Alongside the Redmi K50 & Redmi K50 Pro, the company also launched a third phone under the “K” series. It is not a phone under the K50 series but rather under the last year’s K40 series. It is named the Redmi K40S. As the name suggests, it is a small upgrade over the Redmi K40 of last year. Also, naming-wise, this is the successor to Redmi K30S, which launched in 2020 as a rebranded Mi 10T.

Redmi K40S

Compared to the Redmi K40, the design is completely different this time. The K40S gets flat sides and a similar camera module design as the K50 series. The fingerprint scanner is still present on the side. Speaking of the similarities, Redmi K40S has the same 6.67-inch E4 AMOLED with a 120Hz refresh rate and FHD+ resolution. The panel is protected with Gorilla Glass 5 and has a peak brightness of 1300 nits. It supports HDR10+ as well.

There is Snapdragon 870 SOC under the hood that is paired with LPDDR5 RAM and UFS 3.1 storage.

Even the camera setup is almost identical. There is a primary 48MP Sony IMX582 sensor, an 8MP ultrawide, and a 2MP macro (instead of 5MP). One major difference is that the K40S has OIS for the primary camera, something that was not present on the K40 of last year. There is a 20MP selfie camera.

The battery size is almost the same at 4,500mAh, but the charging speed gets an upgrade as it is now 67W as compared to 33W. The phone is just 7.7mm thick and weighs around 195g. There are stereo speakers with Dolby Atmos, and MIUI 13 runs out of the box.

So, the Redmi K40S has fast charging, a new design, and OIS for the primary camera. Everything else remains the same as Redmi K40. There are four storage options and here is the price –

  • 6GB + 128GB – ¥1799 (~$283 / ₹21,500)
  • 8GB + 128GB – ¥1999 (~$315 / ₹23,900)
  • 8GB + 256GB – ¥2199 (~$346 / ₹26,500)
  • 12GB + 256GB – ¥2399 (~$378 / ₹28,699)
