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.

    Hilarious... search for L501x and all you get are support documents for the XPS L501x, including a BIOS update. Search for XPS 15 and you get a bit closer. Just go to the following link and select the model you want:

    Nice screen at 1080p, but GPU is not up to the task. Even the cheaper Acer Timelinex 4820TG performs better than XPS15 (same core i5) in gaming and multiprocessing.
    So for XPS15, GPU fail while A/V is good.
    For 4820TG, GPU is good while A/V fails.

    You guys at anandtech should give 4820TG some tests, and see for yourself its benchmarks and gaming power.
    BTW, judging from your tests on XPS15, even the cheaper Gateway ID49 performs better in many games..

    Is it out there the perfect PC or Mac?Will it come the day when we can go to the store and grab the perfect computer? NO, it won't . I hope not, otherwise the experience of shopping/ reviewing computers will be meaningless. If you want a quasi-perfect PC just build a desktop or if you want a portable one well, go with the market.
    Moreover,I like this XPS15 because its features, but not because of its design. Dell could have gotten one of those guys that design for Apple and get something aesthetically beautiful to the eye. But what is beautiful for me, might be ugly for you though.
    If you need a Mac to go out to a cafe and get looks of approval from people, or being accepted by a social group, well do it if you have the means to spend for a computer. I do love Macs but the MacPro are not professional at all.
    As for PCs there is variety out there, there is more space to innovate, and there are many of us that want something more flexible in hardware, and perhaps OS system. Certainly, Windows 7 has its flaws, and it won't be perfect, but guys you have options... if you don't like this PC don't buy it, don't even read the reviews; also, and if you have problems with self-esteem, and therefore need a machine to show off buy one appealing to your friends and stop whining like a child.

    I'm about to buy one of these, but I want to know if it's at all possible to install XP on it. Yes, I'm a software luddite etc. who runs XP on a q9550@3.6 and so forth, but I like the results.

    Any info is appreciated.

    Hopefully it'll as good as the review says.

    Out of curiosity, I was just checking the site
    http://configure.us.dell.com/dellstore/config.aspx...
    That's the correct model, right?

    As of this moment, the option to upgrade to full HD resolution is gone.
    Just a few days ago, it was priced at $195 for the upgrade. (too high demand?)

    For whatever reason causing the hike and the subsequent removal of that upgrade, the gold-medalist is not so golden now IMO. Hmmm...

    Looking on dell's site for the 1080 screen today, can't find it. Is it still available?
  • Taimfrey - Wednesday, December 15, 2010 - link

    I've been looking at this laptop for a while and have customized it on their website a few times to figure out what I want and how much I want to spend. Tonight I got on and the option to add the 1080p screen was no longer available. I called Dell and apparently now only the alienware laptops have the 1080p screen as an option. I hope this is a temporary adjustment due to the holiday, or else I'm going to buy somewhere else. Seems like a rather poor move on their part, especially after a review like this.

    The 1600 x 900 LCD display on the XPS 17 is for me not usable for image work and unpleasant to use period. It does not have any viewing angle you can tilt the lid to that will provide a consistent appearing image. Lift your chin and the image changes. If you tilt the lid so the webcam has you centered the image on the LCD is washed out like you are looking at it through mist. There is no sweet spot. As you tilt the screen its a continuous unbroken progression from washed out to loss of detail in dark areas. In any given position just lift your chin and the image changes. The only thing wrong with this laptop is the LCD but even the replacement they sent has the same unacceptable screen. I'm returning both. I'll just have to make do with my 5 year old 17" Inspiron 9300 which doesn't have any lid tilt viewing angle issues. Hopefully Dell will make a quality 17" screen option available at some point.
