3. Stop closing apps in multitasking
Most people believe that closing the apps would save battery by making them stop running in the background. iOS is designed to freeze most of the apps in the position you left them unless the Background App Refresh is enabled. So closing them in a regular basis would result in losing more power as the memory of the device will have load them back again to close them. Remember not to close the apps in the multitasking menu too often.
