Earlier this week, Huawei published a YouTube video demonstrating a relatively new quick charging technology developed by its own Watt Lab division, capable of recharging 48 percent of a smartphone’s battery in just 5 minutes. There are, however, a couple of caveats, and for starters, it must be stressed that this isn’t really a new technology. Huawei’s Watt Lab actually developed this solution back in 2015 and the recent YouTube video even contains some older footage. But with MWC now being just around the corner, the reason why Huawei may have brought this technology back into the spotlight could be that the company intends on introducing it to a wider audience at the upcoming event in Barcelona, Spain.
Another aspect that needs to be considered is the fact that, judging by Huawei’s demonstration, the solution requires a smartphone equipped with a user-removable battery. In fact, the demonstration seems to have been made using a custom battery featuring additional connectors, which is one way to achieve faster charging. And thirdly, the video makes no mention of the demo unit’s battery capacity, though according to previous reports from a couple of years ago, the unit should be able to hold a 3,000mAh charge. Nevertheless, Huawei’s latest video claims that this new quick charging technology represents a major breakthrough, and the solution is expected to be employed by a wide variety of product categories, ranging from the usual smartphones and laptops to mobile power banks, and even electric vehicles. With that in mind, it seems that Huawei’s solution may have been further refined over the past couple of years and it might now be ready for commercialization.
As far as smartphones are concerned, it’s evident that most devices today feature a unibody or enclosed design with a non-removable battery. Even Samsung eventually made the switch to an enclosed design with the past couple generations of its Android flagships. Having said that, it’s highly improbable for smartphone designs to make a comeback to user-removable batteries for the sake of a better quick charging solution anytime soon, but over the past few years, Huawei’s Watt Lab could have shrunken the technology enough to be employed by today’s unibody handsets. Only time will tell whether that's the case, and perhaps Huawei will provide more answers at MWC in late February when the company is also expected to unveil its AI-focused P11 flagship that may also be marketed as the P20.
