The disclosure discloses an impact-resisting method and device for a mobile terminal. The method includes that: it is detected whether a mobile terminal is in a damaging falling state; when the mobile terminal is in the damaging falling state, an included angle α between a vertical line based on a preset point on a preset end surface of the mobile terminal and the preset end surface is detected, or an included angle α between the vertical line based on the preset point on the mobile terminal and a plane where the preset end surface is located is detected; according to the detected included angle α and a preset impact-resisting included angle β, it is analyzed whether posture adjustment needs to be performed on the mobile terminal; and when the posture adjustment needs to be performed on the mobile terminal, according to a difference between the detected included angle α and the preset impact-resisting included angle β, a kinetic energy component is controlled to adjust a falling posture of the mobile terminal. By adopting embodiments of the disclosure, the impact to a vulnerable portion can be avoided by adjusting the falling posture of the mobile terminal, thereby improving the impact-resisting performance of the mobile terminal.
