نخستین کالبدشکافی آیفون X اپل

The iPhone has come a long way in ten years—so long, in fact, that the design has cycled back a bit, and this iPhone looks more like the original than we've seen in a long time.

• Except of course for that camera bump, and shiny stainless steel rim, and glass back, and Lightning connector...

As was the case with the iPhone 8 earlier this year, Apple has banished the unsightly (and environmentally responsible) regulatory markings from the back of the iPhone X.

• Jony finally has the featureless smooth backplane you know he's always wanted. Hopefully these phones still make it to recyclers without the hint and don't get dumped in the trash.

Before we dive in blindly, let's get some 10-ray X-ray recon from our friends at Creative Electron.

Here's what we found:

• Not one, but two battery cells. That's a first in an iPhone!
• A super-tiny logic board footprint. Based on the overlaid solder points, it looks like there are two stacked layers.
• To make room for the extra front-facing sensors, the earpiece speaker has been shifted down quite a bit.
• There's a mysterious chip between the Taptic Engine and lower speaker—we're curious to see what's down there!

This pentalobe looks weirdly unfinished. The bottom screws are more like pins if we're honest.

• This screw moves the threaded section from the display to the steel frame, and extends the unthreaded section into a freakishly long pin.
• Our best guess is that this allows the display a bit of flexibility, while also allowing it to move its mounting bracket toward the interior of the phone, incidentally making room for a beefed-up Lightning connector.

Luckily, it looks like they haven't rearranged too much else, as our typical trifecta of iOpener, iSclack, and iFixit Opening Picks works as in the past.

Looks like sideways-opening iPhones are here to stay. Apple surprised us with this little trick on the 7 Plus, but by now it's standard.

This single bracket covers every logic board connector—we've never seen this kind of connector density.

• And once again, we're faced with tri-point screws standing sentry over any repairs once you get past the pentalobe screws guarding the door.
• Something tells us Apple doesn't really want us (or you) tinkering in here.

After freeing the massive unibracket from the logic board, we can finally steal a peek at the hardware powering Cupertino's latest flagship.

We'll get a better look at the hardware on the display later, for now we satisfy ourselves with an X-ray—turns out that mystery chip is mounted to the display!

• For a change of pace, the display lifts off and leaves the front-facing camera behind.

This body shot confirms the layout we observed in our X-Ray recon: most real estate is occupied by the new dual-cell battery, and the logic board has shrunk significantly.

The dual rear camera has a beefy bracket that looks like it might offer some bendgate-proofing support for the delicate components.

The cameras are additionally secured to the rear case with some foam adhesive to keep things from jostling out of place. These cameras really need to stay put for Portrait Mode and similar features to work their magic.

Surrounding the camera housing cover glass, you can see tiny spot welds likely holding the walls of the camera bump to the case.

We finally free this most-dense of logic boards to get a closer look.

Comparing the footprint of the two boards, the iPhone X motherboard is about 70% of the size of the iPhone 8 Plus board—that's a lot more floor space for battery.

How did Apple put even more tech in 70% of the footprint? By folding the board in half, of course.

The two halves are soldered together, so we got some help from our hosts Circuitwise and their BGA hot air rework station to separate the layers.

• With the pieces separated, we tallied the area of all of the separate layers, and added it up to 135% of the iPhone 8 Plus logic board's area. Way to go putting more into less, Apple.

The iPhone X logic board is the first double-stacked board we've seen in an iPhone since the very first iPhone (third photo).

• The downside of this clever design is that board-level repair will be extremely difficult—near impossible in some cases.

On the first half:

• Apple APL1W72 A11 Bionic SoC layered over SK Hynix H9HKNNNDBMAUUR 3 GB LPDDR4x RAM
• Apple 338S00341-B1 power management IC
• TI 78AVZ81 battery charger
• NXP 1612A1—Likely an iteration of the 1610 tristar IC
• Apple 338S00248 audio codec
• STB600B0
• Apple 338S00306 power management IC

Apple/Murata USI 170821 339S00397 WiFi / Bluetooth module

Qualcomm WTR5975 gigabit LTE transceiver.

Qualcomm MDM9655 Snapdragon X16 LTE modem and PMD9655 PMIC. But Apple is dual-sourcing the modem, and TechInsights found an Intel XMM7480 (PMB9948) in their A1901 model. Even though the modem is capable of it, Apple isn’t supporting Gigabit speeds with the Qualcomm part.

