OnePlus 7T is an upgraded version of OnePlus 7, from the point of view of appearance, there are obvious changes on the front and back, the front screen is elongated from 19.5:9 to 20:9, and the back is upgraded from the main camera and depth of field dual camera to the main camera, ultra-wide angle plus telephoto triple camera combination, and surrounded by a circle. The Oreo triple camera on the back of the 7T is somewhat similar to the Huawei Mate 30 Pro and vivo NEX3, but it is a horizontal triple camera in the circle, and the look and feel is not as coordinated as the latter two. As for the problem of the camera module protruding from the fuselage, the official protective case can smooth out the gap very well, and the impact on the hand feeling is not very great.
In terms of workmanship and materials, the OnePlus 7T is better than the Reno Ace and Realme X2 Pro, which are respectively reflected in the articulation of the front panel and the middle frame, and the OnePlus 7T will be smoother; The left and right bezels of the 7T screen will also be a little narrower; The back cover of the fuselage is made of AG matte glass, while the other two models are glossy glass.
The OnePlus 7T and 7T Pro are different in that they don't use a curved screen, but the same 90Hz straight screen as the Oppo Reno Ace, and the Realme X2 Pro uses the same screen. The screen quality of the three is generally similar, with a resolution of 2400×1080 and a converted Pentile arrangement PPI of 328. The comprehensive quality of this screen is really outstanding in FHD screens, using Samsung's latest light-emitting materials, local peak brightness can reach 1000 nits, and it supports HDR10 video playback.
In terms of color accuracy, the OnePlus 7T will perform a little better than the other two models, with the average DeltaE of the 7T not exceeding 2 in standard mode and no more than 3 in the other two models, but no obvious color difference is felt in daily use. All three models have a 90Hz refresh rate, but OnePlus's system optimization is a little more complete than the other two, the Reno Ace has had the problem of broken touch and touch delay in the early stage, and the Realme X2 Pro has had the problem of frame drops, after a series of system updates, the difference between the three has been much smaller. When both the Reno Ace and Realme X2 Pro are upgraded to ColorOS 7, the smoothness should be a little more stable.
In terms of performance, the gap between the three is even smaller, both are Snapdragon 855 processors, and all are UFS 3.0 flash memory, but it is worth noting that the Realme X2 Pro uses UFS 2.1 flash memory at the lowest configuration. The three models use different cooling schemes, but the heat of the body during gaming is similar, basically at the same level.
In terms of photography, the main camera of the OnePlus 7T is IMX586 with optical image stabilization, the Reno Ace is also IMX586, but there is no optical image stabilization, and the X2 Pro is Samsung S5KGW1, 64 million pixels, without optical image stabilization; The ultra-wide angle of the 7T is the IMX481, while the Reno Ace and X2 Pro are the IMX319; The telephoto of the three models is S5K3M5, and the Xiaomi Mi 9 also uses this telephoto, which is a very mature product.
In daily shooting, among the three models, the OnePlus 7T is the most stable, with more accurate white balance during the day, the most realistic color reproduction, and the timing of automatic HDR in night shooting is also more timely. For night imaging, the OnePlus 7T has the largest F1.6 aperture and optical image stabilization among the three, and detail preservation is better, but some dark details will appear darker, and there is still room for optimization.
Maybe many new users of OnePlus in China don't know much about it, hydrogen OS is an operating system characterized by smoothness. In terms of the richness of functions, it is not as good as other domestic manufacturers, but after gradual optimization in recent years, it is far from "simple", but OnePlus needs to think about how to balance between function and lightness, which does not lose its own characteristics, but also takes care of the needs of new users.
In terms of charging range, the OnePlus 7T is indeed the weakest of the three 90Hz models, with the Reno Ace and X2 Pro both having 4000mAh batteries, and the OnePlus 7T only having 3800mAh. Reno Ace comes standard with 65W gallium nitride fast charging, which only takes 26 minutes to fully charge, X2 Pro comes standard with 50W fast charging, which is only 2 minutes slower than Reno Ace when fully charged, OnePlus 7T's 30W fast charging is a relatively normal performance in the 3000 yuan model, and it takes 56 minutes to fully charge.
