I always play computer games on my laptop without disconnecting the charger. is this act going have any effect on my battery life?
I'm on the opposite side.Well, it could put a lot of extra heat to the battery from both a drain and a charge simultaneously. It may even depend on how demanding the game is. On a newer game that is visually demanding, it could actually not charge the battery.
Overall, I wouldn't suggest it.
I'm on the opposite side.
If you have your battery at 100% there's no charging, just the maintaining charge and the power comes directly from the PSU.
On the other side playing almost on battery put it on very high stress and high current discharge rate which could shorten a lot the lifespan of batteries or kill the battery.
For high energy draw tasks PSU is the best option when you have AC available.
Charge the battery to 100% when you have to play games. When it's at 100% you can play games.
Some fans (cooling pad could be ok) can be useful to keep chassis temp lower, to limit any battery wear caused by the heat generated by the system.
To limit battery wear,which comes naturally because li ion battery have natural wear even with no use, try to do some discharge cycles sometimes, one time at week or month.
You don't need to fully discharge it (it's another source of stress and wear), 40-50% it's ok.
These information I'm giving can be found in the web, on the battery university website and they are proved to be real, based on my real personal experience on many devices in the past decade.
I just don't get the people who insist on keeping their battery between 40-80% (like mentioned in the article on the main page about this). Sacrificing battery runtime to preserve overall battery longevity seems a bit bizarre, since even in a couple years the odds of losing 60% charge capacity is slim even if you do frequently top or drain then charge.
Yes, you will lose some overall capacity, but enough to offset the limited life you're forcing yourself with by sticking to 40-80%? Not likely.....
