Edward Tian, the head of the Charging Technology Lab at Oppo, made the claims in an interview with TechRadar.
Tian told the website: "As a technical engineer in the fast-charging field, for me, my work is to break limits. We will continue to explore until one day phones can be fully charged in one second."
Tian was speaking ahead of the launch of the Oppo Reno 8 smartphone. The Oppo Reno 8 and 8 Pro are set to debut a new feature designed to optimize charging and battery use known as the Battery Health Engine.
Tian said that the Battery Health Engine feature could improve charging speed while at the same time retaining overall battery health. He told TechRadar that "simply speaking, the Battery Health Engine can help the battery to maintain its most comfortable status while charging, just like we do things at a comfortable pace without rush".
In the interview, Tian also noted that fast-charging can sometimes adversely impact battery lives, saying that "fast charging can result in bigger battery sizes because, to charge faster, you need to use battery cells with a higher C-rate, which leads to lower energy density."
According to Tian, improving the charging speeds of phones “is only meaningful when the battery life is solid."
