Since years ago, Apple’s official support website about the performance and lifespan of iPhone batteries has claimed that “normal batteries” can retain up to 80% of their initial capacity after 500 charging cycles. A full discharge from 100% to 0% and a subsequent recharge back to 100% is referred to as a charging cycle.

Occasionally, rival companies promote a noticeably longer battery life. For instance, while using 100-watt fast charging, the OnePlus 11 is technically capable of 1600 charging cycles. With Apple’s recent confirmation to 9to5Mac that the iPhone 15 should reach 1000 charging cycles before the battery capacity decreases to 80%, the tech giant is now readjusting its own statistics. The advancements Apple has made to the iPhone’s batteries and charging procedures over the last few years are the reason for this noticeably extended lifespan.

Apple claims that only the iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max are eligible for this extended battery life. The manufacturer does stress that, should the need arise, battery life data for earlier models is presently being examined and adjusted. Nevertheless, these numbers only relate to “real-world” scenarios in which Apple conducts internal testing on its iPhone batteries. In reality, a battery’s actual service life is mostly determined by its usage, including how frequently it is recharged over 80% or below 20%, as well as the temperatures it is subjected to.
