I thought the Huawei Mate X’s 55-watt quick charging tech was crazy for loading up a battery from 0 to 85% in just 30 minutes, however, a new 120W tech introduced yesterday at the Mobile World Congress Shanghai 2019 is completely insane, fully charging a 4,000mAh battery in just 13 minutes.
The technology is named Super FlashCharge 120W, and Chinese phone manufacturer Vivo makes it — recognized for pushing the technology envelope with phones like Nex, Nex 2, or its latest Apex prototype. Vivo makes use of a customized Type-C data cable and 120W charger (20V/6A). The technology only takes five minutes to charge the same battery as much as 50%.
Vivo’s Super FlashCharge beats Xiaomi’s 100W charging technology, which claims can fully charge a battery of the same capacity in 17 min. However, both technologies haven’t been implemented yet in any commercial product. Recently, scientists found the reasons why batteries die faster the faster they charge, so perhaps both companies are attempting to figure out the long-term effects of such technologies.
The fastest delivery charging tech is Oppo’s 50W SuperVOOC. Huawei planned to launch a 55W charging with the foldable Mate X this summer. However, that phone has been delayed. For comparison, Apple’s iPhone USB-PD 29W fast charging can load the iPhone XS’ ridiculously tiny 2,658 mAh battery from 0 to 50 % in half-hour.
At this time, there is no technical information about how Xiaomi or Vivo plan to compensate for the long-term deterioration of quick-charging batteries’ molecular structure. There is additionally no figures published about how long these batteries will last without considerably reducing their capacity. But we do look ahead to seeing this tech show up in phones so we can test it out.
