Charge Manager

Charge Manager is a real-time battery monitor, charging speed tester, and battery telemetry tool. Whether you want to test if your charger and USB cable are delivering their optimal charging rates, monitor battery drain caused by background apps, or protect your device from overheating and overcharging stress, Charge Manager gives you accurate hardware-level insights. ⚡ Real-Time Charging & Discharging Telemetry • Live Power Meter: View live current in Milliamperes (mA) or derived Power in Watts (W) with a single tap. • Accurate Diagnostics: Monitor real-time Voltage (V), Battery Temperature (°C / °F), and Battery Level (%). • Time Remaining: Precise calculations for time until fully charged (when plugged in) or time until empty (on battery). • Telemetry Statistics: Track minimum, maximum, and average current rates throughout your session. 📈 Charging Curves & Session History • Visual Power Curves: Observe how your charger delivers power over time with smooth power curves. • Fast Charge Taper Analysis: Inspect real-time power drop-offs as your battery reaches higher percentages. • Session Summary: View total energy transferred (in mAh), duration, start and end battery levels, and peak wattage for every charge. • Compare Hardware: Review session history to compare different chargers, cables, power banks, and wireless pads. 🔍 App Battery Drain Monitor • Identify Power Usage: Pinpoint which installed apps consume energy in the background and foreground. • Discharge Rate Breakdown: Monitor per-app battery impact in percentage and active mA discharge speed. • Optimize Usage: Detect unnecessary background consumption to help extend your daily battery runtime. 🛡️ Smart Battery Protection Alarms • Target Charge Alarm: Set a custom charge level alert (such as 80% or 85%) to avoid high-voltage stress and help preserve lithium-ion battery longevity. • High Temperature Overheat Alarm: Receive instant notifications if battery temperature exceeds safe limits during fast charging, intensive gaming, or warm conditions. • Low Battery Warning: Get reminded before your device drops to critical shutdown levels. • Customizable Notifications: Select alarm tones, preview sound, adjust volume, and toggle vibration. 📱 Home Screen Widgets Keep essential battery telemetry visible right on your home screen: • 1×1 Current Widget (Live mA / Watts) • 1×1 Battery Level Widget • 1×1 Temperature Widget • 1×1 Voltage Widget • 2×2 All-in-One Combo Widget (Current, Level, Temperature & Voltage together) 🔬 Hardware-Level Measurement & Accuracy Charge Manager reads telemetry directly from your device's built-in OEM battery fuel-gauge systems and Android hardware sensors. The app displays real hardware telemetry without exaggerated numbers or artificial metrics. 🔋 Designed for Efficiency • AMOLED Dark Theme: Clean, high-contrast user interface designed to be easy on your screen and battery. • Lightweight Background Service: Optimized background telemetry with minimal CPU overhead and zero unnecessary wake-locks. • Clean Experience: Built purely for utility, accuracy, and transparent battery telemetry. Test your chargers, monitor battery telemetry in real time, and protect your battery longevity with Charge Manager.
