I think the Kindle is a fantastic device but does anyone find that even when it is switched off the battery seems to drain and as as result has a lower charge when I switch it back on?

don't switch it off.
let it go to sleep.

Every battery operated device loses power over time...if it's going down a lot(you don't mention how much/even approx.)then you have a problem and need to contact amazon(not post here). Do turn off the wifi and just for kicks...what do you do to power it off as you might just be putting it to sleep(there is a difference however it isn't a large one).

I just posted this information in another thread and repeat it here to avoid having to jump around to other posts:

Kindle uses Li-ion polymer batteries. For maximum battery life, leave it in airplane mode except when you need to connect to the internet. In normal use, recharge it regularly by topping off every few days and try to maintain your charge level between 30% - 80%. Never turn it off unless you aren't going to use it for an extended period of time (1 to 2 weeks or more). In normal use, try not to let the battery drain completely. If you aren't using it, you should still try to recharge it every few weeks/months.

Unlike older ni-cads, li-ion batteries don't have a memory effect and don't require charging cycles, although there's some support for the idea that completely discharging them every month or so may be of some benefit. I don't bother trying to do this and have never found it worth the trouble. With normal use, the average life of Li-ion batteries is about 3 to 5 years.

Complete information about Li-ion and other rechargeable batteries can be found at Battery University: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries

Which Kindle do you have? E-ink or tablet?

In reply to an earlier post on May 12, 2013 5:52:52 AM PDT
It doesn't matter. All Kindles, e-ink and tablets, use li-ion polymer batteries and have the same recommendations for maintainence and charging.

"It doesn't matter."

It does if the problem is due to too many books on an e-ink device and the battery drain is from the device indexing the books, or from having a corrupt book.. My one Kindle Keyboard had that problem and I was just about to toss it thinking it was a problem with the battery. As a last ditch effort I did a factory restore and haven't had any problems since.

P., just to clarify a bit.

If you are talking about something other than a Kindle Fire, it will "go to sleep" by itself, or you may put it to sleep. In this state, you will still see an image on the screen. No energy is expended to maintain that image (which is very different from a Kindle Fire, which needs to constantly expend energy to maintain an image).

While it is asleep, it can still do things. If the wireless connection (3G or wi-fi) is on, it can make those connections. It can also index books, which can be a relatively high energy use (since most things on a non-Fire Kindle don't take much energy, outside of web use including downloading from your archives/Cloud, and a couple of other things).

Turning the wireless off (putting the device in "airplane mode") will reduce that battery charge use, but not eliminate it.

When the non-Fire Kindle is actually off (you have to tell it to do that...typically by holding the power button in for a longer period than putting it to sleep), it won't, to my knowledge, perform those functions.

However, my understanding is that even when a device is completely off, the battery will still discharge (slowly). Temperature can also affect this, I believe.

So, the answer is that the battery being a bit lower when the device is turned all the way off is normal. If the device is asleep, battery drain will be faster, particularly if you leave wireless on. If the battery appears to you to be draining too quickly, one option would be to restore it to factory defaults, in case there is something you have installed that is running a process while it sleeps. That is, though, a radical solution.

If you think your Kindle is behaving abnormally, I'd contact Kindle Support. You can do that starting at

They can help you troubleshoot and suggest next steps.

CBRetriever says:
however, the sleep mode on a Kindle Fire turns off the image (black screen), so that shouldn't require battery usage to maintain

In reply to an earlier post on May 12, 2013 7:41:29 AM PDT
P. Roberts. Two things. First do you turn wi-fi off? On most the Kindles the setting for this is now airplane mode on.

Second, you may have books stuck indexing. Go to the home page on your kindle and then search for some random string of characters that isn't a word or a name. asdlprx for example. You should get no results but it's possible that you will get a report saying a book is stuck indexing. Possibly several books. If so then you need to remove those books from the device and then redownload them. Occasionally a book file is corrupted during download and that will cause it to be stuck indexing which drains power. And if you download a large amount of books at the same time the indexing function slows to a crawl so it's the same result as a corrupted file.

