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 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, battery 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 monitoring session • Use the optional charging screensaver to keep key charging information visible Values are reported by Android on the battery side and may differ from the charger’s rated output. COMPARE CHARGERS – CHARGER LAB Save real charging sessions and compare chargers and charging setups on your device. • Assign charging sessions to your chargers • Compare charging speed, power and stability • Review sessions and charger statistics • Reassign or remove sessions when changing your setup Results may vary depending on hardware, battery level, temperature and Android power reporting. BATTERY DRAIN – 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 the observed drain • Review estimated battery usage and confidence levels when enough data is available Battery Detective highlights correlations and possible contributors, not direct causation, because Android does not expose complete per-app battery measurements on every device. BATTERY USAGE & HISTORY Explore battery history with charts for battery level, daily consumption and charging activity. With optional Usage Access permission, Vizo Battery can show app usage statistics and insights to help you understand how usage habits relate to battery consumption. BATTERY CARE & CHARGING HABITS Review how your 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% charge levels • Review charging sessions and peak temperatures Battery Care becomes more useful as more charging-session data is collected.
