iPhone X Teardown Reveals Stacked Logic Board, Dual-Cell Battery, 3GB RAM, and 2716mAh Battery


It has just been a few hours since the iPhone X went on sale and the folks over at iFixit have already gone ahead and posted a teardown of the device.

The teardown reveals some interesting and key details about the iPhone X and shows how Apple has done an incredible work from an engineering viewpoint to make it happen.

Firstly, due to the reduced bezels, the iPhone X had less internal space for all of its components. Thus, to maximise space for the battery, Apple ended up making the iPhone X’s logic board smaller.

Apple has essentially folded/stacked the logic board in half on the iPhone X and soldered them together. Due to this, the iPhone X logic board occupies only 70 percent of the space when compared to iPhone 8 Plus. However, when this stack board is spread out, it is actually 35 percent bigger than the logic board used inside the iPhone 8 Plus. The additional space saved allowed Apple to include the required components for FaceID.

As if this was not already impressive enough, Apple has also used a 2-cell battery on the iPhone X. This dual-cell approach allowed Apple to get creative with the available space and make the most effective use of it by including a 2715mAh battery on the device. No wonder despite having dimensions similar to a 4.7-inch iPhone, the iPhone X offers 2 hours better battery life than it.

The teardown also reveals that Apple has used a beefy bracket for the dual rear camera setup at the rear for extra rigidity and strength. The camera sensors have also been secured to the rear case using adhesive to ensure they don’t budge from their place. Lastly, it also confirms that the iPhone X comes with 3GB RAM.

The iFixit team notes that the internals of the iPhone X is among the most densely-packed they have ever seen. Its internals bear no resemblance to that of the iPhone 8 or the iPhone 8 Plus with which the handset shares a lot of internals.

Overall, the iPhone X internal design has been done in such a way so as to facilitate screen and battery replacement. However, other components used inside the device are not modular in nature which means replacing them can be an expensive process. Replacing that 5.8-inch OLED display is also an expensive affair which can cost you $279. The iFixit team gave the iPhone X a repairability score of 6 out of 10.
