Q: How should I charge my 2015 rMBP?
Hello everyone
I just received my 2015 rMBP 13 inch model and I'm very happy with it. It is very fast, Force Touch is amazing and I used it on battery and it really lasted ages. Now I want to keep the battery in healthy state. How can I do this?
What I read on Apple community and on various sites is the following: Use the rMBP as much on charger as you can (to preserve some charge cycles) and discharge (to 40% or so, not too low) every week or so. As I'm a student who uses this laptop for note taking, I will surely be discharging it and using it on battery a few times a week.
What answer I got from chatting with an Apple coworker: you should charge to 100% and then discharge to 30 ish % and then recharge and repeat. This is because there is a memory effect happening (according to that person). I think this person has wrong info, or is he right?
What I'm planning to do: When I'm at home, I'm going to use it on charger and at least once a week I'll use it on battery (note taking or whatever). Is this a good rule of thumb?
And another question: When it's on the charger, is it bad to just put it in standby (closing the lid) or should I turn it completely off every time? And is it bad to keep it on the charger while it's off?
TL;DR: Charger all the time (with discharge every now and then) or Charge 'n discharge all the time?
While on charger: sleep or fully off?
When the laptop is off: should I remove the charger?
Thanks in advance
