power.battery

power.battery readonly

The power.battery property gets the current battery usage as a table. If no battery is present, the property returns nil.

The table provides the following fields :

charging : indicates if the battery is charging or not.
percent : indicates the battery left, in percent.
lifetime : indicates the battery lifetime in seconds or nil if the system cannot calculate it.
saver : indicates if the battery saver is currently in use.

Example

if power.battery then
  print("Battery is "..(power.battery.charging and "charging" or "not charging"))
  print(power.battery.percent.."% left")
  print(power.battery.lifetime and math.floor(power.battery.lifetime/3600).."h remaining" or "Battery lifetime not available")
  print(power.battery.saver and "Battery saver is in use" or "Battery saver is not in use")
else
  print("This computer don't have a battery")
