Battery Calibration

I have a 4s with iso 9.3.5

I let the phone power off by itself when it got to 10%

Then i connected the charger, and turned the phone off so it can charge without interruption,

How will i know when the charge is 100% ? Because the screen displayed a battery with red in it, now its gone off.

There's no such thing as optimizing Apple's Lithium-ion batteries. Just turn it on.
