As Windows Phone is about to enter its fourth year of release, Microsoft continues to show its control over Windows Phone hardware. This control can ensure the basic experience of Windows Phone phones in some aspects. For example, devices such as Lumia 520, which cost less than 800 yuan, can run smoothly, However, Microsoft's own pace cannot keep pace with the rapid changes in the mobile phone market after all, which leads to the impression that Windows Phone hardware is often behind the times.
This article is from: PChome Yang Jiajun
This impression disappeared with the release of Nokia Lumia 1520. The launch of the Snapdragon 800 marks that the Windows Phone platform has officially entered the four core era. More importantly, in terms of hardware, the Windows Phone platform is no longer backward and has begun to keep consistent with other platform devices.
Advance summary and overview
Of course, this article only evaluates the Lumia 1520 hardware, so the content about the Windows Phone platform is not the main discussion center, but will be used as some examples and circumstantial evidence.
First of all, as a flagship smartphone, the Lumia 1520 is equipped with all the "strongest" hardware you can imagine. Of course, everyone has different understanding and definition of the word "strongest". Before starting the details, you can understand my summary of the hardware of the Lumia 1520, as follows:
1. Lumia 1520 is currently the strongest mobile phone on the Windows Phone platform. With the help of Qualcomm Snapdragon 800, its performance and indicators are far superior to those of previous models, and its running speed is impeccable. Any third-party application can be loaded and restored in an instant.
2. Lumia 1520 has a 3400mAh battery. Although the 6-inch screen is a major power consumer, it is generally a smart phone with good standby. Under the continuous operation of WeChat, QQ, Weibo, photo sharing and other operations in 3.5G network, 26% of the power can be left after 7 hours of use, and only 12% of the power can be consumed for playing local videos for 1 hour.
3. The 20 megapixel PureView camera has not destroyed Nokia's gold lettered brand, and it can meet the initial expectations for the camera's imaging effect in all aspects. With the help of the new algorithm, the white balance performance of the Lumia 1520 is the best in the current Nokia Heavyweight Lumia models.
4. The 6-inch full HD screen has excellent display effect. This screen has nothing to be choosy about in terms of brightness, saturation and visual angle. The performance of the color gamut is particularly excellent. Without starting to adjust, the color is relatively cold and comfortable to watch.
5. The size of Lumia 1520 will exceed the bearing range of many people. The 162X85X8.7mm three circumference performance is difficult to operate with one hand, but it seems that there is no pressure when it is stuffed into the pants. The 206g fuselage is not light according to the parameters, but it may be because the fuselage is relatively large, so there is no great pressure when you use it.
The above summary summarizes the Lumia 1520 from the aspects of operation, use time, photo performance, display effect and phone size. If you see this, you are interested in this phone. Next, we will start from every detail to study the hardware of Lumia 1520.

Traditional design is beautiful
The Lumia 1520 is a good continuation of the design elements of the Lumia series. The bold use of color and the curved water drop screen are reflected in the Lumia 1520. However, it has many differences from the previous generation of Lumia 1020 and Lumia 920. The subtle adjustment of this change also makes the Lumia series full of freshness after two and a half years of change.
Since N9, the use of polycarbonate materials has laid the foundation for Nokia's design, which is contrary to the coldness of most smart phones' pursuit of science and technology. Nokia's design pursues a soft and warm touch. This makes the entire Lumia series of mobile phones have a high recognition among many smart phones, and a large part of this recognition is also due to the fact that Lumia series usually uses eye-catching candy colors, such as lemon yellow, lake blue or grass green.
Lumia 1520 and Lumia 1020
The Lumia 1520 has four color schemes: yellow, red, white and black. Although the popular lake blue has not appeared, it is believed that once the sales of Lumia 1520 reach the expectation, Nokia will consider launching lake blue as the original Lumia 920 did. Unlike Lumia 920 and 1020, most of the colors of Lumia 1520 are made of polycarbonate with frosted surface, and only red is made of baking paint, which also makes the red Lumia 1520 look more enchanting.

