The disclosed embodiments provide a system that manages use of a solid-state battery in a portable electronic device. During operation, the system monitors a temperature of the solid-state battery during use of the solid-state battery with the portable electronic device. Next, the system modifies a charging technique for the solid-state battery based on the monitored temperature to increase a capacity or a cycle life of the solid-state battery. To modify the charging technique based on the monitored temperature, the system may increase a charge rate of the solid-state battery if the temperature exceeds a first temperature threshold. On the other hand, the system may maintain the charge rate of the solid-state battery if the temperature does not exceed the first temperature threshold.
