Did you ever before really felt, that a person Charger/USB wire set fees your device truly fast as well as the various other not? Now, you can verify this with Ampere. Measure the asking for and also releasing present of your battery. The application works on Android 4.0.3+ tools. Not every device is supported because there are gadgets which does not have a proper dimension chip (or the interface) as well as they can not be assisted at all. Please check out the listing of not supported phones at the end of the description.
The application is not indicated to be mA accurate. It is just good for review which Charger/USB cord combination is working the very best for you on the exact same gadget. Start the app and also wait ca. 10 secs (“gauging” is on the monitor). Then time, the charging or discharging present will certainly be revealed.
- Alerts on device
- Alerts on Android Wear
The current depends on many things
- The battery charger (USB/AC/Wireless)
- The USB cable
- The phone kind
- Current tasks running
- Present brightness
- WiFi state
- GPS state
Please don’t use the readings on this app as concrete science. However, the readings are good enough to relatively measure how various chargers and USB cables fair on the same device.
Unfortunately some Samsung devices don’t give correct (measured) values (e.g.: S5), just the maximum possible charging current with the actual USB cable/charger configuration. This is a firmware problem.
About Notification and Background Measurement
- The measurement works in the background only if you switch on the notification in the settings.
- You can hide the notification icon by setting the notification priority to minimum.
The app measures the charging/discharging current of the battery. If your phone is not connected to a charger, you see the discharging current which is negative. If you connect a charger then the current what the charger gives will be used to supply your phone and the remaining power will be charged into the battery.
If your phone consumes 300 mA without a charger connected (-300mA on the display), then a 500 mA charger will charge your battery maximum with 200 mA current (200mA on display).
The displayed current is an average value from 50 measurements minus the 10 upper values and the 10 lower values. The displayed current can be shaky or unstable or even just zero which means, that the Android system provides such unstable values. Every company uses different battery types and other hardware making it difficult to get accurate results about your charger.

NOTE: If the measured value is always 0, please try to use the “Old measurement method” and/or the “Measurement interface” settings options (if available).
LiPo batteries don’t draw the maximum for the full time it takes to charge the phone. If your battery is charged almost full then the charging current will be much less as by lower battery levels.
