Adjustment method and boot method for power-off threshold voltage and electronic device thereof

Disclosed are an adjustment method and boot method for a power-off threshold voltage and an electronic device thereof. The adjustment method for a power-off threshold voltage comprises: acquiring a current voltage of a battery of an electronic device; when the current voltage is greater than or equal to the lowest power-off threshold of the electronic device and is less than or equal to the conventional power-off threshold of the electronic device, acquiring at least one piece of application information of at least one application program, wherein the application power-off threshold of the application program corresponding to each piece of application information of the at least one piece of application information is greater than the lowest power-off threshold and is less than or equal to the current voltage; and based on the at least one piece of application information, setting the maximum application power-off threshold of at least one application power-off threshold corresponding to the at least one application program as a current power-off threshold of the electronic device corresponding to the current voltage. Turning down a power-off threshold of an electronic device through the above-mentioned technical solution solves the technical problem of the utilization rate of the battery capacity in an electronic device being low in the prior art and improves the utilization rate of the battery capacity.
