FAQ
Is keeping the screen on safe?
Yes, when used responsibly. The main impact is battery and heat, not security.
Do browser-based tools install anything?
No. They run in your browser and can be stopped instantly.
Why does my screen still turn off sometimes?
Battery saver policies, background tab limits, and OS-level restrictions can override wake behavior.
Final recommendation
Start simple: use browser wake lock for temporary sessions. Move to system or automation methods only if you need persistent, repeatable behavior.
