Regarding the battery of an Android smartphone, we have seen the best apps to save battery, which are worth trying even if they are not so reliable, and above all the configurations to extend the battery of the smartphone to the maximum, which are valid for each smartphone. Since battery life is always a problem, Google, in the latest Android 6 Marshmellow version, has set up a new automatic battery optimization feature, called in English Doze .
This new smart feature of Android 6 works so that if the smartphone is not in use and with the screen turned off, all applications running and in the background are automatically put into saving mode. In the end, and I can confirm it from direct experience, the battery really lasts longer. The battery optimization can be found from the settings -> Battery, by tapping the options button at the top right. The screen shows all the apps and allows you to see those "Without optimization", for which the energy saving function is disabled. In fact, by touching an app in this list, you can exclude some apps from optimized battery use, if you notice that it no longer works well.
You can get the same battery optimization function as Android 6 on other smartphones with Android 5 or 4 "> Doze, free, compatible with Android from version 4.1 .
The application is activated automatically after installation and, just like the battery optimization in Marshmallow, in the settings you can exclude some apps from saving energy. Being an external app, the Android System and Google Play Services applications must be absolutely excluded.
The difference between the application and the functionality of Android 6 is that Doze can be activated and deactivated at its discretion and there is no need to wait two hours before the energy saving mode is activated. When the screen is off, Doze prevents applications from sending or receiving data, without however disabling the data connection or Wi-Fi. This extends the battery life significantly. From the reviews I have noticed how many users appreciate this free application, also for its option to plan the activation of Doze at night.
The optimization of the battery and the Doze app is different from the energy saving of Android, which automatically deactivates any superfluous activity when the battery goes below 15% or 5% or after two hours of stanby.
