HELP!!! My kata i3 phone won't turn on or charge, what should I do???

[AC Question]

I got home late and my kata i3 phone had a 0% battery and i charged it, 15 minutes later i saw that the battery is 2%.... And i was really tired that night so i went to bed and sleep, 4 hours later i woke up and tried to turn on my kata i3 phone but it doesn't turn on, i tried charging it for hours but it didn't work, i also tried using the volume down+ power button trick but it doesn't work too.... The battery is non-removable battery so what do i do?? Sorry for my bad english....

Welcome to Android Central! Try a different charging cable and plug, and let it charge on a wall outlet overnight (i.e., for at least 10-12 hours). Then try pressing and holding Power for at least 15 seconds. If nothing happens, the battery might have failed -- you'd have to bring it to a repair shop to replace, or see if there's a do-it-yourself video on YouTube for that phone (I couldn't find one with a quick search).
