New tracking devices might come to mind Air Tag It only works on newer iPhones only, but it turns out that you can use it with older iPhones, but not at all, as the matter has details, so owners of old iPhones will not be able to access all the AirTag features. So what you can and cannot do with AirTag if you own an old iPhone.
What are the old iPhones missing?
Older iPhone models do not have the U1 chip, which allows AirTags to determine the exact location. Works U1 Ultra Wideband processor Just like the echo positioning system a bat uses for flight.
The chipset emits impulsive radio waves and measures the time it takes for these waves to travel between compatible devices. Then this data is used to calculate the location of the device and is sensitive enough to locate the device within the inch limits.
As is well known to all, older iPhones are not equipped with the U1 chipset, as this chip was introduced in 2019 for the first time on iPhone 11. Instead of using an Ultra Wideband connection, older iPhones will connect to AirTag via Bluetooth.
You can still use the tracking with older iPhones
So if you bought an AirTag and you have an old iPhone that doesn't have a U1 chip, don't worry, the AirTag will still work with your phone as well. You can pair it with your phone and use it with the Find My app to locate the tracker attached to your keys or important things.
The tracking is handled by Apple Maps
Tracking on an older iPhone model will be handled by Apple Maps. You can open the Find My app and select the AirTag that you want to track. Instead of staying in the Find My app, your iPhone will be directed to Apple Maps, which will show you the path to take to find your AirTag.
Accuracy in tracking with older iPhones
What you lose with an older iPhone is accurate tracking. Precise tracking is a feature of AirTags that allows you to find it with very great accuracy.
If you lose your keys in a square, for example, a tracking window will pop up in the form of an arrow and a space to guide you to the exact location in which you lost it, down to just a few centimeters. Without careful tracking, you might only see that they are in the southwest corner of the place, for example.
What models don't have the U1 chip?
The iPhone 12 and iPhone 11 series are equipped with the U1 chipset. IPhone XS and earlier models do not contain the U1 processor. And also does not contain iPhone SE for 2020 also on the U1 chip for positioning.

Thank you for the effort

In my opinion, it is a matter of modernity and not manipulation or bad intentions from Apple ,,, before 2019 U1 technology was not ready and ripe for commercial use ,, and it is evident that modern technology does not work efficiently on old devices or cheap economic devices ,, for example, We board the plane and whoever has booked a first class seat is not like someone who has booked a business class, not like someone who has booked an economy class, and not like someone who has booked a seat in an economy plane, and all of these seats are produced by one company and technology in one time, but the matter is about serving you as much as you pay. ,,, There is no harm in this policy because it is fair and leaves it to you to choose with satisfaction, conviction and knowledge ,,, iPhone SE of economic devices and its external appearance is modern and technical, and its internal specifications serve your basic need and not entertainment, if you want to own the technology pay ,,, and this applies to All technologies; Because it is the source of livelihood for countries before it is the source of livelihood for individuals. Look at the economies of countries because of technology.
I liked the example of the plane, happy brother 😸
Well done, God bless you
Great article, it will change my decision if I think about buying SE for boys later
Good article, but I was surprised that the iPhone SE 2020 does not support the U1 chip, every time I discover why this device is so low !!!
It is certain that the price is related to the features included in the device
And not every user needs or cares about all the features sold with the device
But here in the iPhone SE 2020 an important point
Is (the battery)
Yes the battery
I chose this device
Because I do not need some features, including cameras, for example
But when I used it I was surprised by the bad battery
It does not help the person who spends most of his time away from energy sources
If the battery is fully charged in the morning
And I went to work
After seven hours, I can only find about 30%
Note that my use of the device is limited to calls and dealing with mail
And sometimes simple photography and correspondence through telegram or WhatsApp
Carrying a portable power supply is a cumbersome issue for me
So I see that this device is very excellent for those who only need some features and does not stay away from sources of energy (at home, office and car)
