Apple has revamped its battery lifespan estimations for the iPhone 15 and iPhone 15 Pro models, announcing that their batteries can maintain 80% of their initial capacity after 1,000 complete charge cycles under optimal conditions, nearly double the previous estimation of 500 cycles for older iPhone models.
Improved components and enhanced power management systems within the iPhone 15 models contribute to this extended lifespan. Despite this update, the battery lifespan of pre-2023 iPhone models remains at 500 cycles.
To assist users in managing their device’s battery health, Apple introduced new battery health controls with the launch of iOS 17, including a feature limiting charging to 80%, which reduces stress during charging and potentially prolongs battery lifespan.
With the recent iOS 17.4 update, Apple provides a clearer interface for viewing battery health information and charging optimization settings directly from the Battery section in Settings (Battery > Battery Health).
Users experiencing battery issues with newer iPhone models, such as rapid battery health deterioration, have expressed concerns on discussion platforms, highlighting the importance of proper maintenance and care to ensure optimal battery performance.
Overall, Apple’s decision to extend the battery lifespan of the iPhone 15 series demonstrates the company’s commitment to improving user experience and sustainability efforts. However, the impact of this update on older iPhone models remains uncertain, pending further investigation by Apple.
