ASUS Zenbook UX21 First Results: MBA-Like Battery Life Under Windows 7
by Anand Lal Shimpi on October 18, 2011 4:27 PM ESTFedEx dropped off our first Ultrabook this morning: the beautiful 11.6-inch ASUS Zenbook UX21E-DH71. We just got the first battery life results out of the machine and, as expected, they are near-identical to the 11-inch MacBook Air under Windows 7. Given the similarity in platform and identical battery capacities, similar results here aren't surprising. The fact that there aren't any surprises is a very good thing as it means ASUS' default configuration doesn't include a bunch of battery-taxing bloatware. We'll be running more tests over the coming days of course but it never hurts to have an early look:
Performance is also in-line with expectations. The model we have features a 128GB SF-2281 (SandForce) based SSD and a faster CPU than the base 11-inch MacBook Air model giving it the edge in PCMark 7. Although the system is configured to sleep rather than shut down by default, a full boot from scratch (not hibernate/STR) takes only 16.7 seconds. That's actually in-line with how long an 11-inch MBA takes to get into OS X (17.2s). Very impressive indeed.
The machine feels extremely well built and is quite snappy thanks to its Sandy Bridge + SSD combo. More details soon!

"'It's been proven time and time again that Flash uses less resources than HTML5video."What (may) have been proved is that Flash VIDEO uses less resources than HTML5 video. That is not what the issue here is.
I can't comment about Windows. But on Mac the problem with Flash is NOT (or at least not only) the video playback, it is the idlers, the code that constantly runs on the CPU and never allows the CPU to fully enter low power modes.
Note that it is precisely THIS that the test was measuring.
Obviously "Flash ads" is a vague category, and, sure, maybe what Anand meant by the term was Flash ads playing back h264 video. But what most people mean by Flash ads is NOT h264 video --- it is some vector animation, some code to capture events --- and the dreaded idle handlers that I have discussed.
Given that HTML5 video does not come with a scripting language, it doesn't have these problems. Of course one could write JS that is extremely crappy in terms of how it handles idles, but as a practical matter it appears that the combination of real-world JS plus how Safari handles JS idling is substantially less power intensive than real-world Flash and the way Flash handles idling.

Flash also uses far less CPU usage for animations as well, not just video playback. It's far more efficient than HTML5. Not to mention more advanced and capable.Apples own HTML5 demos run like total **** on the iPad, max out the CPU and get single digit frames per-second. Meanwhile Flash on a less powerful single core Android phone can do the same things at a perfect frame rate. Theres many videos out there proving all this.

Couldn't the title have been"ASUS Zenbook UX21 First Results: Asus Eee pc-like Battery Life Under Windows 7
"ASUS Zenbook UX21 First Results: MBA-Like Battery Life Under Windows 7"
Considering the market share of Apple laptops and that battery life has fallen on the MBA...
It's all Apple, Apple, Apple with all the tech sites these days. Fair enough.

between the chiclet keyboard and huge trackpad, it does seem to be copying the Mac laptops somewhat.tayb - Thursday, October 20, 2011 - link
Or because Apple has industry leading battery life? My work provided me with a 15" MBP and that thing got 8 hours of battery life under the scenarios described above. 8 freaking hours. My previous laptop, a fujitsu convertible, managed about 7 hours with an extended battery and a modular battery in the optical tray.komoornik - Wednesday, October 19, 2011 - link
Please make sure to update the BIOS ( or EFI ) and drivers to the newest versions available :)billy_kane - Thursday, October 20, 2011 - link
Zenbook is too ugly thanks to its plastic looking and its washbasin likesd A side.MBA11 also can upgrading to i7-2677M
MBA11 with an awesome Thunderbolt Port but was there anything port of Zenbook can provide for such hyper data rate?
MBA11 equiped a KeyBoard with backlight but zenbook only say sorry when in darkness
MBA11 featuring 802.11n Wi-Fi and Bluetooth 4.0 but zenbook no
Wanna against MBA11 in battery life, please offset the backlit keyboard

He already had a more detailed comparison article (which was linked in the article)http://www.anandtech.com/show/4957/asus-zenbook-li...
I love the way it looks and so do many others, including Anand (who is a Mac fan)
It has USB3, which already has thousands of devices you can use with it. It's not as fast as thunderbolt but it is more useful. It's easily fast enough for external storage.
Not sure about the backlit keyboard but it does have way better speakers then the MBA.
It has 802.11n and Bluetooth 4
A backlit keyboard only uses a few mW, it's just a few tiny LEDs.

Does anyone know the model number of the Zenbook's battery yet?
