OPPO launched R9s and R9s Plus at the end of 2016, both of which continue the design style of the R9 series, but have made some bold upgrades on the basis of the former. For example, in recent years, OPPO innovatively used 0.3-m micro slot antenna on R9s/R9s Plus, so that the antenna partition strip is no longer a roadblock affecting the beauty of the back cover. Of course, as OPPO's last work in 2016, the R9s Plus has also been upgraded in terms of hardware. This time, it uses a customized Sony IMX398 sensor, which focuses on taking photos. Let's see how this product performs.
Packaging and appearance
In terms of external packaging, R9s Plus follows OPPO's consistent packaging style, and adopts pure white packaging box+symbolic green OPPO+silver product model.
The overall packaging is quite simple and unconventional.
The real R9s Plus can be seen after the upper cover is pulled out, which is protected by frosted wrapping paper.
In terms of accessories, the quick charging head, instructions, earphones and special USB data cable are attached.
The attached charging head is a 5V 4A fast charging head dedicated to OPPO.
The overall appearance basically continues the design of the R9/R9s series. In addition to the slightly larger size, it is almost the same as the R9s. The black edge is very narrow, and the appearance is good.
There was a protective film on the surface, which felt good, and the opening was very accurate, which is also OPPO's consistent conscience.
The R9s Plus on our hand is a gold version, so the edge of its Home button is also gold.
The Color OS 3.0 operating system is installed on the site, which makes the interaction logic simple and direct, the system is clean, and there are no redundant applications.
The design of the back continues the design of the R9s. Although it is a three-stage design, the antenna partition strip has been specially treated, so the color difference is small and the integrity of the back cover is strong.
The rear camera is equipped with a 16 million pixel camera, the Sony IMX398 sensor customized by OPPO, an aperture of f/1.7, optical anti shake, and dual color flash.
The 0.3mm micro slot antenna is used as the antenna partition strip, so there are only three shallow marks across the fuselage at the antenna partition strip. The consistency of the metal back cover is much better than that of the traditional antenna partition strip.
Although the micro slot antenna is not a revolutionary design, its aesthetic quality has been improved, and users no longer have to endure the ugly white strip antenna. The metal protective ring of the camera has very small protrusions, which will not affect the flat placement of the whole machine.
The bottom partition strip also uses a micro slot antenna, which is slightly protruding to the touch, but in general, it is very harmonious and unified with the fuselage. The metal of the rear cover is sandblasted twice, which makes it soft and smooth to the touch. The micro sanding treatment is also not easy to leave fingerprints and sweat stains.
The metal integrated rear cover adopts an arc transition, and the frame is quite round. In addition to good ergonomic design, it has a good holding feeling, and almost no feeling of scratching the hand. However, the size of the body is too large. If you need to click the power/volume button when holding the single hand, you need to adjust the holding posture.
The width of the border and the width of the black edge of the screen are well controlled, so the proportion of the screen is still outstanding. Although the front face looks like a doll face, it is still outstanding.
The control of border width and screen black edge is excellent.
In terms of the frame, the design of the top of the fuselage is simple, with only a noise reducing microphone.
There are many holes at the bottom of the fuselage, including 3.5mm headphone jack, call microphone, Micro USB interface and speaker holes.
There are only volume buttons on the left side of the body.
The SIM card slot and the power button are located on the right side of the body, and the power button is located on the upper side, But the length is relatively long, and it is still relatively easy to press even if it is a single handheld grip.
The design of both the back and the frame is quite simple, without any redundancy.
Performance and system experience
OPPO is quite diligent in the system. Color OS has always been regarded as a good system manufacturer among domestic manufacturers. The system is simple and smooth, and there are no redundant junk applications.
OPPO R9s Plus came out with the Color OS 3.0 operating system, which continues OPPO's traditional UI style. It is still classic and endurable, but it is somewhat aesthetic fatigue now. Fortunately, it has a built-in theme store, and there are many free themes that users can change according to their own preferences.
The overall color matching is mainly light tone, which is relatively simple and bright, and looks very clean. Its Color OS 3.0 is customized based on Android 6.0.1, and the overall use is smooth and smooth. The speed of opening and switching applications is also commendable.
Processor performance
In terms of processor, R9s Plus uses Qualcomm Snapdragon 653 processor, which is still outstanding in terms of processor performance. Its score is even higher than that of the models with the same level of processors. Especially in terms of RAR multithreading and pi, R9s Plus is slightly ahead of other models with Snapdragon 652/653.
Graphics Processor Performance
In terms of GPU performance, the R9s Plus also showed certain advantages. In terms of the scores of the graphics performance in the postgraduate entrance examination, it has certain advantages over the models of the same level, but the advantages are not obvious.
Memory read/write score
In terms of memory read and write performance, the R9s Plus performs fairly well, basically the same level of products, and is not outstanding in random read, but it is outstanding in continuous read and write.
screen
In terms of screen, OPPO R9s Plus uses a 6-inch IPS-NEO negative LCD from JDI, with the highest brightness of 649.89 nits and contrast of 2054:1. Both brightness and contrast are excellent. In terms of color gamut, it has 132% sRGB and 89.2% Adobe RGB, which is still acceptable. The color temperature is about 7800k, which is relatively cold. In terms of color standard, the average DeltaE is 4.7, and the highest is 9.6.
photograph
In terms of cameras, OPPO R9s Plus uses a customized Sony IMX398 sensor, with 16 million effective pixels, a large aperture lens with an aperture of f/1.7, and OIS+optical anti shake, which is also a promising photographic masterpiece of OPPO in the near future. Next, we take the one plus 3T which is the same as OPPO as the reference object, and one plus 3T uses the Sony IMX298 sensor, It is also 16 million pixels+OIS optical anti shake.

