FPS Check Tool for Browser Games

“Is your smartphone feeling slow?” “Are your game apps or browser games lagging?” On this page, you can easily check your device’s performance with FPS (Frames Per Second). Higher FPS means smoother gameplay and videos, while lower FPS can cause stuttering and lag. Before searching for recommended games, check your device’s performance first! No installation needed — measure with just one tap.

About the FPS Check Tool

This free tool allows you to quickly measure the processing speed (FPS) of your smartphone or PC when playing browser or game apps. FPS (frame rate) is a key indicator of game smoothness — the higher the number, the more comfortable the gameplay experience.

This page measures your device’s effective FPS and displays the comfort level.

Solutions When Your Phone is Slow or Laggy

When FPS (frames per second) is low or unstable, it is often due to memory overload, overheating, insufficient storage, or settings. Try the following steps in order from top to bottom.

① Quick Fix (1 minute)

  • Close unnecessary apps: Swipe unused apps away in the app switcher.
  • Restart your device: Resets memory usage, often making it smoother.
  • Unplug charging cable: High load while charging causes overheating, leading to FPS drops.
  • Temporarily turn off Low Power Mode: CPU/GPU performance may be restricted.
  • Remove phone case: Thick cases can trap heat; removing them may help.

FPS Guide: Stable 60fps = Smooth / 30–59fps = Can improve with settings / Below 29fps = Prioritize lightening and cooling

② Apps / OS (Update & Limit Background)

  • Keep apps and OS updated: Often includes bug fixes and optimizations.
  • Review background data/location: Turn off notifications, location, and auto-start for unnecessary apps.
  • Reduce widgets and resident tools: They consume memory, keep only essential ones.
Tips for iPhone
  • Settings → Battery → Low Power Mode: Recommended OFF during gaming.
  • Settings → General → iPhone Storage: Remove unused apps, enable offloading unused apps.
  • Settings → General → Software Update: Update to the latest iOS.
Tips for Android
  • Settings → Battery → Power Saving Mode: Recommended OFF during gaming.
  • Settings → Apps → Target App: Adjust background restrictions and auto-start.
  • Settings → System → System Update: Update to the latest OS.

③ Storage / Cache Cleanup

  • Maintain at least 15–20% free space: Move photos/videos to the cloud, uninstall unused apps.
  • Clear browser/app cache: Do it periodically if the device feels sluggish.

④ Overheating Measures (Major Cause of FPS Drop)

  • Avoid direct sunlight / hot environments: Especially outdoors in summer or inside cars.
  • Take breaks during long play sessions: Wait until the device cools down.
  • Place on ventilated surfaces: Avoid beds/sofas that trap heat.
  • Temporarily remove thick cases: They may hinder heat dissipation.

Warning: Do NOT put the phone in a fridge/freezer or apply ice packs directly — condensation can cause damage.

⑤ Game Settings Optimization

  • Graphics: Lower to Low–Medium (turn off shadows, reflections, depth of field, post-effects first).
  • Resolution/Rendering resolution: Lowering by one step greatly reduces load.
  • Frame rate cap: Choose 30/60/120fps depending on your device, prioritize stability.
  • Disable unnecessary overlays (recording/floating windows/notification banners).

⑥ Network Stabilization (For Online Games)

  • Prefer 5GHz Wi-Fi; move closer to the router if signal is weak.
  • Temporarily disable VPN/proxy: They may worsen latency.
  • Reduce devices on the same network: Avoid bandwidth competition.

⑦ Advanced (Android only)

  • Developer Options (at your own risk): Set animation scale to 0.5x or Off.
  • Enable manufacturer-provided Game Boost/Game Turbo.

FAQ

Q. Why does FPS suddenly drop?

Mainly due to overheating, which triggers thermal throttling. Cooling, taking breaks, or lowering graphics can help.

Q. Is it okay to use Low Power Mode?

It extends battery life, but limits performance during gaming. Recommended OFF. Take breaks during long sessions.

Q. How much storage space should I keep free?

Keep 15–20% free. When storage is full, read/write speed slows down, causing lag.

Q. Should I raise the frame rate cap?

If the device has headroom, yes, but it increases heat and power usage. Stability-focused: 60fps, or 30fps if needed.

Q. What if nothing improves?

Review resident apps, reinstall OS, or suspect device aging (battery/SoC). Consider upgrading if necessary.
