Battery Health
My phone's battery health is 85% bt its still showing,"yours phone's battery health is degrading...." i wnt to know why is it showing such alert even at 85%?
iPhone X, iOS 15
Because your battery is getting close to needing to be replaced. I don't know at exactly what point the warning comes on exactly. My battery is at 86% and I don't see it.
Once your battery capacity drops below 80%, you should have it replaced.
