Less than half a year later, one plus 3T has been released. The most important upgrades are Snapdragon 821, battery capacity and 16 megapixel front camera, followed by gun gray and 128G versions. The core issue of this evaluation is the performance, endurance and front-end improvement, as well as the difference between these changes and 200 yuan.
parameter
Appearance and workmanship
One plus 3T is only one more corner mark than one plus 3. The packaging box comes with a mobile phone bracket. The texture and design are very careful. There are brand stickers rarely found in domestic mobile phones in the accessories, as well as pins, instructions, Dash flash charger and special Type-C data cable.
Dash fast charging is a high current scheme, and the maximum nominal output of the charging head is 5V4A. Like OPPO's VOOC flash charge, it is a customized scheme, and fast charge cannot be performed without any one (only 5V2A).
Left one plus 3, right one plus 3T
The appearance is familiar. The only visual difference on the front is that the front camera coating has changed from blue purple to green. The home key that cannot be pressed is a ceramic cover plate, and the color is slightly different from the screen glass.
Hexahedral details of one plus 3 and one plus 3T
The new gun gray is darker than the silver gray of one plus three, with a slight wine red color. The light and shadow contour changes at different angles are more obvious. It is more low-key but more pretentious, which means this effect
The most obvious feature on the side is the three-stage scenario selection button (or mute key) similar to the iPhone, which is used to quickly switch between "mute, don't disturb and ring modes" (the latter two cannot completely turn off the sound). Users who often have meetings or classes may prefer it.
Workmanship&feel&fingerprint identification
The following is consistent with one plus three, and is generally summarized as follows:
work Excellent, even and tight seams, almost no empty keys, and the pressing feel is tight and hard;
feel On the middle side, the back waist line slightly touches the hand, but the width and back radian are properly set;
fingerprint identification The speed is still the fastest front fingerprint recognition machine except vivo X9/OPPO R9 series. The home key has a long press/double click function, which can be used as a shortcut to turn on the camera and turn off the screen. It is highly practical. What's more special is that the system comes with the multi task and return keys on both sides, both of which have double click and long press functions, leaving a lot of customization space.
screen
Parameters: Both One Plus 3T and One Plus 3 use 5.5 inch 1080P Optical AMOLED screens, which are supplied by Samsung. The most obvious feature is that the manual maximum brightness is much higher than other AMOLED screens. There is no automatic brightness burst mode, but the brightness will increase when the display area is smaller (a feature of AMOLED screen).
Limit brightness: The maximum manual brightness is 431 nits (the one plus three in our hand is 450 nits), and the maximum small area display is 586 nits. This brightness level is very close to IPS, and readability in the sun is not a problem.
Brightness uniformity: The brightness of the four corners of our testing machine is 480/497/429/416 nits respectively. The brightness at the top is nearly 80 nits higher than that at the bottom. The uniformity performance under the extreme brightness is not very good. When the center is 100 nits, the brightness difference is below 15 nits, and the performance is acceptable.
Color temperature/gamut: The default color temperature of the screen is 7741K, which is normally cold; 111 Nite, It reaches 145% of sRGB color gamut, with bright hair and relatively high blue saturation; The total gamma value is 2.26;
Color accuracy: Default mode at 100 nits, The average deltaE of 104 colors is 5.9, the maximum is 12.9, and the color accuracy performance is still not very good. The data of "one plus three" in our hands are 4.9 and 11.9 respectively. For comparison, iPhone 7 is 1.6, Note5 is 1.8, S6 edge+is 2.6, and S7 edge is 2.9.
Summary: Many fans demonized the one plus three screen before, probably because of the screen's individual differences. Admittedly, in addition to the amazing brightness, it is a 1080P Pentile arranged AMOLED screen with poor color accuracy, partial batches may tend to be red, and average uniformity, but there is no essential difference between the overall level and AMOLED screens of machines at the same price.

