Why is the Smartphone Power Button Always on the Right Side? Uncover the Design Secrets!

• The power button's right-side placement caters to the majority (90%) of right-handed users, allowing natural thumb access for one-hand operation.
• Integration of fingerprint sensors into the right-side power button enables instant unlocking, enhancing user convenience and speed.
• From an engineering standpoint, the right side offers optimal space, avoiding conflicts with internal components like SIM trays or volume buttons often found on the left.
• With increasing screen sizes (6.7 inches and above), placing the power button on the right makes it easily accessible by the thumb, unlike top-mounted buttons.
• Future trends suggest a move towards buttonless phones, utilizing in-display fingerprint, face unlock, or touch/pressure sensors.
