    I need to know how long does it take to fully charge your Evo out of the box for the first time? Reason being I have a 09:00 appt to pick up my Evo and cannot start charging it until around 10:00. I have to be at work at 1400 (2:00pm) so I do not want to interrupt my first initial charge if that is not enough time...:cool::cool::cool: :(:(:( Thanks

    It should say on the Manual, usually I just charge it overnight. Seidio would recommend an extra 1 to 2 hour charge after the light turns green. :)

    I have an extra battery that will be charging the night before, so I can use the Evo the moment I get it. :)

    Every time I've got a phone from sprint its at least had half a charge on it.. so if you're concerned about only doing a partial charge for the inital use then just wait until you get to work and start charging. if these are Lithium Ion then you don't need to worry about first charge anyways since lithium ion don't have battery memory like NiCad did....

    This is very true! I used to be the Director of Marketing for a cellular accessory manufacturer in South Florida called Shuttle Technology and Ni-CD (nickel cadmium), and Ni--MH (Nickel Metal Hydride) batteries were the only ones that actually develop a memory. Lithium Ion batteries do not have battery memory as you have mentioned.

    With that said, I always advised my clients that it is always good to do a complete discharge, at least the first couple of cycles, even with a Li-Ion battery just to be sure that your battery will last you longer. Since Li-Ion doesn't develop any memory, you are fine to charge it as little or as much as you want and it won't harm the battery. I guess it's just a habit of mine to do a complete discharge.

    Not many people are willing to wait until a device is fully charged before playing with it. I already have a car charger that fits it so I'll be plugging it in as soon as I get in the car and then once again when I get home. I can mess around with it while it's plugged in. If you don't have any place to plug in, I wouldn't worry about running down whatever charge it has in it when you get it. You won't hurt it.

    When I got my Evo Friday it was about half full. It carried through my shift of 930am to 5pm. I think I did let it charge on my lunch break for 30 minutes.

    I had actually asked this question in another battery thread but it never got answered. So it is best to do a complete battery discharge the first couple times? A buddy of mine told me this but I could never get confirmation.

    Die I have done this with every single phone I had and my batteries always were conditioned too last longer than I expected. For me it's definitely habitual and definitely something I would recommend because you can't go wrong in doing so. Why chance it yknow?

    Don't worry about it, just use it. These batteries don't have a "memory."

    Sounds good to me. Thanks again!

    P.S. Too bad I'm in jville. Would be nice to meet up with you guys down there and mess around with our new phones.

    I assume jville means Jacksonville, but when I first read the sentence I thought you were saying you were in juvenile hall (i.e., prison for youthful offenders).

    That's what I always believe for my laptop and cellphone initially. So, does that mean I should play my evo4g till battery dead, then turn it off, charge it completely?

    guess i might charge my phone during my work for the whole morning, maybe a little bit afternoon, then fire it up after that

    The science and performance behind the Lithium-ION batteries is much better although a lot more unstable. The only real requirement for Li-I battery maintenance is to move the electrons through the battery once in a while. This means USE THE PHONE. Not too hard to do and say once a month drain it totally so all the electrons can pass through the battery. When storing an Li-I battery for extended periods charge it to about half way. this prevents bulging and keeps the chemistry a little more stable.

    As far as what to do the first day. Use it. Don't worry about that warning that says you must charge it to 100%. Chemically it doesn't make sense and I don't get the politics behind putting a warning either. Make sure to condition it correctly though, and for the first few charges go from absolute peak to dead. If you miss a full charge or don't kill it completely within the first 5 times don't worry about it, but try your best to charge completely and drain completely 5 times. The chemistry should stabilize then.

    The "use it" advice is perfect!

    New batteries make it unnessary for a full discharge, but I've always done it because almost all battery makers suggest a full discharge. I think it's more to ensure that a full charge is done on a regular basis rather than partial charges.

    I just see it as my way of ensuring that the battery has received a proper full charge.

    I drain all my rechargeables at least once/30-60 days without ever interrupting my use since full recharges can be done while sleeping or during prolonged work activities.

    So u were suggesting go charge new batteries when u have it. or should i drain the battery at the first time b4 full charge?

    Well, everything i have read about Li-I batts is that its not good to compleatly discharge the batt, BUT this is a debate i have seen argued both ways many many times. BUT most official things I have read says to keep the batt topped off whenever possible and if they batt gets below 20% capasity it can damage it, but the phone/batt chip already adjust for this b/c when it reads "0" batt left, its really like 25% to keep the batt from being messed up. BUT like i said, i have seen this argued back and forth both ways over and over again.

    Well you are kinda right djdisturbed. Li-Ion batteries won't recover if drained too far. All electronics that use Li-Ion batteries have a system to shutdown the device when depletion gets too far. Ever notice how all Li-I device shutoff completely instead of slowly dim out. I know in a phone it's all or nothing, but something like a RC planes it's still very common to use Nickel batteries because the user can tell the servos are getting slow instead a sudden shut-off. So yes, you are right it's bad for the battery to be totally drained, but modern electronics will prevent the battery from going to that critical level. NEVER store your battery totally drained that can cause it to never be charged again.

    Lol yea sorry, Jacksonville FL. Unfortunately I'm a bit to old to go to juve, they'd take my ass straight to jail =P
