Hi, I'm Xiao Su. I used to dive. I watched the offer silently. I recently registered. The first time I wrote the original comparison, I wanted to change my mobile phone to a new one. Please also include a few:
Has always insisted on using iphone 4s, frustration screen is too small, it is a bit tired, finally decided to change the screen but does not want to be too large, and hopes to be simple and easy to use mobile phones. In the subway station that commutes to and from work every day, a series of large advertisements of oppo R9 “charge for 5 minutes, call for 2 hoursâ€, brainwashed successfully, went to Suning's shopping mall, tried many mobile phones, and finally chose OPPO R9 (also the life of the factory girl), personal feel more appropriate size, shape feel beautiful, with a pretty handy, beauty self-timer, so buy it.
Suning Tesco's link is as follows, a price:
One. AppearanceThe second time was fake out of the box, because it was already opened during the purchase in the store.
The white box, in addition to mobile phones, chargers also presented a headset, plastic transparent phone shell, as well as a transparent film has been posted.
Positive: The large 5.5-inch screen occupies a large area with a very narrow border. The screen shows good results.
With a big screen, I feel more cool, and since then the small-screen mobile phone will be slightly lower! (Original iphone4s and oppo r9)
The reverse side: all-metal body, but the two signal lines are too obvious slightly, as well as the camera highlights (bad review bad review ~ ~)
Above: There is a self-portrait camera, and Mei Mei's self-timer depends on her! There is a light sensor and earpiece
The following: The home key of a physical entity like a playground track, with fingerprint recognition, feels good. Turning from the iphone feels good is the use of the home button on both sides of the virtual button, the left is the menu button, the right is the return button, do not need to iphone like every time you want to move to the top left corner of the screen press return, more convenient. In addition, the virtual key is lighted. 
Take a look at the waist line, haha, not the A4 waist, is the God horse "consolidate the waist line," and feels easy to get started.
On the left is the volume key
On the right is the card slot and power button, buy the full Netcom, supports dual card dual standby 
There is no interface at the top and the interface is at the bottom. Headphone jack, charging USB port, and speaker jack
Summary: In terms of appearance, the large 5.5-inch screen does not feel particularly large, the back of the metal body feel more delicate and smooth, the front screen covering the 2.5D arc glass, the phone is more comfortable to grasp, the positive appearance of the comparison It looks good, but the two signal lines behind it look a little abrupt, and the rear camera highlights badly.
II . Charging and battery life
The advertisement was bombed by "charging for 5 minutes and calling for two hours." Well, but who can insist on talking for 2 hours, but the actual charging speed is still relatively fast. Observed that every 10 minutes can be charged 20%, so that if there is no electricity for a temporary flush, it should be able to persist for some time. 40 minutes can be charged 80%, slower behind, full of electricity with about 70 minutes, may be on the one hand the battery capacity is not very large, only 2850 mA, the other is the oppo uses 5V/4A fast charging technology.
But found a problem, originally thought that his charging line interface is micro usb, and usually see the same shape is a later found that the head is not the same found in the oppo connector is 7 pin, the standard should Just 5 needles. This design is drunk, why not use the standard? To use the charging line is troublesome.
In terms of battery life, I use the blue whale to say "No. Because the battery is not big, the intuitive feeling is not durable. It is basically a day full charge. A blink of an eye to sleep, 3% of the electricity gone; watching the video for 1 hour, about 13% of the electricity; game for 1 hour, about 26% -30% of the electricity is gone; listening to the song for 1 hour is OK, about 6% Electricity.
Summary: life is a weakness, but fortunately faster charging can make up for a little, but the charging line connector is not a common line of borrowing is too much trouble.
III. System and Function
The Android system for mobile phones, each mobile phone manufacturers to do the system I feel is to do the conversion, this change is called the colos OS, that house was changed called MIUI, and so on, the oppo home is the color OS. The original use of iphone, for Android phone feeling after using it is quite convenient, (although it is always heard that the chance of using Android more cards, do not know how to break?). The icon of the system is somewhat similar to the iphone, and it is quite nice to see; the arrangement of the icons is also like that of the iphone, which is automatically sorted by the left and cannot be customized.
The system setup is simple at a glance, and it is also used by my novice. There is a file management, and qq and WeChat are specifically listed separately. It is convenient to find files.
The drop-down menu is divided into two pages, sliding and switching, one page is the notification, and one page is the shortcut key. Feeling is still better on a page, lazy, do not want to change.
Comes with a "theme store", there are many free themes can be replaced; "software store" can download all kinds of applications, without the need to download certain assistants; "mobile phone butler" can clean up the accelerated mobile phone;
Finding the fun is the lock screen wallpaper, each time the screen is lit is not the same wallpaper, the United States and the United States to learn to do a tif move
Fingerprint recognition function
The frontal home button integrates the function of fingerprint recognition. This function is really easy to use. As fast as the official propaganda, it responds quickly. When the finger is pressed, it is opened. The blue whale is a cool YBDZ.
Fingerprint recognition capable horse? Can unlock the boot, you can also use Alipay payment, you can lock the application, you can also file insurance, and you can... Nothing. Support for adding multiple fingerprints, so you don't have to use one finger, haha. However, it has also been found that different fingerprints cannot be set to different roles.
Summary: The system is relatively smooth to use, set up more convenient, easy to use after learning to use, the system interface is more unified and beautiful, fingerprint recognition is very easy to use! However, it is not possible to customize the placement of the desktop icons, fingerprints can not be set to different functions.
Four. Photographs
The front camera of this mobile phone is high in pixels and is equipped with beauty software. Therefore, it is a big gospel for a girl who likes to take a self-portrait. The test shot came out of the United States and he could not recognize himself. It scared everyone and didn't have a reality show. ~
The camera feels good to use, the focusing response is quick, and it's easy to use it. Here are some pictures taken by the way to IKEA:
Other soap tablets
If you take pictures at night, the focusing speed is fast, but the photo effect is not as good as the daytime. The noise is still there, and then you can't shake it, otherwise you'll get stuck. It's almost enough to share a picture or a circle of friends. 
This puppy took several shots to have such a good one
The following is a simple comparison with iphone4s. I know this comparison doesn't make much sense. After all, the product is separated by several years (for comparison, hahaha). Above the iphone is the oppo. During the day, the iphone4s looks like a sword. The night photo 4s is a lot worse.
Summary: The camera has a fast focusing speed, good imaging effect of good light during the day, relatively weak light at night, and good cosmetic effect.
Five. Entertainment with Master Lu
If you don't agree, you can run away. Haha, entertain yourself with Master Lu and see if the evaluation results are overkill and unconspicuous. The result is as follows:
Performance evaluation results
Experience evaluation results
HTML5 evaluation results
Six. Use summary
First of all, the advantages: the individual still prefers the appearance of the front, the physical buttons below are easier to use, the fingerprint recognition is faster, and the size of the mobile phone is just right and comfortable. Photographing focus response fast, the effect is also good. Charge faster. To say the shortcomings: the back of the two signal lines do not look good, the camera is prominent; battery life is relatively weak; evening photography is not very good, the system desktop icon can not freely swing position.
