Description
WattMate is the ampere meter and charging meter that shows you exactly what's happening when your phone charges. See real charging power in Watts, live voltage, current, and temperature — all updating in real time.
⚡ CHARGING POWER METER Know your actual charging wattage, not just a percentage bar.
- Live charging power display in Watts (W) - Ampere meter: charging current in milliamps (mA) - Battery voltage in volts (V) - Charger test: find your fastest charger and USB cable combination - See if your phone is fast charging or trickle charging - Charge speed test to compare adapters, cables, and wireless chargers
🌡 TEMPERATURE & BATTERY HEALTH Keep your battery healthy and out of the danger zone.
- Real-time battery temperature monitoring - Battery health status (Good / Fair / Poor) - Charging state: AC, USB, Wireless, or unplugged - Temperature alerts to protect against overheating
📊 LIVE GRAPHS Watch your charging stats over time, not just a snapshot.
- Real-time power graph while charging - Current and voltage trend over session - Spot fluctuations caused by charger, cable, or background apps
🔍 WHAT AFFECTS YOUR CHARGE SPEED? Your charging speed depends on many real-world factors: - Charger type (AC adapter, USB-C, wireless) - USB cable quality - Phone model and chipset - Apps running in the background - Screen-on vs screen-off state - Current battery level (charging slows near 100%)
WattMate reads directly from your device's battery controller for accurate, science-based readings — no guesswork, no false claims.
WHY WATTS MATTER Most ampere apps show you milliamps (mA). WattMate goes further: Power (W) = Voltage × Current. That means you see the true charging power, which is what actually determines how fast your battery fills up. A 5V/2A charger and a 9V/1.5A charger can both show ~2000mA but deliver very different charging speeds. WattMate shows you the difference.
🧪 BATTERY TESTER & CHARGER CHECKER Use WattMate as a battery tester and charger checker: - Test any charger or cable in seconds - Compare charging speed between wall adapters - Check if a cable is limiting your charge speed - Verify wireless charger output
CLEAN & SIMPLE No bloated features. No fake battery "cleaners" or "optimizers". WattMate does one thing: give you accurate, real-time charging and battery data that you can actually trust and act on.
Works on Android phones and tablets. Results depend on hardware support — most modern Android devices are fully supported.
