How to Fix Lag and Boost FPS in Android Games – 2025 Ultimate Guide

Mobile gaming is bigger than ever in 2025, but one problem still frustrates players across the world: LAG! Whether you play PUBG Mobile, Free Fire MAX, Call of Duty, or Genshin Impact, lag can ruin your gameplay, slow your reaction time, and make winning impossible.

Luckily, you can fix lag and increase FPS (frames per second) on your Android phone with a few smart tricks. In this article, we’ll show you 10 proven ways to boost your mobile gaming performance — especially helpful for users with 2GB, 3GB, or 4GB RAM devices.

⚙️ 1. Use a Game Booster App

Install a trusted Game Booster app like:

Game Booster 4x Faster
Gamers GLTool Pro
Xiaomi/Mi Game Turbo (in-built for Xiaomi users)

These apps help by:

Stopping background processes
Freeing up RAM and CPU power
Clearing cache instantly before launch

Tip: Always boost before starting your game session.

📱 2. Lower Graphics Settings in Game

It may be tempting to play in Ultra or HD, but for low and mid-end phones, this can cause lag spikes. Reduce:

Resolution: Set to Smooth
FPS: Set to Medium or High (never Extreme if your phone lags)
Shadow, Anti-Aliasing, Bloom: OFF

This instantly gives smoother gameplay without frame drops.

📦 3. Clear Storage Space (Keep 3–5GB Free)

Full storage = more lag.

To fix this:

Delete unused apps and games
Clear WhatsApp images/videos from gallery
Move photos to Google Drive or SD card

Try to always keep at least 3GB of free space for smooth gaming.

📶 4. Switch to Fast, Stable Internet

If you play online games, lag may be from a bad connection – not your phone.

Try these:

Use 4G/LTE or 5G only (avoid 3G)
Play near your WiFi router
Turn off auto updates and background sync
Use a gaming VPN for stable ping (e.g., UU Game Booster, Turbo VPN)

Ping Tip: Always test ping before starting ranked matches.

🧼 5. Disable Background Apps

Even if you close an app, it may still run in the background (Facebook, Instagram, TikTok, etc.).

Go to:

Settings → Apps → Running Services
Force stop unnecessary apps

You can also disable auto-sync and background data for better performance.

🌡️ 6. Keep Your Phone Cool

Overheating causes throttling, where your phone slows itself down to reduce temperature. Avoid this by:

Playing in a cool room or under a fan
Removing the phone cover while gaming
Taking 5-minute breaks every 30 minutes

Never charge and play at the same time — it heats the phone badly.

🔋 7. Turn Off Battery Saver & Power Saving Modes

Battery saver restricts CPU power and background data to save battery, but it reduces performance.

Before launching your game:

Turn off battery saver
Set power plan to "Performance" if available

This allows the processor to give full power to your game.

📶 8. Use Airplane Mode (Offline Games Only)

If you’re playing an offline game, switch on Airplane Mode to:

Disable all background network usage
Save battery and reduce heating

This works especially well for offline racing, fighting, and simulation games.

🧠 9. Developer Settings Tweaks

You can unlock developer options and change a few hidden settings:

Go to Settings → About Phone → Tap “Build Number” 7 times
Now go to Settings → Developer Options

Change:

Window animation scale: 0.5x
Transition animation scale: 0.5x
Animator duration scale: 0.5x or OFF
Enable “Force GPU Rendering”

Warning: Only change what’s shown here. Don’t tweak unknown options.

📤 10. Keep Your Game & Phone Updated

Developers constantly release updates that fix lag and optimize performance.

Update your game from Play Store
Install system updates (Android security + firmware)

Never use modded APKs – they can be buggy and laggy.

📌 Bonus: Best Lightweight Games for Low-End Phones (2025)

If your phone has 2GB–3GB RAM, try these lag-free games:

Free Fire MAX (Low Settings)
Battle Prime
Real Racing 3
Into the Dead 2
Shadow Fight 4

These games offer smooth performance even on older devices.

✅ Conclusion:

Lag can destroy the fun of gaming, but with the right tricks, you can easily reduce lag and boost FPS — even on low-end devices. Use a Game Booster, turn off battery saver, and adjust developer settings for the best results.
