Battery Life and Thermals
With the performance aspects out of the way, let's turn to battery life. I have to say, I've run more battery tests on the Acer S7 than perhaps on any other laptop in recent history. It's not that it needed extra testing, but as the first Windows 8 laptop in our labs I wanted to look at changing some of the tests. We discussed things among the various editors, and I worked to come up with some redesigned, hopefully better battery life tests.
First on the chopping block is the idle battery life test; rarely do people use workloads that are so light that it's meaningful to look at pure idle battery life, and going to the extreme of muting the volume and turning off WiFi is more than most are willing to do. We've decided to move to our Internet test as the baseline measurement, since it's representative of a moderate workload that conceivably might be used while running a laptop on battery power. With moderate Internet surfing (we load four pages every minute, simulating time for reading) as our light workload, for our heavy workload we crank up the frequency of page loads (the same pages, only loading every 10 seconds now) and add in playback of a bunch of 128kbps MP3 audio files. Finally, for our heavy workload we keep the Internet portion of the moderate testing but add in looped playback of a 1080p H.264 encoded video and have a constant 1Mbps download running from a local server.
With this being the first laptop to use our new Windows 8 test suite, we're in a bit of a state of flux so I've run both the new battery tests along with the old Windows 7 era tests (only with IE10 instead of IE8/9). I also ran a few other battery life tests just for reference: the three PowerMark tests. We're a little hesitant to use PowerMark as a standard, simply because it's limited to Windows platforms and has the potential to encourage optimizations for a benchmark as opposed to general optimizations; as you'll see, however, there's plenty of overlap between our tests and the results from PowerMark.
Starting with our older 2012 battery benchmarks, the Aspire S7 has a pretty poor showing. The 35Wh battery is the same capacity as the previous generation Aspire S5, and yet battery life is down substantially in all three tests. Whatever Acer (or Microsoft) has done in the past six months has not been helpful in this area. Normalizing for battery capacity does improve the situation a bit, but where it’s enough to move Acer past the two Toshiba Ultrabooks and the HP Envy 14, that’s not saying a lot—and higher battery capacities do count for something. The bottom line is that best-case, we were able to get just over five hours of running time out of the Aspire S7. Let’s look at some other results.
| Acer Aspire S7 Additional Battery Tests | ||
| Battery Test |
Run Time (Minutes) |
Normalized (Min/Wh) |
| AnandTech 2013 Light | 240 | 6.86 |
| AnandTech 2013 Medium | 173 | 4.94 |
| AnandTech 2013 Heavy | 137 | 3.91 |
| PowerMark Productivity | 255 | 7.29 |
| PowerMark Balanced | 201 | 5.75 |
| PowerMark Multimedia | 172 | 4.91 |
Note that in the above tests, we’re using 200 nits for our 2013 test suite while PowerMark specifies 110 nits as their desired brightness level. Our Light test result is down 21 minutes from our previous Internet test result, most likely due to the increased LCD brightness. Elsewhere, our new Medium test drops us below the three hour mark, and our Heavy test is getting close to lasting only two hours. It’s not really realistic to expect a full day of use from a laptop when you’re going full-tilt the whole time, but considering the CPU load is only around 10-35% even in our Heavy test, we’re not pushing things that hard.

Why stop there, make it an even 1" then you could have 2 memory slots and a removable hard drive. Or even better make it 1.5" and have a huge removable battery, an optical drive and a dedicated GPU! No make it 2" and 17" screen then you can have a full sized keyboard top of the range graphics high end CPU tons of storage and neon lights on the top of the shiny plastic case!!1!Not really aimed at you, just all the people who like there £300 lappy and can not possibly imagine a world where other people want different things.

you totally did not comprehend what i meantblue_urban_sky - Wednesday, January 9, 2013 - link
You can't see the point of making the thinest laptop.You think they should have made it fatter and increased the stats.
You justify this by saying people could not tell the difference without a ruler.
You fail to understand that increasing the height from 0.5"->0.7" is a 40% increase in volume where "overall volume are what matters the most" .

You completely failed to grasp his point. Making the thinnest laptop possible doesn't make any sense if it adds too much to the price. If it compromises too many variables, then it's obviously more logical to make a slightly thicker device. All you're doing is reconstructing his statements into a straw man. You're also using percentages to make your argument sound stronger, but nobody cares about percentages. We're talking about actual thickness here. You know, real world stuff. Nice try.blue_urban_sky - Friday, January 11, 2013 - link
Joy the straw man miss used again. They were to illustrate that I understood their position thus arguing against "you totally did not comprehend what i meant".Shall we dissect your truism :-
"Making the thinnest laptop possible doesn't make any sense if it adds too much to the price"
Is that too much according to you or is it a standardised figure? So your argument can be read as
"Making the thinnest laptop possible makes sense if it doesn't add too much to the price"
And:-
"If it compromises too many variables, then it's obviously more logical to make a slightly thicker device."
Compromises on variables that you hold above others. So this could be rearranged to
"If it doesn't compromise too many variables, then it's obviously more logical to make a thinner device."
Lastly
"but nobody cares about percentages. We're talking about actual thickness here. You know, real world stuff."
I commend that you went to the trouble of asking everyone (out of interest did you insult them as well?). Ahh I didn't realise we were talking about 'actual' thickness!
You're also using 'actual' to make your argument sound stronger (sry couldn't resist).
The real world works by iterative development things happen in small increments.

