The Charging wars are escalating again and Xiaomi is firing it with 200W this time around. In May, Xiaomi posted on Twitter to flex its latest fast wired and wireless charging developments.
Xiaomi used a custom built Mi 11Pro with a 4,000mAh battery instead of the 5,000mAh battery with wired charging at 200W and wireless charging at 120W. The results were more than impressive with the wired charging solution getting the device to 100% in just 8 minutes whereas the wireless charging needed only 15 minutes.
The 200W charger only took 44 seconds to get the battery from 0 to 10% and 3 minutes to get the battery from 0 to 50%, followed by a 100% charge in just 8 minutes.
In terms of wireless charging, the 120W charger took 60 seconds to get the charge from 0 to 10% and 7 minutes to get the battery from 0 to 50%, followed by a 100% charge in just 15 minutes. Xiaomi even claimed that the results were qualified as new world records in the process. Xiaomi named the fast charging tech as HyperCharge.
According to Xiaomi, the battery should lose little under 20% of its capacity after 800 cycles, which is over two years if you do a full charge every day. If you go longer between charges it can stretch even more.
In addition, Xiaomi stated the Chinese authority demands at least 60% retained battery capacity after just 400 cycles, which Xiaomi greatly exceeds and no matter how slowly you charge, the battery will deteriorate after 800 cycles. It’s worth noting that battery degradation from charging at these surreal speeds will certainly be a big obstacle to overcome.
The company behind the 200W charging tech is NuVolta Technologies. NuVolta Technologies recently launched a second generation of its pump fast-charging chip. The NuVolta NU2205 is the fastest charging chip with the highest power output, capable of reaching 100W. Xiaomi is likely to be the first to actually put the tech in a smartphone.
