As I use my 3DS quite a lot, and it is nearly always turned on (albeit on idle) I am interested to know how / when I should charge the 3DS in order to get the most out of the battery life. I've heard before that you should completely drain the battery before charging again, then I've also heard that fully draining will break the battery, then I've also heard that it doesn't matter and that the battery will last exactly the same amount of time whatever you do with it. One thing I have noticed about Nintendo products (might be the same with every electric device though) is that when you charge them, even if they are turned on, once it has reached it's maximum it will stop charging, even though the plug is still in the system. However if you unplug it and plug it back in again the charging light will show for another 5 minutes before turning off again (this time reduces with each unplug / plug in). Is this a bad thing to do? I remember doing it with my DS Lite when I was younger until the light only showed for half a second. One last thing, I know changing back-light settings etc. will affect how long the battery lasts on each charge, but does this also affect the battery's overall life? Thanks, Wizzerzak.
