iPhone Keeps Connecting and Disconnecting

If your iPhone keeps connecting and disconnecting from your computer or charger, it can be a frustrating experience. This issue can be caused by various factors, including software glitches or hardware problems. In this article, we will walk you through some troubleshooting steps to help you resolve the issue. We will also discuss two permanent solutions: resetting the System Management Controller (SMC) and resetting the Non-Volatile Random-Access Memory (NVRAM) on your iPhone.

Troubleshooting Steps

Before proceeding with the permanent solutions, it’s important to go through some basic troubleshooting steps. Follow these steps to troubleshoot the issue:

  1. Check the cable and adapter: Ensure that you are using a genuine Apple cable and adapter. Faulty or third-party accessories may cause connectivity problems.

  2. Try a different USB port: Connect your iPhone to a different USB port on your computer. Sometimes, a faulty USB port can cause connection issues.

  3. Restart your iPhone and computer: Restart both your iPhone and computer to refresh their systems. This can resolve temporary software glitches that may be causing the problem.

  4. Update your iPhone and computer: Make sure your iPhone and computer are running the latest software updates. Outdated software can sometimes cause compatibility issues.

  5. Reset network settings on your iPhone: Go to “Settings” > “General” > “Reset” > “Reset Network Settings” on your iPhone. This will reset all network-related settings, including Wi-Fi, Bluetooth, and VPN configurations. Note that you will need to reconnect to Wi-Fi networks and reconfigure other network settings after performing this reset.

  6. Disable USB selective suspend (Windows): If you are using a Windows computer, follow these steps to disable USB selective suspend:

    • Press Windows + X and select Device Manager from the menu.
    • Expand the Universal Serial Bus controllers section.
    • Right-click on each USB Root Hub and select Properties.
    • Go to the Power Management tab and uncheck the option that says “Allow the computer to turn off this device to save power”.
    • Repeat this for all USB Root Hubs listed.
  7. Try a different computer or charger: Connect your iPhone to a different computer or charger to see if the issue persists. This can help identify if the problem is specific to your current setup.

If the issue still persists after trying the troubleshooting steps mentioned above, you can proceed with the following permanent solutions.
