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

  1. 即使我们正屏息凝神的等待Mini和Max的出现,但我们至少可以从另外两个家伙开始拆解。让我们看看他们的葫芦里,都卖的是什么药吧: 具备新一代神经网络引擎的A14 仿生芯片 6.1英寸(2532×1170像素)的超视网膜 XDR OLED显示屏,具备原彩显示,HDR显示功能
    • 即使我们正屏息凝神的等待Mini和Max的出现,但我们至少可以从另外两个家伙开始拆解。让我们看看他们的葫芦里,都卖的是什么药吧:

    • 具备新一代神经网络引擎的A14 仿生芯片

    • 6.1英寸(2532×1170像素)的超视网膜 XDR OLED显示屏,具备原彩显示,HDR显示功能

    • Pro 级别的1200 万像素相机系统具备超广角(ƒ/ 2.4)和广角(ƒ/ 1.6)相机和远摄(ƒ/ 2.0)相机以及LiDAR扫描仪

    • 板载存储为64 GB(iPhone 12)和128 GB(12 Pro)

    • 5G(sub-6 GHz和mmWave)连接性,再加上4x4 MIMO LTE,802.11ax Wi-Fi 6和BT 5.0

    • MagSafe 15瓦 无线充电

    • 防护等级提升到IP68级别,现在符合IEC 60529标准下,在最深6米的深度下保持长达30分钟而不进水。

    Unless something has changed in the past two weeks, a youtube channel bought two brand new 12’s and upon swapping components between the two, experienced multiple malfunctions. Starting with the logic board, simulating every component being replaced, then JUST swapping camera modules- to no avail. It seems the modules are ID’d to eachother and the logic board making DIY and third-party repair seemingly impossible without additional software-related steps being performed to “authorize” the replaced components …

  2. 还记得iPhone 4引入了像Braun一样的方形边缘时——开发者留在酒吧的原型手机泄漏的吗? 正方形设计回来了,宝贝!这次附带更少的丑闻。这些平坦的边缘震动了熟悉的设计,但也可能允许更多的屏幕空间,而不会使手机更大。 就像在展览馆走过历史通道一样,我们将iPhone 11 Pro,iPhone 12、12 Pro和iPhone 4叠放起来!

    • 那就对了!这些按时移的电话由我们的欧盟团队提供,该团队在美国睡眠(或末日滚动)时做得很快。

  3. 过去已经足够了,让我们打开这些东西吧! 通常,第一个障碍是几个讨厌的五角螺丝,但我们已经做好武装并做好了准备。 几个吸引人的把手和三角撬片应该可以让我们相对轻松地玩耍——我们之前玩过这款游戏。

  4. 现在从右边缘打开显示,这可能会使人群中的左撇子更容易维修。举手击掌! 自7代以来,iPhone就从相反的一侧打开。在此之前,5和6系列型号自下而上打开。在此之前,iPhone经过几乎完全的拆卸后才打开。 尝试在屏幕仍固定的情况下卸下连接器护罩,这有点奇怪,但是你可以操纵屏幕以为螺丝刀腾出更多空间。

    So, when the displays get cheaper in the future, you can possibly upgrade your display brightness. Cool!

    Dylan - 回复

    The brightness difference is likely that Apple is multi-sourcing the display between Samsung and BOE on the iPhone 12. The BOE panel probably can’t meet the same lifetime spec as the Samsung panel, so Apple is limiting the brightness on both of them to avoid a scenario where some iPhone 12s can get brighter than others. For the 12 Pro they presumably went with 100% Samsung panels and took advantage of the better specs to unlock higher brightness.

