What does it mean when my wireless charger is blinking yellow?

A blinking yellow light on a wireless charger usually signals a warning or fault rather than normal charging. It often points to misalignment, overheating, a foreign object detected, or a power delivery issue. Check the setup and consult your charger’s manual for device-specific codes.

Interpreting a blinking yellow indicator

While there is no universal standard, these are the most frequently observed explanations across popular charger brands:

• Misalignment or off-center placement: the device isn’t properly aligned with the charging coil.


• Overheating: the charger or the device is too hot and safety features are limiting charging.


• Foreign object detection (FOD): metal objects or materials in contact with the pad trigger a warning.


• Power input or cable issues: a loose cable, damaged adapter, or insufficient wattage can cause the light to blink.


• Incompatibility or case issues: a thick or metal case, or an unsupported device, may trigger a warning signal.


• Software/firmware or device-specific codes: some chargers use yellow blinking to indicate a required firmware update or a fault state.

If the indicator is blinking yellow, approach the situation with a systematic check of alignment, temperature, objects on/near the pad, and the power supply.

Troubleshooting steps

Use these steps to identify and fix common causes of a blinking yellow light.

1. Power cycle: unplug the charger, wait 10–30 seconds, and plug it back in to reset the electronics.


2. Check the power supply: use the charger’s recommended adapter and a stable outlet; avoid extension cords where possible.


3. Reposition the device: place the phone or item centered on the pad; remove thick or metal-heavy cases if necessary.


4. Remove obstructions: clear away metal objects or accessories near the charging surface; ensure nothing is on top of the pad.


5. Check for heat: if the charger or device is hot, allow it to cool before attempting to charge again.


6. Try a different device or cable: test with another compatible device or cable to isolate whether the issue is with the charger or the device.


7. Update firmware/software: if your charger or its companion app offers firmware updates, install them and ensure the connected device software is current.

Conclusion: If the blinking yellow light persists after these steps, consult the user manual for brand-specific codes or contact customer support for further guidance or warranty options.

Brand-specific notes

Indicator colors and blinking patterns vary by manufacturer. Some brands reserve amber/yellow for standby or overheating warnings, others use it to indicate a fault that requires a reset or service. Always refer to your charger’s documentation or support site for exact meanings.

Summary

A blinking yellow light on a wireless charger typically signals a non-critical warning related to misalignment, heat, foreign objects, or power delivery. Follow a structured troubleshooting approach—adjust alignment, cool the device, check cables and power, and remove obstructions—and consult the manual or support if the light continues to blink.

Common causes and solutions

• Misalignment: The device isn't positioned correctly on the charging pad. 
  • Solution: Remove your phone and place it back on the pad, centering it over the charging coil. 
• Overheating: The charger or device has become too hot. 
  • Solution: Remove the device from the charger and give both time to cool down. Make sure the charger isn't on a soft surface or in direct sunlight. 
• Incompatible or weak power adapter: The wall adapter isn't providing enough power to charge the device wirelessly. 
  • Solution: Use the original adapter that came with your charger or a more powerful one (e.g., one that supports Quick Charge). 
• Foreign object detection: A metallic object, like a coin, keys, or even a thick phone case, is between the charger and your phone. 
  • Solution: Remove any case or foreign objects and try again. 
• Faulty cable or charger: There is an issue with the charging cable or the charger itself. 
  • Solution: Check the cable for damage and ensure it's firmly plugged into the adapter and the pad. If the problem persists, there may be a hardware issue with the charger. 
• Software glitches: Rarely, a software issue on the phone or charger can cause this. 
  • Solution: Restart your phone or check for any firmware updates for your wireless charger.
