From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

command: sudo tlp-stat -b

output:

TLP 1.6.1 --------------------------------------------

+++ Battery Care

Plugin: generic

Supported features: none available

+++ Battery Status: BAT0

/sys/class/power_supply/BAT0/manufacturer = DP

/sys/class/power_supply/BAT0/model_name = bq20z451

/sys/class/power_supply/BAT0/cycle_count = 666

/sys/class/power_supply/BAT0/charge_full_design = 6330 [mAh]

/sys/class/power_supply/BAT0/charge_full = 5043 [mAh]

/sys/class/power_supply/BAT0/charge_now = 4936 [mAh]

/sys/class/power_supply/BAT0/current_now = 0 [mA]

/sys/class/power_supply/BAT0/status = Full

/sys/class/power_supply/BAT0/charge_control_start_threshold = (not available)

/sys/class/power_supply/BAT0/charge_control_end_threshold = (not available)

Charge = 97.9 [%]

Capacity = 79.7 [%]

my take:

this is an apple battery, meaning this command won't load it up to a threshold I choose (not available)

charged currently at 97.9%, even if the gui says it's 100%

capacity is 79.7%, what for me is a very high value, considering this is a 10 year old notebook (maybe it hasn't been used much?)

your take?

The best way would in fact be testing it with an electronic load that applies a precise and well known load to the battery and integrates capacity until a matching shutoff condition is reached.

However, the majority of people do not happen to have access to such an instrument, so I'd say your suggestion is a close approximation of the best way, which could be augmented by adding simple measurements, which can be done by most people at home for a reasonable, quantifiable judgment.
