Xiaomi just had their own tech demo on Twitter, and it is amazing. It was more like Xiaomi showing off their latest charging technology. In the video, Xiaomi charged a Mi 11 Pro with 4,0000mAh battery in 8 minutes. They also announced that they also have a new more powerful wireless charging technology that can charge the Mi 11 Pro in 15 minutes with 120W.
Charge up to 100% in just 8 minutes using wired charging and 15 minutes wirelessly! #XiaomiHyperCharge

To be fair, fast charging technology has received plenty of attention in recent years. Modern flagships have to charge faster every year. The charging speed race technically was kicked off by most of the Chinese manufacturers like OPPO and Xiaomi. OPPO, of course relies on their own VOOC charge technology. Their commercially fastest charging products charge at 125W at the maximum.
In some sense, the charging speed race has been an exciting one to say the least. The wonders of fast charging technology have given us users the freedom of leaving your device on the charger for two hours or less and get going for the rest of the day. It has also freed us from sitting near a wall socket for long hours at a time. With Xiaomi’s demo, you probably can expect to charge a similar smartphone within a minute in a few years’ time.

Here is the thing though, that much displacement of electricity at one go is going to generate a lot of heat. While the speed at which the battery is being charged will cause more wear to the battery itself, the heat produced could also cause extra wear on the battery. More heat will also lead to less stability and in some cases, fire or explosion. In that case, there could be safety and durability problems that manufacturers will soon have to work with before they can push battery charging speeds to 200W and above.
Xiaomi’s tech demo is not an indication of when they will equip devices with 200W charging capabilities. 120W wireless charging mentioned does not also have an implementation date at this time. By the looks of it though, the charger technology is ready for prime time. That also means that we can expect Xiaomi to launch charger products that will charge faster than 120W and fast wireless charging at more than 80W.