Key and application management
Background: When one plus three was released on June 15, it was equipped with domestic customized hydrogen OS, which is very close to the original OxygenOS (oxygen OS) in foreign countries. On August 23, the open test of hydrogen OS 2.5 began to move closer to the rear, and the system functions began to move closer to the original system.
model: One plus 3T code is A3010 (one plus 3 is A3000), which is equipped with the hydrogen OS 2.5 system based on Android 6.0.1. However, only a few items in the setting menu have different names, icons, and order with visible differences. At the deadline of December 2, it was the version on November 22, six days later than the latest version of One Plus Three.
Fluency: It is the only system in the domestic ROM that has the same logic and fluency as native Android. Sliding, application loading, switching and animation are very straightforward. In addition, this is also one of the few systems that are very relaxed in background management, which improves the speed of its multi task switching, but causes the standby power failure problem mentioned later;
Features: Although the original biochemical system has been simplified, the hydrogen OS2.5 is still a very unique system. The desktop plug-in aggregation center on the left side of the desktop, the unfixed dock bar, the pure black theme, the rich button customization, the rest screen and body gesture are all very special or practical functions. It has link control, but advanced functions that are important to users, such as self startup and permission control, are now taken in deeply, which is not as local as the old system. The author also misses the pull-up control bar before
Readers who are interested in the details of the new and old systems or this system can view the detailed comparison before Original Biochemical Backward - Comparative Evaluation of Hydrogenation OS 2.5 System , I will not repeat it here.
performance
Configuration description: One plus 3T is equipped with the flagship "standard" Snapdragon 821 in the second half of 2016, a full blood version. The Kryo size core of the CPU part has increased from 1.59+2.15GHz of the Snapdragon 820 to 2.19+2.34GHz, and the GPU has increased from the original 624MHz to 653MHz.
Comparison object: We compare the hammer M1L, Asus Zenfone 3 Deluxe (Zunjue) and Xiaomi MIX, which are the same as the full blood version of Snapdragon 821, with the one plus three, Samsung S7 edge and LG G5 of the conventional Snapdragon 820.

GPU graphics performance test
Flash memory read/write speed test
CPU play: One plus 3T CPU regulation is very active, and the actual results are very overbearing. Except GeekBench's multi-core performance is better than using white list, and the temperature controlled hammer M1L, the rest of the scores are the highest in the active 821;
GPU play: The performance was not as good as expected, on the same level as 820 machines such as One Plus 3 and S7 edge, and not as good as the other two full blooded 821 models;
Storage plays: In terms of random write performance, the use of the f2fs file system has increased more than three times. However, other achievements were not as good as expected. The 128G version we got should have better flash memory performance than the 64G model (the same flash memory, the larger the capacity, the faster the speed), but the addition of 3T did not distance us from them. In practice, it may be that the commissioning of the new machine has not yet been completed. The 128G version of One Plus 3T, which should have been faster in our hands, cannot be separated from the 64G version of One Plus 3 in terms of smoothness and application startup speed.
Frequency and core scheduling
One plus 3T and the Snapdragon 821 of Asus Zenfone 3 Deluxe are both similar in regulation. Only when the application is opened and loaded, the 4-core maximum frequency will break out. Occasionally, the Snapdragon 821 will be full of blood to improve the experience of multi task use. In addition, the "small core" of one plus 3T in the application cannot reach 2.19GHz. Its special point is that its daily frequency reduction/temperature control threshold is already at the level of the Hammer M1L white list, which can be maintained at 1.6+2.34GHz for a long time, and its daily play has been at the same level as the Hammer running mode:
One plus 3T application startup and application internal frequency monitoring
Once you add 3T, as long as the application is opened and loaded, it can have a 4-core maximum frequency in a few seconds. If you keep on "opening applications - returning to the desktop - opening other applications", even if the body temperature is slightly higher, even if the 4-core occupancy rate rises to 95%, it can be maintained at the 4-core maximum frequency (2.19+2.34GHz);
However, it can only run at 1.6+2.34 GHz in applications, and the small core limit will be limited to 1.6 GHz. Even in GeekBench's multi-core test, the multi-core score of one plus 3T is 1.6+2.34GHz. In GeekBench's white list of Hammer M1L, M1L can be 2.19+2.34GHz (and the temperature control is released), which is why only here can't beat Hammer M1L with 3T;
Hammer M1L running split frequency monitoring
At present, the only true · full blood Snapdragon 821 recorded by the score application is only the M1L in the multi-core test of several famous test apps, such as GeekBench and Anthare, whose GeekBench multi-core score is about 4760 (one plus 3T is only 4440, and Zenfone 3 Deluxe is 4410);
Another conclusion is that the True Blood Snapdragon 821 is really a big stove. Even if it is full of blood when the application is opened and loaded, the machine can feel the obvious temperature rise within more than one minute after 20 applications are opened continuously
photograph
One Plus 3T uses sapphire lenses, but the rest of the camera system remains unchanged. It is still optical anti shake+Sony's 16 megapixel IMX298 sensor, which supports phase focusing.
