As we continue to rely on our smartphones for various tasks, battery life has become a major concern for many users. To address this issue, Google introduced a power-saving feature called Doze in Android 6.0 Marshmallow, which was later improved upon in Android 7.0 Nougat with the introduction of Deep Doze. In this article, we will delve into the world of Deep Doze, exploring what it is, how it works, and its benefits.
What is Deep Doze?
Deep Doze is an enhanced version of the Doze feature, which was designed to reduce battery consumption when a device is not in use. While Doze was a significant improvement over previous power-saving features, Deep Doze takes it to the next level by introducing new restrictions and limitations to minimize battery drain.
When a device is in Deep Doze mode, it enters a state of deep sleep, where most system services are suspended, and network connectivity is disabled. This means that the device will not receive notifications, emails, or other updates during this time. However, unlike Doze, which only kicks in when the device is stationary and not in use, Deep Doze can be triggered even when the device is in motion.
How Does Deep Doze Work?
Deep Doze works by using a combination of sensors and algorithms to detect when a device is not in use. When the device is stationary and the screen is off, the system will enter a state of light sleep, where some system services are suspended, but network connectivity remains active. However, if the device remains in this state for an extended period, it will enter Deep Doze mode.
In Deep Doze mode, the system will:
- Suspend most system services, including Wi-Fi and Bluetooth scanning
- Disable network connectivity, including mobile data and Wi-Fi
- Restrict app syncing and updates
- Limit CPU performance to reduce power consumption
The system will periodically wake up from Deep Doze mode to perform maintenance tasks, such as syncing data and checking for updates. However, these wake-ups are designed to be brief and infrequent, minimizing the impact on battery life.
Deep Doze Modes
There are two types of Deep Doze modes:
- Light Deep Doze: This mode is triggered when the device is stationary and the screen is off. In this mode, the system will suspend some system services, but network connectivity remains active.
- Deep Deep Doze: This mode is triggered when the device is in motion and the screen is off. In this mode, the system will suspend most system services, including network connectivity.
Benefits of Deep Doze
Deep Doze offers several benefits, including:
- Improved Battery Life: By suspending system services and disabling network connectivity, Deep Doze can significantly reduce battery consumption, resulting in longer battery life.
- Reduced Power Consumption: Deep Doze can help reduce power consumption by limiting CPU performance and disabling unnecessary system services.
- Enhanced Security: By restricting app syncing and updates, Deep Doze can help prevent malicious apps from running in the background and consuming battery power.
How to Enable Deep Doze
Deep Doze is enabled by default on devices running Android 7.0 Nougat and later. However, you can also enable it manually by following these steps:
- Go to Settings > Battery > Battery saver
- Toggle the switch to enable Battery saver
- Select the “Deep Doze” option
Note that Deep Doze may not be available on all devices, and some manufacturers may have customized the feature to work differently.
Customizing Deep Doze
While Deep Doze is enabled by default, you can customize it to suit your needs. For example, you can:
- Set a custom Deep Doze timeout: You can set a custom timeout for Deep Doze to kick in, ranging from 30 minutes to 2 hours.
- Exclude apps from Deep Doze: You can exclude certain apps from Deep Doze, allowing them to continue running in the background even when the device is in Deep Doze mode.
To customize Deep Doze, go to Settings > Battery > Battery saver > Deep Doze settings.
Conclusion
Deep Doze is a powerful feature that can help extend battery life and reduce power consumption on Android devices. By understanding how Deep Doze works and customizing it to suit your needs, you can get the most out of this feature and enjoy a longer-lasting battery. Whether you’re a heavy user or just looking to squeeze out a few extra hours of battery life, Deep Doze is definitely worth exploring.

In conclusion, Deep Doze is a valuable feature that can help you get the most out of your Android device’s battery. By understanding how it works and customizing it to suit your needs, you can enjoy a longer-lasting battery and a better overall user experience.
What is Deep Doze in Android and how does it help in power saving?
Deep Doze is a power-saving feature in Android that helps to extend the battery life of a device by restricting the background activities of apps. When a device is in Deep Doze mode, it enters a low-power state where it stops all network activity, GPS, and Wi-Fi scans, and also restricts the CPU and memory usage.
This feature is particularly useful when the device is not being used for an extended period, such as when it is left idle overnight. By restricting the background activities of apps, Deep Doze helps to reduce the power consumption of the device, thereby extending its battery life. This feature is available in Android 6.0 (Marshmallow) and later versions.
How does Deep Doze mode get activated in an Android device?
Deep Doze mode is activated in an Android device when the device is left idle for a certain period, usually 30 minutes to an hour, and the screen is turned off. The device must also be stationary, meaning it is not moving, for Deep Doze to be activated. This is because the device uses the accelerometer to detect movement and will not enter Deep Doze mode if it is moving.
Once the device meets these conditions, it will enter Deep Doze mode, and the system will start restricting the background activities of apps. The device will also stop all network activity, GPS, and Wi-Fi scans, and restrict the CPU and memory usage to conserve power.
What are the restrictions imposed by Deep Doze on apps?
When an Android device is in Deep Doze mode, the system imposes several restrictions on apps to conserve power. These restrictions include stopping all network activity, GPS, and Wi-Fi scans, and restricting the CPU and memory usage. Apps are also not allowed to access the network, and their background activities are restricted.
Additionally, the system also defers all jobs and alarms scheduled by apps until the device exits Deep Doze mode. This means that apps will not be able to perform any tasks or wake up the device until the device is taken out of Deep Doze mode.
How does Deep Doze affect the performance of apps?
Deep Doze can affect the performance of apps in several ways. Since apps are not allowed to access the network or perform background activities, they may not be able to provide real-time updates or notifications. Additionally, apps may also experience delays in syncing data or performing tasks since the system defers all jobs and alarms scheduled by apps until the device exits Deep Doze mode.
However, most apps are designed to handle Deep Doze mode and will resume their normal functionality once the device exits Deep Doze mode. App developers can also use various APIs provided by Android to handle Deep Doze mode and ensure that their apps continue to function normally even when the device is in Deep Doze mode.
Can users customize Deep Doze settings in their Android device?
Yes, users can customize Deep Doze settings in their Android device to some extent. Users can enable or disable Deep Doze mode for specific apps, and they can also set the duration for which the device should be idle before entering Deep Doze mode.
