About this app

AmperePro – Cable & Charger Tester is a smart diagnostic tool that helps you measure charging speed, detect weak cables, test power adapters, and solve slow charging problems in seconds. If your phone charges slowly, overheats, or drains fast, AmperePro identifies the real issue instantly using accurate current and voltage analysis.

⸻

🔌 Cable Test – Check USB Cable Quality

Many charging issues come from cheap or damaged cables. AmperePro helps you test cable quality by measuring real electrical performance:

• Cable quality score
• Real-time charging current (mA)
• Voltage stability test
• Slow charging detection
• Power fluctuation alerts

Use this test to identify weak, broken, or fake cables that fail to support fast charging.

⚡ Adapter/Charger Test – Detect Fake or Weak Chargers

Not all chargers are equal. Some chargers claim to support fast charging but don’t deliver enough output. AmperePro helps you verify:

• Charger output power (mA & Voltage)
• Fast charging support
• USB Adapter Type (USB/AC/Wireless)
• Power drops & fluctuations
• Unsafe or low-quality charger alerts

This is perfect for checking if your 18W/30W/45W/65W fast charger is working properly.

🔋 Charging Speed Measurement

Measure how fast your device actually charges — not just what the charger claims.

• Live charging speed (mA)
• Voltage reading (V)
• Estimated time to full charge
• Battery temperature monitoring
• Discharging current when unplugged

See the difference between fast charging vs slow charging in real time.

🛠 Fix Slow Charging Problems

AmperePro helps you find out what’s causing slow charging:

• Weak or damaged cable
• Low-quality adapter
• USB port issues
• High background usage
• Battery health problems
• Device heating issues

If your device charges slowly sometimes and fast at other times, AmperePro lets you compare different Cable + Charger combos.

📊 Battery Behavior & Technical Accuracy

The app measures charging and discharging current directly from system interfaces when supported. If your phone is not charging, you will see a negative value (battery drain). When charging, the value represents actual current entering the battery after the phone’s self-consumption is deducted.

Example:
If your device consumes -300 mA on screen-on, and your charger outputs +1500 mA, AmperePro may display +1200 mA charging current.

Charging speed depends on many factors:

• Charger type (USB, AC, Wireless)
• USB cable quality
• Display brightness
• Background tasks
• WiFi & GPS usage
• Battery temperature
• Phone model and firmware

Due to Li-Po battery chemistry, charging current naturally decreases near 80–100% battery level.

⚙️ Device Compatibility

Not every device provides accurate readings because some phones lack the required battery measurement interface. On unsupported devices, values may show 0mA or unstable readings. This is a hardware/firmware limitation, not an app fault.
