effective one.

3.Reset Network Settings

If there is still an error in checking for software update on your iPhone or iPad, try to reset the network settings. Open Settings > General. Scroll down and tap Transfer or Reset iPhone. Tap on Reset Network Settings.
