Modified iPhone 13 Pro Max with USB Type-C port and 3.5mm jack is said to double the backup battery

An iPhone 13 Pro Max user named Yang Changshun modified the device so that users now refer to it as “iPhone 13 Pro Max Ultra”. The user has changed several components of the device and added some to maximize the performance of the iPhone 13 Pro Max. As a result, the battery life of the device has doubled, and the performance has reached a new record level.

A user from China posted a 37-minute video on his Weibo account of him modifying his iPhone 13 Pro Max. Let’s see what Yang Changshun changed in the iPhone 13 Pro Max to make it the iPhone 13 Pro Max Ultra.

Is this the most powerful iPhone ever?

The owner of the device added to his iPhone 13 Pro Max two built-in cooling fans with automatic speed control and a two-layer motherboard, which was filled with thermal paste. As a result, the performance of the device jumped by 1.54,000 in AnTuTu. The overall overall score of the original iPhone 13 Pro max it owned was 7,15,809, while the modified iPhone score reached 8,70,244.

The user then added a new battery, after which the battery life of the device doubled. The iPhone 13 series has already been applauded by viewers and critics for insane battery life, so think about how much double battery life would be on a modified iPhone 13 Pro Max?

And finally, the user added a USB-C interface and a 3.5mm headphone jack to the iPhone 13 Pro Max. These additions did not affect the operation of the lightning interface. The new additions worked great on a modified iPhone 13 Pro Max.

Earlier this year, iPhone X user Gernot Jobstl posted a video of himself modifying his iPhone X. The Lightining port on his iPhone X has been replaced with a USB-C port. Similarly, in 2021, engineering student Ken Pillionel showed off his own modified iPhone X smartphone with a USB-C port, which was subsequently sold in an online auction for $86,001 (roughly 64 lakh).
