Notable improvements over the previous devices include the triple-lens rear camera system and the A13 Bionic chip.

Details regarding the iPhone 11 Pro line were leaked widely starting several months before the official release, with complete specifications, renderings, and real-life images of the phone being publicized.

Substantial advancements in the camera and the continuation of the 'notch' design featured since the iPhone X were correctly predicted in leaks.

[9][10][11] Some leaks, however, were inaccurate; the inclusion of bilateral charging was widely anticipated and publicized, but was not part of the phone's design.

There is also a new rear camera design with three lenses and a flash in a larger, square-shaped bump, which is the most visible difference compared to the iPhone XS.

Continuing the trend set starting with the iPhone 7, neither phone includes a headphone jack, but came with wired EarPods with a Lightning connector prior to Apple's decision to halt inclusion of them in October 2020, citing environmental impact.

Both models feature a Super Retina XDR Display with a 2,000,000:1 contrast ratio and a notch at the top for the TrueDepth camera system and speaker.

iPhone 11 Pro also has an automatic Night Mode allowing the camera to take brighter pictures with reduced noise in low light environments.

There is also a redesigned camera app that adds new features such as a scroll wheel for choosing between the different lenses and long-pressing the shutter button to take a video.

Apple has also announced a new Deep Fusion feature which will take advantage of AI and machine learning for image processing.

[28] However, Apple limits the full range of zoom (0.5× -6×) while shooting in 4K @ 60fps to either 0.5× – 1.5×, 1×, to 2× depending which lens is selected upon recording.

Similar to previous iPhone models, the TrueDepth system is also used for Face ID and Animoji.

[34][35] The device received an overall score of 117 from DXOMARK, ranking it as the second-best smartphone camera on the site tied with the Samsung Galaxy Note 10+.
