Rumors surrounding the iPhone 15 Pro and Pro Max's capacitive solid-state buttons have been circulating for several months now, and a recent post on the MacRumors forums has unveiled further information regarding their functionality.
According to sources, Apple intends to introduce a unified volume button and a new programmable Action button to the iPhone 15 Pro series.
The latter is expected to incorporate the signature iPhone mute switch feature, along with several other programmable functions, including toggling the orientation lock, flashlight, low power mode, and more.
What's more, the iPhone 15 Pro's solid-state buttons are set to feature customizable sensitivity, thanks to a low-energy microprocessor dedicated to the capacitive buttons.
This innovative chip will operate even when the phone's battery is depleted, detecting user presses and holding gestures while also delivering Taptic Engine feedback.
Users will be able to adjust the sensitivity of the buttons via the Settings menu and can even use them with phone cases or gloves.
In addition to powering the iPhone 15 Pro's solid-state buttons, the new low-energy chip will also support the NFC, Bluetooth LE, and UW chips even when the device is powered off or the phone's battery is entirely drained.
