AirTags are incredibly useful for keeping track of personal items like keys, bags, and even pets. These small, button-shaped devices from Apple use the Find My app on an iPhone to help locate lost belongings. AirTags do not need recharging but their batteries will need replacement after about a year.
AirTags use a CR2032 battery, which is small and user-replaceable. Apple states that the battery should last for over a year with normal usage. When the battery gets low, users will receive a notification on their iPhone, making it easy to know when it’s time to replace it.
When an AirTag’s battery dies, the tracking capabilities stop until the battery is replaced. To change the battery, simply press and twist the metal back of the AirTag. Once the new battery is in, the AirTag resumes its tracking functions immediately.
🧭 Can an AirTag Die?
Yes — an Apple AirTag can die, but not in the same way as most electronic devices. The AirTag itself doesn’t have a rechargeable battery or internal power source that permanently fails; instead, it runs on a replaceable coin-cell battery (CR2032). Once that battery runs out, the AirTag will stop working until you replace it.
🔋 1. How Long Does an AirTag Battery Last?
According to Apple and multiple independent tests, an AirTag’s battery typically lasts about one year with normal use (SimplyMac; MSN).
Battery life depends on:
- How often you use the Find My app to ping or locate the tag.
- How frequently the AirTag plays sounds.
- Environmental factors like temperature and humidity.
Some users report batteries lasting up to 14–16 months, while heavy use can reduce that to 8–10 months.
⚠️ 2. Signs Your AirTag Battery Is Dying
You’ll know your AirTag battery is running low when:
- You receive a “Low Battery” notification in the Find My app.
- The AirTag stops playing sound when prompted.
- The AirTag no longer updates its location in the app.
Once the battery is completely drained, the AirTag will “die” — meaning it won’t track, beep, or appear in Find My until you replace the battery.
🪙 3. How to Replace the AirTag Battery
Replacing the battery is simple and takes less than a minute:
- Press down on the stainless steel back cover and rotate it counterclockwise.
- Remove the old CR2032 coin-cell battery.
- Insert a new CR2032 battery (positive side up).
- Replace the cover and twist it clockwise until it clicks.
💡 Tip: Avoid CR2032 batteries with a bitter coating (used to deter children), as some coated versions can interfere with the AirTag’s contact points (MacObserver).
🧠 4. Can an AirTag Die Permanently?
Only in rare cases. An AirTag can “die permanently” if:
- It’s physically damaged (e.g., water ingress beyond its IP67 rating).
- The internal electronics fail due to impact or corrosion.
- The AirTag is lost and out of Bluetooth range for an extended time (it won’t function until found and reconnected).
Otherwise, replacing the battery revives it instantly.
🌱 5. How to Extend AirTag Battery Life
To maximize battery lifespan:
- Limit how often you make the AirTag play sounds.
- Avoid extreme temperatures.
- Keep firmware updated (Apple occasionally improves efficiency).
- Store unused AirTags with the battery removed if you won’t use them for months.
✅ Summary
| Question | Answer |
|---|---|
| Can an AirTag die? | Yes, when the battery runs out. |
| Is it permanent? | No — just replace the CR2032 battery. |
| Average lifespan? | About 1 year with typical use. |
| Replacement cost? | Around $1–$2 per battery. |
In short:
An AirTag doesn’t truly “die” — it just needs a new battery. With proper care and timely replacements, your AirTag can last for many years.
AirTag Lifespan: Separating Fact from Fiction
AirTags, Apple’s tiny tracking devices, offer a convenient way to locate lost belongings. But with their reliance on a small battery, questions arise about their lifespan and potential for failure. Let’s explore what happens when an AirTag’s battery dies and how you can extend its life.
What Happens When an AirTag’s Battery Dies?
The AirTag’s battery, a standard CR2032 coin cell, is designed to last about a year under typical usage. When it runs out of juice, the AirTag can no longer broadcast a Bluetooth signal, making it untraceable through the Find My network.
However, the AirTag itself doesn’t “die.” It simply becomes inactive. You can replace the battery to revive it and continue tracking your item.
Warning Signs and Replacement
Your iPhone will notify you when an AirTag’s battery is running low. You’ll also see a “Low Battery” message next to the AirTag in the Find My app. Replacing the battery is a simple process:
- Press down on the AirTag’s polished stainless steel battery cover and rotate counterclockwise until it stops.
- Remove the cover and the old battery.
- Insert a new CR2032 battery with the positive side facing up.
- Replace the cover and rotate it clockwise until it clicks into place.
Factors Affecting Battery Life
| Factor | Impact on Battery Life |
|---|---|
| Usage Frequency | More frequent tracking leads to faster battery drain. |
