Hi I Have The Same Problem, Too... What You Can Do is Take the case and the case that came with your phone too, and you will see a white battery, now take that battery and leave it next to a fan for 15 minutes. Make Sure the fan has no dust in it and has maximum power. After 15 Minutes, Take The Battery and give it a little shake here and there. Put The Battery Back in, and turn your phone back on. Thanks! ;P
