Switch from 5G to 4G on iPhone

Experiencing poor 5G signal? Learn how to switch your iPhone from 5G to 4G LTE for a more stable connection. Save battery life too.

Last updated: March 2026 • Reviewed by Compare The Networks

5G coverage is expanding but still patchy in many areas. If your connection is unstable or your battery is draining fast, switching to 4G LTE can help.

Steps

  1. Go to Settings > Mobile Service
  2. Tap your SIM or eSIM line
  3. Tap Voice & Data
  4. Select LTE (this disables 5G)

Options Explained

SettingWhat it does
5G OnAlways uses 5G when available (uses more battery)
5G AutoUses 5G when it won’t significantly impact battery life
LTE4G only — most stable, best battery life
Tip: “5G Auto” is the best default for most business users. It gives you 5G speeds when signal is strong but falls back to 4G to save battery.

You can switch back to 5G at any time by following the same steps and selecting 5G On or 5G Auto.
