Dell Studio XPS 16: the Eyes Have It

Battery Life
For battery life testing, we run all laptops at around 100 nits brightness. If you choose to run your LCD at maximum brightness, you may lose anywhere from 10 to 60 minutes depending on the laptop and the display. In the case of the Studio XPS 16, maximum brightness is 280 nits and uses 9W more power, so the impact on battery life is quite significant (see the idle chart below for reference).
We run several different battery life scenarios: Internet surfing (load several webpages using the wireless adapter every minute until the battery dies), DVD playback, x264 playback, and idle (maximum) battery life. For x264 playback, we copy a 720p file to the hard drive and loop playback using Windows Media Player Classic Home Cinema; we will include scores from other laptops, but it's worth noting that we did not have GPU accelerated x264 decoding enabled in previous laptop tests. We have battery life results for Blu-ray playback on laptops that ship to us with a Blu-ray drive. We've also included web surfing results (and DVD for the MacBook Pro) for the latest Apple MacBooks as a point of reference.
Battery life is nothing special, particularly when compared with similarly equipped notebooks. Purchasing the extended capacity battery does allow you to reach over three hours of battery life, but the same can be said of other notebooks. You can also see what happens if you turn up the display brightness. At maximum brightness sitting at the desktop, you only get 108 minutes of battery life. Perhaps that's just the price we have to pay for the beautiful LCD.
As we've mentioned in the past, Apple's MacBook and MacBook Pro provide an almost untouchable amount of battery life. To give you a true apples-to-Apples comparison, we've calculated the amount of battery life you get per Whr (Watt Hour) of battery capacity:
We can only hope that Windows 7 will help improve the battery life situation and level the playing field. However, we also suspect that the hardware manufacturers could be doing a lot more to improve battery life on their laptops. The closest we have come to matching the Minutes/Whr score of the MacBooks was with an ASUS N10JC netbook, which isn't even on the same continent in terms of performance. Apple is getting over six minutes per Whr, and most similarly equipped Vista notebooks are luck to come close to 3 min/Whr. Note that testing a MacBook with Vista using Boot Camp also cut the Apple battery life roughly in half.

I don't have updated scores with new drivers, but you can see the http://www.anandtech.com/mobile/showdoc.aspx?i=324...">original XPS M1730 3DMark scores - including scores with the CPU overclocked. I didn't have 3DMark Vantage at the time, so those scores are also missing. Basically, the scores are relatively close to the Clevo D901C laptop.Hrel - Thursday, April 2, 2009 - link
I have a Dell Studio 15 Series laptop T8100 320GB HDD X3100GMA... it's okay for the most part; wish it had some kind of useable graphics, but I couldn't afford the upgrade. Anyway, the slot loading DVD drive is a pain in the but! It quirks out sometimes when you hit eject and just keeps trying to eject the disc even if it's already out until you restart the whole thing; one time even after doing that it just wouldn't take discs for like 5 days at all. Then randomly it started working again. Not to mention if it ever DOES fail I'm gonna have to pay more for the replacement than I would if it was a standard cd tray drive; I REALLY don't like that choice of DVD drives.Also, on a 16" 16:9 Chassis they really should include a keyboard that has a dedicated num pad. Asus includes a full numpad on their 15.6" 16:9 chassis. On that note though, the keyboard on my Studio 15 is well laid out and pleasant to type on.

Where the measurements for the screen done with the out-of-the-box settings, or was it calibrated first?JarredWalton - Thursday, April 2, 2009 - link
Calibrated. As best as I can tell, there's no truly reliable way of testing the color accuracy without calibrating. I tried to do it in the past, but I became suspect of my results. Besides, if you need accurate colors there's generally no way around hardware calibration utilities.DigitalFreak - Thursday, April 2, 2009 - link

Truth in advertising? :-DLingyis - Monday, May 3, 2010 - link
bad news--i was just gonna get one of these babies and Dell told me Studio XPS 16 no longer comes with an RGB LED option.i want a good laptop display--i'm deciding between the Studio XPS with a regular WLED vs the Precision M4500. The precision M6500 appears to have RGB LED but it's 17 inches which is too big.
so what to go for--the RGBLED-less Studio XPS or the Precision M4500?
