Google Doze

Google introduced a feature called Doze, with the release of Android 6.0 Marshmallow. Normally Android apps run in the background, checking for

• checking for notifications.
• receiving and installing updates

But, it is ok if the phone is being used. But if your device is idle, yet apps are running in the background, then it will drain the battery.
Here is when Doze comes to action. Doze only works when your phone is completely still.

That means

• Phone has to be completely motionless/hibernates.
• You shouldn’t carry it in the pocket. (Doze will detect motion through                                            accelerometer and won’t work)
• only high priority notifications/phone calls and messages are allowed to run.
• Apps will not constantly sync in the background.

  Exceptions On which Doze Won’t Work

We have to manually set Apps to optimized or non-optimized so that unused Apps would sleep.Hence, battery life will stretch.

Notifications of Apps set to “High priority” will come through, even when the phone is in Doze mode.
In case of

• Incoming phone call
• Text Messages
• Messages from Phone’s Network provider
• Alarms

Doze will allow these above-mentioned applications to wake the device and let the user know of incoming notifications.

How To Set an App as Optimised, So As To Make Doze Work

Well, like we mentioned above we can select which Apps we need to run in the background and which Apps needed to be optimized.

Step-1  on your Android device, go to Settings > Battery

Step-2 Tap the menu button.

Step-3 Tap Battery optimization.

By default, every app will be optimized, and you’ll see the phrase “Optimizing battery use” in the list. In addition to that, You can Optimize the Apps according to your requirement.

To prevent an app from dozing, tap it in the list and select “Don’t optimize.”
Android will allow that app to run in the background, even while your device is dozing.

Google Play Services: Prime Culprit for Battery Life Reduction

Most noteworthy fact about Google Play Service is it always runs in the background and contributes to a steady loss of battery.

In addition to that, Doze feature does not work on Google Play Service.
In simpler words, we cannot optimize the Google Play Services application.

Even if we optimize other apps and our device enters Doze mode, Google Play Service is still running in the background.

If You want to see a list of all apps installed on your device,

Tap the “Not optimized” menu and select “All Apps”.

And yes You guessed it right.You can see Google Play Services on that list. It would mention against Google Play Service that “Battery Optimization Not Available” !!!

So, why there is no battery optimization option available for it ??!

And the Question of the day, how to stop Google Play Services from running in the background ??

Why Google Play Services Optimization Option Is Not Available

To make Google  Play Services optimized, we have to remove the whitelisting.

So, how to do that?
