Apple has made some improvements to the iPhone 15 line, including the replacement of the U1 Ultra-Wideband (UWB) chip with the second-generation UWB chip. This new chip, along with AirTags and the Find My app, enhances location tracking capabilities. Compared to the first-gen component, the range of the new chip has been increased up to three times, allowing for a maximum distance of 50-60 meters (approximately 154-196 feet).

One of the lesser-known features of the iPhone 15 line is the ability to use the second-gen UWB chip and the Precision Finding interface in the Find My app to locate a specific person nearby who owns an iPhone 15 series model. A video demonstration by Teknofilo showcases how this feature works. The Precision Finding interface displays the distance in meters between you and the person you are tracking as a dot on the display, with a giant arrow guiding you towards the target.

However, it is important to be mindful of your surroundings while using this feature, as shown in the video where the user almost collides with another person while focusing on their iPhone screen. To utilize the Precision Finding interface, simply open the Find My app, select the person’s name, and if the Precision Finding feature is available for tracking, the “Find: Nearby” button will appear in the details card.

In terms of AirTags, the current range for Precision Finding using the first UWB chip is 10-15 meters (32-49 feet). In the future, AirTags 2 will be introduced with the new UWB chip, enabling users to track items located at longer distances using the Precision Finding interface. However, it is important to note that this functionality is currently limited to the four iPhone 15 models equipped with the new UWB chip.
