Regarding battery wear on laptops

After having used the laptop for 4 months. I opened up the battery info to check how much of life the battery has lost.

The results were much better than what I expected :


Before calibration it showed 0.3% wear rate.


After calibration battery wear was completely gone.

The calibration is done by fully discharging and charging the battery 2 consecutive times.

I kept the charger plugged all the time whenever I put my laptop on my desk and I took my laptop very often in weekends. People say that using the charger after full charge can severely cut the battery life, but from these results, at least I won’t worry about it again.
