How to Turn Off 5G on an iPhone 15

Turning off 5G on an iPhone 15 is quite simple: go to Settings, tap on Cellular, then Cellular Data Options, and finally select LTE/4G instead of 5G as your preferred data mode. This quick switch helps you stay in control of your phone’s connectivity and potentially save on battery life.

After you complete this action, your iPhone 15 will stop using the 5G network and will instead connect to LTE/4G. This may lead to slower internet speeds, but it can conserve battery life and might improve your phone’s performance in areas with poor 5G coverage.

A Step by Step Tutorial

Before we dive into the steps, let’s clarify what we’re aiming to accomplish here. These instructions will guide you through disabling 5G on your iPhone 15, which can be handy for preserving battery life, avoiding data overages, or maintaining a stable connection when 5G is sketchy.

Step 1: Open Settings

Navigate to the Settings app on your iPhone.

Opening Settings is your gateway to customizing your iPhone experience, from wallpaper to Wi-Fi and, of course, cellular options.

Step 2: Tap on Cellular

Select the Cellular menu option in Settings.

This is where you’ll find all things related to your phone’s data connection – think of it as mission control for managing how your iPhone connects to the cellular network.

Step 3: Choose Cellular Data Options

In the Cellular menu, tap on Cellular Data Options to proceed.

Digging into this menu brings you closer to the heart of your phone’s data settings, allowing you to tweak how your iPhone uses the cellular network.

Step 4: Select LTE/4G

Finally, tap on Voice & Data and choose LTE/4G instead of 5G as your preferred data mode.

Switching to LTE/4G tells your iPhone, “Hey, let’s give 5G a break,” ensuring you connect using a different, sometimes more reliable, network.


Choosing to turn off 5G can offer several advantages, depending on your situation and needs.

Benefit 1: Battery Life Extension

Using LTE/4G can extend your iPhone’s battery life compared to 5G.

5G can be a power-intensive process, and sticking to LTE can be a battery-friendly alternative, especially when you’re out and about all day.

Benefit 2: Data Usage Management

It may help manage your data usage more efficiently.

Since 5G speeds can encourage more data consumption, switching to a slower network might help you avoid burning through your data cap too quickly.

Benefit 3: Increased Stability in Low 5G Areas

Switching to LTE/4G can lead to more stable connections in areas with poor 5G coverage.

LTE networks are more mature and widespread, offering a stable connection in places where 5G is still making its mark.


There are some potential downsides to consider before you flip the 5G switch off.

Drawback 1: Slower Data Speeds

You might experience slower data speeds on LTE/4G.

Turning off 5G means saying goodbye to those ultra-fast download and upload speeds, at least for a while.

Drawback 2: Missed 5G Advancements

You may miss out on the latest advancements that come with 5G networks.

5G technology is constantly evolving, and disabling it could mean you won’t benefit from these improvements until you switch back.

Drawback 3: Manual Switching

You’ll need to manually switch back to 5G to enjoy its benefits when needed.

Unlike some settings that adapt automatically, this is one you’ll have to remember to revert when you want those 5G perks back.

Additional Information

Turning off 5G on your iPhone 15 isn’t a permanent change – it’s more like putting it on pause. Remember that network conditions can change, and what’s true for 5G coverage and performance today may not hold tomorrow. If you’re a frequent traveler or live on the edge of a 5G area, you might find yourself toggling between 5G and LTE/4G quite often.

Another tip is to keep an eye on iOS updates. Apple often includes improvements to how your iPhone manages battery life and connectivity, which could make using 5G less of a drain in the future. Also, consider monitoring your data usage. Sometimes, what seems like a network issue is actually a data limit problem.


Here’s a quick recap of how to turn off 5G on an iPhone 15:

  1. Open Settings.
  2. Tap on Cellular.
  3. Choose Cellular Data Options.
  4. Select LTE/4G.
