iqoo is a sub-brand of vivo, its charging protocol is the same as vivo's charging protocol, that is, vivo flash charging dual-engine protocol, dual-engine flash charging technology is a mobile phone fast charging technology, which is developed by vivo under the premise of compatible international mainstream fast charging protocol. The dual-engine flash charging technology uses the dual-charging chip parallel charging method, which is 2 times faster than the ordinary charging technology, and has nine safety protection technology. Media experiment data show that under the dual-engine flash charging technology, the phone's power is from 0% to 19% after 10 minutes of charging, and 60% of the power is completed within 35 minutes.
