How Long Do AirTags Last? Apple’s Official Claim vs. Real-World Use
Apple’s AirTags have become essential for tracking keys, bags, and more. But before relying on them, it’s crucial to understand their battery life.
Apple’s Official Battery Life Estimate
Apple states that AirTags last over one year on a standard CR2032 coin-cell battery, based on average usage. This estimate assumes you trigger the speaker or use Precision Finding a few times daily.
Real-World AirTag Battery Performance
In practice, AirTag battery life varies. Users report 8–14 months, depending on factors like:
- Frequency of location updates.
- Environmental conditions (extreme temperatures drain batteries faster).
- How often do you play sounds or use precision finding?
Factors That Impact AirTag Battery Life
1. Usage Frequency
AirTags in high-traffic areas (e.g., a lost backpack) update locations more often, consuming more battery.
2. Environmental Conditions
Cold weather can temporarily reduce battery efficiency, while heat may cause long-term damage.
3. Bluetooth and Precision Finding
Frequent use of Bluetooth features like precision finding or playing sounds accelerates battery drain.
4. Firmware Updates
AirTags receive occasional firmware updates, which may optimize battery usage over time.
How to Replace an AirTag Battery?
When your AirTag battery dies, replacing it is simple:
Step-by-Step Replacement Guide
- Twist the Backplate: Press and rotate the stainless steel cover counterclockwise.
- Remove the Old Battery: Use a coin or fingernail to pop out the CR2032 battery.
- Insert a New Battery: Ensure the “+” side faces up.
- Reattach the cover: align the tabs and twist clockwise until it clicks.
Pro Tip: Use lithium-based CR2032 batteries (e.g., Duracell, Panasonic) for optimal performance.
Tips to Extend Your AirTag’s Battery Life
1. Minimize Unnecessary Sound Alerts
Limit using the “Play Sound” feature unless searching for a lost item.
2. Avoid Extreme Temperatures
Store AirTags in moderate climates to preserve battery health.
3. Update Firmware Regularly
Keep your AirTag firmware current via the Find My app for efficiency improvements.
4. Use Power-Saving Mode
If not in use for extended periods, remove the battery temporarily.
AirTag Battery Life vs. Competitors
Compared to rivals like Tile and Samsung Galaxy SmartTag+, AirTags generally last longer:
- Tile Pro: 1 year (replaceable battery).
- Samsung Galaxy SmartTag+: 5–6 months (non-replaceable battery).
AirTags’ user-replaceable battery and efficient Apple ecosystem integration give them an edge.
FAQs About AirTag Battery Life
Q: Will my iPhone notify me when the AirTag battery is low?
A: Yes! The Find My app sends a notification when the battery drops below 10%.
Q: Are AirTags rechargeable?
A: No—Apple designed them with replaceable CR2032 batteries for convenience.
Q: Can I use any CR2032 battery?
A: Stick to name-brand lithium batteries for reliability. Avoid cheap alternatives.
Final Thoughts
AirTags typically last 8–14 months, depending on usage. With easy battery replacement and smart habits, you can maximize their lifespan. Whether tracking luggage or pets, understanding these factors ensures your AirTag stays powered when you need it most.
