During the National Day holiday, Google Pixel 2/2 XL was released, the second generation of "Huang Prince", "Da Xiu Muscle", such as a single camera rolling double-time, etc. Like a lot of flagship models released this year, Google is equipped with a full screen design for the size of Pixel 2 XL, and "white plus black" coloring body has also won the "Panda Machine" nickname.
First briefly introduce the configuration information of Pixel 2 XL, which is equipped with a resolution of 2880x1440 (6.0-inch OLED screen for 538 PPI (Pixel 2 uses a 5.0-inch OLED screen, the resolution is 1920 × 1080), the screen ratio is 18 : 9 It seems to be thin. At the same time, the fifth-generation gorilla glass (Gorilla Glass 5) above the mobile phone screen guarantees strength and scratching.
Pixel 2/2 XL is equipped with Qualcomm Snapdragon 835 processor, equipped with 4GB LPDDR4 memory with a storage space of 64GB or 128GB. The camera configuration of the two mobile phones is also the same, 8 megapixels, F / 2.4, unit pixel size 1.4μm; the rear camera is 1.42 million pixels, F / 1.8, unit pixel size 1.4μm, support optical anti-shake, double-pixel Phase Detection Autofocus and laser detection autofocus.
In addition, Pixel 2/2 XL supports IP67 waterproof and dustproof, edge pressure sensing, and the Android 8.0 OREO system. Battery, Pixel 2 XL battery capacity is 3250mAh (Pixel 2 is 2700mAh), supports 18W fast charge, fingerprint identification is located on the back of the phone.
Next, "routine X-ray check" is made for Pixel 2 XL.
The red box in the picture is also its pressure sensor to support edge compactive operation. The orange square is a vibrator; although the naked eye is unable to distinguish, the Pixel 2 XL mobile phone is returned to the antenna, and the area in the yellow box is shown in the image.
Compare Pixel 2 XL and iPhone 7 Plus, it seems that the former looks more distinctive ... iPhone is too easy to have aesthetic fatigue!
The significant difference between PIXEL 2 XL and PIXEL 2 is the body size, of course, a better screen can be obtained by Pixel 2 XL users.
The following starts to disassemble, Pixel 2 XL supports IP67 dust-proof waterproof, so it is necessary to do some homework in the body's hatter, and is equipped with a gasket for this Pixel 2 XL SIM card. Of course, as a highlight of Pixel 2 XL, this device also supports ESIM. Embedded universal integrated circuit card (ESU / Embedded SIM) or an embedded general integrated circuit card (EUICC), the size of this product is smaller than the NANO SIM card we generally adopted, and directly welded during manufacturing On the motherboard of the device.
Next, "Pixel 2 XL, with the previously disassembled iPhone 8/8 Plus, Samsung Galaxy Note 8, Essential Phone and other mobile phones, Pixel 2 XL is more" easy to start ", do not need heating, with suction cups and leathers Yes.
Like other products, the display module is connected to the motherboard through a set of cables. However, Pixel 2 XL cable wants ... Long! No matter what, dismantling this step needs to be careful, and an extensive fierce consequence may be "machine destruction".
Similar to Pixel XL, the Pixel 2 XL screen is equipped with magnesium box (the anti-roller used in the notebook), increasing the stability of the internal structure of the body, when an accident occurs (such as screen squeezing) Protect the motherboard and battery and other components.
After taking the frame in the metal, you can see the battery, motherboard, as well as a metal thermal conductive tube located on the other side of the frame, which will facilitate the performance of the "liberation" mobile phone and improve heat dissipation efficiency.
Next, dismantle the battery, first disconnect the cable connection. According to IFIXIT, the Pixel XL of HTC OEM last year has an "strap" that can easily pull the battery.
But this year's LG did not join a similar design, so the process of removing the battery is needed ... Slowly come!
Pixel 2 XL is equipped with a 13.6 WH (3.85 V, 3520 MAH) battery, slightly higher than last year's 13.28 WH, and Samsung Galaxy S8 + (13.48 WH) is similar, and the iPhone 8 Plus (10.28 WH) is far behind.
Below is the very important advantage of Pixel 2 XL - camera! Confirmed the most authoritative third-party testing institutions DXOMARK to play 98 points for Pixel 2 (the highest mobile phone so far), however, pay attention to Yes, although Pixel 2's comprehensive score (weighted tap, video performance) is the highest, but in the photo part, it is slightly in the Samsung Note8, the latter is 100 points at this project.
