AirTag 2 is the better tracker for iPhone users. Its U2 chip extends Precision Finding up to 50% farther than the original, and the Find My network spans over a billion devices. SmartTag 2 is the better tracker for Samsung Galaxy owners, offering AR-guided finding, 700-day battery life, and free location history. Both cost $29. Your phone decides this one.
Apple released the AirTag 2 in January 2026 with a U2 UWB chip, a louder speaker, and Apple Watch Precision Finding. Samsung’s SmartTag 2 has been out since late 2023 — older hardware, yes, but it still holds strong advantages in battery life comparison chart, form factor, and smart home integration.
The two trackers behave very differently across airports, parking garages, and the house. Here’s what actually matters when you’re choosing between them.
- AirTag 2’s Find My network spans over a billion Apple devices; SmartTag 2’s SmartThings Find has 200 million Samsung devices — a coverage gap that matters most in rural areas and international travel.
- AirTag 2 Precision Finding extends up to 50% farther than the original with the U2 chip; SmartTag 2’s AR Find depends on Galaxy UWB support and local conditions.
- SmartTag 2 wins on battery life by a wide margin: up to 700 days in power-saving mode versus roughly 365 days for AirTag 2, both on the same CR2032 coin cell.
- SmartTag 2 includes a built-in keyring hole and doubles as a SmartThings remote for home automation; AirTag 2 requires a separate holder and has no smart home integration.
- Both cost $29-30 and have no subscription — the choice is entirely about your phone: iPhone means AirTag 2 wins, Samsung Galaxy means SmartTag 2 wins.
AirTag 2 vs SmartTag 2: Quick Specs Comparison
The split is really about phones, not hardware. According to Apple’s AirTag overview, Find My can draw on more than a billion Apple devices. Samsung’s SmartTag2 announcement states that the tag is IP67 rated and can run up to 500 days, but offline finding is limited to Samsung Galaxy phones. So your existing phone, not the spec sheet, picks the winner here.

Does Your Phone Pick Your Tracker?
This is the only question that matters for most buyers. AirTag 2 requires an iPhone 11 or later running iOS 14.5+, and it doesn’t work on Android at all, except for a basic NFC tap in Lost Mode that shows the owner’s contact info. No setup, no tracking, no Precision Finding on Android. Period.
SmartTag 2 requires a Samsung Galaxy phone running Android 11 or higher with the SmartThings app. Full UWB tracking (including the AR Find camera overlay) needs a Galaxy device with a UWB chip: the S21+ and above, plus their Ultra variants. Non-Samsung Android phones can’t set up or use the SmartTag 2 at all.
Mixed household? Neither tracker covers everyone. If you’ve got iPhones and Pixels under the same roof, check our AirTag alternatives guide for cross-platform options like Chipolo Pop and Pebblebee Clip 5.
AirTag 2’s Precision Finding Has a Longer Range
Both trackers use UWB for directional finding, but AirTag 2 works from farther away. The U2 chip (same silicon as the iPhone 17 and Apple Watch Ultra 3) extends Precision Finding to a longer range. Apple’s January 2026 announcement states that the U2 chip extends Precision Finding range up to 50% farther than the original. That extra reach is what shows up when you are searching a large open space.
In a parking garage, that extra range can help your phone surface guidance sooner. With the U2 chip’s longer reach, AirTag 2 is better suited to large concrete structures than the original AirTag.
SmartTag 2 uses an AR Find mode that overlays a directional arrow onto your Samsung phone’s live camera feed. Visually, it’s more intuitive than Apple’s simple arrow because you literally see where to walk, but its reliability still depends on UWB support, walls, and obstacles.
For finding keys in your couch cushions, both work equally well. For larger spaces like a hotel lobby, a parking lot, or an airport terminal, AirTag 2 pulls ahead. Our AirTag accuracy guide covers how UWB ranging works in more detail.
Speaker Volume
Apple says AirTag 2 is 50% louder than the original. Samsung’s SmartTag 2 speaker is also designed for audible close-range finding, but the exact experience depends on where the tag is buried and how noisy the space is.
Apple Watch Precision Finding
This is new for AirTag 2 and something SmartTag 2 simply can’t match. If you own an Apple Watch Series 9, Ultra 2, or newer, you can run Precision Finding directly from your wrist — left your phone in the car? You can still locate your AirTag from your watch.
It’s a convenience feature for searches where your phone isn’t in hand. For SmartTag 2 users, there’s no Galaxy Watch equivalent; you need your phone. Samsung’s Galaxy SmartTag product page lists the official specs.
Does Network Size Decide Long-Range Tracking?
AirTag’s network is much larger, and that gap shows up when your item travels far from you.
Apple’s Find My network runs on over a billion active Apple devices. Every iPhone, iPad, Mac, and Apple Watch running iOS 14.5+ acts as a silent relay, picking up a nearby AirTag’s Bluetooth ping and forwarding the encrypted location to you. Leave an AirTag in a taxi in Tokyo or a cafe in Berlin, and the odds of a nearby Apple relay are high.
Samsung’s SmartThings Find relies exclusively on Samsung Galaxy devices. Notebookcheck reported that SmartThings Find passed 200 million connected devices — solid coverage in South Korea, parts of Germany, and major US cities.
But in rural areas or countries where Samsung’s market share is thinner, updates slow down. If your bag goes missing at a small regional airport, the SmartTag 2 may have fewer relay opportunities.
