The moment I activated the Jio 5G, 5g battery drain became my biggest problem. I would leave home with 100% at 9 AM, and by 2 PM it dropped to 35%. On 4G with the same usage, I still had 45% by evening. So yes, turning on 5G was draining the battery faster.
I tracked everything for 60 days using AccuBattery and the built-in Battery Usage stats. I tried a lot of hacks from online forums, but most did not work. After changing these 6 settings, my screen-on time went from 4.5 hours to 6.2 hours. Overall, it seemed to save around 40% battery in my case.

Why Does 5G Battery Drain So Fast? My 3 Finding
5G is a new technology, so it naturally uses more power. Based on my testing and research, these are the 3 main reasons:
1. Signal Hunting: 5G towers are still limited. The phone keeps switching between 5G and 4G. This constant switching consumes the battery. In my case, “Mobile Network Standby” showed 18-22% drain because of this.
2. Carrier Aggregation: For speed, the phone connects to 2-3 bands at once. More active antennas = more power usage. On 4G, usually 1 band is enough.
3. SA vs NSA Mode: Jio 5G runs on SA mode which is new. Airtel uses NSA mode that relies on a 4G core. During the initial rollout, SA mode seemed to use 3-4% extra battery in my area.
6 Settings That Actually Reduced My 5G Battery Drain With Data
I tested each setting for 3 days. I am only including the ones that made more than a 5% difference.
My 5G Battery Test Results: Before vs After Fixing Drain
| Setting Name | Where to Find | Battery Drain/hr Before | Drain/hr After | My Result |
| 1. Network Mode: 5G Auto | Settings > Mobile Network > Preferred network type | 14.2% | 9.1% | Shifts to 4G in weak signal. Helped reduce drain by 35% vs 5G ON |
| 2. Disable 5G When on WiFi | Developer Options > Mobile data always active OFF | 6.8% standby | 3.1% standby | At home on WiFi, standby drain was cut in half |
| 3. Turn Off Carrier Aggregation | ##4636## > Phone Info > Turn Off NR/LTE CA | 12.5% | 10.2% | Speed dropped from 450 Mbps to 280 Mbps, but battery lasted 18% longer |
| 4. Restrict Jio/Airtel App Background | Settings > Apps > Jio/Airtel > Battery > Restricted | 4.2% | 1.9% | These apps keep checking for 5G in background |
| 5. 5G Battery Saver Mode | Settings > Battery > More Settings > 5G Power Saving | 13.1% | 11.4% | Worked for everything except gaming. Saved around 13% |
| 6. Adaptive Connectivity OFF | Settings > Network & Internet > Adaptive Connectivity | 8.9% | 7.1% | Google feature that constantly searches for the best network. Turning it off helped |

2 Popular 5G Battery Hacks That Failed My Test
1. Airplane Mode Toggle: Was viral on Telegram. I tried it 3 times. Made 0% difference.
2. Locking Only 5G Band: Used _#_#4636#_#_ to set NR Only. The signal dropped and the phone heated up. The battery drained even faster. So 5G Auto felt better for me.
5G vs 4G Battery Life: My 12-Hour Real Usage Test
I tested 4G and 5G with the same routine from 9 AM to 9 PM. Both days had 5 hours screen-on, 30 min calls, 2 hours on WiFi.
| Network | Total Drain in 12hr | Screen-On Time | Mobile Network Standby | % Left at 9PM |
| 4G LTE Only | 58% | 5.1 hours | 6% | 42% |
| 5G Auto | 81% | 4.8 hours | 21% | 19% |
| 5G + All 6 Fixes | 63% | 6.2 hours | 9% | 37% |
So without fixes, 5G used 23% extra battery. After the fixes, the difference was only 5%. This is why the issue seemed fixable with settings.
When Should You Turn Off 5G to Save Battery? 3 Cases
1. While Traveling: Signal is weak in trains/buses. 5G heats the phone and drains battery. I switched to LTE Only. For related heating issues, you can also check this overheating phone solution.
2. Below 20% Battery: Turn off 5G and switch to 4G. It may give you 30-40 min extra backup.
3. Only WhatsApp/Calling: You do not need 5G. 4G is enough.
Conclusion
Look, 5G is new tech so it will use slightly more battery. But with the 6 settings above, the 5g battery drain problem became manageable on my phone. It was not solved 100%, but now it easily lasts the whole day.

Frequently Asked Questions
Q1. Does turning off 5G damage the phone?
No. I have been doing it for 2 months. The option is in Settings for a reason. It did not affect my phone or battery health. Only the speed drops.
Q2. Does the Jio 5G use more battery than the Airtel 5G?
In my Lucknow test, Jio on SA mode had 3-4% extra drain vs Airtel NSA. But it depends on the towers in your area. It can be the opposite for you. Test both for 1 day each.
Q3. Will turning off 5G cause call drops?
No. Calls still use 4G VoLTE. 5G is only for data. I did not face any call drop issues.
Q4. Will an update fix the battery drain issue?
It might. Companies keep optimizing networks. But until a fix arrives, these 6 settings should help. In my case, the August 2026 update improved battery by around 7%.
