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.
