Appearance and workmanship
In addition to the conventional instructions, pins, chargers and power cords, the accessories of Huawei G9 Youth Edition also include earphones that are rare in domestic computers.
The earphone is similar to Apple EarPods in opening and appearance, and supports remote control. The output of the charger is only 5V1A, so it is necessary to cope with the pressure of 3000mAh battery proposal It is equipped with a 5V2A charger.
There are gold stripes under the glass cover of the front forehead and chin. The forehead is a front camera, and the distance and light sensor and receiver are parallel up and down. There is only one logo on the chin.
The back cover is made of plastic material with horizontal wire drawing lines, and the top camera part is a smooth cover. A circle of silver edge decoration is rarely added around the fingerprint identification module.
The top is a noise reducing microphone and headphone connector, the headphone connector also has an antenna slot, and the bottom left side is a symmetrical microphone and speaker opening.
The frame of the fuselage is made of metal, and there are bright chamfers on the upper and lower sides. The signal slot is an independent plastic part instead of a common injection molding.
The volume and power buttons are on the right, and the power button has twills for easy identification. The key design has a large void. Fortunately, the key rebounds easily and feels good when pressed.
There is only a sim card slot on the left, the classic "and or card slot". Insert two nano sim cards or sim cards+TF cards at the same time. The workmanship of the card slot is better, the combination is tight, and the virtual position is very small.
The joint between the frame and the back cover does not show the corner of the hand, and the overall feel is good.

Screen objective test results
The machine is equipped with a 5.2 inch 1080P IPS screen and dual domain pixel technology that can improve the visual angle. The official NTSC color gamut is up to 85% (71% for iPhone).
In the default mode, the measured maximum brightness is 493 nits, the contrast is 1254, and the color temperature under the maximum brightness is up to 9200K, which is a typical cold screen. The 100 nit brightness closer to the daily use environment is used for the test. The color temperature is about 8400K, the average deltaE is 6.5, and the maximum is 14.9. For comparison, Note5 is 1.8 and iPhone 6s is 2.6 at the same brightness.
The color of this screen is very bright, the color temperature is cold, the brightness is enough, but the color accuracy is average. In addition, The screen will be red to a certain extent, and there will be a slight smear when sliding, but it does not affect the use of the screen.
System&Fingerprint
The machine is equipped with EMUI 4.1 based on Android 6.0, In addition to improving the smoothness, it is hard to detect that the system has used the Android 6.0 kernel. About 12 third-party apps are pre installed on the mobile customized version, 6 of which are mobile and can be uninstalled by themselves.

Authority management and power optimization
Although it is the main model for young users, the factory default theme needs to be improved. EMUI follows a large and comprehensive path. The system has many advanced functions that other systems do not have, but the overall planning is still lacking. For example, some functions such as bootstrap management will appear in many places. Although it is beneficial for users to find the target function, it will make the setting page longer and increase the difficulty of memory.
The overall ease of use of the system is very good, and the system has made very radical settings for the self starting and power saving management that the domestic environment attaches most importance to:
The priority of applications switched to the background will be very low. Even GPU GFLOPS, an application with high CPU usage, cannot eat all the computing performance after clicking Home to switch to the background;
By default, the system will restrict background applications 10 minutes after the screen is locked;
It comes with associated startup control that is rare in domestic customized ROMs;
Like MIUI, it will close all floating windows of third-party applications by default, requiring manual unsealing, etc
The result is users It's okay But geek users may need one or two more steps to use it. EMUI The daily functions and features will not be described in detail. Later, we will conduct separate evaluation and comparison for each domestic ROM system, and interested readers can pay attention to our future articles.
Fingerprint input and identification speed have always been the advantages of the back fingerprint identification scheme. The youth version of Huawei G9 only needs 5 times of pressing to complete fingerprint entry, and the finger can be placed on the identification module to identify and light up the screen. Identify speed and Most of the machines in the back identification scheme are close to , not prominent , but It is faster than most positive fingerprint recognition machines, including the iPhone.
