4)充电器解码FSK信号并发出Accept消息给手机,同时调整PowerSupply的直流电压和电流输出; 5)手机收到Accept消息,调整ChargerIC的充电电压和电流; 6)手机在充电过程中可以动态发送Request消息来请求充电器改变输出电压和电流,从而实现快速充电的过程

记得看快充协议,以及要求的线材(比如OPPO的线材就是不一样的,普通的type-c线也分2A\3A\5A等规格,一定要买比快充所经过电流大的A数才能保证你的手机可以快充且安全!)只有快充协议和线材这些都满足了你的手机才能真真实现快充。

严格上讲,Android系统实际上是运行于Linux内核之上的一系列"服务进程",并不算一个完成意义上的"操作系统";而这一系列进程是维持Android设备正常工作的关键,所以它们肯定有一个"根进程",这个"根进程"衍生出了这一系列进程。这个"根进程"就是init进程。