I'd even argue ergonomics are now more important than overall bulk. Modern laptops just aren't that thick or heavy anymore, so I don't understand why some people are claiming that a pound here or a half-inch there are worth the ridiculous price premium. I also don't understand what a touchscreen has to do with being light and thin, but I digress.I realized how much I appreciate the 15" size when I tried using an 11" netbook for an extended period of time. The keyboard was just far too cramped. 10 inches might be a good size for a tablet, but when I want keys, I'd rather give up some size and thickness for better keys and room for my hands to be comfortable. Having the extra screen space of a slightly larger chassis is a bonus, and coming from an 11" chassis, there's no comparison.
I've got an old PII laptop that until recently I would occasionally use. That thing probably weighs about 9 or 10 pounds. It's nicely built, and even has a matte screen, but it does get heavy to hold. I can't help but think that the 5-and-a-half pound notebook I'm using right now is pretty darn light. It's lighter than the 6-lb bowling ball I used to throw when I was 8. It's also got a bigger screen and a much nicer keyboard than this Acer, and cost about a fourth of the price.
Clearly, these ultrabooks are toys for suckers who think their social status depends on what kind of gadgets they own.

Agreed. Well said.blue_urban_sky - Friday, January 11, 2013 - link
*sigh* You were doing well right up to your last paragraph.B-

Jarred,Thanks for your review. And special extra thanks for emphasizing productivity features and ergonomics for people who actually work.
I am a professional photographer and full-time businessman. I live in Photoshop, Excel, Word, eMail, and web research. That is what I must do and what I enjoy doing. I never play games.
Your comments on the action and utility of the keyboard and its layout are crucial. Also the touchpad. The keyboard and its shortcuts, along with the touchpad is where most true workers live. We can get things done 10x faster with these interfaces than with a touchscreen.
Thank you for continuing to harp on these issues, as they are critical. Yes, a pretty face is nice to look at, but the real beauty of a computer is in its function.
As for price, I am by no means rich, but I am more than willing to pay for an excellent productivity tool. If a laptop must cost $1100 or 1200 or 1300 to have essential features such as a decent IPS panel and a decent backlit keyboard and a decent touchpad, then so be it. But if you take away the backlit keyboard to save $20 or $50 or whatever, then the laptop to me becomes useless.
There are tons of functionally compromised laptops for the masses that are hobbled by pricepoint. But it is not right to reduce those of us who must work for a living to the lowest common denominator.
Kudos to Acer for stepping up with an IPS screen. I would be MORE than willing to pay $1300 for this tool if Acer had bothered to get the little things right - excellent backlit keyboard with great layout; fantastic (rather than mediocre) touchpad; decently calibrated IPS panel. And I'd much rather pay $1400-$1500 to have these things RIGHT, than $1200-$1300 and have them not quite right.
Thanks again, Jarred, for your great reviews.
Thanks, Acer, for moving in the right direction. Please don't stop short of the goal.

I'm a huge tech dork as you'd expect considering I'm reading AnandTech. So when my wife decided to get this laptop, I gave her a quick Windows 8 tutorial as if I was teaching an alternate version of myself how to use it."Just click the desktop"
"Just use the trackpad, why use touch?"
"You can mostly ignore the Metro stuff, that's just meant for tablets"
Cut to my surprise when she basically ignores all that advice, and absolutely falls in love with the laptop using touch almost all the time, sticking in Metro apps almost all the time, and barely ever seeing the Desktop.
When the laptop is sitting on a desk, she's always resting on her elbows anyway, so reaching toward the screen is natural. When the laptop is sitting on her lap, her thumbs are right there at the screen, so it's perfectly natural to reach out and touch it. Metro apps meet most of her needs for web browsing, playing games, and chatting with friends, so she really only uses the Desktop for Office.
The keyboard is a bit annoying to her, but everything else about the laptop is nearly perfect. Even the battery life, considering that she's coming from a Vista-era laptop from 5-6 years ago that was upgraded to Windows 7.
After observing her learn to use Windows 8 and eventually fall in love with it and this laptop, it really made me rethink my expectations for the OS in general. Maybe the tech press has it wrong because they're approaching it from expectations that normal people simply don't care about?
