Battery Lens: Charge Monitor

Battery Lens is a private battery monitor that turns Android battery readings into clear, useful guidance. Check charging power, temperature, voltage, current, charge time and battery condition without ads, accounts or tracking. MEASURE YOUR BATTERY • Live charging monitor: See charge level, power, current, voltage, temperature and power source in one calm dashboard. • Battery health insights: Understand Android-reported condition, cycle count and heat warnings without misleading “repair” claims. • Charge history: Review completed charging sessions, level gain, duration and peak temperature. • Capacity learning: Build an evidence-based capacity estimate from valid charging sessions, with an honest confidence rating. CHARGE WITH CONFIDENCE • Charge target alarm: Choose a target from 60% to 100% and get notified when it is reached. • Temperature alert: Receive a warning when charging becomes hotter than your chosen limit. • Lock-screen progress: Follow quiet ongoing charging progress with percentage, power, temperature and estimated time remaining. • 10 charging animations: Swipe between Liquid, Wave, Particles, Dual Flow, Neon, Burst, Segments, Radar, Halo and Power Bars. PRIVATE BY DESIGN Battery Lens has no internet permission and includes no advertising, analytics, attribution or crash-reporting SDK. Battery readings, preferences and charge history remain on your device. You can clear local history whenever you want. HONEST AND EFFICIENT Hardware support varies by Android device, so unavailable measurements are clearly marked instead of invented. Battery Lens does not claim to repair a battery, accelerate charging, stop charging through software or control hardware it cannot access. Background checks run only while charging and use Android’s recommended scheduler. Everything is free. There are no ads, subscriptions or in-app purchases. Download Battery Lens for a focused battery health monitor, charging alarm and private charge history in one lightweight utility.
