We are looking at a 4,520mAh cell across the lineup with fast charging up to 33W via USB-C that leverages regular USB Power Delivery 3.0 and QuickCharge 3.0+. The battery is said to go from 0 to 100% in around 52 minutes thanks to the charging optimization used.
For connectivity, the devices support sub-6 GHz 5G, Wi-Fi 6, Bluetooth 5, NFC, and IR blaster. These even get Dolby Atmos and Hi-Res Audio certification for the greater audio experience though lack a 3.5mm audio jack. Interestingly, all of these devices have an X-axis linear motor that is used for haptic feedback.
Meanwhile, the K40 lineup is IP53 rated for dust and water resistance. The screen lies beneath a Gorilla Glass 5 layer, however, the fingerprint scanner sees its place embedded in the power button at the side.
Here we will look at each device from the Redmi K40 series in brief followed by price and availability.
