vivo iQOO VS. Xiaomi Mi 9: pretty looks
Prior to the release of Xiaomi 9, Lei Jun said that the phone is "good looking" and also a"fighting angel" on Weibo, and said that this would be the best looking mobile phone. We can not believe all that Lei Jun said, we can know that the phone is really good-looking. In terms of screen, Xiaomi 9 carries a 6.39-inch Samsung AMOLED water drop screen with a resolution of 2340x1080. The mobile phone's rim is very narrow, and the screen accounts for 90.7%. The screen looks very simple as a whole. After one year's precipitation, the water drop screen is not much to blame in daily use.
The back of Xiaomi 9 is made of full-curved glass technology. There is not a straight face in the whole back. The arc design is used in the places seen by naked eyes and touched by palms. From the side, the smartphone body of this arc design will be very thin, so the grip experience is very good. As for color matching, Xiaomi 9 routinely provides three kinds of color matching, black, phantom blue and phantom purple, all of which are designed with nano holographic texture. In other words, the illumination of phantom blue and purple can reflect different colors under different lights, which seems to capture the feeling of a rainbow in the body.
Overall, the Xiaomi 9's body is a little different from the Aurora Gradient, which was popular in 2018. However, if Aurora gradient is the "non-mainstream Renaissance" of the new era, then Xiaomi's magic color is the "Renaissance" with more refinement and higher grade. Here I recommend magic purple. It has a fantastic pink vision in the light. It's atmospheric enough for both men and women.
In addition to the fantasy color matching and full-arc fuselage, its delicate features "circle" a rainbow texture on the 1200 portrait lens in the rear three-shot, so that Xiaomi 9 was nicknamed "disco 9" by many netizens.
As for vivo's new brand iQOO, which is also a powerful and beautiful mobile phone, iQOO carries a 6.39-inch Samsung AMOLED water drop screen on the screen, with a screen ratio of 19.5:9 as Xiaomi 9. The screen is large but the whole phone looks very slender. IQOO also uses very narrow border design around it. The narrowest border is only 1.76mm, and the screen proportion is 91.7% higher than that of Xiaomi 9.
In fact, whether it is water drop screen or other non-side screen, after continuous upgrading and improvement in 2018, it has a very good screen proportion and look. So if you want to distinguish the appearance of iQOO and Xiaomi 9, you can only compare the color of the back of the mobile phone. The previous article mentioned that Xiaomi 9 was jokingly called "disco 9", while iQOO was jokingly called "horse-running light" by netizens. This is mainly because there is a main black color matching high-matching version of iQOO in the two versions of iQOO, whose back can turn on the game light effect.
The ordinary version of iQOO can be said to be very novel in the design of the backplane. When I tried it, I found that its design style can be expressed in one word - streamline. In the gloss, iQOO has classic lines like the corners of a sports car. In fact, the back of iQOO mobile phone is made of 3-D curved glass. After complex AG coating process, the body looks very textured and has a good light reflection effect. It has glass texture on the handle. With the design of four-sided arc of the body, the grip experience is the same as that of Xiaomi 9, but it is slightly better than Xiaomi 9 in the degree of fingerprint contamination.
In addition, iQOO is mainly about game experience, so manufacturers have also made some optimization for game experience in the mobile phone design. In the middle frame of the right side of the mobile phone body, there are red color bumping switch keys, volume addition and subtraction keys and Monster Touch pressure keys, which can realize the four-finger control of the game, somewhat similar to the "Playerunknown's Battlegrounds’s assistant" . In addition, iQOO also retains a 3 mm headphone jack, which will undoubtedly be a good thing for many headphone controllers.
vivo iQOO VS. Xiaomi Mi 9: CPU performance and battery comparison
Xiaomi 9 and IQOO mobile phones are equipped with the strongest microprocessor of Android at present. The microprocessor is manufactured in 7 nanometer process. The highest main frequency can reach 2.84 GHz. Compared with the microprocessor, 855 has a great improvement in overall performance. So the two mobile phones are excellent in operation and application fluency. However, there is a big difference between the two in terms of endurance, game experience and photographic performance.
First of all, in the game experience, Xiaomi 9 carries 3200 mAh batteries and supports the Game Turbo game technology. For those who like to play Playerunknown's Battlegrounds, Xiaomi 9 is enough for them. Because the game experience under snapdragon 855 can be basically run in full frame, there will be no drop-off or carton embarrassment.
After the actual measurement, the ability of Xiaomi 9 in the game is not very strong. The game of 50% brightness and 80% volume in an hour consumes 84% of the cell phone's power from 100%. There is no overheating in the cell phone, but the hand can still feel the heat higher than the body temperature.
In terms of charging durability, Xiaomi 9 carried a 3300 mAh battery with built-in fast charging of 27W, and supported 20W wireless fast charging. In other words, both wire charging and wireless charging can be filled in about an hour and a half, that is, wired charging in the "left" and wireless charging in the "right".
As for iQOO, it is a snapdragon 855 mobile phone. It has many obvious advantages in the game. First of all, iQOO carries a 4000 mA battery. At present, the mainstream flagship phone carrying 4000 + mA battery is rare. As a main game mobile phone, iQOO is obviously better.
