Summary:The present invention discloses a method for detecting a battery voltage with a high precision, of which a RC filter network or a PI type network is applied to a handheld hardware device for eliminating the effect of a power noise on a battery voltage detector of the handheld device, while an appropriate weight algorithm is used with the software of the handheld device, such that a condition for a determination can be added to a remaining battery capacity parameter to compensate the effect of the fluctuated battery voltage caused by the consumed current, so as to detect the battery voltage with a high precision and allow users to determine the using time of the handheld accurately.
