Dell XPS L501x Battery Life: Good but the 9-Cell Would Be Better

The default battery in the L501x is a 6-cell 56Wh unit, which is more than the paltry 48Wh 6-cell batteries in many laptops but not quite at the 63Wh level seen in others. The combination of Optimus Technology and a reasonable battery means we should see good battery life, but nothing record setting. That's pretty much what we get, with a few oddities.

Battery Life - Idle

Battery Life - Internet

Battery Life - x264 720p

Relative Battery Life

The L501x comes out ahead of many of the 48Wh laptops in the idle, despite having a larger 15.6" LCD, so the slightly higher capacity battery balances things out. Internet battery life is a different story, dropping the L501x down below the N82Jv but still slightly ahead of the ID49C. As bad as that result may look in the chart, it's also still 16% higher than the Toshiba A660D with a 16.7% larger battery, so in that particular test the AMD P920 + HD 4250 matches the i5-460M + GT 420M on a relative basis. In contrast to the Internet result, the x264 playback puts the XPS back ahead of many of the 48Wh batteries.

We had hoped for something a bit more impressive here, but the results aren't bad. It could be that the higher LCD resolution affects some tests negatively (i.e. in the Internet test, you would see more of the test web pages and thus Flash ads further down the page might increase CPU usage). [Update: I retested Internet battery life at 1366x768 and the result didn't change; for some reason the L501x does far worse in that test relative to the other laptops.] HWmonitor also shows the battery at 4% wear despite over 10 cycles, so you might get slightly improved results with a different battery. Ultimately, though, the simple solution to battery life concerns is to spend an extra $40 and get the 9-cell 92Wh battery if you want to run all (or at least most of the) day untethered. There's a compromise in weight with the 9-cell battery, though, and it juts out about an inch below the laptop. I prefer the form factor of the 6-cell battery, but it's always nice to have a choice.

    Oh goodness, I must be blind. Nevermind me!

    I'm more than a little disheartened at the state of Windows laptops. Especially Dell. Dell is in the best position to really make the defacto Win 7 standard, but can't seem to get it quite right. I'm going to stick with my Latitude D620 for a little while longer. It's really not that nice. Adding an SSD helped. But it's indestructible for a plastic laptop, has good battery life, and I can get anything I need on Ebay if I run into any issues. The screen is terrible, but having a docking bay makes up for it. Plus, I can get a new screen on ebay too. Newer dell laptops may have a lot going for them in some respects, but they can't eschew the commodity label. In most cases, a commodity with not so hot battery life.

    That Latitude D620 is a metal-encased computer, the lid is magnesium alloy and the base chassis and internal structure is cast-magnesium - that's why it has almost zero flex. The D-series of Latitude laptops (and the Inspiron series that was based on it) had a brilliantly well-built (mechanically at least) design. And I agree, this should be the standard for all laptops.

    I like the hardware in the new XPS 15 but the first thing I thought when I saw it was I really didn't like the design - it's too thick and retro-looking. Not everyone wants Alienware/stealth designs that's a given but I don't know anyone who really liked the look of the new XPS series - despite the fact the M15x (R2) is 4kg+ it is still a lot better looking than the XPS 15. The Studio XPS 16 was and still is from a looks point of view a great design - shame they didn't consider getting heat out of it at all... This is all a shame because the hardware in the XPS 15 is amazing, and if it wasn't the fact I'd be paying the best part of £1000 for a machine I didn't really like the look of, I'd have put my money down and ordered one.

    Once you get a good coating of dust and daily grime in there, you can kiss this sucker goodbye.

    If I wanted a device dedicated to watching Blu-Ray movies, a 16:9 screen is great.

    However, if I wanted a laptop for general use it is a negative.
    Vertical space is very important as well to minimize the need to scroll up and down.
    The 16:9 loses about 10% of the vertical space vs 16:10 wide screen laptops.

    correct.

    16:9 on laptops is just plain retarded. Doesn't make any sense for me. Laptops are used for web-browsing mainly and work. 16:9 only is useful for movies and gaming.
    Actually for browsing 5:4 would be ideal but 16:10 is a fair compromise at least at somewhat higher resolutions.

    The laptop I would want would need16:10, mate and reasonable resolution. That basically limits my choices to 2000$+ professional offerings... it's ridiculous.

    I think MSI has a couple of laptops with 1650x1080 screens, but you aren't going to find 1900x1200 anymore unless you buy a 17" MBP.
  • erple2 - Friday, November 12, 2010 - link

    That's not true. But you are limited to 17+" laptops (HP's EliteBook, Dell's Precision line, Lenovo's Thinkpad line)

    Maybe I will be able to get a better deal!

    I've been looking for a laptop to use when I'm working from home, that will also handle light multimedia duties and occasional gaming, without feeling like it's going to break in half whenever I pick it up. My wife has a MacBook Pro, so the Envy would just be a little too close, and it's more expensive.

    I had also decided I wasn't upgrading my laptop again until I could get a decent screen, so I'm really glad the 1080p lives up to my hopes.

    This is exactly the laptop I've been waiting for. Now I just need to decide whether to wait longer in the hopes that all your bitching about a laptop that's not targeted at what you want will bring the price down.

    No tech sites every did a formal review of the Sony CW series that was refreshed in January. That laptop was possibly one of the best buys of the year and makes like these Dell and Asus offerings look like poop.

    Sony Vaio CW Series Model: VPCCW26FX
    Color: Pearly White or Black
    Intel Core i5-520M/2.4 GHz
    NVIDIA GEFORCE 330M 512MB GPU
    Display 14" 1600x900
    4GB DDR3/ 500 GB HD
    MSRP: $899
