Realme 320W fast charging technology explained: breaking industry records

After the 240W super flash charging technology brought mobile phone charging into the 9-minute era, Realme once again brought the latest breakthrough technology to refresh the ceiling in this field.

On August 14, Realme Mobile launched the world’s first flash charging black technology – 320W ultra-fast charging, marking another revolutionary leap in mobile phone flash charging speed and Chinese technology once again leading the world.

Realme 320W super-fast charging has achieved unprecedented breakthroughs in power, safety and efficiency. It not only pushes the industry’s flash charging technology to a new height, but also brings users a brand new flash charging experience.

320W ultra-fast charging, a miracle experience in 4 minutes and 30 seconds

The 320W super-fast charging technology has pushed the charging speed to a new level. It only takes 4 and a half minutes to charge a 4420mAh mobile phone battery to 100%, which has further improved the charging efficiency compared to the previous 240W flash charging technology.

Behind this achievement is actually the trade-off between “high power, high safety and miniaturization”. Zhenmi, which has been exploring the field of flash charging technology for a long time, has not only brought about a breakthrough in power, but also achieved a balance among the three through technological innovation.

The world’s first foldable smartphone battery breaks the power limit again

In order to achieve 320W high-power charging, Realme brings the world’s first folding battery for smartphones, the “10,000 yuan folding screen” among batteries.

Realme cut a battery into four cells and used flexible circuit boards and high-density stacking technology to successfully fold the four cells and put them into the phone. Each cell uses an advanced stacking process with a thickness of only 2.9mm, but the capacity is 10% higher than the traditional design. While increasing the battery capacity, it also ensures the stability and safety of the battery.

In addition to the technological breakthrough of the battery itself, this 320W super-fast charging has also achieved a comprehensive innovation in the charging ecosystem. From the design of the charger, charging protocol, charging software algorithm to the battery pack cell, down to the performance guarantee of each component, Realme has achieved an industry-leading level.

Realme launches the “power transmission through air” technology for the first time, further upgrading charging safety

In terms of charging safety, which is of most concern to users, Realme has also made great efforts. As a pioneer in the field of flash charging, Realme has commercialized a number of safety protection measures including adapters, interfaces, battery overload protection, battery fuse protection, etc. On top of this, the 320W flash charging technology based on the UFCS fusion fast charging standard supports more precise voltage and current step adjustment, which improves the safety of the charging process.

In addition, Realme launched the first “wireless power transmission” technology, namely high-power density magnetic coupling DCX step-down technology, which can ensure that high voltage is isolated from the battery when serious faults such as circuit breakdown occur, thereby avoiding the safety risk of battery overvoltage charging.

The biggest difficulty of this technology lies in the miniaturization of the module. Through technological research and development, Realme has compressed it to a thickness of only 3mm. More than ten patented technologies allow the fingertip-sized module to achieve 40V to 20V voltage conversion while maintaining excellent conversion efficiency and thermal management, enabling the 320W super-fast charging to achieve a power efficiency of about 98%, while ensuring safety while achieving high power.

Dual-port output and dual-fast charging, high power and portability

In terms of portability and compatibility, Realme has also made a comprehensive innovation. The 320W ultra-fast charging head has a power density of 3.3W/cubic centimeter. While being compact and portable, it also supports two Type-C outputs and is compatible with mainstream fast charging protocols on the market, including UFCS (up to 320W), SuperVOOC, PD, PPS and other protocols. It not only meets users’ needs for high-power flash charging, but also supports charging two devices at the same time, taking into account portability.

Five major black technologies are launched simultaneously to promote the comprehensive upgrade of user experience

In addition to the industry-leading flash charging technology, Realme also brings five new black technologies in vision, hearing and touch. The industry’s first AI game super-resolution technology that uses the end-side AI model to improve the resolution in real time, bringing a clearer visual experience.

The holographic audio technology that can adjust the sound positioning will not disturb the game process by the incoming call reminder, bringing a more immersive gaming experience. The world’s first anti-reflective display for smartphones significantly reduces the screen reflectivity, and has a clear visual effect even in low-light environments.

The industry’s first solid-state button that supports sliding and pressing sensing, which allows you to slide and zoom and press the shutter while taking photos, bringing the same silky touch as a camera. There is also AI image-generated video, which can convert a single image into a dynamic 25-frame video, turning a still moment into a vibrant story. The release of these technologies further demonstrates the strength and determination of Realme in technological innovation, and promotes the overall level of innovation in the industry.

As a leader in flash charging technology, Realme has always been committed to improving user experience through technological innovation. The launch of the 320W ultra-fast charging technology not only demonstrates Realme’s deep accumulation in the field of flash charging technology, but also sets a new benchmark in the smartphone market.

Realme combines technology with consumer insights to create high-performance products for users, providing young people around the world with outstanding technology that exceeds expectations, and allowing Chinese technology to once again lead the world.
