Battery PowerA taskbar widget for Windows 10 and 11Pro

Battery Power answers the question you actually have — how long have I got — and leaves the percentage as a footnote, because Windows already puts one in the tray. The level is a rail across the whole strip, quartered like a fuel gauge, so you can read it without reading a number, and a battery cell beside the reading carries the state the rail cannot say — charging with a bolt through it, filled in arc blue while it sits on mains, ember as it runs down, red and struck through the shell when it is nearly out, and crossed out entirely on a machine that hasn't got a battery. The charge inside it is drawn to scale, not snapped to thirds. At rest it is monochrome. Colour only arrives when something is happening or something is wrong: a charge current runs along the rail while the machine is charging, so you can tell charging from merely plugged in across a room, and the rail turns to ember and then to red as the reading gets serious. Click it for battery health, capacity against design capacity, chemistry and voltage — the figures Windows buries — and where your machine won't report one, it says so instead of inventing it.
