What is "normal use" in your opinion? Gaming? Text editing? WiFi, Bluetooth? Web surfing? See, there is no "normal".
Battery life and charge cycles vary by use and configuration. See www.apple.com/batteries for more information.

Read the fine print. They say 'up to' and the parameters used to achieve the seven hours simply do not relate to real world usage.
Battery life is a function of the open applications and the tasks being performed on the MBP. My personal experience has been that 60%-70% of the advertised battery life represents realistic expectations.
Not knowing exactly what you were doing I cannot comment if you are doing well or poorly in this regard. here are a couple of documents that you may find useful:

I have not played a single game, have the brightness on 50%, skype and google chrome are running with no keyboard brightness, wifi on, and no bluetooth. And i get around 3 hours of battery life doing this.

Skype is a CPU/GPU resource glutton. If you turn it off, you may find a noticeable increase in battery life.

Thanks for the tip, ill try without skype for a while. The time under the battery never stays consistent though so ill get back to you later. It goes up and down by half an hour even if I dont change my activity, but Ill see if it helps.

The time left shown in the battery icon drop down menu in the menu bar is of questionable reliability. Theoretically it gives you the battery time remaining based on the exact operating conditions for that given moment. My experience indicates that the fluctuations are best a general guide, not a precise metric.
