DRAFT - Linux Battery monitoring tools
This is my offline reminder about tools for checking battery state.
Main CLI Tools
powertop: This one is similar tohtop, allowing monitoring in real time consumption / battery dischargeupower: Gives you battery information + battery “screenshot”acpi(Advanced Configuration and Power Interface):powerstat: Monitor your computer for a few minutes before returing- Battop
Usage
upower
uppower -e lists the different battery files.
For instance, I get:
/org/freedesktop/UPower/devices/line_power_AC0
/org/freedesktop/UPower/devices/battery_BAT0
/org/freedesktop/UPower/devices/DisplayDevice
Next, for each of these paths, I can request information about using uppower -i <path>
For instance, upower -i /org/freedesktop/UPower/devices/battery_BAT0 returns:

acpi
acpi -i
When Charging and almost full:
Battery 0: Charging, 99%, 00:07:54 until charged
Battery 0: design capacity 4000 mAh, last full capacity 3485 mAh = 87%
After disconnecting the charging cable:
Battery 0: Discharging, 99%, 04:24:54 remaining
Battery 0: design capacity 4000 mAh, last full capacity 3485 mAh = 87%
After a few minutes:
Battery 0: Discharging, 92%, 05:35:16 remaining
Battery 0: design capacity 4000 mAh, last full capacity 3485 mAh = 87%
To get more detailed information, acpi -V:
Battery 0: Discharging, 97%, 03:42:49 remaining
Battery 0: design capacity 4000 mAh, last full capacity 3485 mAh = 87%
Adapter 0: off-line
Thermal 0: ok, 53.0 degrees C
Thermal 0: trip point 0 switches to mode critical at temperature 103.0 degrees C
Cooling 0: Processor 0 of 0
Cooling 1: B0D4 no state information available
Cooling 2: intel_powerclamp no state information available
Cooling 3: x86_pkg_temp no state information available
Cooling 4: Processor 0 of 0
Cooling 5: INT3400 Thermal no state information available
Cooling 6: Processor 0 of 0
Cooling 7: pch_skylake no state information available
Cooling 8: iwlwifi 0 of 20
Cooling 9: iwlwifi_1 no state information available
Cooling 10: TCC Offset 2 of 63
Cooling 11: Processor 0 of 0
Cooling 12: SEN1 no state information available
As you can see, it is detailed but with many “no state information available” …
Powerstat
powerstat starts by collecting data during 300 seconds (5 minutes), and then gives you the power consumption every 10 seconds.
Running for 300.0 seconds (30 samples at 10.0 second intervals).
Power measurements will start in 180 seconds time.