  7. 这些模块化SIM卡槽非常适合维修,如果说有一点奇怪的地方,就是——SIM卡槽,主板和电池的所有侧面均与以前的型号相反。 为什么选择switcheroo?吸烟枪是主板。自11代以来,它的规模已经极大地增长(可能是为了容纳高通的5G芯片),并且不再适合放在摄像机下方的旧房子里。 两种型号的扬声器都用 Phillips 螺丝固定在适当的位置,以便进行更换,而且它们都非常容易地可以卸下。

    • 与过去几年需要重新修复杂乱的粘合剂相比,这使扬声器的拆卸和更换过程更加容易。 由于更换电池时必须要先拆下扬声器,因此这也是一种周到的、明智的设计。

    • 令人失望的是,苹果公司放弃了为最新iPhone开发的独特L形电池设计。有传言指出,苹果使用更便宜的零件来抵消5G的成本,这似乎证明了这一点。

    Yes, the batteries are serialized! We swapped the official batteries between the two iPhones and got a “Not a genuine Apple battery” warning in the menu.

    Arthur Shi -

    I posted this in the general comments before seeing the comments section for each step so am re-posting the same comment here…

    On your 11 Pro Max teardown (and maybe on the smaller Pro teardown as well) you gave us thickness (4.6mm), volume (23.8 cubic centimetres) and weight (59.6g) numbers for the internal battery. I’d be really interested in seeing those three numbers for the 12 Pro battery and, when you do the teardown for the 12 Pro Max, for that battery as well. Thanks.

    Julian Anon - 回复

    “…iPhones. Rumors pointed to Apple using cheaper parts to offset the cost of 5G, and this seemingly bears that out.”

    Or you could argue that Apple used a more expensive but more power efficient 5nm processor to remove the need for a larger battery and thereby lose the unpleasant stress point in the larger L shape battery. It just depends on what you want to see.

    And while we are on the subject, why do iFixit still not sell spare parts for your own products. You’re so keen that everyone else should for theirs, but you don’t.

    I think the A14 is layered over LPDDR4X, not LPDDR4 as this article currently indicates. Your previous teardown of the iPhone 11 Pro shows the A13 over LPDDR4X and the teardown of the iPhone XS shows the A12 over LPDDR4X. It is unlikely that Apple has reverted to LPDDR4 for the iPhone 12 Pro.

    The Micron MT53D512M64D4UA chip is better described as an LPDDR4X SDRAM.  According to the Micron DRAM Component Part Numbering System the MT53D prefix decodes to (MT = Micron Technology, 53 = LPDDR4, D = 1.1V Vdd / 0.6V Vddq),  LPDDR4X is identical to LPDDR4, except that the I/O voltage (Vddq) is reduced to 0.6 V from 1.1 V, which appears to be the case for this chip.

    My guess for having 2 mmWave antennas in the specified locations is 2 possible use cases, because of the nature of mmWave signals being easily blocked.

    So what i meant, if look at the side view of one ring segment, i think it are basically 3 magnets next to each other, this would be stack able to connect the same structures above:

    - + -

    maybe also only the first 2 „virtual“ magnets are used wich get more like your picture but i think you have at least to put in polarity on the side view, and if they have it also on top view you have to draw it in 2D..

    3gfisch - 回复

    The linked polarity diagram is definitely incorrect. These magnets are non-standard and have a dual set of poles for EACH magnet (The outer ring is North up, and South down, and the inner ring of the magnet is South up and North down).

    • mmWave再见,高5G到处!此拆解是一个总结。

    • 它正在塑造成为5G世界,而苹果正处在其中。看来他们必须做出一些严肃的设计折衷,才能为闪亮的5G新组件腾出空间。恰当的例子:过去的主板和电池增益都消失了。他们将被错过。

    • “瘦弱”的电池,相对来说技术含量略低,不再是优雅的L型。逻辑板的尺寸膨胀,放弃了近年来的小型化优势。 Taptic Engine看起来更小,扬声器是一种新的形状-可能不会减少,但会有所不同。

    • TapticEngine较小,而扬声器则是新形状——可能不会减少,但会有所不同。

    • 从整体上看,这并不是“一千个死亡”,但看到这种新兴技术的让步很奇怪。在所有可能的苹果创新中,这是最没有创造力的。

    • 但!至少新的5G挖掘与苹果的可靠屏幕和电池维修程序没有什么区别。 在给分数打分之前,还有一件事。

    As stated above, for the 12 pro it appears the taptic engine is bigger than the unit in the 11 pro.

