First of all: sorry for the last mail. I copy pasted the wrong email. Needed to resend it as I sent it with the wrong mail account to the list.
@Curtis: Thanks. The hint to the manpage and the "last_full_capacity" property did their job.

... Another issue I have is that the POWER_SUPPLY_STATUS shows 'Unknown' on AC but 'Discharging' on Battery. Do you have any idea why? My guess is that i3 uses this property to show the battery/AC state in i3status and because of the 'Unkown' value I don't get updates on the state there. The values for POWER_SUPPLY_STATUS on my laptop are: - when running on battery, it is always 'Discharging' - when running on AC: - 'Full' for 100% - 'Unknown' for 95%-99% - 'Charging' for <95% Note

You are right. I can confirm this behaviour but with different thresholds. Because of the age of the battery a FULL is never reached. The battery just has to get really low in order to come to its charging status.
I just remembered a thing and would be interested what you think.
Today only arch runs on my notebook but some time ago I was using dualboot windows, too. At that time the lenovo energy manager realized I mainly use the notebook on AC and switched the maximum battery capacity to around 70% (cannot recall the ecact value). I did not switch that back to 100% before wiping windows.
-Is it possible that's (partially) the reason for the low CHARGE_FULL value compared to the CHARGE_FULL_DESIGN value? Or to put it different: Is it possible that the lenovos' windows energy manager driver set CHARGE_FULL to a lower value and linux drivers cannot overwrite this value? -Is there a possibility to change propertys displayed in /sys/class/power_supply/BAT0 without reinstalling windows and fixing it there?
If you have links or knowledge for me, I would be really glad as I didn't find anything on my own.
Best regards,
Christian
I also get the Unknown value, but I've set the thresholds of my T530 to something lower, using TLP [ https://wiki.archlinux.org/index.php/TLP ]. I don't think the value of CHARGE_FULL related because the charging thresholds seem to be completely independent, and I've been watching mine go down slowly ever since I bough my laptop. Also, reduced capacity over time is expected for any battery. Additionally, TLP lets you change the charging thresholds arbitrarily at runtime, and that value doesn't follow. ~Matthew
