Charging Speed: Battery Meter

How fast is your phone charging? What happens to your battery when you unplug it?

Charging Speed: Battery Meter helps you monitor charging current, battery drain, power, voltage and temperature in one clear dashboard. Follow live readings, view charging graphs and review previous sessions to understand your phone’s battery activity.

CHECK YOUR CHARGING SPEED

See device-reported charging current in milliamps (mA), estimated battery power in watts (W) and battery voltage (V). Watch the readings change as your phone charges, alongside its battery percentage and estimated time to full.

Wondering why charging seems slow? Compare readings with different chargers and USB cables on the same phone. For a more useful comparison, keep battery level, temperature, screen brightness and phone activity similar.

FOLLOW BATTERY DRAIN

Unplug your charger to monitor discharging speed. See how the battery’s current draw changes while you use your phone, helping you understand its overall power demand.

This is battery-level monitoring, not a breakdown of power consumption by individual apps.

VIEW LIVE CHARGING GRAPHS

Follow the live charging curve instead of relying on a single number. See changes in current over time and switch between speed and battery-percentage views.

REVIEW CHARGING HISTORY

Keep track of saved charging sessions, including changes in battery percentage and session duration. Review the weekly charge-added chart to see your recorded charging activity over time.

CHECK BATTERY INFORMATION

Find useful battery details together:
• Battery level and charging status
• Charging and discharging current
• Estimated power and battery voltage
• Battery temperature
• Charger connection type
• Available capacity, technology and condition information

The details available depend on what your device reports.

SET CUSTOM BATTERY ALERTS — PRO

Choose a target battery percentage for a charge alarm, or set a temperature threshold for an overheat warning.

These alerts help you decide when to check your phone or unplug your charger. They do not automatically stop charging or cool the battery.

MAKE YOUR MONITOR YOURS

Choose light, dark or system appearance and personalize the interface with color presets. Add the battery widget to your home screen for convenient access to battery information.

UNDERSTAND YOUR READINGS

Charging Speed uses battery information available from your Android device. Supported measurements, update frequency and accuracy vary by phone and manufacturer.

Current and power readings describe battery-side activity and may differ from your charger’s advertised wattage or a USB power meter. Screen use, background activity, temperature and battery level can all affect the readings. Charging-time estimates can change as conditions change.

Capacity or condition information should not be treated as a laboratory battery-health test. This app monitors battery activity; it does not boost charging speed, repair batteries or extend battery life automatically.

Plug in, check your readings and understand your charging speed.
