Is something wrong with my battery?
Just got a Kindle Fire HD 7inch 16 gb.
It seems the battery runs out so fast...
I use HD battery app.
From a 100% if i turn wifi on, and close the cover (putting it to sleep), 4 hours later im at 60% - im NOT EVEN USING THE THING.
When i called Amazon, they give tips mentioned in this thread and try to prevent a return.
Whats a good test i could perform to see if something is wrong with the battery?
