Samsung just shrank its tracker, stretched the battery, and – plot twist – let iPhone owners into the club. The Galaxy SmartTag3 is about 35% smaller by volume and 33% lighter than SmartTag2, rated for up to 790 days of battery in Power Saving Mode, and for the first time it works with iOS through SmartThings Find. US price: $29.99 for one or $99.99 for a four-pack, landing in the US by early November 2026 in White and Black.
Smaller puck, no built-in hole
SmartTag3 ditches the old key-fob shape for a rounded squircle puck with an aluminum-decorated button. Samsung’s official renders show no built-in lanyard loop, so plan on a case: Samsung is launching a Silicone Case with a keyring and a Loop Case, both sold separately (accessory pricing was not in the launch materials). It keeps an IP67 water and dust rating – fine for rain and a dunk, not a beach day.
Battery that outlasts your gym membership
Samsung rates SmartTag3 for up to 550 days under standard use and up to 790 days in Power Saving Mode, tested with the in-box CR2032 coin cell. Power Saving Mode trims extras like Compass View and ringtone settings and keeps basic Bluetooth LE finding. Your mileage will vary with how often you ping it.
Yes, it works with iPhone – with an asterisk
This is the first SmartTag with cross-OS support. Through SmartThings Find, iPhone users can check and share a tag’s location and use Search Nearby – handy when your iPhone-toting partner borrows the tagged suitcase. Important fine print: this is Samsung’s network, not Apple Find My, and Compass View, Ring Phone, and Left Behind Alert are not available on iOS. Galaxy owners still get the full buffet.
Compass View now reaches about 200 feet
On supported Galaxy phones, Bluetooth 6.0 Channel Sounding lets Compass View give distance and direction from up to 60 meters (about 197 feet, line of sight) – roughly three times the previous generation. Get closer and ultra-wideband takes over for precise pointing. The catch: Channel Sounding currently works only on the Galaxy S26 Ultra, S26 Plus, Z Fold8, and Z Fold8 Ultra; other UWB-equipped Galaxy phones on Android 12+ still get Compass View, just without the Channel Sounding reach.
Out of Bluetooth range, the Galaxy Find Network – more than 900 million participating Galaxy devices – keeps updating the tag’s location, and Samsung says those updates now arrive faster after disconnection.
Alerts that come to you
- Place Notification (trial feature) – draw an area and get pinged when a tagged pet, bike, or bag leaves or enters it

- Movement Detection Alert – a heads-up when a disconnected tag is detected moving
- Left Behind Alert – nags you when your phone loses the tag (Galaxy only)
- NFC Lost Mode – a finder taps the tag to see your contact info or message
- SmartThings button – press the tag to fire a smart home routine
Price and availability
SmartTag3 launches in Korea on October 7, then hits the US by early November 2026 at $29.99 (one) or $99.99 (four-pack) in White or Black. That is the same price as SmartTag2. Samsung has not posted a US product page or exact on-sale date yet, and cases are extra.
Caveats before you tag everything you own
The best tricks (long-range Compass View, Left Behind Alert, Ring Phone) are still Galaxy-first, and the 60 m figure needs one of four 2026 Galaxy flagships plus clear line of sight. iPhone support is real but basic. Battery numbers are Samsung lab estimates. Coin-cell trackers on pet collars can detach – Samsung itself warns about swallowing hazards, so check the case regularly.
