Chinese manufacturer Xiaomi put the specifications of its latest premium intermediary to the test during practical evaluations in the Bonito region, in the Mato Grosso of the Sul. The device faced severe humidity conditions. The company’s proposal involves delivering a device capable of withstanding prolonged immersion without compromising the internal components during daily use. Testes confirmed the integrity of the system after direct contact with waterfalls. The model maintained normal operation even after an hour of floating in the water.

The device arrives on the market with the mission of raising the standard of the intermediate category. Ele combines an upgraded processor with rare endurance certifications. The highly reinforced physical structure comes with RAM memory options ranging between 8 GB and 12 GB to ensure fluidity.

Estrutura physics receives multiple certifications against water and dust

The device’s level of protection represents one of its main commercial attractions. The manufacturer included IP66, IP68, IP69 and IP69K certifications in the final project. Essa combination ensures defense against high pressure water jets and complete submersion. Independent body TÜV SÜD has validated the phone’s ability to remain under two meters of fresh water for an uninterrupted period of 24 hours. The rear part of the chassis uses ultra-resistant fiberglass. The product’s skeleton features an aluminum alloy developed to absorb severe impacts. The SGS certification certifies the equipment’s survival in drops of up to two and a half meters in height. The front panel receives the Corning Gorilla Glass Victus 2 layer of glass. Durante evaluations in outdoor environments, constant exposure to rain did not cause permanent damage. The sound system experienced temporary muffling, but audio clarity returned completely shortly after the moisture in the speakers naturally evaporated.

The industrial design of the product eliminates curved edges in the display area. The choice makes it easier to pick up. Consumers find the model available in light blue, black and brown in online stores. The robust construction allows the equipment to be transported without the immediate need for additional protective covers during extreme activities. The lack of concern about physical damage changes the dynamics of travel use.

Painel luminous ensures visibility under direct sunlight

The viewing area measures 6.83 inches and adopts AMOLED technology. The resolution reaches 2,772 x 1,280 pixels, a standard known in the market as 1.5K. The maximum brightness of 3,200 nits solves the chronic problem of screen reading on sunny days. The refresh rate operates at 120 Hz. Essa high frequency eliminates visual stuttering when scrolling web pages and playing electronic games. The display also natively supports HDR 10+, Dolby Vision and Vivid HDR formats.

Implementing these imaging technologies transforms color reproduction. Contrast gains depth when watching movies. The large screen size directly benefits the consumption of daily multimedia content by the most demanding users. The pixel density provides the sharpness needed for thorough evaluation of newly captured photographs. The glass finish minimizes reflections. Visual comfort remains stable even after long periods of continuous use.

Conjunto photographic uses high-resolution sensor and artificial intelligence

The rear camera module houses a 200-megapixel main sensor. The lens has an aperture of f/1.7 and a capture component measuring 1/1.4 inch. A secondary camera with an 8 megapixel ultra-wide lens complements the main system. The front of the phone houses a 32-megapixel sensor dedicated to self-portraits and video calls. The processing software delivers images with true-to-life tones and a slight bias towards cold colors.

The camera app provides a variety of tools for mobile photography enthusiasts. The interface includes specific features to optimize the final result of daily captures.

  • Modo Ultra HD for increased overall sharpness.
  • Quatro approximation levels without loss of visual quality.
  • Modo portrait with adjustable background blur.
  • Gravação of videos in 4K resolution.
  • Filtros nostalgic images generated by advanced algorithms.

Night performance presents a slight drop in texture definition. The behavior reflects a common limitation in the category. The complex post-processing system works quickly to recover lost details in the shadow areas of photographs. Native editing in the gallery uses artificial intelligence to brighten dark environments. The large sensor can absorb a considerable amount of light in challenging scenarios without generating excessive noise.

Processador focuses on energy efficiency and improved connectivity

The heart of the system is the Qualcomm Snapdragon 7s Gen 4 processor. The chip uses the four-nanometer manufacturing process. Modern architecture prioritizes energy savings when performing routine tasks and browsing social networks. Internal storage space offers 256 GB or 512 GB options. A cooling system with an enlarged vapor chamber prevents overheating. Thermal control ensures frame rate stability in moderate video games for hours on end.

Connectivity receives special attention with the inclusion of the proprietary Xiaomi TS1 Tuner chip. The component optimizes the reception of wireless network signals. The manufacturer reports an efficiency gain of up to 26% in Wi-Fi and Bluetooth connections compared to the previous generation. Satellite tracking also has greater accuracy in dense urban areas.

Autonomia battery exceeds a day of intense use

The power tank houses a cell with a total capacity of 6500 mAh. The volume represents a significant jump. Silicon-carbon technology allowed for an increase in energy density without making the phone excessively thick. Practical Testes with 4K video recording consumed only a fraction of the charge. The meter indicated 59% battery remaining at the end of a full day of evaluations in locations with no operator signal. The autonomy designed for a moderate usage profile easily exceeds the 24-hour mark.

Complete recharging occurs quickly thanks to the 100W socket adapter. The accessory injects enough energy to fill the battery in approximately 40 minutes when plugged in. The device acts as a portable power source. The 22.5W output allows for emergency charging of headphones and smart watches during long commutes. The battery maintains stable power supply even in environments with negative temperatures of up to -20ºC.

Interface updated and national market situation

The factory operating system is HyperOS 2, built on the basis of Android 15. The renewed interface speeds up opening applications. The HyperAI suite of tools introduces simultaneous translation functions and intelligent text suggestions to speed up typing. The microphone recognizes the user’s voice to generate automatic notes. The software also creates animated wallpapers from still photographs in your personal gallery with just a few taps on the screen.

The product does not have an official launch date in Brazilian stores. Independent Importadores sell the most powerful version on the internet. The model with 12 GB of memory and 512 GB of space starts at R$3,607 on the gray market. The original price abroad is around US$397.50. Direct conversion points to a cost of R$2,100 without the addition of local taxes and import fees. Purchasing outside official channels voids the right to authorized technical support and factory warranty in the country.
