3D Touch revolutionized iPhone interaction with pressure-sensitive controls, exclusive to iPhone 6s and 6s Plus (and future models). It enables actions like Peek and Pop based on press intensity, detected by the device's hardware.
Pressing habits vary, so what feels right for one user might not for another. Apple thoughtfully provides customization options in iOS settings, letting you fine-tune sensitivity to match your touch style perfectly.
Access these settings quickly: Open Settings > General > Accessibility > 3D Touch.


Here, toggle 3D Touch off entirely if it interferes with daily use—no more unintended pressure activations.
For sensitivity tweaks, drag the slider: Left for Light (less pressure needed), right for Firm (harder presses required). Default is medium.


From my hands-on experience with the iPhone 6s since launch, Light sensitivity suits me best—it eliminated the frustration of overly firm presses out of the box.
Pro Tip: Test settings using Apple's built-in 3D Touch Sensitivity Test. Press the sample firmly to practice Peek and Pop.
For broader touch adjustments, explore Accessibility options like Touch Accommodations—ideal for accessibility needs.