Bufo Calvin says:
Yes, good point. I was addressing it mostly from the non-Fire point of view. I feel like I'm going to charge my Fire every day regardless, so I personally don't pay as much attention to that. :)

I have that HD Battery app and I notice that the time for games is really small (under 3 hours of game playing, so if someone's trying to keep kids occupied on a long trip, that could be a problem

Bufo Calvin says:
That app would be used on the Fire, just to be clear for other folks.

I use text-to-speech frequently, which is also a big consumer of battery charge life. For that reason, I plug my Kindle into the car's power when driving. We have a car with a USB outlet that will do it: otherwise, you can get an adapter for the "cigarette lighter" outlet that will go to USB. That seems to keep the use pretty neutral.

Most of the newer smart phones other than the iPhone use micro-usb cables. If so, your cell phone's car charger will also work fine to charge your Kindle. I use the car charger from my Samsung and LG cell phones to charge my Kindle when I'm on the road.

I was having the same problem. "Location Services" was on, and it was draining in hours, while in sleep mode.
I switched location services off and I now have no issue. Back to hardly draining at all while in sleep mode.
I always leave my wifi on, no problems with draining. I have a kindle fire HD

I have the most recent kindle. It is non-fire and non-paperwhite. It's the cheapest, most basic version. I find that even when the device is turned off completely (by holding down the power button) after I've also turned it on airplane mode, the battery is completely drained after a month or so. In that time, I am not using it at all. It stays off the whole time, but suddenly the low battery indicator comes on. The temperature in the room remains between 55 and 63 degrees F and between 30 and 70 percent (usually in the 50s) humidity.

Jacob says:
Yes, mine does the same thing. The only thing I can think of that would use the battery when it is off would be the clock. I don't think there's any way to disable it, but I would if I could. Sometimes I am reading a real book and want to have the kindle off for a long time and it sucks when you turn it on and the battery is drained.

Don't switch it off? Why would sleep drain less than off? Mine drains completely in 2 days...from fully charged to zero, while powered off in my gym bag. Its 3 weeks old.

Update to this post- I just chatted with amazon rep who as soon as I described problem said there is a problem with battery on kindles and he is sending me new one, and return label for free shipping of old unit...

I keep reading about suggestions for using less power...apps off, wifi off, etc. But mine drains while completely powered off...goes from fully charged to nothing in 2 days. Its only 2 weeks old. Why would any of these suggestions above help if the unit is powered off as opposed to just asleep? Do I just have a defective unit? Thanks.

Same issue...did you find out why, or perhaps return the unit?

None of this has worked for me though I never tried using airplane mode...just turned off the wireless and turned off brightness...Just removed Battery HD which has started small amount of charging...I had contacted Customer service in first few weeks... but they blew me off... said I needed a new charging cable which was baloney I found out my Kindle HDX was known to have a bad Battery charging port.

Now I bought some stuff to try to solder it or replace it. Amazon service has proven to just "ignore" customers..though I would say were ordered to tell us BS

Just an FYI. If you're finding that the battery seems to be running down faster on your Paperwhite or Voyage when you leave it in sleep mode, you should check to make sure the back light is actually turning off. Turn the Kindle to sleep mode and see if the screen is still back-lit. ( It's best to do this in a darker room ). The back light should be turning off when in sleep mode but sometimes gets stuck on. This has happened twice to my wife and I. We have two Paperwhites and one Voyage. To correct the problem, you need to do a hard reboot... holding the power button down for something like 15 to 20 seconds. After it reboots the problem was fixed and hasn't happened again on either Kindle. Note that this hard reboot does not effect the books or locations stored on your Kindle.

Just FYI... Both the Paperwhite and the Voyage are frontlit e-ink ereaders. Tablet devices such as the various Fires are backlit. There is a difference.
