How to Disable Gmail on an Android
As convenient as it is to have a mobile device that keeps you connected and up-to-date, you may reach the point that you prefer not to constantly receive and clear Gmail notifications. Also, if you disable Gmail's synchronization feature, you can save on data usage every month. It only takes a few moments to disable synchronization, though you'll still have the ability to manually update your Gmail messages.
Setting your Android device to stop synchronizing only takes a few taps on the screen. From within the Gmail app, you first need to tap the menu button, three horizontal lines in the corner of the screen. Next, tap "Settings," and then choose which account you don't want automatically synchronizing. Finally, tap the "Sync Gmail" option to remove the check mark beside it and disable synchronization.
In the future, if you want to check Gmail on your device, you can do so manually in the Gmail app or by using your Web browser. Within the Gmail app, when you're viewing your preferred Gmail account, just tap the refresh button, which is an icon with two arrows in the shape of a circle. Alternatively, if you go to the Gmail website in your browser, you will see all of your most recent Gmail messages.
