Your iPhone is getting enhanced Bluetooth tracking with iOS 27 - but there's a catch

Apple’s WWDC reveal includes an understated but significant upgrade: iOS 27 will introduce Bluetooth Channel Sounding to enhance Find My tracking on devices that support Bluetooth 6.3. The feature promises centimeter-level location accuracy and improved third-party device support, potentially widening the Find My network beyond Apple products. While it could improve finding items such as Bluetooth headphones and digital keys, adoption will be gradual, with developers testing in the coming months ahead of a fall public release. Channel Sounding builds on Bluetooth 6.0 concepts and complements existing UWB-based Find My functionality, offering a more universal ultra-precise localization framework.
