Bluetooth Battery App Development for Android

Project background

One of the reasons people face battery drain issues might be because of the many music apps they may be streaming. Streaming apps use a lot of data and screen time so that the battery may discharge quickly. Some headsets don’t display the Bluetooth battery level on Android, which causes inconvenience to users. 

Android Bluetooth HeadSet Battery app is not a commercial one, but rather a demonstration of our developers’ skills and expertise. It belongs to a rich collection of CHI Software’s internal products. 

The main idea of the app was to report on the status of the battery and warn the user about the low battery charge in advance. This Android mobile application, created by CHI Software Android Unit, displays the information about the charge level of the Bluetooth-headsets, headphones, and AirPods. 

Business needs

One of the reasons people face battery drain issues might be because of the many music apps you may be streaming. Streaming apps use a lot of data and screen time, so your battery may discharge quickly. In this situation, the question of how to see a headphone battery on Android stands out sharply.  

– Our development team offered an effective way to measure the remaining charge on your Bluetooth remote device.  

– The main idea behind our Bluetooth headset app development was to report on the battery’s status and warn the user about the low battery in advance.  

– Our team wanted to boost skills with Bluetooth Low Energy (BLE) and Bluetooth technologies. 

Product features

1. Connection of high level Bluetooth-headsets. Those headsets send 10 states of battery charge with 10% interval of the battery charge and a headset model
2. Connection of medium level Bluetooth-headsets. Those headsets send 4 states of battery charge – they are 100%, 70%, 30%, and 0% of battery charge, and a headset model
3. Connection of low level Bluetooth-headsets. Those headsets don’t send any states of battery charge, but the headset model only
4. Convenient battery indicator
5. Location of the last device connection
6. Support the display of 2x and more devices
7. Report on the status of the battery
8. Warning about the low battery in advance
9. Work with all Bluetooth headphones and Apple AirPods

Solution

CHI Software Mobile Unit developed a Bluetooth battery app where all the necessary information is displayed on the screen of the user’s phone. The app also keeps a history of connection and disconnection, so future versions will predict the time of the headphones’ work.
