    Is there a large difference in battery life when comparing the E1405 with the E1505? The screen is larger in the E1505, and it uses an dedicated graphics card. Assuming a 9-cell battery is used in both, and they're used for simple office apps, I hear the E1404 can last 6-8+ hours, but I've yet to read anything about the E1505.

    Can anyone answer this question?

    6-8 hours are alot of hours. i think that the E1404 will last slighly longer, but not that much longer than the E1505. The screen size difference is small, so not a great deal more power will be used. This is only really true for identically configured setups, or there abouts. If i had to guess at the number of hours, then i would say no more 4.5 hours, for the E1505, and 5 hours for the E1404.
