Frequently Asked Questions
Does Screen Timeout affect phone performance?
No. Screen Timeout only controls how long the display stays ON. It does not slow down your phone or apps.
What happens if I set Screen Timeout to “Never”?
The screen will stay ON until you lock it manually. This drains battery quickly and reduces privacy, so it is not recommended for daily use.
Is shorter Screen Timeout always better?
Short timeout saves more battery, but very short durations can be annoying while reading. Choose a balance that suits your usage.
