The author reports that temporarily setting TLP charge thresholds to 100%, restarting, and charging for almost a day corrected the observed calibration issue. ### Source excerpt My brand new Lenovo Thinkpad is a beast and is supposed to give up to 8hrs of battery backup. But there was a weird problem. As soon as the battery remaining reached 30%, it used to drop to 6% in a second. When I looked up on google, I found out that I was not the only one facing this problem. Most of them suggested that my battery was shot and that I had to buy a new one. This is highly improbable as it is brand new. I wanted to give fixing it a try before contacting customer care. And I was successful! Before - See the battery percentage drop from 30% to 6% For some reason, I suspected that it was somehow TLP's fault. TLP is the best power management utility for Thinkpad in Linux. It allows you to set max charging threshold so that you will be able to connect your laptop to the plug point without worrying about over charging (among many other features it provides). I felt that it is because of this, battery calibration was getting screwed up. So I set the maximum threshold to 100%. Open /etc/default/tlp and set following variables. START_CHARGE_THRESH_BAT0=100 STOP_CHARGE_THRESH_BAT0=100 Then I restarted my laptop to bring this to effect. As the calibration was already offset by a great extent, the only way to fix it was to keep it charged for a long time. I kept it charging for almost a day. After - Fixed! Then to test it I kept discharging it. And to my surprise, it didn't drop from 30% to 6% this time!! So the problem was with calibration and not because the battery is broken. If you face this problem, you can try this solution once before you spend $$$ on buying a new battery. Now that I have changed the battery threshold back to 85%, if this problem occurs again, all I have to do is follow the above steps.