In terms of functions, Huawei has added many functions to the identification module. In addition to unlocking the screen, calling out Alipay from the information screen, and application locks, it also has the function of drawing down the notice bar, sliding left and right to switch pictures, and long press to take pictures, answer the phone, and stop the alarm clock. The practicability is good.

Light scene sample
Weak light proof sheet
The youth version of Huawei G9 is equipped with a front 8 million+rear 13 million camera and an IMX214+F2.0 aperture. This is the standard CMOS of the previous generation of domestic flagship. The basic imaging strength is OK. The main problem is that the number of pixels is not high, and there is no phase focusing.
Use experience: The focusing and imaging speed of the machine is in line with the rules, the success rate of focusing is good, and the machine can basically focus in dark light. The machine can automatically judge whether the night view mode is triggered, but the HDR function still needs to be started manually. Its HDR strength is light, the processing trace is small, there is no ghost and obvious white balance change, the effect is good, and it can be normally opened for daily use.
White balance/saturation: the contrast and saturation of the machine are very high, even in weak light, there is a relatively high color saturation. The white balance tends to be blue and cold to a certain extent. Shooting colorful scenery such as flowers and green leaves will be more pleasing to the eye.
Discrimination: The sharpening trace of the finished product is very light, and the discrimination and dark noise control are the conventional performance of the 13 million pixel camera of the domestic mobile phone. Because there is no optical anti shake, the discrimination will be significantly reduced in indoor, lighting and other slightly weak scenes.
On the whole, the imaging of this camera is not different from that of the previous generation of domestic flagship, and the performance is satisfactory.
Panorama mode sample
The panoramic mode of the machine can take pictures of about 220 degrees, with a total of 64 million pixels (14208 * 4032). With light traces, the availability of the machine will be good in the daytime scene with good light. However, because there is no optical anti shake, it will be affected in the evening and in the poor indoor lighting environment.
Left: automatic mode Right: food mode (high contrast and high saturation mode)
Left: automatic mode (triggered night view mode) Right: super night view mode (long exposure of nearly 15 seconds)
There are some small functions in the machine, such as food mode, super night view and streamer shutter. The effect is OK, but except for food mode, which is convenient for girls to "test drugs before meals", the use frequency of other modes may not be too high.
performance
Huawei G9 Youth Edition (not all Netcom Edition) and Glory 5C are the only models equipped with Kirin 650 for the time being. For many users, the performance of this SoC is the biggest suspense of the machine. Kirin 650 adopts the 16nmFF+process, 4 * 2.0GHz A53+4 * 1.7GHz A53, and the GPU is T830MP2. From the parameter point of view, it is Huawei's customary "strong U and weak display" setting.
Kirin 650 is like the Helio P10 (MT6755) with a 16nm process and a small cluster of core high-frequency versions. Of course, the author also agrees with this. On mid and low-end SoCs, the improvement of CPU performance will lead to a significant improvement in fluency, while the target users themselves have few game requirements.
In order to compare the performance of Kirin 650, we found MT6755 (the test machine is OPPO R9), MT6795 (the test machine is Hongmi Note3 dual Netcom version) and Snapdragon 616 (the test machine is Hongmi 3) with the same 8-core A53 size core structure as the comparison objects.
MT6755 is the mid end SoC of MTK's traffic volume this year. It is used on OPPO R9, Meilan Note3 and other machines. The MT6755 adopts a 28nm process. Generally, four "small cores" can run 1.4-1.5GHz, while four "big cores" can only run 2-3 at 2.0GHz at the same time. Even though there are many performance constraints, these models have shown good fluency, so the author's personal expectation for the CPU performance of Kirin 650 is relatively high.
MT6795 is the last generation of high-end SoC of MediaTek. The highest dominant frequency can reach 2.2GHz, 28nm process. The Snapdragon 616 is a common choice for domestic mid end all Netcom machines. The 28nm process, 4 * 1.2GHz+4 * 1.5GHz, and the actual CPU performance should be the weakest of the four.