IQOO also adds game elements to the design language of the body. There are two additional press virtual keys at the metal border of the phone. You can press the unique game space of the mobile phone, or you can use the virtual press button to complete the functions of "opening mirror" and "shooting" in the game, and complete the four-finger operation, similar to "Playerunknown's Battlegrounds weapon", but also a little four-finger operation in the two-sided screen mobile phone.
In addition, iQOO’s standard charging line has also been processed differently. It is connected horizontally. Officials say it's easy to play games while charging. Although many people say it's useless and they are used to "inserting" the charger interface into the fingertips, they need to press the virtual keys in the actual experience. The comfort of the "pill" connector is obviously very high.
In terms of charging endurance, iQOO adopts fast charging technology with 44W peak. Generally, the wattage marked by fast charging is the charging wattage in the peak state, which does not mean that from the beginning of charging to the end of charging, it can be charged stably at the identified wattage level. According to the data, the 44w peak of iQOO lasts for 15 minutes, that is to say, when the cell phone is powerless, the peak charge of 15 minutes can make your cell phone last for another day. After actual measurement, it takes 16 minutes for iQOO to charge 50% from 0%, and a total of 44 minutes to reach 100%.
In addition, Xiaomi 9 adopts the fifth generation under-screen fingerprint unlocking technology. It is known that this is an optical fingerprint sensor composed of three lenses hidden under the OLED screen. It is similar to a micro-distance camera, with a single pixel of up to 5 micrometers. The fingerprint recognition speed is fast and has a very high accuracy. At the beginning of the release of Xiaomi 9, the fifth generation under-screen fingerprint technology was touted as the "fastest way to unlock". However, in the sixth generation of fingerprint under screen unlocking technology iQOO appeared, Xiaomi 9 ushered in the first blow. Maybe you can't experience which is faster through a single cell phone, but if Xiaomi 9 and iQOO are unlocked together, the gap will appear.
vivo iQOO VS. Xiaomi Mi 9: camera comparison
Xiaomi 9 scored 107 points for its photographic performance on the DxO evaluation website, ranking third in the current ranking. In terms of camera configuration, Xiaomi 9 uses a 48 million main camera modeled as SONY IMX586. Two of Xiaomi 9's side shots include Samsung's 12 million portrait lenses supporting double optical zoom, and the new 16 million 120-degree ultra-wide-angle lens, which can support 4cm ultra-close-range shooting. In addition, Xiaomi 9's front-end camera is 20 million pixels.
Xiaomi 9's ultra wide-angle power lens can capture a wide range of object scenes. When shooting buildings, it will recommend opening the ultra-wide angle function to help users take a broader panoramic view. The main color of the sample is close to the reality, the edge sharpness is enough to show the true color of the object, and the details of the dark part can also be clearly imaged.
Under the condition that the highlights of the night scene are comparatively clear and the light and shade are comparatively clear, the scene displayed by the sample sheet is still more prominent. However, there are still some blurred phenomena in the dark area around the main body at a high range, and there is no clear picture of the arrangement of the dark branches.
Under sufficient illumination, the performance of the sample is very satisfactory. Whether it is a remote village or a nearby plant, the camera can clearly distinguish, so as to achieve the unity of long-range and near-range display.
In the ultra-close shooting mode, the background visualization function of the sample is relatively strong, and the foreground part outside the main scope also achieves the visualization processing.
As for the pre-selfie of Xiaomi 9, the camera can accurately identify the main body of the person. It has a relatively good "matting" ability, the overall self-portrait image effect is still very good.
In iQOO's photo configuration, it is equipped with three rear cameras, with a Sony IMX363 sensor. Its three cameras are 12 megapixels + 13 megapixels + 2 megapixels. It carries a 12 megapixel front-end camera. Officials say iQOO phones also support Super Night View, which allows you to take detailed and noisy photos in a handheld state.
In the outdoor image sample, iQOO's picture is full of color, while the details are restored in place. The sample picture appears very clean, and still maintains a good imaging ability in the case of insufficient sunshine in overcast days.
In the wide-angle imaging part, the 13 million-pixel ultra-wide-angle lens supports 125 degrees ultra-wide-angle photography, which can not only retain the main content of the picture, but also record the surrounding environment in the lens.
In iQOO's handheld super night scene mode, the image effect is good, it can clearly restore the details of the dark and highlight parts, and the picture does not have too much noise.
In terms of the lens, iQOO has a dual-core 12 million-pixel camera, f/2.0 aperture. It supports backlighting mode and AI beauty. In the default self-timer mode, the details and colors of the picture are fairly good. Its beauty effect is more natural. Its cosmetic effect has been significantly improved, and the details have been well preserved.
Whether from the specific parameters or from the first experience, the advantages of IQOO lie mainly in the battery performance and charging. The overall configuration and even language design are more inclined to the game mobile phone. Xiaomi 9 has a better photography and touching feel, as well as a very good-famed Xiaomi MIUI system. It can be seen as a high cost-effective bucket flagship smartphone. Of course, the Xiaomi 9’s 3300mAh battery may not be as good as iQOO, but coupled with the new generation Snapdragon 855, it will performs better than the Xiaomi Mi Mix series smartphones.