The color orientation of the two is slightly different. One plus 3T will be relatively red. The R9s Plus is slightly more accurate in the color restoration of the main object, and its text edge sharpening effect is more obvious. However, its exposure is slightly insufficient. The part with a little backlight is obviously not as bright as one plus 3T, especially the leaf part at the bottom. In addition, although they are both 16 million pixels, the addition of 3T is obviously better in the details of plant branches and leaves.

In the scene of testing the analytical power, under the state of daylight recharge, the two can be said to be equal. Both details and white balance are very close. After all, the IMX398 used by R9s Plus is customized based on IMX298, and it is not surprising that they are quite similar.

In the scene testing the ultimate discrimination, the performance of the two is similar, but the sharpening effect of the R9s Plus is slightly more obvious, so in the ultra long distance scene, its small win plus 3T. However, it should be noted that the R9s Plus is still not as high as one plus three in the shadow part that cannot be exposed to the sun, which to some extent indicates that the tolerance is slightly lower than one plus three T.

In the scene of testing details, both of them are equally excellent at restoring leaf vein lines. However, in other aspects, the performance of R9s Plus is somewhat unsatisfactory, and the white balance is somewhat blue, so the restoration of red leaves and green leaves is not accurate enough, and the color should be darker. Moreover, some parts are overexposed, such as the fence at the bottom, which also lost some details. However, on the whole, for models with similar sensors and the same pixels, it is difficult to open the gap in the scene with sufficient light.

In this group of samples under non strong light, although the appearance of one plus 3T is better, it is true that the white balance and color restoration of R9s Plus are more accurate, and the color of leaves is closer to reality. There is not much difference between the two in the details of the main object, but the details of the surrounding leaves are obviously better preserved with one plus 3T. On the contrary, R9s Plus has some serious smearing marks on these parts that are closer to the solid color, and many details of the leaves have been smeared and covered.

