How iPhone 13 Pro Max Performs in PUBG: FPS Test Explained

Gamers love to know whether their device can keep up with the chaos of PUBG Mobile. The iPhone 13 Pro Max, with its A15 Bionic chip and ProMotion display, promises smooth action, but the proof lies in the numbers. Below we break down the FPS results, the factors that shape them, and a few practical tweaks to squeeze every extra frame out of the phone.

Why FPS Matters in PUBG

First‑person shooters are unforgiving; a dip of just a few frames can turn a winning clutch into a missed shot. In PUBG, where you’re constantly scanning the horizon, tracking moving enemies, and reacting to explosions, a steady 60 FPS feels buttery, while anything below 45 FPS can feel choppy.

• Visual smoothness: Higher FPS reduces motion blur, making enemies easier to spot.
• Reaction time: More frames give you fresher information, shaving milliseconds off your response.
• Battery impact: Pushing the GPU hard burns power, so balancing FPS and endurance is key.

Test Setup and Conditions

All measurements were taken on a brand‑new iPhone 13 Pro Max running iOS 17, with PUBG Mobile version 2.8.0 installed. The device was set to the default “Performance Mode” (max 120 Hz refresh). No background apps were running, Wi‑Fi was on a stable 5 GHz network, and the battery was at 100 %.

We captured three typical in‑game scenarios:

1. Open field with a distant plane – low clutter.
2. Urban match with multiple buildings – medium complexity.
3. Nighttime “sprint‑and‑shoot” map – high visual effects.

Each scenario was recorded for 60 seconds, and the average FPS was logged using the built‑in PUBG performance overlay.

Raw FPS Numbers

The iPhone 13 Pro Max consistently hovered around the 120‑FPS ceiling when the ProMotion display was active, but realistic gameplay rarely stays at that peak.

• Open field: 115 FPS average, with occasional spikes up to 119 FPS.
• Urban map: 103 FPS average, dips to 95 FPS during intense firefights.
• Night sprint map: 96 FPS average, brief drops to the low 80s when explosions lit up the screen.

Even the lowest readings stayed above 80 FPS, meaning the experience feels fluid on the 120‑Hz panel.

What Affects the Frame Rate

Graphics Settings

Turning on “Ultra Graphics” pushes textures and shadows higher, shaving off roughly 10‑12 FPS across the board. The “Low” preset, by contrast, can add a modest 5‑7 FPS, but the visual quality drops noticeably.

Thermal Throttling

After about 20‑30 minutes of continuous play, the chip starts to warm. The iPhone’s thermal management will gently throttle the CPU/GPU, trimming FPS by 3‑5 % to protect hardware.

Battery Saver Mode

Enabling iOS’s Battery Saver clamps the maximum refresh rate to 60 Hz, instantly halving the peak FPS. Gameplay remains smooth, but you lose the buttery feel of 120 Hz.

Tips to Optimize PUBG on iPhone 13 Pro Max

• Stick to the “Balanced” graphics preset; it preserves visual fidelity while keeping FPS in the high‑90s.
• Turn off “Dynamic Shadows” and “Ambient Occlusion” – the performance gain is measurable without a huge aesthetic hit.
• Keep the device out of direct sunlight; lower ambient temperature reduces throttling.
• Close background apps and disable “Background App Refresh” to free up RAM.
• Consider a quick “Airplane Mode + Wi‑Fi” toggle before a long session; it can clear lingering network buffers that sometimes cause frame hiccups.

Bottom Line

The iPhone 13 Pro Max delivers a consistently high frame rate in PUBG Mobile, comfortably above the 60‑FPS threshold most players consider the sweet spot. Even in the most demanding maps, it stays in the mid‑90s, thanks to the A15 Bionic and the ProMotion display. Simple tweaks—like choosing the right graphics preset and managing heat—can push those numbers even higher. If you value a fluid, responsive shooter experience without sacrificing visual polish, the 13 Pro Max remains a solid choice for PUBG enthusiasts.
