Battery life is one of the biggest headaches in tech—but while capacity remains a problem, manufacturers are at least making big improvements to charge times. Like Huawei, whose new experimental set-up can take a dead battery to 48 percent change in about five minutes.

The Chinese smartphone manufacturer has developed a lithium-ion battery with a graphite-coated anode that can withstand the stresses of incredibly fast charges. Its 3,000mAh prototype—which is about the size of battery you’d find in a large smartphone—can be charged by 48 percent in just 5 minutes. It also has a much smaller 600mAh battery that can be charged to 68 percent in 2 minutes.

Recently, Qualcomm announced that the third iteration of its Quick Charge technology, which will be baked into its 2016 chips, will feature a new Intelligent Negotiation for Optimum Voltage algorithm that can charge a dead phone to 80 percent of charge in just 35 minutes. It’s unclear how sophisticated the charging software in use by Huawei is.

Currently, the Huawei set-up is bulky and requires a special charger, both of which would need to be addressed before it found its way into a real product. There’s no word about if or when the new Huawei battery hardware may become a commercial reality.

48% in 5 mintues. 68% in 2 minutes. Those are some weird numbers to give out.

I’m guessing charging is faster at the start and slows down as the battery gets full. That makes these the most impressive numbers overall and that’s why we’re hearing them.
