With the help of this application, you can check everything that is happening with the battery. Charge level, fast charging power and battery temperature are displayed in graphs. Just press the Start button and after a while the graphs will start to appear.

App features:

- battery charge graphs (charge level, charge power and battery temperature). Data is updated every 1 minute.
- battery discharge graphs. Data is updated every 1 hour
- sound notification of full charge (100% level + until we receive Full Charge status from the system)
- current battery status (power, voltage, current, temperature)
- forecast of time to full charge (calculated based on the previous successful charge of at least 50 to 100%)
- forecast of time to full discharge
- the app runs in the background and consumes very little power.

* attention, the application measures all electrical parameters exactly on the battery, not on the output of the charger! Therefore, all parameters will differ from those shown by the USB tester.
