Abstract
A method and apparatus for measuring the remaining power level of a device. The state of flag bits are detected, a password is calculated when a first flag bit is set, the password is displayed to reset the first flag bit, and the detection of the state of the flag bits is returned to; the total power consumption is calculated when a second flag bit is set, the remaining power level is updated on the basis of the total power consumption and of a second preset value, the second flag bit is reset, and the detection of the state of the flag bits is returned to. The present invention implements increased precision in measuring the remaining power level without additional component, accurately reflects the actual value of the remaining power level of a battery, and incurs no additional power consumption. This does not affect the service life of the device and is inexpensive.
