Even after Android 4.1 I tried using the application "Doze" which can obtain the effect of 6.0 battery power saving function "Doze"

Android 6.0 Marshmallow has a deeper sleep function "Doze" that restricts data communication while sleeping to minimize battery consumption to the utmost. This Doze similar power saving function is available on Android OS 4.1 or later Android OS "DozeSince it was released, I tried using it at once.

On Google Play "DozeSearch "and tap" Install ".


Tap "I agree".


When installation is completed, tap "Open" to launch the application.


This is Doze's initial launch screen. The owl caught in a branch is closing her eyes. To activate Doze's power saving function, tap "Get into Doze".


Check "I will consider this application to be reliable" and tap "OK".


Then the owl opened his eyes and switched to the power saving mode of "Doze". Doze does not require anything in particular, it is an application that simply turns on the power saving mode and it is OK.


It is still possible to exclude applications that you want to keep active while deep sleeping. Tap the gear icon at the top right of the screen.


The application list is displayed like this.


Tap "+" icon of application you want to keep the function and change to "check mark" OK.


To turn off the function of Doze, tap "Quit Doze" at the bottom of the screen.


Tap "Yes, quit" to stop Doze.


So, I tried using Andperid 4.4.2 's Xperia Z Ultra (SOL 24) to try Doze' s effect. If you leave for 1 hour with the Doze application turned on after full charge, after 1 hourBattery MixThen I was able to check 2% battery consumption.


When Doze was turned off and left for 1 hour from full charge, the result also decreased by 2%. Due to the time being too short, it was not possible to check the difference by ON / OFF of Doze.


In the application description on Google Play, there is "2. Doze supports Android 4.1 or above. In the long run it will support more Android versions. Power-saving mode is available in Android 5 only." And the application is Android Although it corresponds to 4.1 or higher, at the time of article creation, it is said that Power - saving mode is only Android 5. So, I tried it at Galaxy S 6 edge of Android 5.0, but again no significant difference was found by leaving for 1 hour.
