How Can an iPhone's Battery Health Go Down from Aging and Overuse

As your iPhone ages, its battery health can decline due to natural wear and tear. Over time, the battery's ability to hold a charge can decrease.

One of the main reasons for this decline is the chemical degradation of the battery's internal components. This process can start as early as the first year of use.

Aging also causes the battery's internal connections to break down, leading to a decrease in overall battery health. This can result in reduced battery life and performance.

According to Apple, an iPhone's battery is designed to retain up to 80% of its original capacity after 500 complete charge cycles.
