JAKARTA - Smartphone endurance tests usually stop at the level of falling from a table or being splashed with water. But this time it's a different story. Ulefone really "gaspol" shows the durability of Ulefone RugKing 5 Pro in an extreme way: make it a tool to break Durian - a fruit known for its super hard skin and sharp thorns.

This action is not just a gimmick. In a demonstration video released by the company, the device is used to hit various hard objects, ranging from ordinary fruit to whole durian. As a result, after several blows, the durian finally opens, while the device still works normally without significant damage.

This testing method clearly goes beyond conventional durability test standards, which generally only include simulations of everyday use such as falling from a certain height or scratch tests using objects such as keys and coins.

Professional Endurance Extreme Test

In the demonstration, Ulefone did not only rely on durian as a test object. The device was also used to destroy other fruits such as pineapple, which has a hard and fibrous texture. However, durian remains the main indicator due to its high level of hardness.

The company insists that the RugKing 5 Pro is specifically designed for use in extreme environments, such as construction projects, outdoor activities, and heavy field work conditions.

In terms of construction, this device uses high-density polycarbonate material combined with a reinforced metal frame. This combination is claimed to provide maximum protection against hard impacts.

In terms of certification, this device has bagged the IP68 and IP69K standards, which means it is resistant to dust, high-pressure water, and can survive in water immersion conditions for up to 30 minutes.

In addition, the RugKing 5 Pro also meets the MIL-STD-810H military standard, which tests the durability of the device against various extreme conditions such as high temperatures, humidity, and vibration.

Support Specifications

Not only superior in physical endurance, the RugKing 5 Pro is also equipped with specifications that support activities on the field. One of its main features is a 20,000mAh capacity battery, which is designed for long-term use without having to charge often.

This device is also equipped with a camping lamp with a brightness level of up to 976 lumens, making it a multifunctional tool for outdoor or emergency needs.

In terms of the screen, this smartphone carries a 6.78-inch panel with FHD+ resolution, providing a visual experience that is still comfortable even when used outdoors. The operating system is running Android 16, ensuring compatibility with the latest applications.

Ulefone says the device is available through various sales channels, including global e-commerce platforms such as Amazon and their official store.

More than just a Smartphone

Ulefone's move to use durian as a test tool is not only to attract attention, but also as a symbol of product positioning: a device that is able to survive even in the harshest conditions.

In the midst of a smartphone market that is increasingly focused on thin design and aesthetics, the RugKing 5 Pro comes as an antithesis - prioritizing function, durability, and reliability.

For some users, this may seem excessive. But for field workers or extreme adventurers, this kind of ability is not a gimmick - but a necessity.
