Redmi today in China, announced the K40 series which has three models – the Redmi K40, the Redmi K40 Pro, and the Redmi K40 Pro+. The base model, the Redmi K40 comes as a flagship killer and a challenger to the Motorola Edge S. It packs an impressive display, a flagship processor, and a price tag that leaves you wondering if you really need to get a high-end flagship this year.

Redmi K40 Launched

Redmi K40: The latest flagship killer With 120Hz AMOLED display, Snapdragon 870, 48MP triple rear cameras for just $310

Design

The Redmi K40 has almost nothing related to its predecessor. It drops the pill-shaped right positioned punch hole for a centered one. It also switches the design on the rear to one that is similar to that of the Mi 11 and with fewer camera sensors than the Redmi K30. Redmi has also managed to make it thinner and lighter even though it packs a tiny bit bigger battery.

Performance

It performs better than the processors. The 60Hz IPS LCD display is gone and in its place is a 6.67-inch E4 AMOLED True Tone display with a 120Hz refresh rate and a 360Hz touch sampling rate. The display has a DCI-P3 color gamut, HDR10+, and a maximum brightness of 1300 nits. It also has MEMC and is covered in Gorilla Glass 5. For those concerned with the size of the hole, Redmi says it is 2.76 millimeters.
