Last Friday, Apple finally announced the death of AirPower. Stand for wireless charging never came out
So why Apple decided not torelease AirPower? Even the beta versions of iOS 12.2 indicated that the release of AirPower is inevitable, but something changed at the last moment. AirPower might not meet Apple's high standards due to overheating problems and interference due to the location of the cores on the 8-7-7 system.
Each core in the stand creates its ownelectromagnetic field. This field charges your smartphone wirelessly, generating electricity. The problem is that each core also generates some noise with interference. Usually in wireless charging 3-5 cores, so that interference is easy to manage.
Interference of one core is not a problem, but each coregenerates different waves. When these waves are encountered, the interferences combine, and this increases their power. This can be compared with the collision of two waves in the ocean, which are combined into one even higher. When interacting with each other, radio frequencies become even more powerful.
This can cause serious problems that threaten the lives of users.
Over time, interference accumulates and produces verypowerful signal outside. Because of this signal, someone's pacemaker or hearing aid may stop working. If Apple had such a problem, then the government could not approve of AirPower.
Apple planned to use kernels for AirPowersystem 8-7-7, so it is not surprising that there are problems with overheating and interference. The company wanted to add as many cores so that you could place the device anywhere on the stand, and it would start charging. For other wireless charging, you need to put the smartphone exactly in a specific place, otherwise it will not start charging.
Most likely, AirPower was tested only inlaboratories, and later the company realized that charging does not meet safety requirements. By this time it was too late to change something, and the company decided not to release AirPower.
A large number of cores also means that Apple has invested too much energy in a very small device, and this always leads to problems with overheating.
