Apple Increases iPhone 15's Advertised Battery Lifespan
Apple today announced that it retested the batteries in all iPhone 15 models and determined that they are able to meet a higher bar.

In a support document updated today, Apple says the batteries in the iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max are designed to retain 80% of their original capacity at 1,000 complete charge cycles under ideal conditions, compared to the 500 charge cycles it advertises for all older iPhone models.
Apple told MacRumors that its latest testing for iPhone 15 models involved charging and discharging the battery 1,000 times under specific conditions, but it did not provide any exact details about the process. Apple added that it has continually made improvements to iPhone battery components and its power management system.
This revelation means that it could take longer for the maximum battery capacity of iPhone 15 models to decline to 80% compared to previous iPhone models. However, Apple said it is "investigating" the battery lifespans of older iPhone models, so a comparison based on the latest testing parameters remains to be seen.
In its support document, Apple says the battery lifespan of any iPhone model ultimately depends on how the device is regularly used and charged.
To view an iPhone's battery capacity, open the Settings app and tap Battery → Battery Health & Charging. On iPhone 15 models updated to the latest iOS 17.4 beta, the menu is now simply called Battery Health and shows more info at a glance.
