"Battery life test between iPhone 12 and iPhone 14: I want to know how the iPhone 15's battery life is longer than the iPhone 12. According to my knowledge and PC Magazine, the iPhone 15's battery life is about 3 hours and 9 minutes longer than the iPhone 12. I am not sure if this is true, but let me know your answers."

How iPhone 15 Has a Longer Charge Span:

When the battery chanrge reaches 80%, it stops charging. When it gets to 75%, it begins changing once more. This put less strain on the battery.
