After disassembling the smart speaker HomePod, Samsung's Galaxy S9 and 2018 iPad Pro, the famous dismantling agency iFixit extended the "claw" to the Huawei P20 Pro equipped with "Leica III" on the back. Let's take a look at the related content with the mobile phone portable Xiaobian.
Yes, Huawei P20 Pro is undoubtedly one of the hottest star models recently. Whether it is the appearance of “Liu Haier†with Home button, or the design of back gradient and “Leica three photosâ€, it makes a lot of People are impressed with Huawei's flagship of this P series this year. Among them, the "Leica three-shot" lens led by the 40-megapixel main camera on the back makes the Huawei P20 Pro the first place on the DxOMark leaderboard. Therefore, many people may wish to know what is unique about the internal structure of this mobile phone that is bold and novel in camera design.
Below, we will follow the iFixit perspective to get a deeper understanding of this flagship. Huawei P20 Pro basic configuration:
Screen: 6.1-inch OLED full screen
Core: Hays Kirin 970
Stock: 6GB
Storage: 64GB / 128GB / 256GB
Front: 24 million pixels (F/2.0)
Rear: 40 megapixels (main camera, F/1.8) / 20 megapixels (black and white, F/1.6) / 8 megapixels (telephoto, F/2.4)
Battery: 4000mAh
System: EMUI 8.1 (based on Android 8.1 Oreo)
Other: IP67 waterproof and dustproof / face recognition / fingerprint recognition / Super Charge fast charge
The 3 cameras on the back have optical image stabilization. Although the Huawei P20 Pro is a mobile phone that supports IP67 protection, this does not make the whole process of disassembly difficult. Instead, the iFixit team eliminated the need for a heated lid to open the lid of the P20 Pro with a single suction cup tool and paddle.
After unscrewing the screws, unscrewing the cable, and disassembling the backplane, we were able to see the board with the "Leica III" and the flash. It can be seen that the three rear cameras and the flash are designed as one module and are arranged quite compactly.
Although this is a "Leica three-shot" lens module, Huawei only designed two cables for it. The 40-megapixel main camera and the 20-megapixel black-and-white camera share one cable, and the other 8 million. The telephoto camera of the pixel has another cable.
From the side, the right-most telephoto camera has a raised height. The 40-megapixel main camera uses a 1/1.7-inch sensor, which is 1/2.9-inch sensor on the iPhone X and the Samsung Galaxy S9+. The 1/2.55-inch sensor is even larger, with an ISO of up to 102,400. More importantly, iFixit found through disassembly that both the 40-megapixel color camera and the black-and-white camera that looks "flat" have OIS optical image stabilization.
iFixit uses dice to demonstrate that the three cameras support optical image stabilization. That is to say, the three cameras on the back seem to have OIS optical image stabilization on the hardware level. Obviously, this is in line with Huawei's announcement at the press conference that only the 8 megapixel telephoto camera is equipped with OIS optical image stabilization, and the other two cameras are based on the artificial intelligence chip to achieve AI image stabilization, there is a certain discrepancy.
However, Huawei has not commented on this yet, and we still don't know how these three cameras with optical image stabilization work. In fact, in addition to the three cameras with optical image stabilization, iFixit also noticed a detail. The board carrying the camera module is also connected to a sensor for laser focusing on the back cover, so that Huawei P20 Pro can be realized. Fast focus.
The Huawei P20 Pro's 40-megapixel camera hides a Nokia team six years ago. Search WeChat public number Love Fan, back in the background "P20", see more. Modular component design and large-capacity battery The modular design of the components inside the Huawei P20 Pro was deeply impressed during the entire disassembly process. For example, the camera modules described above, the boards carrying them, the small motherboards equipped with the Kirin 970, the vibration motors, and the type-c charging interface are all modular in design. The advantage of this is that once these parts are damaged, it is easy to repair by simply replacing them.
We briefly put the focus on that small motherboard, which integrates important components such as the Kirin 970 core, the magnesium 6GB LPDDR4, the Samsung 128 GB flash memory, and NXP's NFC controller.
