The iPhone 15 Pro may feature haptic solid-state volume and power buttons
 

The next-gen iPhone 15 Pro models may swap its physical volume and power buttons for solid state versions that use haptic feedback, analyst Min-Chi Kuo wrote in a tweet spotted by MacRumors. The design would be similar to the non-physical home button on the iPhone 7, which used a Taptic Engine to simulate a button press with vibrations. It could also resemble Mac trackpads, which don't move but simulate clicks using similar haptic technology.
