It’s worth highlighting that the device allows adjustment of the screen’s refresh rate to offer a choice from 60Hz to 120Hz, to provide remarkably smooth transitions and interactions, making every swipe, scroll, and gaming experience more fluid and responsive. You should know that a higher refresh will affect the device’s battery life, so if that’s your priority, leave it at 60Hz.

The color reproduction on the Power Armor T18 Ultra display is vibrant, rendering images and videos in a captivating manner. The IPS panel offers good color accuracy and impressive contrast, making content come to life with a natural and pleasing vibrancy. Moreover, the display settings allow customization of the visual experience, from adjusting the brightness, and color temperature, and applying night mode, catering to various user preferences.

The screen’s sensitivity is further demonstrated by its ability to handle up to 10 simultaneous touches, unlike some newer iPhone models that support only five. Moreover, the device offers a touch sampling rate that impressively surpasses expectations, delivering optimal responsiveness. The device’s exceptional Corning Gorilla Glass 5 adds to its durability and allows it to withstand drops from heights of up to 1.8 meters. These features make it one of the most secure and rugged smartphones available.

Playing Content

Playing the content on YouTube, was very smooth. You can play videos at a maximum of 1080p at 60 FPS without any problems or lag, And this is the highest quality you can get. My major issue however is the lack of Widevine L1 certification which restricts the video resolution on most streaming services to a mere 480p. While this does not become an immediate deal breaker, if you like watching your content on your smartphone, this might be an issue. This level may be difficult to find in many Chinese smartphones without exaggeration.

Camera Capabilities

At the heart of these remarkable devices of Ulefone Power Armor 18T Ultra and 18T Ultra is its triple-lens camera system, led by a cutting-edge 108MP Samsung HM2 main camera. The HM2 is a very popular choice for rugged designs now, as it’s a massive 108MP 1/1,52” sensor that includes Samsung’s ISOCELL Plus and Smart-ISO technology. The inclusion of a 108MP sensor, a feature typically reserved for mid-range and high-end regular smartphones, places both phones in a league of its own. This sensor’s super high original resolution supports 9-in-1 pixel binning, a technology that captures an abundance of light while maintaining commendable noise control.

The result? Stunningly vivid colors with a remarkable contrast that brings your photos to life. The samples captured on this camera not only meet but exceed expectations, showcasing the device’s prowess in delivering exceptional photography experiences, even in rugged environments.

Beyond the powerful main camera, both phones introduce two more remarkable lenses. The first is the super microscope lens with 60X zoom. What sets this lens apart is its extraordinary close focus, eliminating the need for intricate adjustments to find the perfect focus. The fixed focus allows users to place the device directly on the subject’s surface, offering unparalleled convenience. During shooting, a ring of fill light around the lens illuminates the subject, ensuring clear and detailed shots, even in challenging lighting conditions.

The second addition to Ulefone Power Armor 18T Ultra its camera setup is the thermal camera, incorporating a thermal imaging camera and a FLIR Lepton 3.5 Sensor with a resolution of 150 x 120. The thermal sensor adds a unique dimension to the 18T Ultra’s capabilities through the ability to explore thermal imaging, making the device invaluable in various applications.

But, Ulefone Power Armor 18 Ultra has the temperature measurement, which actually works the same as a regular non-contact thermometer. In the back module between the cameras there is a sensor that measures the temperature. It can measure body temperatures from 35 to 42°C (accuracy ±0.2°C), object temperatures from -20 to 80°C (accuracy ±0.5°C) and ambient temperatures from -20 at 80°C. To use, hold the device up to aim at the target and tap “Measure” on the screen. The accuracy is quite good, comparable to a regular non-contact thermometer. Historical readings can be viewed at any time.

While the Power Armor 18T can record up to 4K 30FPS, although all video is restricted to 30fps, sadly. Also, it lacks any on-sensor image stabilization, resulting in slight jitters in the output video that would need post-processing to clean up for any professional use.

The 32MP Samsung S5KGD1 selfie camera on the front of the phone is also passable, but again, nothing outstanding. The images felt somewhat dull and lifeless, but this is acceptable for a rugged phone. Videos from the selfie camera are restricted to 1080p@30FPS.

It’s clear that Ulefone didn’t prioritize the best camera performance for this device. That’s not to say it’s bad—it’s just best described as utilitarian. Between the main camera, an endoscope, a microscope, and thermal imaging, the Power Armor 18T can handle any kind of surveying needed. It might not be best suited to your Instagram holiday snaps, though.

Performance and Gaming

The Ulefone Power Armor 18T Ultra sets itself apart by being one of the pioneering smartphones to adopt the advanced MediaTek Dimensity 7050 5G chipset.
