In the 1.5K range of smartphones, ultra-100W fast charging is equipped with a 5000mAh dual-cell battery. The fuselage becomes thicker and heavier, so many mobile phone manufacturers reduce the equivalent capacity of the battery to realize the application of dual-core fast charging. What beast this situation was the just-released iQOO Z7, which brought a dual-cell high-capacity battery equivalent to 5000mAh and 120W ultra-fast flash charging into the 1.5K gear for the first time, thus creating the “battery life superman.”
The iQOO Z series has always been adhering to the concept of high-cost performance. The iQOO Z5 launched last year, with the Snapdragon 778G chip + LPDDR5 3200MHz full-blooded memory and UFS 3.1 full-blooded flash memory, has opened up the performance iron in mid-range models—Triangle combination.
This year’s iQOO Z7 continues to carry forward this concept. The series launched Qualcomm’s 6nm mid-range chip Snapdragon 782G, so iQOO Z7 has another title-“Performance Superman.”
Combining these two titles, iQOO Z7 is known as the “Little Superman of Performance and Battery Life.”
1. 5000mAh full blood battery + 120W dual-core flash charge 1.5K file first
In the 1.5K gear, many mobile phones are equipped with 5000mAh batteries, but few can be fitted with 120W high-power fast charging.
As a model of the same price, iQOO Z7 is the first to put this almost incompatible fast charging combination into the mobile phone.
At the same time, a dual-cell battery is used, and the charging power is faster under the same control, thus becoming the first mobile phone to use a 5000mAh battery + 120W dual-core fast charging in the 1.5K price segment.
2. Snapdragon 782G low power consumption 6nm core daily + no pressure for games
The Snapdragon 782G chip has a 1+3+4 three-cluster architecture design, one 2.7GHz A78 performance core, better experience in high-load scenarios; three 2.4GHz A78 performance cores to meet the needs of large mainstream applications; four 1.8GHz A55 The nature of energy efficiency, easy to control for daily applications.
The eight-core chip has a clear division of labor and balances performance and power consumption. It is also known as a high-energy and practical chip that is budget-conscious.
3. The Z series is first equipped with infrared remote control, and the mobile phone becomes a remote control in seconds
iQOO Z7 also uses an infrared remote control sensor for the first time in the series, which can replace various electrical remote controls at home. It supports nearly 1,600 brands of household electrical equipment, such as TVs, projectors, air conditioners, and fans, and avoids piles of remote controls. When looking for a difficult situation, a mobile phone can easily power infrared appliances.
Design & Screen
The front of the iQOO Z7 uses a 6.64-inch LCD screen with a resolution of 2388×1080, supports a refresh rate of up to 120Hz, seven-speed automatic adjustment, and a static contrast ratio of 1500:1 that is consistent with most LCD screen phones.
The iQOO Z7 uses a centered front camera with 16 megapixels, which has a good resolution when taking selfies. The chin’s width is also considered at the same price level.
The color of the product we got is Infinity Orange, the surface adopts nano-lithography technology, and the back panel of the fuselage is separated by 11 ridges; shining under the light, you can see the details of each stripe, and the touch is silky—any sense of isolation.
Vientiane cloud-level design has always been the tradition of IQOO mobile phones. This refined and slender color-contrasting cloud-level design interprets the beauty of rational exploration.
Of the two camera modules above, the primary camera supports OIS optical anti-shake, and the right side is a single LED fill light.
There is a 3.5mm headphone jack on the top of the fuselage, the infrared remote control sensor is on the right side, and the noise reduction microphone is on the left side. The bottom of the fuselage has a speaker opening, a Type-C interface, and a primary microphone, and the right side is the SIM card slot.
The volume button and power button of the mobile phone are located on the right side of the fuselage, and the power button integrates a fingerprint recognition module. The accessories include a fast charging kit, a silicone phone case, an instruction manual, and a SIM card pin. The fast charging adapter supports a short charging power of up to 120W.
iQOO Z7 is equipped with a Qualcomm 6nm mid-range chip, Snapdragon 782G, one 2.7GHz A78 performance core, better experience in high-load scenarios, three 2.4GHz A78 performance cores to meet the needs of large mainstream applications, four 1.8GHz A55 energy efficiency The body is easy to control for daily applications, and it is supplemented by up to 12GB LPDDR4X+256GB UFS2.2 storage.
