Apple Doubles iPhone 15 Battery Lifespan

According to a report by 9to5Mac, Apple has announced that the battery life of the iPhone 15 series surpasses expectations, maintaining 80% of its original capacity even after 1,000 complete charge cycles.

Previously, Apple had disclosed that the lifespan of an iPhone battery was designed to retain up to 80% of its original capacity after 500 full charge cycles. The iPhone 15 series has now doubled this performance benchmark, thanks to Apple’s continuous advancements in battery components and power management systems. After undergoing 1,000 charge and discharge cycles, the iPhone 15 models still boast 80% of their initial battery capacity. Apple has updated the battery health metrics for all iPhone 15 models, undoubtedly a boon for users of this series. This not only signifies a more durable device but also impacts the resale value of the iPhone series significantly, given the well-known effect of battery health on resale prices.

Contrary to what might be expected, the report mentions that Apple’s testing method involved merely charging and discharging the phones 1,000 times using standard procedures. This achievement in extended battery lifespan is not the result of Apple unlocking any software restrictions or introducing new features in iOS 17.4 Beta 4.

However, Apple has specified that this extended battery lifespan currently applies only to the iPhone 15 series. The battery lifespan of all previous models remains at the standard of retaining 80% capacity after 500 full charge cycles. Apple also mentioned that it is currently conducting battery lifespan tests on older iPhone models.
