OPPO has always left a deep impression on us. From star endorsement to five minutes of charging, OPPO has achieved success again and again in ways that netizens can't understand. With the rapid growth of sales, OPPO has ranked the first in China's mobile phone market shipments in 2016 (data from IDC). How did the OPPO smartphone, which has never been known for its performance, win the first place in the booming domestic market? This time we want to find the answer from OPPO R11.
Specifications
OPPO R11 uses Qualcomm Snapdragon 660 SoC, a 5.5 inch 1080P AMOLED screen, a front camera of 20 million pixels, a rear camera of 20 million pixels (IMX350 F/2.6)+16 million (IMX398 has no OIS F/1.7), a 4GB RAM+64GB ROM, a battery capacity of 3000mAh (supports VOOC flash charging), and a front fingerprint recognition using ColorOS 3.1 (Android 7.1.1).
appearance
OPPO R11 uses the usual box type outer packaging of OPPO R series. After opening the packaging, we can see several conventional sets besides the whole machine: data cable, quick charging head, clamping needle and instructions. There are three versions of OPPO R11: black, gold and rose gold Love to play computer games I got the gold version.
OPPO R11 still adopts the anodized integrated metal body. Different from the previous one, the overall thickness of OPPO R11 this time is less than 7mm. The back of the whole machine is slightly curved, which is thin and fits the palm. The overall grip is probably the best since the release of OPPO R series.
This OPPO R11 adopts the design of micro slot antenna 2.0, and the antenna is very thin and narrow.
Although the back design of the whole machine is quite different from that of OPPO R9s, if we just look at the front panel of R11, we will find that the difference between the two is very small. The location and layout of the Home key, earpiece and front camera are very similar, and the metal of the back panel is still extended to the middle frame of the handheld, CNC cutting is adopted at the junction between the metal body and the front panel of the screen.
Although the back camera of OPPO R11 is slightly convex, due to the smooth arc transition of metal around the periphery of the dual camera, the convex dual camera has no sense of conflict.
OPPO's R series each time includes two mobile phones, one large phone and one small phone. This time, it is no exception to bring us R11 and R11 Plus. According to past experience, OPPO uses different SoCs on large and small computers, and the SoC of small computers tends to be lower end, which has become a problem for many OPPO users. Small computers may have a better feel, but their performance is slightly poor. However, OPPO treated R11 and R11 Plus equally this time. The first Snapdragon 660 was used on both R11 and R11 Plus, and its performance was far better than that of the previous generation of R9s, the Snapdragon 625.
This time, R11 is still the main photographing function. Slogen changed from "clearer at this moment" to "clearer photographing" in R9s. OPPO finally used the dual camera scheme on the R series, and the rear camera is 20 million+16 million.

The overall performance of the AMOLED screen of OPPO R11 is not much different from the previous OPPO series, which is also expected.
performance
OPPO R11 is the first smartphone on the market with Snapdragon 660 and launched on the market. From the name of Snapdragon 660, it is a mid-range SoC positioned after Snapdragon 835, which corresponds to the previous generation of Snapdragon 652. OPPO R9s Plus uses a small upgraded version of Snapdragon 653, which is better than Snapdragon 652. From the comparison of running points, the GPU Adreno 512 of Snapdragon 660 is higher than Adreno 510 of Snapdragon 653, which has significant advantages in graphics performance. In terms of CPU, it can be seen that Kryo 260, a Snapdragon 660 core modified based on A73, is not much better than the A72 core of Snapdragon 653 in terms of GeekBench4 single core performance, and this gap may even be caused by the main frequency difference (the highest single core of Snapdragon 660 is 2.2GHz, and the highest single core of Snapdragon 653 is 1.95GHz).
game
At the press conference, OPPO said that it was the partner of King Glory. At present, King Glory has also opened the high frame rate mode of OPPO R11 series models. Not only that, but in the official statement of King Glory, the "multi-core multithreading technology" released by King Glory currently only supports R11 series models. In the actual game, OPPO R11 performs well, and can be stabilized at 50~60 frames in general, and group warfare can basically maintain the level of more than 50 frames.
photograph
Before starting the photo evaluation, we first entered the engineering mode to check the front camera sensor model of OPPO R11. The front camera (F/2.0) of OPPO R11 uses Samsung's s5k2t7sp. We have not found any information about this sensor on the official Samsung sensor website or Wikipedia.

