iPhone batteries

iPhone batteries use lithium-ion technology, which stores and releases electrical energy through chemical reactions. Over time, these reactions cause the battery’s capacity to decrease, leading to shorter usage between charges. Batteries have a finite number of charge cycles—full charge and discharge cycles—before their performance diminishes noticeably. Charging habits, temperature, and age also impact battery health. iPhones include software features to optimize charging and prolong battery lifespan, and when the battery’s capacity drops significantly, it can be replaced to restore performance. Proper care and mindful charging can extend the battery’s effective lifespan.
