Why Is Turning Off Samsung Galaxy S23 Different?

The Galaxy S23 series continues Samsung‘s design philosophy of prioritizing Bixby access through the Side key. This decision reflects Samsung‘s commitment to building its voice assistant ecosystem, but it comes with a learning curve for new users.

Design Philosophy Shifts:

Samsung‘s approach represents a fundamental shift in smartphone design thinking:

1. Traditional Design (Pre-2019): Power buttons primarily controlled device power, with clear separation of functions
2. Transition Period (2019-2021): Consolidation of buttons with mixed user feedback
3. Current Approach (2021-Present): AI-assistant first, with power functions secondary

The dedicated Bixby button from older models has been eliminated, with its functionality now integrated into what traditionally was just a power button. This consolidation of buttons makes for a cleaner design but requires users to learn new methods for basic functions like powering off the device.

Industry Comparison:

Let‘s see how Samsung‘s approach compares to other major manufacturers:

Samsung justifies this design choice by pointing to research showing that modern smartphone users rarely turn off their devices completely, instead preferring to put them in sleep mode with a quick press of the Side key. Internal Samsung data suggests the average user only performs a complete shutdown approximately once every 2-3 weeks.
