Fire up 120 FPS in PUBG Mobile 3.2+ (enhanced 3.5 Jan 2025; 4.0 Sep 11 2025; 4.1 Nov 6 2025) and slash input lag by 50% (down to 8.3ms frame delivery). You'll snag 15-20% better recoil control too. Snapdragon 8 Gen 2/3 beasts average 116-120 FPS with 98-99% consistency on Smooth + Ultra Extreme. These steps deliver 118+ FPS—no root required.
Why Chase 120 FPS in PUBG Mobile?
Picture this: 120 FPS shaves 8-16ms off input lag compared to 60 FPS. Animations pop 33% smoother, tracking sharpens by 12-18%. Esports pros demand 98.5-99% frame consistency—Smooth mode slashes polygons by 40% and eases GPU load 10-15% versus HDR (which guzzles 68% GPU at a 60 FPS cap).
Test it yourself in Training Ground: 10 minutes of straight gunfights. Aim for 118+ FPS from the jump, no dips in vehicles or final circles.
- Graphics > Show FPS.
- Log three full matches: early, mid, late game.
Low-End Devices? Here's the Real Talk
Snapdragon 870/860 or Galaxy A54/A55 hold 90 FPS for 7.5 hours easy, but 120 FPS? Expect drops and +40-60% battery drain. Smart fallback: Smooth + Extreme for 15-30 FPS bumps.
- Lock in 90 FPS if it's shaky; retest after 4.1 drops.

Gear Check: What Your Device Needs for 120 FPS
Snapdragon 8+ Gen 1, Dimensity 9000, A17 Pro chips with 8GB+ LPDDR5X RAM, UFS 4.0 storage, and 120Hz+ AMOLED (ideally 240Hz+ touch). Version 3.5 trims lag by 50%—game-changer.
Minimum Specs That Actually Deliver
RedMagic 9 clocks 120.8 FPS (0.2ms deviation, under 45°C); ROG Phone 8 hits 118.2 FPS (99.2% consistency). Mid-rangers like Mi 11+, Redmi Note 13, K50, POCO F3/X3 Pro (SD870) with 5000mAh+ batteries hang tough.
- Verify 120Hz in your display settings.
- Grab PUBG 4.1 (Nov 6 2025, 07:00 UTC).
Chipsets That Support It (Snapdragon, Helio, and Beyond)
Android stars: Galaxy S24/S23 Ultra, OnePlus 12/11, Pixel 8 Pro, Xiaomi 14 Pro, ROG Phone 8/7/6, iQOO 12, RedMagic 9 Pro. iOS: iPhone 16/15/14/13 Pro/Max, iPad Pro 2020+ (M1/M2/M4). Even Snapdragon 855+ unlocks 90-120 FPS in 4.1.
RAM and OS Sweet Spots
8GB+ RAM, Android 11+, iOS 17+; keep 4GB free RAM, 20GB+ storage. In Developer Options, cap backgrounds at 3-4 apps. (Pro tip from the edit desk: This alone stabilizes late-game frenzy.)

Troubleshooting: Fix the Hiccups
Clear cache weekly (fixes 85% of stutters), update firmware, reinstall if needed. Overheating past 42°C? Ditch the case, chill at 21-24°C AC, take 30-45min breaks (+15-20°C spikes tank FPS).
Crashes and Black Screens?
- Disable battery saver/optimization; nuke backgrounds.
- iOS: Latest iOS, tweak Accessibility; Android: Whitelist in Developer settings.
- Play unplugged (+6-10°C cooler).
Beat the Heat
External fans drop 10-15°C; stay under 48°C for 40-60min sessions. 5GHz WiFi, under 60ms ping. Quick checklist: 120Hz on, restart post-update, Training test.
