    I just but my 16gb iPad at the apple store this morning. When I turned it on it was at 94%. My question is do I need to completely drain the battery on the first use and then completely top it off? If so how many times I need to do so today?

    Thanks

    Nope, there's no need to do that with modern batteries. Just enjoy it. :)

    Overcharge it (charge until it won't any longer) and then use it all day until it discharges. I would even go as far as turning it on a few more times after it dies to get that last little bit of juice out. That's what I'm going to do at least. May not make much of a difference but I'm still doing it.

    With the new batteries it is actually bad to do that to them. The new batteries need to be used then charged. Not run all the way down and charged. They need the ions moved around all the time. These are much better than the old batteries.

    Yeah lithium ion and litium polymer batteries don't have a memory.

    You don't need to do that with modern batteries, especially Apple designed batteries with their own controller integrated that takes care of itself.

    Thanks everyone, love my iPad. I have been using it for over an hour and the battery only went down by 10%.

    Use Up Before First Charge

    Battery technology has come a long way in the last several years. As mentioned previously, there is no longer a "memory effect" so you can charge/discharge to any level without negatively affecting battery performance.

    However, there is a finite number of cycles in any lithium battery...and it counts as a cycle whether you charge a little bit or a all the way. To maximize battery life over the life of the device, you should deplete the battery as close to fully discharged every time to reduce the number of charging cycles.

    OK, my battery was completely drained...

    I opened it up and plugged it into my MacBook and it was completely drained. Is that normal? Well, silly question as this thing is brand new to all. Still charging and won't go to home screen.:mad:
