BGMI 4.2 Update Unlocks 120 FPS on iPhone 17: Complete Guide to Enable It

Battlegrounds Mobile India (BGMI) players with iPhone 17 rejoice! The freshly rolled-out 4.2 update, themed around "Primewood Genesis," introduces native 120 FPS support exclusively for Apple's latest base model smartphone.

This upgrade leverages the iPhone 17's new 6.3-inch Super Retina XDR display with ProMotion technology, delivering up to 120Hz refresh rates for buttery-smooth gameplay that's a game-changer in fast-paced battle royales.

Why 120 FPS Matters in BGMI

Jumping from 90 FPS (or lower on previous iPhones) to 120 FPS means noticeably reduced motion blur, quicker enemy tracking, and enhanced responsiveness during intense firefights, hot drops, and TDM matches. Early tests confirm "super smooth" performance in Team Deathmatch (TDM), with FPS meters hitting 119.98 consistently.

However, expect some trade-offs: the iPhone 17 heats up quickly under load, and battery drain accelerates in extended sessions.

The update also packs other goodies like a new Primewood Genesis mode, weapon balances, Metro Royale enhancements, and improved graphics options across devices.

Device Requirements

• iPhone 17 (base model; Pro variants may follow in future patches)
• BGMI version 4.2.0 or later
• Latest iOS update (iOS 19+ recommended for optimal stability)
• At least 4GB free storage for the update

Note: 120 FPS is currently in beta and labeled "Ultra Extreme." Krafton warns of potential overheating, choppy gameplay, crashes, or restarts - proceed with caution!

Step-by-Step: How to Enable 120 FPS in BGMI 4.2 on iPhone 17

Enabling it is straightforward via in-game settings. Here's how:

1. Update BGMI: Open the App Store, search for "BGMI," and tap Update if 4.2 is available. The rollout started January 15, 2026, for Android, with iOS following shortly after.
2. Launch the Game: Open BGMI and log in to ensure everything loads.
3. Access Settings: Tap the gear icon (Settings) in the top-right corner of the lobby.
4. Go to Graphics: Select the Graphics tab at the bottom.
5. Choose Your Graphics Style: Pick a preset like Combat, Balanced, or Smooth for best results (avoid maxed-out Ultra HD initially to prevent instability).
6. Select Frame Rate: Scroll to Frame Rate and choose Ultra Extreme (120 FPS). A warning popup will appear - tap Confirm to proceed.
7. Fine-Tune (Optional):

7. Apply and Test: Hit Apply, jump into a TDM or Classic match, and monitor your FPS via the in-game overlay (enable in Settings → Gameplay).

If the option doesn't appear, force-close the app, restart your iPhone, or wait for server-side rollout.

Performance Tips and Caveats

• Heating Management: Play in a cool environment; use a cooling pad for long sessions. Tests show quick warm-up during TDM.
• Battery Life: Expect 20-30% faster drain - lower to 90 FPS (Extreme) for marathons.
• Stability: Beta feature, so report bugs via in-game feedback. Classic mode hotdrop tests are ongoing, with promising early results.
• Android Users: Some 90 FPS devices got 120 FPS too, but iPhone 17 is confirmed.

What's Next?

Krafton is expanding 120 FPS to more devices post-beta. Stay tuned for full Classic/Erangel optimizations and potential iPhone 17 Pro Max support. Drop your FPS test results in the comments!
