Losing your keys right before you have to leave is one of those small disasters that feels disproportionately catastrophic. Bluetooth trackers were supposed to fix that, and they mostly have, except for one nagging issue: the good ones tend to work best inside a single ecosystem. Apple’s AirTag is excellent if everyone around you has an iPhone. Most of the world, however, does not. That’s the gap Xiaomi is aiming at with its new Tag, unveiled at MWC 2026.
The Xiaomi Tag supports both Apple Find My and Google Find Hub, which matters more than it might sound. Bluetooth trackers don’t locate your lost bag on their own. They rely on other people’s phones nearby to silently ping the tag’s location back to you. The larger the network of phones, the better your odds of actually finding something. Android outnumbers iPhone significantly across most of the world, so a tracker that taps both networks has a meaningful practical advantage over one that doesn’t.

The two networks don’t run at the same time, so the Tag operates on one or the other depending on your setup. Still, the flexibility alone puts it ahead of most alternatives. Connectivity runs on Bluetooth BLE 5.4, and for Lost mode, Apple Find My users can tap any NFC-enabled phone to pull up the owner’s contact details without downloading a single app. That last part is a small but genuinely thoughtful detail.
Physically, the Tag weighs 10g and measures 46.5 x 31 x 7.2 mm, compact enough to slide into a wallet without creating a noticeable lump. IP67 dust and water resistance means rain and accidental puddle encounters are not going to be a problem. The battery is a removable CR2032 button cell, rated for over a year of life based on four sound searches per day, and the app sends a low-battery alert before it dies on you.
There’s an accelerometer inside, and the app can send left-behind alerts when the Tag separates from a location you frequent, though that feature currently works only on Apple Find My. Lost mode lets you attach your contact details and a message, so a stranger who finds your luggage can get that information either through an Android pop-up or an NFC tap on an iPhone, no app required on their end. It’s the kind of friction-reduction that makes the difference between someone actually returning your bag and just walking past it.
An anti-tracking alert is also built in, notifying you if an unknown Tag appears to be following your movements. Xiaomi notes that coverage depends on the Find network’s own implementation, which is an honest caveat that most trackers quietly bury. The Tag is available as a single unit or a four-pack, which is useful if your wallet, keys, backpack, and luggage all feel equally likely to disappear at any given moment.