NXP 80V18 PN80V NFC controller module

And on the outside of the logic board sandwich:

• Toshiba TSB3234X68354TWNA1 64 GB flash memory
• Apple/Cirrus Logic 338S00296 audio amplifier

Okay, so Apple made a PCB sandwich, but how does it work?

• They created a third spacer PCB that lines the perimeter. And instead of connecting the two layers with a fussy flex cable, data travels along dozens of through-hole vias.

Here, the A11 SoC lies nestled at the center of the main board. You can get a sense of the 3D structure of the board from the X-ray photos. The cylinders around the edge are holes filled with solder connecting the two boards.

The new dual-celled battery has four pull-tabs, similar to the shorter ones we found in the 8 series, albeit in an entirely new orientation.

• The pull-tabs are adhered to the sides of the cells, rather than folded over the top, making the procedure a little trickier than usual.

This phone is packing a 10.35 Wh (2716 mAh at 3.81 V) battery, just beating out the 10.28 Wh 8 Plus battery, but a drop in the bucket compared to the Galaxy Note8 with its 12.71 Wh behemoth.

The dual-cell design is more of a space-utilization measure than a capacity-changing one. Two cells allows for more creative shapes and placement, to best take advantage of the space left over by shrinking the logic board.

We turn our attention to the top of the phone to find the much anticipated mini Kinect TrueDepth camera system! This system rallies a team of sensors to bring facial recognition to the X.

• Step one in this system: the flood illuminator embedded in the display blasts your face with infrared (IR) light.
• Next, the front-facing camera, marked in red, confirms the presence of a face.
• Then the IR dot projector, far right, projects a grid of dots over your face to create a three-dimensional map.
• Finally, the IR camera on the left reads this map, and sends the data to the phone.
• Under the hood, the X works some seriously fast software magic to bring all these pieces together and figure out if you're you, or your evil twin.

The end is in sight, and we're powering through the remaining components in the rear case.

• This first little bracket is covered in spring connectors and EMI grounding fingers, and has a ribbon cable stuck to the back.
• Next out is the lower speaker enclosure, replete with ooey gooey waterproofing adhesive around the port.
• And lastly, the Taptic Engine and famed barometric vent are freed. Apple's Taptic Engine continues to be a linear oscillator vibration motor.

In fine form as always, our teardown engineer demonstrates dual tweezer technique to remove the Lightning connector.

Good news for anyone with the wiggly charging cable blues: the Lightning connector is looking extra-reinforced, with a wider bracket that screws into the sidewall of the frame.

• It also features through holes for the exterior pentalobe screws to pass through and key into the display, as we saw earlier.

With the main assembly picked to bits, we turn our attention back to the display. The first thing to pop out at us is the earpiece speaker, newly redesigned with a cool duct to channel sound out of the display.

Carefully extricating the upper display components yields the most complex upper display component collection we've seen yet. It's home to a loudspeaker, microphone, ambient light sensor, flood illuminator, and proximity sensor.

After picking off all the modular bits, we're left with a bare display.

Time to get a look at that mystery chip! With a little help from our friends at TechInsights, we get a peek under the shields on the back of the display and find:

• A Broadcom touch screen controller, labeled BCM15951B0KUB2G.
• Also along for the ride: a new STMicro device we have not seen before, an OLED PMIC labeled 10 THADT733 X-139U.

Getting down to the X's bare metal, we run into another familiar piece to this densely-packed puzzle: the wireless charging coil.

• Oh, and everything attached to it, including the volume buttons, ring/silent switch, and an unidentified sensor bracket.

We also peel out the other crazy multi-function cable from the top of the phone. This assembly's home to the quad-LED True Tone flash and the power button, much like iPhones of yore.

Bonus round: What happens when you break the rear glass on your brand new iPhone X?

After lots and lots of heat, we sheathed the spudger and drew our Jimmy. Like the iPhone 8 and 8 Plus, The X features a seriously glued rear panel.

After all of our careful Jimmying, we're still stuck: Unlike the iPhone 8's single piece rear panel, the camera bump overlaps the rear glass, and is meticulously welded to the metal frame beneath.

In this classic hand-stuck-in-cookie-jar situation, we can either cut off our hand (the camera bump) or shatter the cookie jar (the rear glass). Great.

• We opt for the camera bump-ectomy for an intact glass panel. Those replacing a broken panel won't have any good options—and they'll have a heck of a time scraping out the shards of glued-down glass.

We hope you enjoyed your 22-course teardown meal. We found it very nutritious.
