Recent leaks indicate that the volume control button on upcoming iPhone (iPhone 15 Pro) and (iPhone 15 Pro Max) could be a one-touch button that responds to vibration when pressed instead of the two separate buttons on the current iPhone button.
YouTuber ZoneOfTech said on his Twitter account that Apple usually uses pins to house each button on the body of the phone, but the recently leaked iPhone 15 Pro drawing only shows the pins in the single hole where the button is located. generally settled. In contrast, the drawing (iPhone 15) shows two separate holes for a total of four pins.
ZoneOfTech has built a mockup of the new phone based on leaked graphics and says it's safe to say the phone will have a unified volume control button instead of two separate buttons. Also, the mute button is also supposed to become a touch button instead of the current one.
Almost 100% sure that the iPhone 15 Pro will LONG Unified Volume button, rather than 2 separate ones.

While making our iPhone 15 Pro Concept, we’ve found that Apple uses 2 pins on each of the 2 volume buttons. The iPhone 15 Pro CAD only shows 2 pins on a longer volume button. pic.twitter.com/KzkpS9fYBB
The touch button technology helps protect the device from dust and water, as the buttons in this case do not require a pressure mechanism, but rather other devices inside the phone. Reports indicate that Apple intends to add two additional actuators to the haptic control system in new buttons on upcoming Apple phones to provide vibration feedback. It's unclear how the new touch buttons work through the protective cover.
The first generation iPhone must have relied on a long button to control the volume. Apple continued to use this design until the launch of the mobile phone (iPhone 4), replacing the single button with two circular buttons, then switching from (iPhone 6) to (iPhone 14) with two rectangular buttons.
It should be noted that the new changes only affect (iPhone 15 Pro) and (Pro Max), while (iPhone 15) retains the same buttons as the current device.
