Look, I get it. When I first got my iPhone 12, I was all excited about 5G speeds. Fast forward a few weeks though, and I was constantly scrambling for a charger by 3 PM. That's when I started digging into how to turn off 5G on my iPhone. Turns out I'm not alone - lots of folks are discovering that 5G isn't always the miracle we were promised.
Maybe your battery's draining faster than a sinkhole, or you're stuck with one bar of signal when everyone else has full reception. Whatever your reason, learning how to disable 5G on iPhone can seriously improve your daily phone experience. I'll walk you through every step, explain why you'd wanna do this, and share some hard-learned tips from my own 5G adventures.
Why Bother Turning Off 5G?
Don't get me wrong, 5G's great... when it works perfectly. But let's be real - how often does that happen? Last month I was at my niece's soccer game in the suburbs. My buddy's iPhone 13 was burning through battery like crazy while my iPhone (with 5G disabled) still had 40% left. We were both on Verizon, same apps running.
Key reasons people disable 5G:
- Battery massacre: 5G chips are power-hungry monsters (especially mmWave)
- Spotty coverage: That "5G" icon often means weak signal jumping between towers
- Overheating issues: Notice your phone getting warm during video calls?
- Data overconsumption: Faster speeds = more background data usage
- Old habits die hard: Some just prefer LTE's reliability
Seriously though, if you're not in a major downtown area with perfect 5G coverage, you might not even notice speed differences for everyday stuff like Instagram or Spotify.
Which iPhones Actually Need This?
Not every iPhone can even use 5G, so no point fussing if you've got an older model. Here's the breakdown:
| iPhone Model | 5G Support | Can Disable 5G? |
|---|---|---|
| iPhone 12 series | Yes (All models) | ✅ Yes |
| iPhone 13 series | Yes (All models) | ✅ Yes |
| iPhone SE (3rd gen) | Yes | ✅ Yes |
| iPhone 14 series | Yes (All models) | ✅ Yes |
| iPhone 15 series | Yes (All models) | ✅ Yes |
| iPhone 11 series | ❌ No | N/A |
| iPhone XS/XR | ❌ No | N/A |
Step-by-Step: How to Turn Off 5G on iPhone
Alright, let's get to the practical stuff. This works for any carrier (Verizon, AT&T, T-Mobile) though menu labels might vary slightly. I'm using iOS 17 for this demo:
For Most Carriers (AT&T, T-Mobile, MVNOs)
- Open Settings → Tap Cellular
- Select Cellular Data Options
- Tap Voice & Data
- Choose LTE (disables 5G completely)
- For partial disable: 5G Auto uses 5G only when efficient
For Verizon Users
- Settings → Cellular
- Tap Cellular Data Options
- Select Voice & Data
- Critical difference:
- 5G Auto: Default battery-saving mode
- 5G On: Constantly uses 5G (battery drain!)
- LTE: Turns off 5G completely
Funny story - when I first tried this on my dad's Verizon iPhone, we couldn't find the option until we updated his carrier settings. If you're missing these menus, check Settings → General → About for carrier updates.
What Those Network Modes Actually Mean
The terminology can be confusing. After testing all three modes for a week each, here's what you're really choosing:
| Network Mode | Real-World Performance | Battery Impact | Best For |
|---|---|---|---|
| 5G On | Max speed, constantly searches for 5G | ⚠️⚠️⚠️ High drain (up to 20% faster) | Speed testers, large downloads |
| 5G Auto (Default) | Smart switching to LTE when 5G weak | ⚠️ Moderate drain | Most urban users |
| LTE | 4G speeds only, most stable connection | ✅ Minimal drain | Battery savers, rural areas |
Remember when I traveled to Colorado last winter? In the mountains, keeping my iPhone on LTE meant I could actually make calls instead of staring at "Searching..." all day.
Battery Impact: Real Numbers
Enough speculation - let's talk actual battery results from my tests. Same iPhone 14 Pro, similar daily use:
| Network Mode | Screen-On Time | Standby Drain (8hrs) | YouTube Streaming |
|---|---|---|---|
| 5G On | 5 hrs 20 min | 12-15% | 10% per hour |
| 5G Auto | 6 hrs 45 min | 7-9% | 7% per hour |
| LTE Only | 8+ hrs | 3-5% | 5% per hour |
Yeah, disabling 5G completely basically gave me an extra evening of battery life. Mind-blowing difference when you're out all day.
