Battery Care
Smart Health, Voice Alerts & Li-ion Protection
Keep your smartphone battery at peak efficiency. Real-time charge velocity telemetry (+%/hr), voice milestone announcements, intelligent 20%-80% healthy habits, and granular charging cycle logs.
Smart Telemetry & Live Health
Instant access to real-time charge velocity (+%/hr), active discharge rates, Li-ion millivolt telemetry, and internal battery temperature.
Engineered for Maximum Battery Lifespan
Modern smart battery telemetry to give you full visibility over your phone's power subsystem.
Real-Time Charge & Drain Velocity
Accurately measures real-time energy flow in percentage per hour (+%/hr or -%/hr) to diagnose fast-charging speed.
20% - 80% Healthy Charging Habit
Helps you avoid high voltage stress above 80% and deep depletion below 20%, doubling your Lithium-Ion battery cycle life.
Spoken Voice Milestone Alerts
Hands-free voice alerts inform you when your battery hits 80% or finishes charging without needing to check your screen.
7-Day Timeline Session Logs
Inspect past charge events, duration, speed percentage, and detect overheating or slow charging adapters.
Intelligent Quiet Hours (DND)
Schedule sleep windows so voice alerts stay silent at night while you sleep peacefully.
100% Privacy & Zero Background Harvest
Runs entirely on-device. No telemetry servers, no location access, and no personal data collection.
The Science: Why 20% to 80% Charging Matters
Modern smartphones use Lithium-Ion / Li-Po chemistry. Keeping batteries between 20% and 80% minimizes chemical degradation and prevents rapid battery capacity loss over time.
Reduces High Voltage Stress
Charging above 80% forces the battery cells into high-voltage saturation, accelerating electrolyte oxidation.
Prevents Deep Discharge Damage
Discharging below 20% stresses the anode and increases internal resistance, causing permanent capacity loss.
Up to 3X More Charge Cycles
Studies show partial cycle charging (20%-80%) can extend battery longevity from ~500 full cycles to over 1,500 cycles.
Extend Li-ion Longevity
Protect your phone against high-voltage saturation with spoken 80% unplug reminders.
Zero Background Telemetry
Your battery telemetry, charging logs, and device data never leave your phone. Battery Care contains zero analytics trackers and requires zero account sign-up.
