Are you noticing lag or slow response on your Galaxy device? By changing a few important Samsung settings to improve performance, you can instantly boost speed and make your phone feel brand new again. These performance-enhancing tweaks work on all Samsung models and require no third-party apps.
The good news?
You can instantly speed up your Samsung phone by changing a few powerful settings that Samsung hides deep inside One UI.
In this expert guide, we’ll walk through the 10 most effective Samsung settings that will dramatically improve speed, responsiveness, multitasking, and battery efficiency—without installing any third-party apps.
🔧 1. Disable or Reduce Animations (Instant Speed Boost)
Samsung’s smooth animations look beautiful but consume RAM and CPU resources. Reducing them instantly makes your phone feel snappier.
How to Turn Off Animations
- Go to Settings → About Phone
- Tap Software Information
- Tap Build Number 7 times to enable Developer Mode
- Go back → open Developer Options
- Change all three settings:
- Window animation scale: 0.5x or Off
- Transition animation scale: 0.5x or Off
- Animator duration scale: 0.5x or Off
Why It Boosts Speed
Samsung devices load UI elements faster because the phone no longer waits to “play” animation frames.
🧠 2. Optimize RAM Plus for Real Performance
RAM Plus uses your storage as virtual RAM, but many users set it too high, causing unnecessary I/O stress.
Best Setting:
2GB or 4GB (Recommended)
How to Change It:
Settings → Battery & Device Care → Memory → RAM Plus → Choose value
Why It Matters
- Too little RAM Plus = weak multitasking
- Too much RAM Plus = slower file system → lag
This balanced value gives the best performance-to-storage ratio.
⛔ 3. Limit Background Running Apps
Background apps constantly consume battery, CPU, and RAM.
How to Stop It
Settings → Battery & Device Care → Auto Optimization →
✔ Close apps in background
✔ Auto-optimize daily
What This Improves
- Faster app switching
- Longer battery
- Less heat
📦 4. Remove Samsung Bloatware Safely
Samsung phones ship with dozens of apps you might never open. These apps run services in the background, affecting performance.
Safely Disable These (Optional)
- Samsung Free

Benefits

🧹 6. Clear System Cache & App Cache Regularly
Caches speed things up, but an old or bloated cache causes UI lag.

🌙 8. Turn On Lite Mode (Easy Mode) for Older Phones
If you use an older Galaxy phone (A-series, M-series), the UI can feel heavy.
Turn On Easy Mode
Settings → Display → Easy Mode
Benefits

- Removes animations
- Simple, minimal interface
🧱 9. Remove Home Screen Widgets & Live Wallpapers
Widgets refresh data every few minutes and drain RAM.
