Samsung Galaxy SmartTag3 review

The Galaxy SmartTag3 is the tag to buy if you carry a Samsung phone. Samsung says it is about 35% smaller by volume and 33% lighter than the SmartTag2, and it reports through the Galaxy Find Network, which Samsung puts at more than 900 million participating devices. For luggage the standout is the alert set: Place Notification tells you when a tagged item enters or leaves an area you draw, Movement Detection Alert flags when it moves, and Location History shows where it has been, so you can see a bag leave the airport or a hotel storage room. Battery life is rated up to 550 days, or 790 days in Power Saving Mode, which beats every coin-cell tag here. Compass View uses Bluetooth 6.0 Channel Sounding for direction and distance from up to 60 m, with UWB taking over up close. For the first time iPhone users can check the tag through SmartThings Find, though it is still a Galaxy-first device.
