vivo X6双引擎闪充是什么?和快充技术有什么区别?
昨天晚上步步高vivo发布了X6和X6 Plus两款安卓手机,前者是5.2英寸的而后者是5.7英寸的机器,卖点是64位八核心处理器(就不告诉你是什么品牌的处理器)、4GB大运存、指纹解锁、HiFi和双引擎闪充。不知道有多少读者跟我一样对于这两款长得很像iPhone 6的三千元安卓手机完全无感,但这两款机型的卖点之一&&&双引擎闪充&还是成功吸引了我的注意,据说这个功能可以提供两倍的充电速度,那么它到底是什么样的一种技术,和我们之前介绍过的快速充电技术又有什么区别。
vivo官网对于&双引擎闪充&列出了四大优势,分别是国际通用、高效、便捷和智能。国际通用指的是&采用国际通用标准,方案更加成熟,量产经验更加丰富&,然而这句话的范围有点大,国际通用标准是哪个标准呢?vivo没有告诉我们。高效指的是&采用了双充电芯片和双充电电路&,带来两倍的充电速度提升。便捷指的是&兼容行业标准USB线&,通过vivo官方的图片可以看到X6和X6 Plus两款手机仍然采用MicroUSB接口,虽然说MicroUSB接口普及率高,采用MicroUSB接口足够让用户得到便利,随手就能找到充电线材,但从一个技术控的角度来讲,都2015年底了,不采用对电流规格支持更强的USB Type-C接口说不过去,要知道USB规范中MicroUSB导电的Pin1、5最大支持1.8A电流,业界做到2A也是稍微高出规范。最后一种优势是智能,&根据手机使用情况管理充电电流&,不同的手机厂商对于电源管理的细节也不同,例如有些手机会在使用期间减少充电电流大小,关闭屏幕时则提高充电电流,为的是减少发热,vivo采用什么电源管理我们同样无从知晓。

从网友拿到的vivo X6来看,它所搭配的充电器规格为5V/2A和9V/2A两种,不像是高通QC2.0和MTK PEP的快充还带一档12V,vivo官方也没有告知X6的处理器品牌,所以我们也无从判断它使用的是高通的QC2.0、MTK的PEP还是vivo自主研发的充电技术,但这些已经不重要了,18W的功率已经足够大了,相当于普通的5W充电器(5V/1A)的3.6倍,充电速度往翻倍完全不是问题。从其他媒体的测试来看,2400mAh的vivo X6充满耗时约80分钟,和我们测过的一些9V/1.2A、5V/2A的机型充电速度相当,不过充电前期的速度还是很快的。
&能不能给我一首歌的时间&
至于手机内部是否用了2套充电电路,那就看厂商的权衡了,高通的QC以及MTK PE的手机不采用两套充电电路同样也能快充。两套充电电路意味着更高的成本,但会带来更低的损耗。vivo的兄弟品牌OPPO的闪充更像是实际意义上的&双引擎&,用的是8触点电池和7Pin的定制USB接口,充电电流高达4.5A,相当于配上了&两倍&的充电电路。
&双引擎闪充&在手机设置菜单的开关
&双引擎闪充&在手机设置菜单中还有一个单独的开关,至于是否有效,或者说它只是一个给消费者的心理暗示,仅仅是作为一个宣传手段,那得以后有机会测试了才能下结论。最后附上vivo官方的&双引擎闪充&视频,拍得挺有趣。
