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.

2019 iPhone Lineup Rumored to Include Two New OLED Models With Triple Lens Cameras
Citing reliable sources in the Chinese supply chain, the report claims that the two new iPhone models would come with 6.1-inch and 6.5-inch OLED displays and the previously heavily rumored triple-lens camera system.
The report goes on to suggest the two new models will have a thicker body to compensate for the larger camera module, so the 6.1-inch model will be around 0.15mm thicker than the existing iPhone XS, while the camera bump will see a 0.5mm reduction in protrusion.
Likewise, the body of the 6.5-inch model will supposedly be 0.4mm thicker with a camera bump reduced by 0.25mm, which equates to an overall 0.2mm thickness increase over the current iPhone XS Max.
Mac Otakara claims the two new models will come with a USB-C to Lightning cable and an 18 Watt USB-C power adapter, with an ability for the rear of the phone to wirelessly charge Qi-compatible devices like Apple Watch and AirPods 2 "likely."
In general, the rumor mill narrative suggests triple lens camera systems are a given this year, but most other leaks – from OnLeaks in particular – have implied that the three-lens camera won't be exclusive to any one iPhone, and certainly don't suggest it will be a unique feature of additional models in Apple's lineup.
Given the leftfield claims, today's report should be taken with a grain of salt, although Mac Otakara has provided accurate information on unreleased iPhones in the past, so it's possible there's something to it.
