All Devices That Can Handle 120 FPS

First things first: not every phone can run Once Human Mobile at 120 FPS. You’ll need a powerful device with top-tier specs. Phones with these processors are your best bet:

  • Qualcomm Snapdragon 8 Gen3 or Gen2
  • MediaTek Dimensity 9300 or 9200+
  • Apple A17 Pro (found in iPhone 15 Pro and Pro Max)

Aside from a strong chipset, your device also needs a screen that supports a 120Hz refresh rate. Without that, even if your phone pushes 120 FPS, you won’t actually see the full benefit.

Setting Up Once Human Mobile for High FPS

Once you have a capable device, it’s time to fine-tune your settings. Here’s what you should adjust:

  • Graphics Quality: Stick to ‘Medium’ for a safer, smoother experience. You can try ‘High’ if your phone can handle it without overheating.
  • Frame Rate Limit: Always set it to 120 FPS if the option is available.
  • V-Sync: Turn it off. It can add input delay and limit your frames unnecessarily.
  • Close Background Apps: Free up memory and processing power by shutting down unused apps before you play.
  • Disable Battery Saver: Battery-saving features often slow down your phone’s performance. Make sure they’re off while gaming.

These tweaks can make a big difference, especially during intense battles where frame drops can cost you the match.

Boosting Performance with Extra Tools

If you’re still seeing frame drops or lag, there’s another option: use a performance booster app. One good example is LagoFast Mobile Booster. It helps stabilize your connection and free up system resources. Here’s how to use it:

  1. Download LagoFast Mobile Booster from Google Play or the App Store.
  2. Open the app and search for “Once Human.”
  3. Pick a server and route that’s closest to you.
  4. Tap ‘Boost’ and then launch the game.

It’s a simple way to squeeze out a few extra frames and enjoy a smoother experience.


Running Once Human Mobile at 120 FPS isn’t just about having the newest phone; it’s also about setting up your device the right way. With a strong processor, a fast refresh screen, the right settings, and maybe a little help from a booster app, you can experience the game at its very best. Once you do, surviving the world of Once Human will feel more immersive than ever.
