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.

IBM's Lawsuit Against Papermaster Over 'Racetrack' Memory? [Update]
The memory technology called "racetrack" memory was previously detailed in a Times Online article:
Scientists at IBM say they have developed a new type of digital storage which would enable a device such as an MP3 player to store about half a million songs - or 3,500 films - and cost far less to produce.The new technology is said to require much less power and could run on a single battery charge for "weeks at a time." The technology, however, was described as "exploratory" just earlier this year and end-user products weren't expected for 10 years.
It's unclear how involved Papermaster was in the development of this technology, and how serious a concern this is for IBM. Papermaster was IBM's vice president of microprocessor technology development prior to his departure.
Update: ZDNet reports the connection between Papermaster and "racetrack" memory is very tenuous at best.
