Xiaomi has just shown a new highlight for smartphone charging: a 200W charging system. The company demonstrated “Xiaomi HyperCharge” in a new twitter video this weekend, saying the new technology can blast a phone from empty to full in eight minutes. That’s about as long as a trip to the gas station.

These fast charging systems don’t offer a continuous charging rate, but Xiaomi was nice enough to hook up its new charger to an electricity usage monitor so we can see what’s happening. The phone charges to 10 percent in just 44 seconds, then ramps up quickly to 200W. The phone charges to 50 percent in a ridiculous three minutes. Then the phone slowly reduces the power to 150W and reaches a 75 percent charge in five and a half minutes. Finally, the system drops to 40W on its way to a full charge in eight minutes.

This kind of behavior – gently topping up the battery for the last part of the charge cycle – is meant to protect battery life, and it’s one of the reasons there’s no evidence that fast charging will degrade your battery faster than normal. to upload.

Xiaomi is not the only company pushing for faster charging speeds. Qualcomm announced 100W charging technology last year (although for some reason the adoption of this feature has been very poor), and Oppo is up to 125W. Xiaomi’s best commercial phones reach 120W. All of these systems use proprietary chargers at the appropriate level. way now, but with USB-C recently adding support for 240W power delivery, maybe we can all agree on a standard? Please?

Xiaomi’s 200W charging demo used a “custom” Mi 11 Pro. There is no word yet on the commercialization of 200W charging, but Xiaomi’s 120W charging came to a commercial phone the same year it was showcased.
