As the main model of OPPO in the consumer market in 2018, R15 launched a dual processor version for the first time. In addition to the Snapdragon 660 version, which uses a more conventional processor, it also launched a standard version of MediaTek P60 processor at the same time. This processor can be said to be quite controversial. MediaTek processors have been performing poorly in the past two or three years, especially in the high-end. It is difficult to compete with Qualcomm. Therefore, the use of P60 processor in OPPO this time is still somewhat worrying, but seeing is better than hearing. Let's take a look at the performance of R15 with MediaTek processor.

Appearance and details

In terms of appearance, R15 is not surprised to use the currently popular profiled full screen. Although the author is not impressed with Liu Haiping, it has become a standard configuration in 2018. Although it is not beautiful, it is obvious to all that the proportion of screens has increased.

Moreover, because Android models do not have Apple's complex 3D facial recognition system, the number of front sensors is small, and the width of the bangs is relatively small, so the impact of bangs on the overall experience is not as big as that of iPhone X. Originally, this location was also a location to display notifications, time, and power, which is acceptable after getting used to, The sense of disobedience is not as strong as when I first contacted Liu Haiping.

R15 dream purple back adopts progressive color design, purple becomes lighter from top to bottom, purple at the top is close to black, and the bottom is close to blue.

The blue purple on the bottom can be said to be very eye-catching. If you have to find a word to describe the back design of R15, it is "Sao".

The design and material of the back have caught up with the "trend" of 2018. Double sided glass+double camera+rear fingerprint identification are standard configurations. Since 2018, the models with metal back covers for high-end models are rare, and OPPO will certainly not miss this trend.

Under different angles and different lights, the back of R15 presents different colors. Some angles are more blue, while some angles are more purple. It's really not critical for the appearance party.

However, OPPO is obviously not prepared to stop at the gradual change of color. Recently, OPPO launched a special edition of nebula, which makes the color more dazzling. However, in terms of mystery, Dream Purple is better.

In terms of rear camera, R15 standard version is a combination of 16 million main cameras+5 million sub cameras, and Dream version is a combination of 16 million main cameras+20 million sub cameras. Both main cameras use Sony IMX519 sensors. In addition to the different secondary camera sensors and apertures, their ISPs are also different, so the two versions will definitely be different in terms of photography.

The standard version of R15 provides three color combinations of "Snow White, Thermal Red and Star Purple". The SoC is all MediaTek P60 (12nm process, CPU is 4 * 2.0GHz A73+4 * 2.0GHz A53, GPU is Mali-G72MP3).

Screen and system experience

In terms of screen, OPPO R15 adopts the popular Liu Haiping design, with a screen size of 6.28 inches and a resolution of 2280 * 1080. It is believed that many users are very familiar with this screen. The AMOLED Liu Haiping from Samsung has almost become the standard configuration of domestic mobile phones. Although there is a gap between this screen and Samsung's 2K AMOLED, the basic quality is still guaranteed.

In terms of objective test data, under the standard display mode, its color temperature is 7700K, slightly cold, and the maximum brightness is about 400 nits; SRGB color gamut is about 99.4%; In the 104 color standard test, the average DeltaE is 4.3, and the highest DeltaE is 8.8, which is average.

In terms of the system, the machine is equipped with ColorOS operating system, customized based on Android 8.1, and the overall style of ColorOS continues. There is no need to say about localization and functions, and the rights management is also complete. It is relatively used by domestic users, and the UI is more refined than the previous two generations.

In addition to the introduction of support for Liu Haiping, the biggest change is the addition of gesture operation and sliding operation functions, providing users with a variety of modes to choose from. Users can choose the most suitable gesture habit for use. Although it takes a certain amount of time to get used to it, gestures can completely replace the three traditional Diamond keys of Android, but they are still easy to use after getting used to it. In addition, turning off the three Diamond keys can further improve the display area and increase the use efficiency of the screen.

OPPO has designed a full screen multi tasking function for Liu Haiping for horizontal review display. When viewing web pages or videos in horizontal review, the Liu Haiping part does not participate in the display, but provides screen capture/screen recording shortcut keys at the bottom, and common communication applications at the top. For example, SMS, WeChat, and QQ provide dialogue windows in the form of floating windows, which can respond to messages while watching videos. It is quite practical.

Photography and experience

In terms of cameras, the R15 standard version is a combination of 16 million main cameras+5 million sub cameras, while the Dream version is a combination of 16 million main cameras+20 million sub cameras. Sony IMX519 sensors are used for both main cameras. Considering the differences between the secondary camera sensor and ISP, there must be some differences between them in taking photos. However, we currently only have the R15 of P60 version. Let me take a brief look at how the R15 of this standard version performs.

Selfie proof

As one of the most popular mobile phone brands among women in the domestic market, selfie is obviously an area where OPPO is good at, R15 is no exception. The machine adopts a 20 million pixel front self camera and provides a variety of beauty modes. Users can make multi-level adjustments according to their own needs. Acne, skin color and thin face all perform well. In terms of skin beauty effect, it is believed that it can meet the needs of most girls.

