Taking the best care of my MacBook Pro battery

Hi - I wonder, while I'm using my computer, should I plug it up when I'm home even though the battery is fully charged? I've heard yes and I've hear no. Who know what's the truth of the matter. I have anew laptop and am trying to take the best care of it.

The best policy is if you are near the mains leave it plugged in, if you need the portability then run on the battery.

In this way you reduce the cycle count.

Your battery will never over charge.

You have a "smart battery." You cannot overcharge it.

One thing to avoid: calibration. Many third-party battery info sites will blindly recommend that. Apple withdrew its recommendation for calibration when they changed to "built-in" notebook batteries about 2009. That is alluded to in the article Limnos linked for you.

Having "been there; done that," I find the best thing you can do is to not obsess over your battery. The batteries that seem to give the longest service life are the ones that get used. Many that die too young were seldom used.

I try to run my 2012 MBP on battery at least once a week. I prefer to wait until the charge level is under 50 percent to connect the charger but that is not a hard rule. Its battery is now over eight years old and still has 85% of its original capacity.

In that same article, comments about operating temperature seem to focus on ambient temperature but can include the computer's internal temps. People can overheat a notebook computer in a room that is at perfect ambient temps and that can negatively affect the battery.

This Apple support document discusses how to avoid overheating:
