Use Greenify’s Aggressive Snooze Mode to Conserve Even More Battery on Android
Android ( 6.0+ ): The nap mode on Android Marshmallow is a miracle that can boost your device’s battery by a ton when it hasn’t moved for a long time. Greenify can further increase these savings.
As the tips site How-To Geek explains, the experimental Aggressive Doze Greenify feature causes your phone to go into normal Doze mode in a much shorter time frame. While Doze is active, you will only receive periodic updates for your notifications, although you can whitelist certain apps if you need them all the time.
