iPhone users can improve battery and security via wireless settings

Users of mobile devices, particularly iPhones, can improve battery life and security by managing wireless connections more effectively. On iOS 18, simply tapping the Bluetooth icon in the Control Center may only disconnect existing devices while leaving the function active in the background, continuing to consume power. To fully deactivate Bluetooth, users can utilize the Shortcuts app to create a toggle that completely shuts the service off.

Similarly, leaving Wi-Fi enabled while traveling can pose security risks, such as exposure to fake hotspots or the leaking of location data through saved network directories. The Federal Office for Information Security (BSI) recommends activating wireless interfaces like Bluetooth, Wi-Fi, and NFC only when necessary. iPhone users can automate these processes using the Shortcuts app to turn Wi-Fi off automatically when leaving a specific location.
