Your Nothing Ear (3) won't charge. The case LED stays dark when you plug it in, or one earbud sits at 5% while the other shows 80%, or the case itself refuses to charge over Qi. These issues are almost always fixable without a warranty claim, and you have plenty to try before giving up.
Start with the obvious one. Pull both earbuds out of the case and inspect the gold charging contacts on the stems and the spring-loaded pins inside the case wells. If you see any lint, earwax, or residue, that's your main suspect. A quick dry wipe fixes more charging problems than anything else.
Check the USB-C Port for Debris
The most common hidden cause is pocket lint compacted inside the USB-C port on the back of the case. Shine a flashlight into the port. You'll almost always see a tight plug of fluff at the bottom. Use a wooden toothpick or plastic SIM ejector to gently pick it out. Don't use anything metal the port pins are delicate and a short will kill the charging circuit. This single step clears the majority of "won't charge over USB-C" cases in under a minute.
Clean the Earbud Contacts and Case Pins
Earwax builds up on the gold contacts at the bottom of each stem faster than most people realize. The same goes for the three pins inside each earbud well inside the case. When those metal surfaces can't make solid contact, charging fails silently, the case LED might flash as if everything's normal but the buds get nothing.
Take a dry, lint-free microfiber cloth and gently rub each contact. For stubborn gunk, a cotton swab slightly dampened with isopropyl alcohol (90% or higher) works great, just don't saturate anything. Let everything air dry for a minute or two, then put the buds back in the case and close the lid. Both buds should report similar percentages within a few minutes.
Swap the USB‑C Cable and Charger
The Nothing Ear (3) case accepts USB-C input at 5W standard. Cables go bad over time, and a cable that charged fine last week might not deliver enough power today. Use a known-good cable, preferably the one that came with the case or any certified USB-C cable. If the case starts charging with a different cable, toss the old one.
When testing, plug the cable directly into a wall adapter that supplies at least 5W. Avoid computer USB ports, they often provide inconsistent power and can leave the case stuck at the same percentage for hours.
Position the Case Correctly on a Qi Charger
Wireless charging for the Nothing Ear (3) case works with any standard Qi pad, but alignment matters. The charging coil sits toward the bottom half of the case. If you drop the case on the pad and the small LED on the front doesn't light up within a couple seconds, move it around until it does. The case front has a small circular indicator that glows briefly when charging starts.
Take any thick third-party case off the Nothing case first. Some silicone skins or hard shells push the internal coil too far from the charger to couple properly. With the bare case placed flat on a clean Qi pad, you should see the LED flash. If nothing happens after a few seconds, try a different Qi charger or any USB-C cable instead.
Check the Case Battery Level
Sometimes the earbuds aren't charging because the case itself is completely drained. Put the case on a charger (USB-C or Qi) for at least 15 minutes with the lid closed. Then open the lid near your phone and launch the Nothing X app. It should show both the case and earbud battery levels. If the case remained at the same percentage after 15 minutes plugged in, the internal case battery may have issues, and the buds inside won't charge until the case does.
Force a Factory Reset
If cleaning and cable swaps haven't worked, a full reset often clears firmware glitches. Open the case lid. Press and hold the button on the back of the case for exactly 10 seconds. The LED on the front will flash red, indicating the reset has taken effect. Release the button. The Nothing Ear (3) will be removed from all paired devices. Re-pair them using the Nothing X app: open the app, tap Add new device, and follow the prompts with the case lid open. A stale charging detection state can block power delivery, and the reset wipes that clean.
Charge One Bud Solo
If only one earbud charges and the other stays at zero, the silent bud might be stuck in a software loop. Remove the working bud from the case and leave the dead bud alone in the case with the lid closed for 15 20 minutes. When it's the only bud the case communicates with, the in-ear detection and firmware often recover. Put the working bud back in afterward and check both levels in the Nothing X app. If the previously dead bud now shows a matching percentage, you're good. If it's still at zero, that specific earbud likely has a hardware problem.
Update Firmware via the Nothing X App
Nothing pushes firmware updates for the Ear (3) through the Nothing X app. The update happens automatically when the earbuds are in the case, the case is closed, and it's connected to a phone with the app running in the background. To force a check, open the Nothing X app while the buds are in the case and the case lid is closed. Tap the gear icon next to your device name, scroll to Firmware update. The app will scan for available updates. If you see one, install it. Older firmware versions have had known charging communication bugs, and updating often fixes them.
Try a Different Wall Adapter or Qi Pad
If you've swapped cables, cleaned ports, and reset the device, test the case on a completely different charging setup. Borrow a friend's USB-C charger or Qi pad. If the case charges fine there, your original charger is the problem. If it still won't take a charge, the case charging circuit may have failed. At that point, contact Nothing support through the app for a replacement, especially if you're within the 1-year warranty. The case is replaceable separately from the buds.
