2022年年底，小米正式发布了MIUI14，说MIUI14可以删除8个核心应用以外的所有应用。然而我更新MIUI14后，并不像说的那样，再一次被当猴耍了。转念一想，国产的room怎么会做到这么良心呢？

一、MIUI14的大饼

    首先，官网确实有说法的，"不可卸载应用仅8个"，以下是MIUI14高大上的『锐意新生』官网：

MIUI 14 锐意新生更轻巧 / 更流畅 / 更安全 / 更人性化https://home.miui.com/    这是我从官网截取到的【系统占用 大幅精简】部分的视频：

    不过，网上也有不一样的声音，比如：

2022年10月之后新发售的小米手机才支持卸载。

     再比如：

不可卸载的应用仅8个，指的是桌面有图标但是不可卸载的应用。

    总结一下：仍然删不了绝大多数的垃圾系统应用，特别是一些没有图标在后台一直运行占用大量内存的无用系统app。

二、adb shell pm卸载应用

    既然官方仍然不支持，我们有没有什么简单的方法去卸载这些不使用的应用呢？当然是可以的，本篇通过adb shell pm 命令去删除小米手机自带的系统应用，其他Android手机类似。

    拿小米举例子，很多小米内置的应用在应用管理界面可以删除的，例如红外遥控，多看阅读等，而且卸载后也可以通过小米应用商店下载。所以，本篇讲的主要是如何卸载那些不同通过应用管理面板去卸载的应用。

    当然，怕万一删除了重要的系统应用导致变砖，我拿我的备用机红米k30机器去做。在卸载之前，有312个应用程序。

通过adb shell pm list packages > test.txt，导出所有已安装应用的包名。如下：

    可以看到，内置的app非常多，其中有一些是核心应用，比如打电话发短信这种。还有一些例如小米视频、音乐等自带的实际可被第三方替换的应用。另外一些就是没有图标的后台运行占用内存的应用。

    不多去废话，直接切入正题。卸载的命令：adb shell pm uninstall --user 0 包名，例如卸载小米视频：

adb shell pm uninstall --user 0 com.miui.video

    运行后，显示success则卸载成功：

     如果包名输入错误，则卸载失败，例如：

    上面我们也导出了所有应用的包名，包名一共有300多个，如何知道每个应用的包名呢？这里给大家介绍一个容易被忽视的细节：

进入应用管理界面，点开打算卸载的应用，以壁纸为例（当然，壁纸是不建议卸载的）：

 2. 点击右上角那个带圆圈的i，就可以看到包名：

三、卸载后无影响的应用List 

    在卸载的过程中，也出现了几次问题。比如我卸载了查找设备后，导致一直弹toast。目前已经确认删除后没有什么不良反应的包名（长期更新）：

adb shell pm uninstall --user 0 com.miui.videoadb shell pm uninstall --user 0 com.miui.playeradb shell pm uninstall --user 0 com.miui.contentextensionadb shell pm uninstall --user 0 com.xiaomi.gamecenter.sdk.serviceadb shell pm uninstall --user 0 com.miui.touchassistantadb shell pm uninstall --user 0 com.miui.yellowpageadb shell pm uninstall --user 0 com.miui.accessibilityadb shell pm uninstall --user 0 com.xiaomi.mi_connect_serviceadb shell pm uninstall --user 0 com.miui.personalassistantadb shell pm uninstall --user 0 com.miui.voicetriggeradb shell pm uninstall --user 0 com.miui.hybridadb shell pm uninstall --user 0 com.android.printspooleradb shell pm uninstall --user 0 com.xiaomi.powercheckeradb shell pm uninstall --user 0 com.xiaomi.mtbadb shell pm uninstall --user 0 com.xiaomi.paymentadb shell pm uninstall --user 0 com.mipay.walletadb shell pm uninstall --user 0 com.miui.cloudbackupadb shell pm uninstall --user 0 com.android.quicksearchboxadb shell pm uninstall --user 0 com.miui.tsmclientadb shell pm uninstall --user 0 com.xiaomi.xmsfadb shell pm uninstall --user 0 com.miui.nextpayadb shell pm uninstall --user 0 com.xiaomi.migameserviceadb shell pm uninstall --user 0 com.miui.carlink可选（投屏、互传）：adb shell pm uninstall --user 0 com.milink.serviceadb shell pm uninstall --user 0 com.miui.mishare.connectivity小爱adb shell pm uninstall --user 0 com.miui.voiceassistadb shell pm uninstall --user 0 com.xiaomi.aiasst.visionadb shell pm uninstall --user 0 com.xiaomi.aiasst.service

    注意，卸载后不会删除原有的安装包，所以内存并不会有显著的减少，且恢复出厂设置后这些内置的app也会再次被安装。
