Special touch button on iPhone 15 Pro

The iPhone 15 Pro and Pro Max may use an ultra-low power processor, allowing the touch buttons to still work even when the phone is turned off or out of battery.

Rumors come from a Macrumors forum member, who says the new processor will replace Apple's current ultra-low power mode, allowing iPhones to be located via Find My after being turned off or drained for 24 hours, and enabling Apple Pay Express Mode for up to 5 hours.

The new chip takes over existing Bluetooth LE/Ultra Wideband functionality, in addition to powering solid-state capacitive touch buttons, including an “action” button that replaces the mute switch, when the phone is on, off, or running out of battery.

The processor will “immediately sense button presses and holds, and even detect 3D Touch-style pressure on the new volume up/down buttons, action buttons, and power button, while the phone is off,” the source revealed.

The feature is currently being tested, the person said. If the iPhone is off, the Taptic Engine feedback is also disabled, but it still appears in situations where the battery is dead. However, “it is uncertain whether it will make it to production.”

The source confirmed that Apple “insiders” saw two new types of volume buttons being tested, including a version that increases/decreases the volume depending on the force of pressing and a version that adjusts by swiping up and down.

They don't know what method will be used for the official release, but these features are software-enabled, so it's possible that users will be allowed to customize them as well.

The anonymous source claims the information comes from Apple's development team, so they don't know much about the design of the new iPhone, except for the physical details that would require building the software to make it work.

According to previous rumors, the capacitive touch buttons are exclusive to the iPhone 15 Pro, while the standard line retains the traditional mechanical buttons as on the iPhone 14.

On MacRumors, this user shared accurate information about Dynamic Island last year, before the iPhone 14 Pro was officially launched.

According to Gizmodo, if this information is correct, Apple will continue to widen the gap between the Pro line and the basic line. Thanks to limiting physical details, the device is also more durable than the previous version, something Apple did with the Apple Watch Ultra.

Not long ago, ShrimpApplePro claimed that the iPhone 15 Pro and iPhone 15 Pro Max would have titanium frames instead of steel like the previous generation Pro lines. This rumor also coincides with the prediction of Jeff Pu, a technology market analyst at Hong Kong investment fund Haitong International Securities.
