苹果系统占用内存70GB，怎么办？别担心，解决方案来了
手机已经跟我们的生活密不可分了，而手机内存的问题也同样会给我们的生活带来一定的影响，如果内存空间过于少时，手机将出现卡顿、运行不流畅等等诸多问题，使得我们在操作体验上感觉非常差。在卡顿方面，很多人都会认为苹果手机不会卡顿，但是其实在存储空间不足时，苹果也是会出现卡顿，细心的果粉们会打开手机的设置后，看到了系统竟然占用了储存空间20到100GB不等，这可怎么办呢？
首先打开设置，
选择通用，
选择iPhone储存空间，
滑动到最底下，找到系统 右边就是所占据的内存空间。
正常来说，iPhone的系统只占用我们5-8G左右的空间，当发现iPhone超过这个正常值时，我们应该怎么办呢？
方法一：为了排除是系统误算，我们返回到通用后，再次进入iPhone储存空间，查看是否变回正常。如果依旧没有变化请通过以下其他方法操作！
方法二：清理APP文稿垃圾，QQ或者微信的聊天记录。IOS系统会将APP所占用的缓存也计入系统里。
解决方案：打开微信--我--设定--一般--储存空间--清除不需要的聊天记录等等信息。
方法三：插上电脑打开iTunes，连接后，锁屏什么都不用做，系统就会变小
方法四：将更新过没打开的App挨个打开，系统会变小
方法五：如果以上问题依旧没能解决，请做好重要文件的备份，并对iPhone进行【清除所有数据】
打开设置-通用-还原-抹掉所有内容和设置
方法六：经过OTA升级的小伙伴更加有可能出现这样的问题，那么将重要的文件做好备份，使用iTunes再次升级一次系统，系统就会变小。
方法七：设备进入 DFU 模式：确保机器处于开机状态，并连接至 iTunes，然后按你的机型进行下列操作：
iPhone 7 及以前机型
① 长按电源键和音量减键（6s 之前设备按住 Home 键） 10 秒，松开电源键；
② 持续长按 Home键或者音量减键，直到 iTunes 出现提示。
iPhone 8 及以后机型
① 点按一下音量上键，再点按一下音量下键；
② 紧接着长按电源键，直到 iTunes 出现提示。
在 iTunes 出现提示后，点击「好」，然后按住键盘上的 Shift 键（Mac 用户按住 Option 键），点击 iTunes 中的「恢复」，并选择刚才下载好的 .ipsw 格式固件；
等待 15 分钟左右即可完成刷机，中途保持手机和电脑的稳定连接，直至刷机完成后才能断开。
