I dropped my phone and now the power button doesnt work. But now my phone ran out of battery and there is no way i can turn it back on because the power button stopped working.

@roberto21 you will have to open it up and take a look at what actually got damaged. Use these guides and teardown Samsung Galaxy Note 5 Repair to actually get into the phone. Your battery should charge regardless of your broken power button.

Take off the back of your phone and where the power buttons at remove the plastic button and actually see what is is pressing and use your finger to turn on
