Mobile devices such as smartphones can be configured with a variety of ringtones. Ringtone settings are agnostic of battery status. A rich ringtone that comprises a wide ensemble of musical instruments and has a high peak-to-average ratio causes the amplifiers and speakers of the device to drain the device battery. This disclosure describes techniques to automatically generate and select ringtone variants based on battery level. The ringtone variants share melodic structure and are readily recognizable as indicative of a call or message. When the battery level is high, a full ringtone is used that is energy intensive and aurally pleasing. At lower battery levels, ringtone variants are used that consume lesser energy yet share melodic structure with the full ringtone.