One clear SmartTag 2 advantage: free 30-day location history. You can trace exactly where your tracker has been over the past month, while AirTag only shows you where your item is right now, not where it’s been.
That difference matters if you’re tracking a vehicle or trying to figure out where you lost something days ago. For more on why Apple made this tradeoff, see our does AirTag have GPS explainer, and for a broader look at how Apple Find My and Google Find Hub compare as platforms, see our Find My vs Find Hub ecosystem comparison.
SmartTag 2’s Battery Lasts Nearly Twice as Long
SmartTag 2 wins this round by a wide margin. In standard mode, it runs for up to 500 days. Turn on power-saving mode in the SmartThings app, and Samsung claims up to 700 days — close to two years on a single CR2032 coin cell.
AirTag 2 lasts about one year — same battery, same CR2032, same user-replaceable design. For items you check on regularly (keys, a wallet), one year is fine; for things you toss in a storage unit and forget about, the SmartTag 2’s extra runtime matters.
Both batteries cost under $2 to replace, and neither tracker has a rechargeable option. If you’re curious about the replacement process, it’s nearly identical for both: twist the back, swap the coin cell, done.
Apple rates the AirTag 2 at roughly a year on a single coin cell. A 10-pack of CR2032s runs about $6, so battery cost is essentially a rounding error over the life of either tracker.
Design and Extra Features: More Different Than You’d Expect
AirTag 2 is a tracker. SmartTag 2 is a tracker that also does other things.
Form Factor
AirTag 2 is a flat 31.9mm disc with a polished steel back, with no keyring hole — you’ll need a separate holder, and Apple’s official ones start at $29, essentially doubling the cost. Third-party options run $5–$15. SmartTag 2 has a built-in keyring hole reinforced with a metal insert; clip it to your keys and you’re done, no extra purchase.
Smart Home and NFC
SmartTag 2 is also a SmartThings remote. Long-press the button to trigger automations: turn off lights, arm your security system, run any SmartThings routine you’ve set up.
You can also embed contact information via NFC, so anyone with any NFC-capable phone (including iPhones) can tap it to see your phone number or email. AirTag 2’s NFC only works in Lost Mode — no smart home features at all.
Anti-Stalking Protections
According to Apple and Google’s joint press release, both comply with the cross-industry DULT (Detecting Unwanted Location Trackers) standard that protects over 3 billion smartphone users. AirTag 2 alerts iPhone users if an unknown AirTag has been traveling with them, and Android users get alerts through the cross-platform tracker detection framework. SmartTag 2 sends similar alerts to Samsung Galaxy users. Neither system is foolproof, but both meet the spec.
Pricing Is Nearly Identical
| Package | AirTag 2 | SmartTag 2 |
|---|---|---|
| 1-pack | $29 on Amazon | about $30 on Amazon |
| 4-pack | $99 on Amazon | about $100 on Amazon |
| Subscription | None | None |
Price isn’t a differentiator here. Both are $29–$30 for one, roughly $99–$100 for four, and neither charges a monthly subscription. The hidden cost with AirTag 2 is the holder — budget an extra $10–$35 per tracker for a keyring case if you need one, while SmartTag 2 attaches to things out of the box.

Frequently Asked Questions
Can Samsung SmartTag 2 work with an iPhone?
No. SmartTag 2 requires a Samsung Galaxy phone with the SmartThings app. The only cross-device interaction is NFC: anyone with an NFC-capable phone, including iPhones, can tap the tag to see embedded contact info. But you can’t set up, track, or receive alerts on an iPhone.
Does SmartTag 2 work with Pixel or other Android phones?
No. It’s Samsung-exclusive. Google Pixel, OnePlus, Motorola, and all other non-Samsung Android phones can’t set up or use the SmartTag 2. For non-Samsung Android users, Tile Pro and Chipolo Pop are the strongest alternatives.
What changed from the original AirTag to AirTag 2?
Three things: the U2 UWB chip extends Precision Finding range up to 50% farther than the original, the speaker is 50% louder, and Apple Watch Series 9 or Ultra 2 can now run Precision Finding without your iPhone. Same $29 price, same CR2032 battery, same IP67 rating, same disc design. Apple’s official AirTag 2 spec page has the full details.
Which tracker has better battery life?
SmartTag 2. Not close. Standard mode lasts 500 days, power-saving mode stretches to 700 days. AirTag 2 lasts about a year. Both use the same CR2032 coin cell that costs under $2 to replace.
Is AirTag 2 or SmartTag 2 better for tracking luggage internationally?
AirTag 2, and it’s not particularly close. The Find My network spans over a billion devices across 180+ countries, which creates more relay opportunities in major airports. SmartThings Find coverage is strong in South Korea and urban areas but thins out in countries where Samsung’s market share is lower. For travel-specific recommendations, our luggage tracker guides cover the best options.
Do either of these trackers need a subscription?
Neither one. AirTag 2 works with the free Find My app. SmartTag 2 works with the free SmartThings app, including 30-day location history at no charge. Worth noting: Tile charges $2.99/month for the same location history that SmartTag 2 gives away free.
Can I use AirTag 2 or SmartTag 2 to track a car?
You can hide either one in a vehicle, but don’t expect real-time GPS tracking. These are Bluetooth trackers that update location only when another device in the network passes within range. Busy cities and rural areas can behave very differently. If you need live tracking on an independent cellular schedule, a dedicated GPS tracker like Bouncie is the better fit.
