Battery Health: Charge Monitor

Battery health, temperature, charge alerts and app usage, with home widgets.

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.

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.
