About this app

⚡ Battery Charging Monitor is a real-time battery and charging monitor for device-reported charging speed in Watts (W) and milliamps (mA), charging sessions, temperature, level, and voltage.

See how much power and net current enters or leaves your battery while charging or discharging. Follow live battery statistics, test your charger speed, explore charging charts, and review locally recorded history in one place.

IMPORTANT: Wattage (W) and current (mA) values are device-reported net battery metrics, not direct measurements of charger wall output. Reading availability, update frequency, and accuracy depend on your device hardware, Android version, and manufacturer.

📈 LIVE CHARGING SPEED MONITOR (WATTS & mA)
• Measure device-reported charge and discharge speed in Watts (W) or milliamps (mA)
• Switch between Watt and mA chart views with a single tap
• Readings update approximately once per second when supported
• See minimum, maximum, and average power for the active session
• View live charging charts over 60 seconds, 10, 60, or 120 minutes
• Choose a smooth trend line or actual collected data points
• Check battery level, voltage, battery temperature, and Android plug type (AC, USB, Wireless, Dock)
• Session timer tracks time since you plugged in or unplugged
• Customizable ongoing notification with toggles for voltage, temperature, and elapsed time

🔬 CHARGING PROFILE BY BATTERY LEVEL
Analyze charging performance across ten battery-level ranges: 0-10%, 10-20%, up through 90-100%.
• Review average wattage (W) or current (mA) in each 10% range
• Find your peak charging speed and observe how charging tapers off as the battery fills
• Compare chargers and cables range by range to see if your 25W, 45W, or 65W fast charger delivers expected speeds
• Build long-term averages accumulated from retained charging sessions
• Session breakdown includes duration, average speed, peak range, and sample count

📜 CHARGING & DISCHARGING HISTORY
• Keep up to the 199 most recent charging and discharging sessions
• Track start and end battery level, duration, and recorded Watt / mA range
• Visual level track shows where each session began and ended
• Dynamic status updates live while monitoring is running

🔋 BATTERY INFORMATION & HEALTH
Battery Charging Monitor displays data reported by Android and your device hardware. Depending on manufacturer support, information may include battery technology, Android-reported health condition, and available RAM. Unsupported rows are hidden rather than guessed.

⚙️ PERSONALIZE YOUR BATTERY MONITOR
• Dark, Standard Dark, light, or system theme
• Teal or blue accent color
• Celsius (°C) or Fahrenheit (°F)
• High charge limit alerts to help protect battery health
• 18 languages, including right-to-left Arabic
• Core battery monitoring works offline
• Optional auto-restart after reboot (background operation may be subject to device settings)

🔒 PRIVACY
Your battery data stays on your device. Recorded measurements and session history are stored locally and never uploaded to external servers. No account, location permission, or storage permission required. Google services provide ads, analytics, and crash reporting as outlined in the privacy policy.

Requires Android 9.0 or newer.

Paid for no advertisements. Some how the app got uninstalled and now all I have is the non pro version??? Can not find the pro version. Just uninstalling not it's not worth my time if I can't get rid of the commercials I don't need it. So odd I have the app on two phones and one plays advertising and one doesn't. Same account for both devices. The link to rate the application goes a dead end when leaving from the application to the play store. Please reply.

I can find no way to disable the graph and it uses the cpu and therefore the battery. Otherwise it's okay, except for the high cost of 3 usd to disable ads. Ampere was $1 and a few cents so I bought it. This app should cost no more than 1.99 usd. Also, disappointingly, it doesn't show estimated time to completion of full charge within the app, just a link to the Android system's battery info page. .

Would be perfect if it didn't lose the history when it disconnects. As it is if you have a bad cable it deletes everything and starts over. I'd rather see it go from charging to discharging and know how much it was discharging when it was unplugged as well. That would make it alot easier to compare one charger to another. Now, you have to remember how much the last charger put out in order to compare it to the new one.. You should be able to look at the history & compare the last several.
