OPPO mobile phones have always been fashionable and high-quality. In its product layout, the R series does not pursue flagship hardware configuration, but focuses on user experience, thin and light appearance design and photography. It should be said that in the era of excess performance of mobile phones, this meets the selection criteria of many people.

This year, OPPO used the R7 and R7 Plus mobile phones released on May 20 for the flash advertising of "charging for five minutes, talking for two hours". After 153 days, OPPO released the upgraded R7s in a high profile. In fact, there is no need to argue whether the Speed represented by S is a Strengthen or a Super. Let's still talk about the facts. What's the experience of R7s with higher screen share, larger memory and larger battery with a comprehensive experience? Can the fashion quality of OPPO be continued? Can it be called "S"?

"Packaging design, change starts from details"

It has always been believed that packaging design is the first display window of product concept. R7s continues OPPO's packaging design, which is standard and simple, especially the brand green on both sides has become a distinctive feature. After careful observation, it is found that the packaging details of the R7s have changed because of the "All Netcom 4G" logo on the front and both sides. Combined with the label on the back, it can be seen that this is an all Netcom, gold, 4G storage, 32G storage version, and the official price is 2799 yuan.

The functional areas inside the packaging box are clear, the accessories are still abundant, and there are many accessories for conscience, such as earphones. Now many brands have removed earphones to save costs; There is a silicone cover, which is still the perfect fit of the original factory; There are flash charging chargers and special data cables, which will be specially tested later; There are also SIM card pins and warranty cards. In addition, the two fixing clips on the data line can also be used as storage clips in daily life to prevent wires from being too long and tangled.

"Appearance workmanship, reflecting OPPO fashion quality"

First, use a set of data to see the changes after OPPO R7s upgraded to "S". The screen increases by 0.5 to 5.5 inches, and the corresponding three dimensions change to 151.8 * 75.4 * 6.9 mm; The weight increased by 8g to 156g; The proportion of screens increased by 8.5% to 92%; The screen border has narrowed by 14.7% to 2.2mm. From the data, the screen size increases, but the weight and thickness do not change much. According to the official introduction, this is because the internal material of the R7s metal integrated fuselage is changed to magnesium alloy, which achieves both firmness and lightness. From the perspective of use, the thin body is more comfortable to hold.

At present, the front design of mobile phones tends to be the same, but OPPO R7s uses a 2.5D screen with soft edge vision. With AMOLED's screen blackout feature and a large LOGO at the bottom, it is still highly recognizable among cloud computers. The "big white" type openings on the upper front are front camera, earpiece and distance/light sensor from left to right, and a status indicator is hidden on the far left. Because the virtual touch is used, and the screen frame is only 2.2mm, it has a very high proportion of screens.

OPPO R7s adopts the "fiddle elegant arc" design on the side of the fuselage. The official introduction is inspired by the violin. Although the tail has not played the violin, it has also played the guitar. The two have the same thing, that is, the curve design of the neck is borrowed from the connection between the back and the middle frame, so that the transition becomes smooth. Visually, the 2.5D screen's arc edge, middle frame, up and down streamer side, and fiddle arc greatly enrich the visual level in the thickness of 6.9 mm, making the side look thinner and better. At the same time, it also improves the grip, but the connection between the 2.5D screen and the middle frame still has a slight cutting feel. Things often have two sides. On the other hand, it can also enhance confidence, mainly depending on personal feelings.

The buttons on the middle frame have their own placement philosophy. OPPO R7s put the volume key on the left side and the power key on the right side. The feedback of the key is relatively clear. Personally, it is in line with the operating habit of holding the key in a single hand with the right hand. The AND/OR card slot is designed on the upper part of the power key, which is made of all metal materials. The opening and workmanship are exquisite. The secondary card can be inserted into a SIM card or a TF card with a maximum capacity of 128G. Single card users need not worry about the shortage of storage space.

The top of the middle frame is still the noise reducing microphone and headphone interface, and the antenna partition strip is cleverly hidden on the headphone interface to minimize the visual impact on the side. After the earphone is inserted, it can better reflect the ultra-thin body. The antenna partition strip at the bottom and the speaker are symmetrically designed with the charging interface as the central axis, and the dust screen of the speaker is very detailed. R7s has changed the speaker to the bottom, effectively avoiding the impact of the phone lying flat on the desktop on the back speaker volume and sound quality. This is a useful upgrade change.

Fingerprints on the back have always been a headache. The aluminum magnesium alloy back of OPPO R7s adopts surface spraying technology, which has a very delicate touch, and will never leave fingerprints, which can ensure elegant "makeup" at any time. The whole back design is very simple. The middle upper part is a polished LOGO, and the upper left corner is a 13 million pixel camera and flash. There is a ring of slightly protruding metal to protect the camera, effectively preventing the lens from wearing when the phone is placed horizontally.

