7. Buy in Multipacks for Convenience
Since AirTag batteries typically last about a year, buying a multipack can be cost-effective and ensures you always have a spare when needed.
8. Properly Dispose of Old Batteries
Dead lithium batteries should be recycled properly instead of being thrown away in regular trash, as they can be harmful to the environment. Many electronic stores or recycling centers accept them.
Extending AirTag Battery Life
If you want to maximize your AirTag’s battery life, here are some tips:
- Minimize Sound Alerts: Avoid using Play Sound unnecessarily.
- Limit Precision Finding Use: Use Precision Finding only when necessary.
- Keep It in a Stable Location: If your AirTag constantly moves, it may send location updates more frequently, using more battery power.
- Store in Optimal Temperatures: Avoid exposing AirTags to extreme heat or cold, which can degrade battery life.
- Turn Off Unused AirTags: If you do not need to track an item for an extended period, consider temporarily removing the battery.
- Use Battery Monitoring Apps: Some third-party apps may help track your battery performance more accurately.
What Happens When an AirTag Battery Dies?
When an AirTag’s battery runs out, it will no longer send location updates or play sound alerts. However, your AirTag will remain associated with your Apple ID, and once a new battery is inserted, it will resume normal function without requiring re-pairing.
1. AirTag Stops Tracking
Once the battery dies, your AirTag will no longer communicate with your Apple devices, meaning you won’t be able to see its last known location or track it in real-time.
2. Find My App Shows “Battery Dead” Warning
Before the battery fully drains, Apple’s Find My app notifies users with a low-battery alert. If ignored, the AirTag eventually disappears from the active tracking list.
3. No Sound Alerts
A functional AirTag can play a sound when you search for it, but after the battery dies, it loses this capability, making it harder to locate.
4. Precision Finding Becomes Unavailable
If you use a compatible iPhone with Precision Finding, this feature won’t work once the AirTag runs out of power, as the device stops sending out its Bluetooth signal.
5. AirTag Won’t Be Detected by Other Apple Devices
The AirTag relies on Apple’s Find My Network, where nearby Apple devices help track lost AirTags. With a dead battery, it stops emitting signals, making it undetectable.
6. You Can Still Replace the Battery
AirTags uses a standard CR2032 coin cell battery, which is user-replaceable. You simply twist open the back cover, swap the battery, and the AirTag will work again.
7. Lost Mode Becomes Ineffective
If your AirTag is in Lost Mode, it won’t be able to update its location or notify someone who finds it because it cannot send any signals without power.