Flash memory read/write performance test
The actual score running result is directly related to the dominant frequency of large and small cores. The CPU ranking is 6795>Kirin 650>6755>>Snapdragon 616. In detail, Kirin 650, the most advanced in manufacturing process, not only beat the 6755 with the highest frequency of 2.0GHz, but also beat the 6795 with the higher dominant frequency in the single core test of GeekBench3.
Among them, the "small core" of Kirin 650 has a higher frequency, and all scores are better than 6755. However, in the multi-core and multithreading test, there is still a certain gap between Kirin 650 and 6795 with 8 cores and a maximum of 2.2GHz. For the GPU, Kirin 650 is also stronger than 6755 and weaker than 6795, but the gap is more even. It will have some pressure to play large games. The reading and writing performance also depends on the performance of the matched eMMC chip. The reading speed of the machine is good, but the writing speed is average.
CPU of Kirin 650 There is no core setting and frequency The regulation is very active. You can often run at the highest frequency. The secondary frequency is 1.3GHz+1.4GHz. Even when the core is idle, it can be set at 1.4GHz, which is crazy.
It is reflected that in actual use, there is little pressure on machine fluency, GPU presents a good curve, and running Taobao, Weibo and other frequently used (du) applications rarely exceed the green line. However, in third-party apps such as Weibo Taobao, in addition to loading and high-speed sliding, the CPU rarely runs at the highest frequency, which may be limited to control power consumption.
Single core copying machine, 8-core copying machine, CPU and GPU baking together
In the copying test, the single core power of the machine is about 0.8W, the 8-core full open power is 1.8W, and it will be about 2.4W when the GPU is added (The software detects the power consumption, and the value is only for reference) 。
When the CPU is copying the machine, it can always keep the maximum frequency of 8 cores fully open, and there is no sign of frequency reduction for nearly 8 minutes And the fuselage is only warm. When the GPU is baked together, the CPU will be limited to 4 * 1.8GHz+4 * 1.7GHz, but the frequency will not be reduced for a long time. There will be an obvious increase in heating. There will be a certain amount of heat accumulation above the metal frame, but it is not hot. The power consumption control of 16nm 8-core A53 is really exaggerated.
In general, the settings of Kirin 650 in the mid tier SoC are very balanced. With the advantage of low power consumption, the CPU can often run at full speed. As a result, the power consumption of Kirin 650 is much lower than that of the 6755 with similar power consumption, and much lower than that of the 6795 with stronger power consumption.
Endurance&fever
Huawei G9 Youth Edition is equipped with 3000mAh batteries. The power consumption pressure of 5.2 inch and Kirin 650 is low, and the endurance should be better. After 30 minutes of large-scale games (NBA 2K15), 30 minutes of wifi surfing, 1 hour of music playing and 30 minutes of local video playing, and 76% of the remaining power after 2.5 hours of endurance test, close to Mate8, with excellent performance.
Half an hour after the game, the highest temperature on the front of the machine appears below the earpiece, about 40 degrees; The highest temperature on the back appears on the left side of the fingerprint identification module, which is about 41 degrees. Because the back is made of plastic, the machine is only warm handed at this time. The original 5V1A adapter is used for charging, 0-90% charging takes 2 hours and 40 minutes, and the charging speed is really slow. It is recommended to equip a 5V2A charging head for daily use.
summary
The Kirin 650, which we most care about in this evaluation, is indeed more balanced than the MT6755 and Snapdragon 616 players of the same level, depending on the advantages of the process. It is a SoC that is very suitable for light users. It can use sex and control power consumption.
but The positioning of P9 Youth Edition is close to that of Samsung Galaxy A series, even higher than that of vivo, OPPO and other manufacturers. As a midrange computer, its screen and photos are the conventional level of the domestic flagship the year before last, regardless of its appearance. However, thanks to the rapid development of processor performance and domestic customized systems, its performance, power consumption and ease of use must have surpassed many old flagship computers.
Whether it is worth the price depends on how much premium Huawei can provide in addition to configuration. This may be the brand logo, appearance, or even belief. We won't comment here.
