Donna | 50 comments Forgive me if this has been discussed before, but this is a question I have wondered about since I started using my kindle. I have not seen an answer.

If you are reading your kindle and you are going to stop for a few minutes (let's say 5 to 10), are you better off a) just leaving it on to go into hibernation or "sleep" mode, or b) shutting down completely?

Now I realize there is a time element involved, short distraction vs long phone call, ect., but there is nothing that gives me definite guidelines.

Does anyone know when it is more efficient to power down vs. "sleep"?

Always put it on sleep. Amazon has always advised this. The Kindle is designed that (when the wireless is turned off) the Kindle only uses battery power when changing a page. It can stay on standby for years without using any power (supposedly). But it uses a fair amount of power when powering off and on.


message 3: by Charles (new)

Charles (NogDog) | 13 comments I would say just sleep, remembering to turn off the wireless first if you have no reason to leave it on. An exception might be if you know you won't be using it for quite a few days, in which case I'd probably turn it off.


message 4: by Donna (new)

Donna | 50 comments Thanks, guys. I've been powering it off whenever I'm not going to use it for more than 1/2 hour or so. (I always have the wireless off unless i'm downloading a book.) It sounds like I've been doing it all wrong!

So your advice is to leave it in sleep mode even overnight, right?


message 5: by Charles (new)

Charles (NogDog) | 13 comments Yeah, you should be fine that way. I just put mine on sleep when not using it, and usually only connect it to the charger about twice a week (and usually never get below about 50% charge).


message 6: by Robert (new)

Robert | 58 comments Sleep. ZZZZZzzzzzzzz.....


message 7: by Jennifer (new)

Jennifer Gentry (AuthorJenniferGentry) | 18 comments Some advice I receive from the Amazon Kindle community was NEVER (as much as possible, anyway) let it get below 50% charge and to only shut it completely down about once a week or so (unless you know you're not going to use it for several days). Shutting it completely down is actually harder on it and uses more battery than just putting it in sleep mode apparently.

When I'm done reading for the night or for an extended period, I put mine to sleep. Just tonight I shut it completely down, but it had been at least a week since I'd done it last.


message 8: by Elena (new)

Elena | 46 comments Thanks for asking the question, you were not the only one doing it all wrong. I was always letting the battery run out before charging, and always turning it off.


message 9: by Sally (new)

Sally Pearce | 20 comments Amazon told me when I first bought my K1 (over 2 years ago), to just put it to sleep and put it on charger at night. I've never seen my charge go down. Ever. At all. I've never turned mine off.

I'm glad I'm not the only one, Elena. I was doing the exact same thing! I was even powering it off if I wasn't going to read for a couple of hours.

Sally (and others) = thanks so much for all the helpful tips. Sally, did you contact Amazon yourself? I never talked to anyone. I guess I should have!


message 11: by Donna (new)

Donna | 50 comments BTW, I still can't understand how sleep mode, which has a picture on the screen at all times, uses less battery juice than a blank screen. Just saying....


message 12: by Sally (new)

Sally Pearce | 20 comments Donna,

Yes, I called Amazon Kindle Support. They are really helpful. Look for help or contact us; then they will call you immediately (if you're by the phone). That will be Amazon customer service. if you need help with the Kindle, tell them that and ask for Kindle support. Easy as pie.

The Kindle only draws power when it changes the page, not to keep the image on the page.

Think of epaper as having a bunch of dots inside it that are black on one side and white on the other. When a page gets loaded, the blacks and whites get switched into the configuration that you need to make the image or words. It stays there until current passes through the page again to change the image.

It's like the Etch-a-Sketch before you shake it.

Great analogy!


message 15: by Britt☮ (new)

Britt☮ (genki_bee) | 55 comments I only turn mine all the way off on flights during takeoff and landing... otherwise, sleep mode.


message 16: by Bryan (new)

Bryan Craig So, if you charge the battery at 50% or hook it up every night, does the battery hold a charge? I thought batteries lose its "juice" if you keep charging it without letting it go way down.


message 17: by Madelyn (new)

Madelyn  (madelynteresa) I'm not even sure how to turn mine off all the way. I've had it for about six months and only have used the sleep mode. How do you turn it completely off?


message 18: by Sandy (new)

Sandy | 29 comments If you want to turn it off you have to slide the power switch and hold it for about 4 seconds

Okay, so all the way off is when no screen saver shows right? I have only done that by accident a coupla times. Otherwise its sleep mode,right?

