Studio 14 Battery Life

So far, our review unit has shown us solid performance in applications and about the best performance we could ask for in gaming (given the lousy options presented), but an increasingly important metric these days is battery life. We expect good things out of the Studio 14: the high capacity 6-cell, 56Wh battery should be able to get us at least four hours of useful life out of the notebook.

Relative Battery Life

Getting close to three hours of movie playback time is pretty reasonable; in fact it starts scraping under machines with integrated graphics and bigger batteries. Under internet usage it gets even better, with the Studio 14 pulling nearly five hours of useful life at a comfortable brightness. Dell's done their homework here: the battery life on our Studio 14 is miles ahead of their last generation. The exception to that statement is x264 playback, where the old 9400M IGP of the 14z surpasses the new 14, though it had a larger battery. Note that on a per Wh metric, the 14z scored 2.92 compared to 2.86 on the 14, so it's pretty close even in that case. The dedicated graphics may be extremely low-powered but the chip still draws more power than the integrated graphics would have, and there's no indication that the Studio 14 is switching between the two.

Given the excellent running time from the stock 6-cell battery, we feel comfortable recommending users who need more than five hours of life opting for the 9-cell. Dell's site suggests that extended battery can last for up to eight hours and thirty-five minutes (how delightfully specific), and it's reasonable to assume they aren't far off the mark.

    It would be nice to post the basic specs and the upgrades and their costs. This will help us understand where the extra money is going from the basic price...

    Honestly, Dell changes system configurations and options on their site more often than most people change underwear. We got this notebook less than a month ago and it's already obsolete in certain ways.

    "After all, the Xbox 360 is nearly five years old, and 720p is the target for that console." Even the latest and greatest and slimmest xbox 360 still burns over 80 watts playing a game. I'm sure a notebook would produce great gaming benchmarks if it pulled that much power.

    The Xbox 360 revisions haven't had the chance to really change things up. Yes, they did a process technology shrink, but they still have to maintain 100% compatibility with the original Xbox 360 so there are limitations to what they can do. I also don't think the CPU/GPU in the Xbox 360 gets the same level of power friendly optimizations that laptop parts get, but then the manufacturers aren't very forthcoming about console architectures and such.

    Anyway, look at the 5650 and 335M; they consume around 20W max on the 5650 (15W for the 5470... Dell really couldn't get 5W extra out of the chassis?), and 28W max on the 335M. Idle power draw is down around 5W on both. At 100% load, such a laptop would be about 20W less than the 360, but that's well within reason. If MS binned 360 CPUs/GPUs for minimum power draw like mobile parts, they could easily get below 80W.

    It would be more interesting to see how this compares to something like a Thinkpad?

    Or any other laptop for that matter...

    Dear College Students,
    You don't want this laptop, You don't want a glossy display because you want to be able to go outside and study once in a while. Also , you want a nice matte display, with a nice, high resolution, say 1920x1080 or hell even 1600x900 so that you are more productive in your work and can get better grades. This is not the laptop for you. If you can't afford a better, new business class laptop, look for a used one (say one or two years old) with a good display and just buy a new battery. You'll be much happier. I would be anyway.

    It depends what sort of work you're doing. If all you need to do is write papers in Word, screen resolution is generally a non-issue. You look at one or two paragraphs at a time and go from there. If on the other hand you want to do video and photo editing, resolution becomes far more important.

    The glossy stuff is a different matter of course. I wish there were non-business laptops with matte LCDs still. But, buying used is a bad idea IMO. Laptops don't usually last more than 4 years of constant use, batteries stop holding a charge after 1-2 years, hinges wear out, and battery life is something that has just as much impact on usability for college campuses as the screen. Take a 15.6" LCD with a matte display and you're probably looking at 2-3 hours battery life in most cases. If it's used, more like 1 hour if you're lucky, unless you spend $100 on a new battery.

    He addressed the battery issue by saying to buy a new one.

    I disagree that resolution is ever a non-issue. Who wants to only be able to see 2 paragraphs at once? And if you do any formatting or visual organization to the paper, you will want to see each page at once. That doesn't work with 768.

    ...so I avoid all laptops with ATI graphics.
  • semo - Thursday, August 19, 2010 - link

    when you plug in a microphone or headset through linein, do you have to change any driver settings and are those settings remembered.

    I have a studio 1557 that asks me to confirm linein settings every time i plug in a headset and even between restarts. My other laptop will start using an external mic even in the middle of a conversation. Im sending it back and if they cant fix i will be looking for a replacement
