Android Battery Optimization Notifications. Android marshmallow battery optimization is the front end for you to control doze mode and app standby, although for most users doze mode and app standby just work out of box without any user intervention. Open the settings menu on your device and tap device maintenance.
Disable battery optimization for the app to work properly. Remember, battery optimized apps are partly disabled and can’t pull notifications for you. Additionally, if your device’s android skin (xiaomi miui, huawei emui, samsung one ui) has a manager that aggressively kills apps in the background, make sure to whitelist apps in order to.
It's highly recommended that you disable this setting for messaging and chat applications, as untimely notifications for these can have a very negative impact on our personal and professional lives.
As explained in top 12 new features of android marshmallow, doze and app standby greatly increased the battery life in android marshmallow devices. Battery optimization helps conserve battery power on your device and it is normally turned on by default, but it can always be turned. Battery optimization is turned off as well as do not disturb and it still happens. Usually, it’s either the battery optimization issue or problem with the notification access.
