Galaxy SmartTag 3 is 35% smaller by volume and 33% lighter, while energy-saving mode extends battery life to 790 days. It works with iOS and Android devices, and its smaller body should fit more easily in a wallet or bag. Optional accessories let owners attach it to a pet's collar.
Samsung has replaced the bulkier design with a rounded aluminium finish. The new shape should feel more comfortable in a pocket or among personal items. Android Police cited the model number EI-T5900 as an early sign that a third-generation SmartTag was on the way.
Standard use is rated at up to 550 days. Energy-saving mode lifts that figure to 790 days. The device uses a replaceable button battery and carries an IP67 rating for resistance to dust and liquids.
Samsung will sell the tag in Black and White. It has not yet announced official pricing.
The core device no longer includes a hanging ring or keyring. Users can instead choose a silicone case with an official keyring or a case with a strap. These options give the tracker different uses without adding size to the tag itself.
Reports from 9to5Google, Android Headlines and AndroidPure say Samsung will end SmartTag support in SmartThings Tracker on October 31, 2026. The trackers will keep working, but Samsung is directing users to the separate Samsung Find app and the Galaxy environment to locate them.
Galaxy SmartTag 3 pairs Bluetooth 6.0 Channel Sounding with ultra-wideband technology. Compass View can guide users toward the tag from up to 60 metres away, with directions becoming more precise as they get closer. UWB provides directional finding near the object, while Bluetooth detects it from farther away.
The Galaxy Find Network backs that guidance. Samsung says it includes more than 900 million compatible devices worldwide. They can locate a missing tag while using little energy, without any visible action from the people carrying them.
For households with different devices, iOS support may matter most: Galaxy phones and iPhones can now use the same tracker. Industry reports have described wider compatibility as one of Samsung's basic steps toward serving households with devices across platforms.
Location Notification can alert users when a tag leaves a defined area, while Location History records where it has been. SmartThings can also send an alert when it detects movement. That could help track a pet leaving a garden or show when a bicycle or personal mobility vehicle starts moving unexpectedly.
Lost Mode can display a message when someone finds and scans a missing tag. The button can also start routines through SmartThings IoT Control.
Notify When Left Behind alerts users when a mobile device loses its connection with a configured tag. Samsung says location data remains encrypted.
Samsung executive Jay Kim said the product was shaped by requests for a simpler, more convenient way to locate belongings and pets. The company plans to bring Galaxy SmartTag 3 to major markets, including Spain, over the coming weeks.
Samsung has not disclosed the recommended retail price. The previous generation initially had a recommended price of 39.90 euros.
The new model tackles practical limits in size and battery life, while adding platform support. Its 60-metre guidance and automatic alerts, alongside pet-focused accessories, extend its uses beyond finding a lost object.
The price remains unknown. Until Samsung confirms it, Galaxy SmartTag 3's strongest case rests on its specifications: a smaller tracker built for long-term everyday use.
Buyers should also consider Samsung's move from SmartThings Tracker to Samsung Find after October 31, 2026.
