Samsung Galaxy SmartTag 3 Launches with Cross-Platform Support and 790-Day Battery Life

Key points

• The SmartTag 3 adopts a squircle design without a built-in key ring, requiring separate cases for attachment to keys or luggage.
• It offers industry-leading battery life, with up to 550 days in normal mode and 790 days in power-saving mode, using a replaceable CR2032 battery.
• Cross-OS support allows users to share tracking data with friends or family using iOS or non-Samsung Android devices via the SmartThings app.
• New features include Place Notifications for geofencing, movement detection alerts, and location history stored for up to seven days.
• The tracker uses Bluetooth 6.0 Channel Sounding for Compass View up to 60 meters and integrates with the Galaxy Find Network for broader detection.

Background

This is the third generation of Samsung's item tracker, following the SmartTag 2. Previous models were restricted to Samsung devices, limiting their utility for mixed-platform households. The new device competes directly with Apple's AirTag and Google's upcoming Pixel Tag, aiming to capture users who value cross-platform compatibility and long battery life. Samsung's earlier archive coverage confirmed the initial announcement details, including the pricing and release timeline, which align with the current launch.

How outlets are covering it

Gizmodo emphasizes the tracker's improved range and 'centimeter-level' precision, highlighting its competitive stance against Apple's AirTag. The Verge notes the design change, specifically the removal of the built-in key ring, which necessitates purchasing additional cases for direct attachment. Samsung's official newsroom focuses on the 'industry-leading' battery life and the utility of cross-OS support for sharing tracking data with non-Samsung users, such as dog walkers or family members. All sources agree on the core specs, including the 35% size reduction and the November US release date.

Why it matters

The introduction of cross-OS support breaks Samsung's previous ecosystem lock-in, making the SmartTag 3 a viable option for households with mixed Apple and Android devices. This move intensifies competition in the Bluetooth tracker market, forcing Apple and Google to consider compatibility features. The extended battery life and smaller form factor address common user complaints about previous trackers, potentially increasing adoption rates for tracking pets, luggage, and keys.

What to watch

The Galaxy SmartTag 3 will be available in South Korea starting October 7, 2026, followed by a US launch in early November. Additional global markets are expected to receive the device in 2027. Samsung has also released official accessories, including silicone and loop cases, to facilitate attachment to various items. Future updates may expand Bluetooth Channel Sounding support to more Galaxy devices, currently limited to the Z Fold8 and S26 series.
