Maintaining the voltage of a consumer-device battery at near-maximum levels causes premature battery degradation. If kept fully charged for excessive amounts of time, the battery can swell, damaging the device enclosure and causing safety problems. However, users legitimately fear the draining of device batteries before a power socket is available, and hence keep devices plugged in beyond recommended durations.

The techniques of this disclosure monitor the availability of a power source, and accordingly set the maximum charge level such that battery life is optimized. For example, if power sources are amply available, the maximum allowed charge level is relatively low. If power sources are relatively scarce, the maximum allowed charge level is moved upwards.
