Wattage is a graphical application for inspecting the health and status of power devices connected to a Linux system. It presents battery and energy information through a GTK interface, keeping common status information together in an accessible form.
The application uses UPower over D-Bus to obtain device information. This provides a common interface for laptop batteries, AC supplies and other supported power devices rather than tying the application to a particular hardware interface.
Historical information can also be examined to see how battery and power measurements have changed over time.
This is free and open source software.
Key Features
- Display information reported by UPower for recognized power devices.
- Monitor laptop batteries and other supported battery-powered hardware.
- Show information about AC power sources.
- Recognize additional UPower devices such as supported headsets and styluses.
- Display battery capacity and current charging or discharging status.
- Show battery health information useful for assessing long-term degradation.
- Display voltage and available energy-related measurements.
- Show model and manufacturer information supplied for a device.
- Support systems containing multiple batteries or other power sources.
- Present battery history in a list for examining earlier readings.
- Provide a graphical history view for visualizing changes over time.
- Use D-Bus and UPower as its hardware abstraction layer.
- Use a GTK interface designed to integrate with Linux desktops.
- Provide application preferences for controlling its presentation and behaviour.
- Update displayed information as UPower reports changes in devices and their state.
