A powerful processor and a high-refresh-rate display are essential for a great gaming phone, but they are worthless if your battery dies in the middle of a crucial match. For any serious mobile gamer in India, battery endurance is a top priority. On paper, the top contenders in the sub-₹40,000 segment—the iQOO Neo 9 Pro, Poco F6, and Realme GT 6—all promise all-day power.
But how do they hold up under the intense, non-stop pressure of a real gaming marathon? We decided to find out. We took these three performance champions, charged them to 100%, and put them through a grueling, side-by-side battery drain test to crown the true endurance king.
The Test Methodology
To ensure a perfectly fair and controlled comparison, every phone was set up identically. This is a test of pure hardware and software optimization.
- Game: Battlegrounds Mobile India (BGMI)
- Graphics: “Smooth” graphics with “90 fps” frame rate setting enabled.
- Brightness: Manual brightness locked at 50% for all devices.
- Audio: Volume set to 50% through wired earphones to keep speaker usage consistent.
- Connectivity: All phones connected to the same 5GHz Wi-Fi network, with SIM cards removed.
- Test Duration: 3 hours of continuous TDM and classic matches.
The Results: Hour-by-Hour Breakdown
We recorded the battery percentage of each phone at the end of every hour to track the drain rate.
After 1 Hour of Gaming: The first hour is where phones show their initial efficiency before heat becomes a major factor. All three performed exceptionally well.
- Realme GT 6: 84% remaining (16% drain)
- iQOO Neo 9 Pro: 83% remaining (17% drain)
- Poco F6: 82% remaining (18% drain)
Initial Thoughts: The Realme GT 6, with its largest 5500mAh battery, took an early, albeit small, lead as expected. All phones remained relatively cool.
After 2 Hours of Gaming: This is where thermal management starts to impact battery consumption. A hotter phone uses more power.
- Realme GT 6: 66% remaining (34% total drain)
- iQOO Neo 9 Pro: 65% remaining (35% total drain)
- Poco F6: 61% remaining (39% total drain)
Mid-game Analysis: The iQOO Neo 9 Pro’s superior cooling system started to show its value, keeping its drain rate almost identical to the Realme GT 6 despite having a smaller battery. The Poco F6 began to consume slightly more power as it ran warmer.
After 3 Hours of Gaming: The final hour separates the champions from the contenders.
- iQOO Neo 9 Pro: 48% remaining (52% total drain)
- Realme GT 6: 47% remaining (53% total drain)
- Poco F6: 40% remaining (60% total drain)
Final Analysis: In a surprising turn, the iQOO Neo 9 Pro pulled ahead to win. Despite the Realme GT 6 having a 440mAh larger battery, the iQOO’s combination of a power-efficient Snapdragon 8 Gen 2 and a more effective cooling system resulted in less power consumed over the long run.
Final Comparison and The Winner
| Phone Model | Battery Size (mAh) | Battery After 1 Hr | Battery After 2 Hrs | Battery After 3 Hrs |
| iQOO Neo 9 Pro | 5160mAh | 83% | 65% | 48% |
| Realme GT 6 | 5500mAh | 84% | 66% | 47% |
| Poco F6 | 5000mAh | 82% | 61% | 40% |

Winner: iQOO Neo 9 Pro
The results are clear. While the Realme GT 6 has fantastic endurance, the iQOO Neo 9 Pro is the ultimate battery champion for marathon gaming sessions. Its victory proves that software optimization and thermal efficiency are just as important as raw battery capacity. It consistently consumed less power under sustained load, making it the most reliable companion for gamers who never want to quit before the match is over.
The Poco F6, while placing third in this specific test, still offers very respectable battery life, especially considering its aggressive price point. However, for those who prioritize endurance above all else, the choice is between iQOO and Realme, with iQOO taking the crown for efficiency.
