Battery Remaining Time Not Shown in KDE after Upgrade to Kubuntu 23.10

After upgrading to Kubuntu 23.10, you may notice that the battery remaining time is no longer displayed in the KDE system tray. This can be frustrating, especially if you rely on this information to manage your laptop's battery usage. Fortunately, there are a few steps you can take to resolve this issue.

Step 1: Check Power Management Settings

The first thing you should do is check your power management settings to ensure that the battery remaining time is enabled. Here's how:

1. Click on the KDE menu icon in the bottom left corner of your screen.
2. Navigate to System Settings and click on Power Management.
3. In the Power Management window, click on the Battery icon in the left sidebar.
4. Make sure the "Show remaining battery time" option is enabled.

If this option is already enabled, proceed to the next step.

Step 2: Install Battery Monitoring Tools

If the battery remaining time is still not showing, it's possible that the necessary tools are not installed on your system. You can install them using the following steps:

1. Open a terminal by pressing Ctrl + Alt + T on your keyboard.
2. Type the following command and press Enter to install the necessary tools:

Enter your password when prompted and wait for the installation to complete.

Step 3: Restart KDE Plasma

If the battery remaining time is still not showing after installing the necessary tools, try restarting the KDE Plasma desktop. Here's how:

1. Press Alt + F2 on your keyboard to open the Run Command dialog.
2. Type kquitapp5 plasmashell and press Enter.
3. Wait for the desktop to restart.

Check if the battery remaining time is now displayed in the system tray. If not, proceed to the next step.

Step 4: Create a Custom Battery Widget

If none of the previous steps have resolved the issue, you can try creating a custom battery widget to display the remaining time. Here's how:

1. Right-click on an empty space in the system tray and select "Add Widgets" from the context menu.
2. In the Add Widgets window, search for "Battery" and drag the Battery widget to the desired location in the system tray.
3. Right-click on the Battery widget and select "Configure Battery..." from the context menu.
4. In the Battery Configuration window, make sure the "Show remaining time" option is enabled.
5. Click Apply to save the changes.

The custom battery widget should now display the remaining time in the system tray. If you prefer using the default battery icon, you can remove the original battery widget by right-clicking on it and selecting "Remove" from the context menu.

By following these steps, you should be able to resolve the issue of the battery remaining time not being shown in KDE after upgrading to Kubuntu 23.10. If you continue to experience problems, it may be worth seeking further assistance from the KDE community or your computer manufacturer.
