How to Fix iPhone Won't Sync on iOS 16 with 11 Useful Tips

Tip 4. Update your Firewall Settings

If the iPhone still won’t sync with iTunes, then chances are there that the system firewall is blocking iTunes operations. This firewall software program has the Security function, which prevents harmful operations. But sometimes, the Firewall also blocks iTunes from working correctly. This fix is typically for the Windows system, but you can also use it on Mac systems.

1. 1. Open the Control Panel and select the System & Security option. Pick the Windows Firewall option and review the list of apps that can communicate through firewalls.

2. 2. Make sure that the box in front of iTunes is checked, which means iTunes can operate without interruption of the Firewall software. Click on the “Ok” button to apply the changes, and now you can sync the device with iTunes.

   

Tip 5. Reauthorize iTunes

A major reason why the iPhone does not sync music to iTunes is a security concern that halts the sync session every time you try it. To fix this, you need to reauthorize your system with iTunes.

Step 1: Launch iTunes on your system and go to the Account tab. You will see the option that states “Authorizations.” Select the “Authorize This Computer” option and save changes.

When you have the authorization, the option won’t be highlighted. But when the option is highlighted, it means that you need to reauthorize your computer. Click on the option and wait for iTunes to finish the operation.

Tip 6. Restart your Computer

As a simple fix when the iPhone won’t sync to a computer, restarting it will be the easiest fix. It is essential that you restart your computer to implement the changes you recently made to the system.

Tip 7. Restart your iPhone

A simple restart is a soft fix for issues when the iPhone won't sync with the computer. If the problem is with the iOS device, not the system or iTunes, a simple restart is likely to resolve the issue. Fortunately, to restart the iPhone models, there is a common method.

For iPhone 8 or above:

Press and hold the Volume Up button > Press and hold the Volume Down button > Long press the Power button at the same time till the Apple logo appears.

For iPhone 7 or 7+:

Press and hold the Volume Down button and long press the Power button at the same time til the Apple logo comes.

For iPhone 6 or earlier:

Long press the Home button and the Power button at the same time till you see the Apple logo.

You can try syncing it after you have forced restart your iPhone.

Tip 8. Try Another Sync Method: Wi-Fi or USB

Just imagine that it is your Fitbit that won't sync with the iPhone, then switching the method of sync might be the answer to your problems. Fortunately, iTunes can sync with the connected device using USB cable and Wi-Fi. So, in case the USB is not working, you can turn on the Wi-Fi sync option.

Open iTunes and go to the Summary tab. In the Options tab, you will see the “Sync with this iPod over Wi-Fi” option.

Tick the option and try syncing the device. Hopefully, it will resolve the problem, and you will be able to sync your iDevice with iTunes seamlessly.

Tip 9. Update Driver

When the iPhone won't sync over Wi-Fi, this means that there is a problem with the drivers. Whenever you connect your device with a computer, it installs a driver that allows the devices to communicate with each other. So, when there is a problem in the connection that you can’t understand, then updating the drivers seem like an ideal solution.

1. 1. Open the Device Manager on your Windows system and select your device name.

2. 2. Right-click on the name and open Properties window. Switch to the Driver window, and you will see if there is an update required for the drivers installed.

   

Finally, click on the “OK” button to apply changes and make another attempt to sync your iPhone with iTunes.

Tip 10. Reset iPhone

When you can’t find an answer to “why won’t my Fitbit sync with my iPhone,” the least you can do is to try resetting your iPhone settings. The reset will erase the settings that might be interrupting with the optimal functioning of your device. To do this, follow the steps below:

1. 1. Launch the Settings app > General > Reset, and you will see the “Reset All Settings” option.

   
2. 2. Click on the option and enter your device passcode to confirm the reset. When the reset is finished, again try to sync your iPhone with iTunes or any other device.
