Design and Other Considerations

Before we get to the benchmarks, let’s take a minute more to look at the design and aesthetics on offer. We’ve covered most of this already—the XPS 15 L501x had a decent keyboard with only slight flex, there are lots of matte surfaces to go around, and you get some of the best sounding speakers you’ll ever hear in a laptop. Except, this isn't exactly the same keyboard as the previous model, and the chassis feels slightly less sturdy as a result. More on this in a moment.

One upgrade that we didn't get to test previously is the 9-cell battery, and this is one of those hit-or-miss upgrades. On the one hand, you increase battery capacity and battery life (by about 55% in our testing). Unfortunately, the 9-cell battery really ruins the profile of the XPS 15, raising the back of the notebook almost a full inch and giving the bottom an uncomfortable bump that makes using it on your lap a dubious proposition. It's great for battery life, and if your laptop sits on a desk or table it's not a big deal; however, Dell should be able to put this much capacity into a better form factor with a few modifications to the chassis.

In the above gallery, we’ve included some comparison pictures of the 6-cell and 9-cell Dell batteries with ASUS’ 8-cell battery from their U-series. The ASUS battery is nearly as thin as the 6-cell but it’s substantially longer; it shows that it would be possible for Dell to fit such a battery into a 14” chassis if they were willing to rework the chassis and internal layout. Personally, I think Dell needs to reevaluate the battery design. While I really like the idea of a 90Wh battery, I don’t like the battery wart on the bottom of my laptop. Another option would be to go for a higher quality (and higher cost) Lithium polymer battery that could pack the same 90Wh into a smaller shell, which is the approach Apple tends to take.

Another tidbit worth mentioning is that upgrading your hard drive requires a bit of extra work. You can get at the memory, WiFi card, and the remaining mini-PCIe slot (occupied by an AverMedia TV Tuner in our test unit) through the single large bottom panel. The hard drive on the other hand is accessed through the top of the chassis. Interestingly enough, the top cover around the keyboard isn’t even secured by any screws; remove the battery and you can access a couple of the plastic clips that hold the cover in place. There are about twenty plastic clips around the top cover, and you’ll have to get them all to release before you can get at the hard drive; you’ll also need to detach the touchpad and media/power button ribbon connectors. While you won’t need to remove any screws, the end result is something of a pain compared to the simple bottom-hatch access most laptops use, and if you happen to remove the cover several times there’s a reasonable chance you’re going to start breaking the plastic clips.

The reason I get into the above is two-fold: first, it illustrates a design flaw and the difficulty of upgrading the hard drive/SSD. The other item to note is that the entire top cover is made of somewhat flimsy plastic, which feels more like Inspiron quality than XPS quality. The frame on the XPS line may be solid, but the actual shell around the frame is plastic and definitely not as sturdy as Dell’s Latitude line. I’d really prefer to see the XPS line go slightly more upscale—bump the price up $50 to $100 and give us a consumer chassis that feels like it will last. Or there’s the new Alienware M11x/M14x that might fill that niche, but aesthetics are still a matter of opinion and plenty of people dislike the bling that’s present on Alienware’s offerings.

Finally, let's discuss the keyboard. I actually liked the old L501x keyboard, and I sort of figured the L502x would be the same design. Well, it's not. The new keyboard is the chiclet style that has become so prevalent among consumer notebooks. I don't really mind typing on chiclet keyboards, and this one works well enough, but I felt there was more flex and less ruggedness to the overall design compared to the previous model. Some of that may just be my perception—I don't have the L501x handy to check—but as noted above the build quality feels more like a tweaked Inspiron rather than giving you the quality of a Latitude.

With that out of the way, let’s hit the benchmarks and graphs and see how the new XPS 15 compares to the old model, along with a selection of other recent laptops. Pricing for the reviewed configuration puts the L502x into direct competition with laptops sporting significantly faster GPUs—i.e. MSI’s GT680R can be found for just $50 more. What you get with the Dell is a more aesthetically pleasing design, a higher quality LCD, significantly better battery life (thanks to Optimus), better speakers, and a backlit keyboard. On the other hand, the GTX 460M walks all over the GT 540M in games, so if you’re looking for gaming laptops as opposed to Jack-of-All-Trades offerings, there are better options.

    Dell's service fixed and shipped back my Studio 15 in three days from making the call, and upgraded me to a 1080P monitor for free from a 720p one. I'd call that pretty good service. 3 years ago I would have agreed with you. Reply

    Are there any plans to review the Lenovo X220 and its Premium HD (12.5" IPS) display option?

    It's starting to look like a fantastic machine.

    8+ hours on a 63Wh battery.

    The request for a review unit has been sent, but so far no response. Unfortunately, Lenovo tends to be a bit ambivalent towards certain sites, ours being one of them. Reply

    That's unfortunate. I'm more interested in the X220T as a replacement for my aging HP tx2000, but of course the X220 should have similar (if not identical) performance. Reply

    I'm sorry to hear that.

    I consider Anandtech to be one of the few sites that provide both in-depth and unbiased reviews.

    Hoping for the best!

    I've been reading that Ivy Bridge will have some decent improvements over Sandy Bridge and give it a 20% performance boost over Sandy Brdige. Oh yeah, I forgot to mention it will be 22nm! Reply

    I'm waiting for a 14'' notebook, Sandy Bridge, NVIDIA GeForce 5xx (Optimus capable), dual-channel memory, SATA III and USB 3.0... do I really have to wait forever? Reply

    Thanks for the review Jarred. One of the complaints I have with Dell recently is the very restrictive upgrade list within a product family. I was recently tasked with a laptop purchase for my SIL whom has very specific requirements (long battery life, usable keyboard, <$650). Found a great build by Dell but they refused to allow for the upgrade to the 9-cell battery, it was only as an optional $175 ADDITIONAL battery. I've seen this with many builds of theirs where they market as upgradable but really mean only if you're willing to shell out for the whole part. That was a deal-breaker and Dell was off the list of choices....

    I appreciate the bolding used to designate what came with your particular unit as it's always been more difficult to tell the parts in the reviewed sample.

    Wanted to update my post to note that this particular XPS model does allow for the $40 upgrade to 9-cell battery. That is a huge improvement for very little money and while it does change the form-factor a bit unless that's a deal-breaker for you the added battery life is well worth it IMO.

    Honestly my perfect laptop would be a dual-core 15" with good LCD upgrade, dual-drive for small solid-state boot and larger mechanical drive (while not sacrificing the optical drive), and 9-cell battery. Give me that for under $800 and I think a good 75% of the buying public would be happy.
