Also, like previous iPhones, both phones do not have a headphone jack, and initially came with wired EarPods with a Lightning connector, although Apple no longer includes these with any device.
As with the iPhone 11 Pro, XR, XS, and X, the display has a notch at the top for the TrueDepth camera system and the speaker.
The phone also has an automatic night mode allowing the camera to take brighter pictures with reduced noise in low-light environments.
Apple has also announced a new Deep Fusion feature that takes advantage of AI and machine learning for image processing and was released via iOS 13.2 software update on October 29, 2019.
[27][30] Reviews generally praised the phone's performance, battery life, and cameras, while criticizing the display as passable, but aging quickly.
According to Counterpoint Research's Market Pulse, it was the second best-selling and the most popular model globally for 2019, in less than four months of launch.
Removing these items is claimed to reduce e-waste and permit a smaller iPhone box, allowing more devices to be transported simultaneously to decrease carbon footprint.
