So you've got an AirTag. Great little gadget, isn't it? Until that day you suddenly realize you haven't checked its battery in six months and now you're sweating bullets wondering if it'll die while your keys are lost in the couch cushions. Happened to me last Tuesday. Let's fix that.
Why Bother Checking Your AirTag Battery?
AirTags don't scream when their battery's dying. No push notifications, no flashing lights – nothing. I learned this the hard way when mine died during a road trip and my luggage tracker went dark. You only notice when it's too late. Since these things last about a year, it's easy to forget. But when the battery dies, so does your item tracking. Kinda defeats the purpose.
What Actually Drains the Battery?
It's not just time. Three things chew through your AirTag battery:
- Movement tracking: The more your tagged item moves, the more it pings nearby iPhones
- Precision Finding: Those fancy AR arrows? They use extra juice
- Temperature extremes: Left in a freezing car or hot garage? Battery drains faster
My gym bag AirTag lasts 8 months because it sits still most days. My dog's collar AirTag? Dead by month 10 from constant motion. Go figure.
The Only Real Way: Using Find My App
Let's cut to the chase. Apple gives you one official method for checking your AirTag battery status:
Step-by-Step: Check Battery in Find My
| Step | What You See | Pro Tip |
|---|---|---|
| 1. Open Find My app | Your Apple devices map | Works on iPhone/iPad/Mac - no Android |
| 2. Tap Items tab | List of your AirTags | Swipe left to rename if you haven't |
| 3. Select your AirTag | Location map and options | If it's offline, battery may already be dead |
| 4. Look under the AirTag name | Battery icon with status:
|
No percentage shown - Apple keeps it vague |
Weird thing? The battery icon won't even appear until it drops below 100%. Apple assumes you're fine until you're not. Helpful.
⚠️ Can't see the battery status? Try these fixes:
- Bring AirTag within Bluetooth range
- Restart your iPhone
- Remove/reinsert battery (more on this later)
What About Physical Indicators? (Spoiler: None)
Wish there was a LED indicator? Me too. Unlike Tile trackers, AirTags have:
- No blinking lights for low battery
- No audible alerts when dying
- No way to check without an Apple device
Kinda frustrating when you're trying to check AirTag battery life quickly. But there's one workaround...
The "Remove Battery" Hack
If your Find My app isn't showing status, pop open the AirTag:
- Press and twist the stainless steel back
- Remove the CR2032 battery
- Wait 10 seconds
- Reinsert battery until it chimes
This forces a refresh next time it connects. Works about 70% of the time in my tests. Still clunky though.
Battery Life Expectancy: Real-World Data
Apple claims "over a year." From my four AirTags and reader reports, here's reality:
| Usage Scenario | Avg. Battery Life | Factors That Kill It Faster |
|---|---|---|
| Keys/Wallet (minimal movement) | 12-14 months | Cold environments (winter coats) |
| Pet Collar/Bag (frequent movement) | 9-11 months | Precision Finding usage |
| High-Traffic Area (car, office) | 8-10 months | Temperature fluctuations |
My record? 15 months on keys rarely used during lockdown. My worst? 7 months on a dog collar in Arizona heat. Location matters.
When to Panic: Low Battery Warnings Explained
Finally, you see the ominous yellow icon. What now?
| Battery Status | What It Means | Time Left (Approx.) | Action Required |
|---|---|---|---|
| 🟢 Full | Everything's fine | 6+ months | Check again in 3 months |
| 🟡 Low | Battery at 10-20% | 2-4 weeks | Buy replacement batteries |
| 🔴 Replace Now | Critical low (under 10%) | Days to a week | Replace immediately |
⚠️ Warning: Once it hits red, the AirTag may disconnect unexpectedly. Lost my bike lock tag this way.
