Where to Start Troubleshooting iPhone Connecting and Disconnecting

The first thing to check is always the hardware which includes the ports, cables, and the iOS device itself. Doing this will save you a lot of time trying to fix a software issue on your PC or Mac that is actually caused by a faulty cable or phone.

1. Check the Cable

The usual culprit when a phone struggles with staying connected to a PC or Mac is the cable. Cables are small and lightweight – yet also are complex data transfer tools. A broken cable can still work sometimes, which causes intermittent failures that are harder to detect.

With iPhone cords, the connectors are also quite fragile, meaning that the connection issue can originate from either the phone’s charge jack or the computer’s connection port. Inspect the cable for any visually identifiable cracks or blemishes. Pay particular attention to the ends, making sure that there are no exposed wires due to the wear and tear of the connectors.

If there are no exposed wires, you can’t locate a crack in the cable, and the phone still won’t stay connected, try using a different cable. Even though you couldn’t find any visual evidence of a fault, there may still be one, so using another cable can help you localize the issue to a damaged communication wire.

2. USB Ports and iPhone Cable Jack

Although USB ports are generally very reliable, they can develop issues specifically relating to the connection ports. If the iPhone doesn’t stay connected or connects intermittently, try connecting a different device to the same port.

Similarly, if the iPhone’s cable jack is causing the problem, connect the phone to a charger to see if it also struggles to charge. This will show if a faulty jack is interrupting the cable from transferring power or data to the phone.

If you’re facing either of these examples, you’ll have to take the device in for repairs. Luckily, with a faulty USB, you can probably just use another port. However, if the problem originates from the iPhone’s cable jack, you’ll need to take it to an authorized service center.

3. iOS Device Settings

Apple devices are great for managing your content over all your different technology. Using iCloud and iTunes services, you have access to all your content from any of your Apple gadgets. Apple provides these services while also preventing the exploitation of copyrights and the privacy of the content owners.

This additional privacy protection can cause issues when connecting an iPhone to an untrusted computer. To fix the issue from the device’s settings, follow these quick steps:

  1. Go to Settings on the iPhone then choose General.

  1. If you now reconnect the phone to the computer, you should receive a prompt from iTunes allowing you to “Trust” the phone. Accept all the prompts and that should fix the connection issues.

4. Upgrade iTunes

In some cases, an outdated version of iTunes can also cause the iPhone connecting and disconnecting issue. To fix this, simply update your iTunes software.

To update, click on the Help menu and choose “Check for Updates”, then follow the prompts.

Are You Still Facing iPhone Connection and Disconnection Issue?

If none of the above has fixed your issue, you will need to investigate whether a device failure is happening.