New feeling of slim large screen
There is no doubt that the design of Lumia 1520 and Lumia 925 are inextricably linked. Of course, this connection may not be obvious on the 1520. Due to size considerations, Lumia 1520 has removed the proud anodized aluminum frame of Lumia 925 and adopted polycarbonate shell for integrity, which may be more similar to the mid end Lumia 720 at a glance. However, the slightly raised camera behind the Lumia 1520 completely sold it. Undoubtedly, it has the same design as the Lumia 925.

Of course, this design makes the fuselage look very thin. The 8.7mm thickness is not very outstanding in data, but the fuselage design will make users think that the Lumia 1520 should be a little thinner than the value. Due to the micro arc treatment of the back, the Lumia 1520 has a sense of narrowing from the side.

All the physical keys of the mobile phone are placed on the left, which may also be due to the size of the mobile phone. The volume key and power key of the mobile phone move a lot to the bottom of the mobile phone. This benefit is self-evident. Both the left hand and the right hand can easily and quickly locate these keys. Even in the dark, they can still be quickly found.

The material of the buttons is worth mentioning. Although Nokia has no official confirmation, these buttons should also use the ceramic material that is widely praised on the Lumia 920. This material, called zirconium diboride ceramics, has the characteristics of high temperature resistance and stable performance. Unlike the early gloss of baking paint or electroplating process, zirconium diboride ceramics are inherently metallic and will not fade with use. In general, it is an extremely durable material.

The eye-catching water drop screen
As a super large screen smart phone, the Lumia 1520 is basically insulated from single hand operation in terms of size, which can be seen from the three dimensions of 162X85X8.7mm. The weight of 206g is a real big man in the era of pursuing lightness, but it is not difficult to find that the Lumia 1520 is not as "heavy" as expected when you really get started. It may be that the large size of the body makes your hands less sensitive to weight. In short, when you hold the Lumia 1520, you may even have the illusion that it is lighter than the Lumia 1020, Lumia 1020 is only 158 grams.
Lumia 1520 is much bigger
The front of the Lumia 1520 is almost occupied by a whole black panel, which is no different from other Lumia devices. Of course, the Lumia 1520 has finally got rid of the disadvantage of low screen proportion of Lumia devices in the past, and has really achieved a narrow border. Although it does not reach the amazing narrowness of LG G2, it is very good visually.
Lumia 1520 has a narrow border
Since Nokia N9, Nokia has used curved glass as the outer screen. This kind of visual screen is called a "water drop" screen. In addition to making the display content of the mobile phone screen appear below the finger, when the mobile phone screen goes out, the display part will be truly "integrated" with the black panel. Lumia 1520 also uses such a screen. When the mobile phone screen goes out, the black panel and the screen area blend together to have a very beautiful screen out effect.
Humanistic design of induction keys
The Lumia 1520 still uses a slender mesh earpiece design. On the left side of the earpiece are the distance sensor and light sensor of the phone. The role of the light sensor of the Lumia 1520 is different from that of other phones, which will be explained in detail in the following screen. On the left side of the earpiece is a 1.2 megapixel front camera, which can be used for self taking or video calling.
The key of Lumia 1520 is left blank
As mentioned earlier, the Lumia 1520 adopts a micro arc treatment at the back, so the side is more rounded, which makes the phone feel more comfortable. In order to avoid misoperation when holding the phone, Lumia 1520 has made a special design for the three touch keys. It does not divide the lower key area into three equal parts, and moves the three keys closer to the middle, thus narrowing the key area. The areas that may be touched by mistake when operating the screen are left blank, which can reduce the possibility of misoperation.

Extended storage without pressure
Lumia 1520 adopts 32GB ROM, and its storage space can also be expanded by using Micro SD card, which can support up to 64GB MicroSD card. On the top left of the phone are the SD card slot and the SIM card slot. It is worth mentioning that the Lumia 1520 uses the Nano SIM card instead of the Micro SIM card. Unfortunately, Nokia still doesn't seem to support hot swapping SIM cards. Every time you unplug the SIM card, you need to restart your phone to recognize the signal.

