Sony Touts 25 Hour Battery Life For Haswell-Equipped Vaio Pro 154

An anonymous reader writes "Sony claims that both the new 11.6-inch and 13.3-inch models of its Haswell-equipped Vaio Pro ultrabooks are the world's lightest. The 11.6-inch model weighs in at 1.9lb (0.87k , where as the 13.3-incher is a little heavier at just 2.33lb (1.06kg). But it's the battery life on offer here that really makes the new Pros stand out. The 11.6-inch Vaio Pro offers 11 hours of battery life as standard, while the 13.3-inch achieves 8 hours. However, Sony is also offering a sheet battery you can connect to the base of the ultrabooks. On the 13.3-inch Pro that increases battery life to 18 hours, but on the 11.6-inch you get a true day-long amount of juice with 25 hours of battery life claimed."

  • "25 hours of battery life claimed." So in reality it'll be about maybe 4 hours of actual use, unless Sony's reality is screen dimmed until you can just barely make out shapes and just staring at it for 25 hours. Yep, that sounds about right for Sony Reality.

      Imagine if automakers got together and started measuring the gas mileage of new cars with a cool test of their own making—one in which the cars were rolling downhill with their engines idling. Suddenly you'd have some pretty amazing claims: Why, that three-ton SUV gets 300 miles per gallon! This subcompact gets 500! In tiny print at the bottom of the window sticker you'd find a disclaimer saying that, well, um, you know, your mileage may vary.

      Crazy, right? Yet that's more or less what's happening with laptop computers and their battery lives. Right now, I'm looking at a Best Buy flier touting a $599 Dell laptop that gets "up to 5 hours and 40 minutes of battery life." Down in the fine print comes a disclaimer explaining that "battery life will vary" based on a bunch of factors. Translation: you ain't gonna get five hours and 40 minutes, bub. Not ever. Not even close.

      From a 2009 article excoriating the practice. [thedailybeast.com]

      A computer that can function for ten hours is quite useful, but a twenty-five hour battery life is only marginally more so.

        ...then consider the life of the laptop... a year from now when the 24 hour battery is back down to a 10 hour battery and a 10 hour battery down to 5 or less. considering that batteries degrade generally in line with their full lifecycle abuse, the 24 hour battery will degrade on a better curve for the usage/abuse patterns.

        • Nothing in the ad copy suggests that the battery is glued in. If battery life beyond your threshold is compelling, you'll replace it. If it's not, you won't.

            Not having to replace the battery in a year is a feature.

            • But you'd still have to buy the external battery pack. Which would you rather have, a lightweight computer that lasts for 10 hours because you replaced the main battery, or a somewhat heavier computer that lasts for 10 hours because you've successfully run both batteries halfway into the ground? The cost is the same.

        • While a battery will degrade with time and accruing cycles, it's nowhere near as extreme as you're saying. Sure, if you're charging and discharging at 60+W and really abusing the battery by rapid-charging it right after it's been completely discharged (still warm) or other no-nos, you might see that rapid a drop in capacity, but these devices hardly draw 10W in normal usage scenarios. The batteries shouldn't lose much capacity at all during their first few hundred cycles...

      • While I do agree with you in principle, there are certain use cases in which "idling" very much applies - with the exception of the display backlight. Reading Slashdot, for instance... or office work... or reading a PDF... so the claims aren't always as far-fetched as they seem. Hell, I regularly get 12 hours of battery life out of my Thinkpad, and that's rated for something like 13 or 14 hours IIRC, so pretty much right on the money since I use mid-high display brightness instead of dimmed.

      The sheet battery weighs only 290 g, [sony.co.uk]

      • It's rated for 36 Watt-hours. Even if that's per cell for the four cells in the battery, it'd have to be running in a heck of a low power mode to get the run time they're describing.

        • It is not per-cell (at that weight it would be a much more notable breakthrough if it was).
          So assuming the screen, backlight, memory, and SSD use no power at all. Then you can use 15% of your CPU/GPU for 14 hours - yay marketing!
          In fact the USB 3 charging port alone would drain the main and external batteries in 9 hours with the laptop in full sleep.

    • Absolutely correct. What is needed here is a real power benchmark. A numerical score that incorporates weight, screen size, performance, and battery life. Perhaps something as simple as:

      Score = Battery Time * Screen Size * Performance Benchmark Score / Weight

      Doubling the weight to double the battery time would result in no net gain under this kind of formula. However, using a more efficient battery or optimizing the computer to use the battery time better would result in higher scores.
      • by Nemyst ( 1383049 )
        Doubling the battery weight won't double the weight of the laptop, so your score would in fact go up with that technique. In fact, your score is biased towards things that maximize battery weight, because it's linearly proportional to battery time, thus making it most efficient when the weight of everything else is negligible compared to that of the battery.
      • I agree with you that some benchmarking system would help, maybe "flops per amp-hour" or something, but your formula would lead to manufacturers gaming the system for higher scores and ignoring that people want different devices for different needs.

        For example, a smartphone may have less screen size and performance than a tablet but not have an equal return in battery time or weight reduction, resulting in a lower score, and still may be "better" for someone that can't fit a tablet in their pocket.
