这个...自己不好断定 看你是送去哪里维修 对方靠谱不靠谱 我觉得如果是LZ现在的怀疑 真心不应该送去你现在的地方维修 iphone虽然就只有两颗螺丝固定机身 但是即便拧下来 没拆过机器的也是很难把前面盖启开的(从iphone5-6S都是跟4不同的设计)如果维修给你换了零件 也就是电池 换其他的从我本身觉得真心没有那么的必要 里面值点钱的 也就是屏幕 当然不知道你用的是什么型号 像什么指纹 蓝牙模块WIFI模块 摄像头 都有可能 这么说 如果维修是真心想换你点东西走 你也真心看不出来 机器维修好了之后 拿到机器先别走 看看之前的毛病还有没有 然后测试 麦克风 喇叭 前置后置摄像头 陀螺仪 WIFI 听筒 闪光灯 指纹 还有其他那三个按键音量大小 锁屏键 再有就是按住一个图标等它抖动 然后拖住图标在整个屏幕上拖动 如果拖动到一个点 图标自己返回原处那可能是排线有了问题 其他没啥毛病就行了
麦克风和喇叭可以打开语音备忘录测试 吹吹风 然后功放 听筒打112 陀螺仪打开指南针 其他的应该LZ都知道怎么测试 就不说了
楼上都是些不懂手机的居然还那么多人点赞！苹果手机每个零配件都有独立编码，如果被更换了，可以在爱思助手里查看出来。
