Kindle Fire HD is flat? Very odd!
Yesterday I put two Kindles away both were nearly full, but the one in question was at 86% as I had just played a movie to see what the drain was from full. The movie was played using the ES File explorer.
I put them away knowing I'd be working on them tonight. However, one started straight away, the other had a Graphic on the front showing a battery with one red bar. Taking this to mean "I'm flat!" I plug it in to charge. After 10 minutes or so I had a 5% charge on it. Has this ever been seen before? Does anyone know what could have caused it? I was under the impression that after a while Kindles put themself to sleep if nobody was using it. |

If you leave an app open, it might have a permission to keep the Kindle awake. I've had that happen before.

Hells Teeth! That's possibly what I have done!
Is there a way to check and close (if open) apps? I'm just hitting BACK to leave an app. |

Yeah apps can suck the life right out of a tablet. I use GSAM battery monitor to keep track and check for running apps. I don't keep many apps on my KF. On my SGP5 I have tons. I can say Slacker Radio is the biggest battery hog I've come across. Even after I close the app it continues to suck juice. So now I force close after I am finish and that does the trick.

I use Advanced Task Manager free version to periodically close out apps, especially if I am putting the thing to sleep. That way I avoid nasty surprises.

GSam Battery Monitor
Quote:
http://www.amazon.com/GSam-Battery-M...attery+monitor and, http://www.amazon.com/GSam-Battery-M...attery+monitor You can enlarge the battery percent left icon which will show exactly how much juice you have left at any time. They also have a table which shows exactly how much juice is being used by each app and you can go right to the app managment screen for each app from there. That will enable you to manage your power use exactly. Right now my GSam tables show following power uses: Screen = 40% WiFi = 17% Held Awake = 15% Bluetooth = 0% All Apps = 28% Of those Apps the big juice users are: Media = 7% System (sdcard) = 5% Kernel = 4% All my other apps = 12%, all of which use less than 2% each with the Appstore and Office Suite using near 2% and all the rest using 1% or less.
