Vivo iQOO VS Xiaomi Mi9 VS Lenovo Z5 Pro GT Review: Which One is Better


The era of Snapdragon 855 finally arrived. Before the Lenovo Z5 Pro GT grabbed the SnapDragon 855, Xiaomi Mi9 declared that it was the real starter of Snapdragon 855, and immediately after Xiaomi Mi9, vivo also released a new brand Vivo iQOO. The same uses the Snapdragon 855 processor. All three mobile phones use the 855 processor, which is also the main price/performance ratio, all at around 3K.

Today, we will come to PK, look at the Lenovo Z5 Pro GT, Xiaomi Mi9, iQOO three mobile phones, who is the king of the price of the Snapdragon 855. Appearance: radish greens have their own love, but the proportion of Lenovo screen is really high. On the screen side, all three mobile phones use AMOLED screens, and there are also optical screen fingerprints, but Z5 Pro GT and Xiaomi Mi9 are fingerprints of the fifth generation optical screen, and iQOO is the fingerprint of the sixth generation optical screen.


In terms of screen appearance, because Lenovo uses a slider design, the screen ratio is higher than iQOO and Xiaomi Mi9. Xiaomi Mi9 and iQOO adopt the current common water drop screen design. If you only look from the front, the screen shapes of the two are exactly the same, you can’t even tell who is who. If I don’t say it, you may only know that Lenovo is at the bottom, and Lenovo with slide design is obviously better in terms of screen ratio. Of course, this comes at a price, Lenovo is also thicker in the thickness of the phone.

From the screen material point of view, Lenovo Z5 Pro GT uses Samsung Super AMOLED screen, the size is 6.39 inches. Xiaomi Mi9 uses Samsung’s AMOLED screen, which is 6.39 inches in size, but the water droplets on the top of the screen account for only about 90.7%. The iQOO’s screen is similar in shape to the xiaomi, with a size of 6.41 inches, which is also an AMOLED screen. At the bottom of the chin width, the three phones are at the same level.

On the border, these three mobile phones have some differences. Xiaomi Mi9 uses a round metal frame, which is more comfortable to hold, while iQOO uses a metal waistline design. The shape of the frame is specially optimized for game grip, which is convenient for the horizontal screen. Time horizontal handshake. Lenovo and the previous two are completely different. Due to the slide screen design, the side of the Lenovo Z5 Pro GT has a double-layer structure and the thickness is thicker. Xiaomi uses a conventional curved border design, iQOO uses a trimmed metal waistline design, brushed blue waistline looks full of personality. From the bottom interface, Lenovo and iQOO use a single-sided opening design, and Xiaomi uses a symmetrical opening design. The three mobile phones are all USB Type C interfaces, but due to design reasons, iQOO’s USB socket has two screws on both sides.

From the top design point of view, the three phones only have the 3.5mm headphone jack reserved by iQOO. The infrared emitter is unique to Xiaomi. Why does Xiaomi have a soft spot for infrared emitters? Of course, it is to be in line with the Xiaomi IOT smart home layout. At the top of Lenovo is the SIM card slot, which may be related to the internal structure of the slider. If the appearance of the three mobile phones is the most different, it is still necessary to look at the back of the three mobile phones, in addition to Lenovo’s lens center axis layout, the other two phones have adopted the upper left corner vertical design. The back of the three phones is made of glass, Lenovo uses carbon fiber texture, iQOO uses track texture, and millet has no texture. As for who is better, it is completely the difference between personal aesthetics.

In addition to these, iQOO has some more personalized designs, the vertical line in the center of the phone is a hidden light strip. There are different lighting effects in games, charging, and incoming calls, which is very cool. Finally, let’s take a look at the buttons on the left side of the three phones. Lenovo puts the volume button on the left side, and iQOO puts an AI button on the left side, as does the millet.


