Frequently asked questions

Answers drawn from this model’s datasheet.

The POCO X8 features an 8340 mAh battery, almost double the market median of 4500 mAh. This capacity earns it a battery score of 95/100, rated as very long. You can expect several days of regular use without recharging.

At 6.83 inches, this AMOLED display slightly exceeds the market median of 6.7 inches. With dimensions of 163.45 mm height and 78.27 mm width, the POCO X8 falls into the large smartphone category, difficult to operate entirely with one hand for most users.

The 256 GB internal storage sits below the market median of 384 GB, earning a score of 58/100 rated as limited. This capacity suits moderate usage, but may fill up quickly if you take many high-resolution photos and videos.
