This application relates to the field of battery management technology, and more particularly to a method for determining the state of charge (SOC) of a battery, a fuel gauge, a battery system, and an electronic device. The method for determining the SOC includes: after the battery enters the final discharge state, continuously predicting the smoothed remaining capacity value at the next moment based on the current smoothed remaining capacity value. Since the prediction period is generally short, the temperature and load of the battery during discharge change very little; therefore, the influence of the battery's temperature and load on its internal resistance can be ignored. Furthermore, calculating the smoothed remaining capacity value of the battery in two consecutive calculations cancels out the influence of the battery's internal resistance on the calculated smoothed remaining capacity value, ensuring a one-to-one correspondence between the calculated smoothed remaining capacity value and the battery's load voltage. This guarantees the accuracy of the monitored SOC and avoids the situation where the battery's SOC jumps directly to zero at the end of the discharge process.
