I think I figured out what the “S” stands for in the iPhone 4S. Now, to be clear, I love my new iPhone 4S. I talk to it even when there isn’t a human on the other end of the line. Sometimes it talks back. But one thing that literally sucks about my iPhone 4S is its battery life. And I’m not the only one complaining.Today, my iPhone died after about 8 hours—not even enough to get me through a full day without recharging (and this is typical). This was not 8 hours of constant use (unless you count the constant pinging of notifications, which may be the culprit). It was 8 hours total from the time I unplugged it in the morning and took it with me until the screen went black at around 4 PM.
