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 7 Plus Likely to Have Dual-Lens Camera Based on LinX Technology
The rumored iPhone 7 Plus model with a dual-lens camera system would take advantage of imaging algorithms that Apple acquired through its purchase of Israeli camera technology company LinX Imaging last year.
LinX technology offers several improvements the iPhone 7 Plus could benefit from, including multiple sensors for a smaller size, possibly eliminating the need for a protruding camera lens. The lenses would also have better sensitivity to light and greatly improved image quality in low light.
Specifically, Kuo cites the LinX Imaging algorithm for its unique ability to achieve high-end dual-camera applications such as optical zoom simulation while sidestepping the traditional bottlenecks associated with compact camera module (CCM) assembly.
To that end, Kuo expects a 2-3x optical zoom function to feature in Apple's iPhone 7 Plus. However, owing to supply chain constraints on dual-camera modules, the KGI analyst expects the larger handset to come in single-camera and dual-camera versions.
Apple is well known for headlining improvements to the camera technology in its iPhones and showcasing their photography capabilities as a market-leading feature.
Even so, major improvements to camera technology have typically come in "S" release years, therefore it remains to be seen whether Apple chooses to include such improvements in this or the next generation of its flagship devices.