"Screen effect, just for meeting you at that moment"

OPPO R7s is equipped with 1080P AMOLED screen, 400PPI, and the maximum brightness is about 320 nits. As we all know, AMOLED has richer colors, higher contrast and more power saving features than IPS in the two screen materials. In order to test the screen effect of R7s more intuitively, the tail selects the OnePlus mobile phone that has good relationship with OPPO to compare. This is not too urgent. In fact, there is just a phone 2 on hand, and the IPS-NEO negative liquid crystal technical parameters it uses are also good, just for comparison.

First, the accuracy of the color bar and grayscale tests is good, but the R7s is more saturated in green and blue, and the screen is slightly red, which is more pleasing to the eye and has a slightly better sense of vision.

Then came the saturation test. We selected a test photo with rich colors. It can be seen that both of them perform well in detail, but R7s is more colorful, more bright, and more comfortable in vision.

And then the contrast test. Carefully observe the wall of the building and the clouds in the upper left corner. The R7s AMOLED screen is better.

There is also a contrast picture of visual effects under direct sunlight.

Finally, it is the true restoration test. A sample is selected and the scene restoration test is conducted through the original picture and the effect on the mobile phone. R7s has a wider color gamut and contrast, so it performs well in detail and has a visual sense close to the original film.

"Hardware configuration is not a strong point, but 4G storage ensures smooth flow"

The OPPO R7s All Netcom version is equipped with Qualcomm Snapdragon 616 eight core 64 bit CPU, which is supported by Adreno 405 GPU, 4G storage and 32G storage. From the perspective of main configuration, it does not pursue high-end flagship, which is also due to the positioning of the R series. The specific configuration is as follows.

As mentioned earlier, mobile phones have entered the era of excess performance, and 80% of mobile phone users cannot use 60% of the performance of mobile phones. The Snapdragon 616 processor of R7s uses four 1.5GHz A53 cores and four 1.2GHz A53 cores. After checking the operation of the cores, four small cores are almost fully loaded in the silent state, while only two large cores are sleeping, and the other two are also loaded more than 70%. The score of Anthare is 36950, which is consistent with the performance of this midrange processor.

Running points is the marketing strategy of a manufacturer to play the price performance card. Smooth use is the king. Turn on the GPU presentation mode of OPPO R7s and carry out some daily application operations. The column bar on the screen runs smoothly below the green line, and if it exceeds the green line, it indicates that there is a jam. In general, as long as the network buffer is sufficient, R7s's smoothness performance is commendable.

In fact, I'm still interested in 4G storage compared with running points. With the growing size of APP, more and more applications need to run in the background. Larger memory has more advantages than faster processors to ensure smooth operation. Tail conducted a read and write test on R7s storage and internal storage. The copy speed of 4G storage is 5049.18MB/s, the read speed of 32G internal storage is 148.62MB/s, and the write speed is 96.25MB/s, which is at the middle and high-end level, ensuring a smooth experience in both large-scale 3D game operation and multi task switching.

Large games can reflect the performance of mobile phones laterally. Tail likes to play Wild Racing 8, which is a large racing game with several gigabytes of capacity. The scene changes quickly, there are many light and shadow effects, and there are more collision physics simulations, which is a comprehensive test of mobile phone performance. From the performance of R7s, there is no jam in the game, and the picture effect is at a better level. At the same time, after playing the game for 30 to 40 minutes, R7s is also very hot, and the hardware optimization is still good.

"System UI, high recognition, smooth interaction experience"

At present, all mobile phone manufacturers are trying to jump out of the Android homogenization circle and focus on user experience through in-depth customization systems. Because no matter how good the hardware environment is, it should also operate around the core of the system UI, and the invisible system UI can better reflect the brand characteristics.

OPPO R7s is equipped with ColorOS 2.1 based on Android 5.1. After several version changes, its own characteristics have gradually become distinct. The unique flat and virtual combination effect of desktop icons has no sense of conflict. The default desktop and lock screen wallpaper also give full play to the gorgeous features of AMOLED screens. There are two ways to display the drop-down notification bar. When there is no notification, it is one paragraph. However, when there is a notification, in order to view the notification, it will become two paragraphs. Then, the drop-down bar will display all shortcuts.

The desktop icons of ColorOS 2.1 are all "WYSIWYG", and the folder has ground glass effect. You can enter the editing state by long pressing any icon to move the icon position, organize the folder, uninstall and other operations. The advantage of this method is that it can perform batch processing quickly, but it is not as convenient as dragging the icon directly into the recycle bin when deleting. Each has its advantages and disadvantages.