Next, we conduct a set of theoretical benchmark tests.
The first is AnTuTu’s comprehensive performance test, with a total score of nearly 600,000 points, including 170,000+ for CPU and 180,000+ for GPU.
In the CPU single test, the GeekBench5 single-core score is 869 points, and the multi-core score is 2840 points, regarded as the mid-range level.
The latest GeekBench6 ran a single-core score of 1120 and a multi-core score of 3018.
Next is the GPU test. In GFXBench, we selected six 1080P routine tests, among which the frame rates of the first three items of Aztec ruins OpenGL, Aztec ruins Vulkan, and racing chase reached 40FPS, 45FPS, and 37FPS respectively.
In the last three tests, the frame rate will also drop slightly due to the gradual increase of the mobile phone temperature. Manhattan 3.1, Manhattan, and Tyrannosaurus rex ran 65FPS, 87FPS, and 151FPS, respectively.
In general, the GPU performance of the Snapdragon 782G is comparable to that of the Snapdragon 778G Plus.
In the Androbench test, the sequential reading speed reached 1009.27MB/s, the sequential writing speed went 833.85MB/s, and the random reading speed was 251.11MB/s the random writing speed was 260.31MB/s, which met the UFS 2.2 level.
In the memory test, the memory specifications of LPDDR4X, the copy speed reached 67.9.8MB/s, and the write speed reached 14314.9MB/s.
In the game testing session, we selected three mobile games that can represent medium and high loads and reflect the actual performance of mobile phones under low, medium, and high loads in an office environment with an indoor temperature of 24 degrees Celsius. Peace Elite and Call of Duty are tested.
During the test, we adjusted the brightness of the mobile phone screen to 50% and turned off the automatic brightness to ensure the accuracy of the test. We used the highest image quality + highest frame rate for testing in the game and recorded the frame rate, the performance of temperature, and power consumption.
1. Glory of Kings
The first is the test of the Honor of Kings mobile game. With high-definition picture quality and extremely high frame rate, after a team battle for nearly 15 minutes, the average frame rate reached 119.8FPS, and the frame rate fluctuation was only 0.9FPS. The Snapdragon 782G can run smoothly in the face of such low-load games without any changes.
In terms of power consumption, the average power consumption is about 3.6W, and the frame energy consumption is 30mW. The energy consumption is not high and is at a medium level in mid-range mobile phones.
The highest temperature on the front of the fuselage is 40.2 degrees Celsius, and the highest temperature on the back is 39.7 degrees Celsius. While playing games, you will feel some warmth from the rear of the fuselage.
2. Peace Elite
In the Peace Elite mobile game, the smooth picture quality can be turned on at the limited frame rate, and the game runs at a maximum of 60FPS. After nearly 16 minutes of testing, the average frame rate remained at 59.8FPS, and the overall frame rate curve remained the same, Very smooth.
In terms of power consumption, since the game runs at a maximum of 60 frames, the average power consumption is lower than that of Honor of Kings, only 2.8W, and the frame power consumption is 46.8mW.
The highest temperature on the front of the fuselage is 37.7 degrees Celsius, and the highest on the back is 37.5 degrees Celsius. You can hardly feel the heat when holding the phone with both hands.
3. Call of Duty
In the Call of Duty mobile game test, under the high-definition picture quality + extreme frame rate, the frame rate will drop due to outsiders, so we only record the frame rate curve during the battle, and there is no significant drop in the game for nearly two and a half minutes Frame, the average frame rate is stable at 59.4FPS.
In terms of power consumption, the average power consumption of 2.93W is also excellent, and the frame energy consumption is 50.4mW.
With such a low power consumption, the temperature will naturally not be high. After three rounds of games for nearly 8 minutes, the front of the fuselage is only 36.8 degrees Celsius, and the back is only 37.3 degrees Celsius.
The iQOO Z7 has two rear cameras; the primary camera is the 64-megapixel Samsung S5KGW3 CMOS, 1/1.97-inch photosensitive unit, 0.7µm single-pixel size, and f/1.79 aperture. The biggest highlight is that it supports OIS optics Anti-shake; it has excellent stability and a higher output rate for long-exposure scenes at night.
Another depth-of-field lens is 2 megapixels, with an f/2.4 aperture, 24mm equivalent focal length, and a 1/5-inch photosensitive unit, mainly used for blurring portraits.
