    When I want to use my DS the next day a lot, I like to fully drain the battery, then fully charge it over night.
    To drain the battery I usually just leave it playing movies with the volume at 400%, I figure it's the most taxing thing I could make it do.

    But, I was wondering if someone could make an application that uses all the DS's resources at once? I remember reading that wifi drains the batter a bit quicker too..
    is this even possible?

    Doesn't the DS contain a Lithium Ion battery? Aren't those supposed to last longer and better through randomly timed, short and long charges as opposed to the old batteries that suffered from the dreaded "memory effect" if they weren't "cycled" properly?

    May be wrong here, but I know the former is the case with my new mobile.

    I'm sure both the ipod and DS manuals recommended fully draining, then fully charging..?

    Only Lithium Polymer batteries dont have memory effects every other does.

    Wouldn't fully draining it decrease the life span of the battery? Or perhaps speed up the decrease?

    Also, Wi-Fi with Animal Crossing: Wild World is a major battery hog.

    I heard lot's of opinions about that and users that drain battery to full, have better battery lifes, sad but true .

    Interesting........ Maybe someone in the know can clear this up once and for all

    Lithium Ion batteries don't have memory either. Most people perceive their natural lose of charge to be memory loss, but you'll get the exact same effect if you leave the battery on the shelf and don't use it.

    I'm pretty sure my iPOD manual said that the battery will last longest with normal usage patterns. Occasionally draining it fully, but usually recharging it when it's about 3/4 depleted. Not sure what the DS says, but I think they both use Lithium Ion batteries and therefore should be fully drained occasionally, but not regularly.

    I'm not a battery expert so I could be wrong, but that's what I've read.

    From personal experience, a DS or iPod or anything using an internal rechargable battery should be fully drained before usage. Reason being if the battery is not fully used and then charged it will only charge to a certain level before stopping. The level being the level of charge that the battery was at out of the box.

    My original DS had an issue with battery life caused by my wanting to fully charge it out of the box. It needs to be used until death the first time around and then fully charged to allow the battery to have a longer life.

    My understanding of Lithium Ion batteries is that they do not have "memory" like older batteries. Most of what I know I learned from information concerning my iPod. The following information is from Apple's website (http://www.apple.com/batteries/)

    "Lithium-ion batteries pack in a higher power density than nickel-based batteries. This gives you a longer battery life in a lighter package, as lithium is the lightest metal. You can also recharge a lithium-ion battery whenever convenient, without the full charge or discharge cycle necessary to keep nickel-based batteries at peak performance. (Over time, crystals build up in nickel-based batteries and prevent you from charging them completely, necessitating an inconvenient full discharge.)"

    "For proper maintenance of a lithium-based battery, it’s important to keep the electrons in it moving occasionally. Be sure to go through at least one charge cycle per month."

    "A charge cycle means using all of the battery’s power, but that doesn’t necessarily mean a single charge. For instance, you could listen to your iPod for a few hours one day, using half its power, and then recharge it fully. If you did the same thing the next day, it would count as one charge cycle, not two, so you may take several days to complete a cycle."

    It is the charge cycles that keep the battery working correctly. It doesn't matter if you do it all at once or a little here and there. Related to this, it is my understanding that the initial charge makes no difference, though Apple does recommend a full charge before using the iPod. I think this policy is more to prevent new users from complaining about a new iPod's battery life than any physical effect on the battery's long-term life.

    Wait... I'm confused by this thread...

    Did I do a good thing by charging my DS out of the box? [​IMG]

    It doesn't matter when you charged your battery because Lithium batteries do not have a memory. Whether it's drained or not, you can charge it whenever you want to. (That was the entire point of the Lithium battery anyway, Nickel Cadmium batteries were annoying).

    Ill just stay on topic:

    Here's what I do to drain the battery (my little sister thinks its broken then proceeds to stop touching it).

    If you go out to work or school, just put it to full brightness and do download play. Itll be dead by the time you come home.