After finishing the appearance, as the three Snapdragon 855 mobile phones of the same price, their performance is the focus of our attention. Let’s start with the running points of the three mobile phones. Sure enough, GeekBench’s three mobile phones are basically the same, whether it is single-core or multi-core, the difference is basically small, basically can be counted within the error, are the normal level of 855. So we still have to look at the tuning of the 855 GPU scheduling for the three phones.

From the results of the 3DMark graphics running points, iQOO has a clear lead, and the rest of the Xiaomi Mi9 is not much different from the Lenovo Z5 Pro GT, both of which are around 67,000. Why is the same Snapdragon 855, iQOO’s 3DMark score is about 7% higher than the other two, currently can only be explained by the 855 tuning optimization, although the use of the Snapdragon 855 model, but the mobile phone manufacturers to the system Optimization coordinated with SOC is equally important? Excellent system scheduling mechanism and underlying optimization can bring a better experience to users. This is obviously more experience as an international mobile phone manufacturer. However, these problems can be solved through post-system optimization, which is not a disadvantage.

If we look at the running points of Ann Bunny, the situation is different. Xiaomi has topped the list with more than 370,000 points over iQOO and Lenovo Z5 Pro GT. From the perspective of the three running points software, the three Snapdragon 855 mobile phones run almost the same, and there is no single-direction sling. Regardless of the running score, there are no problems with the three mobile games. After all, the 845 can now handle most of the games on the market, and the GPU will upgrade the 855 with 20% performance.

We originally wanted to use GameBench to test the frame rate of three mobile games. However, since Xiaomi Mi9 is currently unable to use GameBench to detect the frame rate, we will temporarily postpone the frame rate comparison of the three mobile phones. After Xiaomi Mi9 supports GameBench, it will be tested separately. In terms of the performance of the Snapdragon 855, there is not much problem with the full frame of the game. The problem is how long the full frame of the game can last. Whether the SOC can fully play its strength, but also depends on the ability of the mobile phone to dissipate heat. So we tested the temperature of the phone after the 30-minute stimulus on the three phones. The results are as follows.

It can be seen that iQOO with liquid cooling is the lowest temperature among them. The maximum temperature is only 38 degrees, the temperature control is very good, and the Xiaomi temperature is about 43 degrees, which is not high. Lenovo’s cooling mechanism is relatively weak due to the sliding mechanism, but it is enough to ensure that the game is smooth.


In terms of taking pictures, the three mobile phone camera configurations are different. I simply sorted it out. The chart is as follows:

From the hardware point of view, the configuration of Xiaomi Mi9 is undoubtedly the most luxurious, using the latest IMX586 package, with three focal lengths, the shooting scene is more abundant. iQOO uses the flagship IMX363CMOS widely used in the industry, and daily use is enough. Lenovo uses the 24MP IMX576, and the camera effect is not bad. From the hardware point of view, Xiaomi has won. Of course, the hardware is on the one hand, the algorithm is equally important for the optimization of the camera, so we still look at the proofs.

Xiaomi Mi9/iQOO/Lenovo Z5Pro three 855PK Who is the king of the cost? Xiaomi Mi9/iQOO/Lenovo Z5Pro three 855PK Who is the king of the cost?Millet 9/iQOO/Lenovo Z5Pro three 855PK Who is the king of the cost? It can be seen that the iQOO mobile phone is better in color and vividness than the other two mobile phones, while the 48 Megapixel blessed xiaomi is more delicate in detail, and the color of Lenovo is more realistic, no Too many traces of AI enhancements look more natural.

Of course, the photos still look subjective. There is no absolute difference between good and bad. Whoever prefers the sample, you may forget the model, take off your prejudice against the model, and take a closer look. On the self-timer, the three models are brighter with iQOO, the color is more saturated, although the brightness of the millet is slightly lower, the beauty algorithm is still good, Lenovo is slightly darker in the background, of course, retains more skin details. As for which is the most beautiful, you still have to look at it yourself.


