Benchmark Results: Battery Life
It isn't surprising to see the Asus 1215N lead the pack. It has an extra-dense battery compared to the 1215T and benefits from Nvidia's Optimus technology. We should point out, though, that roughly one-third of our general use workload centers on multimedia playback. The other two-thirds includes office productivity (Web browsing, typing, and sending emails).
Our “Typical System Use Power” (TSUP) is similar to processor TDP, except that we are measuring power consumption of the entire system under our workload. Remember this is on the DC side, so it is unlike the power consumption numbers we use in other reviews. This factors out PSU inefficiency.
Charging times are a double-edged sword. Ideally, you want a nice slow charge so that your battery lasts more than a few hundred charges. Fast charge times keep you away from the wall socket longer, but in the long run they cut down on the battery's useful life. Manufacturers utilize a variety of charging schemes to strike a balance, which is why we are showing two benchmarks. Usually, the rate of charge starts to slow down somewhere in the 80% to 95% capacity range. That's why the charging time from 0% to 10% is faster than 90% to 100%.

one-shot Why get this outdated tech when more powerful Sandy Bridge based laptops are already out and more with even better battery life are on the horizon within the next few months. Here is a link from Anandtech that shows a i7 2820QM 4Core/8Thread CPU getting almost 7 hours of battery life (416 minutes) surfing the web with heavy flash.Reply

These CULV were great a year ago, but not anymore. This is old tech and purchasing any of these is a poor use of your money if battery life and performance are what you are after. If you want shorter battery life and weaker performance, then by all means this is for you. Sigh... -
acku We will have our Sandy Bridge mobile up story up shortly, but that is a i7-2820M. It is meant for DTRs. CULVs are a different beast. Brazos is more applicable comparison if you read our conclusion.Reply
And "heavy flash" is somewhat of a misnomer. Its still single-threaded. It doesn't matter what video you happen to be playing. And if you read our Flash article then you know H.264 Flash video has very little overhead on current GPUs (including Sandy Bridge), because they all use hardware decoders. This is going to naturally translate into more battery life. This doesn't just go for Intel. It goes for Ion2, Nile, etc...

runswindows95 That RLU benchmark is a really useful benchmark! I for one would buy a netbook or any system just to do word processing, the internet, and mp3's all day. You should also include it when comparing lower-end desktops as well because not everyone buys a computer to run high-end graphics all day. It really made me look at these netbooks better, and I can make a better decision based off that one benchmark alone.Reply -

Honestly, that is probably the first compliment we have received on it. But I'm glad to hear you like it. Feel free to drop suggestions for improving it or possible permanent names.
I'm glad at least my many hours of programming weren't useless. But we plan to use it in our (many) upcoming mobile system reviews as well. -
braneman I think the appeal of these netbooks is more if you have to carry them around with you, also they are 500$ cheaper, smaller, and probably several pounds lighter than a sandy bridge notebook, trust me if you have to carry it around with books you will notice the difference between this and a 15-17 inch laptop.Reply -
super_tycoon inaphasiaHow did you guys update the Ion2 drivers on the 1215n?you should try using nvidia's drivers from their website, for a long time I couldn't get any installer to work and had to resort to windows update (I reinstalled windows to x64 ultimate). However, I tried again with the 266.35 installer and that worked perfectly, even with the gpu 'off'.Reply
I just want to add that if you're going to rip open your 1215n, swap the wifi card. I replaced the stock bs with an intel 6200 (the 1215n only has one antenna, so overkill, yes) and it's amazing. A situation where a cheap abs case is actually beneficial.
I also don't recommend upgrading the hdd to an ssd. They're expensive, and the platform in general, whether it was ram or cpu, held me back further than I would have expected. The only real advantage is power savings. In the end I put the ssd back in my desktop to live it's horrible life as my swap drive.

Great review, very pleased with it.
To address the above, all is very well and easy when you don't have to take weight and portability into account.
I own a half dozen laptops and several PCs, I am a pretty hardcore gamer, but the one that gets the most use is the little portable netbook. Its 'evolved' all by itself into the most useful piece of tech I have. Can travel with it, watch tv and order stuff online, even sit out in the sun and watch a movie.. so many uses..
Yet, so many limitations, this is where something like the 1215n comes in..
Perfect screen size - really, 11.6 or 12.1 is absolutely spot on, as 10 is too small and anything else takes away from the portability
Just enough processing power - its not a desktop machine, but not a titsy little single core atom either, it can run whatever you want, not at lightspeed, but thats not want we need, just decent speed.
HD, HD, HD - It can play movies, flash, etc that other little netbooks can't, I am not a videophile, but I cannot stand stuttering, try a .mkv on the old atom 270 - just doesn't work
ION - I won't game on the netbook, but the nerd inside me likes the fact that it can handle them, even recent titles, quite admirably.
Battery - this is key in the balance, its gotta be close to 6 hours, which really is the magic number, I know this will get 5 and a bit, so its not bad.
Price - hits the magic 500 dollar/euro mark
Those are called "criteria" - your ultraportable has to have a good combination of all of the above. A quadcore can have all the battery it wants, but if it don't fit the above then it isn't really fit the category, or the price.. or the weight.. or the portability.. etc etc

grooveboss I am going to be simple here. Netbooks running linux are great to check email and browse in bed when using a good trackball, also for video conferencing and Google voice calls and maybe some flash gaming or retro gaming. For Typing you really want an accessory keyboard, but it does not need a stance to hold its screen up when using it for word processing and the netbook can be easily hooked up to an external monitor. In my opinion since you are saving the money in the core of the system itself might as well spend the extra cash of a usual budget for buying a computer on more practical peripherals to increase productivity and still have an ultra portable machine. I think that covers for netbooks from me.In conclusion they are slow but in the future hardware will be smaller and ultra portable machines are going to be awesome.Reply
