OPPO R7 is a mobile phone that gathers almost all the popular elements in the market, including a metal body, 2.5D glass, phase focusing, eight core processor, and the indispensable gold body with petty bourgeoisie sentiment. However, compared with those used to show off to friends, R7 is more like a mobile phone that can silently provide you with comprehensive services.

appearance:
R7 is not OPPO's flagship series product, so naturally its specifications are not particularly attractive. Fortunately, OPPO did not discount its workmanship and materials because it is not a flagship machine. A large piece of metal was used on the back of the whole machine, OPPO claims that the material used is magnesium aluminum alloy. We are not really interested in what the material is. When holding R7 in the hand, the frosted metal on the back feels very good, which is quite different from the smooth metal surface of iPhone 6. Therefore, when holding the surface of R7, it will not feel like the iPhone is afraid of falling.
The back edge of the fuselage is curved, OPPO said at the press conference that the design inspiration came from the violin. However, to be honest, there should be few people who have really touched the violin. What you need to know is that the handle of R7's back arc treatment is excellent, so even though there is not much arc feeling on the appearance, it is still obvious to touch with your hand. The metal surface sanding treatment is very resistant to dirt, It is also easy to take care of. Even if it is dirty, take a soft cloth and wipe it with water, and do not need special care in daily use, as long as it is not wasted.
The 2.5D radian screen on the front of the fuselage is a recent popular element. The front OPPO does not put a logo, and the front of the gold and silver models are both white. However, due to the plastic buffer layer around the glass panel, the transition from the frame to the front radian screen is not so natural in visual effect, but fortunately, the feel of drawing into the screen from the edge is still excellent.
As for the body workmanship, R7 performs very well. It is much better than many domestic mobile phones at the same price and focusing on cost performance. It is even better than Jazz Life 8, which is about to be snapped up at a higher price. The whole machine is tight and solid. The buttons and feedback are impeccable, and there is no looseness. The slot and frame fit closely. The antenna partition strip is also very smooth, These are all aspects that OPPO has always done well, and although the body is very thin, its strength is still high.
The top and bottom of the R7 are earphone ports and data cable ports, which are nothing special. However, the power button of the R7 is designed on the left side of the body. It's not a good habit to get it for the first time. After all, most mobile phones now have the power button on the right side.
On the whole, the design of R7 is very stable. There is not much radical design. It takes into account many popular elements. Although the appearance is not as stunning as Samsung S6 series machines, it is quite durable. Among the gold and silver colors, the silver version looks more handsome, and the gold version is more petty bourgeois, regardless of whether the gold version or the silver version, Exquisite workmanship and solid materials are absolutely worthy of every penny consumers spend on this mobile phone.
Screen:
On the official website page of R7, the maximum brightness of the queried screen is 300 nit. In our actual test, when the automatic brightness is turned off and the brightness is manually turned on to the maximum, the screen can reach more than 320 nit, which has exceeded the nominal value. Although this number does not seem high, the contrast of the AMOLED screen is very high, and its reflectivity to external light is relatively low, So the R7 screen can be used outdoors even in strong sunlight.
With the continuous progress of AMOLED screens, the problem of color restoration distortion, which was criticized by AMOLED in the past, has been greatly improved. The top AMOLED screens represented by Samsung are more accurate in color restoration accuracy than almost all LCD screens on the market. Although we don't know where the AMOLED screen of R7 comes from, the AMOLED screen of R7 also follows the trend of focusing on the accuracy of color restoration of mobile phone screens, and does not blindly improve the color saturation in pursuit of gorgeous colors. It does a good job of restoring the true colors of pictures, and there is no problem with the visual angle, Due to the characteristics of the AMOLED screen, there will be no light leakage when displaying black, and the overall saturation of blue is relatively high, so the white display tends to be slightly cooler.
System:
This time, surprisingly, OPPO did not equip R7 with the latest Android 5.0 system, but continued to use the Android 4.4.4 system, ColorOS 2.1 seems to have limited UI and function upgrades. The focus of the R7 system this time is to improve the overall running speed. Numerous precedents show that the MT6752 processor can also provide excellent smoothness when paired with a 1080p screen. As for the overall use experience, it largely depends on the manufacturer's optimization of the system.
The system optimization of R7 is really very good. After a period of use, I feel that R7 is even better than some mobile phones using Android 5.0 in terms of fluency. Elegant and exquisite transition animations run all the time in full frames, and the system is not stuck. The third-party applications that are easy to get stuck, such as Weibo client and Taobao client, are also smooth, Switching between applications is also fast, which is the advantage of RAM.
As for the specific functionality of the system, R7 has two very practical functions: double click on the bright screen and double click on the HOME key to lock the screen. Although it sounds trivial, R7 sets the power key on the left side of the body rather than the normal way, so it is not natural to use the index finger to press the key to lock the screen when holding it in the right hand. With these two functions, it is much more elegant to use, and R7 is also anti touch, So don't worry about waking up your phone in your pocket. There is still a one handed mode that is not very practical. Now many people must be trained to operate a 5-inch machine with one hand.
In a word, although the system has no special functions, it is smooth and practical, and has all the functions you want.
Performance:
From the current perspective, the strength of MT6752 has been well confirmed. This year, Qualcomm's mid-range processors are very weak, so from the actual user experience, there is no need to believe in Qualcomm. MT6752 has strong performance, low power consumption and is also very affordable, so it is very cost-effective for manufacturers and users to use 6752.
