Samsung Series 7 Battery Life

Samsung is using an 8-cell, ~80Wh integrated battery in the 17.3” Series 7, and similar to Dell’s XPS 15 and the MacBook Pro 15 it’s not user replaceable. We calibrated the LCD to 50% 100 nits (43% brightness, or three steps down from max) for our battery testing. Here are the results for our standardized battery life testing.

Battery Life - Idle

Battery Life - Internet

Battery Life - H.264 Playback

Battery Life Normalized - Idle

Battery Life Normalized - Internet

Battery Life Normalized - H.264

It’s not too surprising to see the Series 7 perform very well, given the high capacity battery. Maximum battery life is just over seven hours, Internet battery life is six hours, and H.264 playback lasts 4.5 hours. We’ve noted in the past that laptops with higher resolution displays do worse in our video playback test, and that’s the case here as well—there are more pixels to calculate and update every frame of the video. While that means lower resolution displays win out in this test, we’d much rather have the higher resolution display.

Looking at the big picture (literally), battery life is generally ahead of everything except for Ultrabooks/ultraportables and AMD’s Trinity, which should be sufficient for most users. Of course, normalized battery life shows that the larger LCD is definitely taking its toll, as the Series 7 drops into the bottom four of the charts. Even so, it’s still the best result we’ve seen from a retail 17.3”-screen notebook.

    I know it's probably not as sleek or thin, but then neither is the ASUS N56VZ that you suggested for the "technology addict" or "gamer." I want a laptop that acts as mobile workstation by day and gaming laptop by night. What do you think of the lenovo Y580? Right now they have a model with a 1080p screen for under $1k . Pop in a 128GB msata SSD for an additional $150 or so and it seems like that's quite a compelling choice. I'd love to see an in depth review of that machine.

    Honestly, it's extremely similar to the ASUS N56VZ but with a couple minor differences. First is that the ASUS appears to get slightly better battery life, which is related to the second aspect: the Y580 comes with a GTX 660M GPU. It's only a slight clock speed increase from the GT 650M, and I'm not sure I'd call the 660M worthy of the GTX branding, but it's still faster.

    The keyboard on the Y580 looks nearly identical to the ASUS layout, they both come with Blu-ray, and most of the specs are about the same elsewhere. It's really just a preference for the LCD (ASUS has a matte 1080p display whereas the Lenovo is glossy), plus the ASUS is cheaper, and lastly ASUS isn't afraid to send us review units so I've actually had hands-on time with the N56VZ. I should also mention that Lenovo uses a 5400RPM HDD with a 32GB SSD cache, where ASUS uses a 7200RPM HDD with no cache. If you're going to replace the HDD with an SSD, there's not much point in having the 32GB mSATA SSD hanging around IMO (or as you note, you could look for an mSATA SSD).

    Unfortunately my retailers of choice do not offer a N56VZ in the US with a 7200RPM hard drive. Also, the N56VZ uses a GT650 with DDR3 memory which a trustworthy site has informed me will not perform as well as the DDR5 version (although they did point out the boost in clock frequency will compensate the slower memory somewhat). Lenovo does offer a variant of the Y580 with a 500GB 7200RPM drive and no mSATA SSD so my plan is to just do a fresh install on a 128GB mSATA that I pick up from crucial. Sounds like a driver installation nightmare waiting to happen but who knows, it could work.

    I'm not sure I'd buy a Lenovo after I found a survey they did about matte vs glossy displays.... 6 years ago. I guess it didn't matter that 86% of the participants voted for matte and spitted on glossy. They removed the survey from their forums... probably from shame.

    I mean who cares what the customer wants.

    One problem with that Ars article is this line: "There are some advantages to having a glossy screen: in particular, outdoor visibility is greatly increased." WTF? Outdoor visibility is increased by glossy? Where are they using such screens "outdoors"? Because all I get on glossy screens outside is a nice reflection of my face. :-\

    It should never throttle on a brand new laptop - if it gets that hot then the cooling is insufficient. This means inconsistent performance, noisy cooling as the fan is maxed out, and the cpu/gpu dying young due to being run so hot all the time.

    Remember that laptop is new, the fan is clean, it's as good as it will get. Use it for a few months and the cooling system will have dust in it and be significantly less efficient - the laptop will be continuously throttling. Sure you can clean it out, but most people don't want to have to clean out the fans every month to keep their machine usable.
  • JarredWalton - Thursday, August 16, 2012 - link

    I'm not sure how you consider about three pages worth of discussion on throttling and a conclusion that says "gamers and enthusiasts should probably look elsewhere because of the throttling issues" as being accepting. There are many people who would only occasionally game, and if you want a nice looking notebook with a good display and keyboard there aren't that many options. Certainly the Series 7 looks nicer than the ASUS and Lenovo laptops mentioned elsewhere, with a better keyboard layout as well. For everyday use, I'd take the Samsung over the other two, but I'd do it knowing that gaming/graphics are going to have thermal issues at times. That means you're spending about $250 on hardware you won't use much, but people have done worse things.

    I would think the issue is more longevity rather than performance.

    Remember, most people don't even think to blow out fans/grilles with air, let alone pull the thing apart and clean it properly. Add dust to something that can't cool itself properly to start with = problems.

    Or am I just old-fashioned in wondering what the product's use will be like in 1 or 2 years' time. All I'm supposed to consider is looks and price and maybe a few spec tags like "i7" and "8gb ram". Ugh I hate 'consumers'.

    The temperature graphs have MHz for the vertical axis instead of degrees.
  • JarredWalton - Thursday, August 16, 2012 - link

    Ugh... I hate it when I do things like that. These are all manually created charts as well (for the clocks/temps), so I have to go into Excel, edit the chart, then take a screen capture, paste into Photoshop, crop, save, and upload the result to our CMS engine. What a pain! Anyway, the charts are all fixed now (I hope!)
