Chargewise shows how your battery is really doing and how you charge it. One screen answers what is happening now, how healthy your battery is and what to do next. Watch live power while charging, see when it reaches 80 % and full, follow an honest health estimate and get a loud alarm when it is time to unplug.
BATTERY AT A GLANCE
• Live ring with level, power and a plain word for the speed: slow, normal, fast
• 80 % at 22:12, full at 22:49: clock times while charging, and how long the battery should last on battery (estimates)
• One-tap alarm at 80 % and a heat alert, right on the main screen
• Health, temperature, cycles and voltage tiles, each with a short verdict
• This charge so far: time, % and mAh added, peak power and highest temperature
• Bedside view: a dark, dim screen with the level and times while charging at night
EVERY CHARGE, SAVED
• Each plug-in becomes a session with level, mAh, energy (estimated), power and temperature
• Charge curves with the charging phases marked: fast, topping off, trickle, held by your phone or slowed by heat
• A charge score from 0 to 100 for how gently each charge went, with the reason
• Compare two charges side by side; discharge use per hour with the screen on and off
BATTERY HEALTH, HONESTLY
• Learns your battery's capacity from your normal charges, shown as a range with a confidence level
• Health trend over time and a lifetime projection as a range, once there is enough data
• Wear meter, cycle count and battery facts from Android when your phone reports them
INSIGHTS
• Weekly battery report you can share as an image
• Charger lab: a 60-second speed test with a verdict, your chargers and cables compared side by side
• Charging habits: plug-in levels, time at full charge, heat, and a habit score with simple tips
• Which apps used the most battery (estimate, needs usage access)
ALARMS AND ALERTS
• Alarm at any level, several levels, and a real "fully charged" alarm; loud sound, repeat, quiet hours
• Presets: stop at 80 % or charge to 100 % for travel
• Alerts for high temperature, low battery, unplugging early and unusual battery drain
• A summary when you unplug: how much was charged, how fast and how warm
• Optional live notification with level, power and temperature
HONEST BY DESIGN
• Every value is marked as measured, estimated (method explained) or not available on your phone
• Gaps in history are shown as gaps, never filled with guesses
WIDGETS, TILE AND EXPORT
• Widgets for the live gauge, last charge and health; a Quick Settings tile; CSV export
PRIVATE BY DESIGN
• No account, no sign-up, no location. Your battery history stays on your phone
• No ads
• Light and dark themes, accent colours, °C or °F, 18 languages, tablets
GOOD TO KNOW
• Android does not let apps read the battery health % some phones show in Settings, so Chargewise estimates it and says how sure it is
• No app can stop charging or repair a battery. Chargewise measures and alerts
• Without the live notification, Android lets apps check the battery only from time to time, so a background alarm can be a few minutes late
PERMISSIONS
• Notifications: for the alarms, alerts and live notification you turn on
• Usage access (optional): only for the per-app battery estimate, explained before you grant it
