About this app

This app is designed to alert you on too high or too low battery temperature. Prevent your phone's battery from overheating or freezing by receiving a notification if its temperature exceeds a limit. Additionally, receive notifications on low battery level, and configure an alert level while charging to protect your battery from overcharging.
The app collects and visualizes different data about your battery and the charging process, showing statistics and charts.

A simple, lightweight version of this app, without all the statistics and charts is available here: https://play.google.com/store/apps/details?id=dev.bytesculptor.batterytemperaturestatus

Although the app has to run permanently in the background to operate reliably, it has a very low energy consumption. On all our test devices it is less than 0.5%.

The operating system sometimes stops the app. In this case, the widget is no longer updated, notifications are not sent, and no data is logged. To prevent this, Bamowi should be excluded from any battery saver app. If you use a task-killer app, Bamowi must be excluded to work properly.

Some manufacturers restrict heavily apps in the background. It is possible that this app doesn't work reliably on some models from Samsung, Oppo, Vivo, Redmi, Xiaomi, Huawei, and Ulefone. Please check the Help section of the app for further instructions.
