Screen Timeout / Sleep Mode Setting auf OnePlus
The Sleep setting on OnePlus phones controls how long the display stays active after your last touch. Once the countdown ends, the screen goes dark and the phone enters standby to save battery. The display is one of the biggest power consumers in daily use, so a timeout of 30 seconds or one minute is usually enough for most people.
A very long timeout, such as several minutes, keeps the screen bright even when you are not looking at it. That adds up over a day and shortens battery life noticeably, especially with an always-bright panel and high refresh rate active.
You find this option under Open the Settings ➔ Tap on Display ➔ Tap on Sleep ➔ Set the duration until sleep. Pick a value that matches how you use the phone: shorter for battery savings, longer if you often read or watch content without touching the screen.
If you use a pattern, PIN, or fingerprint lock, a short Sleep timeout also means the screen locks sooner after you put the phone down. That is useful for privacy but can feel abrupt if set too aggressively, so test a middle value like one minute before going lower.
