 $ sysctl -d hw.acpi.battery.time
 hw.acpi.battery.time: remaining time in minutes
 
 Why is it impossible or improper to compute and show battery's remaining
 time ? Because the machine is on on-line power supply ?
 
 The battery's state, that is, its remaining time, is still valid and of
 interest to user at any machine state (load, etc), regardless of power supply
 being on-line or off-line.
 
 I want to know WHAT IF, at any time (without or with consideration of current
 machine state (load, etc) in the computation of battery remaining time),
 I disconnected the on-line power supply, could I expect to happen to my
 machine with regard to expected length-of-time availability of battery power
 supply.
 
 If you think that the battery's "percent capacity remaining" is enough, then
 you are mistaken.
 hw.acpi.battery.life: percent capacity remaining
 
 The battery's "percent capacity remaining" is misleading because its max level
 is degrading over time (the 100% of a new battery is not the same 100% after
 a year or so of random discharging and charging). They just do not tell me
 how much estimated run time I would have as I explained above.
 
 This is what Linux shows about my battery state:
 
 $ cat /proc/acpi/battery/BAT0/info
 present:                 yes
 design capacity:         56160 mWh
 last full capacity:      38720 mWh
 battery technology:      rechargeable
 design voltage:          10800 mV
 design capacity warning: 1936 mWh
 design capacity low:     200 mWh
 capacity granularity 1:  1 mWh
 capacity granularity 2:  1 mWh
 model number:            COMPATIBLE
 serial number:            2413
 battery type:            LION
 OEM info:                BATSZ
 
 $ cat /proc/acpi/battery/BAT0/state
 present:                 yes
 capacity state:          ok
 charging state:          charged
 present rate:            0 mW
 remaining capacity:      38720 mWh
 present voltage:         12405 mV
 
 These are the original and degraded capacity values of 100% I am talking
 about:
 ...
 design capacity:         56160 mWh
 last full capacity:      38720 mWh
 ...
 remaining capacity:      38720 mWh
 ...
 
 So, please compute this
 hw.acpi.battery.time: remaining time in minutes
 and make it available at any time, and at any state of the machine.
 There is a good use for this data.

 Im most systems, ACPI does not return the battery lifetime when on AC
 power. The actual remaining time is calculated by the EC BIOS and is
 calculated mostly be taking the discharge rate in mW and the current
 capacity in mWh. As far as I know, no OS attempts to calculate the time. It
 is simply read from the the EC via ACPI. When plugged in to AC, the
 discharge rate is 0, making the calculation undefined (division by zero).
 Even the remaining battery time reported by ACPI is, at best, a very rough
 guess as discharge rate can vary dramatically depending on system load.
 
 On FreeBSD you can see detailed information on batteries with the
 acpiconf(8) command. "acpiconf -i N" where 'N' is the battery number; 0 if
 only one battery is present.
 My system on battery:
 esign capacity:    50540 mWh
 Last full capacity:    46660 mWh
 Technology:        secondary (rechargeable)
 Design voltage:        10800 mV
 Capacity (warn):    2333 mWh
 Capacity (low):        200 mWh
 Low/warn granularity:    1 mWh
 Warn/full granularity:    1 mWh
 Model number:        42T4795
 Serial number:         2654
 Type:            LION
 OEM info:        SONY

 Remaining capacity:    96%
 Remaining time:        2:12
 Present rate:        20460 mW
 Present voltage:    11652 mV
 
 And after plugging in to AC:
 Design capacity:    50540 mWh
 Last full capacity:    46660 mWh
 Technology:        secondary (rechargeable)
 Design voltage:        10800 mV
 Capacity (warn):    2333 mWh
 Capacity (low):        200 mWh
 Low/warn granularity:    1 mWh
 Warn/full granularity:    1 mWh
 Model number:        42T4795
 Serial number:         2654
 Type:            LION
 OEM info:        SONY
 State:            high
 Remaining capacity:    96%
 Remaining time:        unknown
 Present rate:        0 mW
 Present voltage:    11648 mV
 
 Looking at the raw sysctl when on battery shows hw.acpi.battery.time: -1.
 This is normal. I don't see that ACPI
