When you install a smartphone app, there's a good chance it will come with push notifications turned on by default. For example, Facebook's Messenger app will be able to pop up a notification whenever you receive a message on the service. Depending on how many messages you receive on Facebook, this could be quite a battery drain for your phone.
Not all apps have the option to disable notifications. For example, Facebook only gives you the option to turn off notifications for "1 Hour" or "Until 8am" -- there's no option to turn them off permanently. However, notifications can be disabled on a per-app basis in iOS, Android, or Windows Phone settings.
Tap the Settings icon. Then navigate to Notification Center, and scroll down to the app you'd like to change the notifications for. In this screen, you can choose the "Alert Style," which can be "None", "Banners", or "Alerts". Banners will appear at the top of the screen, while alerts pop up as a dialog box in the middle of the screen.
Below those options, you'll find on/off switches for a few more things. You can choose whether or not you'd like a badge displaying the number of unread notifications on the app's home screen icon, if you'd like a sound to play, and whether or not you want the alert to appear in Notification Center. In order to completely disable notifications for that app, all of these options must be turned off.
Go into Settings, then tap on "Apps". Tap on the app that you would like to disable notifications for, and then uncheck the "Show notifications" box. Android will display a warning that you won't receive alerts from this app. Tap "OK" to continue.
In the app list, tap Settings > Notifications, then tap an app from the list.
- Turn off "Show in action center".
- Uncheck the "Show notification banners" check box.
- Tap Notification sounds, and tap "none".
- Uncheck the "vibrate" check box
- Uncheck the "Show notifications in action center when my phone is locked" check box.
