The left AirPod usually won't charge because of a poor connection between the bud and the case, debris blocking the charging pins, or a drained case battery
When only your left AirPod sits in the case but doesn't charge, the problem is almost always one of three things: the metal charging pins on the bud or inside the case are dirty or misaligned, the case itself has run out of battery, or the left bud has a hardware fault. Start by checking the simplest cause first — a dirty connection — because it fixes nine times out of ten without any tools or waiting.
The charging pins are tiny metal contacts on the bottom of each AirPod and inside the case. They have to touch perfectly for power to flow. Even a speck of lint, earwax, or dried sweat breaks that connection. Your right AirPod charges fine because it may have better contact by chance, or because you've been putting it in a slightly different position.
Key Takeaways
- Clean the charging pins on the bottom of your left AirPod and inside the case with a dry cotton swab, because dirt is the most common reason charging fails.
- Make sure your AirPods case itself has battery by plugging it in for 15 minutes, because a dead case cannot charge either bud.
- Check that the left AirPod sits flat in its slot and doesn't rock side to side, since a loose fit prevents the pins from making contact.
- If cleaning and repositioning don't work, try resetting your AirPods by holding the setup button on the case for 15 seconds until the light flashes amber.
Clean the charging pins on both the bud and the case
Take a dry cotton swab and gently wipe the bottom of your left AirPod where you see the two small metal dots. Do the same inside the case where those dots sit — you'll see two small metal circles recessed into the plastic. Don't use water, rubbing alcohol, or any liquid, because moisture can damage the electronics inside. A dry swab is enough to remove the buildup that blocks charging in most cases.
Wipe slowly and let the swab dry completely before putting the AirPod back in the case. If you see visible debris like lint or earwax, you may need to repeat this two or three times. Some people find a soft toothbrush works better than a swab for getting into the corners of the case slot, but be very gentle — the pins are fragile.
Confirm your case has battery before troubleshooting the bud
A dead case cannot charge either bud, so plug your case into a USB-C or Lightning cable (depending on your AirPods model) and leave it connected for at least 15 minutes. The light on the front of the case should turn on — usually amber or green. If the light doesn't appear after 15 minutes, your case battery may be dead and the case itself may need replacement.
While the case charges, don't put your AirPods inside it. After 15 minutes, unplug the case and wait a few seconds, then place your left AirPod in the left slot. The light should flash or change color to show charging has started. If it doesn't, move to the next step.
Check that the AirPod sits flat and doesn't rock in the slot
Remove your left AirPod and look at the slot it sits in. Place the bud back in slowly and press down gently until you hear or feel a small click. The bud should not rock side to side or sit at an angle. If it does, the charging pins aren't making full contact with the case pins, and no amount of waiting will charge it.
Sometimes the slot itself gets slightly bent or warped, especially if you've dropped the case or sat on it. If the bud won't sit flat no matter how you position it, the case slot may be damaged and the case may need replacement. Try placing the bud in the right slot to see if it sits flat there — if it does, the left slot is the problem.
Reset your AirPods to clear a software glitch
Occasionally the charging system gets stuck in a confused state even though the hardware is fine. To reset, place both AirPods in the case and close the lid. Wait 30 seconds. Then open the lid, locate the small setup button on the back of the case, and hold it down for 15 seconds. The light on the front will flash amber, then white. Release the button and wait another 30 seconds.
After the reset, open the case and check whether the left AirPod now charges. The reset erases the pairing with your phone, so you'll need to pair them again by going to Bluetooth settings on your device and selecting your AirPods from the list. This step fixes charging problems caused by software bugs about half the time.
Try charging the left AirPod in the right slot
Place your left AirPod in the right slot of the case instead of the left slot. If it charges there, the left slot is damaged or misaligned and the case needs replacement. If it still doesn't charge in the right slot, the problem is with the AirPod itself, not the case.
This test takes 10 minutes and tells you exactly what's broken. It's worth doing before you decide whether to replace the case or the individual bud, because Apple charges different amounts depending on which part is faulty.
When to replace the case or the AirPod
If your left AirPod charges fine in the right slot but not in the left slot, the left slot is damaged and you need a new case. If the left AirPod won't charge in either slot, the bud itself has a hardware problem and you need a replacement AirPod. If the case won't charge at all and the light never appears, the case battery is dead and the case needs replacement.
Apple sells individual replacement AirPods and cases through their website and in stores. Bring your case and AirPods with you if you visit a store, because staff can test them to confirm which part is faulty before you buy a replacement. If your AirPods are still under the one-year warranty that comes with purchase, replacement may be free.
Frequently Asked Questions
Can I use my AirPods while the case is charging?
Yes. Once your AirPods are fully charged, you can take them out and use them while the case itself charges. The case charges independently of the buds. However, if your left AirPod isn't charging in the case, don't remove it to use — it will drain completely and you won't be able to charge it until you fix the underlying problem.
What if I cleaned the pins and reset the AirPods but the left one still won't charge?
The left AirPod likely has a hardware fault or the case slot is damaged. Test by placing the left AirPod in the right slot — if it charges there, replace the case; if it doesn't charge in either slot, replace the individual AirPod. Contact Apple support or visit an Apple Store with your case and buds to confirm which part is faulty.
Is it safe to use rubbing alcohol to clean the charging pins?
No. Rubbing alcohol can seep into the electronics and cause corrosion or short circuits. Use only a dry cotton swab. If the pins are very dirty, you can slightly dampen the swab with distilled water, but let it air-dry completely before putting the AirPod back in the case.
Why does my right AirPod charge but not the left?
The right slot and bud are probably making better contact by chance, or the right bud is cleaner. Start by cleaning both the left AirPod and the left slot with a dry swab. If that doesn't work, test the left AirPod in the right slot to find out whether the problem is the bud or the case slot.
How long should I wait after putting my AirPod in the case before I check if it's charging?
The light should appear within a few seconds of placing the AirPod in the case. If no light appears after 10 seconds, the connection isn't working. Don't wait longer — waiting won't fix a bad connection. Move on to cleaning the pins or testing the bud in the other slot.
