Q: can i leave my 2015 macbook pro plugged in all the time?

I was wondering leaving it plugged in all the time will reduce my battery life? I see different answers which make me confused. I bought my computer in September 2015 and my battery cycle is currently 110.

 

Any suggestions?

 

Thank you.

    Two golden rules regarding MBPs and their batteries.

     

    If you use your MBP connected to the charger all the time, at least once per month, use it under battery power to about the 40% charge level before recharging.  Lithium ion batteries need periodic exercise for a long useful life.

     

    Do not drain the battery to the point where it turns off.  Avoid deep discharges in general, below the 20% charge level.  These will shorten the useful life of the battery.
