One AirPod not charging usually means a dirty charging contact, a worn-out battery, or a connection problem between the bud and case

When one AirPod won't charge while the other does, the problem is almost always physical — dirt on the metal contacts, a battery that has worn out after hundreds of charge cycles, or a loose connection inside the case. The good news is that most of these issues are fixable at home without opening anything up. The bad news is that if the battery itself has failed, you will need to replace that individual bud.

Start by checking the obvious: whether the case itself is charged, whether you are placing the AirPod in the correct slot, and whether the charging contacts are actually touching. Most people skip these steps and jump straight to assuming the AirPod is broken.

Key Takeaways

  • Dirty charging contacts are the most common reason one AirPod won't charge — clean the metal pins on both the AirPod and the case slot with a dry cotton swab.
  • The charging case must have battery power itself; if both AirPods fail to charge, the case is the problem, not the buds.
  • Resetting your AirPods by holding the setup button for 15 seconds can fix connection issues that prevent charging from registering.
  • If cleaning and resetting do not work, the battery inside that AirPod has likely failed and the bud will need to be replaced.

Check the charging case battery first

Before you assume the AirPod is broken, confirm that the case itself has power. Look at the LED light on the front of the case: if it is off or red, the case is dead and neither AirPod will charge. Plug the case into power using the Lightning cable (for older AirPods) or USB-C cable (for AirPods Pro 2 or AirPods Max) and wait at least 15 minutes.

If the case charges normally and the LED turns green, the case is fine. If the case will not charge at all, try a different cable and a different power outlet — the cable itself may be damaged. If the case still will not charge after trying multiple cables, the case battery has failed and you will need a replacement case.

Clean the charging contacts on the AirPod and case

Dirt, lint, and earwax buildup on the metal charging pins are the single most common reason one AirPod stops charging. The AirPod has three small gold or copper pins on the bottom. The case has matching pins inside each slot. If either set is dirty, the connection breaks and charging does not happen.

Use a dry cotton swab to gently wipe the three pins on the bottom of the AirPod. Do not use water, alcohol, or any liquid — moisture can damage the internal electronics. Then use a fresh dry swab to clean the pins inside the case slot where that AirPod sits. Look closely: you should see three small metal points. Wipe each one. Let everything air-dry for a minute, then place the AirPod back in the case and check the LED.

If the LED now shows green (charging) instead of amber (not charging), the problem was dirt. If it still shows amber, move to the next step.

Make sure the AirPod is seated correctly in the case

The AirPod must sit flat in its slot with the stem pointing down and the charging pins making full contact with the case pins. If you place it at an angle or upside down, it will not charge even though it looks like it is in the case.

Remove the AirPod and look at the slot. You should see three small metal pins. Now look at the bottom of the AirPod — you should see three matching pins. Place the AirPod into the slot so the pins line up and the bud sits flush. You should hear or feel a small click. Check the LED: it should turn amber (charging) or green (already charged).

Reset the AirPods to fix connection problems

Sometimes the AirPod and case lose their connection, and the case stops recognizing that the bud is inside. A reset clears this connection and forces them to pair again. This often fixes charging issues that are not caused by dirt or physical damage.

Place both AirPods in the case and close the lid. Wait 30 seconds. Open the lid and look for the small setup button on the back of the case — it is a tiny circular indent. Hold it down for 15 seconds until the LED flashes amber and then white. Release the button. The AirPods are now reset. Place them back in the case and check whether the LED shows charging.

After a reset, you will need to pair the AirPods with your device again. Go to your phone or computer's Bluetooth settings, forget the AirPods, then hold the setup button again until the LED flashes white. Your device should find them and pair automatically.

Check whether the battery inside the AirPod has failed

If the charging contacts are clean, the case has power, the AirPod is seated correctly, and a reset did not work, the rechargeable battery inside that AirPod has likely reached the end of its life. AirPod batteries typically last 300 to 500 full charge cycles — roughly two to three years of normal use. After that, the battery can no longer hold a charge.

You cannot replace just the battery; Apple does not sell individual batteries for AirPods. Your options are to replace the single AirPod through Apple (which costs money but is faster than buying a new pair) or to buy a replacement pair. Check Apple's website or visit an Apple Store to see the current cost for a replacement bud.

When to contact Apple Support

If your AirPods are still under the one-year limited warranty and you have not damaged them physically, Apple may replace the non-charging bud at no cost. Accidental damage — like water damage or a cracked case — is not covered by the standard warranty, though Apple offers AppleCare+ plans that do cover accidents.

Contact Apple Support through their website, by phone, or by visiting an Apple Store. Have your AirPod serial number ready; you can find it in Settings on your iPhone or Mac under Bluetooth, then tap the information icon next to your AirPods. Apple will ask you to describe the problem and may ask you to try a few troubleshooting steps before offering a replacement.

Frequently Asked Questions

Can I use one AirPod while the other charges?

Yes. If one AirPod is not charging, you can place it in the case and use the other AirPod alone. Most AirPods models support single-bud use. The charged AirPod will work for calls, music, and audio until its battery runs out, then you can swap.

What if both AirPods won't charge?

The problem is almost certainly the case, not the buds. Clean the charging pins inside both slots, make sure the case itself is charged, and try a different charging cable. If the case still will not charge the buds, the case battery has failed and needs replacement.

Does water damage prevent charging?

Yes. If an AirPod got wet, water may have corroded the charging pins or damaged the internal battery. Let it dry completely in a warm, dry place for 24 to 48 hours before trying to charge again. If it still will not charge after drying, water damage is likely permanent.

How long should AirPods take to charge?

A single AirPod typically charges fully in about 15 to 30 minutes in the case, depending on the model. If one AirPod is taking much longer than the other, the charging connection is probably poor — clean the contacts and reseat the bud.

Will Apple replace one AirPod if I lost the other?

Apple will sell you a replacement single AirPod, but it costs roughly half the price of a new pair. You cannot get a free replacement for a lost bud under warranty. If one is broken and the other is lost, you would need to buy a replacement pair.
