Left AirPod Not Charging? How to Find the Cause
Share
If your left AirPod won't charge, the problem is almost always the contact between the earbud and the case — not the earbud itself. Dirty charging contacts, an earbud that isn't clicked in quite right or a software glitch explain most cases, and those you can fix yourself. Only if the earbud still stays empty after cleaning and a reset while the right one charges normally is the left earbud's battery worn out — and you can replace it on its own: a single left AirPod costs from €33.80 with us.
One important distinction first: this article is about one earbud that won't charge. If neither earbud charges, the case is the suspect — read Charging case not charging? Here's what you can do.
First: establish what exactly is happening
Place both earbuds in the case and open the lid next to your iPhone. You'll see the battery percentage for each earbud.
| What you see | What it means |
|---|---|
| The left earbud doesn't appear in the overview | The earbud isn't making contact or isn't paired |
| The left percentage stays put while the right one rises | Charging-contact problem with the left earbud |
| Left charges to 100% but drains quickly | Worn battery in the left earbud |
| Neither earbud charges | Problem with the case, not the earbud |
Step 1: clean the charging contacts
At the bottom of the earbud's stem are metal charging contacts; at the bottom of each case slot sits the counterpart. A thin layer of earwax, dust or skin oil is enough to block charging.
- Wipe the contacts on the earbud clean with a dry microfibre cloth.
- Clean the bottom of the left case slot with a dry cotton swab. Rotate it gently, don't press hard.
- Never use liquid or metal objects.
Put the earbud back and see whether the charging behaviour changes. Our cleaning guide contains the full maintenance instructions.
Step 2: check that the earbud is seated properly
An AirPod should drop into the case with a light magnetic click. If it sits crooked or loose, there's no charging contact.
- Take the left earbud out and reseat it until you feel the click.
- Check that nothing is stuck in the slot (lint, sand, a bent edge of a sticker or cover).
- Using a case cover? Take it off for a moment — some covers keep the lid from closing fully, which stops charging.
Step 3: is the case itself actually charged?
A case with an almost empty battery sometimes charges the earbuds only partially or unevenly. Put the case on the cable for ten minutes and then check the percentages again. If you're unsure about the case, test with your iPhone's cable (or another cable you know works) and a different charger.
Step 4: reset the AirPods
Software glitches can stop one earbud from communicating correctly with the case, so it won't charge or won't appear in the battery overview.
- Forget the AirPods in your Bluetooth settings.
- Place both earbuds in the case, lid open, and hold the button on the back of the case until the light flashes amber and then white (AirPods 4 has no button; there you reset by double-tapping the front of the case).
- Pair the set again and check the battery overview.
When is the battery worn out?
AirPods batteries wear with every charge cycle — and the left and right earbuds rarely wear at the same rate. If this sounds familiar, the left earbud's battery is at the end of its life:
- The earbud does charge to 100%, but is empty within an hour while the right one lasts for hours.
- The earbud cuts out mid-conversation and constantly needs to go back into the case.
- Even after cleaning and a reset, the charging behaviour remains unpredictable.
Replacing the battery on its own is practically not an option with AirPods: the housing is glued shut. In our battery article we compare all the routes — the outcome is almost always that a single replacement earbud is the cheapest reliable solution.
The solution: replace only the left earbud
Your right earbud and case are still fine, so replace only the left one. At Earbuds Restore you can buy a single left AirPod for every generation (AirPods 1 through 4, Pro 1 through 3) in five tested conditions. Left earbuds for AirPods 1 and 2 start at €33.80, AirPods 3 at €38.80, AirPods 4 at €52.80 and the Pro models from €52.80 (Pro 1) up to €92.80 (Pro 3). Like New comes with a 12-month warranty, refurbished conditions with 6 months.
Ordering works like this: determine your generation via the model number on your right earbud (model number guide), choose your condition, and pair the new earbud with your existing set on arrival using the pairing guide. Orders placed on business days before 4:00 PM are usually shipped the same day; delivery takes 1-2 business days.
Frequently asked questions
How do I see whether my left AirPod is charging?
Place the earbud in the case and open the lid next to your iPhone: the battery percentage for each earbud appears on screen. If you don't see the left earbud or the percentage doesn't move, it isn't making contact or isn't charging. On an Android phone, check this via an AirPods battery app or by testing the earbud after an hour of charging.
Why does one AirPod charge while the other doesn't?
Usually it's a contact problem: dirt on the charging contacts at the bottom of the earbud or in the bottom of the case slot prevents the earbud from getting power. Other causes are an earbud that doesn't quite click into place, a software glitch that a reset clears, or — with older sets — a worn battery in that one earbud.
Can the battery of a single AirPod be replaced?
Practically speaking, no. AirPods are glued shut and the battery is fixed inside the housing; a battery swap is more expensive and riskier than replacing the earbud. That's why a single replacement earbud of the same generation is the usual solution. We compare all options and costs in our article on battery replacement.
What does a single left AirPod cost?
At Earbuds Restore, single left earbuds for AirPods 1 and 2 start at €33.80 in Limited condition. AirPods 3 starts at €38.80, AirPods 4 at €52.80, AirPods Pro 2 at €71.80 and AirPods Pro 3 at €92.80. Every condition is tested; Like New comes with a 12-month warranty, refurbished conditions with 6 months.
Shouldn't I just replace the whole case or set?
Not if only the left earbud is the problem. If neither earbud charges, the problem is in the case — then check our article on a charging case that won't charge first. If only the left one won't charge, a single left earbud is all you need and you keep your own case and right earbud.
