Reviews for the Xiaomi Redmi K90 Max

Review: Is REDMI K90 MAX the Ultimate Gaming Phone in 2026?
Source: Igeekphone English

Thermal performance further reinforces its gaming focus. During testing with demanding titles like Honkai: Star Rail, surface temperatures remained controlled, with peak readings under 40°C when the fan was active. Disabling the fan caused temperatures to rise quickly, highlighting how effective the cooling system really is. Battery life is another strong point. The massive 8550mAh battery supports long gaming sessions without frequent charging interruptions. In stress tests, the device delivered up to 18.5 hours of heavy usage, which is exceptional for a performance-focused phone. The addition of bypass charging also helps reduce heat during charging while gaming, extending battery health over time.
