And now without wires
Fast charging has become one of the attractions of many phones, so manufacturers are working hard to find technologies that allow it to do so as soon as possible. In any case, the solutions always go through the wired mode, however, Xiaomi seems to have hit the key when creating a quite powerful wireless charging system.
To be exact, new technology would allow a phone to be charged with a 80W power, allowing to reach 50% of a 4,000 mAh battery in just 8 minutes of charging. But it is that, if that were not enough, this charge would be able to complete 100% of the battery in just 19 minutes, a really spectacular figure, since it would almost maintain the charge rate per minute from 0%.
Charging at 80W without cables
To prove it, Xiaomi has presented a video in which it shows a modified Mi 10 Pro, where you can see that with only the first minute charging device is capable of passing 0% to 10%, and after another seven minutes, the phone already had 50% full charge. That is to say, half charge in 8 minutes.
As you can see, the system is incredibly fast, and would largely solve the bondage of relying on a plug for long periods of time due to the slow charges of some charging systems. Combined with an external battery with wireless charging, it would be a perfect solution for those addicted to mobile.
And how about efficiency?
Another issue will be the energy efficiency of this load. Wireless charging systems are notorious for not being too efficient, as charging coils often waste energy due to physical reasons. Taking into account the 80W power available in the system, this energy loss could be higher than that of other systems with lower load, so this would be another important point to improve in future developments.
When will it be available?
For now, what Xiaomi has presented is an experimental prototype that could be far from commercialization, and if we take into account previous presentations, we are still waiting to see the 40W and 50W wireless charging systems in stores, which were already presented with similar demos and that have not yet been implemented in any device (for now the maximum wireless load offered works at 30W).
So for now we just have to keep waiting. Charge a phone with 4,000 mAh battery in just 19 minutes? Where to sign?
