The Xiaomi Redmi K90 Max suits buyers seeking the faster display and much larger battery; the Redmi K90 is easier to carry and adds a telephoto camera. The overall gap is narrow, so the choice rests on that priority.
The K90 Max has a 6.83″ display versus 6.59″, with 165Hz versus 120Hz and 447ppi versus 419ppi.

The Redmi K90 weighs 206g versus 227g, however, and its 4.47GHz maximum clock is higher than 4.21GHz.
The K90 Max battery is 8,550mAh versus 7,100mAh, a capacity well above the usual level; both phones charge at 100W. For cameras, the K90 Max has an f/1.7 main aperture versus f/1.9, while the Redmi K90 adds a telephoto camera that the Max lacks.
