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.

    "Dell XPS 15 results in yellow"

    The yellow bars show the Aver V3 and not the Dell. The Dell laptop has the standard ark blue colour.

    Fixed, thanks.

    I own a 15 inch version of the previous generation, these are excellent machines, but yes, an enthusiast will not be satisfied with it as-is. I ended up throwing in a 512 Gb SSD and an Intel A/B/G WiFi card. Getting into these is NOT easy, so I'm not looking forward to any equipment failures, but these things are solid, compact, quiet, with a good layout, blowing all the exhaust to the BACK, as it should be. And I have to say the keyboard is the best one short of a Thinkpad that I've ever used.

    Never knock sleek and thin, particularly if you have to travel with the thing. I went from an Asus N53SV to this, the Asus was a real pain anywhere except at home on my desk, and on the occasional hotel desk (took up a lot of room there). The Series7, even the 17 inch, is a much more desirable travel companion.

    Samsung just needs to make service easier somehow.

    Right now i am just waiting for a 17inch laptop with ips panel, that actually offers nvidia 680m in it, instead of those insanely overpriced quadro graphic cards. along with the Maximus technology.

    I have an Alienware M17x R3. I bought primarily for the keyboard (best in class, in my opinion) and the screen secondarily, for the build quality tertiary. How does the Samsung stack up against the M17x R3 keyboard? All the keyboards I used before the Alienware caused pain in my fingers after five minutes of use programming. The two sore points for me are where I interact most with the machine - the keyboard (fingers/wrist/hand) and the screen (eyes).

    Dustin did the M17x reviews, so I'm not sure personally how they compare. The Alienware is more of a traditional style key shape as opposed to chiclet, though, so I could definitely understand people preferring Alienware's keyboard. Interestingly, it's also missing the "context key" -- am I like the only person that uses that key? Also, anyone know if it's possible to remap something like right Alt to the context key? Might make me happier.

    In general, I prefer the size and weight of the Samsung to the M17x, and I think Samsung has a better display (matte for one). Alienware obviously has more GPU performance and better cooling, as it doesn't have as much difficulty with throttling under maximum load (AFAIK -- correct me if I'm wrong). Cost is also clearly in favor of Samsung, but if you play games I'd say it's an easy choice to go with Alienware. For those that just want a good keyboard, it's a personal opinion thing so you'd probably have to try both laptops out if possible. I still want to play with an MSI GT7 series with the Cherry MX switches (I think that's the one, right?) just to see how it feels.

    I have the 15" version, love it for the most part. The one thing that really bugs me is the trackpad. I constantly have issues with it misinterpreting a quick lift of the finger and move back to center as a left click, as when scrolling or going from one side of the screen to the other, something I haven't encountered with any other trackpad I've used. It also often doesn't manage a tap-to-doubleclick, instead selecting and then dragging things. Yes, I could push harder for the physical button click, but that just isn't very intuitive - and the pressure required often results in inadvertent movement of the cursor anyway.

    (I was also annoyed because they gave me inaccurate information about the hard drive; I was looking at two similar-but-slightly-different model numbers at two different retailers, one advertising 750 GB 7,200 RPM hard drive, the other advertising 1 TB HD. Contacted Samsung to find out how fast the 1 TB drive was, as the retailer couldn't tell me, and was assured that it was also 7,200 RPM after a very long wait for him to look up information. Turns out it's not, it is a slower 5,400 RPM drive. I'd have preferred less space w/ a faster drive, but oh well - some day I'll stick a large SSD in. Only after getting it did it occur to me to look at HDs offered separately, and it turned out no one was selling 7,200 RPM 1 TB laptop drives - should have clued me in).

    Anand said you'd be handling the UX31A review, Jarred. Any idea when that'll be out?
  • JarredWalton - Friday, August 17, 2012 - link

    Next up on my hot list. :-) Short story: it's the best 13.3" Ultrabook, but it's still an Ultrabook. Keyboard key travel is better than any other UB I've used/tested, and the IPS display is obviously the huge selling point. Build quality is good as well. Only real issue is the price, battery life is decent but not exceptional, and you're still getting basically Ultrabook levels of performance -- fine for most apps, but not for serious number crunching or gaming.

    Thanks, good to know! I've got a desktop for gaming and other heavy usage, so performance isn't too much of an issue. Build quality, portability, and that wonderful screen were my main interests.
