According to wccftech, many users have previously complained that the battery health of the iPhone 14 series dropped rapidly after several months of use. The latest news claims that the iPhone 15 series may have the same problem.

In contrast,Many Chinese mobile phone brands, such as OPPO, vivo, etc., use batteries with up to 800 charging cycles, OnePlus uses a more advanced self-healing battery that supports 1,600 charging cycles.
wccftech believes that during the global economic recession, Apple must make difficult choices to maximize profits while maintaining product prices, and this can only be achieved by cutting costs somewhere.
In August this year,According to 9to5Mac, less than a year after the iPhone 14 Pro was officially launched, more and more users have shared screenshots of their deteriorating battery capacity on social platforms in recent months.
According to rough statistics from 9to5Mac, the battery capacity degradation of these users ranges from 14% to 9%, with the lowest being only 86%.
Apple started adding a "Battery Health" feature to iPhone in iOS 11.3 in March 2018. At the time, Apple confirmed that it had been quietly limiting iPhone performance in an effort to slow battery degradation over time.
According to Apple's official website, as the battery chemically ages, the battery's capacity decreases, which may result in reduced use time between charges.
When running under normal conditions, an ordinary battery can retain 80% of its original capacity after 500 complete charging cycles.The one-year warranty includes coverage for defective batteries. If the warranty period is exceeded, Apple will provide battery services for a fee. As a battery's health declines, so does its ability to deliver peak performance.
For users, as the iPhone battery ages, you need to charge your iPhone more frequently. The more the iPhone is charged, the faster the battery ages, forming a vicious cycle. Although it is normal for iPhone batteries to age, the number has dropped significantly faster this year than in previous years.
