I don’t know how accurate this shortcut method is. I understand that it’s just reading a log file, but it is so far off from the estimates Apple is reporting in Settings, it’s hard to believe. I have four phones in my house, and each one was anywhere between 5 to 8% off.

My work iPhone 11 was the worst. The shortcut showed 91%, settings shows 98%. My new iPhone 15PM is showing 95% while settings is showing 100. I think I’ll just choose to live in blissful ignorance and use the Apple battery health displayed in settings.
