During the MWC 2023 exhibition, Redmi, which is a sub-brand of Xiaomi, introduced the fastest charging for smartphones with a power of 300 watts. According to the official demo on the Redmi Note 12 Discovery Edition, this charge is able to fully charge a 4,100Wh battery in just 5 minutes. At the same time, the battery replenishes 10% in 43 seconds, and 50% in 2 minutes.
According to official figures, the peak charging power of the smartphone is slightly lower than the maximum – 290 watts. At the same time, the full potential (when the threshold of 280 W is exceeded) is revealed only in the first 2 minutes of charging.
Redmi says that it has specially created its own architecture for this technology, its efficiency reaches 98%. Unlike previous developments, the components in the new product are located in a decentralized manner, which avoids concentrated heat generation and thereby increases the duration of a powerful charge. At the same time, “more than 50 means of protection” are provided in charging, apparently from overheating, short circuits and other contingencies.
At the moment, 300-watt charging has been demonstrated only in test mode – the likelihood of its appearance in mass devices has not been announced.
