1. A method for managing power distribution in a device, comprising:
- determining a first power level of a first battery of the device;
determining a second power level of a second battery of the device;
adjusting an input current limit of a system charger based on the first power level and the second power level; and
steering power from one or both of the first battery or the second battery to at least one processor of the device based only on the input current limit, with the input current limit controlling which of the first battery, the second battery or both the first battery and the second battery is drained from and how much power is drained from the first battery, the second battery or both the first battery and the second battery.

9. A computer device for managing power distribution in a device comprising:
-
a first processor; a second processor; and a memory coupled to the first processor and the second processor, the memory including instructions executable by the first processor or the second processor to; determine a first power level of a first battery of the device; determine a second power level of a second battery of the device; adjust an input current limit of a system charger based on the first power level and the second power level; and steer power from one or both of the first battery or the second battery to one or both of the first processor or the second processor of the computer device based only on the input current limit, with the input current limit controlling which of the first battery, the second battery or both the first battery and the second battery is drained from and how much power is drained from the first battery, the second battery or both the first battery and the second battery. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
