Macbook pro 13 plugged in all the time.

Hi, I am sure this has been asked before but I cannot find any consensus on whether it is bad for battery lifespan to leave my MBP 13 plugged in all the time or not.

Thanks

you should probably ask on a battery specialists forum

Once or twice a week, UNplug it from the charger.
Let the battery run down to about 30-40% of charge.
Then plug it back in.

It won't hurt a thing to leave it plugged in all the time.

Here is some battery info straight from Apple.

Apple used to have some info on there about exercising the battery occasionally, but they no longer do.

Thanks, so I belive there is no harm unless you run on battery once or twice a week.

If it is truly plugged in all the time then it seems you don't need the battery so it doesn't matter. My early 2013 MBP has been plugged in for 99% of its life and the battery still works ok when I take it offsite to use.

Well to be honest I keep it plugged when I'm on my desk or at home then unplug it when I go to sleep.

I unplug mine every time I put it to sleep (a few times a day and overnight) and only plug it in when using it. Who knows how these batteries really age or degrade 😳

Do you use it in battery mode from time to time or only plugged in?

Very rarely in battery mode and no more than two or three hours at a time. Not due to battery life but due to my needs.

As a Windows Sys Admin I've seen a few laptops that had dead batteries with users who only used the docking station at work and home. Then after a year of two when they needed to use their laptop on battery, found it didn't work/hold a charge.
Funny thing is I never had a MacBook have that issue. I think maybe Apple uses higher quality parts than Windows vendors....

Always discharge your battery to about 15% at least once a month. I've done that with all my Apple notebooks and never had an issue with a single battery. My 2010 MBP still holds a 6-7 hour charge.
