Accessories Kindle Smart Cover

Ganfas · 02-07-2013, 10:31 AM

I received my smart cover from amazon yesterday. It was a surprise to see the auto turn on-off feature.

My doubt is if this feature could possibly "damage" my kindle in time. For example, i open the cover to read 5 minutes the kindle turn on. I close the cover to go from from place A to B, 5 minutes later open the cover again. So the kindle is "always" turning on-off with few time interval.

Maybe is a dumb question but i'm a little bit apprehensive about it.

Thanks

I am assuming that you are opening the cover because you are going to read. So lets redo your sentence without the cover. " i turn on the kindle to read 5 minutes. I turn off the kindle to go from from place A to B, 5 minutes later turn on the kindle again." In other words if you need to turn the kindle on and off to read frequently it doesn't really matter if you do it by pressing a button or opening a cover. I don't believe that turning on the device frequently will have any adverse affect on it but it doesn't matter since the alternative is for you to forego reading when you want to.

I agree. I read this way all the time. 5 minutes here, 5 minutes there and I haven't noticed any difference in my battery life. Works just as well now as it did when I bought it.

Wouldn't worry about it.

I know with certain kinds of lights there are concerns about frequent cycling, HID springs to mind, but I am not aware of any such concerns with the LED's the Kindle uses.

I'd guess that there's a reed switch in the frame that detects the magnet in the cover. Can those type of switches become permanently magnetized? You'd think that the people who designed the system would have thought of such a possibility, but ya never know.

The Kindle doesn't actually turn off ever. The only way to turn it off is by removing the battery. The one thing that might be effected would be the led lights turning on and off. Don't see the problem there either - they turn on and off all the time anyway when they are "on" - and unlike fluorescent bulbs, they do not use any more energy while turning on.

I wouldn't be worried about the number or frequency of sleep/wake cycles done either through the magnet or the button but I'm more concerned about the potential effect of the magnet on the other stuff I've got in my handbag TBH. I've got an Oberon on its way to me so it's a "dumb" cover anyway, and although I can easily add a magnet I'm somehow not quite convinced that it such a great idea.

Kindle has a smart cover? Is this for the new paperwhite?

It's a Hall effect switch: no moving parts. You're safe from such failure modes.

wow... Next you're gonna tell me there are no little, teeny-tiny vacuum tubes in there. I was wondering how they kept it so cool.

*raises hand* I have a magnet that is just 1/4" x 1/4" and 1/32" thick in the bottom left area of the Oberon's interior pocket. The pocket is tight enough to hold it in place, but at the same time the magnet is thin enough that you can't tell it's there.

I have had no problems with the magnet interacting with other electronics, credit cards in my purse, etc. Between the small size of the magnet and the thickness of the cover leather, I've found that its effective zone is perfectly limited.

Oh excellent

It's probably going to be a while until my Oberon arrives anyway (the joy of international shipping!) but I might just stick a magnet in there when I get it then.
