Before disassembly, always obtain and consult a detailed schematic diagram showing internal component placement.We benefit from a close working relationship with Creative Electron, a supplier of X-ray equipment.
While the overall design echoes previous iPhone 12 models, a notable difference lies in the dark steel construction of the frame.This task requires specialized expertise and should only be performed by a qualified technician.The magnetic attachment area, previously appearing small on the 12 mini model, now seems disproportionately small when compared to the larger dimensions of the Max.
The iPhone Max retains the larger, L-shaped battery design—a feature notably absent from the Pro model—which is of particular interest for evaluation, contrasting with the standard rectangular battery found in other iPhone variants.

Proceed immediately with the next step, as delays will impact the project timeline and subsequent disassembly tasks.
  • Begin the repair by focusing on the Pro Max model's advanced camera system.
  • The 12 Pro Max's improved audio performance originates from the wide-angle camera, located bottom left among the three lenses, which incorporates a sensor 47% larger than previous models to enhance light capture and photographic quality.
  • Examination using X-ray technology reveals the standard wide lens's sensor is larger than expected, and four magnets positioned around it indicate the presence of Apple's new sensor-shift image stabilization system.
  • For a detailed explanation of the LIDAR system's functionality, refer to the accompanying video tutorial.

The main camera's image sensor within the iPhone 12 Pro Max is notably sizable, mirroring the device's overall dimensions.
  • Due to space limitations within the iPhone 12 Pro's internal design, integrating this component—typically found exclusively in higher-priced models—would likely necessitate design alterations or compromises.
  • Despite maintaining a 12 MP resolution, the sensor's physical size is 47% greater than that of an iPhone 12, resulting in individually larger pixels for enhanced light capture.
  • The sensor incorporates sensor-shift image stabilization technology, a feature that allows for image stabilization by physically moving the sensor.

Using the specialized tools included in the Minnow Driver Kit, you can easily detach the loudspeaker and Taptic Engine.
  • To participate in our Minnow giveaway, carefully examine the teardown images and identify the two steps that were captured using an iPhone and the Halide camera application.
  • The Max Taptic Engine incorporates a small, black plastic component, functionally acting as either display support or a battery buffer. While appearing to occupy otherwise empty volume within the iPhone, this design element isn’t entirely uncommon.
  • To accommodate the larger Taptic Engine and speaker, Apple prioritized these components over battery capacity, resulting in a notably smaller battery compared to the mini model.

  • Despite the "L" designation, the iPhone 12 Max utilizes the highest-capacity battery among all iPhone 12 models, distinguished by both power and innovative design; internal analysis reveals the battery occupies nearly the maximum available space within the device's enclosure, owing to its uniquely contoured form that maximizes volume.
  • With a weight of 14.13 Wh, the Max power source is heavier than both the 8.57 Wh mini battery and the 10.78 Wh batteries found in the 12 and 12 Pro models.
  • The battery capacity is reduced compared to the 15.04 Wh found in the iPhone 11 Pro Max, and is smaller than those in the Galaxy Note 20 (16.69 Wh) and Galaxy Note 20 Ultra (17.46 Wh).

Having removed the logic board from the Pro Max, its size is surprisingly close to that of the iPhone 12 mini’s, although the mini’s integrated SIM reader presents a design constraint that affects its overall dimensions.
  • Similar to the 12 and 12 Pro models, the 12 Pro Max incorporates a separate, modular SIM reader assembly designed to simplify repair procedures.
Before disassembly, observe the entire circuit board to appreciate its complex, multi-layered construction; the arrangement of silicon components resembles a miniature, highly detailed urban landscape.

With viewer support, the complete disassembly of the fourth-generation iPhone for this season is now complete, and downloadable wallpapers are available.
This year's Pro Max model represents Apple's most advanced iPhone, incorporating sophisticated 5G technology without sacrificing performance in other areas.
The iPhone still utilizes its distinctive L-shaped battery design, a feature we anticipate may reappear across the entire iPhone product range in the future, as larger battery capacities often correlate with extended operational lifespans and reduced replacement frequency.
As a demonstration of the camera's enhanced features, two sample images captured using an iPhone are provided for your review, located at the specified links. We extend our congratulations to the individuals who accurately predicted this outcome.
The camera module on our test iPhone 12 Pro Max functioned without issue, a contrast to the problems encountered with the standard iPhone 12 during the same repair procedures; we trust this difference represents an isolated anomaly.
