When I connect a wireless controller to my desktop (a DualShock 4 v2, in my case), the Power Management system tray entry becomes Power and Battery, and shows the controller’s battery level. I have this icon set to ‘Shown when relevant,’ however it seems to stay ‘irrelevant’ despite a battery device being connected.
Would it be possible to make Power and Battery become relevant when a device whose battery level it can display is connected?
Hey, I was actually for this as well (but with a dualsense in my case 
) and then thought it would be even more comfortable if I would simply see the battery level of the controller directly on the panel instead of having to click on the Power and Battery icon.
Since I couldn’t find any widget that does that I decided to take the opportunity and learn how to build one.
Have a look at BatteryWatch, it allows you to:
See battery percentages for all your Bluetooth and wireless devices in the tray area
Supports game controllers, mice, keyboards, headphones, etc. Pretty much everything that’s Bluetooth or wireless and reports the battery status
The tray icon automatically hides itself when nothing’s connected, so it doesn’t take up empty space
Click the icon and you get a nice list of everything with their battery levels
Disconnect Bluetooth devices straight from the widget
Hide specific devices from the tray area if you don’t want them showing up there
I would love for some user testing since I could only test it on devices I had at home - you can find it in the KDE Store.
Hope you find it useful (like and rate if you do!) and would love to hear your feedback!
That is so cool! Thank you for taking the time to make this.
My pleasure! It was fun
Glad you like it!
