OPPO has revealed that it has developed a customized 15C high-rate battery, which suggests that 300W fast charging is on its way. This announcement comes a month after Redmi unveiled a modified version of the Note 12 Pro+ with 300W fast charging that could be fully charged in just five minutes. Recent reports have revealed that Redmi’s 300W charging technology will be launched this year, and a mass-produced model may be released in the second half of the year. OPPO too could be planning to launch its 300W charging technology this year.
According to a Digital Chat Station, the Oga Group (OPPO and OnePlus brands are part of this group) has customized 2220/2230mAh 15C system high-rate batteries, with an equivalent capacity of around 4600mAh. This battery is expected to be prepared for 300W rapid charging. At present, the Oga Group is currently testing the charging technology.
However, achieving high-power fast charging of 300W is not as simple as using a high-rate battery. Optimization and innovation of the entire charging link, including charging chargers, mobile terminals, and charging architectures, are required.
In addition, the 300W charging chip also needs to be built with the latest generation of GaN (gallium nitride) technology, which helps to further reduce the volume. If the charging chip isn’t small enough, then the volume of the charging head and the mobile phone won’t be controllable.
While the 300W fast charging sounds promising, it’s essential to compare it with the more mature 100W fast charging, which often comes with a 5000mAh or above-sized battery. The 300W battery capacity is still smaller, which could lead to a relatively lower battery life. Nevertheless, the charging time is greatly reduced, which could be a matter of trade-offs for some users.
