While dual sourcing sometimes raises concerns about panel quality, manufacturers typically calibrate both versions to ensure consistency.

The screen can hit a peak brightness of 3200 nits with 800 nits of typical brightness and up to 1800 nits in high-brightness mode. Redmi is also using a FocalTech touch controller to ensure accurate and responsive touch performance.

Under the hood, the phone runs on the powerful MediaTek Dimensity 9400+ chipset paired with a D2 discrete GPU. It uses fast LPDDR5X RAM and UFS 4.1 storage. Cooling gets a major upgrade here, too. Redmi has included its largest-ever 3D Ice-Sealed Circulating Cooling Pump, which features a dual-level raised structure and a 6500mm² LHP area. Xiaomi claims it helps reduce core temperatures by up to 3°C.
