The iPhone 15 and iPhone 15 Pro series have previously announced the new appearance and new features, but in fact there are still many hidden features that have not been disclosed in the press conference. Recently, foreign media discovered in the iOS 17 RC version that the iPhone 15 may add new charging features that can avoid charging to 100% to extend battery life.

New method makes up for the shortcomings of “optimized battery charging”

9To5Mac reported that in the iOS 17 RC version, a new feature was found to be added to the code, allowing users to limit the maximum charging capacity of the iPhone. When the user turns on this function, the iPhone will notify the user that the battery will be charged to xx% (such as 97%), and prompt the iPhone to estimate the time it will take to complete charging.

Studies have shown that charging lithium batteries for a long time following charging to 100% will accelerate battery aging. Apple has also launched “Optimized Battery Charging” to reduce the time the iPhone is fully charged to protect the battery. However, “optimized battery charging” requires users to have a relatively stable charging habit before the effect will be significant. Therefore, the new feature can make up for the shortcomings of “optimized battery charging”.

iOS 17 will be available with the launch of iPhone 15, and the official version will be launched on September 18. Although this new feature was found in the code of iOS 17, 9To5Mac analysis predicts that this feature may not be available on all iPhones that can be updated to iPhone 17, or it may only be supported by the iPhone 15 series with USC-C.

Is there an undercurrent of price speculation for iPhone 15?The recycling price of old generation products rises instead of falling, and another domestic brand has greater demand

Earlier, it was reported that the iPhone 14 series’ battery health dropped by 10~15% following less than a year of use. This situation has occurred to many users around the world. Perhaps Apple hopes to use this new feature to avoid This happens once more with the iPhone 15 series.
