Abstract

The invention provides a power-down protection method and apparatus and a mobile terminal. The power-down protection method and apparatus are used for solving the problem that a handheld device loses power due to instant disconnection of a battery and a circuit board possibly caused when the handheld device encounters relatively strong impact or shake. The power-down protection method comprises: obtaining motion state data of the mobile terminal detected by an acceleration sensor of the mobile terminal; when the volume of the motion state data is greater than a first preset value, closing at least one application, which is being run currently, of the mobile terminal, and performing data backup on data of the at least one application; and after detecting that a power supply is disconnected from the circuit board, supplying power to the circuit board through an energy storage capacitor connected in parallel with the power supply. According to the power-down protection method and apparatus, when the battery is disconnected from the circuit board, the energy storage capacitor supplies an extra power supply to the mobile terminal; and meanwhile, a load current in the mobile terminal is reduced, and the data in the mobile terminal are subjected to data backup, so that the power-down protection is enhanced.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to an anti-power-down protection method, device and mobile terminal. Background technique [0002] Based on factors such as ease of use, most handheld devices currently use a contact-type battery connection scheme, that is, the battery and the circuit board are connected through physical contact forms such as shrapnel / hooks, rather than fixed connection forms such as direct welding. Under this design scheme, when the handheld device in use suddenly encounters a strong vibration or impact, it may cause poor physical contact (instant disconnection) between the battery and the circuit board, thus causing the handheld device to drop. Power off, bring unexpected loss to the user. Contents of the invention [0003] The purpose of the present invention is to provide a power-off protection method, device and mobile terminal to solve the problem that when the mobile terminal encounters...
