Huawei unveiled its latest update to its Android skin, EMUI 11, at its 2020 Developer Conference. This involved a teaser video that contains a shot seeming to reference 66 watt (W) charging. This goes beyond the current upper limit of phone power-brick speeds for this OEM; therefore, this spec may be destined for the upcoming Mate 40 flagship series.
