Asustek Zenfone Zoom series is called "Eagle Eye" in mainland China. Last year's Zenfone MAX used the name of "Dianshen 5000". On July 17, Asustek released a new generation product of the same series, Dianshen 4, in the mainland market. In addition to the traditional endurance, the main products are seamless all metal body, 120 degree wide-angle dual camera, and easy 4.0 UI.

Appearance and design
Pure black drawer packaging, with very detailed product description on the back
The maximum output of the charging head is 5V/2A, which is slightly larger than that of domestic machines
Asus Dianshen 4 is equipped with a 5.5 inch IPS screen. The original logo of the brand has been canceled, which shows that the earpiece and front camera are in a high position
Dual camera has large volume and dual color temperature flash lamp
The top and bottom of the fuselage are independent plastic plates, which also serve as antenna overflow outlets
The frosted metal back cover is not treated with anti oil paint. It's hard to take care of
The front of ASUS Deuteronomy 4 is close to that of Pegasus 3s. It is also 2.5D glass and front fingerprint identification. It has a status indicator, but the logo is canceled. The most obvious change on the back is the introduction of dual cameras and the all metal material of the whole back. The scheme used by ASUS is very special. It directly changes the top cover and bottom of the fuselage into plastic materials, thus avoiding the design problem of antenna slot.
The left sim card slot, the right power and volume buttons, the top headphone connector, the bottom speaker, the microphone, and the mirco USB connector are all very classic layouts. On the other hand, the keys have concentric circles, and the card slots and keys are tight. It supports dual nano SIM cards or single SIM card+TF card. The injection molding process is not used at the top and bottom, and there is a slight gap, but the overall workmanship basically meets the expectations of this price level, which is a simple leather type.
In terms of grip, the rear waist line of ASUS Dianshen 4 rear cover is slightly behind, and the weight brought by 5000mAh large battery makes it feel heavy.
Fingerprint input requires about 10 presses, and the recognition speed is far faster than expected, and may even exceed the iPhone and other flagship brands with low fingerprint speed. The response of ASUS Deuteronomy 4 to light up the screen is slow. Basically, press the home button. When the screen lights up for a few seconds, the unlocking is completed. There is no animation in the middle of the process, which gives a feeling of quick unlocking. In addition, ASUS Dianshen 4 supports both WeChat and Alipay fingerprint payment, which is a feature that many mainland manufacturers do not necessarily support.
Screen: The ASUS Dianshen 4 is equipped with a 720P 5.5 inch screen. This configuration is relatively retro, and the visual perception of color is not a big problem. It is not less than the A screen with the same resolution. The screen graininess is not as serious as expected, and it is acceptable. However, the fitting glass is too thick, and the screen uniformity and viewing angle are average. The touch screen sensitivity of the machine is average, of course, this may also be related to the performance.

We use the Snapdragon 435 (8* [email protected] ）Red rice 4X and MT6753 (Meizu changed to 8* [email protected] ）5 s as the contrast. ASUS Electric God 4 It is equipped with the MT6750 of MediaTek. The CPU is an 8-core A53 architecture of 4 * 1.5GHz+4 * 1.0GHz. It is positioned as a gateway. The absolute performance of the CPU is above the Red Rice 4X and Magic Blue 5s. The performance of the 4.0 UI is fairly smooth, which is a little smoother than expected.
GPU is Mali-T860 MP2@520MHz , the performance is not strong. The GPU performance is slightly weaker than that of the Red Rice 4X, and much stronger than that of the Meilan 5s (the MT6753 is really too weak). But after all, it is only 720P resolution, so the pressure on GPU will be much less. It is still possible to run small and medium-sized games. Even NBA2K15 can run at 10-20 frames. In terms of read-write performance, ASUS Deuteronomy 4 and Red Rice 4X also have a win or lose, which is above the Magic Blue 5s.
system
European, American, Japanese and Taiwanese manufacturers generally pursue a system experience close to the original, but ASUS's thinking is more similar to that of mainland manufacturers, and the system has been highly customized. This system, called "Save the trouble 4.0", has been polished for a long time“ Desktop negative screen information flow The familiar functions such as auto start control, double click wake-up/screen out, screen out gesture, somatosensory operation, application double opening, multi task button customization, lock screen pictorial, simple mode, long screen capture are all available.
The system also has some details, such as "long press the fingerprint button to answer the call directly, the outdoor mode switch integrated with the volume bar, and the suggested value display of the automatic brightness will also be displayed under the manual brightness", which are not available in mainland domestic ROMs. Although different people have different opinions on the design of icons and UI, they must be more diligent and easy to use than HTC, Sony and other manufacturers who exchange native systems for UI. The system comes with many third-party applications. Fortunately, they can be uninstalled by themselves. The ASUS Deuteronomy 4 system, like the moto phone by default, also has a virtual key bar, which is quite puzzling, but It can be changed to the common operation mode of "tap to return, press to return to the home page, double click multi task management" of domestic ROMs.
In addition to some system and UI logic that are different from everyone's habits, some details are not perfect, and the camera app has a little bug, the completion of this system is already high.

