New Tests Show iPhone 15 Batteries Could Last Significantly Longer Than Older Models
• Apple retested iPhone 15 batteries and found they can retain 80% capacity after 1,000 charge cycles, higher than the 500 cycles advertised for older models
• This means iPhone 15 batteries could last longer before declining to 80% max capacity compared to previous iPhones
• Actual battery lifespan still depends on real-world usage and charging habits
• To check battery health, open Settings app and go to Battery → Battery Health & Charging (Battery Health in iOS 17.4)
• Apple is still investigating older iPhone models to retest batteries against the latest parameters