Although OPPO R11 does not adopt the design of pre dual camera, it is still possible to achieve the effect similar to dual camera virtualization through the algorithm inside the system. We all know that the difference between mobile phones and cameras is that their implementation principle mainly depends on "algorithms" rather than optical devices. Therefore, the virtualization of most mobile phones has a problem of film rate, and the actual sample effect will be affected by the number of false samples, the number of false samples, the number of false samples, the number of false samples and the number of false samples.
In the actual test, OPPO R11 has a high rate of pre empting and flaking. The problem of self photographing is the edge of the hair. We can see that OPPO R11 is very natural in edge processing, especially in small images, you can hardly detect the trace of edge matting. Although it is a single camera virtualization, its effect is better than some double camera virtualization on the market, which we love to work with computers.
Post
Nihilization
In the process of use, OPPO R11's double camera post camera virtual effect is obviously better than the pre camera single camera, and the film rate is also very high. In most scenes, it will not have serious virtual failure results, and even most samples are still visible after being magnified, but you need to observe carefully to see small defects on the small picture. When looking at the issue of "mobile phone virtualization", we must understand that mobile phones are also mobile phones no matter how strong they are. It is impossible to reach the level of SLR, but the gap between the two can be narrowed. These mobile phone virtualization samples may not be worth mentioning for some more professional photographers, but for many "ordinary" It means different experience for users.
We will not compare mobile phone virtualization with SLR, which is unreasonable. But if we rank domestic mobile phones in terms of dual camera virtualization, OPPO R11 is undoubtedly the first tier.

OPPO R11's photo interface is somewhat similar to that of iPhone

OPPO R11 adopts the rear dual camera scheme, with the rear 16 million (main short focus IMX398 without OIS F/1.7)+20 million (sub long focus IMX350 F/2.6). In the actual measurement process, except for very dark weak light scenes, we can basically trigger 20 million telephoto lenses when we turn on the double lossless zoom. Due to sufficient daylight, the telephoto lens of all smart phones on the market that provide twice the lossless zoom can bring much better resolution than the main camera, while at night it is another case. Therefore, we directly selected some night view samples to see the effect of OPPO R11. It is found that even in the night scene, the telephoto lens can still provide obvious analytical advantages, and the white balance will not be much different after the lens switch. It has been proved that this is not a decorative telephoto lens, and there is still room to play even in the night.
Endurance&fast charging
In terms of endurance, it is still our 3-hour medium strength test. Both OPPO R11 and OPPO R9s use 3000mAh batteries. From the results, although the capacity is the same, the endurance performance of R11 is significantly better than that of R9s. The difference between the two is as high as 13% in the whole endurance test, and even compared with the OPPO R9s Plus with 4000mAh, the difference between the two is only 2%. It can be said that the endurance of OPPO R11 is relatively strong.
In terms of charging, OPPO still uses the VOOC flash charge of "charging for 5 minutes, talking for 2 hours". The specification of the power adapter is 5V/4A. We charge when R11 has 30% of the remaining electricity, and the measured power is 16.7W, which belongs to the normal level of VOOC flash charge.
summary
OPPO still focuses on taking photos this time. Portrait mode and 2x lossless zoom add more use scenarios for users, and solve user pain points in specific situations through functional extension of photography. Although there are many smartphones equipped with dual cameras on the market, to be honest, there are not many dual cameras that are really available and usable, and OPPO R11 is one of them. If you are a user of OPPO R9s and you are willing to pay for performance and photography, R11 is also an option; If you are an OPPO mobile phone user before R9s, you will feel an all-round experience improvement after changing to R11.