    Also one of the first things I noticeded on my 12 pro was the speakers, they seem tinnier and not as loud. I have to test them next to my 11 pro before I sell the 11.

Really happy to see that Apple is bringing back Magsafe to at least some of its products. I wonder if it’ll eventually lead to completely sealed phones with no physical connector (and therefore no connector wear), but I think that would make data recovery harder.

Magsafe (or any other magnetic connector) is really convenient and pretty durable. I wonder why Apple abandoned the standard for a while.

Ethan Zuo - 回复

Magsafe for macbooks is the most intelligent charger connector ever made, illogically they stop using it, I agree with you, is good to see they're bringing back the idea. Regards the fully close devices, can be done and use external pogo connectors (or whatever are they called, the copper dots on some devices/tables to attach keyboards)

Jeffery.Y - 回复

We’d love to know the dimensions of the magnet array on the phone. What is the inside diameter? What is the outside diameter? What is the length of the line of magnets? What distance from the center of the magnet ring does the line of magnets start and stop?

Concerning the charger itself…. What is the inside diameter of the ring? What is the outside diameter of the ring?

It would be great if you had a precise scale reference in a straight-on photo of the magnet array in the phone.

Thanks for your work!

Could you probe the magnet ring with a small magnet to see if the polarity alternates?

smurpster - 回复

Agreed! Also can we get a teardown on the magsafe charger? Just probing my charger with a small magnet it looks like it has one outer ring that is one polarity and an inner ring that is the other polarity.

That magsafe charger just peaking open is killing me! Don’t leave us hanging on it! Also, please don’t forget to teardown the usb-c connector. It’s quite large and maybe has the USB PD chip in it or something…

jazz weisman - 回复

I want to see if the display chip on the pro model is actually 120hz capable and if the one on the non pro is different. It would be neat to see if Apple actually put in everything necessary to activate 120hz later since the pro panels I believe are capable. Also it would be cool to see how they improved water resistance this year yet again. And maybe seeing if they added any better thermal dissipation system since the 5g chips are gonna get a lot hotter than previous chips and plenty of android phones have had really good cooling for awhile.

Judah Singh - 回复

For those asking, Apple published a revision to their Developer Style Guide for physical accessories that includes all of the information you could need about the MagSafe standard.

60HzNSTC - 回复

Hello! Our EU team has taken apart a set of iPhone 12 and iPhone 12 Pro phones, while we tore down the US-only pair. We can confirm that they all use the 10.78 Wh rated battery.

Arthur Shi -

Apple is using a braided copper coil in the charger. I believe they are the only ones doing this.

Colin Stalter - 回复

This is normal. It’s called “litz wire”, you can read about it on wikipedia. It mitigates the “skin effect” that causes electrical losses to be higher at high frequencies.

David Perlman -

-The stranded wire in the coil is called “litz wire”, it’s not regular stranded wire, it’s a bundle of separately insulated strands for the purpose of avoiding the “skin effect” for high frequencies.

-The etched copper sticker looks like it’s an RF antenna for near field communication. Ethan Zuo pointed out that eliminating hardware connectors would make data recovery harder but I believe we will eventually find out that this new magsafe standard is not only for charging but also a high bandwidth data connection that can serve the “console” functions like data recovery. So basically just as good as a physical connection.

David Perlman - 回复

Hi David,

Thanks for the cool bit of info about litz wire! As for the copper sticker, I originally hypothesized that it was some kind of RF antenna also. I’m not so certain now—if you look closely at this photo, you can see that the sticker traces were attached by four flex wires. These wires route underneath what seems like a very brittle disk (maybe ferrous?), where they attach to the underside. It looks like they’re not attached to any active components. I wonder if it’s some kind of RF/magnetic flus resonance, efficiency, or shielding system.

Arthur Shi -

The copper sticker is almost certainly for NFC. The ring animation that was shown during the presentation when the phone is connected to the MagSafe charger is done through an NFC handshake. This is also how the phone knows it can try and charge at the higher wattage. NFC is also how the phone shows the ring animation for MagSafe cases (my red case creates a nifty red ring animation when I put it on).

