4200mAh+40W超级快充 VS 4000mAh+44W超快闪充，实测告诉你怎么选
近几年手机市场发展愈发迅速，各项黑科技“横空出世”，惊艳了行业内外。比如iPhone的3D结构光，vivo的屏幕指纹、零界全面屏+升降式摄像头等等，都是行业领先级别的创新技术。似乎一切都在满足消费者越来越挑剔的需求，唯独续航不尽人意，尤其是旗舰机上，轻薄机身与超大电池相悖。有些厂商便通过发展快充技术来“曲线救国”，然而目前市面上的快充技术也很少有令人满意的。在如此大环境下，大容量电池加大功率快充的旗舰机就更加受到青睐了。比如去年下半年发布的华为Mate20 Pro和最近点燃消费者购买热情的iQOO，在续航、快充方面可以说是旗舰机中的佼佼者。

续航最根本的因素在于电池，要想拥有持久的续航，大电池是绝对不可少的。目前市面上大多数旗舰机的电池容量仅在3000mAh多一点，在3500mAh以上的寥寥无几。4000mAh对于旗舰机可以说是一道门槛，华为Mate20 Pro和iQOO都跨过了这个门槛，它们的电池分别为4200mAh和4000mAh，可以说是很大的惊喜。

除了大电池，两款手机的快充功率也是不容小视的。华为Mate20 Pro带来40W超级快充，iQOO则采用44W超快闪充。初步发现，电池容量上华为Mate20 Pro小胜，充电功率则是iQOO更猛。

我们首先来测试快充，先将两款手机电量耗至1%，然后开始充电。通过我们记录的数据，到充满电的整个过程，华为Mate20 Pro耗时69分钟，iQOO花费45分钟。
根据充电过程中每10分钟记录的数据，我们作了一个表格，可以更直观地看到两款手机的快充效率。iQOO电池容量仅比华为Mate20 Pro少200mAh，但是iQOO的44W超快闪充比Mate20 Pro的40W超级快充威力更大，转换效率明显高上不少。
既然充满电了，就直接测试两款手机的耗电如何，我们选取了几个比较有代表性的APP。首先是在腾讯视频观看1小时的720P视频，华为Mate20 Pro耗电9%，iQOO则是7%。

然后是刷微博，1个小时后，华为Mate20 Pro耗电14%，iQOO为10%。

王者荣耀虽然比起前两年热度下降很大，不过依然还是很多人常玩的游戏。经过1个小时的王者峡谷作战，两款手机耗电都是17%。

刺激战场是目前最热门的吃鸡游戏，对于性能的要求更高，耗电也是比较高的。1个小时的吃鸡后，华为Mate20 Pro耗电17%，iQOO耗电为18%。

华为Mate20 Pro的4200mAh电池和iQOO的4000mAh电池是很接近的，都属于超大电池，200mAh的差距并不大，最终谁的耗电控制更好，也得益于系统节电机制以及处理器功耗，总体来说，iQOO的续航比起华为Mate20 Pro还要好一些。
华为Mate20 Pro的4200mAh电池+40W超级快充，iQOO的4000mAh电池+44W超快闪充，都是值得肯定的，更在旗舰中起到了表率的作用，这样的旗舰机值得点赞。当然，通过对比，iQOO的44W超快闪充效率更高，而且续航表现上其4000mAh电池并不输于华为Mate20 Pro的4200mAh电池，iQOO称得上旗舰中的续航标杆机。
