Poco is set to officially unveil the M8 on January 8, and ahead of the launch, the company has shared additional specifications for the device.
The M8 features a 6.77-inch 3D curved OLED display with a resolution of 1080x2392, a 120Hz refresh rate, and an impressive peak brightness of 3,200 nits. Poco claims this is the "most durable 3D curved display phone" in its category.

It is MIL-STD-810H certified, ensuring resilience against extreme temperatures, dust, shocks, and the unpredictability of daily life. Additionally, the M8 boasts an IP66 rating for dust and water resistance and features Wet Touch 2.0 technology. The device has also undergone drop tests from heights up to 1.7 meters.
With its incredibly slim profile of just 7.35mm and a lightweight design at 178g, the M8 is the slimmest and lightest device in its category.

Besides the officially disclosed specifications, recent retailer listings indicate that the M8 will be powered by the Snapdragon 6 Gen 3 SoC. The camera setup includes a 50MP main sensor, a 2MP depth sensor, a 20MP front-facing camera, and a 5,520 mAh battery that supports 45W wired charging.
