An alleged iPhone 13 Pro Max replica features on a prominent tech YouTube channel

Apple is currently projected to launch a range of iPhones that correspond to those of the 12 series in 2021. Therefore, the top-end variant should be called the 13 Pro Max. It is said to look much like its forebear, albeit with certain, potentially significant tweaks such as a change of notch for the first time in several generations.

Now, the well-known YouTuber Lewis Hilsenteger has showcased what is claimed as a highly accurate, albeit non-functional, model of the 13 Pro Max that might completely spoil its launch later this year. Admittedly, it looks convincing enough, with a flat metallic frame as in the 12 Pro Max that accomodates ports (Lightning included) and buttons in approximately the same locations.

Then again, the replica in this new Unbox Therapy clip may confirm some important iPhone design upgrades for 2021. It does indeed have the smaller notch hinted at in earlier leaks, with an earpiece that has migrated to meet the device's top edge to fit.

Hilsenteger measured this "new notch" at 26.31 millimeters (mm) in length, whereas that of a 12 Pro Max came in at 34.62mm. The other biggest difference between that phone and the alleged dummy of its successor are the rear cameras. 

They are larger in the "iPhone 13 Pro Max" (measured at 16.99mm high as opposed to 14.1mm in the 12 Pro Max), yet have smaller internal borders around all 3 lenses, thus possibly hinting at larger sensors in the upcoming flagship.

The iPhone 13 series is also currently tipped to upgrade to the 120Hz ProMotion displays that never made it to the 12s, as well as inaugural 1TB storage options.
