Which Apple devices have the U1 chip?

For the new functions in the “Where is?” Network and for the use of Apple AirTags, the U1 chip for use. The “U” stands for “ultra broadband”. But in which Apple devices is the U1 chip installed for the exact wireless connection and location? We clarify that in this guide. You can also find more information about the component and its function here. Which battery is used in the Apple AirTag, By the way, you can find out about this with this link.

Which Apple devices have the U1 chip?

In the following list you will find those Apple devices that have installed the U1 chip. It enables them to communicate via ultra-broadband and to locate other devices very precisely. The chip has been installed since 2019, as you can see here:

  • iPhone 11
  • iPhone 11 Pro
  • iPhone 11 Pro Max
  • iPhone 12 mini
  • iPhone 12
  • iPhone 12 Pro
  • iPhone 12 Pro Max
  • Apple Watch Series 6
  • Apple HomePod mini
  • Apple AirTag
  • Third-party devices and trackers for the “Where is?” Network

What can and does the Apple U1 chip do?

Perhaps you have already noticed the direction display when using AirDrop on newer iPhones from the 11 or 12 series. The U1 chip from Apple ensures this precise location and helps to send data to precisely the devices to which they should be sent - simply by pointing the device from which you want to send. 

If an iPhone is pointed at another iPhone, an iPad, a Mac or the like, the device appears first in the AirDrop list for sending files. In addition, the Apple U1 chip ensures extremely precise location in the “Where is?” Network. That is why it was also installed from the iPhone 11 onwards, because AirTag was already planned there. 

U1 Chip: What is Ultra Broadband?

Ultra-broadband means that radio signals with high frequency are used in order to precisely localize the devices in the vicinity if the range is short. This enables location-based communication between HomePod mini speakers as well as the device-specific use of AirDrop as described above. 

With the Keynote on April 20, 2021 Apple has now also introduced AirTag. The trackers, which were leaked in advance as "AirTags", use the U1 chip and ultra-broadband radio to enable objects (luggage, keys, wallets, etc.) to be located quickly and extremely precisely. With the component, Apple devices get a kind of "spatial vision" on a digital basis.

    I can't find anything on the Internet, but I can hardly imagine that the new iPad Pro 2021 (the new one with the M1 processor) shouldn't get a U1 chip. I mean, the Pro 12.9 2021 is the top model, the S-Class, so to speak - and then no U1?
