The batteries of unofficial premises Apple that are placed on the iPhone lack an important piece, a microcontroller that carries an authentication key provided by the company.
With this new software, Apple You will be able to identify the phones that received a non-original battery and proceed to the blocking of the equipment since they do not have the certification or guarantee of the factory.
Once the software identifies that the battery is not the original, immediately, send a message to the user who will say Service and the owner of the equipment should quickly go to an authorized technical service of Apple.
As explained in the specialized site iFixIt, even if the user places an original battery in the device, if it is not authorized by Apple It just doesn't work.
This initiative is a declaration of war on technical services not approved since Apple, by blocking the batteries of the factory iPhones, it forces the owners to pay more money to avoid a blockage of devices and to go to an official technical center to change the battery of their device.
