The new Redmi K40 devices come with an updated design, which is a far cry from the Redmi K30 lineup from last year. Instead of a center-aligned camera island, the new devices feature a left-aligned rectangular camera island that resembles the one found on the Xiaomi Mi 11. They feature new back panel finishes, and the Redmi branding has also been moved to a new position closer to the left edge. Things aren’t all that different over on the front, except for the new centered hole-punch cutout for the selfie camera.

The vast majority of the changes on the Redmi K40 series can be found on the inside. The new devices come with updated SoCs, with the Redmi K40 packing Qualcomm’s new Snapdragon 870 chip and the Redmi K40 Pro/Redmi K40 Pro+ featuring the flagship Snapdragon 888 chip. The SoCs are paired with up to 12GB of RAM and 256GB of storage on the non-pro variant, with the Pro and Pro+ variants also getting up to 12GB of RAM and 256GB of onboard storage.

Redmi K40 Pro

The Redmi K40 features a 6.67-inch FHD+AMOLED display with a peak refresh rate of 120Hz and a touch sampling rate of 360Hz. It has a single hole-punch cutout for the selfie camera and minimal bezels on all sides. The Redmi K40 Pro and the Redmi K40 Pro+ also feature the same display. All three devices feature a substantially large 4,520mAh battery. All three devices also feature a proper stereo-speaker setup, with a speaker each on the top and bottom edge. This isn’t to be confused with the pseudo-stereo speaker setup that we’ve seen on some devices in the past, which uses the earpiece as a secondary speaker.

Redmi K40 Pro+

The Redmi K40 series has received some major improvements on the camera front. The Redmi K40 Pro now features a triple-camera setup with a 64MP primary camera, an 8MP secondary camera, and a 5MP tele-macro sensor. The non-pro variant features a triple-camera setup with a 48MP primary camera, an 8MP secondary camera, and a 5MP tele-macro camera. The Redmi K40 Pro+ features the most impressive camera setup, with a 108MP primary sensor, an 8MP secondary camera, and a 5MP tele-macro camera. On the software front, all three devices run MIUI 12 based on Android 11.
