    As the title says...

    I am looking at getting the asus K42JC-A1 or waiting for the envy 14. The battery life on the K42JC-A1 is best case 3-4 hrs.

    Thanks

    Yea, idling with low brightness with Wifi off.

    Real time usage is likely to be around 5 hours or so.

    59wh, for 5 hours, is 12 watts per hour, which is about the margin for the i5 and light use.

    Nobody knows yet? Perhaps wait for some reviews. We just have claims from HP & speculation. It is likely Levi's estimate is correct, however.

    The Envy 14 has an 8 cell Li Ion battery in contrast to the 6 cell of the K42JC-A1.

    What kind of continuous run time could i expect with the envy 14 when watching a ripped DVD off the HD?

    No one knows because no one has this notebook yet. Anyone can speculate but take it with a grain of salt.

    If the other Envy Slice batteries are any indication, probably $125 as an add-on at time of laptop purchase.

    Either way, it looks to me like the ENVY will have the best battery life in a (good) notebook that's actually released in the US. Also, it's got the best battery life in a notebook that I might actually purchase.

    dm4 with similar battery and hardware lasts 5 to 6 hours on surf wifi usage. Envy should be about that 4-5 hours (radiance screen eats some extra battery...)

    The Envy 14 has an 8 cell battery though, and the dm4 has a 6 cell.

    Battery life on the Envy 14 should be roughly equal to that on the dm4t, as HP quotes 7 hours for both of them.

    I think it is nice to have something as a worst-case number?

    I think the battery life will probably be about 14 hours without a slice battery, 37 with it.

    if not that, then about 1 1/2 without, 3 with.

    OH, I've got an idea. Let's wait until someone has actually touched one.

    I doubt Amazon is doing any battery tests, especially on laptops that have not even been released yet.
