They are used as a signal that the Kindle is in sleep mode, so they are actually "battery savers". If the wireless is explicitly turned off, I don't know how much difference it makes. I also saw a post, which I did not necessarily believe, that the screen saver mode is identical to actually turning the device off (except that the latter gives a blank screen - again as a visual clue that it is "off").

Yes, I wonder this about my Kindle, they don't make it very clear in the docs. It has what is called "sleep mode" which you can put the device in, or it goes into itself after you don't turn a page for a while. This is when the "screen saver" pics are displayed. Or, you can turn the "power" switch off which blanks the screen.

So, is the only difference between sleep mode and off that the screen displays a pic? Of course, they screen doesn't need power to display the pic so there is no difference there. Turning the machine on and taking it out of sleep mode seem to take the same amount of time... about 5 seconds.

Thank you - that makes sense. It sounds a little like the Gen3's auto power-off feature, but that just blanks the screen (and powers off the machine) after a certain period of inactivity.

I think it's just meant to be pretty. They used beautiful greyscale bitmaps that look fabulous in greyscale and on the eInk display. Some people here have made more images that you can add, as well.

Battery savers? NOPE! Battery wasters. Every time the screen updates, some of the battery is used. So this "screen saver" is actually not needed to save the screen nor is it saving any battery life. It's just a feature that's not needed at all since it doesn't do what it is claimed it does.

I like the feature. I use it as an opportunity to upload my own pics containing contact information should my Kindle be lost or "walk away".

But it's not using any battery life either (provided it's just a static image); it takes just as much battery power to blank the screen as it does to display any other image

Its just showing the screen saver image, no updates to the display.

Doesn't the kindle search index database get updated in suspend mode (assuming you recently bought some books that have yet to be indexed)?

You're all forgetting: it disables the next/prev keys and any other keys which may lose your place in the book. The HOME button, the search button, etc..... It may be saving some battery by not scanning those buttons -- but it sure saves frustration of having lost your place in the book!
