How long does battery calibration take?
Last week I replaced my iPhone 8 Plus battery with an iFixit replacement. I followed the recommended steps for calibrating it, and kept cycling the battery full to empty and back when using the phone for the next couple of days, but it consistently shuts off at around 45-50% battery. It does last longer than the old exhausted Apple battery did, so it seems the capacity is fine, it’s just the calibration that’s off. Is this something that will fix itself with usage? Thanks.
Is dit een goede vraag?
