Improve your UMPC performance….for free.


Loox U with desktop screen

I’m sitting here in front of a huge 1920×1080 screen with a 1280×800 screen as an extended display. Windows 7 is running and I’ve got 10 Firefox tabs open, Windows Media player, Tweetdeck, Windows Live Photo Gallery, Windows Live Mesh, Windows Paint and Windows Live Writer running. (Love those Windows Live apps!) It’s all running smoothly on the tiny Fujitsu Loox U (U820/U2010) in 1GB RAM.

The last time I was able to do this was with the 1.8Ghz version of  the OQO 2+  but it wasn’t as smooth as this. Why?

1 OS

2 Fast SSD

3 NoScript

Point 1. Windows 7 is better than Vista. No argument.  The second point is also well known. A fast SSD helps with program and file access. It also helps with swap files when, in situations like this, you’ve used up all your memory. I’ll talk more about the (awesome) Runcore Pro IV that i’ve got installed, in another post. (Hint: 80MB+ max read speed)

The last point is something I’ve talked about before but can now highlight in a very very simple way.

With 10 tabs running on Firefox, the chances are that you’re using a few heavy ajax or flash-based sites. It should be no secret that web browsing is one of the most CPU intensive tasks you can do on a device and even if you’ve got windows minimised, it’s still using the CPU in the background.

Enter Noscript.

I’ve used Noscript in the past to optimise my browsing experience and there are other, more scientific tests that highlight the advantages but today, because of the dual screen setup I have here, the effect is extremely pronounced.These two CPU graphs taken over about 2 minutes of browsing, show the difference.

Before. Browsing websites. Hitting CPU limits. You can see the typical heartbeat of a flash animation.

beforenoscript

After. Browsing websites. CPU not hitting limits. Average utilization is much much less and that heartbeat has gone. A few more processes running in this test too.

afternoscript

Side-by-side view:

 beforenoscript (2) afternoscript (2)

The difference is huge, very noticeable and within 2 minutes of installing NoScript, the fan turned off. It’s firing up every now and again but it’s not pegged on like it was before. As I type this I have 12 tabs open, the Firefox process is averaging 4.5%. I’ve done tests like this in the past and seen the CPU averaging 15-20%.

Bloggers and advertisers will hate you for it but if you’re using a UMPC, it’s one of the best CPU/Battery life/heat/noise savers there is out there. And it’s free.

Pause when minimised.

There’s something else that can be learned from this. When using web-based applications, there is no such thing as a device in standby. ARM and Intel would do well to encourage desktop browser developers to enable an optional ‘pause when minimised’ feature (there’s a reason that the iPhone doesn’t multi-task) . It will have a huge effect on the mobile web experience. If it saves as much as I’ve just seen it would be more significant for the mobile web than a couple of years of technology development. I vote for Opera 11 to have this feature. Combined with ‘Turbo’ it would make Opera the best browser for mobile computers.

Mobile Solar Computing with the Viliv X70 UMPC


I just wanted to give you solar computing fans a quick heads-up on a new solution that you should consider. The Viliv X70 EX.

I’ve been testing it for the last week and as a standalone UMPC its a really flexible solution. SSD and 3G options, high quality build and very long battery life. In tests, I’ve been getting 5-6hrs battery life and seeing great productivity levels using either the on-screen keyboard or a USB keyboard and mouse. The best thing is that the car-kit includes an adaptor plug for 12v => 9.5 but the input voltage can rise to 24v making it perfect for attaching direct to a 24w or even 12W solar panel. One issue however is the gloss finish on the screen. Viliv are producing a filter though so this should help a lot. I will get one and test it soon.

Initial plug-in test worked but I need to work-out the minimum sun power level needed and the full-sun charging time.

Stay tuned for more test results. In the meantime, check out my full review at UMPCPortal.

The Cheap, All-In-One Solar PC. iUnika Solar Announced.


Does this mean goodbye to my solar panel, my 1KG lead-acid battery and the box full of cables I have? Does these mean that you won’t have to spend over $1000 on a Solar UMPC kit now?

iunika-solar-powered-umpc-550x412

iUnika have announced a range of very low end, low-cost netbooks which include one with a solar-panel on the back. The price: $260.

  • 700gm
  • 8″, 800×480
  • 400Mhz MIPS CPU

It’s eco friendly too “..the system body’s is made from bioplastics and other biodegradable materials derived from starch and cellulose” [source]

Here’s my take. Using a PC in the sun is hard work on the eyes and hard work on the battery as you need to pump up the backlight. The solar panel is also very small (I estimate 4W max output) so with a device that’s likely to be in the 3-4W operating power range, it’s at best, a trickle charger that can keep the device topped up when not in use. Putting panels on PC’s does a nice job of cutting out the losses you get when charging external power banks but they need to be detachable to get the best use out of them.

Still, bravo to iUnika for doing this. There are definitely some customers that would benefit from this. Education in hot countries with poor infrastructure comes immediately to mind.

How will your computing habits change when we reach all day battery life?


batteriesThis thought popped into my head today for no reason what-so-ever and I wanted to see if I could get a discussion started.

Imagine this: One year ago, there was a huge battery breakthrough. All of your mobile tech gadgets have a battery that is good for an entire day of computing. I’m not talking about what a big company calls “all day computing inch (maybe 8 hours?), I mean 24 hours of continuous use on a single charge no matter what task you are doing.

Now answer these two questions:

  1. How would your current computing habits be different (other than ‘work longer’)?
  2. Two years down the road, what would gadgets evolve into, knowing that they were designed with all day battery life in mind?