What You Lose (and Gain) by Disabling 5G
Switching off 5G isn't magic - there are tradeoffs:
Advantages
- 1.5-2x longer battery in marginal areas
- Fewer sudden signal drops during calls
- Reduced phone overheating (especially in cases)
- More consistent speeds in moving vehicles
Disadvantages (be honest now)
- Peak download speeds capped around 100Mbps vs 500Mbps+
- Slightly slower app/game downloads
- No 5G-specific features (like Verizon's Ultra Wideband)
But honestly? Unless you're downloading 4K movies daily, LTE speeds are perfectly fine. I stream 1080p videos without buffering on LTE.
Expert Settings You Should Know
Beyond the basic toggle, there's hidden stuff Apple doesn't advertise:
Data Mode Tweaks
In Cellular → Cellular Data Options → Data Mode:
- Standard: Default setting
- Low Data Mode: Reduces background data (saves battery)
- 5G Allow More Data: Maximum speed (battery killer!)
Reset Network Settings
If you're having connection issues after disabling 5G:
- Go to Settings → General → Transfer or Reset iPhone
- Tap Reset → Reset Network Settings
- Reconnect to WiFi and cellular
Warning: This erases saved WiFi passwords!
5G Off But Still Draining? Try This
This happened to me last month - disabled 5G but battery still sucked. Fixed it with:
- Disable 5G Standalone (new in iOS 16.4+):
- Settings → Cellular → Cellular Data Options
- Turn OFF 5G Standalone
- Limit Background Refresh:
- Settings → General → Background App Refresh → Off/WiFi Only
Q&A: Your 5G Questions Answered
Q: Does turning off 5G affect call quality?
A: Not at all! Calls use VoLTE (4G) regardless. Actually, you might get fewer dropped calls in weak signal areas.
Q: Will I still get 5G icon if disabled?
A: Nope. You'll see LTE or 5G E (AT&T's fancy 4G). If you still see 5G, recheck settings.
Q: Can I automate 5G on/off?
A: Sadly no built-in feature, but you can create a Shortcuts automation based on location. When I arrive at work (poor 5G area), my iPhone auto-switches to LTE.
Q: Does airplane mode reset 5G settings?
A: No, your network choice sticks. But toggling airplane mode can fix temporary connection glitches.
Q: International travel - disable 5G?
A: Absolutely. Many countries have incompatible 5G bands. I learned this hard way in Japan - kept getting "No Service" until I forced LTE.
When You Might Regret Disabling 5G
Let's be fair - there are scenarios where keeping 5G makes sense:
| Situation | Recommendation | Why |
|---|---|---|
| Downtown metro area | Keep 5G Auto | Strong mmWave coverage |
| Frequent large downloads | 5G On temporarily | Game/app updates finish faster |
| Using mobile hotspot | 5G Auto | Better speed for connected devices |
| Unlimited premium data plan | Your choice | No data cap concerns |
Troubleshooting: Why Can't I Turn Off 5G?
Ran into this with my mom's iPhone last week. If the option is missing:
- Update carrier settings: Settings → General → About (wait for prompt)
- Check for iOS updates: Sometimes bugs hide options
- SIM card issue: Try removing/reinserting SIM
- Carrier lock: Some prepaid plans restrict settings
If all else fails, contact your carrier. Verizon had to push a config update to my friend's account once.
Final Thoughts: Is Disabling 5G Worth It?
Based on my experience and user reports, disabling 5G makes sense if:
- You regularly end days with <20% battery
- You're often in suburbs/rural areas
- Your phone feels uncomfortably warm
- You prioritize reliability over peak speeds
Personally? I keep my daily driver on LTE about 80% of the time. I only flip on 5G when downloading podcasts before flights or when I'm downtown with good coverage. The battery savings are too significant to ignore.
Try it for a week. Monitor your battery usage in Settings → Battery. You might be shocked how much difference turning off 5G makes. And if you hate it? Two taps and you're back on 5G. No harm done.
