From the developer:
Battery Spy measures the time it takes for your battery to empty. The application monitors your battery uptime in a simple, accurate, and elegant way. The counter starts the moment you unplug your AC adapter. Regardless of whether you unplug it at 100% or 65%, Battery Spy will count down the time it takes for your battery to empty (or until you plug in your AC adapter again).
