Gaming on my MBP - will it kill the battery?
So, this might sound strange to some people, I apologise for that. I had always wanted to own a Macbook and after saving up for a while I finally got myself a Macbook Pro Retina 2013 (Late). I baby it around and I'm an extremely happy user so far.
I intend to use it easily for another 2/3 years. I used to be an avid gamer before but my previous laptop's (Lenovo) battery stopped holding charge at all after a year - I used to play games on it extensively. I do not like the idea of having to open my Macbook and changing its battery. So, now I don't play any games at all. But recently I read somewhere that using your Macbook while plugged in draws power from the adapter and there is no battery usage.
I want to know the validity of this. Is this true? I would like to play few old games like Civilisation 5, Warcraft, etc. on my MBP while keeping it plugged in. Will this keep the battery safe from any adverse effects? This is a bit long and I'm sorry for that. But I would really appreciate any insight on this matter.
Thanks so much!
