How Apple made the spectacular iPhone X battery

Apple's iPhone X is about to make its debut, tomorrow (November 3) the Cupertino firm will put the terminal on sale in the Apple Store. The lucky consumers who manage to buy an iPhone X can enjoy a battery life usually reserved for Plus models.

We recently discovered an extensive analysis of the battery performance of the iPhone X. In theory, its battery lasts two hours longer than the iPhone 7 . According to the analysis, the battery lasts a full day, but users should continue to charge their iPhone X during the night.

Be that as it may, Apple has managed to incorporate a huge battery in the form of "L" on the iPhone X. The reason for this technological breakthrough has not to do with the development of a new energy density, but with the implementation of a much smaller motherboard (PCB) among the hardware components.

The large "L" shaped battery exists thanks to the motherboard

The tiny PCB inserted into the hardware of the iPhone X is due to a technology known as SLP . The leaks show a PCB with many more layers than a traditional base plate for iPhone thanks to the application of a processor and an RF signal linked with an interleaver.

In other words, as you will see in the image, the iPhone LCD (iPhone 8) of 2017 has a 10-layer SLP technology. On the other hand, the iPhone OLED (iPhone X) of 2017 has an SLP technology of up to 20 layers in a much smaller size.

In the following video you can appreciate the size of the new battery of the iPhone X with great detail. Normally a battery of similar size would only be available for Plus models.

How has Apple reduced the hardware components?

To make the hardware components smaller, Apple has had to find a way for the PCB elements to occupy much less. Basically, what they have done has been to complement and stack multiple components in one place . Something like the 10-nanometer manufacturing process of the A11 Bionic processor.

But reducing components of a PCB is not a simple decision. Several factors must be taken into account, such as research and development costs, space saving and impact on performance. Will Apple have achieved that everything works like a charm?
