一个恼人的问题是，upower将需要几分钟或更长时间来更新我的电池状态(这个问题类似于这个职位，但我提供了我的笔记本电脑的详细信息)。这意味着，如果我从冬眠中唤醒我的笔记本电脑，它会在几分钟内显示出错误的电池百分比，而当我插入充电器时，电池图标并没有表明这一点(尽管硬件充电灯打开了)。除了那些案子我不介意更新时间。

奇怪的是，当我拔掉充电器时，图标会立即更新。我已经想出了一个更新唤醒的临时解决方案，它可能起作用，也可能不起作用，但似乎应该有一个很好的解决办法。在宏碁Aspire E5-575G-53VG上运行Ubuntu 16.04。

acpi总是显示正确的电池百分比和状态。sudo service upower restart强制upower的电池状态进行更新。

插入式充电器时upower --monitor-detail的输出：

我注意到，当充电器插上电源时，电池状态仍然是discharging。但是，/org/freedesktop/UPower/devices/line_power_ACAD正确地报告了online。任何对这个问题的帮助都是非常感谢的。我不记得在KDE上有过这个问题。

在我之前的一个项目中，我发现统一上的电源指示符确实有明显的事件驱动的延迟更新，并且它起源于UPower守护进程，而这正是该指示器用于获取电源信息的方式。这妨碍了定制脚本的使用，这些脚本试图通过UPower守护进程以一定的精度监视电池的使用情况。但是，UPower服务确实有更新/刷新该信息的调用。下面的脚本利用了dbus调用。脚本将被复制并保存为一个文件，最好保存在~/bin文件夹中。

使用非常简单：./update_battery.py <SECONDS>，其中<SECONDS>是您希望刷新信息的频率。显然，您必须记住，非常频繁的刷新会导致更高的资源使用，所以我推荐一些比较合理的东西，例如3-10秒。
