Some of the most common culprits for a Note 12 refusing to charge include:

  • Loose charging cable – The charging cable may not be fully inserted into the phone. Ensure it’s securely connected.
  • Faulty charging cable – Fraying or damage to cables prevents proper charging. Try another cable to isolate issue.

  • Software glitch – Bugs and system issues can temporarily disrupt charging functions. Restarting the phone often resolves this.
  • Charging port damage – Debris in port or physical port damage from drops can prevent charging entirely until cleaned or repaired.
  • Third-party charger – Avoid using third-party wall adapters or wireless chargers which may not be fully compatible with the Note 12.
  • Restrictive battery settings – Battery saver modes or other settings may temporarily limit charging rate or disable charging.

Troubleshooting and Fixes for a Note 12 That Won’t Charge

If your Note 12 isn’t charging properly, you can try any of these subsequent troubleshooting procedures that’s applicable to your scenario:

1. Inspect Cables and Ports

Carefully check that cables are undamaged and fully inserted into ports without debris or obstructions present.

Inspecting cables and ports is necessary when dealing with charging issues on a Redmi Note 12 because damaged or faulty cables can result in a poor electrical connection, leading to slow or ineffective charging.

Additionally, examining the ports ensures there is no debris or corrosion preventing a secure connection between the cable and the device, which can also affect charging performance.

2. Use Alternative Cable

Test charging with a different certified cable to isolate whether issue is with the cable or phone itself.

Using an alternative cable can help when dealing with charging issues on a Xiaomi Redmi Note 12 by eliminating the possibility of a faulty or damaged cable as the root cause of the problem. If the original cable is defective, switching to a different, known-working cable can often resolve the issue and ensure a stable and efficient charging process.

3. Toggle Airplane Mode

Turn on Airplane mode temporarily to eliminate possibility of software conflicts preventing charging.

There are two ways to toggle Airplane mode on your Xiaomi Redmi Note 12:

Method 1: Using the notification shade

When Airplane mode is on, all wireless connections on your phone will be disabled, including Wi-Fi, Bluetooth, and cellular data. This can be useful if you are on a plane or in a place where you do not want to be disturbed by notifications or calls.

To turn Airplane mode off, simply follow the same steps and toggle the switch to the off position.

Here are some things to keep in mind when using Airplane mode on your Xiaomi Redmi Note 12:
