『  Preface 』

——————————————————————————————————————————

The OPPO of "charging for five minutes, talking for two hours" came out again Main self timer function New product R9, flash charge and selfie are still strong points. When it comes to R9, the price is 2799, which may be the flagship price compared with other brands, but OPPO should belong to the mid tier series. It can also be seen from the configuration that it is not OPPO's flagship model (the flagship should be OPPO FIND9). The target group of R9 is very clear. Female friends who like to take selfies generally do not pay too much attention to configuration, nor do they pay much attention to the word "cost performance". They may be more concerned about the phone appearance and photography, which is the main feature of R9. In addition to taking selfies and flash charging, what is the attraction of R9? This is something we need to know?

『   Unpacking&Details   』

——————————————————————————————————————————

The following figure shows that the overall packaging of the OPPO R9 provided by Lei Feng on trial has changed from the traditional green and white matching of OPPO to the pure white matching.

It should be noted that this model is OPPO R9 tm version, which supports mobile and Unicom 4G; R9m is the true All Netcom version that supports telecommunications.

R9 is available in gold and rose gold. This is the gold version; Standard 64G memory and TF card expansion are also supported. Don't worry about storage 。

The following is the R9 family portrait: In addition to the R9 host, it is also equipped with a VOOC flash charge package, and a headset and a transparent water drop cover, which are very considerate.

Product details:

R9 is equipped with 5V 4A fast charging head and 7pin fast charging line as standard, Input current than Market support 1A/ 2A charging head is much higher This is also the most important kit for VOOC flash charging.

The size of the R9 charging head and the thickness of the charging line are both larger than those of the ordinary charging kit (the need to transmit more current). Although the size has increased, the R9 is still compatible with the ordinary Micro USB charging line, compatibility This is better than the USB Type-C interface.

Look at the R9 main body

Someone said, "R9 looks like Samsung on the front and Apple on the back? "Let's see the details.

First impression of positive perception: clean , which is mainly due to Super narrow edge And hidden underneath Breathing light button Design, continue to look down.

The top is designed with symmetrical openings. On the left side of the earpiece is the sensor, and on the right side is the legendary front 1600W camera. Careful friends will find that the front of the R9 has a film, which is very considerate. (Non tempered film, scratch after long-term use)

Below is the oval Home button with fingerprint identification. The "Select"/"Return" buttons on the left and right sides of Home hide the breath lights, so the screen off state maintains a positive and fresh look. However, the breath lights are slightly less bright under strong light, and there is no problem at night.

The top is a microphone MIC hole, and the left and right sides of the charging port at the bottom are speakers and 3.5MM headphone holes, which are out of order compared with Apple. However, what is worth complaining about is the left speaker. When playing games or watching movies on the horizontal screen, the hand will block parts, affecting the sound.

The side is a good place for R9, and the fuselage is relatively thin, with a thickness of 6.5mm; The left side of the body is the volume key, and the right side is the SIM card slot and the power on key. It is comfortable to hold.

The side of R9 adopts the design of "condensing waist line", which inclines inward to better fit the part of human hands. The actual feeling is good.

It is not surprising that there is a circle of bright ribbon cut by CNC on the side, which is available on R7 and many models; But fortunately, the concave design of the "condensation waist line" makes the R9 not have the obvious cutting feel of R7, Good grip.

R9 tm supports the combination of a TF card+a NANO SIM card, or a NANO SIM card+a micro SIM card at the same time, but you can only choose one of two options: dual card dual standby or single card single standby+TF card expansion.

Looking at the back of the fuselage, it seems that the back is also a common three-stage design, and also has white plastic strips. At first glance, it does look like an iPhone, but in fact, R9 is more refined. The three sections on the back of R9 are all metal, and metal accounts for a high proportion. At present Many mobile phones include IPhones are designed with top and bottom plastic+middle metal, In addition, the R9 has only one plastic strip, rather than the design of the iPhone, so it is relatively more refined. The frosting treatment makes it feel good.

In the upper part, 1600W pixel+monochrome warm flash is used, the lens is slightly prominent, and the antenna strip is curved along the camera. Personally, it is more beautiful than the iPhone 6s; However, the camera of R9 is not equipped with light protection and dual color temperature light, which is a pity.

The lower half also uses a strip type antenna plastic strip, which is rendered in golden yellow, matching the overall body color, not abrupt.

Appearance summary:

The front appearance design, grip feeling and detail handling of R9 are undoubtedly worthy of recognition, especially with the super narrow frame and hidden breathing lamp, which makes the front very pure and the effect shocking; However, the opening setting of R9 speaker is not reasonable, and the rear camera does not have light protection and dual color temperature flash, which is a pity. In a word, the appearance of R9 is a bonus item.

『 Screen&Black Edge 』

_____________________________________________________________________________________________________

The display effect of the mobile phone has a lot to do with the screen and the black edge. No matter how beautiful the screen is, the big black edge can be destroyed.

Because R9 mainly focuses on thin and light experience, Samsung AMOLED is the only choice on the screen. Why do you say that?

Samsung AMOLED features:

have low Power consumption, self illumination, large color range ， Color reversibility/ High contrast And other advantages. The most important thing is that Since the backlight panel is cancelled The thickness of the screen is thinner, but it is difficult to achieve thin and light IPS screens. Therefore, manufacturers of thin and light mobile phones such as Jinli and OPPO tend to use AMOLED screens, which may also be the only choice. Of course Samsung AMOLED In the early stage, the screen was cold (blue), and the screen burning rate was high Will R9 also have such problems?

Next, take a look at the actual measurement on the screen:

Color display:

In terms of color display, Samsung AMOLED screen shows its advantages. Compared with the iPhone screen of IPS, the color display of R9 is really more beautiful, green, yellow, blue and flattering. (The following photos are real photos, and some colors are different from the actual ones)

The following is a black and white contrast ladder diagram. You can see another advantage of the AMOLED screen, which is pure blackness. Pay attention to the black part.

Viewing angle:

This AMOLED can The visual angle is also good ， Not from the side Obvious color cast is found.

Light leakage and blackness:

Since AMOLED is self luminous, black means it does not emit light, so in case of full black, there is no light leakage and it is quite pure; Compared with the IPS screen of the iPhone, when it is completely black, you can basically see dark gray. (The photo is for the camera's sake, but the actual appearance of the iPhone is dark gray)

The following is the display effect of the pure black picture taken before.

The following is a comparison of live photos. In the photos, the sky is bluer and more colorful with more details.

Similarly, R9's green performance is more colorful, and it looks green.

Blue Sea

The white and blue of R9 in the photo will be more beautiful, the model will be more white and the contrast will be higher.

Daytime display:

Night display effect:

Through observation, it is found that the display effect of this Samsung 1080P AMOLED screen is really excellent.

True ultra narrow borders:

Whether the mobile phone is beautiful or not, the screen display is the key. The screen is OK, and the black border is the problem. At present, many models are promoting "ID without border" and "beauty of rest screen". However, when you light up the screen, the big black border makes you feel "disgusting". R9 meets my expectation of a narrow border, inside and outside 1.66mm Narrow border, especially when watching videos and browsing web pages.

Summary:

The 1080P Samsung AMOLED screen of R9 has outstanding display effect, high color rendition, good blackness and visual angle, and the screen tuning is in place. Compared with the iPhone, it is slightly bluish (less influential), and no yellow screen problem is found. With the 1.66mm narrow edge, the overall display appearance can be described as "excellent", so In terms of current usage The display of R9 impressed me very much.

Operation Experience 1/2 - "Fingerprint Identification"

______________________________________________________________________

Good system experience is "fast and stable", how is R9 doing 。

0.2 second fingerprint identification: how fast is it?

Unlocking the bright screen is probably the most common action we do every day. The speed of natural unlocking is also one of the most intuitive experiences. On the way of pursuing fast, R9 can be said to have played its utmost role in fingerprint, with 0.2 second flash unlocking.

Unlock speed PK iphone6

For fingerprint recognition, it is not enough to be fast. Only on the premise of ensuring high accuracy of fingerprint recognition can we talk fast. The fingerprint recognition rate of R9 is also very high, which may be related to the relatively large fingerprint recognition area and the fingerprint system of "the more you use, the smarter". In addition to "wet hand unlocking", under the current personal use condition The fingerprint identification of R9 is very satisfactory . (Of course, the stability of long-term use must pass the test of time.)

Operation experience 2/2 ——System UI   』

______________________________________________________________________

R9 uses ColorOS 3.0. Compared with the previous generation of cool plug-ins, Made large-scale cuts, ColorOS  three This time, it is lightweight and simple. Of course, the fluency has also been greatly improved. However, it is also obvious to imitate IOS in UI details.

Power on - networking - account creation - activation completed.

After activation, fingerprints can be added, and multiple fingerprints can be set. Each fingerprint acquisition requires 10 times of pressing.

After entering the UI, you will find that the entire interface is very similar to IOS. Of course, you can also change the theme. However, this default IOS theme does attract many people's contempt, but It's really quick for IOS users to get started.

The top pull-down call out shortcut setting button has many functions; Slide up at the bottom to turn on the camera.

System settings at a glance: It is also very similar to the iPhone, so the details of this set of UI imitate IOS very clearly.

Features:

The black screen gesture is a convenient and fast start software. The measured trigger success rate is high and easy to use.

The localization optimization of R9 is good. For example, the classification management of files and the location and number search of mobile yellow pages are convenient to use.

In terms of making calls and receiving SMS messages, dialing is simplified, SMS messages are also automatically classified, and the use efficiency is improved.

If the system wants to maintain stability, it is not easy to get stuck. Cleaning garbage and allocating memory are the key. R9's one click memory cleaning+garbage cleaning function is very practical.

Of course, the most frequently used UI is the "theme store", "game center" and "software center" built in OPPO, which are basically sufficient.

Of course, some BUGs still need to be mentioned, such as in the "game store" Some large 3D games cannot be downloaded and installed The new speed is not fast enough. Of course, these can be supplemented by downloading third-party apps, such as the common "pea pods" and "91 assistants".

UI summary:

ColorOS 3.0 By reducing plug-ins and animation scenes and cooperating with 4G storage, the system is smooth in use. The localization optimization is meticulous, simple and easy to use. Bugs still exist, but the overall situation is good What's worth complaining about The trace of imitating IOS is too obvious. I hope OPPO can have its own UI style in the future.

『 Take photos 』 : How awesome is it?

______________________________________________________________________

Camera parameters:

Front camera: 16 million pixel lens (F2.0 aperture), 5P lens, 78.1 ° wide angle, light filling function, built-in beauty 4.0.

Rear lens: 13 million lens (aperture F2.2), supporting contrast focusing+PDAF phase focusing, single LED flash light, which can quickly "flash".

Maybe you are the same as me. When you hear the front 1600W+the rear 1300W, you think you read or heard the wrong thing. Of course, this time OPPO R9 is the main "extreme selfie", so it is not unusual to have the front 1600W. The front 1600W+2.0 aperture+night fill light+ Beauty 4.0 will bring different experiences to beautiful women who love taking selfies. Let's witness it together.

Capture interface: although Color OS 3.0 operating system adopts New design, but the photo and camera interfaces have not changed, Same as R7 Similar to the "apple style", it has its own special photography effect.

Rich photographing functions: Time delay photography (ten seconds and one second), video photography (1080P/720P), photos (multi-mode), beauty mode, panorama mode (front support), although not as slow as the iPhone, it is very rich in functions, especially the multi scene in "photo" mode.

Here are some brief introductions:

Ultra clear mode There are 2400W and 5000W pixels to choose from. The advantage of ultra clear is that it can retain more details than ordinary photography after being magnified. Of course, the waiting time is longer when shooting.

In professional mode: Give full play to the hands-on ability, which can be adjusted, white balance, exposure, shutter speed, etc., and support RAW format saving, which is convenient for post production.

Colorful mode : This mode is a combination of various filters, which should be familiar to everyone. The filter feedback effect is also good.

Panorama mode:

Double exposure:

The rear functions are very rich.

Front camera: support front light compensation+panoramic shooting

With 1600W pixels in front, the beauty function is essential. With the built-in beauty 4.0, it can adjust the skin's redness/whiteness, as well as the beauty effect from level 1 to level 7 。

Pre fill light effect: (For the dark light, it may be possible to improve the brightness of the photo at night. It is recommended Take off your glasses because they reflect light)

Front view: The front panoramic view of R9 is also a highlight. We have never seen the front panoramic view before. From the photos, we can see that the vision is really much wider and the effect is good.

Real time sample: (Photo mode: default)

day:

The daytime live shot samples are good, with high color saturation and powerful macro shooting.

at night:

I chose outdoor shooting at night. It can be seen from the photos that there are many noise points at night. Of course, if the indoor light is sufficient, the shooting effect is the same as that in the daytime.

Photo experience: Compared with IPHONE6, when the camera is started and the phase focusing speed is equal to each other, it can be seen that the shooting speed of R9 is optimized in place. R9 also supports post flash shooting (when the screen is turned off, it can be achieved by pressing power+volume).

Video recording:

From the 1080P video, we can see that the anti shake performance is good, at least there is no "jelly", and the effect is acceptable.

Photo summary:

The front camera of OPPO R9 has gone without saying. High pixels, together with the United States Map+night fill light, make self portraits strong both in the daytime and at night; In terms of the rear camera, the image quality is good in the daytime and the image is sharp, but the night sample is slightly noisy and the picture purity is average. It's a pity that the rear camera is not equipped with optical anti shake and dual color temperature flash.

[Hardware performance]: low-end spicy chicken, or enough?

______________________________________________________________________

The SoC of R9 uses MTK's P10 MT6755, with eight Cortex-A53 cores built in. The main frequency is up to 2GHz. The GPU is Mali-T860MP2 (700MHz). As shown in the latest "Mobile Phone CPU Ladder Diagram", the performance is slightly higher than that of Qualcomm 801 and lower than that of Qualcomm 808. The performance is relatively ordinary, but power consumption and heat control are its advantages.

Someone said that OPPO sold at a low price and a high price, without conscience?

Maybe someone thinks that this SoC is used on a thousand yuan machine like Meilan note3, which means that the MT6755 is a "low-end spicy chicken". Why is OPPO not on 810820?

The following is the analysis made by the individual after searching the data: All of this perhaps Or for R9 Slim and durable (purely personal)

Mobile phones should be light and thin, with low power consumption and good endurance. With SoC like 810820, OPPO or all manufacturers are not able to achieve a very good balance at present, but the data shows that: P10 is the latest solution developed by MediaTek specifically for lightweight and fashionable terminals. It provides high-performance multimedia performance while continuing the low power consumption route. Therefore, it may not be surprising for manufacturers such as OPPO or Jinli who pursue lightweight mobile phones to choose MT6755.

Having said so much, whether the MT6755 is enough or not, we will come to a conclusion through actual tests.

First, the score test chart is attached: the score of 5W is relatively average, medium level, but this level is really weak?

Actual measurement of single game: 3D large-scale games are the most important test of GPU performance. Select the currently popular single player games with the size of more than 1G for actual measurement.

Thanks to R9 and 64G of memory (the system occupies 7G and the rest 57G), there is no need to worry about the size of the game.

Large game test: wild racing, explosive gathering, NBA2K 16

In the above game performance, it is very smooth, so the game performance of R9 is excellent, which really surprised me.

Note: OPPO's own "Game Center" does not support the installation of some large-scale games (or cannot be installed after downloading). You can install and download large-scale games by downloading third-party application stores. (such as pea pods, 91 assistants, etc.)

Heating condition:

The temperature was measured 30 minutes after the game was running. The maximum temperature before and after the measurement was 37 degrees, below 40 degrees. The feeling of warmth was felt, but it was not hot. It was enough to see that the MT 6755 was well controlled in temperature.

Through the above practical tests, it can be found that the MT6755 is very smooth in running games and system software experience with 4G RAM storage, especially in large stand-alone games. Of course, the 4K video decoding ability is average, but fortunately, the mobile terminal is basically 1080P video, and can maintain a low heat, achieving a good balance. For most female friends, this mid-range MT6755 is enough. Don't worry too much.

『 VOOC flash charging+ Endurance 』

______________________________________________________________________

First, let's talk about the endurance: when the R9 is equipped with 2850 mA, the power of this 5.5 inch slim mobile phone is in the upper middle level. After the actual trial experience, it takes 1.5-2 days for light use, and one day for heavy use. When the Wifi is turned on, the power consumption for night standby is 3 points, This is a normal level.

Let's talk about flash charging:

How did "charging for 5 minutes, talking for 2 hours" come about?

1、 VOOC flash charge: According to the measured charging data, when the remaining 6% of the electricity is charged, the electricity will be 13% after 5 minutes, 50% after 20 minutes, 70% after 30 minutes, and 6% - 100% will take 1 hour and 10 minutes in total. The performance of R9 is absolutely fast in the generally more than 2 hours of charging, and the first half of the charging speed is quite powerful. Of course, this is inseparable from the 5V 4A flash charging package and VOOC flash charging technology independently developed by OPPO.

2、 Low voltage mode: Of course, if the power consumption of the mobile phone is large, it can not achieve 2-hour call. The low voltage mode of R9 will be turned on when the power is lower than 20%. At this time, the screen brightness will be turned down and some auxiliary functions will be turned off to achieve the minimum power consumption (similar to the super power saving mode on Samsung S5). This function is very practical. It is measured that 1% of the power will be lost in 4 hours (during which the screen will be turned on several times).

other:

WIFI： Restricted by the chip of MT 6755, R9 supports 802.11 b/g/a/n, but does not support the latest 802.11ac standard. However, 5G and 2.4Gwifi are in good use, with stable connection signals and fast speed.

tone quality: Because the sound quality is subjective and I am not a music burner, I just play it out and use earphones (original earplugs/K420/JVC earplugs). The playback effect is acceptable, but not amazing.

conversation: The call volume is high and the background noise is slightly low.

『 summary 』

______________________________________________________________________

① Ultra narrow edge/breathing light button/full metal back, high face

② , Ultra thin body 、 Excellent handle

③ 0.2 second fingerprint unlocking speed is amazing and the success rate is high

④ 1600W front camera with rich functions and outstanding effects

⑤ The system UI localization function is practical and runs smoothly

⑥ Low heating Long life, fast flash charging

Disadvantages:

1. Speaker position design is unreasonable

2、 There are obvious traces of imitating Apple in terms of UI details, A few software are generally compatible

3. Rear camera configuration/performance is average (especially at night)

4. Prices are slightly higher

After my detailed use experience, I believe that you also have some understanding and judgment of OPPO R9. In addition to the super strong selfie and flash charging featured by R9, the experience improvement brought by super narrow edge+super fast unlocking cannot be ignored. The body details of R9 are well handled, and the 5.5 inch mobile phone has a 5-inch grip. The appearance can be described as exquisite; In terms of performance, the measured SoC of MT6755 does not impose great restrictions on video game experience, but its low heat surprised me; The system UI Color OS 3.0 has been greatly reduced compared with the previous generation, use Stable and smooth experience has also been greatly improved, but software incompatibility and other bugs still exist, and there are indeed traces of imitating Apple IOS; The front camera is powerful, and the rear camera has average performance. 2799 is really not cheap. Women friends may have been happy to judge whether it is worth it or not.
