How can I see the battery status of my Logitech wireless mouse?

Is there a way to monitor the mouse's battery status in Kubuntu? I have a Logitech Wireless Mouse M510 and in Windows I can use the default software (from official site) to monitor battery status and do other things like editing some mouse buttons etc.

Is there any software to do same thing or just monitoring battery status (applets, widgets, software etc.)?

From the CLI, UPower can do this:

$ upower --dump Device: /org/freedesktop/UPower/devices/mouse_0000o0000o0000x0000 native-path: /sys/devices/pci0000:00/0000:00:14.0/usb3/3-9/3-9.4/3-9.4:1.2/0000:0000:0000.0000/0000:0000:0000.0000 vendor: Logitech, Inc. model: Anywhere MX serial: 00000000 power supply: no updated: Sun 10 Jul 2016 04:47:36 AM EDT (84 seconds ago) has history: yes has statistics: no mouse present: yes rechargeable: yes state: discharging warning-level: none percentage: 95% icon-name: 'battery-full-symbolic' [...] 

From the GUI, mate-power-statistics (from the MATE Power Manager project) or gnome-power-statistics (from the GNOME Power Manager project) can do this.

Using the Solaar program as described in this answer, you can obtain the battery status.

The M510 is a HID++ 1.0 device judging from the register dump at the Solaar repository. The HID++ 2.0 document that include Battery Unified Level Status as linked by gertvdijk are irrelevant here.

As noted on , the "07" register shows the battery status. If you want to learn more about the technical side, you can read my article about reverse engineering the protocol.

You can go to your power settings. There you will hopefully have the battery left of any device that runs on batteries.

In my distro (Mint) I can see the battery remaining of my laptop and my mouse by clicking in the power icon at the status bar (bottom-right).

I can also go to power management, and there is a "Batteries" tab, and there it is too.

I don't know if this is available in all distros, but it is so easy to check that there's no harm in giving it a try.

Search "power" in the GUI and pull up power statistics. Click mouse on the left, the default will be the laptop battery. Note this will not work if the battery is already dead (as I just learned).
