Xiaomi shows through the co-founder and President Bin Lin, the progress made by the young company in the rapid charging technology. At 100 watts, a prototype smartphone with a 4,000 mAh battery will be fully charged within 17 minutes.
A stronger power supply than the notebook
The short clip that Xiaomi has distributed on Weibo shows how to load the prototype on a 100 watt power supply. The power supply would thus be more powerful than many notebooks that work with 45-, 60- or even 90-watt power supply – only gaming cars are significantly higher. That works in the lab Super Charge Turbo even with the smartphone, the powerful power supply ensures a very fast full charge.
The fast charging technology for smartphones has matured significantly in recent years, 20 and 25 watts, almost every modern device, but LG & Co need for more than 4,000 mAh two hours. The competitor chosen by Xiaomi in the video, an Oppo R17 smartphone with SuperVOOC technology, which represents the fastest solution in series so far, loads at least 65 percent of a 3,700 mAh battery in the same time of 17 minutes on a 50-watt -Power adapter.
Questions remain after the video but primarily after the durability of the battery and the heat generation, which is undoubtedly created in a technical device on a 100-watt power supply. Many smartphones can get very hot on the charger these days and use them at the same time, but at the same time, batteries may suffer from shorter lifetimes. These may be the primary sites of the developers of this technique. Qualcomm had recently shown with Quick Charge 4+ as the latest wireless charging solution, that a 2,750 mAh smartphone battery can be charged wireless from 0 to 50 percent within 15 minutes, with maximum performance in compliance with the 40-degree Temperature limits is retrieved. Xiaomi had revealed to the MWC 2019 the Mi Wireless Charging Pad, which loads wirelessly with 20 watts and thereby should meet all current standards.
An appointment for Xiaomi products with the 100 watt charging technology does not yet exist. Eventually, a company will also try again at an intermediate step, which is just over 50 watts, the Oppo offers.
