The most common reason: dirt blocking the charging contacts

When one AirPod stops charging, the problem is usually a thin layer of debris — earwax, lint, dust, or dried sweat — sitting on the metal charging contacts inside the case. These contacts are tiny and need to touch the matching contacts on the AirPod itself. Even a film you cannot see with your naked eye will break that connection.

The fix is straightforward: use a dry cotton swab or a soft, dry cloth to wipe both the charging contacts on the AirPod and the matching contacts inside the case. Look for the small metal dots or rectangles. Wipe gently in one direction rather than scrubbing. Let both dry completely before putting the AirPod back in the case.

This solves the problem in roughly seven out of ten cases where one AirPod will not charge. If it does not, move to the next section.

Key Takeaways

  • Dirt on the charging contacts is the most common cause — wipe them with a dry cotton swab and let them dry completely.
  • If cleaning does not work, try resetting the AirPods by holding the setup button on the case for 15 seconds until the light flashes amber, then white.
  • A battery that has failed inside one AirPod cannot be fixed at home and requires a replacement from Apple or an authorized repair shop.
  • If the case itself is not charging, the problem is usually the case battery or the Lightning port, not the individual AirPods.

Reset the AirPods when cleaning does not work

If the contacts are clean and one AirPod still will not charge, the next step is a factory reset. This clears out any software glitch that might be preventing the AirPod from recognizing the charge.

Put both AirPods in the case and close the lid. Open the case and look for the small button on the back. Press and hold it for about 15 seconds. You will see the light inside the case flash amber, then white. When it flashes white, the reset is complete. Forget the AirPods from your phone's Bluetooth settings and pair them again as if they were new.

After the reset, put the AirPod that was not charging back in the case for at least 30 minutes and check whether it charges. The light next to the AirPod should turn green when it is fully charged.

How to tell if the battery inside the AirPod has failed

If the contacts are clean, you have reset the AirPods, and one still will not charge, the battery inside that AirPod has likely failed. Lithium batteries — the kind in AirPods — can stop holding a charge after a few years of use, especially if the AirPods have been exposed to heat or moisture.

You can confirm this by checking the battery status on your phone. Open the Batteries widget (on iPhone, swipe right from the home screen and scroll down; on Android, this varies by phone). If one AirPod shows 0% and stays at 0% even after sitting in the case for an hour, the battery is dead.

A failed battery cannot be replaced at home. You will need to contact Apple Support, visit an Apple Store, or take the AirPods to an authorized repair shop. Apple typically charges a flat fee for a replacement AirPod rather than a repair. The cost varies, but expect to pay between $50 and $100 for a single replacement AirPod.

Distinguish between a dead AirPod and a dead case

It is straightforward to confuse a charging problem with the AirPod itself with a charging problem with the case. If the case is not charging, the individual AirPods inside it cannot charge either, even if they are working perfectly.

To tell the difference: put the AirPod that is not charging into the case, close the lid, and wait 10 minutes. Then open the case and look at the light. If the light is off or red, the case battery is low or dead. If the light is green or amber, the case has power. If the light is green and the AirPod inside still shows 0% in the Batteries widget, the problem is the AirPod, not the case.

If the case is not charging, check the Lightning port at the bottom for debris, lint, or corrosion. Clean it gently with a dry cotton swab. If the case still will not charge after cleaning, the port or the case battery may be damaged and will need replacement.

Why moisture and heat damage AirPods

AirPods are not waterproof, though newer models are water-resistant. If one AirPod has been exposed to sweat, rain, or water — even briefly — moisture can corrode the charging contacts or damage the battery inside. Heat from a car dashboard, a dryer, or direct sunlight can also degrade the battery over time.

If you know one AirPod has gotten wet, remove it from the case when ready and let it air dry for at least 24 hours in a warm, dry place. Do not use heat like a hair dryer. Do not put it in rice or silica gel — these can leave residue on the contacts. Once it is completely dry, try charging it again.

If the AirPod was wet and will still not charge after drying, the damage is likely permanent and replacement is the only option.

When to contact Apple or a repair shop

Contact Apple Support or visit an Apple Store if any of these are true: the AirPod will not charge after cleaning and resetting, the case will not charge even after cleaning the Lightning port, or one AirPod has been exposed to water and will not charge after drying.

Have your proof of purchase or serial number ready. You can find the serial number by going to Settings > Bluetooth on your phone, tapping the information icon next to your AirPods, and looking for the serial number. Apple uses this to check whether your AirPods are still under warranty. If they are, replacement is usually free. If they are not, you will pay a flat fee for a replacement AirPod or case.

Frequently Asked Questions

Can I use my AirPod while the other one charges?

Yes. One AirPod will work on its own for calls, music, and audio. The battery in a single AirPod typically lasts 5 to 6 hours depending on the model and volume level. You can use it while the other charges in the case.

What does the amber light mean when I reset my AirPods?

Amber means the reset is in progress. Keep holding the button until the light turns white, which signals the reset is complete. If the light goes out before turning white, you did not hold the button long enough — try again.

Is it normal for one AirPod to die faster than the other?

Slightly uneven battery drain is normal, but if one AirPod consistently dies much faster, the battery inside it may be failing. Clean the contacts first, then monitor the battery levels over a few charging cycles. If the gap widens, replacement is likely needed.

Will AppleCare cover a single AirPod that will not charge?

AppleCare covers accidental damage and hardware failure. If the AirPod will not charge due to a manufacturing defect or accidental damage, AppleCare will cover replacement. If the battery straightforward wore out after years of use, it may not be covered, though Apple sometimes replaces it at a reduced cost.
