Recently, there has been an increasing amount of speculation about the new generation of the iPhone 15 series, and it is no surprise that the series will continue to launch four models, including the iPhone 15, iPhone 15 Plus, iPhone 15 Pro, and iPhone 15 Pro Max. The latter two will bring upgrades in many aspects and have received a high degree of attention. Not long ago, a well-known insider has further released more configuration details of the phone.

A source on the MacRumors forum said that Apple's iPhone 15 Pro and Pro Max will use low-power microprocessors to ensure the use of certain features even when the phone is turned off, and will provide support for new capacitive solid-state buttons (tactile feedback buttons). This source accurately disclosed the details of "Dynamic Island" before the official release of the iPhone 14 Pro last year, so at present, we have reason to believe that this is reliable disclosure.

The anonymous source said that Apple will replace the ultra-low power mode of the current SoC (AX) chip with the new microprocessor, allowing the iPhone to be located within 24 hours after it is turned off or the battery is depleted via Find My, as well as Bluetooth/UWB and Apple Pay quick payment mode and other functions.  It is alleged that in addition to powering solid-state buttons, it will take over all of these existing functions:

When the phone is on:

-Capacitive volume buttons, power button and multi-purpose operation buttons.

When the phone is off:

-Capacitive volume, power and operation buttons.

-Drive NFC, LE Bluetooth, LE-UWB chips, etc.

(may support Taptic Engine feedback)

When the battery is depleted:

-Capacitive volume, power and operation buttons.

- Apple Pay Express quick payment

-Drive NFC, LE Bluetooth, LE-UWB chips, etc.

The source also said that Apple is currently testing some features, such as Taptic Engine feedback. "Whether this little feature will make it to the final release is very uncertain, but it's currently being tested," he added.

It is said that "insiders" have seen two versions of the unified volume button function in testing, with one version capable of quickly raising/lowering the volume based on how much pressure you press, while the other version can adjust the volume by sliding up and down with a finger, but it is unclear which method Apple will ultimately adopt. Of course, this function is implemented through software, and the volume button integrated with 3D Touch has been determined. Apple may directly provide two solutions for users to choose freely.
