HeadSet Battery Android app

Android Bluetooth HeadSet Battery app by CHI Software Android Unit displays the information about the charge level of the Bluetooth headset, headphones, and also AirPods. Periodically updating this product, the team is boosting skills with Bluetooth Low Energy (BLE) and Bluetooth, Bluetooth sockets, and AT commands.

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 have a battery indicator, 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.

Testimonials

The Android Headset Battery app is my brainchild! It was I who suggested the initial app idea and created the first app version. This exciting project allowed us to add helpful features not provided by Android. My team wanted to create an application that can monitor the charge of Bluetooth headsets or headphones and warn users about their low levels. Since we started back in 2015, we have been regularly updating the app, adding new devices like Apple AirPods, and features. I believe in the bright future of this app.
