Closing unused apps can prevent them from consuming resources and battery power in the background. While iOS is designed to manage apps efficiently, manually closing those that you are not actively using can further minimize battery usage.
Turning off unused connectivity features like Wi-Fi, Bluetooth, and AirDrop when they are not needed can help conserve battery life. These features often keep searching for available connections, which can lead to increased battery consumption.
