The disassembly of the iPhone 11 Pro reveals a smaller logic board, a larger battery

iFixit has disassembled Apple’s new iPhone models, which tells us more about the differences with last year’s phones. iFixit recorded a live video of the disassembly of the iPhone 11 Pro and wrote a guide for the iPhone 11 Pro Max.

The first big difference is that the batteries in the iPhone 11 Pro and iPhone 11 Pro Max are much larger than the batteries in the iPhone XS and iPhone XS Max.

On the iPhone 11 Pro Max, the device is .4 mm thicker and the screen is 0.25 mm thinner. As John Gruber expected, dropping 3D Touch from the iPhone line makes the screen a bit thinner. 3D Touch required an additional layer under the screen to record the pressure on the screen.

It may seem a small difference, but it frees up some space for the battery. The iPhone 11 Pro and the iPhone XS have the same L-shaped design of a single cell. But the Max version has been updated to use the single cell design instead of two cells.

The result is that the iPhone 11 Pro Max now has a 3,969 mAh battery compared to a 3,179 mAh battery in the iPhone XS Max. It represents an improvement of almost 25% year-over-year for the Max battery.

These hardware improvements combined with a more efficient A13 chip system create some significant improvements in the battery’s lifespan for the user. Apple claims that the iPhone 11 Pro and the iPhone 11 Pro Max last up to 4 hours and 5 more hours, respectively, compared to the previous generation.

In other news, the camera module is much larger in this year’s new device (as expected). Apple managed to put a third camera by reducing the size of the logic board.

The logic board has the same double layer design that was first introduced with the iPhone X. It’s like a chip sandwich club. Although Apple and Qualcomm have resolved their multi-million dollar lawsuits, the modem on the iPhones 11 Pro is still manufactured by Intel.

When it comes to things we still don’t know, iFixit couldn’t determine how much RAM there is: Steve Troughton-Smith believes there could be 2 GB of RAM dedicated to the camera that you wouldn’t notice at the landmarks.

Similarly, there are now two battery connectors instead of one. It is difficult to say with certainty that the second connector has been added for bilateral wireless charging; I could be there for many different reasons. It is rumored that Apple wanted to add a reverse wireless charge but removed the function at the last minute.

Overall, iFixit grants a 6 out of 10 reparability score. IPhone XS models also scored 6 out of 10.
