How to turn 5G on or off on iPhone (and switch to LTE)
5G Auto is the best choice for most people. Switch to LTE when 5G is patchy where you live, or to save battery.
The fix
Turn 5G on or off
- 1
Open Settings and tap Cellular (Mobile Data in some regions).
- 2
Tap Cellular Data Options, then Voice & Data.
- 3
Pick a mode.
LTE: 5G off. 5G Auto: 5G when it makes a difference (recommended). 5G On: always 5G when available.
What the network icons mean
- 5G UW, 5G UC or 5G+: fast high-band or mid-band 5G, depending on the carrier.
- 5G: standard 5G, often similar to LTE speeds.
- LTE or 4G: the previous generation, very reliable.
- E or 3G: very slow backup networks, usually a sign of weak signal.
Frequently asked questions
Does turning off 5G save battery?
Yes, especially where 5G coverage is weak and the iPhone keeps searching for it. In areas with strong 5G, 5G Auto already balances speed and battery.
Why don’t I see 5G options?
5G needs an iPhone 12 or later, a 5G plan and carrier support. If Voice & Data only shows LTE, check with your carrier.
