Abstract
Measuring the voltage level of a mobile telephone battery during a charging operation involves disabling the charge temporarily so that the battery rapidly enters discharge mode. The discharge mode voltage is more representative of the true battery charge level, so that the present invention can be implemented to provide a battery charge level display that is accurate even when the telephone is being charged.
