Monitor charge thresholds, temperature, and long-term trends with Battery Alarm Pro - Full Low, which issues customizable full, low, and overheating alerts. Developed by CloudEx Inc., the app combines real-time technical readouts (voltage, current, power) with voice and visual alarms, quiet hours, and widgets. It fits Android users who follow charging routines like the 20-80% rule and want persistent logs and non-repetitive alerts without constant interaction.

What does Battery do and how does it operate?

Battery tracks the device battery state and connected Bluetooth earbud levels, producing alarms for full charge, low battery, and high temperature. The tool offers voice alerts via text-to-speech, eleven built-in sounds, custom music, vibration patterns, and camera flash notifications. Charge history and level charts retain data for up to 400 days, and a "once per charge" logic prevents repeated alerts within the same charging session.

Does it slow down your device during monitoring?

The app is designed for background operation with minimal drain: the source states the app has a small runtime footprint and operates efficiently in the background. Real-time metrics include voltage, current (mA), and power (W), so the tool polls battery sensors regularly while claiming low overhead; users should expect some sensor polling but not a continuous heavy CPU load.

Is it safe to run and does it require special permissions?

The app provides readouts and alerts without describing direct writes to system files; it reads battery telemetry and can trigger notifications and camera flash. It supports quiet hours and a pause function to suppress sounds. The app's behavior on some manufacturers requires manual battery optimization adjustments, so users on those devices must allow background activity for consistent alerts.

Who should use Battery and what limitation to expect

Battery suits Android owners who deliberately manage charge windows and want long-term battery health data, offering persistent logs and multiple alert channels. The one significant limitation is that certain manufacturers require manual battery optimization changes for reliable background operation, which adds a setup step for affected devices.
