Content creator Arun Maini, better known as Mrwhosetheboss, has achieved an extraordinary feat by building the world’s largest iPhone 15 Pro Max replica. This impressive creation, officially certified by the Guinness World Records, stands over two meters tall, making it a giant among smartphones. While Apple did not manufacture this device, its scale and functionality have drawn significant attention worldwide. Let’s take a closer look at what makes this unique build so remarkable.
The design process: Scaling up to giant proportions
Mrwhosetheboss teamed up with Matthew Perks, another content creator renowned for his DIY projects under the name DIYPerks, to bring this ambitious project to life. The pair set out to create a fully functional iPhone 15 Pro Max replica, using cutting-edge technology and innovative design techniques. At the heart of the build is an 88-inch LG OLED TV, which serves as the device’s screen. This screen alone towers over most users, necessitating a custom-built stand to support the colossal replica.
The design was meticulously planned to replicate the actual iPhone 15 Pro Max. However, scaling a smartphone to this size required more than just enlarging its physical dimensions—it also demanded an engineering overhaul to ensure the device was operational. One of the highlights is the integration of two powerful cameras: a Canon EOS R5, capable of 25x optical zoom, and a Sony RX10 Mark IV, installed behind the device in one of three camera slots. These additions allow the oversized iPhone to capture high-quality images, enhancing its functionality as a working smartphone replica.
A fully functional giant smartphone
One of the most fascinating aspects of this record-breaking replica is its functionality. Despite its size, the device is not just for show—it’s a fully operational smartphone. Social media platforms like YouTube, Instagram, and TikTok run smoothly on the 88-inch screen. The display itself is capable of rendering content in up to 8K resolution at a remarkable 230 frames per second (FPS), making it a powerhouse for multimedia applications.

To support its immense size, the device also comes equipped with eight speakers, each rated at 50 watts, ensuring that sound quality matches the visual experience. For low-light conditions, a built-in 400-watt torch provides ample illumination, acting as a powerful overhead light.
In one of the video showcases, Mrwhosetheboss and his team tested various functionalities, including watching videos, playing games, and even writing an email to Apple CEO Tim Cook. They even managed to make a contactless payment at an ice cream shop using the oversized replica. When the device’s “battery” runs low, they simply connect it to power with a custom USB-C Pro Max cable, cleverly disguised as a kettle cord hidden within the outer wiring.
Under the hood: Power and performance
The inner workings of the largest iPhone 15 Pro Max replica are equally as impressive as its exterior. It is powered by a robust Intel Core i9 24-core processor, which provides the computational power required to handle the complex tasks assigned to the device. The replica boasts a staggering 128 GB of RAM and a total of four terabytes of memory, split into two partitions: two terabytes for Android and two terabytes for Windows.

This dual operating system setup allows the device to function as both an Android and Windows machine, offering greater flexibility than Apple’s native iOS. It provides a platform for supersized apps and settings that would otherwise be restricted on a traditional Apple device. For instance, playing games like Angry Birds on the massive screen becomes a surreal experience, magnified in both size and detail.
The Guinness World Record certification
In addition to its technological prowess, the iPhone 15 Pro Max replica has also earned its place in the record books. Mrwhosetheboss was officially presented with a Guinness World Record certificate for creating the largest smartphone replica in the world. The achievement marked a personal milestone for the content creator, fulfilling a long-standing dream.

This record-setting replica is a testament to the ingenuity of the creators and their dedication to pushing the boundaries of what is possible in DIY projects. For the content creators, it was not just about the physical size of the device but also about demonstrating how functional and interactive such a creation could be.
The price of building the largest iPhone
While the feat of creating the largest iPhone 15 Pro Max replica is impressive, it did not come cheap. The total cost of the components used to bring this project to life amounted to a staggering $70,630. This figure includes the price of the 88-inch OLED screen, high-end cameras, processors, and other technical components.

For those looking to replicate this project themselves, the cost alone might be a deterrent, not to mention the advanced technical skills required. However, for Mrwhosetheboss and his team, the investment was worthwhile, culminating in a one-of-a-kind project that showcases both innovation and creativity.