The performance scores of R7 are as above. If you want to see more performance comparisons of mobile phones, you can move to our Score database 。
In addition, I don't know whether the 6752 has been adjusted or how. Neither the vivo X5 Pro we recently contacted nor the 6752 in R7 will automatically "overclock", The CPU sticks to the maximum dominant frequency limit of 1.7GHz, and will not increase the frequency to 1.86GHz to obtain additional performance when turning on 1~2 cores like the U3 produced by OPPO before. When the single core 1.7GHz is not enough, R7 will choose to turn on 4~6 cores. When facing heavy task processing, it is natural that all 8 cores are turned on. As for heating and frequency reduction, R7 does not. Even after 8 cores are fully opened for a period of time in a row, the fuselage can maintain the highest frequency of 1.7GHz even when the fuselage is warm. Considering that the performance gap caused by the 0.16GHz frequency difference in daily life is insignificant, it is not worth worrying about the performance of R7. It is the most important thing to be smooth anyway.
Endurance:
The R7 is only equipped with a 2300mAh battery, which makes us worried about its endurance. However, let's have a test of its endurance.
Our endurance test process is as follows:
The fixed screen brightness is 200nit. First run the large game NBA 2K15 for 30 minutes, then surf the Internet for 30 minutes with Wi Fi/4G, then watch high-definition video for 30 minutes, and finally turn off the screen for 30 minutes to play music.
The final remaining power is 56%, which is good for the 2320 mAh battery capacity. Under normal use, the endurance is basically the same as Samsung's Galaxy S6 Edge, R7 is slightly better. There is no problem in using this ability for a whole day. If a black interface theme is selected according to the characteristics of the AMOLED screen, the endurance performance may be better. However, it is basically the limit if you do not charge for one day and a half.
Of course, R7 is also equipped with VOOC flash charge. The charging time measured from 1% to 100% is less than 1 hour, especially when the power is low, when the flash charge charger is plugged in, it can charge nearly 20% of the power in ten minutes. If the mobile phone is in urgent need, it is very helpful. In terms of the overall output power, OPPO's VOOC flash charge is larger than Qualcomm's QuickCharge 2.0, and the charging speed is naturally faster. VOOC flash charge is still one of our favorite features on OPPO mobile phones.
Camera:
The R7 camera uses the same phase focusing technology as the iPhone 6 and Samsung Galaxy S6 cameras, which focus by detecting the distance between objects. It is the second domestic brand mobile phone that uses phase focusing technology after the vivo X5 Pro, The focusing speed of R7 is about the same as that of Samsung Galaxy S6 Edge, whose price is more than twice that of R7. After clicking the screen, you can focus and measure light in one step. If you are not satisfied with the measurement, you can also slide up and down to adjust the exposure value, which is very comfortable to use.
In addition, although R7 does not have a shutter key that can quickly start the camera on the hardware, the R7 system is equipped with the rest screen gesture function. As long as this function is enabled, you can directly start the camera by drawing a circle on the screen when the screen is closed. As for the shape of the circle, there is no special requirement, and the drawing can also be triggered quickly, The startup speed is OK (about 2 seconds from the time when the hand touches the screen to the time when the camera starts). It is very useful to take out the pocket to capture life (the picture above is GIF, which is large).
The effect of R7 in daytime photography is very excellent. The color is full but not too bright, the exposure is appropriate, the noise control is good, the degree of sharpening is not high, the details are abundant and natural, the contrast is relatively high, so the picture has a good sense of hierarchy.
R7 imaging at night is not as good as daytime imaging. When the light is poor, There is no problem with the color and brightness of the R7 sample image, and the noise control is also good, but the detail performance has dropped significantly compared with that in the daytime, which once gave us the illusion of R7 out of focus. However, if we zoom in to see the picture, we can still find that R7 is simply lost in detail, and there is no light measurement error, white balance deviation, out of focus, etc, Therefore, the detailed performance of dim light photography should be an aspect that OPPO needs to improve in the future.
As for R7's HDR function, when it is turned on, there is a certain probability that it will improve the overall color saturation of the picture, making the picture as a whole very bright. But in most cases, the HDR synthesis effect is very good, the light and shade distribution of the picture is very natural, the edge of the object will not have halos, and the overall image quality is very good. However, we hope OPPO can add an automatic HDR option in the future, It will be easier to take photos in this way.
Of course, there is also an ultra clear mode. We are not unfamiliar with OPPO's ultra clear mode. We can obtain a photo of nearly 50 million pixels through multiple compositing. In this mode, the photo details will be slightly better than the normal mode, and the picture will look a little soft, not as good as the ultra clear mode of OPPO U3 we have previously contacted. I don't know why.
Summary:
Again, R7 meets all our expectations for OPPO mobile phones: excellent workmanship, excellent system fluency and excellent photography. In the eyes of many parameter parties, R7 should lack highlights among mobile phones at the same price. However, R7 is not a mobile phone born for parameter parties. It focuses on quality and grade. If you put R7 in the Samsung Galaxy S5 Among the previous generation flagship of international brands such as HTC ONE M8 and LG G3, R7 is on a par with them in terms of performance. The metal body makes R7 feel and grade much higher than those of S5 and G3, which use plastic body. The excellent photo taking effect and thin body make it particularly attractive to ONE M8.
Returning to the opening sentence, R7 integrates almost all the popular elements on the market at present, puts them all into a well made fuselage, and then makes some upgrades that can improve the actual use experience but cannot be reflected in the parameter table in terms of daily use fluency and photography effect, The addition of VOOC flash charge makes charging very comfortable. R7 is not a mobile phone used to show off to your friends. It is a mobile phone that can silently serve you everyday and give you a good use experience. For buyers who pursue the word "easy to use", this is enough.
