Battery Ampere Monitor

🪫 Battery Ampere Monitor – Check Battery Charging & Discharging Current

⚠️ Disclaimer
Battery Ampere Monitor uses software-based algorithms to estimate your device’s charging and discharging current.
👉 All values are for reference only and should not be considered exact or laboratory-grade measurements.
The app does not collect or share any personal data.

🔋 Key Features

• Battery Information: View voltage, temperature, health, capacity, and charging status.
• Live Current Monitor: See real-time charging and discharging current (mA).
• Charging Graph: Visualize current stability and fluctuations over time.
• Battery Health Estimate: Compare remaining capacity versus original (for reference only).
• Broad Compatibility: Works on most Android devices, including various Chinese brands.

🧠 How It Works

When not charging → shows discharge current (negative value).
When charging → shows charging current (positive value).

Example:
If your phone uses -300 mA when idle and your charger provides 500 mA, the app will show around +200 mA.

Results depend on:

Charger type (USB / AC / Wireless)

Cable quality

Device hardware & firmware

Screen brightness, GPS, Wi-Fi, and background activity

⚙️ Technical Notes

• Not all devices support current measurement — some lack the required sensors or APIs.
• If you see 0 mA readings, try enabling “Old Measurement Method” in settings.
• Current readings are averaged from 50 samples (with top 10 and bottom 10 filtered).
• Some phones (e.g., Galaxy S5) may only show estimated maximum current due to firmware limits.

🚫 Important Notice

Battery Ampere Monitor is not a professional diagnostic tool.
Use it to compare charger and cable performance on the same device — not for precision battery analysis.

🧩 Summary:
Real-time battery current tracking. Understand your charging speed and battery behavior with clear, reference-based readings.