The settings page is also optimized again. The three major categories of general, sound, and display make it easier to find settings quickly and more efficient. There are many personalized settings for gesture body feel in the settings. Personally, the most useful ones are screen anti false touch, V start flashlight and three finger screen capture. These are used frequently in daily life, and it is convenient to complete actions quickly through gestures.

For mobile phone management software, Tail has always insisted on using the system's own software, and has never used a third party. The security center of ColorOS 2.1 also basically covers the necessary functions. Theme stores, software stores, game centers and even shopping centers, as well as cloud backup address book, SMS and other data, are also very convenient to use. During the experience, twenty or thirty different applications have been installed, including common ones and some financial banks' own APPs. There has not been any incompatibility, and the operation and interaction are smooth.

"Take photos, don't forget that this is OPPO's ace"

The front camera of OPPO R7s is 8 million pixels, F2.4 aperture, 84 degrees wide angle. The characteristic feature of the selfie is the beauty 3.0 function. No specific settings such as skin beauty and big eyes are required, just select the weak, medium and strong effect. In this way, when taking a selfie, you only need to focus on angle and cuteness, and no longer need to worry about how many parameters to adjust a certain beauty, which is definitely a good news for patients with difficulty in selecting. In addition, R7s also supports screen fill lighting. The mobile phone screen will become bright in dark light, which has a certain effect on improving the quality of self portraits. From left to right, the following figure shows the effect of beauty without beauty, beauty 3.0 weak, medium and strong.

The R7s rear camera is equipped with a 13 million pixel camera, which is currently the mainstream mobile phone camera configuration. It is characterized by the comprehensive application of multiple photography auxiliary functions, such as global flash shooting technology, START quick start, PDAF phase focusing, optimal anti shake, and has good performance in focusing speed, quality, and imaging. See the sample below for specific effects.

The photo taking interface is very simple, and the layout is not different, but its additional functions are very rich, and you can download professional modes RAW、 The functions required by fast and slow cameras are also being upgraded and optimized by the authorities.

Next, we will show the effects of several functions through sample analysis and local amplification.

After the ultra clear image quality is turned on, the R7s output photos are increased from 13 million pixels to 26 million pixels, and the image quality is improved by improving the resolution. Of course, during the 2-3 seconds of imaging, you must keep your phone stable. The following figure uses ordinary photography and ultra clear image quality modes to take pictures of residential buildings about 20 meters away, and then zooms in 100% to compare the screenshots. It can be clearly seen that the details of branches under ultra clear image quality are much better than those under ordinary mode.

When HDR is enabled, the imaging time is about 2 seconds, which greatly improves the performance of dark details. The following is a contrast picture of the same backlight scene, ordinary photography and HDR photography. The dark details are restored well.

When using the panorama function, if there is no prompt function when deviating from the axis, the deviation will be automatically pushed over again if it is too large. It is recommended to add a deviation prompt in subsequent optimization. However, the synthesis speed of panoramic photos is very fast, and the synthesis process can hardly be felt. The splicing effect is also good, with a strong sense of impact.

Double exposure is also a fun function. You can take two photos to compose a picture, which can open your mind. The following picture shows the second exposure of posters and cinemas.

The following are some samples of the common mode, and try to select different environmental scenarios to show them.

"VOOC flash charging, charging for five minutes, talking for two hours"

Tail has its own VOOC flash charging set, but by contrast, the R7s flash charging charger has become "smaller". It may be that OPPO has optimized the built-in chip for intelligent identification and current regulation. The output voltage of the charger is conventional 5V, but the output current is 4A. The corresponding interface between the data cable and the battery is 7-pin, 8-contact. In brief, the principle of flash charging is to significantly increase the current and channel through a set of customized equipment to achieve the purpose of rapid charging.

The battery capacity of the R7s has been upgraded to 3070mAh. The daily use of the R7s is very easy. Even if it is heavily used, it can meet the requirements with flash charging. In order to verify the flash charging effect, the tail was tested. The results show that the flash charge is really powerful, and the mobile phone's power was charged from 27% to 91% in only 40 minutes.

On the whole, OPPO R7s is positioned at the middle and high end. Following the R series idea of not pursuing high configuration, but focusing on beauty and photography, Snapdragon 616+4G has sufficient storage performance, plus a series of advantages such as good appearance and workmanship, bright 5.5 inch 2.5D screen, 92% ultra-high screen share, fun and useful photography ability, VOOC's fast flash and so on, which can be said to fully assume the "S" title. More importantly, from the official website, the price difference between R7 and R7s is very small. If you like it, why not choose the S version.