Photo experience: The software performs well. Its shutter response and imaging speed are very fast. It supports automatic HDR and automatic night view functions, and has HQ pixel optimization function, which can improve discrimination and weak light performance. HDR algorithm processing is carried out in the background, which is hard to detect at ordinary times, but when 4 or 5 consecutive shots are taken in HQ mode, it will prompt that processing is in progress, which will affect the use in some occasions (only 7 or 8 consecutive shots of the old version system will prompt).
Focus: This system had a good experience in the big environment at the beginning of the year. Until now, it has been a long way away from the non flagship aircraft camp. However, half a year after IMX398/386/378 and a large number of replacement sensors were launched in succession, the one plus 3T, Xiaomi 5 and other machines equipped with IMX298 are relatively weak in focusing speed and success rate, which is mainly reflected in the decline in focusing success rate of extremely weak light.

Imaging characteristics, No matter the photographing experience or imaging characteristics of One Plus 3T are the same as those of One Plus 3. For details, you can find the previous photographing evaluation on Aigoji WeChat or the official website. Here is a brief summary:
From white balance/metering/tolerance/saturation to discrimination/noise control/texture, there is no noticeable difference, It seems that the addition of sapphire glass has no obvious impact, If it were not for exif information, it would be impossible to separate the sample of two machines;
Wide angle is 28mm equivalent focal length, lens quality is good, anti glare and edge degradation control performance is good;
HQ mode can effectively improve the control and discrimination of noise points. The light measurement is accurate in the daytime, the dark light is slightly underexposed, and the indoor light white balance is warm, which is more pleasing to the eye;
In the daytime, the discrimination is medium to high, and the noise control and discrimination of light and weak light scenes are excellent.
Although the image of one plus three is still strong, the image of one plus three is still strong, but after the arrival of a large number of new sensors, the advantage of IMX398/378/386 is not as great as it was in the middle of the year.
Front photo
Detail magnification
Configuration and expectation: One plus 3T front camera has changed from the original 1.4 μ m large pixel scheme of 8 million pixels to the current 1 μ m high pixel scheme of 16 million unit pixels. Theoretically, the weak light imaging performance will decline.
Actual performance: This sensor is unexpectedly strong. Even if the ISO is higher in the same environment when adding 3T, its discrimination and noise control in the indoor lighting scene will be completely rolled over when adding 3. Even if it is not magnified, there will be a clear gap.
Algorithm and shot problem: Unfortunately, the one plus 3T algorithm seems to have not been adjusted well: it has an obvious tendency to overexpose, and it is easy to lose bright details; The white balance is not very stable, yellow, and the color is not very pleasing; Its lens quality seems to be slightly weaker than that of one plus three, and the pressure will be greater when fighting against backlighting;
Application function: Yijia's camera app has only one beauty adjustment option, and the functions like "thin face, big eyes" that female users like have not been added, so users can only use third-party applications instead.
