Description
Battery charging speed, watt meter, health and AOD in one app
AmpereFlow is a complete battery charging monitor that shows what happens after you plug in your phone. Measure charging speed in live watts and amps, check whether fast charging is active, view estimated battery health and capacity, monitor temperature, and see how long your battery may take to reach 80% or 100%.
Compare chargers, cables, power banks and USB ports using real battery data instead of relying only on the charging icon in your status bar. AmpereFlow combines live readings, detailed graphs, charge history, widgets, alerts and an AMOLED-friendly always-on charging display in one clean app.
Key Features:
⚡ Live Charging Speed: View real-time battery current in milliamps and estimated charging power in watts while your phone charges.
🚀 Fast Charging Detection: See whether your device reports normal charging, fast charging or another supported charging state.
🔌 Charging Speed Test: Test different chargers, cables, power banks and ports to find the setup that charges your phone most effectively.
⏱️ Time to 80% and 100%: Check estimated charge time so you know approximately when your phone will be ready.
🔋 Battery Health and Capacity: View estimated battery health, measured capacity and capacity loss based on the data available from your device.
📈 Battery Health Over Time: Follow your estimated health trend on a scrollable history graph instead of relying on a single reading.
📊 Detailed History Graphs: Tap supported statistics such as current, power, voltage or temperature to see how they changed over time.
📶 Charging Power by Battery Level: See how charging power changes as the battery moves from a low percentage toward full.
🕘 Charge History and Session Replay: Review previous charging sessions and inspect each session's charging curve.

🔔 Battery Level Alerts: Choose a target level and receive an alert when your battery reaches it.
🏠 Live Graph Widgets: Add current, power or temperature graphs to your home screen for quick access without opening the app.
🎨 Charging Animation and Speedometer: Customize the charging meter, clock, colours and statistics shown on screen.
📱 Always-On Charging Display: Keep charging information visible on a predominantly black, AMOLED-friendly screen on supported devices.
Designed for clearer battery readings
Battery data can vary between Android devices because manufacturers may report current, charge and voltage values using different scales or conventions. AmpereFlow applies device-aware corrections and consistency checks where supported to provide clearer charging estimates. Sensor availability and precision may vary by device.
Whether you are testing a new fast charger, diagnosing slow charging, comparing cables or following your battery's long-term condition, AmpereFlow puts the most useful battery information in one place.

So annoying that you need to agree or disagree to hundreds of advertisers before even using the app. Uninstalled. All I wanted was to see charge watts.
★☆☆☆☆goofy ahh· Aug 25, 2026
Insane amount of unnecessary ads. I initially just wanted to check something out about my battery and now i gotta watch through this whole entire ad.
★☆☆☆☆Sam Arnold· Aug 16, 2026
