Mobile Performance



We used the standard battery for the X300 for standard testing. The margin between the X31 and the X300 is too close to declare either of the two solutions superior in this respect. X31 made up its shortcomings for its battery on the hard drive side, while the X300 took to the processor.




There is no beating around the bush here. The X31 rains supreme in the battery life department. The docked X300 result was the use of a standard battery and the extended life battery, which only brought the battery life to just shy of 6 hours. Meanwhile, the X31 docked can still linger around 2.5 additional hours, and it used two standard batteries in its docked benchmark score. The X300's MediaBase seems to be at the heart of the power consumption issue. The extended life battery alone will give just over 5 hours of battery life and the standard just over 2 hours. This, in theory, should add up to over 7 hours, but instead, we see just shy of 6 hours. So while the MediaBase gives more functionality, it consumes a significant amount of power. The X31's extended life battery, meanwhile, should give over 10 hours of battery life.

    I currently have an x300. I travel a great deal and have had a problem with a spot appearing on the screen. I have already had the screen replaced once and soon to be again. My question is would the IBM x31 be more durable than the Dell 300? I have not been able to find a x31 to compare to.

    When anyone says Centrino, the basically mean the Pentium-M. Its just that Centrino is the more recognisable brand name. Technically, half the machines out there aren't real Centrinos since they use a 3rd party 802.11a/b/g chip.

    And I wasn't saying that the R50p was comparable to the X300, I just wanted it on the waiting list for reviews. IBM haven't had a serious Desktop replacement machine since the A31p over a year ago. (The G series doesn't count due to its sucky onboard graphics). It should be interesting what it brings to the table.

    "BTW, the T40 isn't all that much bigger than the X31.... I like mine :)"

    Um the T40 is quite a bit bigger than the X31, I had a T40 at work and have an X31 as my personal machine.

    Isn't this X300 acutally made by samsung?

    R50p is a "monster" in size compared to these ultra-portables.... review, yes...comparable, no.

    anyways....yeah, the X31 rulz....more expensive, but going cheap on laptops is often not worth it. BTW, the T40 isn't all that much bigger than the X31.... I like mine :)

    "The X31 rains supreme in the battery life department."...

    Anyway, the feature set looks a lot like the Sony ultra-portables, right down to the blocking of the VGA port when you stick the media bay on.

    quick request: would it be possible for you to review the IBM R50p when it comes out? Exected release date is november some time. Thanks
