Apple's newest iPhone has a mysterious "U1" chip inside of it – and nobody is really clear what it does.
The company unveiled its new iPhone 11 and iPhone 11 Pro this week, revealing an array of camera upgrades and colour changes as well as vastly increased battery life and performance.
For now, it is only being used for a new feature that uses Apple's AirDrop technology, and allows people to point their phones towards another device and send files between the two. The chip can be used to precisely locate other devices, Apple said, meaning it can know exactly where it is pointing, writes The Independent.
The Apple website does provide some information about the new chip. Somewhat ironically, it appears under a heading indicating that it will allow the phone to be more "precise".
