When Apple introduces the remote Siri which is changed next to the new 4k Apple TV, there are general questions: why does Apple not provide the same Ultra Wideband item tracking technology that you found in the airtags? The company finally has an explanation, although it might not shake you. Apple VP Tit Twerdahl told Mobilesirrup in an interview that there is no need for tracking like actag because it doesn’t just stay at home, but it’s thick enough so “won’t fall on your sofa pillow.” You tend to lose it in the first place, in other words.
It will not be surprising if there are other factors too. UWB support can increase remote costs, for example. It will not affect the battery life, because airtag is designed to be passive and rule up to one year of use even with standard cell batteries. Siri remote uses a much higher capacity lithium package.
Whatever the reason, you must find control in ancient ways – or use your iPhone until you find a long distance hiding under the pillow.
