Electronic Device With Improved Power Management
First Claim
1. An electronic device configured to receive power from an external power source, comprising:
- a battery configured to be charged;
a battery gauge coupled to the battery that measures a state of charge of the battery;
a charger circuit configured to receive power from the external power source and to charge the battery using power received from the external power source; and
control circuitry coupled to the battery and configured to;
run a plurality of processes;
receive a state of charge measurement measured using the battery gauge;
upon receiving the state of charge measurement measured using the battery gauge, disconnect the battery from the charger circuit while the charger circuit receives power from the external power source; and
stop at least one process of the plurality of processes while the battery is disconnected from the charger circuit and the charger circuit is receiving power from the external power source.

Abstract
An electronic device may have a power system with a battery. The power system receives power such as wireless power or wired power and uses a portion of the received power to charge the battery as needed. Control circuitry in the portable electronic device is used to run background processes such as image processing tasks, data synchronization tasks, indexing, and other background processes. In some circumstances, such as when the battery is below a certain state of charge threshold, background processes may be stopped so that the battery is charged as fast as possible. Once above this initial state of charge threshold, background processes may be performed during charging as long as the temperature and state of charge of the battery do not exceed safety temperature and safety state of charge values. Performing background processes in these conditions ensures requisite background processing tasks are completed while preserving battery health.
