5G Video Call Heating Fix :
Have your ever experienced smartphone overheating while you are on a long voice call in Jio/Airtel’s 5G network? You’re not the only one. A number of Android users have reported that the device gets heated up during VoLTE or VoNR calls, more so on latest high-end 5G smartphones.
If you’ve been asking yourself Why Is My Smartphone Heating Up While I’m Using 5G VoLTE Services? then know that it’s usually due to a combination of signal strength, network conditions, device settings and modem activity. While you should expect some warming up, too much heat can affect battery life, performance, and user experience.
In this article, we will see Why is My Smartphone Getting Heated Over 5G VoLTE Calls? along with useful Jio, Airtel settings tricks to prevent it from heating the phone unnecessarily.
Is Smartphone Heating During 5G Calls Normal?
Yes, to a certain extent. Modern smartphones contain multiple components that become active during a voice call, including:
- 5G Modem
- Network Antennas
- Processor
- AI Noise Cancellation Engine
- Microphone Processing System
- Background Apps
When all these systems work together, some heat generation is expected. However, excessive heating may indicate inefficient network conditions or unnecessary background activity.
Why is My Smartphone Heating Up During 5G VoLTE Calls?
Several factors can contribute to smartphone heating during voice calls.
1. Weak 5G Signal Strength
This is one of the most common causes. When your phone struggles to maintain a stable 5G connection, it continuously boosts modem power to communicate with nearby towers.
Signs
- Frequent network switching
- Reduced call quality
- Increased battery drain
- Device heating near the top section
Users asking Why is My Smartphone Heating Up During 5G VoLTE Calls? often discover that weak signal strength is the primary culprit.
2. Continuous 5G and 4G Network Switching
Many smartphones still switch between:
- 5G
- 4G LTE
- VoLTE
- VoNR
during voice calls.
This process requires additional modem activity.
Common Scenario
- Phone connects to 5G.
- Call begins.
- Device falls back to LTE.
- Network switches again.
Repeated transitions increase power consumption and heat generation.
3. VoNR (Voice over New Radio) Processing
Many newer phones support VoNR, which allows calls directly over 5G networks.
While VoNR improves call quality, it may increase modem workload under certain conditions.
Especially when:
- Network coverage is inconsistent
- Signal strength fluctuates
- Carrier optimization is incomplete
4. Background Apps Running During Calls
A surprising number of users make calls while:
- Watching YouTube
- Using Instagram
- Running WhatsApp
- Browsing Chrome
- Playing games
This places additional stress on the CPU and modem simultaneously.
The result?
👉More heat.
5. High Screen Brightness
Many users take calls outdoors.
Under bright sunlight:
- Auto brightness increases
- Display power consumption rises
- Internal temperature climbs
AMOLED displays can contribute significantly to overall heat output.
Jio Users: Settings Tweak to Reduce Heating 🎫
If you’re a Jio user wondering Why is My Smartphone Heating Up During 5G VoLTE Calls? try these adjustments.
Enable Smart Network Selection
Settings → SIM Card → Preferred Network
Choose:
- 5G Auto
instead of forcing:
- 5G Only
Why?
The phone can intelligently switch networks when needed instead of continuously searching for a weak 5G signal.
Disable Unnecessary Dual SIM Activity
If you use:
- Jio 5G
- Secondary SIM
the phone operates two radio systems simultaneously.
Try temporarily disabling the secondary SIM and observe temperature changes.
Update Carrier Settings
Many manufacturers release network optimization updates.
Check for:
- System updates
- Carrier service updates
- Security patches
These often improve modem efficiency.
Airtel Users: Settings Tweak to Reduce Heating 🎫
Airtel users can also optimize network behavior.
Avoid Forcing 5G in Weak Coverage Areas
If Airtel 5G coverage is inconsistent:
- Settings → Mobile Network
Select:
- 5G/4G Auto
instead of locking the phone to 5G. This reduces unnecessary tower hunting.
Disable Wi-Fi Scanning
Many Android devices continuously scan for Wi-Fi networks.
Go to:
- Settings → Location → Scanning
Disable:
- Wi-Fi Scanning
- Bluetooth Scanning
This reduces background activity.
Reduce Heating During Long Calls
Here are some practical adjustments.
Lower Display Brightness
A simple brightness reduction can noticeably lower device temperatures.
Recommended
- 30–60% brightness during calls.
Remove Thick Phone Cases
Some rugged cases trap heat.
If your phone heats excessively:
- Remove the case temporarily
- Check temperature changes
Better airflow often helps.
Close Background Apps
Before a long call:
- Close gaming apps
- Close social media apps
- Stop video streaming
This allows more resources to focus on call processing.
Does Battery Health Affect Call Heating? 📞
Yes.
Older batteries:
- Generate more heat
- Charge less efficiently
- Deliver unstable voltage
If your phone is more than two years old, battery degradation may contribute to increased temperatures.
Which Phones Heat More During 5G Calls?
Heating varies depending on:
- Processor
- Older 5G chipsets
- Entry-level modems
- Less efficient processors
Cooling System
Premium devices generally include:
- Vapor chambers
- Graphite cooling layers
- Better thermal management
Budget smartphones may warm up faster under identical conditions.
When Should You Be Concerned?
Mild warmth is normal.
However, seek professional inspection if:
Warning Signs
- Device becomes too hot to hold
- Call drops repeatedly
- Battery drains unusually fast
- Performance throttling occurs
- Temperature warnings appear
These symptoms may indicate hardware or battery-related issues.
Best Settings to Reduce 5G VoLTE Call Heating :🔥
Recommended Configuration :
- 5G Auto Mode
- Updated Software
- Moderate Brightness
- Background Apps Closed
- Strong Signal Area
- Wi-Fi Scanning Disabled
- Avoid 5G Only Mode
These settings typically provide the best balance between connectivity and thermal performance.
Final Verdict :🙌
If you have been facing the issue of why is my smartphone heating up during 5g volTe calls? then hold on with this is probably due to signal strength, modem workload, network switching and background activity, rather than any hardware malfunction. Jio and Airtel users both can minimize heating by switching to auto network selection from forced mode 5G, reduce screen brightness, and keep software updates.
In most cases you can achieve considerable improvement to the thermal performance by just changing several settings. After reading What Causes a Smartphone to Heat Up While Calling? and trying these simple and practical Jio and Airtel tips, you can expect not just better calling experience but also longer battery life and less hot of your phone.