When you are done, tag some people who you’d like to hear thoughts from.

Allow me to start:

How would your current computing habits be different?

First of all I think I would remove all of the wireless radio toggle software from my devices. Why turn them off if we have the power? Second, I might carry a more powerful device as my pocket computer. I would probably use the UX180 in place of my current iPhone, knowing that I could get more done on the 180. There probably wouldn’t be much need to turn my devices off so I would have an always online status. Services like Google Latitude would be active on my devices so friends could see me and I could see them.  I used to carry my UX around in my pockets, but I also needed to bring the AC adapter with me.

Two years down the road, what would gadgets evolve into knowing that they were designed with all day battery life in mind?

I think that smaller devices that would function as notifies would become popular. Envision a normal looking wrist watch, that has 3G connectivity and GPS, aggregating all of your notifications (email, IM, social networks, etcetera) and tells you what is going on right then, without having to pull something out of your pocket. I imagine a vibration from the watch letting me know that a friend is nearby (located with something like Google Latitude), and clicking a button on the side of the phone at that time would connect via Bluetooth to my phone and call my nearby friend. The watch would display other short info like micro-blog updates or SMS from my phone right on its own screen. I think that HD content would be much more prevalant, given that even handheld cameras would be powerful enough to do all day HD recording. This might have an affect on demand for faster bandwidth because people would be flocking to YouTube to be uploading or watching lots of HD videos, and they would want to do it with the same speed that they are used to watching SD videos.

More smartphone battery life red-flags.


Jon Stokes, one of my favourite mobility-focused journalists, wrote in ARS Technica about battery life on the Palm Pre a few days ago and brings up one of my favourite topics. Battery life.

It’s a real issue for smartphones now as the platforms reach levels where they can be considered capable of returning an acceptable web experience but when used in such a scenario, the battery life is too short. Losing your mobile communications because you spent 2 hours messing around on the Internet isn’t the situation most want to be in.

All day battery life on a smartphone!

Read what Jon has to say about the Pre battery life here:

The Palm Pre’s possible Achilles heel: battery life – Ars Technica.

And check out my thoughts on the Pre too. I’d rather see the Pre as a MID than a smartphone. It will still be pocketable but you’ll be able to fit a decent battery on it and still have it in a pockateble format. It’s better for many people to split voice from Internet on separate devices to improve both experiences to the ‘pro’ level.

I’ve also taken a look at this topic in these two articles:

How long does your smartphone last in ‘MID’ mode?

How big is an ‘all-day’ Mobile Internet smartphone?

Save battery life, time, the world! Use a script blocker.


Admittedly, its not difficult to imagine a scenario where less CPU cycles result in less power drain and this method isn’t going to magically extend your battery life by much but its nice to see the theory tested to the extreme.

SecTheory.com took a notebook PC, a couple of browsers and measured the battery drain on the Top 100 Alexa sites. They then took the worst offenders, that is, the ones that took the most power drain, and blocked script and ads using NoScript and AdBlock Plus. The results were quite significant. On a Dell Inspiron B130 notebook, with a 1.5GHz Celeron M processor and 1 Gig of ram, running fully patched Windows XP SP2, the power consumption when browsing the worst offending sites dropped by 11W, a 20% reduction. If its a 25W TDP CPU we’re talking about here, I can believe the results because browsing website has grown to be a very CPU intensive task.

The effect would be much less on netbooks and UMPCs but I would expect the same test to save 1W average which is about 10% – about 15 minutes for a device with a standard battery. Of course, its not really normal to be picking the worst offending sites and continuously hitting them either. Under normal browsing use, you probably wouldn’t notice any difference but there’s something else you need to be aware of.

Script not only takes CPU and battery life, it takes time. Time to execute, render and in some cases, time to fetch the remote code. By disabling script you significantly improve browsing speeds on low power devices and by definition, you save battery life. I tried it a few weeks ago with the noscript plugin and I’ve seen many comments on UMPCPortal from users that also use the technique. It really works! You lock yourself out of application sites like Google reader initially but it doesn’t take any effort to enable exceptions for these sites as you go along. No more hung page loads waiting for remote sites to time out. No more of those terribly annoying auto-start video ads that make browsing on a low-end PC a misery. There’s even an improvement in security. Its a win-win-win!

Try it. Install the noscript plugin and see how you get on. Yes, I risk killing all of my advertising income if everyone does this on all their devices and I’m sure there are bloggers out there that will read this and cringe but I trust you’ll only use it on your netbooks and umpcs and put the exception in for your favorite sites! Long live the choice between simple html and web2.0!

Solar UMPC Camping.


I’m going camping over the next four days. Here’s the kit that’s going to keep me productive.

[The Wife and little-one have planned a last-minute camping trip together and I was due to stay home and work but I’ve decided to go along and make a working holiday of it. Dads – this is the beauty of Ultra Mobile PC’s!!!]

IMG_6871 

That’s a Samsung Q1 Ultra being charged from a Tablet Kiosk MP3400 which will be charged using a Sunlinq 25W solar panel. Also included are the Nokia N82 and a battery charging set. More details here.

Check out Solar-UMPC for some more mobile and solar-computing posts over the next few days.

85% of people want 4 hours or more battery life.


A clear message to ultra mobile PC OEM’s

{democracy:4}

If it wasn’t clear before, it is now. [If the results are not showing, make your vote and you’ll see them.]

While some people will accept 3-hours battery life for an Ultra Mobile PC, 85% of people want 4 or more hours. 50% of people here see 5 hours as minimum battery life for a UMPC.
