Xiaomi’s offshoot Redmi has finally launched its most anticipated K40 series. As every year, the smartphones focus on seamless performance and speed.
The Redmi K40 series consists of three handsets: the Redmi K40, the Redmi K40 Pro and the Redmi K40 Pro plus. As expected, all three handsets use Snapdragon 800 series chipsets. The Vanilla K40 ships with the brand new SD870 SoC, while the other two phones are powered by the flagship SD888 platform for mobile devices.
Display and Design
The K40 trio share similar aesthetics and display specs. In terms of design, in addition to the additional sensors on the camera, they have a Mi 11-like design. Each model is available in three color options: Bright Black, Dreamland and Sunny Snow.
The phones are based on a 6.67-inch E4 AMOLED panel from Samsung with a resolution of 1080 x 2400, a refresh rate of 120 Hz and a touch sampling rate of 360 Hz, one of the highest ever.
Storage and Specs
Internally, the vanilla Redmi K40 is powered by the Snapdragon 870 which is a revamped version of last year’s SD865 with the speed of its prime core cranked up to 3.2 GHz. In terms of storage, it offers 6 GB, 8 GB or 12GB of RAM and 128 GB or 256 GB of onboard storage.
The other two phones in the series are powered by the Snapdragon 888 mobile platform that runs in combination with 12 GB of RAM and 256 GB storage on the Pro+ model. The Redmi K40 Pro offers storage specifications similar to the vanilla Redmi K40 except for the 12GB RAM variant.
The software front is handled by MIUI 12 flavored Android 11. In terms of connectivity, the Pro and Pro+ lack mmWave 5G, but they do have Wi-Fi 6E, which can reach speeds up to 3.5Gbps. The Redmi K40 comes with Wi-Fi 6 (non-E) compatibility. Moreover, as compared to the vanilla K40 that comes with BlueTooth 5.1, both the Pro models pack BlueTooth 5.2. All three phones come with Hi-Res Audio Wireless certification for BlueTooth.
Cameras
The Redmi K40 Trio has a similar configuration of the triple sensor camera. However, the primary sensors are the differentiating factor. The K40 Pro + is equipped with the 1 / 1.52-inch sensor Samsung ISOCELL HM2 with 108 MP. It also provides support for 9-in-1 binning. The free sensors are an 8 MP ultra wide angle camera (119 °, f / 2.2) and a 5 MP telephoto macro.
Price and Battery
All three models are powered by a 4,520 mAh battery that charges up to 33 W via USB-C using standard protocols. It supports USB Power Delivery 3.0 and QuickCharge 3.0+. According to the company, the charging process is optimized so that the battery goes from 0% to 100% in just 52 minutes.
