Apple’s new AirTag widens the net for lost things — louder, farther and greener

Apple’s refreshed AirTag, launched in China at 249 yuan, improves precision locating with a second‑generation UWB chip, extends Bluetooth range, and makes the speaker louder. The update emphasises recycled materials, deeper Apple Watch integration, and a secure item‑sharing feature for partners such as airlines, while reiterating existing anti‑stalking and privacy protections.
