If you power the iPhone off you will not get any indicators. The battery charging symbol it seems you are describing is the one when the iPhone is on, but only asleep. You can see this screen by powering the phone on. Then once it's on plug it in, then click the sleep/wake button on the top right of the iPhone. Next, click the sleep/wake button again and you should see the battery status screen.
