Introduction to PUBG Mobile Performance on iPhone Pro Models
Understanding 120 FPS and Thermal Throttling Basics
Ever wonder why PUBG Mobile's 120 FPS feels like a game-changer on the iPhone 15 Pro/Pro Max, iPhone 13 Pro/Pro Max, or iPhone 14 Pro/Pro Max? It's all thanks to the 3.2 update, but you gotta stick to Smooth graphics to make it work. Pick 120 FPS without any fixes, and you'll tank below 90 FPS—iOS just chokes on rendering at 120 Hz. Then there's thermal throttling: the A17 Pro GPU heats up under load, and once temps climb too high, FPS plummets with lag spikes. Keep an eye on in-game indicators or head to Settings > Battery to track it. Aim for 90+ FPS steady, and keep things from getting too toasty.
Why iPhone 15/16 Pro Excels in Mobile Gaming
What sets the iPhone 15 Pro and 16 Pro Max apart in the mobile gaming arena? That powerhouse A17 Pro chip, paired with 120 Hz ProMotion displays and smarter heat sinks, lets them push 120 FPS way longer than older rigs. The 4441 mAh battery and 8 GB RAM hold the line above 90 FPS on Smooth graphics, leaning on the Metal API for efficient power handling. Sure, the 15 Pro demands a few extra tweaks compared to the 16 Pro Max's beefed-up cooling—but both shine. Benchmarks on iOS 18? No throttling in 20-30 minute matches once you've dialed everything in.
Close out background apps to free up all that RAM before you jump in.
Hit up the latest iOS update through Settings > General > Software Update—bug fixes are a lifesaver.
Reboot: Settings > General > Shut Down, then fire it back up.
(As an editor who's spent way too many hours tweaking these beasts, I'd say the 16 Pro Max feels like it was built for this—less fuss, more flow.)
Optimal Graphics and Frame Rate Settings
Step-by-Step Guide to Enable 120 FPS
Getting 120 FPS rolling in PUBG Mobile post-3.2 update? It's straightforward on iPhone 15/16 Pro—just grab the update from the App Store first. Set graphics to Smooth and frame rate to Ultra Extreme, but heads up: without workarounds, you'll dip below 90 FPS thanks to iOS quirks. On my iPhone 15 Pro with iOS 18, it starts at 60-90 FPS until you fix it. These hacks unlock true 120 Hz rendering.
Here's how to nail it:
Fire up PUBG Mobile and dive into Settings > Graphics & Audio.
Crank Graphics to Smooth.
Pick Frame Rate: Ultra Extreme and slide that FPS bar to 120.
Kick off screen recording right after (leave it running in-game) or flip the Limit Frame Rate toggle in Settings > Accessibility > Motion—enter and exit the game, then shut it off.
Kill motion blur and shadows for zero stutter.
Recommended Resolution and Style Settings
Smooth graphics are your best bet for 120 FPS—they ease up on the GPU and cut down on heat. Ditch anti-aliasing to keep things cooler. Fire up ProMotion on those 120 Hz screens for silky aiming, and cap frames at 120 to sync with the hardware. Tests on the iPhone 14 Pro Max back this: rock-solid 120 FPS after the toggles, no ban worries. Dropping resolution? It stalls throttling quicker, especially in steamy weather.
Go with a 4-Finger Claw layout to handle high FPS like a pro.
Tweak in-game resolution to balanced—saves battery without sacrificing much.
Hit the training ground to test; make sure no dips sneak in.

Preventing Thermal Throttling: Core Strategies
Device Cooling Techniques During Gameplay
Pushing high FPS ramps up the A17 Pro's power draw, inviting throttling if you're not careful. Skip charging mid-game—it just piles on heat and risks hardware wear. The iPhone 16 Pro Max's heat sink keeps 120 FPS humming at 90+ for long hauls, mimicking vapor chamber cooling. Without breaks, overheating kicks in after 15 minutes, tanking FPS below 90 and messing with touch response.
Try these:
Ditch the phone case and steer clear of direct sun.
Pause for 5-10 minutes every 20-30.
Grab cooling grips or pads for marathons; drop brightness to 50% from Control Center.
Bail if it starts feeling scorching.
iOS System Optimizations for Heat Management
Low Power Mode? Turn it off in Settings > Battery—it caps your CPU when you need it most. Shut down Background App Refresh in Settings > General to sip less juice. Aim for 80% free storage (say, 100+ GB on a 128 GB model) by nuking big files in Settings > General > iPhone Storage. Clearing 17 GB—like 4.6 GB of videos—speeds up animations. Flip Reduce Motion in Settings > Accessibility > Motion to lighten GPU load from fancy parallax effects.
Kill Bluetooth if it's idle; stick to Cellular Data over Wi-Fi when possible.
Trigger implicit Game Mode by closing apps and disabling refresh.
Refresh PUBG's cache in-game or via storage tools.
In-Game Sensitivity and Control Tweaks
Best Sensitivity for Smooth 120 FPS Aiming
At 120 FPS, nailing sensitivity is key—try Camera Sensitivity (No Scope) at 130%, ADS (Red Dot) at 50%, and Gyroscope (No Scope) at 300% to tame recoil and track foes effortlessly. For 2x scope, gyro at 270%; 4x at 160% keeps mid-range shots dialed without overcorrecting. These settings crush close-quarters chaos and long-range sniping on iPhone Pro models—honed in training for that muscle memory.
Steps to set it:
Head to Settings > Sensitivity and tweak by zoom: ramp up for no-scope/red dot, ease off for 6x/8x.
Activate gyroscope for tilt aiming.
Drill crouch-fire in the training ground to master hitboxes.
Gyroscope and HUD Customization
Tailor your HUD to a 4-Finger Claw setup for juggling controls at high FPS; bump overall sensitivity by 100% for reliable feel. Crank gyro higher for CQC to dodge heat-induced input lag. Fine-tune tilt in PUBG Labs for better recoil handling.
Layout for thumb and index finger dominance.
Disable auto-lock mid-game.
Dial it in via PUBG Labs for recoil mastery.
(From my playtests, gyro at these levels turns the iPhone into a precision tool—feels almost console-like.)
iPhone-Specific Hardware Considerations
