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

📈 Charts

► The changes in a graph over the past days
► Configure the graph by choosing level, temperature and voltage alone or in two graphs together
► Separate graph for battery current

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 In this case, the widget is no longer updated, notifications are not sent, and no data is logged.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.

Ratings and reviews

There's only a few issues. With android 14, the app icon feature in the notification area won't show, it only shows the app's icon itself. It works fine on my older android 13 phone. It would also be nice to change the notification area from light to dark theme independently from the phones theme, because when using most samsung themes it forces light mode on the phone, which also forces the notification for this app to be white as well and it doesn't always look the greatest. The rest is great!

I love this app! it does everything that I need it to do; monitors the temperature & alerts me if it's overheating, tells me how fast it is charging, & prevents overcharging of the battery (still don't understand that whole concept!). I've used it for years and it gets better and better, EXCEPT: when you open the app, it used to show the percentage of battery charge in larger numbers so that it was really easy to see. I miss that a lot. I didn't have to put my glasses on to read it.

This is exactly what I'm looking for but I only wish the notification status is permanent and cannot be swiped. Update: The dev made an update, although it's just a workaround but I'm very satisfied with the result. Thanks for this great app!!