Daytime proof sheet

Although the rear dual camera is somewhat different from the dream version in sensor model, the main camera is also the Sony IMX519 sensor with 16 million pixels, which is also the first model equipped with the IMX519 sensor. In terms of daytime proofs, R15 shows the performance that a high pixel sensor should have, with good details, sharp and clear images, and sharp effects. The performance in terms of use experience is OK. The availability of automatic HDR is very high, the shooting is fast, and the background HDR processing capability is available. You don't have to go through the long shooting process of traditional HDR shooting.

Zoom shooting

Although the subphoto does not use the 20 million high pixel solution of the dream version, it still provides a double "zoom" function. The 16 million+5 million combination solution determines that it will be inferior to the dream version solution in absolute details, but it still reaches the available level. After all, the magnification is not large, plus strong sharpening, It is enough for daily microblog and WeChat not to enlarge and cut details.

Night proof sheet

The performance of night and lighting scenes is not as strong as that of daytime, but it is also above the available level. Under normal brightness, the overall performance of the picture is fairly good, but the edge discrimination will decline significantly. The 1.22 μ m unit pixel area is still difficult to make up for the lack of optical anti shake. In the extremely weak light scene, the impact of no optical anti shake is greater. There are obvious large noise spots, and the picture brightness is also slightly insufficient. More work needs to be done to optimize the algorithm.

Performance and running score

In terms of performance, we have previously published a detailed score running article on P60. Please stamp for details《 How about the performance of Helio P60? OPPO R15 score comparison 》。 The dispute over the adoption of MediaTek P60 processors in R15 is still relatively large. After all, MediaTek has not performed well in the past few years. Previously, low-end processors were competitive. However, with Qualcomm paying more attention to the low-end market, Snapdragon 625, Snapdragon 636, and Snapdragon 660 have completely covered the low-end market, making MediaTek's life more difficult. This P60 is positioned in the midrange market. It uses TSMC's 12nm FinFET process and consists of four core Cortex-A73 2.0GHz and four core Cortex-A53 2.0GHz. It supports ARM's HMP technology. It is officially claimed that the performance is 70% higher than that of P23, large games save 25% power, and the overall power saving is 12%. In terms of graphics, MaliG72-MP3 800MHz graphics processor is used, which can support 20:9 full HD display resolution at most.

The performance of P60 in the run score test is still worthy of its positioning, but the run score does not fully represent the actual performance. That is to say, although P60 looks good in the run score, the actual use experience is far less powerful than the run score. There are always some inexplicable slight frame drops in use, such as the occasional frame drop when sliding on the desktop, Although it cannot be ruled out that it is a software optimization problem, it is still slightly inappropriate for a mid tier processor. However, in the past two years, it has been common for MediaTek to have high scores and low abilities, which is not surprising.

Although there are some frame drops in use, users need not worry too much about games such as King Glory. The official targeted optimization is still very stable, and charging will indeed become stronger. However, on the whole, it is recommended that users with certain performance requirements should choose the R15 of Snapdragon 660 with more money. In addition to the differences in performance and optimization, there are some minor differences between the two versions. For example, the Snapdragon 660 version is equipped with Bluetooth 5.0, while the MediaTek P60 version is equipped with Bluetooth 4.2, which may be harmless for most.

Heating during battery life charging

In terms of batteries, the R15 standard is equipped with 3450 mAh lithium ion batteries, which are 50 mAh more than the dream version and 0.2 mm more in thickness, but the difference is not significant. The protective case can be universal.

In terms of endurance, after a 2-hour high-intensity test, the remaining power is 81%, which is a good performance. It is basically similar to the R11s of the previous generation using Snapdragon 660. Surprisingly, during the 4G Internet endurance test, we found that R15 requires to be restarted when replacing the SIM card, which is one of the few models that need to be restarted when replacing the card in 2018. We don't have the R15 of the dream version or other mobile phones that use MediaTek P60, so we can't determine whether it is the reason for MediaTek's base band.

In terms of charging, OPPO's own VOOC flash charge, 5V/4A, is still standard, and the actual charging performance is also very stable. Although it has lasted for several generations, the charging speed is still not inferior to that of current smart phones.

summary

As OPPO's key model in the mainstream consumer market in the first half of the year, R15 has maintained OPPO's good reputation in terms of appearance and quality. There is still not much to be picky about, especially after the addition of gradient colors, R15 is the most beautiful model of OPPO in the past two or three years. It is a favorable propaganda point for the offline market. Appearance design is still a very important aspect of a mobile phone. Even users who pay attention to performance and cost performance will not completely ignore it, let alone those who have higher appearance for mobile phones.

In terms of practicality, for users who simply like OPPO's selfie function, appearance, and even the celebrity endorsement effect, P60 is actually enough. After all, P60 is still better than Snapdragon 625 no matter how poor its performance is. Snapdragon 660 will not have a very significant improvement in experience compared with P60. However, for users who like to play games and have a long mobile phone replacement cycle, the Snapdragon 660 version is more recommended. After all, most software manufacturers, especially game manufacturers, are more attentive to the optimization of Qualcomm's models. In the long run, the Snapdragon 660 version is more stable.
