Low Battery Alerts

On a battery powered device, such as a smartphone, it is important to alert the user when the battery is at a critically low level.

Audio notifications may be modified by the use of known DSP algorithms to help provide an indication to the user that the battery is low. For example, applying an audio distortion effect, such as a “slow gear” or a “phase shift” to ringtones could provide an indication that the battery is low.
