Conclusion

Preventing screen timeout is essential for many modern workflows and use cases. Whether you choose web-based solutions, built-in system settings, or third-party software, the key is selecting the right method for your specific device and needs.

For most users, Keep Screen On offers the most convenient and universal approach, working across all modern devices and browsers without requiring installations or permanent system changes. It's particularly valuable for temporary needs like presentations, video calls, or reading sessions.

For permanent setups or enterprise environments, system-level configurations provide more robust control. However, the flexibility and ease of use of web-based wake lock solutions make them ideal for most everyday scenarios.

Remember to balance functionality with battery life and security considerations. Use "always-on" settings judiciously and restore normal power management when extended display time is no longer needed. Tools like Keep Screen On make this balance easier by providing temporary wake lock functionality that can be easily toggled on and off as needed.
