ASUS UL80Vt Battery Life

Relative Battery Life

The coup de grace for the UL80Vt is the battery life. Look at those charts and try to find anything else for $800 that can match the ASUS UL80Vt. (Note: the ASUS UL30Vt doesn't count, since it's pretty much the same laptop in a slightly smaller package.) Netbooks are able to offer competitive battery life, sure, but they're less than half as fast. The best-case Idle battery life tops out at just over 14 hours, but even a more demanding test where we load four web pages every 60 seconds - including one page with three Flash ads - still ends up at nearly 10 hours using the IGP and stock CPU speed. What's more, you can run with Turbo33 and the G210M and still get over 6.5 hours of web surfing.

We've dropped the other video playback tests, mostly because they're all very similar to the x264 results. HD DivX will last about 10-15% longer, and lower resolution videos would also improve on the results, but in general you can expect 5 to 6 hours of video playback with the UL80Vt.

The relative battery life is the final element, putting things into perspective. The UL80Vt has a higher capacity battery, so getting more mobility is somewhat expected. In the lowest power mode (IGP + stock CPU) the UL80Vt can provide nearly seven minutes per Wh, which is just slightly less than the ASUS 1005HA netbook. Turn on Turbo33 and battery life drops by about 10%. Running stock with the G210M enabled on the other hand results in a drop of 46%. Internet surfing with Turbo33 + G210M doesn't really change compared to stock with G210M, with only a 1% drop. The results here are in a test that happens to be more demanding than our MacBook testing, so the stellar battery life is even more impressive. Is it any wonder we're impressed with the ASUS UL80Vt? You get awesome battery life with reasonable gaming and application performance, all for just $800.

    Thanks for that; now go blow more smoke up Jobs' arse and leave the real discussion to people that can think.

    Calling this a cheapo Asus to try and make you Mac look better is pathetic. What makes it cheap, other than a plastic body? Most laptops are plastic shells, and this is still $40 less than the plastic MacBook while offering superior battery life and gaming performance. Plus I wouldn't have to put up with OS X and its quirks. Anand may love that stuff but I'd just as soon stick with Windows. No contest over glorified Apple.

    Congratz to ASUS for the UL80Vt which looks to be a very nice portable machine that still has some pretty reasonable gaming performance coupled with great battery life.

    ASUS has made some great computers. I picked up a "Lamborghini" a few years back and still really like it. However the very short battery life and heft did not make it the best travel companion.

    I recently picked up a new Sony Z-series with a 2.8GHz processer, a couple extended batteries, and built-in Bluray. Granted it wasn't cheap, but the laptop is pretty slick. Sony allow put a great display on it and Blurays look outstanding. Importantly - it plays Torchlight great...

    "... if you're talking a difference of 10W to 14W, that's a 40% increase in power requirements - or 40% less battery life."

    I believe the correct statement is "29% less run-time":
    RT = Wh / w ; RT reduction = 100% * (1-10w/14w) = 28.6%

    By analogy, your metrics would suggest a 100% loss in run time (= zero time) if the draw was 20 watts, whereas its actually a 50% reduction.

    Sorry... was being lazy when I wrote that. It would mean the lower power gets 40% more battery life, but as you point out the higher power draw is 29% less battery life.

    Notebookreview's forums have reported major stability issues with that specific model:
    http://forum.notebookreview.com/showthread.php?t=4...">http://forum.notebookreview.com/showthread.php?t=4...

    That's really uncommon for Asus laptops, but seems to be the norm for this model, so...I take it the review unit didn't have those issues?

    I run Folding @ Home on both my CPU and GPU when I'm not gaming or watching Blu Rays, so one way or another my hardware's always getting hit hard...need it to be 100% stable.

    Also, regarding Vista or 7 losing power settings, I've never had that happen, though I always use "always on" and always do a clean install of the OS (I wasn't running much Asus software on my N80nv on Vista, and didn't install any under 7).

    I didn't have any stability issues with the G51J during testing. That said, I highly caution against running Folding@Home (SMP or GPU) on a laptop. I used to do that and found that it seemed to cause serious problems after 6 months or so... that it just pushed the hardware beyond where it was intended. I sometimes wonder if all the "failing NVIDIA mobile GPUs" isn't somehow related to a lot of people running such apps, but that's probably oversimplified.

    In short, while I respect what the Folding teams are doing, I've determined that intentionally stressing hardware is a good way to make it fail sooner rather than later -- even if the hardware was once "100% stable". The benefit to me personally doesn't outweigh the cost... and if you're running a "folding farm" with desktops, your costs can very easily scale into the realm of $100+ per month for power, let alone hardware. :|

    Thanks for the info! Glad to hear it was stable.

    I guess my N80 is a guiness pig for Folding then. If it does fail, that'll force me to upgrade :-D

    I'm currently frustrated because I want to buy a new laptop, but it seems every manufacturer only ordered 1366x768 screens, be it for 12", 14", 15.6", or even 16" or 17" laptops.

    I was seriously considering an Asus N81Vp, and the only screen available is.... you guessed it, 1366x768. My current laptop, an Asus F8Va has a 14.1" 1440x900 screen, so you may understand my disappointment.

    I think manufacturers are trying to squeeze every penny they can putting those cheap 16:9 screens on every laptop. They do not realize we, the consumers, also use our laptops to work and not just to watch movies.

    1366x768 is ok for a netbook, not for a real laptop.
  • strikeback03 - Tuesday, December 15, 2009 - link

    Seriously. The UL50 (15.6" version) sounds like a laptop I would consider, but not with anything less than a 1680x1050 screen and a decent contrast ratio.

    On a side note, has anyone had trouble with Win7 blanking their screen but not actually turning it off? On both my desktop and laptop after the "turn screen off after" time has elapsed, the screen will flick off then back on, and stay on but blank. Any way to fix this?

    Looking forward to a review of the new ASUS EeePC Seashell 1201N-PU17-BK. That's an interesting one - dual-core, ION, 12" display, etc.
