▼ What impressed me most about the OPPO brand was the very classic slogan "five minutes for charging, two hours for talking", which even became a very popular online language at that time, and the versions that were tampered with by many netizens emerged in endlessly. But when it comes to in-depth understanding of the OPPO brand, we should start with its star model R7. My wife used R7 all the time before, and later changed it to R7S. Whether from the manufacturing process, its VOOC flash charging technology, and its powerful self timer function, OPPO's mobile phone is a very attractive smart phone, and its appearance has always been good, So its excellent performance of both internal and external training is also highly praised in the market, and it also left me a very good impression. This year, OPPO also took advantage of R7 to launch its upgraded work R9, which has raised its appearance to a new height. It focuses on the extremely thin fashion line, and also gathers fingerprints to quickly unlock VOOC flash charge, 16 megapixel selfie beauty 4.0 and other outstanding skills, so many kids are really hot, but don't worry. Come with me to see more about R9, and it's not too late to make a decision.



▼ As a mobile phone for young people, OPPO R9's outer packing box adopts pure white color, which is simple and fashionable. Except for the logo logo of silver, there is basically no extra decoration on the whole box.

▼ Open the packing box, and the inside is displayed in multiple layers. The top layer is the mobile phone, the middle layer is the transparent mobile phone case+pin, and the lower layer is the power supply and headset. Each has its own place and is in order.

▼ The accessories accompanying R9 include split power supply, earphone, transparent mobile phone case, clip and instructions.

▼ When the mobile phone is handed over, a tempering film has been pasted on the screen, which should be available at the factory. Although it is a small detail, it is enough to see the intention of the manufacturer. In terms of appearance, although the shadow of the previous work can be seen from the body of R9, the overall appearance of R9 is more harmonious, and the corners are more rounded.

▼ On the back of the fuselage, compared with the R7S, it has also made further processing. It adopts the same nano injection signal strip design as the iPhone 6S, but the color selection is more coordinated with the main tone. The back shell and side frame adopt the design of integrated molding, and the material is 6-series aluminum magnesium silicon alloy CNC、 It is made by dozens of processes, such as grinding, sandblasting, anodizing, and radium carving. The handle is more delicate and even, and it will not be too slippery or touch.

▼ OPPO R9 uses a 5.5 inch 1080P display screen, The body size is 151.8mm × 74.3mm × 6.6mm, and the weight is 145g. The most important thing is that its screen frame is only 1.66mm, accounting for 77.68% of the screen. It can be said that it is the phone with the narrowest frame I have ever used. The overall size of the R9 is very well controlled. It has a 5.5 inch screen, but is the same size as a typical 5 inch mobile phone. Boys can easily operate it with one hand. Even girls, it is not too difficult.




▼ Compared with the previous work of R series, R9 has made great efforts to take a selfie. It is equipped with a new customized 5P lens with 16 million pixels in front, which improves the sensitivity and tolerance of the camera to light, making the picture quality clearer and brighter, and the dark part has better performance. The aperture is even higher than 2.0. Every shot is the most beautiful one. It is estimated that many beauty lovers will be thrilled!

▼ In terms of rear camera, R9 failed to use the flagship SONY IMX298 sensor like R9 Plus, but fortunately they both With the use of PDAF phase focusing, you can accurately identify the rapid focusing. At the same time, it is equipped with the optimized anti shake 2.0 technology, which can make it easy for non professionals to take high-quality photos. But in terms of design, The rear camera of R9 is protruding, which will inevitably cause scratches in daily use.

▼ OPPO R9 uses an elliptical solid key at the bottom of the screen, which is the LOGO position of R7S. Of course, it is not just a key, but also the fingerprint identification of R9 Zirconium gem is used as the fingerprint key material, which is as warm as jade, 8.5 Mohs hardness, close to 9 Mohs hardness of sapphire, Durable, with higher dielectric constant than sapphire, higher signal strength and more sensitive identification.

▼ The right side of the phone is distributed with the power button and card slot, and the left side is the volume adjustment button of the phone. After a period of use, it was found that every key position of R9 was carefully considered, and our fingers were just placed on the keys when operating with one hand, which greatly facilitated our operation. In addition, if you look carefully at the mobile phone, you will find that there is always a luminous waist line on the side of the R9, which is called the condensing waist line. The inspiration comes from the lofty snow mountain. No matter how you turn the mobile phone, you will find that the light always stays on that waist line.


▼ The card slot on the side of the body of OPPO R9 still uses the conventional smart card slot design. Slot 1 is a Nano SIM card, while slot 2 uses a variable design. You can choose another card Nano SIM card to realize dual card and dual standby. If you are a large space user, the 64G that comes with the fuselage is not enough for you to use You can choose to insert a TF card to expand your storage space, which can support a maximum of 128GB expansion. Of course, you can only stay with a single card. How to choose depends on your own needs. In addition, in terms of network, OPPO R9 is divided into two versions for users to choose: mobile version and all Netcom version. What I introduce here is the all Netcom version. But when it comes to all Netcom, R9 is not really all Netcom, because it can only support one card for 4G network and the other for 2G network at the same time, and it does not support the use of two telecom cards at the same time.

▼ In terms of video recording, OPPO R9's front and rear cameras support 30 1080P/720P high-definition video recording per second. For this reason, R9 also designed a Maikong on the top of the phone for recording audio.

▼ A row of 7-hole speakers, data/charging interfaces, noise reduction microphones and 3.5mm standard headphone connector.



▼ At present, fingerprint unlocking is no longer a black technology. Most newly released models above the middle end will be equipped with this function, even some entry-level models also have this function. Therefore, it is not a big deal to have this function, but it is really easy to use and fast to unlock. Compared with most mobile phones equipped with fingerprint unlocking function, R9 places fingerprint identification on the front of the phone and integrates it with the HOME key. This has the advantage that it can be unlocked at the fastest speed. The fingerprint identification speed of R9 is up to 0.2 seconds, which is even faster than the iPhone 6s in actual comparison.

▼ R9 fingerprint recognition supports five sets of fingerprints, that is, you can enter one hand into it. Of course, if you have more secrets, you can choose to use your little toe to identify. In addition, R9 fingerprint unlocking can also be applied to software to add some more important or private software to the safe, such as QQ, WeChat, Alipay, Taobao, etc., so that personal information and property security can be guaranteed.

▼ Fingerprint is a password that needs no memory. It is not only unique but also safe, because it is unique to you. Fingerprint identification of R9 It supports Alipay and WeChat fingerprint payment. When you pay, you can do it with one click. You will never have to enter the long and hard to remember password again, and you will act like a force in front of your sister. I must give full marks.

▼ Without my fingerprint, my wife will never peek at my WeChat again! (Ah, wife, don't beat my ears. I just write a review. There is really no secret in WeChat! ）

▼ Let's talk about OPPO VOOC flash charging technology has always been its pride. Through the promotion of previous generations of products, OPPO's flash charging technology has been deeply rooted in the hearts of the people and won unanimous praise in the market. Now in the field of smart phones, the short battery life has always been a barrier that is difficult to overcome. Basically, the best case is that it needs to be charged once every two days. Most of them are charged once a day, or even more than one day. So since we can't solve the battery problem for the time being, we can only go to another way to solve the charging problem. After three years of research and development, and two years of market verification, VOOC flash charging creatively solves the problem of smartphone endurance to some extent, "charging for 5 minutes, talking for 2 hours ” This is not simply a slogan, it has become a fact.

▼ Be quick and safe. The working voltage of VOOC flash charging is the standard 5V charging voltage commonly used by the mobile phone system, which is acceptable and safe for the mobile phone system, At the same time, the VOOC flash charge adopts a new topology structure, which is more efficient, and the temperature of the mobile phone is lower when charging. Let's take a closer look at the power supply of R9. The output is 5V-4A, while the commonly used mobile phone chargers are 5V-1.5A or 2A. Then the power output of R9 chargers is twice or more than them. In this case, it can also ensure the security of mobile phone charging, which is really a very good technology.

▼ According to the actual measurement, the power of R9 in the initial charging state is 3%, and after 20 minutes, the power reaches 46%, while it only takes 1 hour and 5 minutes for the power to reach 100%, which is much faster than my normal mobile phone. It seems that "charging for 5 minutes, talking for 2 hours" really deserves its reputation.



