Battery Life Comparison

To provide the best perspective on battery life we tested with representative ASUS models from the original ASUS PC 4G to the ASUS 1000HA. ASUS was extremely helpful in providing netbooks to more clearly demonstrate the improving battery life on netbooks. Battery tests were run for the ASUS 1000HE and the MSI Wind U123 and test results were added to the base charts.

Netbook Battery Testing Results
Model Specified Battery Life Wh Power Tested Battery Life
Asus 1000HE 9.5 hrs 62.6 5:54
MSI Wind (U123) ? 86.6 8:27
Asus 1000HA 7 hrs 62.6 4:41
Asus PC 901 8 hrs 62.6 4:37
Asus PC 4G 2.8 hrs 38.5 2:10

The first ASUS netbook, the Eee PC 4G had a specified battery life of just 2.8 hours. This compares to the current ASUS 1000HE with a specified battery life of 9.5 hours - certainly a dramatic improvement. Our more demanding battery life testing showed the original ASUS Eee PC 4G with a battery life of 2 hours 10 minutes with improvement in the 1000HE results to 5 hours 54 minutes. However, the MSI Wind U123 is clearly the battery performance king among netbooks tested in this roundup. The Wind U123 turned in a benchmark-leading 8 hours 27 minutes of battery life while constantly connected by Wireless LAN to a website with flash content on every page.

With netbook architectures so very similar in recent designs the most revealing specification is the Wh (watt hours) battery rating. The voltage and mAh ratings were converted to Wh and the advantage for the 9-cell MSI Wind U123 is almost 40% compared to the Wh rating for the 6-cell ASUS 1000HE.

Netbook Battery Life

Our first thought was that the extra power trade-off in the Wind U123 must be increased weight, but that is not the case. The 9-cell Wind U123 weighs almost the same as the ASUS 1000HE. This makes the MSI an even more impressive performer in the battery life derby.

    I have an MSI notebook with buttons that seem to be much like those of the Wind.

    Many buttons (keyboard and touchpad) have to be pressed beyond the "click" in order for the press to register.

    When I saw this article I was hoping for a comparison to some of the low-end larger-screened notebooks available. I have been seeing Newegg deals on 14 and 15 inch notebooks for $350-400, I'd expect these to provide 3-4 times the performance of the tested netbooks but it would be a nice point of reference for those who are looking for a cheap system that doesn't need to be as portable. If you are buying for your 6th grader to do their homework, size and weight are less important than if you are flying cross-country.

    Also, i wouldn't say BluRay playback and gaming are the only areas unsuited for netbooks. After all, a netbook with Ion would be able play BluRay files (off a hard drive at least), but nothing short of a much after processor is going to make tasks like photo editing or video transcoding tolerable on a netbook.

    I dont see the difference between 3 pounds and 6 pounds... Netbooks are cute but have no more functionality than a cell phone.

    I have seen people in school with them, they generally disappear and have a 15" laptop very soon.

    Just some general comments as I agree with the above post. This article did not really answer the question about whether or not a Netbook can replace a low end Notebook you can pickup on clearance at places like newegg or tigerdirect. I am just looking for an inexpensive second system to toss in the bag when I travel and maybe something the kids can use while I am at home. The size of these would be perfect as the company I work for has our notebooks so locked down that even windows media player is no longer active. I will be lugging two systems around so weight and size is very important.

    I want to know how well it handles office applications, can it play movies/tv shows I transcoded for travel and how well does the wireless connection work. If I want to watch a TV show on Hulu does it offer decent enough playback quality via the wired or wireless connection. I watch most of my TV shows this way when traveling. How is battery playback when watching movies as those four hour flights showing the same movie over and over get boring.

    Someone already mentioned this but do the webcams work and is skype video supported as I like to see my kids after getting back to the hotel room. How is the audio quality with a pair of headphones attached? I do not game so that is not important but it would be nice to know if Peggle or Disney Toon Town or other kids games play on it. At home I could probably trust a couple of seven year olds with the machine.

    Most of the articles around here answer my questions and it is why I like visiting the website but this article left me with more questions than it answered.

    So, the webcams work as intended with descent perfs. I tested a MSI U100 6 month back and webcam was great. The audio is also with standard quality and there is nothing to cry about. Most of 2D games will work on it. Even Counter Strike 1.6 works flawless with 800x600.

    The image seems to show the 1000HE with an illuminated keyboard, yet no text in the article refers to this. I like this feature; shouldn't it have been at least briefly touched upon/ added to the comparisons?
    After all, netbooks are ultra-portable and mat be in some very shady, or porrly-lit, locales.
    (although it did lead me to a merry search involving stick-on keys, glow-paint, etc). Apparently this will be a feature in upcoming Asus models (unclear whether just notebooks or also netbooks)

    The keys on the 1000HE do not illuminate or glow.

    I assume this is a typo?

    "The N280 is essentially the same CPU as the N280"

    You could have a much more thorough article if you didn't stop with just the N280 comparison... Why not compare all the CPU's to themselves?

    The Core-i7 is essentially the same CPU as the Core-i7.
    The Pentium 4 is essentially the same CPU as the Pentium 4.
    The Phenom II is essentially the same CPU as the Phenom II.

    Typo corrected. Thanks for letting us know.