In this scene, the appearance of one plus 3T is better, but the white balance of the R9s Plus is more accurate. Overall, the R9s Plus is more close to the true color, while the color of the sky and glass of one plus 3T is somewhat blue, which may be easier to attract users' eyes. In addition to the more accurate white balance, R9s Plus also does a better job in preserving the dark part series. R9s Plus has some reservation on the texture at the bottom of the eaves, which is basically distinguishable. One plus 3T has basically become black in this part.

In the dark light environment at night, the R9s Plus is a little defeated when it faces an increase of 3T. The brightness and details of the picture are not as good as that of an increase of 3T. In addition, there are too many noise points, which are not clean enough, and the sense of smearing is heavy. Although there are many noise points when adding 3T, the smearing is relatively uniform, and the appearance is also much better. In terms of white balance, the R9s Plus is slightly better, and it is slightly red when adding 3T.

In this set of scenes testing details, R9s Plus is still subject to smearing and noise. On the right side of the leaves, one plus 3T still retains some details, and R9s Plus has been smeared into one piece. Moreover, its HDR mode takes a long time to shoot, which also affects its focusing accuracy to a certain extent, and the film rate is average.

Finally, in the scene of testing the power of discrimination, the R9s Plus has reached the level that ordinary domestic mobile phones should have, but there is still a certain gap from one plus 3T. The longer the exposure time, the higher the picture brightness, showing more details in the performance of non main objects, but the main object has lost some details due to too long the exposure, The text at the bottom of the signboard has been completely invisible due to overexposure.
On the whole, the photo performance of the R9s Plus is commendable, and it is relatively excellent among domestic models, especially in the daytime performance, it is comparable to the nearly strongest domestic camera model plus 3T, and even better in white balance performance. However, in the performance of night scenes, it can only be called "moderate". Although it has reached the level expected by the domestic flagship, it still has a big gap with the performance of one plus 3T at night. Especially in the photography experience, its HDR mode takes a long time to shoot and needs a long time to maintain a stable grip, which is not very friendly for ordinary users.
Charging&endurance:
In terms of batteries, the R9s Plus has a 4000mAh lithium-ion battery built in, which is nearly 1000mAh higher than the R9s. The capacity is still considerable. In terms of fast charging, the VOOC flash charge, which is commonly used by OPPO, supports 5V 4A fast charging. Let's see how the device performs.
In terms of endurance, the R9s Plus equipped with a 4000mAh lithium-ion battery is still outstanding in terms of endurance. Although the battery is 120mAh smaller than the R9 Plus, there is no shrinkage in our 3-hour endurance test. It is the same as the R9 Plus, which is also 74%. It is still one of the models with outstanding endurance at present.
In terms of fast charging, the R9s Plus can achieve a charging speed of 4.5V 3.5A, and the actual charging power is about 16W. The speed is still acceptable, which is basically at the same level as the fast charging of the QC standard.
In terms of heating, after about half an hour of NBA 2K15 testing, the maximum temperature of the front side is 46.4 degrees Celsius, and the maximum temperature of the back side is 44.8 degrees Celsius. Although the heating is still acceptable, and the heating parts are concentrated in the middle and upper parts, the temperature performance is somewhat higher for a model using Snapdragon 653, Touch the upper part of the fuselage, you can still feel it is warm.
summary
As the last work of OPPO in 2016, the R9s Plus performs quite well on the whole. With a 6-inch screen, it inherits the excellent design of OPPO. Although it seems difficult to distinguish its model at first when smartphones are becoming more and more homogeneous, it is definitely an exquisite one in the Taowa face group, The super narrow border and excellent control of the screen black edge are the trumpets that make it stand out.
In addition to its exquisite appearance and consistently excellent workmanship, its endurance and photography are eye-catching selling points. R series Plus models have always had outstanding endurance performance, and R9s Plus is no exception. In terms of photography, with the customized IMX398 sensor, its photography level has been improved by leaps and bounds. Its daytime performance is not as good as that of Yijia. Although its performance at night is still not as good as that of Yijia, it has become the first array of domestic camera phones.