That is my understanding also and that is why I was letting it run down. Maybe this battery is different?


message 21: by Kip (new)

Kip Williams (kipwilliams) | 6 comments Lithium Polymer batteries like those used in the Kindle 2 and DX, do not develop a 'memory' that was common with earlier NiCad batteries. The older batteries would lose their ability to accept a full charge if they were left on a charger or recharged before being drained. Not having that problem is one of the big advantages of the Lithium Polymer cells.

Yep. If it's on sleep mode, there will be a screensaver. If the screen is blank, you've turned it off.

I keep reading different thoughts on this. I thought someone said they talked to Amazon customer service and were told to recharge only after the battery was depleated (when it says "You should recharge now") and NOT to plug it in "early". I'm so confused...


message 24: by Heather (new)

Heather (LovingMyHusbandAndMyBooks) | 5 comments I thought I would put this out here... I didn't even know how to turn it all the way off until we had to fly to Germany and after fumbling with the sleep button for a bit I finally got it to go off >.< lol


message 25: by Jeff (new)

Jeff | 33 comments Do you have to turn the Kindle off or is it ok to just turn off 3G while the plane is taking off/landing?


message 26: by Amanda (new)

Amanda (Shandril19) | 8 comments By FAA rules, ALL personal electronic devices must be off when the plane is taking off/landing, even those that have no cell/connectivity in the first place.

(Which is not to say that I always do it, but it is the rules.)


message 27: by Terri (new)

Terri (clanmoran) | 76 comments I actually had a flight attendant stop and tell me to turn it off and I said the same thing you did Jeff, but she told me it did not matter "if it has an on/off switch it MUST be turned off"


message 28: by Jeff (new)

Jeff | 33 comments Interesting. Thanks for the info. We're flying in 2 weeks and I was planning on taking my Kindle on the plane with me.


message 29: by Jackie (new)

Jackie Lane (jaxlane) | 17 comments @ Jeff, don't pack it far down because they make you take it out and put it on the conveyor in it's own bin, just like they do with laptops.

Jeff | 33 comments Jackie wrote: "@ Jeff, don't pack it far down because they make you take it out and put it on the conveyor in it's own bin, just like they do with laptops."

Also very good to know. Maybe I'll just take a DTB with me. :)


message 31: by Terri (new)

Terri (clanmoran) | 76 comments I just recently flew, and I was not made to take it out like my laptop....its not that much of a hassle, I still would that my Kindle before DTBs!! :-)


Shannen *aka Mrs. Jericho Barrons* (ShannyBananny71) | 55 comments I didn't have to take mine out either. Just left it in my purse.


message 33: by Jackie (new)

Jackie Lane (jaxlane) | 17 comments I would still take my Kindle, it's not a big deal, but they wanted to put it though like a laptop every time I have flown.


message 34: by Jackie (new)

Jackie Lane (jaxlane) | 17 comments @ Jeff, if you are going to the beach/pool, I would bring a gallon plastic bag so you don't get water/sand on it.


message 35: by Elena (new)

Elena | 46 comments Jackie wrote: "@ Jeff, if you are going to the beach/pool, I would bring a gallon plastic bag so you don't get water/sand on it."

Amazon sells a water proof cover, it is not as cheap as the plastic bags, but I use it enough to justifify it :)

I always leave my Kindle on and read while taking off. The flight attendats have not told me to turn it off, I guess they have not seen me. You can put your cell phones on "plane mode" while traveling, which is bascially the same has having your Kidle with the wirelless turn off, so I don't know what the problem is.


message 36: by Sandy (last edited Jul 27, 2010 11:41AM) (new)

Sandy | 12 comments I've never had to take my Kindle out of my pocketbook going through security, and I've flown a few times since I got it. On the other hand, the flight attendants have very specifically announced that "everything with an on/off switch" has to be off during takeoff/landing, and sometimes specifically mention Kindles (as well as IPods).

No big deal - I still prefer to have it for the flight time and the sitting in the airport time. On our last trip, we wound up with a 7 hour delay in Chicago in the middle of the night - I was VERY glad to have my kindle, because I would probably have not had enough reading material to keep me going, and there was nowhere open to buy anything.


message 37: by Sandy (new)

Sandy | 12 comments I emailed Customer support today, to ask about the sleep versus turn off, and also about the battery recharging. The email response was worthless (told me how to put it in sleep mode and how to charge my battery), but when I clicked on the button saying that the response was not helpful, they gave me the option of having someone call me right away.

I can't vouch for the accuracy of any of this, but this is what the Kindle support person told me:
1. It's not a good idea to be turning it on and off several times a day, but beyond that it doesn't matter. She suggested that I turn it off if I'm not going to be using it for 2 or 3 days.
2. The only issue with recharging the battery, she said, was that rechargeable batteries only have so many recharges in them. So, the more often you re-charge, the sooner you use them up.


message 38: by Donna (new)

Donna | 50 comments Sandy, the info about the battery was very helpful... I guess that means I'll wait until it is low enough to tell me to recharge. (I was worried about letting it get too low and running out of juice at the worst possible time!) I'm not real happy after the amount of money it costs to hear it has a definite "shelf life"... Did they happen to mention how many times?

It should last as long (or longer) than a (modern) cell phone battery since most people use their cell phones more/as much as their Kindle. I think the battery can be replaced by Amazon if you want to send it in and pay for it, but don't quote me on that.


message 40: by Donna (new)

Donna | 50 comments Well, depending on how much that costs, it might make more sense to upgrade to a DX... Hmmmmmmmm, excuse me while I charge my kindle! ;)

I asked about replacing the battery, since the subject came up. She told me that if it died after a normal life span, it was replaceable, but there is a charge for it. I figured no point getting into what the charge would be at this point, since things change. She also said that it last a "really long time," but that's not really telling me anything!


message 42: by Lauren (new)

Lauren | 7 comments I didn't know that there was a way to actually turn it off. I thought there was only sleep mode. So i've learned something new today.


message 43: by Kathy (new)

Kathy (bookgoddess1969) Thanks everyone. I've been wondering why I keep having to charge my Kindle and I was afraid I would have to have it looked out. I always have the wireless on and I turn it off even when I want to just stop for a minute or two. Now I know I was doing it all wrong. Wow! I amgoing to shut the wireless off right now. So, I only turn it on when I want to download a book? And do I ever shut off the Kindle?


message 44: by stormhawk (new)

stormhawk | 539 comments You don't have to shut it off. It doesn't draw power unless the wireless is on or you are turning a page.

There have been reports that some versions of the software encourage what is referred to as a "battery leak," though. You can probably find more about that by doing a search.


message 45: by Erika (new)

Erika | 23 comments Oh wow...I didn't know any of this. I was always turning it off. I think I'm going to have to change by behavoir. Thanks everyone.


message 46: by Tish (last edited Jan 26, 2011 02:09PM) (new)

Tish (paradiseisalibrary) | 30 comments Always put it to sleep. There is no way to turn it off. If you hold the button until it goes blank you're just resetting the software and if you do that too often you could harm the Kindle. Trust me guy's I work for Amazon as a Kindle Specialist. Do not try and turn the Kindle all the way off. If you continue to turn it all the way off you'll damage your Kindle.


message 47: by Irene (new)

Irene | 57 comments Being new here and still patiently waiting for my freshly ordered kindle to arrive, I am greatful for this info. Thanks!


message 48: by Kathy (new)

Kathy (bookgoddess1969) Thanks everyone. I've been doing everything wrong, obviously, since I got my Kindle almost a year ago. No wonder the charge never lasted long. lol


message 49: by Weenie (new)

Weenie | 55 comments Having turned mine off last night, I now know what (not) to do! Thanks for the advice!


message 50: by Linda (new)

Linda Acaster (goodreadscomLindaAcaster) | 49 comments Thanks for the advice. As a new Kindle owner who has only "lightly" read the manual (doh!) it was news that I could turn off the Kindle to a blank screen. I'll bear it in mind when I go through an airport. Alas not until later in the year.
