13" refurbished pro battery life

[bemiller777]

I just bought my first Mac this past week and absolutely love it. I went with the 13" 2.26. I am extremely happy with my purchase but I have one question...
How realistic is you claimed 7 hour battery life? I expect the battery to last longer and shorter depending on how you are using you Mac but sometimes I feel like it isn't performing as it should. As I'm typing this I have 88% left on the battery and 5:50 till empty (25% brightness and backlight off). I have itunes on but not playing.

The problem is when I try to watch youtube or anything else similar, the time till empty goes down a few hours. (from 6 down to 3 hours left till empty). Is this normal?

Thanks

Thats the joy of a very bloated Flash player! It's kinda frustrating, not something I notice on my iMac naturally but on my MBP it's annoying. It seems worse when watching HD or HQ videos, listening to BBC iPlayer audio it doesn't seem to be too bad.

At ~80% brightness, just after unplugging it.
