If your Realme 16 is not recognizing a USB-C cable, it may refuse to charge, transfer files, or connect to a computer. You plug it in, but nothing happens. In most cases, the issue is caused by dust inside the port, a faulty cable, or incorrect USB settings, and you can fix it without visiting a service center.
Why Your Realme 16 Is Not Detecting the USB-C Cable
- Dust or lint is blocking the USB-C port.
- The charging cable or adapter is damaged.
- USB mode is set incorrectly in the settings.
- The USB-C port is physically loose or worn out.
- A software bug is preventing proper USB detection.
Check and Clean the USB-C Port
Lint and debris often build up inside the charging port, especially if you carry your phone in your pocket. Even a small amount of dust can prevent the cable from making proper contact.
Turn off your Realme 16.
Inspect the USB-C port under bright light.
Use a wooden toothpick or compressed air to gently remove any visible debris.
Avoid using metal objects, as they can damage the internal connectors.
Try a Different Cable and Charger
Sometimes the problem is not the phone but the cable itself. Cheap or worn-out cables may stop working suddenly.
Plug in a different USB-C cable, and then connect it to a reliable wall adapter.
If possible, test your current cable with another device.
If the new cable works, replace the old one immediately.
Check USB Preferences
Your phone may be charging but not recognizing file transfer because the USB mode is set to charge only. Adjusting the USB preference can restore proper detection.
Open Settings, and then tap About phone.
Tap Status, and then tap USB.
Select File transfer if you are connecting to a computer.
If you do not see USB options, connect the cable first and wait for the notification panel to show USB preferences.
Restart Your Phone
A quick restart refreshes system services that manage USB connections. This simple step can fix minor detection bugs.
Press and hold the Power button, and then tap Restart.
Wait for the device to boot up fully.
Reconnect the USB-C cable and test it again.
Check for Software Updates
Software updates often fix connectivity bugs and hardware compatibility issues. Installing the latest update may resolve persistent USB detection problems.
Open Settings, and then tap Software update.
Tap Check for updates, and then download and install any available update.
Keeping your Realme 16 updated ensures better stability and improved hardware communication.
If your Realme 16 still does not recognize the USB-C cable after trying these steps, the charging port may be physically damaged and require professional repair. In most cases, though, cleaning the port or replacing the cable solves the problem quickly.
