买手机别被套路了！看懂这几个参数，手机好坏就稳了
一部手机性能好不好、使用寿命长不长，该怎么衡量呢？听取其他使用者的意见固然很重要，可是最重要的还是靠自己精准鉴别。那接下来就看看买手机该认准哪些参数吧！
1. CPU
不管是手机还是电脑，CPU可以说是决定它们性能好坏的核心部件。现在比较普遍的就是骁龙、Exynos、麒麟和苹果的A。它们还分为不同的型号，并不是哪一大类好它所包含的全部型号的CPU处理起来就快速，具体还是要通过具体的型号对比来判断。但是就整体来说，大众所熟悉的苹果A、骁龙和麒麟算是佼佼者。
2. 内存
内存可以分为RAM和ROM。RAM叫做随机存储内存，ROM叫做只读内存，简单的来说，它们在电脑中相当于内存和硬盘。内存用来运行程序和交换数据，硬盘用来存储文件数据。ROM太小会导致手机卡壳，RAM太小就会导致安装不了过多的应用，所以，内存对手机性能好坏的影响可以说是十分大了。现在常见的配置就是6GB+64GB。
3. 电池
电池的续航能力对于许多人来说再重要不过了，毕竟大家都不想每隔一会儿就给手机充一次电，所以电池的容量也是挑选手机的必看参数。现在市场上大部分的手机电池容量在3000+mAh，好一些的会超过4000mAh。当然，现在一部分手机能实现快充的功能，对于手机的耗电缺陷也是一个较好的补救措施。
4. 相机
照相是手机中一个比较重要的功能，所以手机摄像头的像素也是值得买家关注的。决定摄像头拍出来的相片是否清晰、真实是由像素、光圈、分辨率以及内部的传感器元件决定的。
分辨率越高，图像效果越好，但是相对占的内存也越大。传感器又分为CCD和CMOS，CCD成像质量较好，但是相对较昂贵，CMOS的图像质量虽然稍逊色，但它的耗电量低，较便宜。购买者可以根据自己的需要选择。
5. 屏幕
屏幕是实现人机交互的中介，因此选择一个体验感好的屏幕至关重要。现在的手机屏幕主要分为LCD和OLED。LCD屏幕是我们比较熟悉的液晶显示屏，它的缺陷是必须通过背光才能显示图像，现在在手机市场中的发展已经比较成熟。OLED与LCD相反，它能够自发光，即不需要背光，且相对于LCD屏幕来说，它的对比度和反应速度十分高，功耗较低，较LCD好一些，但还未全部涵盖手机市场。
除了材质之外，影响屏幕体验感的还有对比度、色域等。色域越广，色彩层次越多，即显示的越饱满。对比度越高，色彩的饱和度也就相对提升。
手机的使用感由多方面组成，除了以上所讲述的，还有一些因素由个人喜好决定。根据这五个必备参数，再加上个人要求，挑选出来的手机准不会错啦！