Choosing the Right Battery: CR2032 Showdown
Not all button batteries are equal. Here's what matters:
Battery Brand Comparison
| Brand | Price per Battery | Avg. Lifespan | Notes |
|---|---|---|---|
| Panasonic | $1.50-$2 | 12+ months | Original equipment, most reliable |
| Duracell | $1.75-$2.25 | 11-12 months | Widely available, consistent |
| Energizer | $1.25-$1.75 | 10-11 months | Good value, slightly shorter life |
| Generic (Amazon) | $0.50-$1 | 6-9 months | Risk of early failure - not worth it |
Personal take? Panasonic costs more but lasts longer. The $1 savings on generics? False economy when your luggage goes AWOL.
Lithium vs. Alkaline: Critical Difference
Must-use lithium batteries (CR2032). Why?
- Higher voltage stability
- Better performance in cold
- Longer shelf life
Alkaline batteries (like LR2032) might physically fit but won't work properly. Don't be that person.
Replacement Walkthrough: Avoid These Mistakes
Changed hundreds of these. Follow these steps:
- Press down on polished metal back
- Rotate counterclockwise until it stops
- Lift off back cover and battery
- Insert new CR2032 battery (+) side UP
- Align cover tabs and rotate clockwise
- Listen for confirmation chime
Common screw-ups I've seen:
- Inserting battery upside down (won't work)
- Forcing the cover (strip the threads)
- Using coin cells with lower mAh rating
🛠️ Pro Tip: Put a tiny dot of nail polish on the cover seam. If it rubs off, someone tampered with your AirTag.
Troubleshooting Battery Issues
Sometimes things go sideways. Common problems:
"Find My Not Showing Battery Status" Fixes
| Symptom | Likely Cause | Solution |
|---|---|---|
| No battery icon visible | iOS bug or poor connection | Restart iPhone → reopen Find My |
| Status stuck on "Full" | Outdated iOS version | Update to latest iOS |
| Intermittent disappearing | Weak Bluetooth signal | Bring AirTag closer to phone |
| Never shows battery status | Counterfeit AirTag | Verify serial number with Apple |
Had one stubborn AirTag that refused to show battery status for weeks. Solution? Reset it by removing battery five times consecutively. Painful, but worked.
Battery Life Hacks: Make It Last Longer
Want to stretch that battery? Try these:
- Disable Precision Finding: Only enable when actively searching (Settings → Privacy → Location Services → Find My)
- Reduce Movement Updates: For stationary items (like safes), reset location in Find My app monthly
- Store Spares Properly: Keep batteries in cool, dry place (not fridge!)
- Buy Fresh Batteries: Check expiration date - old stock loses charge
My controversial take? Precision Finding should auto-disable after 10 minutes. That feature drains 20% faster in my tests.
AirTag Battery FAQ
How much does an AirTag battery cost?
CR2032 batteries cost $1.50-$3 each. Buy multipacks for better value. Avoid dollar store batteries - false economy.
Can I recharge an AirTag battery?
Nope. The CR2032 is disposable. Rechargeable versions (like LIR2032) exist but aren't recommended due to lower voltage.
Why does my new AirTag show low battery?
Either: 1) Faulty battery (rare), 2) It's been sitting on a shelf for months, or 3) Counterfeit product. Check serial number with Apple.
Do AirTags work with rechargeable batteries?
Technically yes, but not advised. Rechargeable CR2032s have lower voltage (3.0V vs 3.3V) and may cause connectivity issues.
How to check AirTag battery without iPhone?
You can't. Requires Apple device with Find My app. Android users can't check battery status at all - major limitation.
Will I get notified when battery is low?
Only if you have iOS 15 or later. Notifications are inconsistent though - manually checking is more reliable.
Can I use a CR2025 battery instead?
Not recommended. Thinner (2.5mm vs 3.2mm) may cause contact issues. Stick with CR2032.
The Uncomfortable Truth About Battery Checks
Here's my beef with checking AirTag battery levels: Apple makes it too passive. Why no battery percentage? Why no customizable alerts? Why can't I see all battery levels at once?
Compared to my SmartTag+, the AirTag battery experience feels half-baked. But it's still the best tracker for iPhone users. Just set calendar reminders to check batteries every 3 months. Trust me.
Final thought? Knowing how to check AirTag battery properly saves you that frantic moment when you can't find your backpack and wonder..."Is it lost or just dead?"
