The most common reasons your AirPods case stops charging
An AirPods case that won't charge usually has one of three problems: the charging port is blocked or corroded, the battery inside the case has failed, or the cable or power adapter you're using is faulty. Start by checking the port itself — look inside the small Lightning connector on the bottom of the case with a flashlight. You'll often see lint, dust, or white corrosion buildup that prevents the cable from making contact.
If the port looks clean and a different cable charges other devices fine, the problem is likely inside the case. The battery that powers your AirPods can degrade over time, especially if the case has been dropped, exposed to moisture, or charged constantly for years. Unlike your iPhone, you cannot replace just the battery in an AirPods case — the entire case must be replaced.
Key Takeaways
- Lint and corrosion in the Lightning port are the most fixable reason a case won't charge; clean it gently with a dry cotton swab or soft brush.
- If the port is clean and another cable works on other devices, the internal battery in the case has likely failed and cannot be repaired.
- Water damage or repeated drops can kill the case battery even if the case looks fine on the outside.
- Apple will replace an out-of-warranty case for a flat fee, usually between $50 and $70 depending on your AirPods model.
How to clean the charging port safely
The Lightning port on the bottom of your case is small and straightforward to clog. Grab a dry cotton swab or a soft-bristled toothbrush and gently brush inside the port to dislodge dust and lint. Do not use water, rubbing alcohol, or compressed air — water can seep into the case and damage the battery, alcohol can corrode the metal contacts, and compressed air can push debris deeper into the port instead of out.
After cleaning, wait a few minutes and try charging again with the original Apple cable if you have it. If you've been using a third-party cable, switch to an Apple USB-C to Lightning cable or the USB-C power adapter that came with your AirPods. Some third-party cables have slightly different pin spacing and won't seat properly in the port.
Testing whether the problem is the cable or the case
Before you assume the case is broken, rule out the cable. Plug the cable into your iPhone, iPad, or another Apple device and see if it charges normally. If it does, the cable is fine and the problem is in the case itself. If the cable doesn't charge other devices either, replace it with an Apple USB-C to Lightning cable — these cost about $20 and are sold at most electronics retailers.
You can also test the case by borrowing a friend's AirPods case and trying to charge it with your cable. If their case charges fine, your case battery has failed. If their case also won't charge, your cable is the problem.
What water damage looks like inside the case
If your AirPods case has been dropped in water, rained on, or exposed to high humidity, moisture can corrode the battery contacts inside. You may see white, green, or blue discoloration around the charging contacts at the bottom of the case, or inside the case where the AirPods sit. This corrosion prevents electrical contact and the case will not charge.
If you suspect water damage, do not attempt to charge the case — this can short the battery and create a safety risk. Let the case dry completely in a warm, dry place for at least 48 hours, then try charging. If corrosion is visible, the case will need to be replaced.
When to replace the case instead of troubleshooting
If you've cleaned the port, tested with a different cable, and the case still won't charge, the internal battery has failed. Apple will replace the case under warranty if your AirPods are less than one year old and the damage is not from physical impact or liquid exposure. If your AirPods are older or the damage is visible, Apple charges a flat fee to replace the case — usually $49 to $69 depending on your model.
You can start a replacement through Apple's website, by visiting an Apple Store, or by calling Apple Support at 1-800-MY-APPLE. Have your AirPods serial number ready; you can find it in Settings > Bluetooth on your iPhone, then tap the information icon next to your AirPods name. The replacement case typically arrives within 5 to 7 business days.
How to avoid case battery failure in the future
The case battery lasts longest when you avoid extreme temperatures, keep the case dry, and don't leave it plugged in constantly. Store your AirPods in a cool, dry place — not in a car on a hot day or in a bathroom where humidity is high. If you charge the case overnight regularly, consider unplugging it once it reaches 100 percent, since trickle charging (staying plugged in after full) can degrade the battery over time.
If you drop your AirPods or the case gets wet, dry it when ready and let it sit for 24 hours before charging. Inspect the port every few months and clean it with a dry swab if you see dust buildup. These small habits can add years to your case's life.
Frequently Asked Questions
Can I use a different brand cable to charge my AirPods case?
Third-party USB-C to Lightning cables sometimes work, but Apple's cable is designed to fit the port precisely. If a third-party cable doesn't charge your case after cleaning the port, switch to an official Apple cable before assuming the case is broken.
Is it safe to charge my AirPods case overnight?
It's safe in the short term, but charging overnight regularly can wear out the battery faster. If you charge every night, unplug the case once it reaches 100 percent to extend its lifespan.
What's the difference between a case that won't charge and a case that won't hold a charge?
A case that won't charge has a port or connection problem. A case that won't hold a charge charges fine but drains quickly — this is normal battery aging and means the case needs replacement.
Can Apple fix my case if I damaged it by dropping it?
Apple will replace it for a fee even if there's physical damage, but the cost is the same whether damage is visible or not. Accidental damage is not covered under warranty, so you'll pay the out-of-warranty replacement price.