▼ We have previously introduced some hardware parameters of OPPO R9, so let's experience the R9 system together! R9 system adopts OPPO deep customization Color OS 3.0, in a customized system, Color OS is also one of the better systems. It is on a par with MIUI Color OS 3.0 breaks through the previous design style, and the entire interface is more simple and intuitive.

▼ In terms of the main interface, R9 has re optimized the entire layout, including icons, fonts, colors, etc., to make it more unified and coordinated. The system has removed many of the original things of ColorOS 2.1, and even the restart button is missing. The purpose is really puzzling.

▼ The shortcut menu can be called out through the pull-down mode, and the left and right page turning is the notification interface.

▼ The left function key of OPPO R9 can view the background running programs and memory utilization rate, where users can easily end useless processes.

▼ R9 supports gesture somatosensory function. We can set different gestures to perform different tasks, which improves the work efficiency to a certain extent, and gesture operation is more compelling. For example, for a screen capture function we often use, we usually press the power key and volume down key at the same time, but with gesture function, We can use three fingers to slide on the screen for screen capture. Is it faster and more dazzling? In addition, you can also call out the long screenshot mode by long pressing the power key and the volume increase key.

▼ Although OPPO R9 controls the volume of the whole machine properly, for some friends with small hands, especially girls, the one handed operation may not be so smooth sometimes, so R9 has designed a one handed operation mode, which can be activated by sliding the screen from the bottom left to the bottom right towards the middle. In this way, the one handed operation will become easier.

▼ Since the launch of the iPhone 4S, another product that has entered people's lives with it is siri, which can be said to be The arrival of Siri is very important for Apple. To a certain extent, it has greatly facilitated users' operation on mobile phones. Most Apple users are probably used to chatting with Siri every day. For Android users, although there is no siri, they should have tried many voice assistants with similar functions Color OS 3.0 system has its own voice assistant function, which can be activated by pressing the HOME key for a long time. It can carry out simple chat conversations with you, help you open the applications you want to open, and help you tell jokes, check weather, stocks and other information.



▼ As we all know, OPPO is different from Xiaomi. From beginning to end, OPPO's flash charge and selfie functions have been publicized to the outside world. It has been attracting users with its features. What about the performance of R9 as a mid tier mobile phone product? Although running points does not mean everything, it is also the most intuitive and fastest way to understand the performance of mobile phones. We first tested it with Anthare and got a score of 51093. At present, this score is not high, like Xiaomi 5, which got nearly 140000 points. In general, R9's score is above average, which means that R9 can cope with most applications and games. Of course, especially large 3D games are expected to be difficult.

▼ The following is the test result given by NenaMark2, passed Simulate the game like picture, and finally give the average real-time frame rate of 59.8 fps, which is also above the average level.

▼ Then Vellamo's test data, Vellamo as a professional Authoritative software for evaluating browser performance on Android devices, It provides a comprehensive benchmark for the performance and stability of browsers through network, script, rendering, user experience and other test items. The test results of three items, including browser, metal and multi-core, are relatively excellent.



▼ OPPO R9 uses MediaTek MT6755 eight core processor, 4GB RAM+64GB ROM, and ColorOS 3.0 system developed based on Android 5.1, which makes the system more compact and saves memory. Although R9 adopts The MT6755 processor is really hard to avoid. Compared with Qualcomm Snapdragon's processor is really poor, However, the actual performance is fairly good. In the initial state of power on, R9 has 2.82G of memory available, which should be more.

▼ R9 CPU usage when playing 1080P HD video.

▼ R9 CPU usage when playing large games.

▼《 NBA2K15 》1.7G is a very large game on mobile phones.

▼ From the above test chart group, we can see that the CPU utilization rate of OPPO R9 is about 60% when playing 1080P HD video, but the eight cores are only four cores, and not full speed. While playing large games, the CPU frequency reached its peak, but only three eight cores were turned on, and the occupancy rate was between 50% and 80%. After the data is finished, let's do something practical. I chose a special test The video and audio test samples of R9 are used to make a comprehensive assessment of the audio and video playback ability of R9.

▼ First of all, OPPO R9 does not support AC3, EAC3 and DTS audio coding because of copyright issues. So if you need to, you can download other playback software to play.

