Assuming there are no other differences that would effect the weight.

Euro version is 336 grams - mind you I put an 8gig card in so it's carrying a LOT of books

That is if we can get the DR800S and DR800SG together in one place using the same very precise scale.

Both have the same weight in the specs listed on their website, whatever that means.

Has anyone asked iRex? That might be the easiest way.

Same as you. The expensive European one, without 3G.

Could we expect Irex to tell its Euro DR800 users that yes 3G chip is in your reader but we disabled it? I am not so sure they would.

I don't see why not. They've been pretty honest in the past about the fact that they couldn't work out any agreements with carriers. Telling us whether or not the chip is physically there wouldn't be saying anything they haven't already admitted.

I suppose one can ask, "When you work out the wireless deals with the carriers, can I 3G enable my dr800s with a software update or do I need to buy a new device?" Then again, if other countries have something like the FCC, I wonder if you can certify a device for wireless use *after* it's sold.

The dr800s manual doesn't mention a SIM slot like the US version but does the physical device have one?

It's just head-shakingly unbelievable what some of you guys will put up with from this company and yet still attempt to defend it in some way or other. Someone is getting a 20% battery drain from an e-ink device that hasn't been used for 3 days and this is somehow a good thing or at least acceptable to you? My Sony will sit unused for a week without needing to go into some kind of blank screen standby mode and will still show a full charge when I pick it back up. When I go to read with it after all that time, the response is instantaneous; it clearly hasn't dropped into some kind of hibernation mode.

Wow, a battery drain problem in an IRex device. What a shock...

Hmm, I had a 500 and a 505 and they would both drop after a week of non-use. The Sony's had great battery life, but they did drop in charge on me when just sitting in standby mode.

Yes, mine will, too, but it will sit there for a week without any charge loss showing. After I start reading with it after that length of time, it will retain the full charge for several pages, and then it will show a one bar loss. Since the meter shows 4 bars, I'd estimate that I've lost about 23% after a week of non-use, which close to double a 20% loss in 3 days.

Now, that being said, I'd be interested to know the size battery Sony uses versus the size of the DR800's. If the Sony uses a smaller battery, that makes things out to be even worse for the DR800 - it basically says they've never been able to figure out effective power management and just tried to solve the problem with this unit by tossing a larger battery in it.

Your Sony does go into a standby mode when not in use, whether or not it blanks the screen doesn't make a difference. You're implying that the Sony will last forever in that mode? That's not what most information I've seen says. Which Sony do you have? Most of what I've seen says the Sony's get a couple weeks on Standby mode. The wiki says "less than a month" for the PRS-505. Doesn't specify for the other models, but threads in the Sony forum seem to indicate it's similar for the others.

The DR800 will wake up out of it's standby mode nearly instantaneously as well.

That's because it's gone into standby/sleep mode (whatever you want to call it) and isn't refreshing the screen. The meter doesn't change if the screen isn't refreshed, so it's not showing you an accurate reading.

TGS · 03-12-2010, 04:48 PM

It's just a guess but presumably simply powering an 8.1" screen takes more juice than a 6" screen. But the point is not really about absolute lengths of time batteries will last between charges (not least because as Shaggy and (I think) mgmueller have advised me elsewhere, keeping the battery topped up is better for the battery than letting it fully discharge). More importantly for me is whether the power management facilitates my use or gets in the way of using the unit and becomes a pain. For me something like a week with two or three hours a day reading, a bit of side loading, some flipping about between publications, and a bit of word searching between charges would be perfectly fine. I'd probably want to plug it in over the weekend to top it up whether the battery meter said 60% or 5%. However, four days between full and empty and doing nothing would be a pain.
