    Once i get the Galaxy Nexus, i know i will have to "train" the battery.

    I know that I should let it charge all the way down then charge it back up to 100% for the first run.

    Besides that, what else should i do once i first get my phone/daily?

    Is the routine of charging overnight good for a battery?

    TBH, I have never followed this 100-dead business. I always charge it full before activation, then use as normal and it is always plugged in overnight.

    Also, if you get into ROMs, I always flash at 90% battery or higher. Just one of those OCD things I guess.

    You dont need to condition these batteries. That was the old NiCad batteries. There are charging methods that help them last a little longer though. Others know more than I do about this though.

    This is false for Li-ion batteries. This is rule-of-thumb with Nickle-based batteries, but has incorrectly been applied to Li-ion.

    I agree with the above. Do whatever makes you feel better about your battery. You don't need to train it unless mayhap the manufacturer says to.

    Actually there is circuitry in Li-ion batterys that prevent a true full discharge of the battery. But as stated above if it was possible to drain a Li-ion battery all the way down to zero it would not function. Phones only operate on certain voltages once a battery is unable to produce the required voltage the phone recognizes it as Dead/empty and it shuts off. There is still a charge in the battery but it is two weak to power the phone.

    Wow, thanks guys. im going to charge it to 0% anyways, just to be safe. it cant hurt. Verizon reps told me to charge it to 0%. It just shows how little they acutally know about androids

    Actually, discharging LiIon batteries down to low levels does harm the battery. Do it enough, and your battery will not hold a charge as well. Long story short, top off the charge whenever (like nightly), rather than let it run down to low levels.

    Don't listen to the Verizon reps. We know much more about phones than they do.

    When I was looking at the Razr I was showing the rep that sold me the phone things about it that he was totally unaware of. Then I started asking questions that I already knew the answer to and he was wrong about every single one.
