Does the brightness and bl keyboard on fullest high settings make a great impact on the computer's battery?

How long would it last on lowest both vs highest both?
 
1. Yes.

2. Don't know, since there are a variety of other factors (what you actually do with your MBP) and there are also a lot of MBP models with different battery capacities.

1. Some impact.

2. This mostly depends on how you use the laptop. Apple quotes 7 hours for web browsing with medium brightness.
