In one aspect, a device (100) includes a processor (122) and storage (180). The storage includes instructions executable by the processor to determine, based on battery usage history data, a first state of charge (SOC) to which to charge a battery, with the first SOC being less than full SOC (830). The instructions are also executable to, based on the determination, charge the battery to a first voltage corresponding to the first SOC (840). The first SOC may include both a first charge amount equal to an estimated discharge amount for an upcoming discharge cycle, and a reserve charge amount in excess of the first charge amount (830). The battery may therefore be charged more than enough for the user to use the battery during the upcoming discharge cycle while still reducing the likelihood of accelerated battery degradation due to the battery being kept at full charge for too long.
