The structure of iPhone X is similar to that of how iPhone was built in the past; the display hinges at the top and is connected to the board at the right, so when it opened, it hinges to the right.

When the iPhone X was formed turned down, first thing we noticed was that it supports dual batteries. Apple must have split the battery in two packs to fit other components around two small batteries.
The motherboard of iPhone X was taken out which was very small.
