Design & Build
The Armor X31 Pro is built like a tank, with a design focused on endurance and functionality. It boasts IP68/IP69K water and dust resistance, along with MIL-STD-810H military certification. This means it can withstand extreme temperatures, high humidity, shocks, and submersion in water. The reinforced corners and textured back panel offer excellent grip and added protection against drops.
While the phone’s rugged design makes it bulkier than traditional smartphones, it’s a trade-off that many outdoor enthusiasts are willing to accept. The physical buttons, including a customizable side key, are well-placed and easy to use even when wearing gloves. Overall, the Armor X31 Pro’s design emphasizes practicality and durability over aesthetics.
Display & Performance
The Ulefone Armor X31 Pro features a 6.56-inch IPS display with a resolution of 720 x 1612 pixels and a 120Hz refresh rate.

The high refresh rate ensures smooth scrolling and responsive touch inputs, which is a significant advantage for a rugged phone.
The display is protected by Corning Gorilla Glass 5 and is designed to be readable under direct sunlight with 800 nits brightness, making it suitable for outdoor use. However, the lower resolution may be noticeable when watching videos or viewing detailed images.
Under the hood, the Armor X31 Pro is powered by the MediaTek Dimensity 6300 chipset, paired with 8GB of RAM and 256GB of internal storage. This combination provides ample power for everyday tasks, multitasking, and even moderate gaming. The Dimensity 6300 is a mid-range chipset, offering efficient performance and decent graphics capabilities.
The phone runs on Android 14 with a stock interface, ensuring a clean and intuitive user experience. The absence of bloatware is a welcome feature, allowing users to make the most of the available resources.
Camera
The Armor X31 Pro is equipped with a triple-camera setup on the rear, comprising a 64MP primary sensor, a 25MP secondary night vision sensor, and a 2MP macro lens. The main camera captures detailed and vibrant images in good lighting conditions, while the secondary sensor enhances depth and color accuracy. The macro lens, while functional, is more of a supplementary feature and delivers average results.
On the front, there’s a 16MP selfie camera that performs well for video calls and casual selfies. The camera software includes various modes and features, such as night mode and portrait mode, to enhance the photography experience. While the overall camera performance is not on par with flagship devices, it’s commendable for a rugged phone.
Battery & More
One of the standout features of the Armor X31 Pro is its massive 6050mAh battery. This ensures extended usage time, making it an ideal companion for outdoor adventures or work in remote locations. The phone easily lasts more than a day of heavy use and can stretch to two days with moderate usage.
The device supports fast charging, allowing you to quickly replenish the battery when needed. However, wireless charging is not mentioned, which might be a drawback for some users.
The MIL-STD-810H certification and IP68/IP69K ratings ensure the phone can survive harsh environments, making it perfect for outdoor professionals and adventurers. Moreover, the Armor X31 Pro supports 5G connectivity, dual SIM functionality, and a range of sensors, including a barometer and compass, to aid outdoor navigation.
Conclusion
The Ulefone Armor X31 Pro is a solid choice for users who prioritize durability and long battery life over sleek design and high-end specifications. Its rugged build, ample performance, and practical features make it an excellent companion for outdoor enthusiasts, field workers, and anyone needing a phone that can withstand harsh conditions. While it may not appeal to those looking for a premium display or flagship-level camera performance, it delivers exceptional value in its category.
For its target audience, the Armor X31 Pro strikes a balance between ruggedness and functionality, making it a dependable tool in the toughest environments.
