APK source:
icon Beam is a lightweight battery monitor. It pins a live power, current, voltage, or charge readout to your status bar and opens into a full breakdown of battery metrics inside a clean, themeable app.

Pick which unit appears in the status-bar icon (W, A, Ah, V, Wh, °C, %), or stack several values in the notification body.

Privacy first:
• No ads
• No tracking
• No data collection
• No third-party sharing
• No unnecessary permissions

Battery metrics in the app:
• Power (watts)
• Current (amps)
• Voltage (volts)
• Energy (watt-hours)
• Temperature (°C)
• Charge level (percent)
• Charging status and plug type
• Charging since (date / time)
• Time to full charge

Personalisation:
• Material You dynamic colour (Android 12+) or a custom seed colour from a 12-swatch palette
• Light, Dark, System, and OLED-black themes
• Optional hero backlight glow and haptic feedback

Device compatibility:
• Power-scalar correction for phones that report µA instead of mA
• Inverted-current toggle for phones that flip charging direction
• Adjustable polling interval

While you can download the APKs here directly, you should preferably use an F-Droid client so the app stays up-to-date on your device.
