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.

AirPods 2 Teardown: H1 Chip With Bluetooth 5.0, Same Batteries, and Water-Repellent Coating on Charging Case Board
The repair website also pried open the new wireless charging case, which continues to have a 398 mAh battery capacity, and said there is a new "water-repellent coating" on the circuit board. The teardown notes that the updated charging case "seems designed for increased durability, but not repairability."
Unsurprisingly, the new AirPods earned a zero for repairability, as iFixit says they remain "disappointingly disposable." AirPods are not designed to be serviced, as no hardware components can be accessed without damaging the earphones, and sealed-in batteries make the AirPods a consumable product.
Many of these details were already known, but the teardown still provides an interesting look at the internal differences compared to the first-generation AirPods. More photos and tech specs are available over on iFixit's website.