Below is a list of specific parts on the motherboard:
Magnesium 6 GB LPDDR4 SDRAM packaged in the Kirin 970 chip
Samsung KLUDG4U1EA-B0C1 128 GB V-NAND Flash
Haisi Hi6403-GWCV110 Audio IC
Texas Instruments BQ25895 I2C Charge Control Module
NXP 55102 PN548 NFC Controller
HiSili Hi6363-GFCV100 RF Transceiver Module
Skyworks 78113-14, 78114-61 and 78117-4A Skyone front-end LTE module
Haisi Hi6421-GFCV810 Power Management IC
Cypress BCM43596 Wi-Fi and Bluetooth Module
Haisi Hi6423-GWCV100 Power Management IC
Huawei P20 Pro In addition to the easy replacement of some modular components, the battery is easier to disassemble than most mobile phones.
During the disassembly process, iFixit found that the battery of Huawei P20 Pro was not fixed with a lot of sticky glue. Therefore, disassembling the battery does not require heating with a hot air blower. It is easy to use the battery with a little sol. take out. In other words, this battery is similar to the previous Huawei Mate 10 Pro battery. It is rated at 3.82 V and has a battery capacity of 4000 mAh (equivalent to 15.28 Wh).
This battery specification far exceeds the Samsung Galaxy S9+ 13.48 Wh and iPhone X's 10.35 Wh parameters, which is helpful for improving the battery life. Huawei P20 Pro is more difficult to repair than the iPhone X. Although the Huawei P20 Pro has a modular design on the internal parts, it is relatively easy to replace parts, but the iFixit team still believes that the Huawei P20 Pro is less repairable and gives it a shot. A 4 point "maintenance" rating (a total of 10 points, the higher the score, the easier it is to repair).
This score is comparable to the Samsung Galaxy S9/S9+, but is lower than the 6 points scored by the iPhone X. In the view of iFixit, the deduction point of Huawei P20 Pro is largely deducted from the screen. In order to remove the P20 Pro's screen, iFixit needs to use an iOpener heating pillow to heat the screen so that the glue between the screen and the middle frame melts.
Of course, this is just a challenge when replacing the screen assembly. If the screen is broken, it will be more troublesome to disassemble. You need to use heating again to separate the inner and outer screens. Such a separation operation easily causes damage to the glass panel.
Because of this, when you only need to replace the distance sensor, light sensor, front camera and earpiece, you need to overcome the problems encountered when disassembling the screen assembly. In addition, the back cover of the glass is easy to remove, but such a material also increases the possibility of damage to the back cover. In general, iFixit considers the Huawei P20 Pro to be less repairable. From a maintenance point of view, the advantages of the Huawei P20 Pro are:
Many components are modular in design for easy replacement
It is not too difficult to replace the battery, it takes some time and effort.
The disadvantage is:
The front and rear glass design of the mobile phone increases the risk of breakage during disassembly
When replacing the screen, at least two times against the strong glue, it is not easy to remove it.
The above is about mobile phone portable - the world's first real machine dismantling! Huawei P20 Pro real machine dismantling related introduction, if you want to know more information, please pay attention to eeworld, eeworld electronic engineering will provide you with more complete, more detailed, updated information.
Lithium-boron alloy is a composite material composed of a brittle Li7B6 matrix phase with a porous structure and a ductile Li filling phase. The density is 0.88±0.04g/cm3. The appearance is silver-white metal. It is extremely unstable. It is easily deteriorated when exposed to air and reacts with water. severe. Lithium-boron alloy is mainly used as anode material for lithium-based thermal batteries. It has outstanding advantages such as high specific energy, high specific power and low polarization, electrochemical potential similar to that of pure lithium, and solid state above 600℃. It is a new type of lithium-based thermal battery. The excellent negative electrode material. Compared with the currently widely used Lithium-Silicon Alloy, the unit cell assembled with the lithium-boron alloy as the negative electrode material has better performance in both the highest voltage and the discharge working time.
