Q: Prolonging MacBook Pro 15" (Mid-2014) Battery Life & Overall Health
Good day, folks.
I purchased a used MBP yesterday. Specs:
Model Name: MacBook Pro
Model Identifier: MacBookPro11,2
Processor Name: Intel Core i7
Processor Speed: 2,2 GHz
Number of Processors: 1
Total Number of Cores: 4
L2 Cache (per Core): 256 KB
L3 Cache: 6 MB
Memory: 16 GB
Cycles: 130
Aside from a few nicks and scratches here and there from general wear and tear, the machine seems to be in a fantastic condition, and beyond that, having recovered pretty much my exact old setup via Time Machine, is a blisteringly fast improvement upon my Mid-2009 Core Duo 2 MBP.
Now I want some advise to make sure this machine lasts me another six years (wishful thinking? Well the last one did, but its GPU is beginning to fail...), so questions:
1) Leave the machine plugged in and on charge over night?
2) Drain all the way down and then recharge fully? I've been informed by a trusted friend that it's a good idea to keep the battery's charge above 20% if and whenever at all possible.
3) Let it fall asleep on its own, or put it to sleep manually? I prefer the latter, at this stage.
4) I use a USB Receiver for Bluetooth Mouse + Keyboard, and on top of that an Eternal Display connected via Thunderbolt (can use HDMI too, at this point, just still have to old VGA -> Firebolt Adapter); should I unplug these when the machine is put to sleep? It appears they draw a fair amount of power (I did a test last night to see how long the machine lasts on battery when connected to these; doing so now, and it's going strong).
I'll probly have a few more questions based on answers to the above, but thank you all in advance for any thoughts/input.
MacBook Pro with Retina display, OS X Yosemite (10.10.5)
