By introducing ever faster chargers, smartphone manufacturers are shaking up old habits. No need to leave your phone plugged in all night. A few minutes are enough. At Xiaomi, we could soon beat a new record.
If smartphones are becoming more and more powerful from all points of view, the battery remains an element that has not changed much. At Xiaomi, we plan to recharge it in just a few minutes.
Recharging time: a false solution
Certainly, over the years, we have managed to improve the autonomy of smartphones in different ways. On the one hand, since we are able to miniaturize the other components, it can take up more space and therefore grow. The operating system, whether it is iOS or Android, also offers better autonomy management. And then there is the charger. And at this level, the manufacturers are betting on an ever shorter recharging time. Note, however, that several studies, like this one, tend to show that fast charging affects battery life. The heart of the problem, namely the chemical components of the battery, has not yet been solved, although work has been going on for years.
Recently, by launching its OnePlus 8T, the manufacturer OnePlus introduced a 65W charger promising to increase the battery from 0 to 100% in just 39 minutes. A few days later, with its Mate 40 Pro, Huawei delivered a 66 W charger. At Xiaomi, we also like to take up challenges.
Xiaomi, soon the first to charge at 200W?
In October, the manufacturer lifted the veil on an 80 W wireless charger. The latter would recover 10% of the battery in 1 minute, 50% in 8 minutes and 100% in just 19 minutes. As for wired charging, Xiaomi formalized in August its Mi 10 Ultra with a 120 W charger offering a full charge in 23 minutes. It is also the first to have introduced this technology.
For now, this unofficial information obviously remains to be taken with a grain of salt, but in theory this would allow us to go below the 15-minute mark. One of the major challenges is of course to control the impact of such recharging power on battery life. Probably for this reason, at Apple, we have just introduced 20 Watt charging for the iPhone 12.
