ASUS UL80Jt—Battery Life

The UL80Jt has a mediocre CPU and a mediocre GPU, but the real question is, can it match its predecessor’s amazing battery life? Sadly, no.

Relative Battery Life

It’s not too much better than the U3x models that we had in the labs previously. Not to complain about 10.5 hours of ideal case battery life, but that’s significantly worse than the previous generation UL80Vt and only about 45 minutes more than the U30/3/5Jc trio. Given the cut in processing performance, I’m seriously disappointed.

I’ve been hearing some things spoken in hushed tones, mostly alleging that the Core 2010 ULV processors aren’t nearly as power efficient as the previous generation CULV processors, and our experience with the i3 and i7 ULV chips is proving this correct. If there’s only 45 minutes to be gained by switching to the ULV processors, it’s far more worthwhile to go for the regular i3-based system, especially if we’re talking about the difference between 9.75 and 10.5 hours of battery.

This isn’t to complain about having 10.5 hours of battery life, which is awesome in its own right, but it’s just not as impressive when viewed in context of the UL80Vt and the U30Jc. Things get not happy when we turn on the overclocking though, as we end up seeing less battery life than the U3x series.

    One of the more revealing side notes here is on the Nvida 310M - it's simply old and slow, with integrated GPUs on it's heel.
    I am ready to forgive an ultra thin/ light and notebook such as reviewed here not having a good GPU.

    But the real problem is NO current 13" notebook (except the SONY z-series) has anything better than the 310M.

    I am looking for a new laptop with an acceptable dedicated GPU, but there simply in none.

    Even more sad....look up the specs, the 310m IS the 210m

    They changed NOTHING but the new features, no die shrink, no additional sp's NOTHING

    Basically this. The G 310 was a viable graphics chip at the very beginning of the i3 generation, but at this point it's a sad caricature of a dGPU. Between the 210 and the 310, they really haven't done much other than add some of the new 300M technologies; the core is still exactly the same.

    This is why we can't wait for them to update these things to the GT 415M....

    Come ON. Nvidia changed the NAME, what more do you want?

    One difference, actually: the 310M supports Optimus, the 210M does not. Reply

    That's part of what I was referring to as "adding the new 300M tech", but interestingly enough, the first Optimus notebook ran off the G 210M. I was talking to Jarred about this the other day; here's the link.

    Take a look at the Alienware M11x - it uses a 335M, but only has an 11" screen. Reply

    if you want a 13" machine with decent gfx-power, get the acer 3820. it has a ati 5650 inside which should be even better then the downclocked 330m in the vaio z series. only downside is the lack of an optical drive, if you need one. Reply

    I think this review makes it clear that the current-gen ULV is a big disappointment...even the last gen ULV was preferable. The small jump in performance isn't worth it when the last-gen ULV gets at least 50% more battery life.

    I also can't understand why Asus has crippled the UL80Jt with slower GPU memory than the U30. What were they thinking? Was it worth saving a couple bucks?

    Anyway it doesn't matter because the next generation of Asus U-series notebooks (with GT400M-series GPU's) is already on its way, if you can wait a little bit longer....

    Sweet! Thanks for that link. Good to see they are moving on from that useless 310. I just hope they have a SKU with a matte screen, then they might finally have me as a customer! Reply
