How long are Macbook Pro battery’s supposed to last while not plugged in?

I just got a macbook pro a few months ago. My battery lasts for about 4-5hours when its not plugged into a charger and I am using it. Is that normal?

That sounds about right. I have a 13” MacBook Pro and the most I have ever gotten out of my battery is 6 1/2 Hours. I turn my brightness down to 50% while surfing the web. The 7 hour battery is advertised mostly for doing simple tasks like non-flash player websites and such. Movies will do the most damage to how long your battery lasts. You’ll be lucky to make it out with 2:45! But all in all this is a normal Macbook Pro battery! ?
