One AirPod not charging usually means either a dirty charging contact, a problem with the case itself, or a battery that has worn out

When one AirPod won't charge while the other does, the issue is almost always physical — dirt or corrosion blocking the connection between the AirPod and the case, a faulty charging port in the case, or occasionally a battery that has reached the end of its life. The good news is that you can test and fix most of these problems yourself in a few minutes without opening anything.

The reason one AirPod fails while the other charges normally is that each AirPod has its own charging contact and its own battery. They sit in separate slots in the case, so a problem in one slot does not affect the other. This also means you can narrow down whether the problem is the AirPod itself, the case, or the cable connecting the case to power.

Key Takeaways

  • Dirty charging contacts on the AirPod or inside the case are the most common cause — clean both with a dry cotton swab or soft cloth.
  • Swap the non-charging AirPod to the other slot in the case to test whether the problem follows the AirPod or stays in that slot.
  • If the AirPod charges in the other slot, the case itself has a dirty or damaged charging port and needs cleaning or repair.
  • If the AirPod still will not charge in either slot, the battery inside that AirPod has likely failed and the AirPod needs replacement.
  • Resetting the AirPods by holding the button on the back of the case for 15 seconds can sometimes restore charging when contacts are clean.

Clean the charging contacts on both the AirPod and the case

The charging contacts are small gold or copper dots on the bottom of each AirPod and matching dots inside each slot of the case. When dust, earwax, or moisture collects on these contacts, the electrical connection breaks and charging stops. This is the most common reason one AirPod will not charge.

To clean them, use a dry cotton swab or the corner of a soft, lint-free cloth. Gently rub the bottom of the non-charging AirPod where you see the metal contacts. Then use a fresh swab to clean the corresponding slot inside the case — the two small dots where that AirPod sits. Do not use water, rubbing alcohol, or any liquid, as moisture can damage the battery or internal circuits. Dry contact cleaning only.

After cleaning, place the AirPod back in its slot and close the case for 30 seconds, then open it and check whether the LED light on the front of the case shows the AirPod is charging. If the light turns amber or green, the contacts were the problem and charging has resumed.

Test whether the problem is the AirPod or the case by swapping slots

Each AirPod has its own charging slot in the case, and each slot has its own charging port. By moving the non-charging AirPod to the other slot, you can tell whether the problem is with that specific AirPod or with the case itself.

Place the AirPod that will not charge into the opposite slot — if it normally goes in the right slot, put it in the left slot instead. Close the case for a minute, then open it and look at the LED light. If the AirPod now charges in the new slot, the original slot has a dirty or damaged charging port. If the AirPod still will not charge no matter which slot you use, the problem is the AirPod's battery itself.

Fix a dirty charging port in the case

If the AirPod charges when you move it to the other slot but not in its original slot, the charging port in that slot is blocked or corroded. This is usually caused by dust, lint, or dried earwax inside the case.

Use a dry cotton swab to gently clean inside the slot where the AirPod normally sits. You are looking for the two small metal contacts at the bottom of the slot. Swab around them carefully to remove any visible debris. If the contacts look discolored or corroded (dull or greenish instead of shiny), you may need to rub more firmly, but do not scratch them.

After cleaning, place the AirPod back in its original slot and test again. If it still does not charge, the charging port may be physically damaged and the case may need to be replaced. Apple offers case replacement through their support site or at an Apple Store.

Reset the AirPods if contacts are clean but charging still fails

Sometimes the AirPods and case lose their charging communication even when the contacts are clean. A reset can restore this connection without erasing your pairing with your phone or computer.

With the AirPods in the case, locate the small button on the back of the case (not the front where the LED is). Press and hold this button for 15 seconds until the LED light flashes amber and then white. Release the button. The AirPods are now reset and will charge normally again in most cases.

After the reset, place both AirPods in the case and let them charge for at least 15 minutes. Then open the case near your phone or computer and they will re-pair automatically. Check that both AirPods show as connected and fully charged.

When the battery inside the AirPod has failed

If the AirPod will not charge in either slot and the contacts are clean, the rechargeable battery inside that AirPod has likely reached the end of its life or has failed. AirPod batteries typically last between three and five years of regular use before they stop holding a charge.

Once a battery fails, it cannot be repaired at home — the AirPod must be replaced. You can purchase a replacement AirPod from Apple or an authorized retailer. Apple also offers a mail-in repair service if your AirPods are still under warranty or covered by AppleCare.

In the meantime, you can still use the one working AirPod by itself. Most devices allow single-AirPod use, though you will hear audio in only one ear. The non-charging AirPod can stay in the case as a backup until you replace it.

Prevent future charging problems

Keep the case and AirPods dry and away from moisture. Wipe the outside of the case occasionally with a dry cloth, and store it in a clean pocket or bag rather than on a surface where dust can settle. If you use your AirPods during exercise or in humid environments, let them dry completely before placing them in the case.

Check the charging contacts every few months — a quick swab with a dry cotton swab takes 30 seconds and prevents most charging problems before they start. If you notice one AirPod charging slower than the other, clean the contacts when ready rather than waiting until one stops charging entirely.

Frequently Asked Questions

How do I know if the LED light means the AirPod is charging?

When an AirPod is charging, the LED on the front of the case shows amber. When fully charged, it turns green. If the light does not change when you place the AirPod in the case, the charging connection is broken. The light should change within a few seconds of closing the case.

Can I use one AirPod while the other charges?

Yes. You can take one AirPod out and use it alone while the other stays in the case to charge. Most devices automatically switch to single-AirPod mode. The audio will play in only one ear, but the connection remains stable.

What if cleaning the contacts does not work?

If the contacts are visibly clean and the AirPod still will not charge in either slot, the battery inside the AirPod has likely failed. The AirPod will need to be replaced through Apple or an authorized retailer. If the AirPod charges in one slot but not the other, the case's charging port is damaged and the case needs replacement.

Is it safe to use rubbing alcohol to clean the contacts?

No. Rubbing alcohol can seep into the AirPod and damage the battery or internal circuits. Use only a dry cotton swab or dry cloth. If moisture has already entered the AirPod, let it air-dry in a warm, dry place for 24 hours before trying to charge it again.

How long should I let the AirPods charge after cleaning?

After cleaning the contacts, close the case for 30 seconds to test whether charging has resumed. If it has, let both AirPods charge for at least 15 minutes before using them. A full charge from empty takes about 60 minutes.
