If you're using an Android device and want to prevent your phone from sleeping while using maps, there are a few things you can do. On non-rooted devices, the app needs to request that the screen stays on. This is because the screen is a major source of battery drain, so mobile apps need to request a wake lock from the Android framework. This informs the system that something important to the user is happening, such as navigation. In the case of Google Maps, you can keep the phone awake by selecting Start Driving from the menu in the upper left corner of the app, even if you're not using turn-by-turn navigation.

What You'll Learn
Override the sleep setting in the app's menu
To keep your Android device awake while using maps, you can override the sleep setting in the apps menu. Here's how to do it:
Firstly, locate the app you want to keep awake on your home screen or launcher. Typically, this is done by long-pressing the app icon. This will display a menu with various options. From this menu, you can choose to keep the app active in the background, preventing it from sleeping.
On some devices, like Samsung, you may need to access the battery optimization settings. Go to Settings > Device Maintenance > Battery. Here, you'll find a list of apps that are allowed to run in the background without restrictions. You can add your maps app to this list by toggling it to "not optimized". This will prevent the device from forcing the app to sleep to save battery.
Another method is to use a wake lock, which informs the system that something important is happening, such as navigation. However, this method may not be available for all apps and may require the developer's implementation. Additionally, WiFi locks can be used on Android Nougat devices and below to keep the WLAN radio awake, but they won't work on newer versions of Android.
It's important to note that keeping apps awake in the background can drain your battery, so it's a good idea to manage these settings wisely and only enable them for specific apps when necessary.
By following these steps, you should be able to override the sleep setting and keep your Android device awake while using maps.

Allow location permissions
To allow location permissions on your Android device, follow these steps:
- Open your device's Settings.
- Tap on "Location". This option may be under "Security & Location" or "Privacy and Security", depending on your device model and Android version.
- Find "App location permissions" or "Site permissions".
- Locate the app you want to grant location access to, such as Google Maps.
- Tap on the app to adjust its location permissions.
- You will see several options, including "Allowed all the time", "Allowed only while in use", "Ask every time", and "Not allowed". Select the option that suits your preference.
- If you choose "Allowed all the time" or "Allowed only while in use", the app will be able to access your location when needed.
- Additionally, you can enable "Use precise location" for a more accurate position, or leave this option disabled.
It's important to note that while allowing location permissions can be convenient for certain apps, it may also raise privacy concerns. Be sure to review and adjust the location settings for each app on your device, granting access only when necessary.

Allow storage permissions
When you open a tool that requires access to your location, storage, or camera, the Android operating system will issue a pop-up asking if you want to ""Allow" or "Deny". If you select "Allow", you will be shown a dialog where you can choose to allow permissions all the time, only when the app is in use, or only if you allow it each time. If you select "Deny", you will continue to receive permission requests every time you open the app.
To allow storage permissions for a specific app, open the Settings app and tap "Apps & notifications". Find and select the app you want to check permissions for and tap "Permissions". You can now see all the app's permissions and change specific permissions by tapping on them. For storage permissions, you can allow the app to access your files, which will let it read and write to your internal or external storage. This means that a music app can save downloaded songs to your SD card, or a social networking app can save your friends' photos to your phone. However, a malicious app can secretly read, change, and delete any of your saved documents, music, photos, and other files, so make sure to assess Android apps for safety before installing them.

Request a 'wakelock' to keep the screen on
To keep the screen on while using maps on an Android device, the app needs to request a wakelock from the Android framework. A wakelock informs the system that something important to the user is happening, such as navigation, and prevents the device from sleeping.
The Screen Wake Lock API should be used to keep the device awake and prevent the screen from dimming or locking. To request a wakelock, the navigator.wakeLock.request() method is called, which returns a WakeLockSentinel object. The desired type of wakelock, currently limited to 'screen', is passed as a parameter. The request may be rejected for various reasons, including low battery or system settings, so it is good practice to store a reference to the sentinel object to allow the application to control its release.
Let wakeLock = null;
Try {
WakeLock = await navigator.wakeLock.request("screen");
StatusElem.textContent = "Wake Lock is active!";
} catch (err) {
StatusElem.textContent = `${err.name}, ${err.message}`;
}
The UI should be updated to reflect whether the wakelock is active or released. The wakelock can be released manually or automatically after a certain period of time.

Use an app that has a 'keep screen on' setting
When it comes to keeping your Android device from sleeping while using maps, one approach is to utilise an application that incorporates a "keep screen on" setting. This setting can be particularly useful when you need uninterrupted access to navigation or mapping services. Here are some insights and instructions to help you make use of this feature effectively:
On non-rooted Android devices, the ability to keep the screen awake is typically managed by individual applications. This means that the app developer must specifically include a "keep screen on" request in their application. When an app makes this request, it informs the Android framework that the user is engaged in a critical activity, such as navigation, and the device responds by preventing the screen from turning off.
To utilise this feature, look for mapping or navigation apps that offer a "keep screen on" setting. This setting is sometimes referred to as a wake lock or screen timeout disable. When enabled, this setting ensures that your device won't enter sleep mode while you're actively using the app, preventing the screen from timing out.
It's important to note that not all map-like apps may have this feature, and it's up to the developer to include it. Additionally, from an Android system perspective, there isn't a "keep screen on" setting tailored for individual applications. The system-wide option is to disable screen timeout entirely, which would apply to all apps.
When using a mapping app with the "keep screen on" setting, be mindful of your device's battery life. Keeping the screen active is a significant drain on battery power, so ensure your device is adequately charged or connected to a power source if you anticipate extended usage.
By using a mapping application with the "keep screen on" feature enabled, you can ensure uninterrupted access to navigation and location services without worrying about your Android device falling asleep mid-journey. Remember to consider your battery usage and adjust your settings accordingly for optimal performance.
