I use the app Android Booster. Set to optimize automatically and when you want to shut it down for the night, hit optimize three times (I want to make sure I get everything) and hit okay those three times. Shut it down and the battery does not drain...at least on mine. But...make sure you have it at a high enough level upon shut down so you are set for the next session. I usually charge it to 90% or so when I shut it down and it stays close to 90% when I start it up.

I have exactly the same problem on my Kindle Fire, it bothers me a lot. Have you fix it?

I have the same issue. The device is useless if I have to always be charging it when not in use.

WOW. Amazon agreed to replace it as soon as i told the online chat agent about the problem. Took only a few minutes. VERY good customer service.

I turn off my wifi when not using it. I saves on my battery and my kindle charges over night. I don't have the KF HD but maybe that will help.

Thanks Bill, will do that next, then go to Amazon Support.

Thanks!

Yea, that isn't normal. It sounds like a defective hardware (battery or Kindle) to me. I would contact Amazon.

Not pretending to be a Pro here but - If you have sideloaded apps, you might consider following jsh1120's advice to install Android Assistant. Running that app might tell you which apps are consuming battery power while the device is turned off. This assumes that you've already done a hard reset, calibrated your battery, etc.

Hi jsh1120 - thanks for the tips. i calibrated my battery then completely turned off the device for overnight. From 11pm to 7am, completely shut down, my Kindle Fire HD 7" battery drained from 100% charged to 71%, a drop of 29%, while completely turned off. Should i contact Amazon support? Doesnt seem normal to me.

Folks, a couple of points.

() If you have truly shut down the KF (not just put it to sleep) and you are seeing a significant battery drain after turning it back on, it's likely that the battery monitor software is "out of whack." To deal with this problem, download "Battery HD" from the Amazon Appstore and "calibrate" the battery. Look in the tools in the app. If that doesn't solve the problem, you have faulty hardware and should contact Kindle CS.

() If you're seeing what appears to be abnormal battery drain while the KF is turned on but not being used there are a couple of things you can try.

1. Follow the usual tips to turn off wifi, adjust screen brightness (if the screen is lit), etc.

1A. Reboot your KF to clear the system memory. (i.e. press and hold the power button for 30 seconds etc. )

2. Download an app like Android Assistant. It runs in the background and will provide a list of the apps and other processes that are draining your battery. For example, after letting the app run for a day or so, you may use, say, 80% of your battery. Android Assistant will tell you (hypothetically) that 50% of your battery use was for an email app. That means that .8*.5 = 40% of your total battery has been consumed with notifications from that app.

If you see a process you don't recognize or seems to be drawing an inordinate amount of power, investigate further. If you can find the app, try deleting its cache and data. Corrupted data sometimes prevents an app from properly shutting down.

For example, several days ago a user found that an app called "Docs" was gobbling up her battery. Once she installed Android Assistant, it killed a rogue app that was otherwise impossible to stop, even with a reboot. The problem disappeared.

3. Finally, if all else fails, try resetting to factory settings and re-registering the device. If you haven't done this before it may seem very scary. It is a bit of a PITA but unless you have loaded your KF with lots of side loaded apps (which may be the source of the problem) reconfiguring the device will probably take only about 15 minutes or so. Probably less.

Does the battery drain much when in sleep mode? I have a Marware Revolve case that puts the Kindle 8.9 to sleep when I close the cover. I haven't run any tests yet but I can certainly shut off wi-fi before putting in sleep mode since that will help conserve battery strength.

Not *that* much.

I would suggest people with batteries draining even when the device is off to first charge the device fully and then perform a hard-reboot (unplug, keep the power button pressed for 30 seconds ignoring any messages, release, press briefly again). If this helped, the software controlling the charging process was confused.

If the problem persists, it would be best to contact CS ("Help" at the top, then "Contact Us", or https://www.amazon.com/gp/help/contact-us/kindle-help.html - you can have them call you).

possibly it requires a lot of battery to restart?

I fully charged my Kindle Fire HD overnight. I turned it on briefly at about 1 p.m. & put it to sleep at 99%. When I turned it on about 8 hours later, it was still at 99%, according to Battery HD.

I have this problem on 1st gen Fire. Shutdown and drains to 0% after a day off.

In reply to an earlier post on Oct 17, 2012 8:58:12 AM PDT
Thanks for the reply.
But I actually turned off (shut down) the kindle fire HD.
Last night it was the same, I shut it down with 29% battery level and this morning when I turned it on it was on 9%. (It drained 20% in 15 hours being shut down).
Am I the only one with this problem or is a general problem for this tablet?

Rodrigo,

Your kindle is not actually turned "off" when you press the power button, it just goes to sleep. In sleep mode, the KFHD will still access your wireless network, and apps you have running may still work in the background.

You can turn your Kindle Fire HD completely off by holding the button for about 2 seconds. It will then give you the option to "shut down". When the tablet is shut down, your battery will not drain perceptively. (Li-ion batteries drain very slowly even when the device isn't on, but it shouldn't be noticable overnight.)

If you don't want to shut down your KFHD all the time, you can disable the wireless before you put it to sleep. That will help significantly with battery life.

The battery went from 78% to 59% while the tablet was turned off last night, is this normal?
