For several years, Chinese brands have been waging an open war in order to offer the fastest possible recharge. And in this little game, Realme may well have taken a step ahead. The manufacturer, owned by the Chinese consortium BBK Electronics, is preparing to launch its Realme GT Neo 5, a smartphone that will benefit from a 240 W recharge.
The GT Neo 3 was already available in a version capable of supporting 150 W. It is therefore an important development for the brand, which even exceeds the previous record held by the Xiaomi Redmi Note 12 Discovery Edition, which offers a charge at 210W.
The promise is impressive: being able to fully charge a 4500 mAh battery in 9 minutes. Suffice to say that it will only take a few moments to find 20% or 30% of the battery if necessary. A feat that relies in particular on the SuperVOOC technology developed by Oppo.
This new 240 W protocol is compatible with other standards such as Power Delivery (PD up to 65 W), Quick Charging (QC) and VOOC.
Thanks to batteries divided into several blocks, it is possible to reduce the voltage and increase the amperage. The charger should therefore send an electrical voltage of 20 V at an intensity of 12 A. The smartphone will then convert this electrical current into 10 V 24 A to charge each of the parts of the battery.
The manufacturers also surround the accumulators with graphene in order to increase conductivity, as we mentioned in our test of the HyperCharge technology of the Xiaomi 11T Pro.
To cope with such power, Realme had to modify an existing cable model to support higher amperage (12 A). The charging block, which uses a USB Type-C output, is 5% larger than the 150W one used previously.
Control the heating
As with each new advance, the question of heating arises. Realme specifies that its GT Neo 5 will be equipped with thirteen sensors responsible for analyzing the temperature of the smartphone, and promises excellent heat dissipation. This will have to be checked in the lab, since we have nevertheless observed significant heating on the previous models.
The manufacturer also promises that the battery will be able to withstand 1600 full charge cycles while retaining 80% of its capacity. Which is reassuring on paper.
Ultra-fast charging will obviously not be the only advantage of the GT Neo 5. Scheduled for the month of February, it should in particular be equipped with the very good Snapdragon 8+ Gen 1, but also with a 50 Mpx Sony IMX890 main sensor, still unknown, but promising. A standard version, compatible with charging at 150 W “only”, is also planned.
We can therefore expect a move upmarket… and an increase in prices. Especially since Realme has already attempted a few forays into the high end before.
