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

These fast charging systems don’t provide a continuous charge rate, but Xiaomi has been kind enough to connect their new charger to a power consumption monitor so we can see what’s going on. The phone charges to 10% in just 44 seconds, then quickly goes to 200 W. The phone hits a 50% charge in three ridiculous minutes. Then the phone slowly decreases the power, dropping to 150W and hitting 75% charge in five and a half minutes. Finally, the system drops to 40W to reach a full charge in eight minutes.

Behavior like this – gently recharging the battery during the latter part of the charge cycle – is intended to protect the longevity of the battery, and that’s part of the reason there is no proof this fast charge degrades your battery faster than a normal charge.

Xiaomi isn’t the only company pushing for faster charging speeds. Qualcomm announced 100W charging technology last year (although for some reason uptake of this feature has been very low), and Oppo is on the rise. up to 125 W. Xiaomi’s best commercial phones hit 120W. All of these systems use proprietary chargers at the moment, but with USB-C recently added support for 240W power, maybe we could. all agree on a standard? Please?

Xiaomi’s 200W charging demo used a ‘custom’ Mi 11 Pro. There’s no word yet on how to market the 200W charging, but Xiaomi’s 120W charging arrived on a commercial phone the same year it was demoed.
