The command breaks down into these parts:

• upower: The base command for power management
• -i: Flag for “information”
• /org/freedesktop/UPower/devices/battery_BAT0: The system path to your primary battery

When you run this command, you’ll see several key pieces of information:

Power Supply Details

• native-path: Physical location of the battery in your system
• vendor: Manufacturer of your battery
• model: Battery model number
• serial: Battery serial number
• technology: Battery type (Li-ion, Li-poly, etc.)

Current Status

• state: Current battery state (charging, discharging, fully-charged)
• percentage: Current charge level
• capacity: Health of battery compared to its original capacity
• voltage: Current voltage level
• time to empty/full: Estimated time until battery depletes/charges

Historical Data

• energy-rate: Current power consumption rate
• energy: Current energy level
• energy-full: Maximum energy when fully charged
• energy-full-design: Factory-designed maximum energy
