Preventing Android Devices from Entering Sleep Mode During Gameplay in Unity

Ensuring that an Android device remains active during gameplay is crucial to providing an uninterrupted gaming experience. Here are the steps you can take to prevent an Android device from entering sleep mode while using Unity:

1. Using Unity’s Built-in Methods

Unity provides a straightforward way to prevent a device from sleeping by setting the Screen.sleepTimeout property. You can set this property within your Unity script as follows:

Start playing and winning!

using UnityEngine;

public class PreventSleepMode : MonoBehaviour
{
    void Start()
    {
        // Prevent screen from sleeping
        Screen.sleepTimeout = SleepTimeout.NeverSleep;
    }

    void OnApplicationQuit()
    {
        // Restore the default timeout when the application quits
        Screen.sleepTimeout = SleepTimeout.SystemSetting;
    }
}

This snippet sets the sleep timeout to SleepTimeout.NeverSleep, which prevents the device from sleeping, and restores it to the system default upon application exit.

2. Configuring Android Settings

For additional control, especially during development, you can use Android’s developer options. Enable the ‘Stay Awake’ setting under Developer Options, which keeps the screen active while charging.

3. Handling Battery Implications

Keep in mind that preventing sleep mode will affect battery consumption. Consider providing users with an option to toggle this setting, thereby enhancing user control while balancing device battery usage.

By following these steps, you can effectively prevent an Android device from entering sleep mode during gameplay in Unity, ensuring a smooth and uninterrupted gaming experience.
