The new 5G wireless standard holds great promise in speeding up your iPhoneâ€™s wireless data transfer rates, but it also can take a heavy toll on your battery, quickly draining battery life while enabled. Hereâ€™s how to turn it off when you donâ€™t need it.
First, open Settings on your iPhone.
In Settings, tap â€œCellular.â€�
In â€œCellular,â€� tap â€œCellular Data Options.â€�
In â€œCellular Data Options,â€� tap â€œVoice & Data.â€�
In â€œVoice & Data,â€� select â€œLTEâ€� from the list to disable 5G completely.
(Alternately, you can select â€œ5G Autoâ€� from this list, which will let the iPhone automatically deactivate 5G to save battery life when itâ€™s not needed.)
Note: If your iPhone doesnâ€™t include 5G hardware, you wonâ€™t see 5G as an option here. Apple added 5G support when it launched the iPhone 12, iPhone 12 mini, iPhone 12 Pro, and iPhone 12 Pro Max in 2020. Older iPhones do not support 5G.
After that, exit Settings. 5G is now disabled on your iPhone. If you ever need to turn it back on, just revisit â€œSettingsâ€� > â€œCellularâ€� > â€œCellular Data Optionsâ€� > â€œVoice & Dataâ€� and select â€œ5G Onâ€� or â€œ5G Auto.â€�
