I looked in the manual, but how long does it need to charge for a full charge? I'm guessing 4 hours?
The manual is a bit vague on battery and battery life.. For example, nowhere is there mention of how and when to charge the battery.. for example, let it drain first, or not, or maybe occasionally letting it drain down as with many of the new Li batteries.
I don't know what it is about batteries, and Apple, but they REALLY seem to hate talking about them, or letting you mess with them!
