What CompareTab says about Xiaomi 15T vs Xiaomi Redmi K90 Ultra
Xiaomi Redmi K90 Ultra offers more RAM, storage, battery capacity and a smoother display than 15T, with 16 GB of RAM versus 12 GB, 512 GB of storage versus 256 GB, a 8550 mAh battery versus 5500 mAh, and a 165 Hz display instead of 120 Hz. It also adds an ultrawide rear camera and 100W charging. Xiaomi 15T, however, is lighter at 194 g versus 227 g and thinner at 7.5 mm versus 8.18 mm and has a higher-resolution 32 MP front camera. The main trade-off is Redmi K90 Ultra’s extra RAM, storage, faster charging, battery capacity, and smoother display versus 15T’s lighter, thinner build and higher-resolution front camera.