The MicroUSB port is placed at the bottom of the phone, and there is a 3.5mm standard audio interface in the middle of the top. Top detail of Lumia 1520
There are many elements on the back of the phone. First of all, the Lumia 1520 uses the same protruding camera design as the Lumia 925, which leads to the fact that the Lumia 1520 cannot be completely flat on the table. Of course, this kind of design is very attractive. I think it is very good. There are two LED fill lights on the right side of the camera, and the PureView ZEISS logo on the left shows Nokia's confidence in the imaging of this mobile phone.

Lumia 1520 places the speaker mouth at the junction of the mobile phone's arc border. The advantage of this is that no matter what the mobile phone is placed in, the speaker cannot be really covered, so that the user will not miss any call.

The strongest IPS screen in the world
Lumia 1520 uses a 6.0 inch full HD display screen, which has reached the highest level in the industry from any angle. The 367PPI does not exceed the current small screen full HD display, but it still has a very high degree of delicacy. If it is not for a microscope or nitpicking, it is difficult to find the pixel lattice of a mobile phone.

The use of IPS materials enables Lumia 1520 to have a good white display capability. Through the adjustment of Nokia display screen settings, users can set the color temperature and color saturation of the screen to adjust the screen to their favorite state. With 178 degrees of ultra wide viewing angle, Lumia 1520 can provide the best level in the industry at present in terms of brightness, contrast, or color saturation. Nokia even ensures that the refresh rate of the screen can be kept at 60mHz. No matter what operation or animation, the mobile phone screen will not become an obstacle, ensuring the absolute smoothness of vision.
Assertive Display technology is more amazing
Of course, the Lumia 1520 screen still has two outstanding breakthroughs in technology. First, Lumia 1520 is the first mobile phone to adopt Assertive Display technology. This technology starts with both software and hardware to maximize the visibility of mobile phones in the sun.
Assertive Display
This technology, developed by Apical, exceeds all current display management functions and is contrary to the existing screen brightness management mechanism. Although it still uses light sensors to capture signals to change screen brightness, it is qualitatively different. The main difference is that in the past, by detecting the surrounding light environment, the screen brightness of the mobile phone light sensor can only carry out the overall brightness, but the Assertive Display can adjust each pixel separately to change the color of the individual pixel and improve the contrast of the screen in the sun. The effect is self-evident.
Of course, Assertive Display will have a separate chip to complete the calculation. It can be completely independent, not affected by the CPU or other SOC, and can be used independently with the light sensor without taking up the resources of the phone.
CBD is traditional
Similarly, Lumia 1520 also has its own Clear Black Display. This technology that makes black darker is regarded as a classic by many Laonuo fans. In addition to further improving the readability of the phone in the sun, it can also improve the display ability of the phone screen to black, killing two birds with one stone.
CBD technology can increase visibility in the sun
Clear Black Display is also a hardware technology. It prevents sunlight from reflecting into the human eye through the polarization effect inside the screen, so as to achieve a better display effect in the sun.
The working principle of CBD screen can be divided into the following steps:
1. The light shines on the polarizer, which vertically polarizes the light. In short, it deflects the light wave vibration in a specific direction.
2. The light shines on the cyclic polarization delay layer. The delay layer changes the vibration direction of the light again to achieve light polarization.
3. Then the light shines on the screen layer and rebounds.
4. The light enters the delay layer, and after penetrating the delay layer, the light is horizontal and direct;
5. Finally, the light shines on the linear polarizer. Since the light is already horizontal and direct at this time, it is completely blocked by the linear polarizer;
Snapdragon 800 Breaks the Limit
The most breakthrough point of Lumia 1520 is that it is the first time to use a quad core processor in the Windows Phone platform. It is also mentioned in the preface that the hardware of the Windows Phone platform has always been backward due to Microsoft's own control of the hardware, but this has been completely solved on Lumia 1520, With the use of Snapdragon 800, the hardware of the Windows Phone platform devices has kept pace with the Android platform for the first time.
Snapdragon 800 processor
