The Overly Sensitive Screen
Modern iPhones utilize internal accelerometers and gyroscopes to power a feature called “Raise to Wake.” The moment the phone detects that it is being lifted from a horizontal position into a vertical, viewing angle, it automatically turns on the OLED display and prepares the Face ID scanners. While this is incredibly convenient when pulling the phone out of your pocket to check a notification, it is highly sensitive. If you frequently carry your phone in your hand while walking, or if you gently slide it across your desk, the screen will constantly flash on and off. This not only creates a distracting visual strobe effect in a dark room but also significantly drains your battery over the course of a day. If you prefer to have absolute control over when your screen illuminates, you should disable this sensor.
How to Turn Off Raise to Wake
You can disable the physical motion trigger within the main display settings.
- Open the Settings app on your iPhone.
- Scroll down the main list and tap on Display & Brightness.
- Scroll down to the middle of the page.
- Locate the toggle switch labeled Raise to Wake.
- Tap the switch to turn it Off (the green background will disappear).
The Classic Behavior Restored
The change takes effect instantly. From now on, you can pick up your iPhone, wave it around, or run with it in your hand, and the screen will remain completely pitch black. To wake the phone up, you must now explicitly perform a physical action: either tapping the glass screen once with your finger (if “Tap to Wake” is enabled in accessibility settings) or pressing the physical Side Button on the right edge of the device. This guarantees the phone only turns on when you actually intend to use it.
