Battery Optimization for Apps
When you have connections such as Wi-Fi on while the phone is in sleep mode, some apps may still
continue to use the battery. Starting from Android 6.0, battery optimization is enabled for all apps by
default which helps prolong battery standby time when you're not using the phone.
The phone needs to be sitting idle for an extended period of time before battery optimization takes
effect.

If there are apps that you don't want battery optimization enabled, you can turn the feature off in
those apps.

the battery such as the display and data connection.

extend battery life longer. In this mode, standby time can last longer than usual, and you can only use
the most basic functions such as phone calls, text messaging, and email.
