USB Type-C出来这么久了，为什么还有手机不用？
手机的电源接口从原本单一的充电功能到现在的集成数据传输的功能，变化非常大，但是手机充电接口却改变不大，依然以Micro-USB接口为主，旗舰手机会用USB Type-C，而苹果则使用自家的Lightning接口。当然今天不说苹果，而是谈谈为啥安卓手机还不愿意大规模推广USB Type-C？
首先我们需要了解下什么是USB Type-C。USB Type-C是USB接口的四种类型之一，最大的特点就是正反都能插，与苹果的Lightning一样。USB Type-C是最近两三年才流行起来的，目前只有旗舰手机会采用这种类型的接口，比如小米、三星和华为。还有一些轻薄本会用到USB Type-C接口。
USB Type-C接口是未来的发展趋势，其功能和性能都要比目前主流的Micro-USB强得多，比如在充电方面，USB Type-C就可以支持高达100W的充电功率，更极端的还能做到双向充电，比如用手机给另一个手机充电，此外最方便的就是上文提到的正反插，根本不用考虑接口方向。而在数据传输方面，也比Micro-USB快了十几倍左右。
可见USB Type-C完全胜过Micro-USB，但为什么厂商不愿意普及？
其实USB Type-C不普及这个问题即是原因也是结果，为什么这么说呢，目前市面上的手机都以Micro-USB接口为主，而这些手机将近100%是中低端的千元机，千元机的销量远远超过旗舰机，所以如果你有一个带有Type-C接口的手机需要充电，很难找到可以借用的人。
此外，虽然有些手机使用USB Type-C接口，但其实也只是USB2.0的水平而已，就像买了辆跑车在赛道上却只开60公里每小时一样，是不是太浪费了？
安卓手机阵营不比苹果一家，对于苹果来说，用户粘性强，口碑好，销量大，强推Lightning接口，哪怕有损失，他也不在乎，所有人都得跟着改变。而安卓厂商不一样，使用成熟的Micro-USB即可能够减少手机设计和制造成本，这对于安卓厂商那些千元机来说才是合理的方案，有些用户可能看到你是USB Type-C接口就不买你的手机了，这也不是没有的事。
总之，USB Type-C接口的普及程度在旗舰手机上是比较高的，只是千元机因为成本问题不愿意推广而已，不过，随着手机性能的不断提升，Type-C接口迟早是会替代Micro-USB成为主流的。
