Hi, please could I get some advice on how to keep my battery healthy? I've heard it's best to keep it between 40 and 70% (or something like that) and never let it drain to 0 (maybe once a month?), but I've also heard that if you keep it plugged in then that will prolong the battery life because you will be taking power from the power adapter and not the battery= less cycle counts. I'm a uni student so will definitely be using the battery, but is it best to keep it plugged in where I can? I know you can't keep the batteries running forever and it would be a waste of time to baby it too much, but I'd like to keep it running as well as I can. I seem to have ruined my iPhone 6's battery (it barely holds a charge and often dies at high percentages), and my current MBP is a 2010 so the battery is past it now anyway. I'm getting my new MBP (nTB 13 inch) next week so I'd like to get into good habits from the start, just confused on what the best thing to do for it is. And any other tips/tricks/things NOT to do. Also, can I use it straight out the box?
