Iphone 11 Pro Max Teardown: Smaller Motherboard Bigger Battery And Snowed-in Eggs


[Bestbuy618 mobile channel] The iPhone 11 series has been officially released, and many partners should have received their favorite products, but I believe there are still some mysteries in your mind that have not been resolved: for example, how big is the battery and memory of the new iPhone? Signal problems have not been resolved? The following let us through iFixit brought the iPhone 11 Pro Max disassembly, to find the answer it. Other features include Gigabit LTE, Wi-Fi 6, Bluetooth 5.0, NFC, and IP68 level dust and water resistance (up to 30 minutes underwater at a depth of 4 meters), wireless charging, and fast charging.

The iPhone XR, iPhone XS Max, and iPhone 11 Pro Max are three products that highlight the changes in the design of the back of the latest generation of iPhones, including the frosted back case, the bath triple camera, and the shifted Apple logo. Based on my firsthand experience, the new iPhone feels far superior to previous generations of products. The new iPhone is an excellent addition to the iPhone 11.

As seen in the X-ray images, the iPhone 11 Pro Max has a smaller motherboard, which iFixit claims allows for the rear triple camera. At the same time, the battery is different from the iPhone XS Max, not two pieces spliced together, but a whole block; the wireless charging coil under the battery also appears to have changed, which we will further reveal in the subsequent teardown. Through the camera close-up, the iPhone 11 Pro Max appears to have a less pronounced camera bulge when compared to the iPhone XS Max.

As always, the first step is to remove the two screws at the bottom of the iPhone 11 Pro Max body, after which you can pry the screen off the phone using suction cups and warp plates. Although Apple claims that the iPhone 11 Pro Max’s waterproof performance is the strongest yet, iFixit claims that the screen edge of the adhesive, fixed screw washers is similar to last year’s phone.

After separating the display from the motherboard’s cables, you can see what’s inside the phone, and the large battery is undoubtedly the most eye-catching feature. iFixit discovered two cables on the battery. There are likely many reasons why Apple chose this design, but “bi-directional charging” is most likely one of them.

Remove the battery first, followed by the rear camera and front camera modules from the iPhone 11 Pro Max. While the rear camera is one of the most significant upgrades to the new iPhone, bringing an ultra-wide angle lens, you may have missed the fact that Apple has quietly upgraded the front camera from 7 to 12 megapixels.

Meanwhile, iFixit notes that the Face ID module on the iPhone 11 Pro Max has undergone some changes, with the cable no longer being pressed beneath the battery, making it easier to disassemble. The iPhone 11 Pro Max rear triple camera has been introduced above, and in addition to the three cameras in this “bathrobe combination,” it also includes a flash and a microphone.

iFixit discovered that, despite the fact that the iPhone 11 Pro Max’s three rear cameras are held together, each has its own cable, and X-ray photos show that two of them – the wide-angle camera and the telephoto camera – support OIS optical stabilization. Remove the isolation cover above the motherboard in turn, and then remove the motherboard. The motherboard of the iPhone 11 Pro Max is clearly smaller than that of the iPhone XS (which has been changed from L-shaped to rectangular), but identical to that of the iPhone 11 Pro.

The next step is to separate the small, double-layered motherboard, a process that requires heating to separate the connecting posts. The fixed components on the motherboard are shown below, the red box for Apple APL1W85 A13 bionic chip, as well as SK Hynix LPDDR4X memory (from previous exposure information, the iPhone 11 series all use 4GB memory); orange box for Apple APL1092 343S00355 PMIC; yellow box for Cirrus Logic 338S00509 audio codec; green box for the possible U1 ultra-wideband chip; and cyan box for

The Apple/USI 339S00648 WiFi/Bluetooth SoC is located on the corresponding other side of the motherboard in the red box; the Intel X927YD2Q modem is located in the orange box; the Intel 5765 P10 A15 08B13 H1925 transceiver is located in the yellow box; the Skyworks 78223-17 PAM is located in the green box; the Skyworks 13797-19 DRx is located in the blue box; Apple previously white oh is the iPhone 11 Pro series heat dissipation has been improved, with heat from the motherboard being transferred out through multiple layers of graphite by the back shell. Although Apple’s design does not appear to be as cool as the “liquid cooling” used in Android phones, iFixit claims that the effect of this cooling design is more satisfactory while not interfering with signal transmission.

The iPhone 11 Pro Max has a 15.04Wh (3969mAh, 3.79V) battery, which is 2.96Wh more than the iPhone XS Max’s (and weighs 13g more) and 1.52Wh less than the Samsung Galaxy Note 10 5G battery. iFixit disassembled this daughter board further and discovered the following chips on it: ST Microelectronics STPMB0 929AGK HQHQ96 153915, Apple 338S00411 audio amplifier, and TI 97A8R78 SN261140 A0N0T. The iPhone 11 Pro Max can support bi-directional wireless charging, but Apple did not open it up, but snowed it away.

So two-way (or reverse) wireless charging could be the egg of the iPhone 11 Pro Max; however, it is unclear whether Apple will subsequently enable the function via a firmware update. Previously, some sources stated that Apple’s official announcement of the design could be the reason that charging efficiency does not meet the requirements.

According to iFixit, the bottom component of the phone is more securely fixed than last year, allowing it to support a better waterproof design. Next, the iPhone 11 Pro Max’s display module is disassembled. According to iFixit, the display module is about a quarter of a millimeter thinner than its predecessor due to the removal of 3D Touch, and this space appears to be occupied by the battery.

There is also a chip “S2D0S23 G1927K3Q 608HVG” on the back of the display module.

The iPhone 11 Pro Max’s family photo is shown below. The phone has a larger battery, according to iFixit, and while it’s unclear how Apple will handle “bi-directional charging,” the new design is good for better battery life management. The iPhone 11 Pro Max’s final iFixit repairable score is 6 out of 10, with the higher the score, the easier it is to fix. The battery and display are relatively simple to disassemble and repair, and many components are modular and can be replaced separately.

Furthermore, although Apple replaced some of the adhesives with screws, the iPhone 11 Pro Max in not just a screw, but also need to disassemble when the tools are ready to complete, in addition, despite the improved waterproof to disassembly brought some difficulties, but at the same time this also reduces the risk of the phone into the water Sun Wah. The most difficult part of replacing the iPhone 11 Pro Max is still the glass panel, particularly the glass back of the phone, which, once damaged, requires the phone to be completely disassembled before it can be replaced.
