Today, we continue our in-depth look at the iPhone 8 Plus disassembly report, which is the second of three iPhones released by Apple earlier this month. Join us as we follow iFixit to explore the internal structure of the iPhone 8 Plus and discover what makes it tick.
1.
Let’s start with a quick recap of the main specs of the iPhone 8 Plus:
- It features a new A11 Bionic chip paired with the M11 motion coprocessor.
- It offers 64GB or 256GB of onboard storage.
- The 5.5-inch Retina HD display has a resolution of 1920 × 1080 pixels (401 ppi).
- The dual 12MP camera system includes f/1.8 wide-angle and f/2.8 telephoto lenses with optical image stabilization, 10x digital zoom, and portrait mode effects.
- The front-facing FaceTime HD camera is 7MP with f/2.2 aperture and supports 1080p video recording.
- It supports fast charging and Qi wireless charging.
- Connectivity options include dual-band Wi-Fi, Bluetooth 5.0, NFC, and MIMO technology.

In terms of design, the glass back shell of the iPhone 8 series remains eye-catching. The front and rear double-glass design is reminiscent of the classic iPhone 4 and 4s, while the overall shape follows the iPhone 6 Plus design. The most significant change is the support for wireless charging. Additionally, the machine model and inspection marks that were visible on previous models are no longer present, though the model number A1864 can still be found on the packaging.

Before disassembling, an X-ray scan reveals the prominent wireless charging coil inside the device.
4.
During screen removal, iFixit noticed that the screw positions were slightly deeper than before, and the indentations were slightly larger compared to previous models.
5.
The screws securing the battery cable are standard #000 Phillips screws. The tape used to secure the battery is similar to the iPhone 8 but includes two additional strips compared to the iPhone 7.
6.
The battery has a capacity of 2691 mAh at 3.82V, providing 10.28Wh of power. While slightly smaller than the iPhone 7 Plus's 2900 mAh, Apple claims performance is comparable or better, especially with fast charging support.
7.
Removing the battery required peeling off three tapes, and the original battery tape was increased to four to prevent the battery from sticking to the middle charging coil.
8.
The logic board uses standard screws and Phillips screws, similar to previous models.
9.
On the logic board, you’ll find components such as the A11 Bionic CPU, Qualcomm LTE module, Skyworks RF components, Avago ICs, and more.
10.
The back of the logic board houses the Wi-Fi/Bluetooth module, PMIC, NAND flash, and various RF components.
11.
After removing the logic board, the speaker and Taptic Engine are exposed, revealing the sound hole and internal structure.
12.
The sound ring sealing ring and Lightning interface are designed similarly to the iPhone 8, with a focus on wireless charging efficiency and heat dissipation.
13.
Following lessons from the iPhone 8, iFixit heated the glass backplate, but it proved challenging. If damaged, the glass may require replacing the entire back frame, making a protective case essential.
14.
In conclusion, iFixit gave the iPhone 8 Plus a repairability score of 6 out of 10. While the screen and battery are easy to replace, waterproof seals and complex internal structures make repairs difficult. The glass backplate is durable but hard to replace if broken. Overall, it's a solid upgrade with improved performance and features.
