It was working just fine when I went to bed last night, still almost half battery life.
When I woke up, it was off, and it wouldn't even turn on enough to tell me the battery was dead. When my boyfriend plugged it in, he said the charging battery icon popped up, but then it went away. I wont pop up anymore and it still wont turn on.
I've tried removing the battery while it is and isnt plugged in, Ive removed the MircoSD card, and still nothing.
What is wrong??

Try charging it for a few hours, possibly a bad battery, or just went bad.

Its been charging for 3 hours already.
It did this when I first got it, but it worked after 15 minutes.

Possible bad battery. Is it possible for you to stop by a store, most of them will give you a battery to test.

Same thing happened to my 9000. Called warranty support and they shipped me a battery. Put it and it worked.

Ill have to give it a try, but I don't really have the time to wait for a new battery, or a car to drive to the store.
No insurance or warranty on the phone because I got it off of ebay 5 months ago.

Then you will likely need to purchase a new battery on your own.

it seems to be the battery, change for a new one

If not the battery, then the USB charging port on the device is bad. Make sure that you can return the battery if a new one does not solve your problem.
