Recently, after the launch of iOS 13, Apple launched several updates for the iPhone, iPad and other devices, and it was to fix problems, fill gaps and it is known as security updates. And since the beginning of January, Apple launched the beta version iOS 13.3.1 The first, and then attached it to the second trial version, especially after Apple reported several complaints from users of iPhone 11 devices that tracked websites even after closing the location services option in the settings, so an option was added to stop U1 chip In this update plus some other improvements.
After the launch of the iOS 13.3.1 updates, which is expected to be released soon, the user will be able to close this feature, but it is noticed that once the feature is disabled, the Bluetooth and Wi-Fi performance is affected by this other than disabling the features of the U1 chip, because the new chip strengthens wireless connections in general.
In response to users 'complaints that the chip is running all the time and collects the users' location, Apple said that the ultra-wide radio waves used in the U1 chip are an industry standard technology and are subject to international regulatory requirements that require them to be switched off at certain locations. Therefore, it must work all the time to help determine whether the "iPhone" is present in these restricted sites in order to disable ultra-wide radio waves and comply with regulations and laws. Apple says that the location of the device is done on the device and Apple does not collect user location data.
What is the U1 chip?
If you got an iPhone 11 of any class and don't know what the U1 chip is, you're dead Read the article In which we talked in detail about this chip, then you should continue, because your device has a terrible feature and you do not know anything about it.
The U1 chip works by relying on UWB technology or ultra-wide radio waves, which can be better, faster and more accurate than Bluetooth and Wi-Fi, and according to what Apple said on its official website, this chip enables wide transmission capabilities thanks to Ultra Wideband technology, which allows For iPhones to locate each other when they are close, and as soon as you point the iPhone to another person, the AirDrop feature will send files to him very quickly, and this will improve the AirDrop feature, which still has some problems, especially when trying to share files in crowded places full of people such as public places Conferences, parties and more.
UWB technology may be the best alternative to other communication technologies such as bluetooth and Wi-Fi, where bluetooth is an imprecise or even safe technology, and Wi-Fi, unlike UWB technology, which provides superior transmission capabilities twice the speed of other technologies and is completely secure thanks to the capabilities of It has encryption and uses UWB waves Time-of-flight technology To find out how long the signal will take to send to the device and return it, this means that the technology is able to determine the distance and even the direction, as for the bluetooth, it can measure distances, but based on the strength of the signal between the two devices, which can be affected by things other than the distance.

The truth, I feel it is worse
XNUMX Pro Max and me between the router is a small distance and picks up the signal with great difficulty
It picks up the signal, then separates, captures, disconnects, and so on
Very useful article, Apple should give us the option to turn off U1, but without affecting the wifi, thank you
