Poco has two mid-range smartphones in the F4 and X4 GT models. The naming differentiation is complicated by the fact that there is also the F4 GT, which is more expensive and offers more performance.
What the F4 and X4 GT have in common is the camera setup – at least at the back. Both offer a 64MP main camera that works well in our review. The results of wide-angle and macro lenses are less impressive. The images are usable, but the quality is clearly lower than that of the main lens. On the other hand, there is a difference up front. While the F4’s camera has a 20MP resolution and takes nice selfies – although lens flares do occur in backlighting – the manufacturer uses a 16MP camera in the X4 GT.
The main differences between the devices are the screen and the installed SoC. The F4’s 6.67-inch screen is slightly larger than the X4 GT’s 6.6-inch panel, but it’s primarily the proven technology that makes the difference. The F4 is equipped with an OLED display that shines to perfect black levels thanks to its design. The screen is also dazzling with a decent brightness of 1274 nits under test, while the refresh rate reaches a maximum of 120 Hz. The X4 GT delivers up to 144Hz, but technically uses an LC screen. Poco sets a maximum brightness of 500 nits here.
The F4 is powered by Snapdragon 870 with Adreno 650 GPU. Although the SoC is not brand new, it ensures solid performance in the smartphone. Even current games can be played at high settings. On the other hand, the X4 GT relies on the power of the MediaTek Dimensity 8100 in conjunction with the Mali-G610 MC6 GPU. Both come with UFS 3.1 storage, with a capacity of 128 or 256 GB, depending on the version. The F4 has 6GB of RAM in the mini version, while the X4 GT has 8GB in both versions.
Technology and journalism have always come together in the past. However, it was mostly cars and motorcycles that put her under the microscope. Since my active triathlon days, I’ve been a fan of sports watches and smartwatches – the triathlon is history for me, but the enthusiasm for the watches is still there. That’s why, in parallel with my theology thesis, I write in Notebookcheck mainly about smartwatches, but also about other news and technology that interests me.
Growing up in regional Australia, I was first introduced to computers in my early teens after I broke my leg from a soccer (soccer) match that doomed me temporarily to a more inward-looking lifestyle. Shortly thereafter I was building my own systems. Now I live in Germany, having moved here in 2014, studying Philosophy and Anthropology. I am particularly intrigued by the way computer technology has radically and dramatically reshaped human culture, and how it continues to do so.
