一直有传说,手机壳可能会影响手机信号,到底真的假的呢?有一天,在一个阴暗空旷冷清的博物馆里,小编掏出了自己的iPhone4,居然没有信号!!!然后,他把手机壳摘掉了,再看,有3格信号了!一个手机壳能有这么大的影响么?换个iPhone6 Plus试试。装上金属壳,信号变成两格了!不光是苹果,红米2也是一样的,装上金属壳就掉一格信号

一直有传说,手机壳可能会影响手机信号,到底真的假的呢?有一天,在一个阴暗空旷冷清的博物馆里,小编掏出了自己的iPhone4,居然没有信号!!!

然后,他把手机壳摘掉了,再看,有3格信号了!一个手机壳能有这么大的影响么?

换个iPhone6 Plus试试。装上金属壳,信号变成两格了!不光是苹果,红米2也是一样的,装上金属壳就掉一格信号。

于是,我们找到浙江大学信息与通信工程博士雷鸣。

用专业仪器测一下,结果是这样的――

每一款手机,在装上金属壳之后,信号下降10个dbm,这是个什么概念呢?简单地说,就是刚好一格信号。

而硅胶和塑料壳对手机影响不大。

不仅仅是信号,金属壳对手机的GPS、上网都可能造成影响。

所以,如果你老觉得信号不好,换个塑料壳试试看!