In the daytime scene, the samples of iQOO Z7 have relatively high saturation. This kind of optimization looks more pleasing to the eye at first glance, and in the backlit scene, the picture taken with two times cropping will not be blurred, although the dark part will be confused. It’s a little dark, but the look of the light amount is still relatively transparent. In nighttime scenes, the use of long exposure can further reduce the noise of the picture, and it also has a relatively good effect on the suppression of highlights. The details of the proofs are also evident when zoomed in, which is enough to see that Z7 is still very good at optimizing the camera. Of.
iQOO Z7 has a built-in dual-cell equivalent 5000mAh high-capacity battery and supports 120W ultra-fast flash charging. The battery and charging specifications have surpassed most flagship phones, so this is also the advantage of the iQOO Z7.
To ensure the safety of fast charging, iQOO has introduced an intelligent charging strategy and an anti-aging charging algorithm.
When the mobile phone detects that it is playing games or live broadcasting for a long time or when it is empty, it will intelligently adjust the charging power to prevent excessive heat from shortening the battery life.
When the mobile phone is used for a long time, the system will intelligently reduce the full charging voltage and maximum charging current according to the aging degree of the battery, thereby reducing the loss of the storm and prolonging the service life of the storm.
In this regard, we also tested the charging ability and battery life of the iQOO Z7.
First, we drain the phone’s power to 5%, conduct a charging test with the screen off, and record the power every 5 minutes.
After 5 minutes, the power reaches 26%, 10 minutes to 49%, 15 minutes to 68%, 20 minutes to 85%, and finally fully charged in 26 minutes.
We usually charge for such a high-speed charging capability, brush our teeth and wash our face, and the delegated power is enough for most of the day.
For the battery life, we use a professional battery life test tool – the battery dog produced by Kuai Technology.
In terms of test items, we chose the extreme power battery life test and checked all the test items, including CPU high voltage, CPU multi-threading, AI recognition, picture browsing, video playback, and web browsing, to simulate user usage scenarios and restore the whole load to the greatest extent. Infinitely close to the actual power consumption.
We adjusted the refresh rate of the mobile phone to intelligent switching, changed the brightness of the mobile phone to an exact 50%, and turned off the automatic brightness. After measuring the battery dog, it took 10 hours and 55 minutes to consume the power from 100% to 7%. The total endurance score can reach about 11.7 hours and is a proper endurance king. It seems that the title of “performance endurance superman” is well-deserved.
120W dual-core flash charging, 5000mAh large-capacity battery, and the balanced processor Snapdragon 782G give iQOO Z7 the title “Little Superman in Performance and Battery Life.”
After our experience, the comprehensive capabilities of iQOO Z7 are summarized as follows:
1. Dual-core 120W ultra-fast flash charging with the lowest starting price
The rare 120W dual-core fast charging at the same price and a large battery equivalent to 5000mAh has a faster charging speed under the same power. After testing, it can charge to 40% of the energy in 10 minutes, so you don’t have to rush when you go out temporarily, and The mobile phone can be revived with whole blood within half an hour, and the battery life of nearly 11 hours of continuous use also allows those who are anxious about battery life to get rid of their troubles completely.
With a starting price of only 1599 yuan, it has become the industry’s lowest-priced mid-range mobile phone with dual-core 120W ultra-fast flash charging.
2. The Snapdragon 782G chip balances performance and power consumption
TSMC’s 6nm Snapdragon 782G mobile platform, while having excellent performance, can balance power consumption. There is no pressure in the face of various large-scale mobile games, and daily software use is even easier. It can be said that the iQOO Z7 commission is also one of the best among thousand yuan phones.
3. Optical image stabilization makes it easier to produce night scenes
The iQOO Z7 also continues the previous generation’s OIS optical image stabilization function. The output rate of day and night scenes has been dramatically improved, especially in night scene imaging, which is better than other mobile phones at the same price.
In addition, iQOO Z7 also has a full-featured NFC and 3.5mm headphone jack, and it is also the first mobile phone in the iQOO Z series to be equipped with an infrared remote control sensor.
Overall, iQOO Z7 has embarked on a road of extended battery life and second charging for 1.5K mobile phones. The Snapdragon 782G mobile platform and the X-axis horizontal linear motor also allow the mobile phone to enjoy quality close to the flagship mobile phone, the Gaming experience.
