Battery Sound Notification is a free utility application from developer Argon Dev. It's a tool that lets users create custom notification alerts that correspond to their device's battery level. They can set it for any percentage they want and use any audio file they have using the app.

Compared to other battery status apps like Battery Level for Status Bar or Battery Status Monitor that inform users of users through visual indicators, Battery Sound Notification provides a truly unique solution to users by using sound. Everything is configurable through a simple and intuitive user interface.

Audible battery tracking

Smartphones keep getting more powerful but people still have cold sweats when they realize their battery has dropped so low without realizing it. Battery status indicator apps make it easier to visually keep track of power levels yet users still forget to charge. Enter Battery Sound Notification, which takes a different approach with the use of auditory cues.

The standard options within this app allow you to add sound alerts for when batteries are low or full, charging or discharging, and plugged or unplugged. You can also set custom alerts for any percentage using whatever audio file you have. What’s more, repeating notifications are possible in case of situations when you were not able to catch the first one.

If you're on silent/vibrate mode, you can still have persistent alerts on, as well as an option to suspend the service if you don't want to be disturbed during specific times of the day or when you're on a phone call. One thing that needs to be added in future updates is the ability to control volume levels separately instead of everything tied to your media e.g. loud alerts.

Hear your battery

Overall, Battery Sound Notification is a novel idea that was executed well and works as advertised. It's easy to use, supports customizable percentages, and lets you set any custom audio you want. The only knock against it is its odd decision to link volume adjustment to your media. Aside from that, though, there's really no reason not to give it a try.
