Why won't my phone turn on?
Phone was dropped then it turned off with a full battery. When pluged in or trying to turn it on only the dead battery sign and Apple sign flash on the screen. Then it goes back to nothing.
苹果 iPhone 5s 于2013年9月10日公布。该设备的维修与以前的型号相似，需要螺丝刀和撬棒。可使用GSM或CDMA / 16、32或64 GB。颜色有银色、金色和太空灰。
Try restoring the phone but you are going to lose all your data.
If restore doesn't help you may need to replace parts but it is hard to say what may have gone wrong with the phone and you will need to find if some part is broken or you have damaged the logic board.
First try restoring and then we can look for another solutions.
