How to Keep Your AirTag Working Reliably: Essential Maintenance Tips

An AirTag is designed to be durable and low-maintenance, but like any small electronic device, it benefits from basic care. Understanding what keeps it functioning well—and what can wear it down—helps you get reliable tracking for as long as you need it. 🏷️

What You're Actually Maintaining

Your AirTag contains a replaceable battery, a small circuit board, and a speaker. The battery is the only component most people ever need to replace. The rest of the device is sealed and not user-serviceable, so your maintenance job focuses on protecting it from damage and keeping the battery fresh.

Battery Care and Replacement

The battery is your AirTag's lifespan bottleneck. A standard CR2032 coin battery typically powers an AirTag for a year or so under normal use, though the actual duration depends on how often your device searches for it and how many times it connects to nearby Apple devices.

To replace the battery:

  • Locate the polished stainless steel back
  • Press down and rotate counterclockwise until it comes loose
  • Remove the old battery and slide in a fresh CR2032 (available at most pharmacies and hardware stores)
  • Snap the back into place and ensure it clicks

Your AirTag will notify you in the Find My app when the battery is running low, giving you time to plan a replacement before it dies completely.

Physical Protection Strategies

AirTags are water-resistant (rated IP67, meaning they can handle splashes and brief immersion), but that doesn't mean they're indestructible.

Common wear scenarios:

SituationRisk LevelWhat Helps
Loose in a pocket or bagModerateUse a case or pouch
Attached to a keychainLowMinimal; polished back can scratch cosmetically
Outdoor attachment (keys, pet collar)Moderate to highCase protects against dirt, UV, and impact
Near magnets (home security, industrial settings)Low ongoingMagnets don't disable the chip, but may affect physical casing over time

If your AirTag is exposed to extreme temperatures, intense sunlight, saltwater, or heavy impacts, consider a protective case. Many third-party cases are available, though they typically add bulk.

Storage and Environmental Care

If you're storing an AirTag for extended periods:

  • Remove or replace the battery if you won't use it for months (prevents slow drain)
  • Keep it in a cool, dry place away from direct sunlight
  • Avoid storing it compressed or under heavy objects

Occasional exposure to humidity, dust, and temperature swings is fine. AirTags are designed for everyday use in normal home and outdoor conditions.

Keeping Your Device Discoverable

Your AirTag's usefulness depends on staying paired with your Apple ID. Periodically check:

  • That it still appears in the Find My app
  • That you can locate it using the app's "Find" feature
  • That your device name and contact info are current (tap the info icon in Find My to update these)

If an AirTag stops appearing in Find My, forget it from your device and re-add it by scanning the setup code on the back.

When an AirTag Stops Working

Non-functional battery is by far the most common reason an AirTag stops responding. Replace it first.

Lost connection to Find My can sometimes be resolved by removing and re-adding the AirTag, or by restarting your iPhone.

Water damage or physical failure is rare but possible. If your AirTag survived a drop, heavy water exposure, or extreme temperature, and replacement didn't help, the device itself may be damaged. Apple does not repair individual AirTags—replacement would be your option.

The Bottom Line

Your role in AirTag maintenance is simple: watch the battery level, replace the battery when prompted, and give it reasonable physical protection based on how you use it. Beyond that, these devices ask very little of you. 📍
