On social networks, Xiaomi President Lin Bin showed a new technology that charges smartphone batteries with 100 watts. This allows a 4,000 mAh battery to be fully charged in just 17 minutes.

This would make Xiaomi's fast charging technology almost twice as fast as Oppo's SuperVOOC, which can be found in Oppo's R17 Pro and is currently the fastest charging technology for smartphones on the market. For comparison: Huawei's SuperCharger technology (55W) of the folding smartphone Mate X allows the 4,500 mAh battery to be brought from 0 to 85 percent within 30 minutes.

Even here it remains to be seen how long the entire charging time will be, because it is precisely these final percentages that Huawei does not specify and that always take much longer to charge. Therefore, many manufacturers generally avoid specifying the complete charging time and usually only talk about the first 30 minutes or the charging time for the first 50 percent.

Unfortunately, Lin Bin doesn't reveal in his Weibo-Post which smartphone the teaser is about. So the big question here is when will we see the first device with the technology? After all, such a 4,000 mAh battery offers enough battery life to leave a device off the wall socket for two days if used moderately.

In addition, it remains to be seen how the 100W charger will handle the heat. And does the charging technology, as with Oppo and OnePlus, fit into the power supply itself? How thick will it turn out to be? What are the consequences of this super fast charging for the battery? All these questions are currently still unanswered, but there will probably be addressed at today's Xiaomi event.

Let us know what you think the answers to the unanswered questions will be in the comments below.

    If a battery is not "designed" top down to handle that burst of current in that short period of time, I think it's going to have issues down the road. Impact on battery life being the greatest. The "spacing" between the anode & cathode inside the cells of a battery are becoming smaller & thinner as phones get thinner. They are literally squeezing as much space for the battery into thin devices (see what happened to the samsung phone a couple years ago?) Then some iPhones bend, and they keep making them thinner and thinner. Bend a battery, as critical as they are and then start souping up the current to charge it in a short period of time, is a disaster waiting to happen. My last 3 phones came with quick chargers, and I never bothered taking them out of the box. I just connect the USB cable to my computer and let it set for 3-4 hours or more to slow charge.

    Charging a phone that fast has to have repercussions??
