Galaxy SmartTag3 vs. SmartTag2: The Biggest Changes Explained

Samsung’s Galaxy SmartTag3 brings three headline changes over the SmartTag2: a smaller, lighter body, a higher claimed battery life and support for iPhones. But cross-platform phone support doesn’t mean cross-platform tracking networks: the tag still works through Samsung’s SmartThings Find and Galaxy Find Network. 2614

What’s new compared with SmartTag2?

Smaller body, with attachment accessories sold separately

The SmartTag3 is about 35% smaller by volume and 33% lighter than the SmartTag2. Samsung has removed the built-in attachment loop, so the tag needs an accessory or another way to secure it to keys, bags or other belongings. The accessories highlighted at launch are a Silicone Case with a keyring and a Loop Case. 367

Longer claimed battery life

Samsung says the SmartTag3 can last up to 550 days under standard use, or up to 790 days in Power Saving Mode. For comparison, reporting lists the SmartTag2’s ratings as up to 500 days in normal use and 700 days in power-saving mode. These are maximum claims, not guaranteed runtimes; actual battery life depends on use. 5813

iPhone support, but not Apple Find My

For the first time in the SmartTag lineup, iPhone users can use SmartThings Find for core locating and sharing features. Some functions remain exclusive to Galaxy phones, according to reporting; the available information does not establish a complete list of which features are limited by phone or operating system. 2313

The distinction that matters is the network: SmartTag3 uses Samsung’s Galaxy Find Network, rather than joining Apple’s Find My or Google’s Find Hub. iPhone compatibility lets iPhone owners use Samsung’s app; it does not make the tracker part of Apple’s locating network. 1415

How its finding features work

Samsung describes longer-range finding and faster location updates through the Galaxy Find Network. Bluetooth 6.0 Channel Sounding supports Compass View, which provides distance and directional guidance at up to 60 meters, according to Samsung’s published information. Reporting also describes UWB for more precise nearby finding; one report says it is used within 20 meters. The sources do not fully specify which phone models support each method or the conditions required for those ranges. 21924

The SmartTag3 also adds or expands proactive alerts. Place Notification can alert users when a tag enters or leaves a defined area, while Location History lets users review where a tag has been. The available information does not clearly establish whether these features work identically across iPhone and Galaxy devices. 41221

Launch dates and US price

Samsung announced the SmartTag3 on September 30, 2026. Its German announcement says sales start in Korea on October 7, with Germany following in early 2027. Reporting puts US availability in early November; other launch dates may vary by market. 281823

The reported US price is $29.99 for one tag or $99.99 for a four-pack. Pricing for the cases and other accessories is not established in the available reporting. 818

How it compares with AirTag and Google’s tracker ecosystem

The clearest competitive difference is that SmartTag3 now works with iPhones through SmartThings Find. That makes it a possible option for households using both Galaxy phones and iPhones, but it is not equivalent to a tracker that participates in Apple’s Find My network. It also does not join Google Find Hub. 21415

The available sources do not provide enough consistent, like-for-like information to compare SmartTag3’s full specifications with the second-generation AirTag or a Google Pixel Tag. The practical takeaway is more limited: choose based on the finding network you want to rely on, not just the phone the tag can connect to.
