Apple doubles the advertised battery lifespan of the iPhone 15 and iPhone 15 Pro

Apple's official support page on the performance and service life of iPhone batteries has stated for years that "normal batteries" have been developed in such a way that they still have up to 80% of their original capacity after 500 charging cycles. A charging cycle is defined as a complete discharge from 100 to 0% and a subsequent recharge back to 100%.

Competitors sometimes advertise a significantly longer battery life. For example, the OnePlus 11 officially achieves 1600 charging cycles despite 100-watt fast charging. Apple is now readjusting its own figures, as the technology giant recently confirmed to 9to5Mac that the iPhone 15 should reach 1000 charging cycles before the battery capacity drops to 80%. This significantly longer lifespan is the result of improvements that Apple has made to the batteries and charging processes of iPhones over the past few years.

According to Apple, this longer battery life applies exclusively to the iPhone 15, iPhone 15 Plus, iPhone 15 Pro and iPhone 15 Pro Max. However, the company emphasizes that the battery life of older models is currently being reviewed in order to adjust battery life information if necessary. In any case, these figures only apply to "real-world" conditions under which Apple tests its iPhone batteries internally. In practice, the actual service life of a battery depends heavily on usage, including how often the battery falls below 20% or recharged above 80% and what temperatures the battery is exposed to.
