Apple's explanation of iPhone battery decline?

Currently, Apple has not yet given any feedback on user feedback. However, Apple has mentioned the issue of degraded battery performance on its support website.

According to Apple, "Conventional batteries are designed to retain 80% of their original capacity after 500 full charge cycles under normal operation. Batteries are covered by a one-year warranty against defects. If the warranty expires, Apple provides a battery replacement service for a fee."

A smartphone charging cycle is the process of using up and fully charging the battery. According to data published by Apple, if users perform 1 charging cycle for iPhone 14 every day, after 250 days, the battery capacity on the product will be reduced by 10%.

iPhone 14 has been on the market since September 2022, so far it has been about a year. If the average daily charge cycle is performed, then so far the battery capacity is reduced by 10 to 15% which is acceptable compared to what Apple has stated.

In the process of users using smartphones, there are many factors such as high temperature, frequent use for a long time continuously . also contribute to shortening the life of the battery.

In addition, currently lithium-ion batteries used on iPhone 14 and other types of mobile devices also have a reduced lifespan over time.

Therefore, it is normal for the iPhone 14 battery to be reduced to 90% of its original capacity after nearly a year of use.