ASUS Deuteronomy 4 is equipped with a front mounted 5 million pixels, rear mounted 13 million+8 million pixels 120 degree wide-angle camera, and a wide-angle lens on the secondary camera. The most famous example before is LG's G/V flagship series. The lens of ASUS Dianshen 4 does not have an anti oil coating, which will cause serious glare when you touch the lens by mistake. In daily use, you have to develop the habit of wiping the lens before taking photos. In addition, the camera UI also has small problems such as "repeated items, occasional imaging and metering jams" in the resolution adjustment of wide-angle cameras. I hope that the system update can solve these problems in a timely manner in the future.
The ASUS Dianshen 4 camera app interface lists many function keys directly. The advantage is that the operation efficiency is higher than that of the iPhone like camera UI. The disadvantage is that it looks more complex and has a higher chance of accidental touch. The left and right sliding are function mode and filter respectively. The camera has its own functions such as ultra clear mode, time delay and GIF. It does not support automatic HDR. Dual photography cannot use zoom switching, but the night scene can automatically trigger multiple composite images. The composite speed is about 1 second, and the speed is average.
Left automatic mode, right HDR mode
The HDR synthesis of ASUS Dianshen 4 also takes about 1 second. The HDR processing is light, which will greatly increase the exposure value. In addition to improving the dark details, it has little influence on white balance, discrimination and saturation, and the effect is OK. In addition to the slightly faster processing speed of the secondary camera, the effect and style of the HDR algorithm are similar to those of the main camera.

The 52 million high-definition mode of the fuselage is not very demanding in the daytime, and requires about 3 or 4 seconds of synthesis time. The effect can significantly reduce noise and has a sharpening effect, and the detail expression has been significantly improved.
Light proof sheet

The default tolerance of ASUS Dianshen 4 proofs is general, the metering is slightly darker than the naked eye, and the insufficient exposure of weak light scenes will be more obvious. The white balance is relatively accurate, without too much deviation, and the saturation contrast is not high, which belongs to the realistic restoration style. The ultimate discrimination force is in line with the standard, and the noise is smeared vigorously. It is difficult to see large noise spots under extremely weak light, but the discrimination force has also suffered a corresponding loss.

The 120 degree wide-angle sub camera has 8 million pixels. Like all wide-angle lenses, the number of pixels that can be allocated to a unit scene is much less, which is the exchange between vision and discrimination. Wide angle lenses are mainly used to shoot indoor and large scene landscapes. Because the discrimination is not enough, they are not suitable for taking full body photos of many people. Surprisingly, the imaging style of the main and auxiliary cameras is very close, the ultimate discrimination in the center is OK, and there is a certain degree of availability.
Endurance, charging and heating
MT6750+720P screen+5000mAh battery, providing 5-gear power saving mode. The official nominal call time is 61.4 hours, the video time is 21.6 hours, the game time is 13.3 hours, and the music time is 126 hours. In the actual test, ASUS Dianshen 4 experienced 30 minutes of large-scale games (NBA 2K15), 30 minutes of wifi and 4G Internet access, and 30 minutes of local video playback. After a total of 2.5 hours of endurance test, the remaining power was 84%, and the performance was as strong as expected. If the test time continues to extend, the gap between mobile phones will be doubled.
In addition, ASUS Dianshen 4 supports 5V/1A reverse charging and can charge iPhone or other mobile phones in case of emergency. However, considering the charging conversion rate and loss, as well as the need for an OTG adapter to use, the practicability of this function is not high.
ASUS Dianshen 4 does not support fast charging. It is equipped with 5V2A charger as standard. The charging power on the bright screen is about 2.4W and the charging power off the screen is 10W at 10% charge. The measured ASUS Deuteronomy 4 does not support MediaTek's PEP charging head and Qualcomm's QC2.0/3.0 charging head, and the charging power of both charging heads is only about 5W.
5V/2A charging is not good news for 5000mAh cell phones: 0-60% charging is slightly faster, and takes 1 hour and 30 minutes; In the middle section, 60% - 90% of the battery takes about 1.5 hours. It takes 2 hours and 50 minutes to charge 90% of the battery, and then it enters the trickle charge of 1 hour and 20 minutes. Daily use is basically charging when sleeping. In the charging curve, there will be unstable power jump when the power is low, which may be caused by inaccurate statistics of the electricity meter.
In terms of heating, after 20 minutes of NBA 2K15, the highest temperature on the front of the machine appears below the earpiece, about 50.3 degrees; The highest temperature on the back appears below the camera, which is about 44.1 degrees. The temperature is too high, and the MTK processor of the old process is also very hot.
summary
The price of ASUS Dianshen 4 is 1399 yuan, which is basically in line with expectations. The most outstanding endurance is still quite ferocious. The performance is average, and the functions such as dual camera are slightly improved. In terms of cost performance, it can't be compared with the classic 1000 yuan machines like Hongmi and Meilan. Its selling points are its different appearance design, dual camera and 5000mAh battery. It's always good to make more choices in the market. It's a question of whether it's worth buying or not. I hope everyone can have their own judgment after watching the evaluation.
