Battery Capacity Testing
One of the charms of the netbook format is the promise that the little computers can provide very long battery life by using less powerful processors that consume extremely low power compared to current top-performing CPUs. Netbooks have quickly developed a reputation for sipping power and truly providing the ability to power a flight-long session or a work session for a full 8-hour workday. This has been helped along by manufacturers who have been beefing up battery capacity in more recent netbooks and claiming increasingly longer battery life in their specifications.
Of course you didn't come to AnandTech to see a list of manufacturer's claims, you came here for real world test results. Like notebooks, the battery life claims in netbook specs really don't provide the kind of information most buyers are looking for. Why specify battery life with the netbook wireless LAN turned off as most manufacturers do? The most visited websites use flash imaging, so why test with just non-flash websites to inflate battery life numbers? Do you really care about how the battery lasts with very long idle periods? We believe most want to know how long a battery charge lasts when a netbook is used as most people use them. Therefore the AnandTech battery life test is conducted with a wireless internet connection constantly on, viewing pages that contain some flash images among the text.
In AnandTech notebook battery testing the screen brightness is calibrated so that is equal on each tested notebook. The netbook is a particular challenge in this regard, since the highest current netbook screen resolution is 1024x600. We have several versions of standardized brightness calibration software, but the lowest resolution supported by any package is 1024x768. Since it makes little sense to test battery life with an external display we addressed this issue by setting an ASUS 1000HA to the middle of its brightness adjustment scale. Other displays were visually matched to the mid-level brightness of the ASUS 1000HA screen.
All hibernation and power management schemes were disabled on the netbook, and a wireless connection was established from the netbook under test while the battery charger was still attached. We connect to a script at anandtech.com that cycles among a group of standard anandtech.com pages that contain text, charts, graphs, and flash elements. The pages are continuously cycled at a fixed interval. The charger is then disconnected and a stop watch started. The test is run until the netbook shuts off due to low battery power. This is the same Battery Test run in our recent MacBook Pro article.
Results are reported in hours and minutes and provide a comparison of battery performance under common usage at the most demanding conditions. Please keep in mind that the AnandTech battery life results represent a realistic usage scenario. If you use an Ethernet connection and rarely use wireless your battery life will be slightly longer. If you surf the web with long intervals of inactivity, your battery life will again be longer. If you disable flash, battery life will also improve.

Where can I get one of these with Linux pre-installed?rad999 - Friday, July 17, 2009 - link
Visual is right on the money with his comments. Based in Taiwan I watched first hand that Asus tested the market and it paid off. Now they try to bleed the distinctions between a regular notebook and a netbook by offering old chipsets , larger displays and inferior specs amd rake in the cash.What is an atom CPU but a rebranded cpu from say five years ago.
Hav4e you ever tried to play a 3d game on a netbook, maybe upload video or make a DVD from a camcorder. It's a painful experience at best.

Atom CPU is ANYTHING BUT a re-branded older CPU. It is using a collection of older and newer Intel technologies in a combination to get the best performance vs. power consumption vs. price balance. They chose to go with an in-order architecture (which is a lot older than 5-years, you're talking Pentium II as the last Intel in-order CPU here) with hyper-threading (which is about 5 years old, but it's re-appearing in the latest Core i5 and i7 CPUs), with the latest or recent manufacturing process. It's a completely re-designed CPU for the specific marked to Netbooks and MIDs. The chipset could use updating though...On AMD front, they are using the old Athlon XP designs with their "new" mobile CPUs, so you get proven performance from 8-10 years ago multiplied by manufacturing process advancements; which allow the CPUs to be clocked higher with lower power consumption.
Do research before you flame please.
And why would you even dream of playing a 3D game on a $350 netbook? They're not made for performance or gaming. They are essentially designed to run Internet Explorer or Firefox, nothing more. Come on...

Atom is actually sort of a failure really. I believe that it's actually meant to compete with the popular embedded CPUs, such as the Arm and MIPS archictectures. But it consumes too much power for those applications and it's not nearly as flexible (the Arm and MIPS chips are sorta cut and paste "what u want" designs.)Atom is lucky that it found the netbook area, but it's definitely not exciting outside of its relatively low power envelope. Relative to other x86 chips that is.
Atom was born out of the Larabee project too actually. It's an offshoot of one of those cores if I recall correctly.

While I agree surfing the web is probably one of the most common things a netbook is used for, it isn't the only one. As the article admits, people also buy netbooks for those long plane or train rides. Considering internet access is not available on most commercial airlines, I think the battery testing should be a bit more broad.In particular I would like to see testing for divx and h.264 playback, or even mp3 playback while web surfing.

I agree. I travel a lot and usually watch movies or TV shows on the plane, if not I am listening to music. I am tired of lugging around a rather heavy 15" notebook and want something easy to carry and use while traveling.The majority of people I see on the plane or waiting in the airport are either doing work or watching video/listening to music, sometimes both. I would think doing a test with video playback would be a given as would using Office.
I am still bummed about the lack of wireless testing and was hoping for a reply today.

Just had an idea reading this article with respect to the battery power and performance tests.Put both the battery life and "general" performance results for each netbook/laptop in a horizontal bar chart as you have in this review, then have a slider at the top that lets you specify in percentage of importance (to the reader) battery life vs performance. When you slide it to the left, for 100% battery life and 0% performance, it would order the horizontal bar chart in order of performance for battery life alone. Slide to the middle and you have 50-50 for battery/performance and the chart sorts accordingly.
Yes, people will argue about the relevance of the battery and performance tests to their specific needs, but they will do that regardless. At least this tool would help to find a balance that is important to the readers using the results provided.

This is just terrible. Don't post any more articles like this. You'll convince the manufacturers that they actually have a decent product, and then they will not bother improving it ;)But seriously now, I am really disappointed by the slow rate of progress in the netbook area. They are all still using the same old crappy intel chipsets with terrible igp performance. Still on the crappy 1024x600 resolutions. Still no rotating screens and touchscreens. That is not evolution, that is milking the same old cow over and over.
I have the Gigabyte M912X tablet-convertible netbook, it is a model old as the world now, and yet it hasn't been surpassed by anyone yet. Even the fresh new tablets by Asus T91 and T101 are a step back, again with the lower resolution.
And here I was hoping we would even have multi-touch tablets by now. The initial misleading advertising of the Asus T91 as multitouch (which turned out to be about the touchpad and not the screen, damn Asus) had hyped my expectations way high.
Ion or at least the faster Intel GMA X4500, dual-core Atoms or Via Nano, are all getting old already without even appearing in a netbook product yet. If even existing tech takes so long to be adopted by the industry, how can I even hope for some future tech? At this rate I'll probably grow old and die before OLED displays, Moorestown, external/dock graphics, usb 3 or bluetooth 3 arrive.

I agree. Totally! I am waiting ages already to see OLEDs and Ions in a netbook. But things look boring at this time.KeypoX - Sunday, July 19, 2009 - link
agree agree... this is total bs. Netbooks run flash like crap too. I dont care who's fault it is. Try to play two or more youtube at once your screwed.Also 400 for a netbook is about 200 to much. You can get 400 notebooks core 2 duo almost everyday now.
I remember this site a few years ago, every article was gold, it was interesting and seemed honest. What happen?
