简介

We’ve torn down the mini iPhone and the two medium iPhones, but we saved the biggest for last: the iPhone 12 Pro Max. If you caught our livestream last week, you got a sneak peek at what it’s packin’—but we wanted more (and our DMs tell us you do, too)! Time to give this full-bodied phone the full teardown treatment.

To put the iPhone 12 Pro Max camera to the ultimate test, we used it to secretly snap two photos in this teardown with the Halide camera app. Can you spot them? Place your bets, and then scroll down to Step 14 for the answer.

P.S. If you like what you see, you should probably follow iFixit’s YouTube channelInstagram, and Twitter—because if you enjoy teardowns and nitty-gritty tech findings, those are the best places to catch ’em all. While you’re at it, subscribe to our newsletter so you can keep up with our other shenanigans. P.P.S. Don’t miss our Holiday Gift Guide for the latest iFixit deals, and keep an eye out for something that rhymes with bee zipping coming this Monday.

这个拆解是不是维修指南。 要维修你的的iPhone 12 Pro Max,请使用我们的维修手册

  1. Once more unto the breach! Here are the stats on this final iPhone boss:
    • Once more unto the breach! Here are the stats on this final iPhone boss:

    • A14 Bionic SoC with fourth-generation Neural Engine

    • 6.7 inch (2778 x 1284 pixels) Super Retina XDR OLED display with P3 wide color gamut and True Tone

    • 12 MP triple camera system with wide angle ƒ/1.6 (OIS), ultra-wide angle ƒ/2.4, and telephoto ƒ/2.2 (OIS) cameras, with a LiDAR module

    • 6 GB of RAM and 128 GB of storage (256 and 512 GB configs available)

    • 5G (sub-6 GHz and mmWave connectivity), plus 4x4 MIMO LTE, 802.11ax Wi-Fi 6, ultra-wide band (UWB), NFC, and Bluetooth 5.0

    • MagSafe 15 watt wireless charging

    • IP68 rating, water resistant to a maximum depth of 6 meters for up to 30 minutes under IEC standard 60529

  2. 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.

  3. 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. One item we're especially interested to see: the wider L-shaped battery—especially because we were bummed by the boring rectangle in the Pro. The Max alone holds onto an L, but, hey, other iPhones? You're still a W in your own special way.

  4. 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.

  5. 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.

  6. 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.

    • 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.

    • This sensor also has that other trick up its sleeve: sensor-shift image stabilization.

    • 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 new hyper-pocketable Minnow Driver Kit.

    • If you've got a keen eye and would like your own personal Minnow, enter our giveaway here and tell us which two steps in this teardown contain a photo shot on an iPhone with the Halide camera app.

    • 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.

  7. 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.

    • This is a slight step down from the 15.04 Wh pack in the iPhone 11 Pro Max, and it definitely falls behind the Galaxy Note 20 and 20 Ultra (16.69 Wh and 17.46 Wh respectively).

  8. 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. The 12 Pro Max benefits from a detached, modular SIM reader like in the 12 and 12 Pro—which also happens to be a bit more repair-friendly. 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.

  9. 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

    • 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.)

    • PS: We're pretty impressed with the new camera's capabilities—If you didn't already guess, the two images we shot on iPhone are here and here. Congrats to our lucky prizewinners who guessed correctly!

    • Oh by the way, our iPhone 12 Pro Max thankfully gave us no trouble in our camera repair tests—unlike the standard iPhone 12. Let's hope those bugs were just a fluke.

  14. 最后的想法
    • 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.

Adhesive pull tabs are wonderful. I wonder why Apple won’t use them on their Macbooks (and why more electronics designers aren’t using them as well). They’re low-cost, very convenient, take up very little space, and are satisfying to pull.

Can’t help thinking could you retrofit a USBC port instead of lightning ?

gronager - 回复

The lightning port is probably pair the the phone like all the rest of the components.

Tristan Haugh -

i have no idea what i was typing here lmao

Tristan Haugh -

Would it be possible to get a closer look at the back of the camera sensor, or more importantly, how the cables connect the sensor shifting mechanism to the base frame? It’s quite possibly the one of the most interesting engineering problems in it and I can’t seem to figure out how it works from the photo above - would anyone be able to explain or share more detailed images of this mechanism?

Thanks!
