How's the battery life like for iPad Mini? On the Apple website, it claims that I could watch videos for up to 10 hours but I know that certainly is B.S. because on my iPhone 4S, I can't even surf the Internet for more than 3 hours. I've heard that the iPad mini has middling battery life. How long can the iPad mini's battery last for surfing the web, reading and streaming videos? On my iPhone 4S, browsing the web, reading and stream videos for about 2 hours is going to get the battery life below 20%. And this is annoying. I'm worried that the iPad Mini is the same, or even worst.
