Kindle Fire tablet 8 Battery draining while plugged in

I have a new Kindle fire tablet 8 with Action tiles and Fully Kiosk browser running.

I have it mounted on a kitchen cabinet and the cable is running to a power strip in the cupboard. 

The battery drains throughout the day and gives me a battery warning.

Any ideas? Is it the cable? I'm using one that was suggested  with a right angle connection to fit in the frame.


Please test using the original power supply and cable provided by Amazon. That way you can determine if there is insufficient supply or a cable problem...

After that, be sure to try a lower brightness level and other minor touches might be enough to keep the charge positive.

I run my Fire HD8 with a "cheap" power supply (I don't know the specs, but it sure doesn't look fancy), and the battery seldom drains. I use Fully with complete dim mode as the screen saver.


Thanks Terry- I'll try the original connection to start

I just got my fire and have a similar problem.  Can u share what settings you used to keep positive charge?  Overnight I went from 76 to 64 with 90 angle cable plugged in but lightening bolt showing charging

For what it's worth... Mine did this for 2-3 weeks and yet for the past several days has been fine (solid 100%).

Possibly shutting it down for a white will recondition the battery? Or remove Tile Animations or such things that may be taking extra power? I can't come to any conclusions.

Oh....I think there was a FireOS system update too. Should be automatic.

Can you test with the original fire micro usb cable?  My Fire8 was fine for over a year then 6? months ago started to drain.  I had to replace my cobbled together cable/flush micro usb.  Quick test with usb meter, Fire8 battery is 100%: 

--On fire home screen 0.2-0.3 Amp

--WallPanel app with ActionTiles settings screen 0.3-0.4 Amp

--With my default ActionTiles panel (40+ tiles, animated icons, animated weather gif, etc) 0.6-0.9 Amp

FYI: The 90 degree cable with stock charging 'block' seemed to fix issue. Just not sure how to wall mount with 1.5 inch of charging block + .75 inch of usb sticking out vertically?
