I put it down to the SSD disk which is twice as fast on the oqo compared to others ive tested. You wouldnt want use it as a desktop at this speed but its still not bad.

“CPU is locked to 800mhz in this mode but Vista is still surprisingly usable”

Interesting that the 1.33GHz Atom in devices like the Kohjinsha and Vaio P is so often criticized for being a poor match for Vista then…

Just nitpicking but OLED screens don’t actually use a backlight. Each pixel produces its own light.

That is why a dark theme on an OLED screen should give you an extra few minutes of battery life!

Oh I ran across a “JKK edition” of the 02

A few months ago my screen turned this awful yellow/green colour. I’ve been told it’s probably the ribbon cable that needs replacing but it could be the screen.

And without any BT? BT does want a fair amount of power too, well at least in a mobile phone perspective. You’re the one with the watts and wh numbers in your head, not me

BTW on that subject am I estimating things somewhat correctly if I say the OQO 2+ want 1.5x to 2x more power than the Aigo based on your 4W comment from here http://www.solar-umpc.com/

Chippy do you see any REAL steps within the UMPC/MID market within the next year or two either within battery/solar solutions?

With BT only and with the above tweaks I estimate another 15-20 minutes but no more than that.

Along the same lines (let’s get a solution) but from another angle (less is more ).

This was news now over TWO YEARS (soon 2.5yrs) ago: http://www.engadget.com/2006/09/18/two-way-oled-displays-to-provide-solar-power/

Still nothing on the consumer market, AFAIK along these lines, not the flexibility but the fact of a screen doubling as a solar panel. Anyone know any efficiency numbers for these? Yeah I’m sure Google can find it for me

No battery charger for the Nokia? Just my point too. Why don’t these portable device folks get on the stick and come up with a standard battery design – like AA or AAA, to use in all devices. Then someone who is portable, who is in a pinch, can buy a standard battery that is something quick off the shelf to use IN ANY DEVICE if they want. Of course, they should think about the environment when they come up with this standard battery. A suggestion for a battery is as follows:

The Environmental Implications of…
http://www.bigthink.com/science-technology/the-environment/11930

quote: “The batteries can’t explode, right? I mean pick your company. They have recalls about every six months of millions of batteries that are exploding using lithium ion technology and so we explored different technology and batteries that would last much longer”.

” The typical lithium ion battery lasts some 500 charge/recharge cycles, which is if you’re running off a battery all the time, a year or a year and a half, two years. Well, ours lasts 2,000 charge/recharge cycles and so that’s like five years, right, even if you’re running off a battery all the time and lithium ferro phosphate which we use as well as nickel metal hydride, lithium ferro phosphate actually with processing decomposes into fertilizer”.

Why not? AND a universal charger would work on any battery then and we don’t have the waste of all those ORPHANED battery chargers (some that really mess up a trip because they get left at home at times) but all of them, they are useless in a short time and THEY ALL end up in landfills and the waste stream as well.

Where is the standard that is what folks want that is universal, and is also at the same time environmentally friendly?

Sounds a little hard to estimate, I guess and hope what Chippy could do is run more tests with wireless IN use and then some with it off, from there you might be able to estimate your own aprox battery time?

Care to tell us more about the yellow/green?

That screen is like $500-600 to have it repaired/replaced

If these tweaks give you a max of 3 hours of constant web browsing, then what do you estimate is the battery life with wifi or 3G off? I connect only when I need to on a mobile device and even then not for more than 15-20 minutes. My main uses for a mid or umpc are offline so I’m curious if I can squeeze out a little more battery life.

I’m surprised you need the screen at 50%. Before my screen turned yellow/green my old 02 always had the screen brightness set to one click above off and it was fine for everything except outdoors.
