New charging mode will help extend iPhone 15 battery life

Although iOS has already provided the "Optimized Battery Charging" function, its effect on slowing down battery aging may not be that significant. but. Recently, 9to5mac discovered a new limited charging option in the code of iOS 17 RC, which should help extend iPhone battery life.

This feature is not yet available in iPhone 14 and other older iPhones. It's unclear whether this feature is reserved for the iPhone 15 using USB-C, or whether it will be available as soon as the iPhone 15 series launches. However, once the official version of iOS 17 is launched, this feature is expected to appear in the "Battery" settings menu.

Here’s how it’s expected to work:

• iPhone users will be able to set a charging limit for their battery. Suppose you set this limit to X%, then the next time you charge the phone, the phone will "only be charged to about X%." You'll receive a notification on the lock screen.
• If you do not enable this feature, the iPhone will "charge to its full capacity."
• You should also be able to find the last time your iPhone was charged to the default limit in the "Battery" settings menu.

It is worth noting that Apple is not the first company to launch this type of feature. Its rival in the Android market, Samsung, has a similar "battery saver" option that allows Galaxy phone owners to limit charging to 85%. Frequent charging of lithium-ion batteries often accelerates battery aging, and limiting it to a percentage will help extend battery life.
