Charge Ticker

See exactly how fast your phone is charging, or how fast it's draining, as it happens.

Charge Ticker shows the current going into or out of your battery, live, in milliamps and watts. Plug in a different charger or cable and watch the number change. Find out which charger is really fast, whether wireless is slower, or what's draining your battery.

• Live current, updated every second: green when charge is going in, orange when it's going out
• Watts, plus a smoother 1-minute average
• A graph of the last 5 minutes
• Voltage, temperature, charge left, estimated battery capacity, charge cycles and health
• Time until full, or how long the battery lasts at the current rate
• Running total since you plugged in or unplugged: how many mAh went in or out
• Optional live number in the status bar, so you can see it from any app
• Light and dark themes that follow your phone, with Material You colors
• No ads, no account, no tracking. Battery readings never leave your phone.

Works on Android 13 and newer. Most phones report charging current; a few don't, and the app tells you if yours is one of them. If charging shows as negative on your phone, turn on "Flip + and −" in Settings.
