A new leak suggests that the iPhone 13 will come with Always-on Display (AoD) functionality, upgraded materials, and a new astrophotography mode.
Max's source also suggests that the iPhone 13 Pro will ship with an improved matte black finish. To quote LeaksApplePro, "The matte back is getting refined. So in the 2021 iPhones, I'm sure Max is referring to the Pro models, they'll have a slightly more grippy texturized back. He says they'll be slightly more comfortable and he assumes it'll like a soft matte, like on the Pixel series." A high-refresh-rate (120Hz) LTPO display will also likely make its debut on the iPhone 13 Pro.
The video also states that the iPhone 13 body will remain identical to its predecessor, with a few centimetres of thickness adjust here and there. Therefore, we can expect to see the same triple-camera setup on the iPhone 13 Pro and dual-camera array on the non-Pro variant. We have heard multiple times in the past that the iPhone 13 series is expected to come with an upgraded ultra-wide-angle lens.
The video also speculates that the new iPhones will come with a dedicated astrophotography mode, similar to what we've seen on the Google Pixel series.
