I haven’t plugged my iPhone to Unity so I don’t understand why on every frame, I get:

Input.acceleration.x = -0.02729797

How can I force it to be equal to zero when there is no input?

The acceleration sensor (like most others) is very sensitive and its output is practially never zero, there is always a little bit of noise.
