Tap the application you would like to close ( if the app does not appear, tap Show Cached Processes, and tap the application). Then, tap Stop. If a System Service note appears, go through it and tap OK. The application should be closed now. Repeat for all the applications.

If your device is experiencing short battery life, the change of one of these settings may improve this issue:
To conserve battery life you can reduce backlight brightness and backlights timeout. From the home screen, swipe down the Status Bar. Tap Settings > Display. Tap and drag Brightness slider to the lowest comfortable level (if you would like the device to automatically adjust the brightness, check Auto).
Tap Screen Timeout > Tap the lowest comfortable screen timeout setting.
Do not use live wallpapers, these may reduce battery significantly. To change wallpaper, scroll from Settings to and tap Wallpaper> Choose a static image > tap Set as a Wallpaper.
The use of WI-Fi can extend your battery life significantly. However, leaving your Wi-Fi, Bluetooth and Location settings on when they are not in use can drain your battery faster. Swipe down the Status bar, tap to turn off Wi-Fi, Bluetooth. To exit, press Home key.

Turning off vibration can improve battery life. From the Settings screen, scroll to and tap Sounds and Notifications. Tap Vibrations. Tap the Vibrate when ringing, Vibration Feedback, and Keyboard vibration switches to OFF.
Lastly, Samsung provides different battery save modes that you can activate as needed. To do so, Scroll to and tap Battery > Power Saving Mode > Tap switch to ON > tap the back key. Another option is to turn on Ultra Power Saving Mode (this setting will apply a grayscale theme, reduce the number usable apps, turn off Mobile Data when the screen is off, and turn off Wi-Fi and Bluetooth configurations.) To leave Ultra Power Saving mode Off press the Home key.
Following these configuration your device should improve the battery life.

Not super helpful. Does not help out with why my Tab A thinks it is an S7, does not help me figure out why the tablet keeps moving things from external to internal then losing them because of no room, etc. Samsung tablets used to be good, but these new ones are terrible
