Yes, it's true the calibration meter is also inaccurate, because even in laboratories in my university or anywhere, the meter is always faulty, what we call as zero error..
We can't get accurate readings, we can try to eliminate them by calibrating the instrument to minimize the systematic error..
Even in the USA using the most advanced technology in the world, they set up standards to which measurements are calibrated according to their standards, indeed their instruments also are not accurate, but more accurate relative to other instruments as they use the most sensitive and accurate measurements...
In conclusion, this are just phones, well smartphones, no matter how good is it, a small error in battery, for me I don't think it's going to effect our daily lives right?
With that said, if battery calibration cannot work, I guess it's best we let it go, and just assume it's a battery inaccuracy ....
