I read somewhere that should once a month let the computer discharge the battery up to 20% How true is that?

0% true.

You can leave the computer plugged in whenever convenient to do so. Neither the computer nor battery will be damaged by leaving it plugged in. Leaving it plugged in reduces the rate of accumulation of battery cycles.

As @bobthefisherman says, you can indeed leave it plugged in all the time.


People still seem to think batteries should be emptied completely before recharging etc, but the good news is, you don't. And, as the previous reply says, if you leave the machine plugged in it reduces the cycle amount, which means your battery stays healthier for longer - in some cases still running happily after 10 + years (although with slightly less autonomy).
