In case you haven't heard, square is the new round... again.

Sorry to break it to you, but size does matter—at least when it comes to camera sensors. To achieve their alleged 87% improvement in low-light performance, the 12 Pro Max uses the biggest sensor in an iPhone yet. But before we nerd out on cameras, let's compare iPhones to iPhones:

Making our way around the iPhone clock, we've got a green iPhone 11 Pro Max, a gold iPhone 12 Pro, and a blue iPhone 12 Pro Max.

If big things are your thing, the iPhone 12 Pro Max delivers. Everything is bigger—even the camera bump.

Friends don’t let friends tear down devices without an X-ray blueprint. Lucky for us, we’re BFFs with the fine folks at Creative Electron who supply us with endless X-rays.

The basics of this iPhone look about the same as the rest of the 12 family, but the dark steel frame is Pro-only. Also, that MagSafe ring that didn't even fit in the 12 mini looks positively dinky in this Max.

A standard-issue heat and and iSclack application persuades this big Pro Max to let its guard down and share some secrets.

Like the other iPhones 12, the Pro Max opens just like a book: to the left, and with a good story inside.

Sure, it's not exactly like a book, but you get the point. With a little help from our guides, anyone can fix their iPhone.

But, iFixit, what if I don't need to fix my iPhone and I just want to stare at its gorgeous guts? We've got you covered with these nifty Pro Max wallpapers.

No time for frivolity today, we've got places to go and other teardowns to attend to. We head straight for the headline Pro Max feature: the new cameras.

The standard wide camera (bottom left in the group of three) is the source of all the 12 Pro Max chatter. It's reportedly housing a 47% larger sensor, allowing it to gather more light and thus, better photos.

With X-ray vision, we see that the standard wide's sensor is definitely bigger. We can also clearly see the four magnets surrounding it—telltale signs of Apple's brand-new sensor-shift image stabilization system.

Unmasked, the iPhone 12 Pro Max's primary (wide-angle) sensor is... large. Not unlike the phone it lives in.

Sometimes we're skeptical when a "Pro" feature only makes it into a larger, more expensive model. But there's a decent chance this sensor wouldn't fit in the cramped corner of the smaller iPhone 12 Pro without compromises.

This sensor dwarfs the iPhone 12's. It's 47% larger but with the same 12 MP resolution, so each pixel is larger and captures more light.

That's a technology many modern DSLR and mirrorless cameras use. When your hands shake, there are two main ways to stabilize the image: you can move the lens, or you can move the sensor.

Most smartphones that tout image stabilization use lens-based optical image stabilization (OIS) to smooth out jitters. Many internet battles have been fought over which stabilization technique works best in professional cameras.

Since Apple went out of their way to bring sensor-shift to the iPhone, either they think that's the way to go, or perhaps they just couldn't adequately stabilize the larger version of their new f/1.6 lens.

The loudspeaker and Taptic Engine are a snap to remove with the help of our hyper-pocketable Minnow Driver Kit.

The Max Taptic Engine sports a little black plastic sidecar. What for, you ask? It could help support the display, or maybe it's an extra battery bumper. Either way, it's unusual to find anything in an iPhone that seemingly just fills "unused" space—but not unprecedented.

Apple’s engineers seem satisfied enough with the battery capacity to give the Taptic Engine and speaker more room to boom. Compared to the mini, these bits are maxssive.

With those lower components conquered, we have the perfect angle of attack for those stretch-release battery adhesive tabs.

Don’t let that “L” deceive you—the Max has the winning battery out of all the iPhones 12, not just in power, but in technology. X-ray vision shows that the Max’s battery pack isn’t quite full to the brim, but it's darn close—and the high-tech shape allows it to turn the corner on capacity.

The Max power source weighs in at 14.13 Wh, tipping the scales against the 8.57 Wh mini battery and the 10.78 Wh 12 and 12 Pro.

With the Pro Max's logic board extracted, we're tempted to say it might be even more compact than the one in the iPhone 12 mini (bottom)—but, the mini's integrated SIM reader also leaves it at an unfair disadvantage.

Here's a quick X-ray view of the board before we slice it open. We'll have to take it one layer at a time, but it's neat to see them all at once. It's an amazingly intricate city of silicon driving these iPhones.

Fair warning, there were some minor casualties in today's board delamination. A little slip of the knife at 300° C is all it took to smear some of these chips right off the board. We blame our robot intern. Here are some of the bits he managed to salvage:

128 GB of Kioxia NAND flash memory

ST Microelectronics STB601A power management IC

Qualcomm's SDR865 5G and LTE transceiver, SDX55M 5G modem-RF system, and SMR526 intermediate frequency IC

USI 339S00761 WLAN / Bluetooth module

Avago 8200 high/mid-band power amplifier with integrated duplexer

Murata 1XR-482 mmWave front-end module

Let's get to that A14 straight away—and some of the chips around it.

Apple A14 SoC layered over 6 GB of Samsung K3UHCHC0MM-VGCL RAM

Apple 343S00437 power management IC

Possibly an STMicroelectronics wireless power receiver

Possibly an Apple/Cirrus Logic audio codec

Apple 338S00564-B0 power management IC

Apple/Cirrus Logic 338S00537 mono audio amplifier

Apple 338S00616, likely a display power management IC

And a few more chips on the same side:

Possibly a Bosch Sensortec accelerometer

NXP Semiconductor CBTL1614A1 display port multiplexer

Possibly a Maxim Integrated MAX8559 300 mA LDO regulator

Apple/USI U1 ultra-wideband chip

Texas Instruments LM3562A1, probably an LED driver

And finally, let's take another look at the storage side of the board:

Texas Instruments SN2611A0 battery charger

Broadcom BCM15960A0, likely Wi-Fi / Bluetooth SoC

Texas Instruments TPS68836 display power management

Apple/Cirrus Logic 338S00537 audio amplifier

Texas Instruments SN61280 battery DC-DC converter

Thanks to viewers like you, we did it! This season's fourth and final iPhone has been laid to rest in pieces. The only thing left to do? Load up some sweet teardown wallpapers.

The Pro Max is arguably Apple's finest iPhone-related achievement this year, adding some pretty demanding 5G tech with no obvious compromises to other components.

We're pleased to see this iPhone retain its high-tech L-shaped battery. Here's hoping those make a stronger comeback in the whole iPhone lineup next year—bigger batteries generally need fewer replacements over their lifetimes. (They're also just really cool.)

The iPhone 12 Pro Max earns a 6 out of 10 on our repairability scale (10 is the easiest to repair):

Screen and battery remain prioritized and reasonably accessible for replacement.

Most components are fairly modular and replaceable.

Some uncommon screws complicate all repairs, but reusable fasteners are preferred over adhesives.

Waterproofing helps reduce the frequency of some repairs while complicating others.

The glass back makes drops even more dangerous and requires a full case replacement if it breaks.
