How to troubleshoot Ledger Nano X battery issues - marseausylvius/Ledger-Device-Fixes-and-Solutions GitHub Wiki

If you encounter error messages such as “Battery cannot charge” or “Battery problem: charging stopped,” or if you’re experiencing battery charging issues with your Ledger Nano X, this article will guide you through troubleshooting these issues.

 Important Information

To function properly, a battery must operate within a certain temperature range, usually between 0°C and 35°C. This applies to the Ledger Nano X as well as most electronic devices such as hardware wallets, phones, computers, etc. However, if the battery is completely discharged, its operating temperature may be affected. In some cases, the battery may fail to recharge if the temperature is too low.

Troubleshooting the “Error: battery cannot charge” or “Battery problem: charging stopped” issue

 Note: Do not unplug the device during this process.

  1. Turn on the device.
  2. Hold both buttons to open the Control Center.
  3. Navigate to Settings.
  4. Press both buttons to access General.
  5. Navigate to Battery Saver and select Never Power Off.
  6. Let your device lock after a period of inactivity.
  7. Wait for 10 minutes on the PIN entry screen.
  8. Unplug and reconnect your device. Check if the issue persists or if the device is charging.
  9. If the charging resumes, leave the device to charge for at least 20 minutes before unplugging it.

 Still not solved?

If the above steps do not work, try warming up your device’s battery. To do so, you can:

  • Hold it in your hands.
  • Increase the room temperature.
  • Blow warm air near your device, but be careful not to do this too closely to avoid damaging the product.

The optimal operating temperature for a fully discharged battery is 30°C.

Advanced Troubleshooting

  1. Press both buttons on your Ledger Nano X to dismiss the error message.

  2. Let the device charge for 20 minutes without any manipulation. A screen saver will appear in the meantime.

  3. Once the charging period is over, press the left button once to exit the screen saver mode, then hold both buttons down for 3 seconds to access the control center.

  4. Select “Power Off” by pressing the right button once. Turn off the device by pressing both buttons simultaneously. The device will restart after a few seconds.

    The device may need several on/off cycles to work in the case of a completely discharged battery. If the procedure worked, the battery warning message should no longer appear, and the logo in the upper right corner will change from a plug icon to a charging battery icon. You should now see the welcome screen. Leave the device connected and charging for about 8 hours to ensure the battery is fully charged.
