Over the past few years, the great success of Samsung's Note series needs no more words. The Galaxy Note series has created a new product category, and Samsung is not only satisfied with making the screen bigger, but also the fact that the Note series is crammed with super powerful hardware configuration and exclusive functions is also the reason why consumers are eager for it. Compared with the S series, it is obvious that Note is the real flagship.
Specification and appearance:
Note 4 evaluated in the original text is Qualcomm Snapdragon 805 processor version, and Exynos version may be slightly different.
In addition to the improved hardware configuration in all aspects, the most eye-catching feature of Note 4 this time is the newly added metal frame and curved glass screen. The two are well combined by Samsung, and the overall visual effect is excellent.
The front is still the classic Samsung style. The large screen plus the physical HOME button at the bottom, the 3.7 megapixel front camera is placed on the upper right side of the fuselage, and the silver earpiece and the Samsung logo are still in the middle of the forehead. To our satisfaction, the HOME button with fingerprint scanning is much better than the one on Note 3.
Note 4 on the side of the fuselage adopts a design similar to Galaxy Alpha. The power button is placed on the right side of the Samsung mobile phone for easy operation, and it feels great when pressed. It is more comfortable than many competitors. The exquisite aluminum alloy frame has a circle of polished chamfers to ensure the grip of the mobile phone, The metal frame also makes Note 4 more advanced than Note 3 and S5.
The back of Note 4 is still plastic in imitation of leather, but the false seam pattern on Note 3 is abandoned. The speaker is also moved from the bottom to the back. The feel of the plastic back cover is closer to real leather. The combination of the plastic back cover and the metal frame is also very clean.
In general, the appearance of Note 4 is a big evolution compared with that of Note 3. For a mobile phone that can remove the back cover, this design is already very excellent. However, the author personally hopes that Samsung can use a pure black panel on the front to highlight the high contrast of the AMOLED screen.
Endurance and charging:
In the endurance test, we set the screen brightness to 200nit. Compared with Note 3, the battery of Note 4 is only 3% larger, so we think that the endurance improvement of Note 4 should be due to more efficient hardware, rather than simple battery capacity.
Note 4 performed well in our web browsing test. The continuous web browsing time reached 11.97 hours in the WI-FI state and 11.11 hours in the LTE state. The endurance score easily killed Note 3. Although it is not as good as the iPhone 6 Plus, Note 4 still has no problem in using it for one day.
In terms of charging time, Note 4 achieved 1.76 hours of charging time from 0% to 100%, which is very excellent. Note 4 will automatically switch between 9V/1.64A and 5V/2A when charging. Note 4's excellent charging speed is also mainly due to the built-in fast charging technology, and the charging speed will slow down after the battery reaches 50%.
Screen:
The screen of Note 4 is a 5.7 inch AMOLED screen with a resolution of 2K. Such a high PPI makes the display effect very delicate.
The maximum brightness of the Note 4 screen in the automatic mode can reach more than 450 nit, enough brightness to ensure excellent outdoor visibility, and the maximum brightness of the manual mode is only about 330 nit. However, the Note 4 screen still does not solve the problem that AMOLED has shadowing in low brightness, but this problem does not exist in high brightness.
The grayscale performance of Note 4 is quite good, but there is still a visible greenish phenomenon. Although the greenish phenomenon is not common, it is only visible on some grayscales, but it is still an aspect that needs to be improved.
In terms of color saturation accuracy, Note 4 performs well. The value of 2.24 in the standard mode of the dE2000 has ensured that users will not be aware of obvious color deviation.
In the GMB accuracy test, Note 4 performed well, making great progress compared with Note 3. There are many display modes in the screen settings of Note 4, People who like bright and vivid colors with high saturation and pursue accurate colors can be satisfied. However, the screen of Note 4 will have a certain color deviation when changing the viewing angle, but in general, The AMOLED in Note 4 has reached the highest level of AMOLED at present, even surpassing the LCD screen in some aspects. We also hope to see the day when AMOLED's performance in all aspects will surpass that of LCD.
Photographing and imaging:
The Snapdragon 805 version of Note 4 uses Sony's IMX240 sensor, which can take up to 16 million pixel 16:9 photos with optical anti shake and F/2.2 aperture. The front camera is Samsung's own sensor with the model of S5K6D1YX. There is no more information about this sensor at present.
