iPhone IOS 16.1.1 The operation could not be completed input/output error

Hello gaspowersales,

Thanks for updating us with this information to provide additional clarity on what's occurring.

It sounds like the network connection may be interrupted after some time has passed, so let's see if we can isolate that as being related to the error you see. If you have Wi-Fi Assist enabled on your iPhone, see if disabling this will provide different results. Check out the information below for assistance with that, and you can find more details on this here: About Wi-Fi Assist - Apple Support

Turn Wi-Fi Assist on or off

Wi-Fi Assist is on by default. If you don't want your iOS device to stay connected to the Internet when you have a poor Wi-Fi connection, you can disable Wi-Fi Assist. Go to Settings > Cellular or Settings > Mobile Data. Then scroll down and tap the slider for Wi-Fi Assist.

We hope that's able to help, and feel free to contact Apple Support directly if you need to continue checking into this in more detail.

Have a great day!

Hi Gaspowersales,

We'd like to ensure that the software is not the root cause of the issue. With that being said, we suggest that you update to iOS 16.1.2. Please secure your data with a backup before proceeding: Update your iPhone or iPad

If you continue to experience the same behavior, we recommend that you reach out to Apple directly to help with the issue. You can follow this link to connect with them: Get Support

All the best.
