1. A computer-implemented method comprising:
- drawing, from a first battery cell of a device, load power to support a workload of the device;
determining that an efficiency at which the first battery cell is capable of powering a future workload is not optimal; and
charging, via a second battery cell of the device, the first battery cell effective to improve the efficiency at which the first battery is capable of powering the future workload.

Abstract
This document describes techniques and apparatuses of load allocation for multi-battery devices. In some embodiments, these techniques and apparatuses determine an amount of load power that a multi-battery device consumes to operate. Respective efficiencies at which the device'"'"'s multiple batteries are capable of providing power are also determined. A respective portion of load power is then drawn from each of the batteries based on their respective efficiencies.

15. A system comprising:
-
a first battery and a second battery configured to provide power to enable operation of the computing device; switching circuitry configured to enable the power to be drawn from each of the first battery and the second battery; sensing circuitry configured to measure load power consumed by the system to operate; and a load allocator configured to perform operations comprising; determining, via an algorithm and based on respective efficiencies of the first battery and the second battery, an allocation of load power being consumed by the system to the first battery and the second battery to maximize an efficiency at which the first battery and the second battery power the system; drawing, from the first battery, load power to support a workload of the system; determining, via the algorithm and based on the efficiency of the first battery, that an efficiency at which the first battery is capable of powering a future workload is not optimal; and charging, via the second battery, the first battery effective to improve the efficiency at which the first battery is capable of powering the future workload. - View Dependent Claims (16, 17, 18, 19, 20)
