i guess im doing what you call a calibration, charging the phone from dead to a real full charge. i think its only been about 2hrs. but its showing the plug in the battery and not the lightning bolt. but is it doing a trickle charge now?
how long should a full charge take? i think i might leave it plugged in while i go to sleep and unplug it in the morning before i go to work around 7am. im sure that wont harm it, right?
this should help

Standard Charging
Most lithium-ion batteries use a fast charge to charge your device to 80% battery capacity, then switch to trickle charging. Thats about two hours of charge time to power an iPod to 80% capacity, then another two hours to fully charge it, if you are not using the iPod while charging. You can charge all lithium-ion batteries a large but finite number of times, as defined by charge cycle.
A charge cycle means using all of the batterys power, but that doesnt 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. Each time you complete a charge cycle, it diminishes battery capacity slightly, but you can put notebook, iPod, and iPhone batteries through many charge cycles before they will only hold 80% of original battery capacity. As with other rechargeable batteries, you may eventually need to replace your battery
