My question relates to apps and closing of them. I'm wondering if they are running in the background and consuming battery power even though I have "homed" my way out of them. Pandora, for instance, seems to be lurking ready to play more music, even though I have pushed the home button on the iPad. I'm not used to how tablets handle their applications. They don't seem to "close" like applications I run on my traditional desktop pc. The only reason I care is that my battery life doesn't seem to be what it ought to be. I haven't timed its longevity precisely but I don't think I'm getting the advertised 10 hours on one charge.
