Xiaomi’s impressive 200W fast charging might actually become reality

Do you remember Xiaomi’s impressive charge “flex” back from the announcement of the Mi 11 line in May? Xiaomi showcased a Mi 11 Pro charge at a reported 200W and goes from 0 to 100% in just 15 minutes. We are not getting into the debate about whether this kind of charging speed is useful or past the point of declining returns. Instead, we will focus on the fact that it was undoubtedly a major PR stunt, with Xiaomi even claiming to have broken a few world records in the process. Xiaomi called the technology Xiaomi HyperCharge, and it did not take long before some further details about it all also came to light, as did the fact that the Mi 11 Pro used in the demo had a custom 4,000 mAh battery instead of its typical 5,000 mAh and the 800 charge cycles, the battery lost 20% of its capacity. Which may sound bad, but is actually better than the official China requirements of 60% retained battery capacity after 400 charges. But we differ.

The general consensus after the dust was that the 200W charging technology for some reason did not come to actual end-user devices soon. Well, it turns out that it does not tell the whole story, and charging at 200 W may be closer than you think.

It turns out that the company behind the 200 W charging technology is actually called NuVolta Technologies – a major player in charging design and silicon space. According to a new report, the company recently launched a second generation of its fast charging chip for the pump. The same behind the Xiaomi HyperCharge. NuVolta NU2205 is apparently the single fastest charging chip with the highest power in the industry capable of reaching 100W. It is also the only Chinese chip to support dual-cell 4: 2 fast charging architecture, which is how the commutative total of 200W is achieved across a segmented battery.

It is clear that NU2205 is currently a unique offering in the market. NuVolta Technologies is particularly proud to have managed to break the monopoly of foreign companies in the dual-cell fast-charging area. Best of all, this may be good news for more than just Xiaomi and its devices. Although Xiaomi will still probably be the first to actually place the technology in a production phone, if we read the room correctly, it sounds like the NU2205 could also be offered widely and sold to other manufacturers. Exciting times ahead for sure!
