Snapdragon 870 is the processor of choice in this device, Qualcomm’s new high-end chip. A chip that gives a great performance to the phone,Somewhat lower than Snapdragon 888, which is what we see in the K40 Pro and the Pro +. In addition, the use of Snapdragon 870 allows a more adjusted price on the device, but it also endows it with 5G. Along with the chip we have various combinations of RAM and storage.

As for cameras, the main sensor varies depending on the device. The Redmi K40 has a main 48 Mpx, the K40 Pro one with 64 Mpx and the Pro + leaves us with one with 108 Mpx. The other two sensors are kept in all of them: an 8 Mpx ultra wide angle and a 5 Mpx telephoto. The most advanced of all, the Pro + also leaves us with double ISO for dynamic range.

The battery will be another highlight in this range, with the K40 having a 4,520 mAh capacity battery, with 33W fast charging in addition. As an operating system, the full range uses MIUI 12 with Android 11 as standard, so they have all the functions that we discussed recently.
