How to Fix Apple AirTag Battery and Power Issues

On By In Wearables

Key Takeaways

  • Apple AirTags are powered by a small replaceable battery that usually lasts up to a year.
  • Common battery problems include sudden battery drain, pairing issues, or the AirTag not being detected at all.
  • Using incompatible batteries, extreme temperatures, or dirt inside the AirTag can cause power issues.
  • Replacing the battery correctly and using the right type can resolve most problems.
  • If the AirTag still won’t work after changing the battery, a reset or replacement may be needed.

Apple AirTags are designed to be low-maintenance, but they’re not immune to battery and power issues. If your AirTag suddenly stops working, doesn’t show up in the Find My app, or gives low battery warnings too soon, don’t worry — there are simple solutions to get it working again.

Why Your Apple AirTag Has Battery or Power Issues

  • The battery is completely drained or inserted incorrectly
  • You’re using a non-recommended battery (especially ones with a bitter coating)
  • The AirTag was exposed to moisture or dirt
  • There’s a temporary glitch or bug in the Find My system
  • The AirTag is in extreme cold or heat
  • The battery contact inside the AirTag is dirty or misaligned

Check for Low Battery Alerts

Apple sends a notification when your AirTag’s battery is low.

  1. Open the Find My app on your iPhone.
  2. Tap the Items tab.
  3. Select your AirTag.
  4. If the battery is low, you’ll see a “Low Battery” warning under the AirTag name.

If you see this message or your AirTag stops working, it’s time to replace the battery.

Replace the Battery (CR2032 Coin Cell)

AirTags use a CR2032 coin battery, which is easy to find. But some brands may not work.

  1. Hold your AirTag with the Apple logo facing down.
  2. Press down and twist the metal back counterclockwise until it pops off.
  3. Remove the old battery.
  4. Insert a new CR2032 battery with the + side facing up.
  5. You’ll hear a chime if it’s inserted correctly.
  6. Put the metal cover back on and twist clockwise to lock it in place.

Important: Avoid CR2032 batteries with a “bitter coating” (used to prevent swallowing). These can block the battery contacts and cause connection issues.

Make Sure the Battery Is Compatible

Not all CR2032 batteries are the same.

  • Choose brands like Energizer, Panasonic, or Duracell (non-coated).
  • Stay away from bitterant-coated versions, which are often labeled as “child-safe.”
  • Always check packaging for “AirTag compatible” or no bitter coating.

Clean the AirTag Battery Contacts

If the AirTag isn’t working even with a new battery, dirt or corrosion may be to blame.

  1. Remove the battery as shown above.
  2. Use a soft cotton swab or microfiber cloth to gently clean the metal contact points inside.
  3. If there’s visible corrosion, lightly wipe with isopropyl alcohol and let it dry completely.
  4. Reinsert the battery and check if it chimes.

Avoid Extreme Temperatures

AirTag batteries can drain faster or stop working in hot or freezing conditions.

  • Don’t leave your AirTag in direct sunlight or in a hot car.
  • Avoid using it in below-freezing weather for extended periods.
  • Let the AirTag return to room temperature before replacing the battery.

Reset the AirTag

If you’re sure the battery is fine but the AirTag still won’t work, try resetting it.

  1. Remove the battery.
  2. Wait 10 seconds, then reinsert it.
  3. When you hear the chime, remove the battery again.
  4. Repeat this 5 times (yes, five times total).
  5. On the fifth insert, the AirTag will reset and chime again.
  6. Now re-pair it with your iPhone through the Find My app.

Still Not Working? Try These

  • Restart your iPhone in case the problem is with the Find My app.
  • Update iOS to make sure you’re not dealing with a software bug.
  • Contact Apple Support if the AirTag still doesn’t respond — it may be defective.

Apple AirTags are simple devices, but even they can hit snags with power. Most battery issues can be fixed with a proper replacement, good cleaning, and using the right battery type. With just a few minutes of effort, you can bring your AirTag back to life and keep your belongings safe.

FAQ’s

1. How long should an AirTag battery last?

About 1 year under normal use. You’ll get a notification when it’s time to replace it.

2. What if my AirTag won’t chime after replacing the battery?

Make sure the + side of the battery is facing up and try a different battery brand (without a bitter coating).

3. Can I use rechargeable coin batteries in my AirTag?

It’s not recommended — AirTags are designed for single-use CR2032 batteries, and rechargeables may not fit or function properly.

4. Why did my new battery drain so quickly?

It could be a coated battery, poor brand, or the AirTag was in extreme heat or cold. Also check for background activity or a faulty unit.

5. Will a factory reset fix battery issues?

It can help if your AirTag is glitching, but it won’t fix a physically drained or damaged battery.
