1. Did your phone get wet? If do you may have a short.

2. Do you have constant applications running? Processor use will warm your phone (and drain your battery). Go Settings > Battery Try to diagnose if some applications are constant.

3. Is your battery bad? Spin your battery while flat , if it spins easily (looking for a bubble) it is bad.
