Overview

BatteryPro is a modern, privacy-focused battery utility designed to help users extend the lifespan of their device's lithium-ion battery. With instant charging rate telemetry, intelligent high/low alarms, temperature tracking, and capacity health scores, BatteryPro gives you complete visibility over your device's power subsystem.

Features and Why They Matter

Real-Time Charging Telemetry. View live electrical current (mA), wattage (W), voltage (mV), and charging speed estimates with zero lag.
Smart Charge & Discharge Alarms. Set custom thresholds (like 80% to preserve cell health or 20% for low battery warnings) with audible notifications.
Battery Health & Capacity Estimation. Calculate degradation and estimate retained capacity versus the factory design specification.
Thermal & Overheating Protection. Monitor cell temperature continuously to avoid battery-degrading heat during rapid or wireless charging.
Offline Charging History. Log session durations, start/end levels, and power consumption privately on your device.

Privacy-First & Zero Tracking

BatteryPro runs 100% locally on your smartphone. We do not require account logins, we never collect device identifiers, and battery telemetry never leaves your device.

Minimal Battery Overhead

Unlike background-heavy battery monitors that consume significant power themselves, BatteryPro utilizes event-driven Android platform broadcasts to maintain exceptional energy efficiency.

Frequently Asked Questions

Does BatteryPro drain my battery while monitoring?

No. BatteryPro is built with an ultra-lightweight offline architecture that relies on passive OS broadcast events to ensure near-zero CPU and energy impact.

Can BatteryPro sound an alarm when my phone reaches 80% charge?

Yes. BatteryPro lets you set customizable charging thresholds such as 80% or 85% to protect lithium-ion cell longevity, as well as full-charge and low-battery warnings.
