Hi, 3 days ago I got a MacBook Pro 13" as an early birthday present to replace my old 13" mbp that got stolen. On my previous MacBook pro (Late 2011) I never cared about the battery and always charged it overnight and I would get 5-6 hours which was enough and I never plugged it in during the day. With this new MacBook pro I really want to take more care of it and especially take care of the battery, I've searched through the forum and found mixed options on whether I should let my computer always plugged in (Since I really never go out with it) or charge it, let the battery drain, charge it again and so on. So thats m first question: - Should it always be plugged in or should I charge it, drain it and then charge it again. The other concern I'm having is that I downloaded an app from the Mac App Store called: Battery Doctor. and it says my battery capacity is in 99% Original Max: 5770 mAh Current Max: 5736... After only 3 days! So my other question is: - Did my battery come defective? Im really worried because I think loosing 1% of battery capacity in just 3 days is really bad, it also says I have 5 cycles... Thank you so much and I'm sorry for my english in this post, I'm 14 and English is not my main language.
