HP Mini 311 — Battery Life

We run many scenarios for our battery life tests. Most netbooks don't include optical drives, but since we had the external Blu-ray drive we were able to run our DVD and Blu-ray tests… sort of. We couldn't get DVD playback to work in Windows Media Player (or Media Player Classic - Home Cinema) due to "copy protection errors" (aka DRM rearing its ugly head — probably some codec or software we installed), but DVD playback worked fine with the included Arcsoft TotalMedia Theater 3.

TMT3 also supports a DVD up-sampling technology dubbed SimHD that's supposed to improve DVDs to "HD quality". Don't let that fool you! It's essentially a sharpening (sometimes over-sharpening) filter applied to every frame from the movie. It can look good in some scenes while adding noise to others, but some users might prefer the experience. SimHD isn't without its drawbacks, as it resulted in significantly lower battery life.

As a point of reference we ran the DVD playback tests with files copied to the HDD as well as from the external DVD; as you might expect, spinning a disc results in lower battery life — worse even than SimHD from the HDD. Honestly, DVD playback is so pre-2005, and this is the last you'll see of it in our testing of laptops. Rip a disc to your HDD and you won't have to worry about scratches or DRM issues, and you'll get better battery life to boot — a win-win-win scenario. Don't tell the MPAA and Media Conglomerate lawyers….

In addition to the above, we tested DivX HD, x264, Internet, Idle and even Gaming battery life. GPU decode acceleration is used where possible (and it's required for the Blu-ray test). DivX is also supported natively within Windows Media Player now, and a quick sanity check shows that it improved battery life slightly compared to decoding within MPC-HC (using ffdshow).

Relative Battery Life

The battery life results are rather interesting. You can now get 9400M graphics performance (slightly slower than 9300M since it shares system memory bandwidth) with battery life that's at least close to some GMA 950 netbooks. The Mini 311 trades blows with the M1022 in our battery life tests, and it's very close to the old ASUS N10JC running in GMA 950 mode. In 9300M mode the Mini 311 offers clearly superior battery life compared to the N10JC. Unfortunately, that's only looking at half the picture.

The ASUS 1005HA still offers significantly better battery life in all tasks. The closest result is in x264 decoding, where the ION LE can help out, and the 1005HA still offers 40% better battery life. In other tests, the gap is as high as 80%, with the average advantage being closer to 60%. The 1005HA does have a larger batter (63Wh vs. 53Wh), though, so the real power advantage is 17% to 50%, depending on task.

As a whole, battery is generally good, but clearly certain tasks put a major load on the system. Blu-ray is still a killer, even with GPU acceleration, resulting in just over two hours of battery life. We don't have a chart (since we don't have results from most of the other laptops), but simulated gaming battery life (looping 3DMark at native resolution) lasted 160 minutes, actually surpassing Blu-ray playback time. However, as we discussed on the gaming performance page, that result should be taken with context: despite the ION graphics being plenty fast for low detail gaming, the Atom CPU just can't manage to run the majority of current 3D games. You'll want to stick to 2D games (a la Popcap) or titles from the early Pentium 4 era to get acceptable performance on the Mini 311.

    I have a Timeline 1810 for review, so I actually have practical hands-on experience. Plus, when you consider the RAM upgrade on the 311, and a few other sundry extras, you quickly get a more realistic base price of $450 to $500.

    At that point, comparisons with anything from the 1410 (and the Gateway EC 1435u I mentioned) through the $650 Timeline/EC models are all valid. Unfortunately, I don't have the $400 laptops in for review. I can come up with a fairly reasonable idea of how they'll perform, however, and the Celeron SU2300 is by far the best option for a small netbook right now.

    Do you guys run a default calibration on all of the displays before you test them or are those numbers OOTB?
  • JarredWalton - Sunday, November 22, 2009 - link

    Those numbers are using ColorEyes Display Pro to calibrate the LCDs. I have tried in the past to come up with an "out of box" result, and either the LCDs are all horrific (typically Delta E will average around 12 to 15), or I'm not doing the test properly. Without a way to be 100% sure what was going on, I decided to just stop doing those tests.

    Ultimately, I think most users will adapt to however a display looks, unless they're really serious about color quality. When we're looking at netbooks, I think the vast majority of users never really pay attention to the LCDs. Obviously, I do pay some attention, but unless a display is really good I'm not going to spend much time on that area. Right now, most of the laptop LCDs are junk.

    Amen to that. I find it incredible that vendors are selling 15" displays with only 1366x768 resolution. (While these 11" netbooks have the same resolution.) When I buy a 50% larger screen, I expect 50% more workspace, not 50% larger pixels. WTF...

    I own two HP 311 Mini's (one custom built and other 1037NR from VZW)and one HP 1151NR from VZW and can say the keyboard and touchpad placement were compromised on the 311s from older versions. The smooth keys and angle due to 6 cell make it challenging to type on than the 1151's matte finish and flat bottom. Plus, the left/right mouse buttons on the bottom make it tough to click compared to 1151.

    However, compared to the older 1151 there are many advantages (screen size, larger stock battery and RAM, easy access to internals) and the reason why I picked up a second HP 311. The HP 1151 is being traded in tomorrow.

    jarred, you act like an atom limits the performance/experience even in simple day to day applications. i have to admit, i had similar gripes before my gf got her asus 1005hah, but now i learned, that this standard atom-netbook is delivering quite well in everyday tasks.

    (of course) i had the pleasure to set this thing up installing software etc and i also did a lot of web-browsing and not even in this new youtube 1080p video-sample (fullscreen) i had slow-downs while bettery life was exceptional (8-10h) because i could use the super-power-save mode.

    boot and hibernate etc also were much faster than on our standard notebooks (dell vostro c2d).

    so while atom is extremely slow in raw numbers compared to other cpus, the everyday tasks of the average user dont suffer from this limitation.

    just want to make things clear ;) otherwise excellent review, thanks!

    Not to mention that for more compute intensive operations (other than games and multimedia authoring) there's always VNC or remote desktop. Works well for a bunch of engineering and scientific software.

    Netbook+desktop is a very good alternative to a single power notebook, and often comes in cheaper and more portable to boot.

    I bought this dv6-1154tx for INR 67,000 (approx. US $1400) when I joined uni this year. Should have got a $1000 desktop and a $400 netbook instead. Now I'm stuck with this notebook for another couple years or so at least.
  • Lonyo - Sunday, November 22, 2009 - link

    I got an Asus 751h with the slower 1.33GHz processor, and apart from being sluggish on Youtube and some other unnecessarily intensive sites, for what I actually use it for, writing papers in the library, it's perfectly functional.
    Most of the time is spent checking websites for resources, looking at pdfs and using Word 07, and for all those tasks it's fine.

    Sure I can't encode stuff, but who would dream of doing that?
  • JarredWalton - Sunday, November 22, 2009 - link

    But have either of you tried something like a Timeline 1810? I have, and I can tell you that the experience is better than Atom -- quite a bit better in many instances. It's not just about raw, CPU intensive performance; the 1810 boots faster (marginally) and loads applications faster. Trying to open a dialog while a video is decoding as one example is horrible on Atom -- better to pause the video first.

    Basically, Atom *can* do what you need, but so can just about any other CPU currently out there.
