I use my MacBook Air for gaming. I know the charging cycle hurts it lifespan and gaming means you have to charge it more. If I play a game while on the power adapter, will that affect the battery life, or battery lifespan in any negative way?

    You can keep a Mac portable on the power adapter while it is used...the charging circuitry stops charging and goes to line-power operation when the battery is fully charged.  If insufficient power is available from the charger, the Mac will supplement the power needed by using some from the battery.  But doing so does not adversely affect the battery.

    I think not,

    You do not use the battery ...

    What do you mean line power operation? And just to be clear it doesn't affect battery negatively?

    Using it while plugged in will decrease the number of charge cycles it has to go through.

     

    It's a good thing (provided that you don't leave it plugged in all the time)

    Would using it for about 1-2 hours plugged in every day count as all the time

    As long as you use it on battery for a few hours a month you will be fine. Stop worrying and enjoy it.

    Line-power operation means the MacBook Air is connected to the power line via the charger.  If the battery is fully charged, as indicated by the MagSafe connector showing the green LED, then you are operating on the power line and not the battery.  If the LED shows amber then you are either charging the battery or using some battery power in addition to the line power.

     

    That is not harmful to the battery.

     

    Taking the MacBook Air off the power line monthly and using the battery, maybe down to 50% charge level, is good practice as it exercises the battery.
