Calibration - Measuring total capacity

This screen helps maximize battery capacity and measure its aging. It can also handle multiple batteries and compare them easily.

How to measure total capacity (mAh):

• Run a 50% or more uninterrupted charge starting as low as possible.
  WARNING: Check this web site for battery aging.

• The phone needs to be on and the app recording battery history.

• Start charging as low as possible for better results.
• Increase accuracy by running larger charge cycle (best is 0% to 100%).

Update current/in-use mAh:

• When the measured/estimated mAh is precise enough

• The "Update mAh" opens a dialog where you can adjust the capacity to use from now on.

How accurate is the estimated/calculated mAh?

Reset Aging / Update mV range Reference:

• When the aging is incorrect due to incorrect mV reported (by Android).

• The "Update references" updates the mV range and resets the aging %

How to change battery: 

• Turn off the phone.

• Change the battery physically.

• Start the phone.

• Change the battery in the calibration screen of the app.

Important notes:

• The app supports 2 types: phones that report measured mA and phones that report estimated mA.

• On main and calibration screens, "Estimated:" will replace "Measured:" or "Actual:"

• When estimated it is important to set the AC charger capacity to control the charge process.

   

• Do not change history logging rate, it will prevent calculating mAh. 

• Run continuous uninterupted charge cycle.
