Leading the charge: Huawei develops fast-charging tech for batteries

Quick café stops could quickly recharge the batteries of something other than your brain in the near future. A fast-charging technology developed by Huawei’s Watt Lab is said to bring batteries from empty to half-full in five minutes, depending on the size of the battery.

The technology was revealed during the 56th Battery Symposium in Nagoya, Japan by the Central Research Institute at Huawei Technology Corporation Limited. This technology can permit an empty 600 mAh capacity battery to be charged to 68 percent capacity in two minutes. A much more potent 3,000 mAh battery, of the type likely to be found in a smartphone, can be charged to 48 percent capacity in as little as five minutes. A sample of this can be seen in the video above.

To achieve this level of fast charging the researchers bonded heteroatoms to the molecule of graphite in anode. That then acted as a catalyst for capturing and transmitting lithium through carbon bonds, all without supposedly decreasing energy density or battery life. Huawei says that it believes this technology will lead to a “revolution in electronic devices” such as “mobile phones, electric vehicles, wearable devices, and mobile power supplies.” The batteries have been throughly tested and are certified by Huawei’s terminal test department.

Charging technologies have made many advances recently, fast charging being one and wireless charging another. With the introduction of this super version of wired fast charging it looks like we might not need to worry about our phones running out of juice in the near future. For those with smartwatches this should also come as a welcome surprise, considering the lesser capacity batteries, it would be possible to fully charge your watch before your order at a restaurant or café has even reached the table. Have you ever woken up a sunny morning only to come to the dreadful realization that you forgot to charge your device during the night? No problem, just charge it up while you eat your breakfast or while you’re getting dressed.

While all of this sounds fantastic, there’s no word from Huawei on when you can expect this technology to hit the market. But considering that it’s ready to be displayed online, that might not be as far off as it sounds.

Watts don’t matter when fast charging your phone — time does
Realme GT Neo 3 with its box, showing the information on the back.

The race to have the highest-wattage battery charger is firmly on among many smartphone makers. Yet quoting wattage is confusing and technically questionable, and we shouldn’t be sucked into believing this number matters, or thinking it tells us anything remotely informative.

What’s most frustrating is there is a far more helpful number that perfectly captures what’s great about fast charging just waiting to be more widely used, and it’s one that everybody understands.
Big numbers
Wattage is the megapixel of our times, with manufacturers touting bigger numbers as better, without actual clarification. Here’s how crazy it’s becoming. The Realme GT Neo 3 comes with a 150-watt charger in the box and the OnePlus 10R does too, while the Poco F4 GT comes with a 120W charger, as does the Xiaomi Redmi K50. The OnePlus 10 Pro has an 80W charger internationally and a 65W charger in the U.S., while the Oppo Find X5 Pro has an 80W charger too. The Honor Magic4 Pro comes with a 100W charger in the box, but you can buy a 135W charger separately, and it’s also compatible with a 100W wireless charger.

All these outlandish battery life claims are getting silly
Man relaxing while holding OnePlus Nord N20 phone plugged into charging cable.

How long does the battery in your chosen device last? Whether it’s a smartphone, fitness band, smartwatch, laptop, or anything else, has it met or exceeded the claim made by the manufacturer? I’m willing to bet it hasn’t, or at least doesn’t do so on a regular basis, and that’s because many battery life figures published these days seem to be plucked out of thin air, and then a situation is constructed around it to make it work.

It's all getting rather silly, but is there anything that can be done about it?
Battery life information matters
Knowing the approximate length of time the battery lasts in our mobile device of choice is important. It informs us about whether it’s OK to skip charging if we’re short on time, if we must take a charger on a long weekend away, or if using a phone for GPS in the car will kill it before arriving at our destination.
