The amount of misinformation always excels with a new release. Lithium ion batteries do not have a memory. The batteries cannot be calibrated. The battery has no clue if it is full, 1/3, or whatever. So all these people running your battery down are actually putting stress on the battery. The only element that can be calibrated is the meter itself. Like the phone thinking it is at 95% and maybe it is really 93%. Charge your phone as often as possible. This keeps cycle counts down and enough with "calibrating".
