ASUS UL80Vt Benchmarked - Battery and LCD

Finally, we have perhaps the most interesting aspect of the UL80Vt. Decent performance and a reasonable size are nice, but there are plenty of laptops to offer those amenities. What truly sets the UL80Vt apart from most other Windows-based laptops is the battery life. ASUS claims "up to 12 hours", and we decided to check their claim.

Battery Life - Idle

Battery Life - Internet

Relative Battery Life

Idle battery life reached nearly 13 hours… and that's what Turbo mode (overclocking) enabled. Granted, the system was sitting idle -- hardly a realistic usage scenario for most users. However, light office use isn't going to be much more taxing than our idle battery life test, and if you decide to disable Turbo mode battery life can only improve. In the far more pertinent Internet battery life, ASUS still achieves record-setting performance. Our initial test (we haven't had time for multiple test runs) came just shy of nine hours of continuous Web surfing. That's with several flash ads on be active website page, which again should be a bit more taxing than what many users view.

Looking at battery capacity and relative battery life, we finally have a true laptop that can actually trade blows with Apple's MacBook line. We never have been able to determine exactly what Apple does in order to achieve their high battery life, but clearly part of it has to be using lower voltage CPUs. ASUS follow suit by using the Core 2 Duo SU7300, which actually surpasses Apple by going with a 10W TDP CPU. Apple currently uses the 25W TDP SP9300, while some previous models used the 17W Core 2 Duo SL9000 series.

Even overclocked the SU7300 practically sips power in comparison to many other CPUs. We measured average power use of 9.5W for the UL80Vt in our internet test compared to 21.1W for the Gateway NV52 and 15.6W for the Gateway NV58. 10.1" and 11.6" netbooks only get down to 8.0-8.5W in the same test, and performance is obviously substantially higher with Core 2 Duo. What's truly impressive is that laptops like the UL80Vt previously sold for nearly $2000 -- sometimes more. With the boom in netbooks sales, manufacturers have apparently realized there's a real market for smaller laptops that get extremely good battery life.

Laptop LCD Quality - Contrast

Laptop LCD Quality - White

Laptop LCD Quality - Black

About the only fly in the ointment with the UL80Vt is the LCD panel. Here you can see our contrast ratio test results, and the results are down in the dumps with many other laptops. Sometimes I feel like a lone voice crying in the wilderness telling manufacturers that laptop LCD quality is a serious concern. I know from responses to previous articles that many of you agree, but unfortunately it's something that's difficult to quantify because many reviews don't ever look at LCD quality with quantitative results. ASUS has used very nice LCD panels on lesser offerings (i.e. the Eee 1005HA has an excellent LCD), and we have seen decent displays on other laptops and notebooks as well. If the system cost $25-$50 more but it had a 1000:1 contrast ratio (with an LCD that could still run at 250 nits), I wouldn't hesitate to give the UL80Vt an unequivocal recommendation. As it stands, it's a great laptop but it isn't quite perfect.

    This would be nice as my 2nd business laptop. My Vostro 17 is very nice, especially with the UW screen but it's heavy on busy days :) The weight, performance and battery life are amazing. Going to have to convince the Boss to get one hahah

    Unlike most people who commented thus far I'm willing to live with the sub-par display at this point. I'm in dire need to replacing my old Vaio VGN-FZ19VN and this looks to be even better value than the Acer 3810T series.

    Something I am desperate to find out though is if VT-x is enabled in this machine(it's for unknown reasons disabled in my Vaio) or not since I need to run a virtual linux machine for work.

    Not mentioning finding someone who retails it in Stockholm,Sweden ofc.

    [quote]ASUS has informed us that the Best Buy model of the UL80Vt will have a rubberized palm rest. [/quote]

    That helps, I hate the glossy plastic feel. I will have to check it out at best buy, I am skeptical about the bumpy touchpad too (I am not crazy about the new apple touchpads either, I prefer tap to click).

    If this thing had the same panel as the 1005HA, I would snap this up in a second. Seriously the LCD panel is the most important component on your laptop, and they want to skimp on it. Seriously if this is to compete with the macbook, they will need a better screen, my brother's new macbook pro has an incredible looking screen for a laptop.

    I am looking to upgrade my old 701 eeepc to something that can run windows 7, handle 1080 video streaming on my wireless network, and have much improved battery life.

    Keep in mind that the standard MacBook (historically) doesn't have a good screen; that's only on MacBook Pro, which costs significantly more. I wouldn't be surprised if the MacBook LCD is very similar in terms of contrast ratio -- mostly because that's the type of panel I see on 95% of notebooks/laptops costing under $1500.

    I had heard about the ul80vt months ago, and I was excited with everything about it: disk drive, dedicated graphics, ulv cpu, great battery life, chiclet keyboard... but I held off because of the screen.

    Instead, I went with an HP HDX16T, which I got on sale for $800 with a 1920x1080 screen, 1GB GT 130M, and a Bluray drive... it's nice enough, but it's a whole lot bulkier than a UL80, and battry life sucks.

    If ASUS continues improving the UL line though, I absolutely would pay a premium for one. Once they're on 32nm cpus... if they can kick up the resolution and lcd quality... these would be such a value.

    Just really wish there would be a nice light, well built, relatively small and light notebook without a glossy screen and a decent panel.

    I'll keep waiting I guess.

    I know ASUS and others are limited by what the companies that make the panels offer, but please push to make better quality screens at least an option. An extra $100-200 (even on an $800 laptop) would be worth it to me for a display I would be looking at for the next 3-4 years.

    The quality of the LCD matters to me.

    I hate many of these big LCDs with ridiculous low (TV) resolution. Last time I bought a laptop, I went with a MacBook Pro since I assumed it had a decent panel.

    I see little point in having the exact same sloppy product line as all the other notebook manufacturers out there.

    Another annoyance is the utilities that comes bundled with many of these machines. I had to return a Asus because of the ridiculous setup it was boggled with. Removing the anti-virus package gave me a serious bump in performance. Clean install please!
  • Visual - Monday, October 26, 2009 - link

    Now all that I want from ASUS is to replace the screen with hybrid multi-touch/stylus sensitive one, and preferably higher-resolution, maybe 1680x1050 so that it can work well in portrait mode and fit the many 1024 pixel wide websites.
    I'd probably pay almost double the current price for such a thing, but if they can surprise me and get the price lower, that's even better.

    Given that this is unusually ultra long battery life Windows notebook based on C2D, not on Atom, could you make one exception and include comparison with MacBook's legendary battery efficiency metric? I mean that cool graph that you used to put in your recent laptop reviews that said "Internet usage minutes per WHr" (you don't do this anymore, too bad :( I posted about it already)

    It's one uber crucial metric for truly portable laptops, could you PLEASE make this comparison graph for Asus vs latest MacBook just one more time, just for this great Asus one, please?
