Modified iPhone 13 Pro Max "Ultra" has twice the battery life, a USB-C port and more
The iPhone 13 Pro Max is the first iPhone with a battery capacity that measures over 4,000mAh. The phone has insane battery life thanks to the 4352mAh battery powering the device. In a battery test we ran pitting the iPhone 13 Pro Max against the Galaxy S22 Ultra, the Galaxy S21 Ultra, the Pixel 6 Pro, and the OnePlus 10 Pro, the iPhone was able to browse at 120Hz for nearly 19 hours before the battery went belly up.
Even more amazing, a gentleman by the name of Yang Changshun modified his iPhone 13 Pro Max and in the process, he doubled the battery life. According to MySmartPrice, to keep things cool under the hood, Yang added two built-in automatic speed adjustment cooling fans and employed a double-layer motherboard which he filled with thermal paste.
The phone's Lightning port was replaced with a USB-C port and a 3.5mm earphone jack was added to the phone. With all of the improvements, the device was given a revised name: The iPhone 13 Pro Max Ultra. And the modifications helped the handset hike its AnTuTu benchmark score by 21.5% to 870,244.

You might recall that last year an engineering student by the name of Ken Pillolel replaced the Lightning port on his iPhone X with a USB-C port. He was able to keep the same capabilities that the original port offered including data transfer and fast charging. The phone was sold in an online auction fetching a princely sum of $86,001.
It would be interesting to see what the so-called "iPhone 13 Pro Max Ultra" would command at auction. If you're thinking about doing something similar, Apple will void the warranty on your phone.