In addition to the image quality, we are also very concerned about the use experience of taking photos, because no matter how good the image quality is, it is useless to shoot what we want. Unfortunately, Note 4 does not use continuous focusing technology, and the average focusing time of Note 4 is 800 milliseconds without touch focusing, When the user manually selects the focus using touch focusing, the focusing speed can be less than 300 milliseconds.
We use the ISO table to test the maximum resolution of photography. In this test, the output image quality of Note 4 is similar to that of S5, the image resolution is high enough, and the detail restoration of the table is also in place.
Daytime sample (compare with S5):
S5：
Note 4：
In the daytime landscape sample, Note 4 gave a satisfactory answer with excellent detail performance and dynamic range, but there was some detail loss on the grass, and there was also some color overcorrection on the bleachers at the far end of the picture.
Night view sample (compare with S5):
S5：
Note 4：
In the night photos of the same location, the picture quality of Note 4 is significantly improved compared with S5, but Note 4 has obvious smearing on the buildings on the right side of the screen, resulting in some loss of detail.
HDR sample (compare with S5):
S5：
Note 4：
In the HDR photos, Samsung's performance is as good as ever. Most of the details of the picture are well preserved, and there is no halo around all the scenes, even there is no ghosting on the walking pedestrians. Therefore, we speculate that the HDR of Note 4 is based on the HDR of the hardware level, rather than the result of taking multiple photos for later in machine synthesis.
Processor and flash memory performance:
The Snapdragon 805 built in Note 4 is the last generation of Qualcomm processor using Krait architecture (the next generation Snapdragon 810 will use ARM's 64 bit architecture). Snapdragon 805 is one of the strongest mobile processors on the market today, and it uses TSMC's 28 nanometer high-performance mobile process to improve performance while reducing power consumption.
From the test results, the CPU performance of the Snapdragon 805 is as excellent as we expected. In fact, the performance advantage of the 805 has little to do with the super high frequency, but more to do with the architecture.
The GPU for Snapdragon 805 is Adreno 420, with a maximum frequency of 600MHz. Samsung has launched two mobile phones with Snapdragon 805 processors, S5 LTE-A and Note 4. The performance of these two phones in this link should be similar.
Again, the performance of Note 4 meets our expectations for Adreno 420, but the 1440p high-resolution screen makes the On screen performance of Note 4 no different from that of many Snapdragon 801 devices.
In terms of storage performance, Samsung is still in the forefront, and the test results also show that the storage performance of Note 4 will not become the bottleneck of the overall performance.
Summary:
During the period when I used Note 4, I felt that what really stood out in Note 4 was not the hardware specifications, but the excellent software experience based on the hardware. A little difference in hardware and the development of functions in software made Note 4 not only a large screen phone, but also an excellent software experience based on the previous generation of works, Note 4 adds more functions of S-Pen, which is really useful in daily use, but there are still some small flaws in the experience. Compared with the iPhone, which has just set foot in the big screen mobile phone, Samsung has more and more powerful functions and better experience.
Another satisfying aspect of Note 4 is the screen. The huge screen and high contrast make multimedia entertainment on this screen a pleasure. With the release of each generation of products, Samsung is also constantly improving the performance of the AMOLED screen. At least, this screen on Note 4 is no inferior to the screen on iPhone 6 Plus.
In 2014, Samsung finally got rid of the name of "ten thousand years old plastic". The metal frame of Note 4 makes the whole machine feel very high-end. Yes, Note 4 is certainly not the most beautiful phone with the best texture and appearance, but it is also worth affirming that it can make the appearance like this while maintaining the replaceable battery and expanding the memory.
The endurance of Note 4 is better than that of S5. However, due to the high resolution screen in the test, the performance of Note 4 is still lower than that of iPhone 6 Plus. However, it is very easy for Note 4 to maintain normal use all day long. The addition of fast charging technology makes Note 4 perform better in this respect.
The addition of optical anti shake in Note 4 has greatly improved Samsung's poor imaging at night in the past. In the case of sufficient light, the imaging of Note 4 has maintained its consistently excellent level, and the natural advantage of 16 million pixels also makes Note 4 more confident when challenging the iPhone 6 Plus.
After further upgrading the function, Note 4 is undoubtedly one of the best cross-border tablet phone products on the market. For every buyer, whether Note 4 is the best or not depends on everyone's actual needs and preferences, just like the famous saying; There are a thousand Hamlets in the eyes of a thousand people.
