Vizo: Battery Health Monitor

Vizo Battery is a battery health and charging monitor for Android. Track estimated battery health and capacity, measure charging speed, current, voltage, power and temperature in real time, compare chargers and cables, investigate battery drain, and review battery history with charts, alerts and Home Screen widgets.

BATTERY PLAN

Set a target time and choose the minimum battery level you want to keep. Vizo estimates whether your battery may last until your goal and, when needed, suggests when to recharge.

• Choose a target time and battery reserve
• Check whether estimated battery life is enough
• Get a smart recharge recommendation
• Plan ahead instead of waiting until the battery is almost empty

Results are estimates based on available battery data and observed usage.

BATTERY HEALTH & CAPACITY

• Track battery level and charging status
• Monitor charging and discharging behavior
• View temperature and battery information provided by Android
• See estimated battery health and capacity based on available device data
• Check estimated remaining battery time and time to full charge

CHARGING SPEED & POWER

• View charging current, voltage, estimated battery-side power and temperature in real time
• Compare chargers, cables and charging setups on the same device
• See average, minimum and maximum values during a live session
• Use the optional charging screensaver to keep key information visible

Values are reported by Android on the battery side and may differ from the charger’s rated output.

CHARGER LAB

Save real charging sessions and compare charging setups.

• Assign sessions to your chargers
• Compare charging speed, power and stability
• Review charger statistics and individual sessions

Results may vary depending on hardware, battery level, temperature and Android power reporting.

BATTERY DETECTIVE

Investigate recent battery drain using battery, activity and optional app-usage data from the last 12 hours.

• Review battery drop and average drain rate
• See screen-on time, screen-off time and battery temperature
• Identify apps whose activity overlaps with observed drain
• Review estimated battery usage and confidence levels when enough data is available

Battery Detective highlights correlations and possible contributors, not direct causation.

BATTERY USAGE & HISTORY

Explore battery history with charts for battery level, daily consumption and charging activity.

With optional Usage Access permission, Vizo can show app usage statistics and insights to help you understand how usage habits relate to battery consumption.

BATTERY CARE

Review how charging habits may affect battery stress over time.

• See a 7-day Battery Care score
• Review charging stress, heat and time spent at high charge levels
• Check exposure to 80%, 90% and 100%
• Review charging sessions and peak temperatures

BATTERY WIDGETS

Keep useful battery information visible without opening the app. Choose widgets for battery level, statistics, usage habits, battery health and more.

ALERTS & NOTIFICATIONS

Configure notifications for low battery, charging thresholds, full charge, temperature, charging activity and session summaries.

PRIVACY

Battery history, statistics, widget settings and preferences are stored locally on your device.
