<b>Battery status notification</b>

Battery Monitor can show a persistent notification with up-to-date battery information. You can choose what is displayed, such as battery percentage, charging status, or additional details.

<b>Battery alarms</b>

Set practical alerts to help you manage charging and discharging. Battery Monitor can notify you when the battery reaches a selected level, drops below a chosen threshold, or becomes fully charged.

<b>History and export</b>

The app records battery-related events so you can review how your battery status changed over time. Logs can be filtered and exported to CSV for further analysis.

<b>Widgets</b>

Home screen widgets let you keep important battery information visible without opening the app.

<b>Privacy</b>

Battery Monitor does not collect, store, or transmit personal data. It focuses only on local battery monitoring on your device.

<b>Project background</b>

Battery Monitor is a continued and rebranded version of Battery Indicator Pro / BatteryBot Pro. The project aims to preserve a classic, clear battery monitoring experience while keeping the app working well on modern Android versions.

New:

- Added system (Android 13+) language chooser in settings (#56, thanks @Aga-C).
- Added importing and exporting app settings (#51, thanks @Hirdaya-Shrestha).

Fixed:

- Using localized unit strings instead of hardcoded English ones (#63, thanks @Hirdaya-Shrestha).
- Rewritten live updates to use NotificationCompat, to ensure it works well with API 36.
- Turned off force refresh of battery data in OS in the Advanced tab, which could cause issues with some battery drivers.
