Hab grad ne Antwort von iMazing bekommen: „Battery health in iMazing is calculated as Design Max Charge/Effective Max Charge. Both values are received from the device report, and they can be different depending on the battery charge level, temperature and battery state in general.Also, iOS device will always show the battery health a bit higher than it is.“

Hab dann gefragt, ob die wissen, wie Apple den Wert „berechnet“. Vermutlich wird aber der genommen, der grad am höchsten ist.
