Sleek and Modern Design
The POCO F4 has a kinda sleek design that feels modern enough, for a premium device, I mean.

The POCO F4 arrives with an IP53 rating for water and dust resistance, so it can handle a few splashes and still, keep dust entry somewhat under control.

However, Snapdragon 870 on POCO F4 still delivers good performance when it clocks up to 3.2 GHz, along with highly fuel-efficient and non-overheating usage unlike Snapdragon 8 Gen 1 chip at the latest nowadays. This is regarded as the strongest midrange smartphone in the present time.

The whole hardware package is supported by extra things like 4K video recording, smart functionalities, and a punch hole 20MP selfie camera sitting at the front , so overall the device stays flexible for day to day capture.
