Some people recommend to keep the ac charger always on ,so that battery charge count remain less,
Where as some people says to disconnect the charger after 100% and then use it till 20% or less and then charge it again till 100%.
So there is little confusing regarding these matter.

The real answer is don't sweat it. Modern laptop batteries are very sophisticated devices and take care of themselves. Until they don't and you have very little control over it. You expect to replace it. It will not last forever. 

 

Now, specifically, you ask whether it is better to keep it plugged in all the time or run it down to 20% and then recharge to 100%. These are not mutually exclusive. If you use your laptop largely as a desktop, it is safe and OK to keep the battery in and run it on the charger all the time. You might get a little longer battery life if you remove the battery and store it while it is used as a desktop replacement because the cycle counter will likely pick up fewer cycles. But it will not make enough difference to be worth the trouble of removing and storing the battery and putting it back in if you want to go mobile. 

 

When it is mobile you are right. Don't let it drop below 20%. That is the hardest thing on a battery. But it is safe to run it down to 20%, charge it back up to 60% and go again. That is sometimes what you have to do on an airport layover, for example. Lithium ion batteries have no memory effect. If you can, charge it to 100% before using again, but it is not like 25 years ago when failing to do that would cripple the battery. 

 

Hope this helps.
