Abstract: Exemplary embodiments are directed to systems, devices, methods, and computer-readable media for calibrating a charging current. A device may include a charger for conveying an output voltage to a chargeable device. The device may also include a monitoring system including an analog-to-digital converter for measuring a current received by the chargeable device. Further, the device may include a control device configured to receive a charging current value from the monitoring system and convey a signal to the charger in response to a comparison of the charging current value to a target current value.

Abstract: Systems and methods for determining a state of charge of a battery on a mobile device are disclosed. An exemplary method may include obtaining, when the battery is applying a level of current below a threshold level, an initial state of charge of the battery based upon a measured open circuit voltage value that is applied by the battery. Charge drawn from, and provided to, the battery is monitored from a time after the measured open circuit voltage value is obtained and a state of charge value is calculated when the battery is loaded after the initial open circuit voltage value is obtained based upon the monitored charge. An estimated open circuit voltage for the battery is calculated based upon simultaneous measurements of battery voltage and battery current, and a corrected state of charge value is generated using the estimated open circuit voltage.
