I was messing around with Decky and made a small plugin to check battery health. Might be useful for someone else.

It’s very simple just displays health percentage (based on full vs design capacity),

No fancy features yet I mainly made it for myself to quickly check on things inside Gaming Mode.

Planning to maybe add cycle count, temp, or charge rate later if I can find reliable data for those.

Let me know if anything breaks or if there’s a feature you’d want!

Also… I did notice the KDE battery health menu after I started working on this
