brand new core i7 battery life

[4now]

I just received a 15" core i7 MBP

After a full charge it calculates 4.23 hours remaining

Is this normal? This is what my 4 year old MBP used to say

Same here, never got 8-9 hours and never heard of a conclusive solution to it...
Do you use bluetooth?
Does it say 4 hours when you have all programs closed?

Yes that is normal considering the i7 is a power hog. while doing everyday tasks you will only get 4-5 hours.

Remember one thing, you will NEVER get the same hours they advertise. NEVER. Unless you just turn your computer on and have no apps open at all (but I doubt that will give you 7-9 hrs anyway)
