The iPhone X doesn't have a battery percentage indicator like the other iPhones, is there any way to see it?
Indeed, because of the "notch" there is less room at the top of the iPhone X screen to show information. Battery percentage was a casualty of this, along with the alarm clock, Bluetooth and a few other symbols. However, you can still view these in your Control Center. Just drag down from the top right corner to see your battery percentage.
