This week's news about the iPhone XR is quite a lot. Ai Faner also experienced the iPhone XR from the external design and intrinsic performance. Even the meaning of XR's "R" is discussed. However, I have seen a few tangible places in design, performance, experience, etc. Now let's take a look at iFixit's disassembly of iPhone XR. We can get some very interesting information by disassembling.

The iPhone XR is the disappearing iPhone 9.

After dissolving the iPhone XR, iFixit concludes this way.

Before disassembling, let's review the configuration of the iPhone XR:

  • Processor: A12 Bionic chip and Neural Engine neural network engine
  • 6. 1" Liquid LCD display, 1792× 828 resolution, support for original color display and P3 color gamut
  • 12 megapixel rear single shot. f/1.8 aperture with OIS optical image stabilization, 7 megapixel front, support for Face ID
  • 64G/128G/256G onboard storage
  • Support e-sim and many frequency bands, support Bluetooth 5.0 and NFC
  • IP 67 waterproof

Ok, let's get started, this time iFixit brings a disassembly of the blue iPhone XR.

data-pre-sourced=yes

In order to better see what choices XR has, iFixit also found an iPhone XS for a simple comparison. You can see some obvious differences. For example, the XR does not have an antenna break at the bottom of the iPhone XS. The symmetrical bottom makes it more like the iPhone X that Apple released last year, but at the same time XR does not have the Gigabit LTE support of XS.

The fact that everyone on earth knows: the iPhone XR has a thicker border. iFixit has released a macro comparison chart. From this picture we can carefully observe how much the difference between the two borders is.

This picture shows another big difference. The iPhone XR's rear camera is single shot, while the iPhone XS is dual shot. Although the main camera is the same, the XR lacks a telephoto end, which means that the double zoom can only be done with digital zoom, and the viewfinder is wider when using portrait mode.

data-pre-sourced=yes

Remove the screw and then suck the screen up. This is similar to the disassembly of the iPhone XS, but the XR's SIM card slot is closer to the bottom. The iPhone XR after picking up the screen actually looks like a mix of iPhone 8 and iPhone X, you can see the returning rectangular battery, and the same rectangular motherboard. Now the question is coming. How many layers does the XR motherboard have?

data-pre-sourced=yes

iFixit encountered a lot of fixing screws during the disassembly of the motherboard, but also found many surprises, such as the SIM card slot became modular on the iPhone for the first time, which means that XR can quickly replace the broken SIM card slot, and It can also reduce the cost of the motherboard. In addition, unlike the dual-layer motherboards of the iPhone X and XS series, the XR uses a single-layer motherboard design.

data-pre-sourced=yes

Now let's see what's on the motherboard:

  • Red: A12 Bionic processor
  • Orange: Apple/USI 339S00580 may be WiFi/Bluetooth module
  • Yellow: NXP 100VB27 NFC chip
  • Green: 3 Apple 338S00411 audio amplifiers
  • Blue: Skyworks 203-15 G67407 1838 may be a power amplifier module
  • Twilight: Cypress CPD2 USB Power IC
  • Purple: 76018 119G1

data-pre-sourced=yes

The integration is too high and it is difficult to finish it at one time. See the picture to continue:

  • Red: Toshiba 64GB flash
  • Orange: Intel XMM7560 4G LTE baseband
  • Yellow: Apple's power management chip
  • Green: Texas Instruments SN2600B1 battery charging chip
  • Blue: Apple 338S00248 audio codec
  • Twilight: Skyworks 13768 front-end module
  • Purple: Broadcom 59355A2IUB4G, may be a wireless charging receiver chip

data-pre-sourced=yes

There are so many things on the motherboard. The iPhone XR's motherboard is very interesting. The iFixit said that the iPhone XR is the iPhone 9 that disappeared. In fact, this motherboard also fills the gap between the iPhone 8 Plus and the iPhone X. . This picture shows a comparison of the iPhone 8 Plus, iPhone XR and iPhone X motherboards. The 8 Plus motherboard is larger and has a bent design, while the XR is like an iPhone X motherboard.

data-pre-sourced=yes

After removing the motherboard, the Taptic Engine linear vibration motor can now be removed because the 3D Touch is removed on the iPhone XR and replaced by a long press + Haptic Touch with tactile feedback.

data-pre-sourced=yes

The boxy battery was easy to remove because iFixit found four complete adhesive tabs. Compared to the iPhone 8 Plus, the XR's battery looks smaller, but it's deceptive because the iPhone XR's battery is actually thicker.

The iPhone XR has a battery capacity of 2946mAh (11.16Wh), which is larger than the iPhone XS's 2658mAh (10.13Wh), and the iPhone XR has even better endurance than the iPhone XS Max and iPhone 8 Plus.

data-pre-sourced=yes

The XR uses the same wide-angle camera as the XS and XS Max. Although it is only single-shot, it performs quite well in the physical camera test of Ai Faner, which is equivalent to the XS series. There is also the original deep sensor module for Face ID.

The iPhone XR's screen is bigger, thicker and heavier than the iPhone XS's screen, and requires a backlight module. As we have seen before, the LCD's disadvantages over AMOELD are fully reflected in the XR. Moreover, the thicker LCD screen module causes the lighting interface on the bottom and the speakers on both sides not to be in a straight line.

data-pre-sourced=yes

The iPhone XR's wireless charging coil uses a copper coil that is lower in resistance than the iPhone X, so the theoretical heat is even smaller.

data-pre-sourced=yes

Finally, iFfixit gave iPhone XR a maintainable score of 6 (the higher the score, the easier it is to fix, out of 10)

iFixit concludes that the design of the iPhone is very much like the combination of the iPhone X and iPhone 8 series, like a rectangular battery and a single-layer motherboard that gives it the feel of the iPhone 8, but without the curved rectangular board and the Face ID let it look There are a lot of elements on the iPhone X, and although the name is different, the iPhone XR is actually the "spirit iPhone 9". But XR is not a complete return, it also includes the latest A12 chip and new features, as well as a new design of modular SIM card slot.

If you are interested in iPhone XR or are unclear about the features, then you can look back on the iPhone XR that Ai Fan had a few days ago.Evaluation.