In addition, the Lumia 1520 is also equipped with 2GB of running memory, which further ensures smooth operation. The running speed and efficiency of the Lumia 1520 is the most outstanding among the current Windows Phone phones. The third-party applications that used to get stuck in the past, and the games that got stuck without optimization, can run smoothly on the Lumia 1520 without any problems.
High performance hardware makes people have questions about the heating of Lumia 1520. In actual use, The Lumia 1520 is very cold most of the time. Only under the high-intensity network application and games can there be a slight heat. The hot spot is located at the top right of the mobile phone camera, which avoids the part that may be held by the hand very well. Even if it is hot, it is difficult for users to really detect.
The 3400mAh battery also guarantees the phone's life. As summarized in the preface, the life of the Lumia 1520 can support more than 7 hours of 3G network use, or up to 8 hours of video playback. It is possible to use it for a day normally.
20 megapixel PureView camera and outdoor samples
Lumia 1520 is equipped with a 20 million pixel PureView camera, which also uses OIS optical anti shake. If you really want to position Lumia 1520's photographic ability, you can only use samples to speak. I divided it into outdoor, macro, indoor and night scenes to judge.
Lumia 1520 still adopts PureView technology
The first is the outdoor sample. Lumia 1520 uses high pixels and can save the next 5 million and 20 million pixel photos at the same time. Users can use small photos for network sharing, and large capacity photos for post-processing and other operations. The photography color of Lumia 1520 changes from the saturated and rich style of Lumia 1020 in the past, and pursues realistic restoration. High pixels can retain good details.
Backlight performance is the same as eye-catching
Backlight is a scene we often encounter in taking photos. Lumia 1520 also performs very well in the backlight state. Let's take a look at its sample in the backlight state.
Good imaging day and night
Next, let's take a look at the performance of Lumia 1520 in night imaging. It can be said that night imaging is a very important link. Since Lumia 920, Nokia has had a very outstanding performance in night imaging. Lumia 1520 also continues this advantage. Nokia camera itself provides an automatic mode for night shooting.
Excellent macro image quality
Macro proof is also a very important part of life. Next, let's take a look at the performance of Lumia 1520 in macro imaging. From the proof, we can see that Lumia 1520 has a very good focusing ability in macro, and also has excellent control over the details and sharpness of the film.
Indoor imaging is well restored
Lumia 1520 also has a good effect in indoor imaging. Unlike outdoor, weak light and other phenomena often occur indoors. Lumia 1520, which has OIS optical anti shake, continues the traditional advantages of Lumia series and has a good performance.
Excellent PureView, easy to take photos
In general, Lumia 1520 maintains PureView's consistently high level of imaging capability. Due to the use of 1/2.5 CMOS, it has a good advantage in detail expression, and Nokia has strengthened new algorithms, so it has made great progress in white balance compared with the past.
Secondly, although the expressiveness of Lumia 1520 is very eye-catching, there is still a clear gap between Lumia 1520 and its own Lumia 1020. Especially in the detail reduction part, it is almost high and low. This does not mean that there is a problem with the Lumia 1520. On the contrary, in many scenarios, the imaging of the Lumia 1520 is almost better than that of all smartphones except the 808 and 1020. It can only be said that Nokia has no intention of developing the Lumia 1520 to the extreme imaging. In exchange for a thinner lens module, it can further reduce the thickness of the body.
The most powerful one deserves it
Lumia 1520 is the best cross-border product that Nokia can offer in all aspects. As I summarized earlier, it almost includes the most top hardware in the industry: the best screen, the 20 million pixel camera supported by PureView technology and the Qualcomm Snapdragon 800 processor. As the Lumia 920 released last year, Nokia has completed a coordination and optimization on the hardware, eliminating the false and retaining the true, and made a truly excellent and durable smart phone. Different from the weakness of Lumia 920 in core CPU last year, this time Lumia 1520 has achieved the highest level of smart phone hardware in all aspects.
Lumia 1520 is much thinner than Lumia 1020 in thickness
For the Windows Phone platform, Lumia 1520 has also solved the problem of poor hardware that has plagued Windows Phone. If this is no longer an obstacle to the Windows Phone platform, does it mean that Lumia 1520 will become a milestone of Windows Phone? You should know that among the large screen cross-border mobile phones currently using Snapdragon 800, Lumia 1520 is the lowest price. Whether it is Sony's XL39h or Samsung Galaxy Note3, its listing price is more than 5000. Low price and excellent quality will become the prerequisite for hot sales. Of course, this is just an idea. The market will still give us the most true answer whether it will really become like this.