In general, the author is still positive about the upgrade of the front camera. Although the software algorithm is not complete, the quality of the hardware has been greatly improved. After all, the front camera and the rear camera are different, and the algorithm problems can be easily solved with a third-party beauty camera, with low remediation costs.
Whether the front camera needs discrimination or not, the attitude of the author is still the same as when the iPhone 6s front pixel was upgraded: pixels and imaging quality are also required for beauty and skin abrasion. The details actually photographed can be smoothed, but the details not photographed can not be repaired by any algorithm.
Endurance&Charging&Heating
The battery of one plus 3T has grown to 3400mAh. After 30 minutes of large-scale games (NBA 2K15), 30 minutes of wifi and 4G Internet access, 1 hour of music playing and 30 minutes of local video playing, a total of 3 hours of endurance testing, the remaining power is 75%.
The overall endurance of One Plus 3T is significantly improved than that of One Plus 3, and each link has been improved to different degrees, finally catching up with the endurance performance of the mainstream 820 and 821 flagship. Its CPU utilization is low in 4G and WiFi Internet access, video and other links. Benefiting from the power consumption bonus of 1080P AMOLED screen, the power consumption is lower than that of similar models, which improves the endurance performance.
Standby problem: One plus three is the screen and endurance that are blacked most. The impression of endurance is mainly due to the high standby power consumption. In the evaluation, its performance is average, because the comparison object is The 820 of the same generation, but in front of the 810 of the previous generation, even the 1000 yuan aircraft now, the endurance is also commendable. but The power failure rate of one plus 3T wifi network standby for 8 hours is about 5-6% (similar to that of one plus 3), and this is still the case when WeChat is not logged in. This is a problem that other domestic ROMs will not have.
The main reason may be that the hydrogen OS is closer to the background control of the native system. By default, its background clearing will not completely clean up applications (as shown in the above figure, the setting can be changed in "Other Advanced Settings - Multi task Clearing Method"). Applications often "reside" in memory, which can speed up the next startup, but also increase the standby power consumption of the system.
The Dash flash charge equipped with the One Plus 3T and the VOOC flash charge of OPPO can be mixed with their charging heads and wires, both of which are high current schemes, and support the output of 5V4A nominal:
From 5% to 100% charge with one addition of 3T, charge from 15 minutes to 33%, 30 minutes to 61%, 45 minutes to 85%, and one hour to 94%;
Trickle charging starts from about 90%, and the last 6% of the power takes 25 minutes. It takes a total of 1 hour and 25 minutes to fully charge, which slows down the last performance, but the overall charging speed is excellent.
summary
Respond to the improvement points at the beginning, one plus 3T The newly introduced gun grey and 128G versions are designed to cater for the tastes of more users, and the core part, except for the camera, Both have improved to a certain extent:
The improvement of Snapdragon 821 can hardly be seen in the application opening speed and multi task switching It mainly affects the service life of the machine, 1、2 Years later, the operation“ Bloated System and application will be more obvious;
The battery growth of 400mAh, combined with the Snapdragon 821 with better "physique", has significantly improved the endurance, but the problem of fast standby power down is still the same, and we have to wait for the system update to fill the hole. Users with computer experience can use the forced Doze function of apps such as Green Guard to optimize;
The front camera has significantly improved in pixel, detail and noise control. Although the lens quality and algorithm optimization have not been in place, the shortcomings do not outweigh the shortcomings;
One plus 3T is a truly improved version, and the core experience has not changed much. When the hardware level reaches the top level, the weakness of the system will be highlighted. The situation is a bit like one plus two when it was just launched. The current hydrogen OS 2.5 has pulled the back leg of core improvements such as processors, batteries and cameras to varying degrees.
Back to the perspective of normal users, One Plus 3 is already a very bucket type machine. At the price of 2499, it is still very competitive after six months. One plus 3T standing on the shoulder of one plus three has successfully filled the hole of endurance and front end. but Augmentation After price increase , it is more like an extra parallel to one plus three Option.
