There was a pretty good study done on this specific question done here. Also, it's important to note that Apple's stated battery life is based upon very light workload tests. http://www.anandtech.com/show/7113/2013-macbook-air-core-i5-4250u-vs-core-i7-4650u/4 Key take aways Idle/light workload battery time is nearly the same Medium and heavy workloads ...

Everytime we unplug the power, Mac will start to discharge the battery. In this manner, the battery lifespan will shorten. I think the answer would be to leave the charger on, whenever possible, as the charger actually stop charging the battery once it is full.

You’ll see “low signal” when you are using service in a poor reception area. When the phone needs to search for a signal all the time it uses more battery life. We normally see this on Home & Lock Screen and Personal Hotspot.

I can speak from experience that the battery from by 2011 MBP 13' died (like only 10% of designed capacity left) after 56 cycles. It met a precipitous decline after a certain point. You may want you weigh your risk on the cost of replacing the battery.

In my experience one of the worst things for a battery is to leave it plugged in and not cycle it. After doing this for a few months most batteries seem to become useless, sometimes not even keeping a charge for 5 minutes.
