A new trademark application from vivo just popped up on EUIPO (European Intellectual Property Office). It appears that the company is readying a new fast charging tech under the name Super FlashCharge. It's safe to assume that the upcoming fast charging tech from vivo would reach 55W as per previous rumors. Perhaps vivo is readying its next high-end smartphone with competing charging tech on board. The highest we've seen so far is 65W on the Oppo Reno Ace but 55W is also pretty fast and should easily top a 4,000 mAh battery in about half an hour. Via