I would guess that the iPhone 13/14 will eschew a physical connector and instead use a combination of the NFC from MagSafe and a version of the U1 chip (maybe a U2?) for high-speed close range data transfers without needing a physical connection. I don’t think we will see that type of high-speed data transfer on the 12 however as Apple looks to get MagSafe accessories out there.

David Fischer -

What is the matte colored area on the right side below the power button?

James Cannon - 回复

A window for the 5G mmWave antenna. See steps 2 and 13, only the US models have this.

James - 回复

Have you guys tried attaching the camera module from the 12 to the 12 pro to see if it works? Most probably the only difference between the two boards are one or two config resistors that will because obvious once China leaks the schematics.

Mihai Zaim - 回复

Even if it plugs in, firmware differences will likely prevent using the additional hardware, and the opening for the LIDAR and extra camera appear to be part of the case

Tony -

Hi Mihai,

We did! The non-Pro camera connectors have some missing pins compared to the Pro camera connectors, but they fit the Logic Board sockets. When we swapped the camera modules in either direction, both normal and wide-angle cameras worked, but were locked in 1x zoom—which locked the telephoto camera from activating.

Arthur Shi -

Not sure how you can claim Apple got rid of the “L” battery to cut costs, when there is clearly no room inside the phone to fit a larger battery of any shape…

Could you check this: https://www.youtube.com/watch?v=FY7DtKMB... Some people are saying that the iPhone gives a message and makes features unusable when swapping out parts. Apparently only Apple can now Swap out parts since the iPhone tells you that parts are not genuine and can detect third party or even own party components which have been swapped out.

Hi iFixit !! I wanted to know if you notice any upgrades on the back cameras, particularly on the stabilization?? Being and iPhone user and motorcycle rider don’t go hand in hand with iPhone 11 .

When will we see a component swap test? So far it looks like we cant even swap the camera module without it going wonky, can you test if the displays can be swapped and other components?

The Stem - 回复

I really think it deserves a lower repairability score. Sure, most things are modular, but with the 12 series Apple has paired most important components to each logic board. These components either lose functionality or flash a message that the components aren’t original. Now added to this list with the 12 is the camera which, you guessed it, is now paired to each iPhone. This is a massive F You to many independent repair shops because now you can’t replace the battery without losing many major features. Even with genuine original parts and pairing serial numbers makes no difference. It seems like the amount of parts paired increase with each generation of iPhone, and it’s only going to get larger. We as consumers cannot repair the phone that we own, so do we really own the phone? With all of this said, I think the phone deserves a four at most. I mean I don’t work at ifixit so this is just a suggestion, but with all of this new BS we shouldn’t give Apple any benefit of the doubt.

CW Seely - 回复

On your 11 Pro Max teardown (and maybe on the smaller Pro teardown as well) you gave us thickness (4.6mm), volume (23.8 cubic centimetres) and weight (59.6g) numbers for the internal battery. I’d be really interested in seeing those three numbers for the 12 Pro battery and, when you do the teardown for the 12 Pro Max, for that battery as well. Thanks.

Sergej Rogowski - 回复

Apple is pairing parts with the phone by proprietary software which basically makes it un-repairable. If you switch something out and don’t pair it correctly the phone will bug out.

Per Weum - 回复

I guess you will have to correct the repairability score to 0 if it is confirmed that replacing parts even with original and genuine i-phone 12 parts causes many artificially created issues with the camera, face id and the battery… Check this great video by Hugh Jeffreys!

If I’d read-on before my comment at the top (first opportunity) of this page, I would’ve seen your mention of the ‘huge asterisk’ and link to (I’m assuming here) the explanation of that asterisk. With the components being somehow ID’d to eachother and the logic board, and no instructions how to reestablish full functionality of All features AFTER a replacement of any component/module, how is this a 6?! It’s a ZERO. Maybe a one, since you can perform the mechanical operations related to Hardware repair/replace. Bud certainly, if you’re left with less than 99% (waterproofing may not be achievable?) of a repaired device, this doesn’t seem like even a 6…
