About battery health
I have an iphone 11 with a battery health of 98% then after a month of using it, the battery health went back to 100%? May i know the reason why? Thanks.
Battery health is an estimate of the health of your device's battery. It's possible that Apple changed the algorithm that calculates health and it's possible that your usage pattern altered the health. It's really an unknown, but also not important. Your battery will degrade over time. Provided it is 80 percent or higher, there is nothing to worry about.
