Night mode is an automatic setting which takes advantage of the new wide-angle camera that's in the iPhone 11 and 11 Pro models. It's equipped with a larger sensor that is able to let in more light, allowing for brighter photos when the light is low.
iPhone 6 and iPhone 6 Plus Get Cracked in First Drop Test
The iPhone 6 did well when dropped on the side and back, but unsurprisingly suffered when dropped on its face. The 6 Plus, on the other hand, cracked when it landed on the side. However, it sustained little further damage when falling on its face.
Based on this one test, both phones may have performed worse than the iPhone 5 design which was described as "very durable" and survived similar drops in a previous drop tests. Without standardized testing, it's hard to draw definitive conclusions.
