Xiaomi will be launching the Redmi Note 7 Pro in China on March 18 and ahead of that date, the company has started teasing some of the outstanding features the device would pack. The Redmi Note 7 Pro has already been launched in India but the China version may come with a few surprising features that were absent on the India version. While we wait to see some of those features, the Chinese tech giant has officially disclosed that the Redmi Note 7 Pro comes with the hydrophobic P2i nano coating.
In case you don’t know, P2i is a nanotechnology development company that works with manufacturers to produce liquid repellent nano-coating protection to products for the electronics, lifestyle, life sciences, filtration and Energy, and military and institutional sectors. The P2i technology employs plasma-enhanced chemical vapor deposition processing to apply an ultrathin polymer layer onto all surfaces of a product. The process known as ‘pulsed-plasma’ takes place under low pressure within a vacuum chamber at room temperature. The coating is introduced as a vapour and ionized. This allows for the development of the polymer layer, which forms a covalent bond with the product’s surface, making it extremely durable. Further, the coating is one thousand times thinner than a human hair and so it does not affect the look or feel of products. It confers on the device hydrophobic properties but may not prevent smudge and fingerprints from accumulating on the screen.

The nanocoating on the Redmi Note 7 Pro isn’t only on the screen but on the entire body since the device also has a glass back. The Redmi Note 7 Pro doesn’t come with any IP rating for water and dust-resistance but the P2i nano-coating makes it splash proof. The premium mid-range device also come with hardware optimisations such as rubberised layering around important modules to make the phone sort of waterproof. You don’t want to get the phone inside water, though,