The copper foil flashed on the camera will be opened, and the Pixel 2 XL main camera pixel is 1.22 million, close to the first generation of products (12.3 million), but this year Google has added a double-pixel sensor for the mobile phone, optical anti-shake function, and The aperture is upgraded from last year's F / 2.0 to f / 1.8.
Next front camera disconnect connector with the motherboard, a number of fixing screws removed, then the motherboard will be able to out slowly.
The front camera can naturally be separated, the Pixel 2 XL front camera is 8 million pixels, due to the new iPhone's 7 megapixel front camera.
The front camera can naturally be separated, the Pixel 2 XL front camera is 8 million pixels, due to the new iPhone's 7 megapixel front camera.
Here, the motherboard on the main board is introduced:
In the red box, Samsung K3uh5H5 4GB LPDDR4 memory, and Qualcomm Snapdragon 835;
The orange square is Samsung Klucg4j1ed 64GB universal flash.
The yellow box is Avago AfEM-9046 KA1717 LB003 172604S6 00105;
In the green box to Qorvo QM78035 (probably RF Fusion module?);
The cyan square is Skyworks 7360-2a 1716 HX;
In the blue box, NXP 81A04 39 04 SSD730 (probably an NFC controller) and Murata SS7715005 (WiFi / Bluetooth module?);
In the pink box, it is the first mobile chip Pixel Visual Core (labeled SR3HX X726C502), which can accelerate the processing speed of HDR + photo, further enhance Pixel 2 XL camera performance.
From the layout map published by Google, Pixel Visual Core is similar to the past eight-core processors, but strictly speaking, the Pixel Visual Core has 9 processing cores, including 8 separate IPUs and an ARM Cortex-A53 core. These 8 independent IPUs are designed to improve HDR + 5 times performance in order to handle HDR + tasks.
Google said that in the next few weeks, Pixel Visual Core will be released together with the Android 8.1 developer preview. After the Pixel Visual Core is activated, the third party APP will also use the HDR + image processing function of PIXEL 2.
On the other side of the motherboard:
In the red box, ST microelectronics ST33G1M2, 32-bit MCUs of ARM SecurCore SC300 (like embedded SIM cards found in Apple Watch Series 3);
The orange square is high-pass WTR5975 Gigabit LTE radio frequency transceiver;
The yellow box is high-pass PM8998 power management integrated circuit;
In the green box, it is PMI8998 003 7R71286 HE720 13 (may come from Qualcomm?);
Cyan block the fourth-generation high-pass SMB1381 fast charging module;
The blue box is within the pink box for Ti 75AQJH1 2557 (possibly from Texas Instruments).
Next, the processing modules on the phone number of the border, such as a volume key, a power key, can be seen by disassembling the two parts are "integrated" in a plastic frame.
Then the speaker assembly at the bottom of the phone.
There are multiple sets of sensors in the circuit, and IFIXIT speculates that these sensors consist of deformation sensitive resistors, change their resistance during extrusion, stretching, thereby implementing control.
It is then a sensor that supports edge pressure operation. The sensor is placed in a metal groove on the inner side of the metal, and is connected to a flexible printed circuit board, symmetrical arrangement on the lower end of the mobile phone.
Pixel 2 XL uses both sides of symmetrical sensor design to effectively improve the sensitivity of distinguishing pressure, and achieve more precise feedback for the user's operation. The previously released HTC U11 supports this feature, and the user can design the pressure response level.
Here is the TYPE-C port assembly of your phone. Pixel 2 XL is the same as a lot of smartphones, and also canceled a 3.5mm headphone interface, so the frequency of use of Type-C charge will increase, and the possibility of wear is also higher, so many smartphones will be partially used as a separate module. easy to replace, repair, which is one of 2 XL Pixel.
The fingerprint sensor is designed and clean and profitable.
The Pixel 2 XL fuselage has a two-stage design, which is a glass material, which facilitates the improvement of the transmittance of the antenna to ensure the phone signal. However, it also adds some difficulty to dismantling, and it is necessary to heat the softening adhesive to remove it through the crowns.
The dismantling of the back glass material can only start from the outside of the mobile phone, and there is an antenna under the outside of it.
The remaining components of the top of the fuselage need to be heated to separate: mobile phone handset and NFC antenna.
Finally, look at the family blessing of Pixel 2 XL!
