Turning off the individual connections that your device automatically makes will save battery power and keep your iPad running longer.
If you have an iPad with a cellular connection, bear in mind that those connections can have an affect on your device’s battery life. 3G and 4G signals may be quicker, but they also have a significant impact on your battery, especially if you’re in an area with poor signal.
To turn it off, open Settings, select Cellular (Mobile) and turn off the Enable 3G or Enable 4G option. You can also turn off Cellular Data to restrict all data use to Wi-Fi if you’re currently connected to a wireless network.
If poor signal is affecting your battery life you can also enable Airplane Mode from Control Center or the Settings app. Remember to turn it off again if you want to receive communication from others and notifications from apps.
To disable all connections (including Bluetooth and Wi-Fi), enable Airplane Mode from Control Center or the Settings app. Airplane Mode is also handy if you’re out of the country and want to avoid heavy network charges or save battery without having to turn off your device. Remember to turn it off again if you want to receive communication from others and notifications from apps.
