Snapdragon 8 Gen 4 vs A18 Pro – Delta Force Mobile Test (OnePlus 13 vs iPhone 16 Pro Max)
Introduction: The Ultimate Mobile Gaming Showdown
With the release of Delta Force Mobile—a visually intense and tactically demanding game—it’s the perfect opportunity to test the gaming prowess of two of the most powerful smartphones of 2025: the OnePlus 13 featuring the Snapdragon 8 Elite chip, and the iPhone 16 Pro Max housing Apple’s latest A18 Pro chip.
Mobile gamers have long debated between Android and iOS when it comes to peak performance, thermal stability, and frame rate consistency. So in this head-to-head test, we pushed both devices to their limits using Delta Force Mobile at max graphics settings, with full effects enabled, in real-world, multiplayer conditions.
Let’s break down the battle—frame by frame.
🎮 Test Overview: Graphics Settings & Performance Baseline
Before diving into FPS graphs and thermal charts, it’s important to understand the testing conditions. Both devices were tested under the same settings:
- Graphics Settings: Maxed out (Ultra), all visual effects ON
- Frame Rate Cap: 60 FPS (locked by the game engine at max settings)
- Game Mode: Warfare Mode, with 48 real players per match
- Duration: One full match per device (approx. 10+ minutes)
- Environment: Indoor controlled temp (approx. 22°C / 72°F)
Despite being capped at 60 FPS, the intensity of Delta Force Mobile’s real-time explosions, particle effects, and multiplayer mechanics makes it a perfect stress test.

🔄 Frame Rate Stability
After collecting frame-by-frame data from both devices:
- iPhone 16 Pro Max averaged 59.7 FPS
- OnePlus 13 averaged 58.4 FPS
Both are impressive, but Apple clearly squeezed out a slight edge in terms of average sustained performance. However, that’s not the full story.
🔥 Thermal Performance
This is where the gap begins to widen:
- OnePlus 13: Peak temps ranged 38°C – 39°C
- iPhone 16 Pro Max: Reached 41°C – 42°C
Although the iPhone managed a higher average frame rate, the OnePlus 13 stayed cooler, even under extended heavy load. This makes a real difference during long sessions—especially in how comfortable the device feels in-hand.
🚨 Thermal Throttling Behavior
Here’s the twist: despite the cooler performance, the OnePlus 13 showed aggressive software-based FPS throttling once internal temps crossed 37–38°C. This means it proactively reduced performance to prevent heat buildup, which may explain the FPS drop during long matches.
In contrast, Apple’s A18 Pro chip also throttles—but it’s far less aggressive, maintaining smoother performance at slightly higher thermal thresholds.
| Metric | OnePlus 13 | iPhone 16 Pro Max |
|---|---|---|
| Avg FPS | 58.4 | 59.7 |
| Max Temp | 39°C | 42°C |
| Throttling | Early, Aggressive | Moderate |
| Performance Drop | ~2 FPS | ~0.3 FPS |
🎯 Gaming Experience: Real-Time Gameplay
Throughout the match, both phones provided fluid gameplay, accurate aiming, fast response, and vivid graphics. From intense firefights to large explosions and close-quarter combat, the experience felt console-like on both platforms.
🧠 AI, Shaders & Load Times
- iPhone 16 Pro Max seemed to load textures slightly faster, likely due to iOS optimization and Apple’s unified memory architecture.
- OnePlus 13 excelled in temperature control, never becoming uncomfortably warm.
📊 Conclusion: A Close Battle
After 10+ minutes of non-stop multiplayer combat, here’s how both devices stack up:
✅ iPhone 16 Pro Max Pros
- Slightly better average FPS
- Consistent performance over time
- Smoother thermal scaling
✅ OnePlus 13 Pros
- Superior thermal control
- Cooler device during gameplay
- Less battery drain during test session
Both devices performed admirably, and the differences may only matter for hardcore mobile gamers or streamers. For casual and even competitive gamers, either phone offers a top-tier experience.
🔚 What to choose: It’s a Tie—for Now
If you prioritize thermal efficiency and comfort, the OnePlus 13 is a winner. If you want the smoothest gameplay with minimal frame drops, the iPhone 16 Pro Max edges it out.
In the end, it comes down to Android vs iOS preference, because in terms of raw gaming power, both phones are flagship beasts.
