I have the 2G iPod Touch and have noticed as of late that my battery seems to be discharging when not in use. I don't always turn the Touch completely off, but the battery shouldn't discharge that quickly. I have 3rd party apps on it. I'm wondering if any apps could be draining the battery when not running. Is that possible? Lastly, is it best to charge the battery when the Touch is entirely off or not? When I say "off", I mean holding the power button down until you can shut down.
