NAME

       battery-stats - collected battery statistics

DESCRIPTION

       The battery-stats contains statistics about battery charge over time, as collected by the battery-stats-collector (8) daemon.

FORMAT

       Each line in the file represents one sample and is of the form:
						  <seconds> <charge%> <powermode> <UTC-date> <UTC-time>
       separated by spaces and terminated by a newline.

       Where:

       seconds
	      is the number of seconds since 1st Jan 1970 00:00:00 UTC

       charge%
	      is the battery charge a number between 0 and 100

       powermode
	      indicates the power mode:
		       0 A/C off
		       1 On battery
		       2 On backup power

       UTC-date
	      a human-readable date in the format YYYY/MM/DD. Note that this is in UTC, not the local or system timezone.

       UTC-time
	      a human-readable time in the format HH:MM:SS (using a 24-hour clock). Note that this is in UTC, not the local or system timezone.

       minutes-left
	      is  the  BIOS estimate of how many minutes of running time the battery would provide.  This may be unreliable, depending on the BIOS
	      through which it was collected.

EXAMPLE

       A battery under charge might result in the following samples:
	      1032651245 27 1 2002/09/21 23:34:05 94
	      1032651275 28 1 2002/09/21 23:34:35 97
	      1032651305 29 1 2002/09/21 23:35:05 100
	      1032651335 30 1 2002/09/21 23:35:35 103
	      1032651365 30 1 2002/09/21 23:36:05 106

FILES

       The default set-up is to save battery statistics in /var/log and rotate the logs weekly, which results in this set of files:
       /var/log/battery-stats - current (most recent) statistics
       /var/log/battery-stats.[0-9]+ - less recent statistics
       /var/log/battery-stats.[0-9]+.gz - ancient statistics
