Earlier this week, another forum member also disclosed information that the models will use new ultra-low-power chips enabling the volume, power, and new 'Action' buttons to still function when the device runs out of power or is powered off.

Some iPhone users immediately expressed concerns about how the new capacitive buttons will function when they use cases or wear gloves. Addressing this concern, today's leak reveals that will introduce a new switch in the Settings app, allowing users to adjust the sensitivity of the buttons to suit these different usage scenarios.
It's known that iPhone case manufacturers often receive design details about upcoming models. Therefore, we are likely to soon verify today's information through leaked case images for the upcoming models.
According to previous reports, the new solid-state buttons are expected to be exclusive to the iPhone 15 Pro models, while the standard iPhone 15 models will continue to have physical buttons like those on the iPhone 14 series. The iPhone 15 Pro will also feature a new Action button, customizable to replace the silent switch, and come with a single volume button. Let's wait and see!