▼ In the format support, my test samples basically cover all the mainstream audio and video formats in the market. Through the test, R9 does not support videos in rmvb, vob, tp and evo formats, and does not support audio formats in vqf, dts, and ac3, and does not support reading the cue list. However, it is a bit difficult for R9 to test the mobile phone with the standard of testing high-definition players. However, most of the videos we play on the mobile phone are 720P MP4 or MKV files. After testing, R9 has very high support for these common videos, and there is no problem in playing them. Therefore, R9 can definitely meet the daily local viewing needs of most users.

▼ However, the test results of Anthare video evaluation software are also not very satisfactory. Only 14 of the 30 test samples are perfectly supported, 15 do not support, and 1 does not fully support. But in fact, this test result is understandable, because there are many 2K and 4K movie sources in the sample of rabbit video evaluation, and R9 naturally does not support it.

▼ In the game test, I selected several large games with large size and high requirements for mobile phone hardware, respectively 728M《 Street Fighter 4 》, 1.47G real-time combat game Ju Bang Implosion, and 1.7G NBA 2K15.

▼ After testing, the three large-scale stand-alone games all run perfectly without any stagnation. Friends who like to play large-scale games on their mobile phones but worry that R9 can't afford it can now start with confidence and boldness.



▼ While playing the game, I also measured the temperature of R9. This is the data tested immediately after playing Street Fighter 4 for an hour. The maximum temperature of the fuselage is 39.5 ℃. I am very satisfied with this result. I used two mobile phones of other brands between them, which can really be called "winter must-have". Let alone playing games, you have been online for an hour in a row, and the mobile phones are already hot. They definitely have the potential to be hand warmers. When I play the game, R9 feels a little warm at most. In addition, the metal body has good heat dissipation. As long as I leave the hand for a while, the body becomes cool immediately.



▼ People who know OPPO know that it has always focused on and recommended the selfie function. Now, especially on R9, it has pushed selfie to a new height, with 13 million in the rear and 16 million in the front. This shows the importance of selfie. In addition, the beauty 4.0 with R9 really makes those beautiful women who love taking selfies excited.

▼ OPPO R9 supports multiple shooting modes, professional mode and ultra clear image quality. In addition, there are multiple filters for users to choose.

▼ In self portrait beauty, it supports level 7 beauty. The lower the number, the whiter the image will be. The higher the number, the more rosy the image will be.

▼ My Xiaogongju took a five consecutive shot first, but today I was not in a beautiful mood and a little expressionless.

▼ I showed my face with my little lover in my previous life. The effect of beauty is really good, and the skin is clean enough.

▼ There is no comparison. It seems that the persuasiveness is not very strong. I will sacrifice myself to make a comparison before and after beauty. You should see the gap!

▼ The 13 million pixel camera behind R9 has good comprehensive quality, plus fast PDAF phase focusing, the imaging quality is satisfactory.




▼ The close-up photography also has an excellent performance, and the details are in place.

▼ It also performs well in the indoor lighting environment.


▼ In addition to the above factors, the screen performance should also account for a large proportion of the key points that users care about when buying mobile phones. With the upgrading of mobile phones, the screen of mobile phones is not only getting bigger and bigger, but also the resolution is getting higher and higher. The 720P, which used to be the mainstream, is far from satisfying users' critical vision. 2K 4K has come into our life, but the mainstream screen is still 1080P. R9 uses a 5.5 inch 1080P resolution SUPER AMOLED high-definition screen. The display effect is exquisite, the viewing angle is wide, and the pixel density is as high as 401ppi Watching movies and playing games can bring users great visual enjoyment.

▼ The visual angle is very good.

▼ We can experience the screen display ability of OPPO R9 through the following group of live photos displayed on the screen. The color is more realistic, the contrast is higher, and every detail can be fully restored.

After more than a week's trial, let's talk about some of my personal views first! OPPO R9 focuses on fashion selling points, which are very pleasing to young people in all aspects, including production process, appearance design, internal VOOC flash charge, 16 million front camera, Beauty 4.0, and fingerprint unlocking and expansion to the field of fingerprint payment. Let R9 go deep into every moment of daily life. Color OS 3.0 makes the whole system interface more pure and simple. 4G large memory can meet our various application needs. 64G storage space is basically enough. The price of 2799 is not high at present. It is in a reasonable price range. In general, OPPO R9 is a mobile phone worth buying. To sum up R9, we can quote a sentence, that is, "You can rely on your face, but you have to rely on your talent."
