Hi folks.

I'm thinking of playing few old games (Civilisation V, Warcraft, etc.) on my Macbook Pro 2013. Until now I have completely avoided gaming on it for fear of ruining the battery.

Now, I'm thinking of having it plugged in during gaming, so it draws AC power instead of battery while I play games. Will this protect the battery from adverse effects? Or regardless of plugged in or not, the battery will be adversely impacted from gaming?

Any help/insight will be greatly appreciated. Thank.

It won't be impacted if you draw AC power from cord instead of battery, you can unplug the battery if you like but be careful with the cable then so you don't unplug it. Battery has certain lifespan which is measured by how many times you charged it. You can charge up to 1000 times let's say until it starts to perform worse than usual.

I don't know where you heard that, gaming on your Macbook doesn't kill the battery...

Battery damage occurs if you mistreat the charging cycle. Plugging a charger in randomly rather than when the battery is almost empty will certainly be far more taxing on its longevity. Equally, not letting it fully charge before use again is also not ideal.

Gaming doesn't kill batteries...not understanding them does

It's not good practice to let a Lithium battery discharge until it is almost empty. Keeping it somewhere between 25% and 75% charge level will give the maximum life. Letting it charge fully is not the best procedure as it is likely to lead to greater temperatures, which is the real killer.

That was true with NiCd but is no longer true with Li-Ion because their discharge is closely regulated by on-board circuits.

Using the right type of charger and reducing the charge cycles you put through the battery are the key...By charging it at 25% you are essentially increasing the amount of charges over a longer period of time and that will hurt the battery.

Furthermore using the correct voltage rather than quick chargers or low voltage stuff like car chargers etc is also a big factor.

The biggest one though is temperatures...not exposing the battery to high temps is really really key when guarding it's lifespan....and guess what, charging it really heats it up...so avoid charging it often...how? By letting it almost empty and then charging it to full or almost full...

Similar to a mechanical device that wears out faster with heavy use, the depth of discharge (DoD) determines the cycle count of the battery. The smaller the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine. There is no memory and the battery does not need periodic full discharge cycles to prolong life. The exception may be a periodic calibration of the fuel gauge on a smart battery or intelligent device.
