Abstract

The invention discloses a low-battery reminder method and electronic equipment, and relates to the application field of electronic terminals. When the electronic equipment is low-battery and not charged in time, the electronic equipment can still be started and used again. The specific embodiment of the present invention includes: after obtaining the remaining power of the electronic device, when it is determined that the current remaining power is less than or equal to the preset power value, performing a shutdown operation, wherein the remaining power corresponding to the preset power value can support electronic equipment. At least one restart operation of the device enables the electronic device to be restarted to provide services to users after being shut down due to low power. The technical scheme of the present invention is mainly applied in the low-battery reminding process of electronic equipment.

Description

technical field [0001] The invention relates to the application field of electronic terminals, in particular to a method for reminding low battery and electronic equipment. Background technique [0002] At present, the application of electronic equipment is becoming more and more common, and has penetrated into all aspects of daily life. Electronic devices require power to function. However, during use, the user often encounters the situation that the corresponding functions of the electronic device cannot be used due to insufficient or exhausted power, or even the situation that the electronic device cannot be turned on normally. When the battery of an electronic device is low, a warning message is displayed to remind the user to find a power source or a spare battery. However, under normal circumstances, when the electronic device is low in power, the user often does not see the warning message in time, so that the battery power will slowly run out, and when the user urg...
