For most people, having a phone with a long battery life is essential. The Galaxy S7’s 3600 mAh battery capacity may be Samsung’s biggest battery to date, but saving your battery power is still a good idea. Though you can extend your phone’s battery life by enabling Power Saving Mode for your Android device, Samsung has raised the bar by allowing users to set up battery optimization for individual apps on the Galaxy S7. Battery optimization for apps saves power by limiting or disabling the background data and refreshing processes and by turning off notifications for applications that you select. This tutorial will guide you through the process.
