    I bought MBP 13' without retina display(2012) model 2 weeks ago.
    Apple says we will get 7 hours of battery life. But mine lasts only for 5 hours.
    Is something wrong with my MBP or is it normal ?

    How much battery life do you get on your MBP13'?

    Battery life depends on CPU usage and display brightness.

    I have a 2009 MBP which can get 5 to 6 hours of battery life when I just read some text or write something or browse the www at medium display brightness.
    The same MBP can also get just two hours of battery life when watching YouTube excrements in full HD or editing video or playing a 3D game at full brightness.

    The amount of battery life that Apple says... is very inconsistent due to the fact they test with minor processes open.

    If you are actually USING your notebook to its full potential... It will not last.

    As with any question regarding usage -- depends on your usage. You're only going to get the battery life that Apple states if you have the same or similar usage. Usage that requires more power will drain the batter faster and vice versa. It's impossible to answer your question for you. You need to determine your baseline and compare over time if you want to determine what's normal for your usage.

    It's a lot like driving your car. If you leadfoot it you'll get lower fuel economy. I can get many hours out of my MBP or I can only get a couple depending on what I'm doing with it.
