The devices are made up of more durable glass cover with a nice gold finish which is achieved with an atomic level process, precision machined, surgical grades stainless steel bands which provides a new level of dust and water resistance in the iPhone industry.

And talking about water and dust resistance; The iPhone XS and iPhone XS MAX are rated IP68 (maximum depth of 2 meters up to 30 minutes) under IEC standard 60529, while the iPhone XR is rated IP67 (maximum depth of 1 meter up to 30 minutes) under IEC standard 60529 which is the same as the iPhone X.

The three devices support dual SIM card (nano-SIM and eSIM): what is eSIM? eSIM stands for “embedded SIM” (also called eUICC). It's a standardized SIM chip open to multiple mobile operators globally. Meaning, if you have an eSIM you don't have to replace one SIM card with another when switching carrier. ... GSMA is an association representing the interests of mobile operators worldwide.

We have seen the power of the A11 Bionic chip on iPhone X, iPhone 8 & 8 plus right? now it has a new boss in the industry, A12 Bionic chip with the next generation Neural engine which is as at the moment, the most powerful chip in the apple smartphone industry. It is said to use a real time learning to convert the way users experience gaming, photos and more..

The devices features 4-core GPU with a higher performance than the one on iPhone X and i know you must have been wondering what the "neutral engine" does maybe, well it job is to perform real time machine learning for the purpose of making predictions, learning of patterns and so on.
The Neural Engine is said to be very fast, able to perform up to five trillion operations per second with 8-core architecture and Core ML runs Up to 9x faster than A11 Bionic chip.

really? dual sim? lol...dem for stay dere na make dem dey do one sim dey go..oppo, huawei, vivo and samsung will just take over and now that trump is asking dem to move their production factory to the US ehh..bye bye to them in local market
