Battery Health: Charge Monitor

Battery Health keeps an eye on your phone's battery so you don't have to. See how healthy it is, what's draining it, and get a nudge when it's time to unplug. AT A GLANCE • Battery level, charging or draining, and how fast. • Time to full while charging, time left while on battery. • Temperature, voltage, battery type and charge cycles (where your phone reports them). BATTERY HEALTH • Estimated capacity compared with the battery's original capacity. • A health figure that builds up as the app watches a few full charges. • Temperature history and Android's own thermal levels explained in plain words. WHAT DRAINS YOUR BATTERY • Drain rate overall, overnight, with the screen on and with it off. • Battery level history for the last 24 hours or 7 days. • Every charge session: when, how long, and from what level to what level. • App usage and screen time by day and by hour (needs Usage access, which you can allow or skip). ALERTS YOU CHOOSE • Charge limit: get told when the battery reaches your chosen level, for example 80 %. • Low battery and overheating alerts. • A weekly battery summary. WIDGETS • Five home-screen widgets: classic, minimal, ring, screen time and temperature. TIPS • Simple checks for brightness, dark mode, screen timeout and battery temperature, with a shortcut to the right setting. PRIVATE BY DESIGN • No account needed. • Your battery history and app-usage figures are worked out and kept on your phone. BATTERY HEALTH PRO Go Pro to remove all ads and open every report. Choose a subscription or a one-time lifetime purchase; prices are shown in the app before you buy, and subscriptions renew until you cancel in Google Play. GOOD TO KNOW • The app doesn't control charging: a charge-limit alert tells you when to unplug. • Health and capacity are estimates and depend on what your phone reports. • Some phones stop background apps to save power; allow Battery Health to run so alerts arrive on time.
