An LED light that doesn’t turn red, rapidly flashing low battery warning, or sudden shutdowns during use are indicators of charging problems. Pinpointing the root cause is key before attempting any repair solutions.

LG TONE Style HBS SL5 Not Charging

Charging issues in the LG SL5 headphones commonly stem from faulty or dirty charging pins, software glitches, broken charging ports, loose cable connections, or worn out batteries. A thorough inspection of the hardware and software troubleshooting can reveal the factors impairing normal charging function. With the right diagnosis, this charging problem can be fixed using simple cleaning tools, cable adjustments, or firmware updates.

This guide will take you through systematic troubleshooting steps to diagnose an LG TONE Style HBS-SL5 unit that is not charging. Follow each solution closely:

Inspect The Charging Port

Examine the micro USB charging port located on the underside of the right headphone. Look for any debris, damage, or bent pins that may be obstructing the port. Use a soft-bristled brush and compressed air to clear any dirt buildup. A broken charging port will need professional repair.

To inspect the charging port:

  1. Turn the right headphone over to access the charging port.
  2. Check for any debris or dust blocking the port.
  3. Use a brush and compressed air to clean the port if required.
  4. Examine the port for any physical damage or bent pins.

Inspecting the charging port will reveal if dirt, damage, or defects are impeding charging.

Try Different Charging Cables

Faulty charging cables are a common reason for devices not charging properly. Try using alternative micro USB cables to see if the headphones will charge. Avoid using third-party low quality cables. Test different wall adapter plugs, too, if needed.

To try different charging cables:

  1. Connect your LG SL5 to a wall charger with the original charging cable.
  2. If it still won’t charge, swap out the charging cable and try again.
  3. Repeat with at least 2-3 replacement micro USB cables.
  4. Test different compatible wall adapters as well.

Changing cables and wall adapters isolates charging hardware issues efficiently.

Check For Loose Connections

Loose connections between the charging cable, adapter, and headphones can stop the current flow and prevent charging. Carefully check that all connections are securely plugged in. Wiggle the cable lightly to check for loose ports.

To check for loose connections:

  1. Inspect the micro USB charging cable connection at both ends.
  2. Check that the adapter is firmly plugged into the wall socket.
  3. Wiggle each connection point slightly to test for tightness.
  4. Reconnect components firmly if any looseness is found.

Snug connections are vital for uninterrupted power transfer during charging.

Reset The Headphones

Resetting the headphones to factory settings can fix software glitches that may be preventing normal charging. It forces a reboot and clears any corrupt data.

To reset the headphones:

  1. Locate the reset button on the underside of the right earcup.
  2. Press and hold the reset button for 5-7 seconds using a paper clip.
  3. Try connecting the headphones for charging after resetting.

Resetting often resolves charging problems caused by buggy software and system crashes.

Update Firmware

Install the latest firmware updates for your LG SL5 model. Firmware fixes known bugs and optimizes charging performance. Update using the LG Tone & Talk companion app.

To update firmware:

  1. Install the Tone & Talk app on your smartphone.
  2. Connect and pair the headphones with the app.
  3. Check for any pending firmware updates.
  4. Download and install the latest firmware version.

Firmware updates specifically target charging and battery issues in wireless headphones.

Thoroughly inspecting the hardware and updating software are key first steps to diagnosing charging problems on the LG TONE Style HBS-SL5. If the unit is still under warranty, contact LG support for replacement options if you cannot resolve the issue on your own. With consistent troubleshooting, you can pinpoint why your headset won’t charge and take appropriate measures to get it working optimally again.


  1. Q: Why won’t my wireless headphones charge when plugged in?

    A: If your wireless headphones don’t charge, it could be due to a loose charging cable connection, worn charging port, dirty or broken charging pins, discharged battery, or a need to reset the headphones. Inspect connections, clean the port, try replacing cables, and reset the headphones to factory settings.

  2. Q: How can I get my Bluetooth earbuds to start charging again?

    A: First, clean the earbud charging contacts gently with a cotton swab and rubbing alcohol. Make sure the charging cable is properly inserted into the earbud case and wall outlet. Try different cables and chargers to isolate the issue. Also, update your earbud firmware and reset them. If problems persist, the battery may need replacement.

  3. Q: Why is only one side of my wireless headphones charging when plugged in?

    A: If only one earbud or side is charging, it usually points to a connection problem with the other side’s charging port or internal contacts. Check for debris in the problem earbud’s port, clean the pins, and make sure the earbuds make a secure connection with the charging case. The battery or charging mechanism may be damaged on the non-charging side.