In terms of battery life, Xiaomi Mi9 uses a 3300mAh battery, iQOO uses a 4000mAh battery, and Lenovo Z5 Pro GT uses a 3350mAh battery. In terms of battery capacity, iQOO is significantly ahead of the other two phones. In the fast charge, iQOO is also significantly ahead of the other two mobile phones, iQOO’s unique 44W fast charge makes it the leader in charging speed. How fast is it, everyone can understand the picture below.

It can be seen that the iQOO charging speed of the 11V-4A charger with a power of 44W is significantly ahead of Xiaomi and Lenovo. It should be noted that the battery capacity of iQOO is also much higher than that of 3300mAh, reaching 4000mAh. Using the QC4.0 charging protocol, the Xiaomi Mi9 with a power of 27W is followed by a charge of 58% for half an hour. At the end of the list is the Lenovo Z5 Pro GT using QC3.0, it seems that Lenovo has to follow up the QC4.0 agreement. Of course, in addition to the wired fast charge, Xiaomi 9 also has a 20W wireless fast charge, which is not available in the other two mobile phones. Since there is no reference object, we will not compare it.

On the system, all three mobile phones use the Android 9-based system, but the interaction methods of the three are different. Let’s start with system navigation. In fact, the development of Android to today, the major manufacturers are basically in place in the function, can reflect the difference is often the system details and interaction design.

Return to the upper level on the bottom, the upper stroke stops back to the table, and the bottom side slides inward to enter multitasking. This interaction is actually quite smooth, of course, people who have never used it should be familiar with it for a while. In addition to Lenovo, the other two are focused on their own intelligent voice assistants, let’s take a look at their comparison. The two voice assistants have different focuses. Xiao Ai is more equipped on different IoT terminals to build a complete set of the intelligent ecosystem, while Jovi focuses more on intelligent instructions and uses simple preset learning to facilitate life. If you look closely, you will find that the internal pages of Xiao Ai’s classmates are mostly based on the simple instructions of “listening”, which is beneficial to the interaction of Xiaomi’s IoT devices. Jovi’s combined instructions can be freely added to form an automated and convenient operation.

It can be said that they can help you solve the problems in life, but little love is more related to the smart home, Jovi is more focused on the phone itself. Of course, iQOO and Xiaomi also have their own game space. Although the game box on iQOO has appeared on previous generations of vivo phones, the Game Turbo on Xiaomi is still the first time. Let’s take a look at their comparison. Xiaomi Mi9’s Game Turbo game mode can enhance game touch and has game display effects, customized sound parameters, and other functions. iQOO is upgraded to vivo Multi-Turbo based on vivo Dual-Turbo, integrating multi-dimensional optimization of network, cooling, AI, games and the underlying central core resources. It also brings game box function to gamers, which can be more focused. Game experience.

In general, if you are a game fanatic, choosing iQOO is always right, no matter what kind of game experience, iQOO is a game phone. Of course, if you are more interested in Xiaomi system and Xiaoai classmates, or if you have a full set of millet appliances in your home, choosing Xiaomi is the right choice. If you are interested in slider interaction, Lenovo may wish to try.

Although these three products use the Snapdragon 855 processor, which is also the same price (mainly cost-effective), these three mobile phones have their own weight, have their own unique selling points. The selling point of Xiaomi Mi9 is photography, performance and monkey play; Vivo iQOO‘s selling point is gameplay, performance, and fast charge; Lenovo Z5 Pro GT‘s selling point is the high screen ratio brought by the slider and the first launch Snapdragon 855.

You can look at which selling points are more interested and choose according to the selling point. If you like to take pictures and fashion, Xiaomi Mi9 is worth choosing (premise you can grab); if you like to play games, personality appearance, powerful battery life, then iQOO is your best choice; if you have a respect for screen occupation Lenovo can also consider it.

Of course, judging from the current sales situation, these three products are basically products that need to be reserved in the official channels. Who can get more users to favor, in a sense, it depends on the big manufacturers. The screw is screwed fast. Finally, I still want to say: Anyone who plays the price/performance ratio will do the best.
