Samsung Galaxy S20–S25: RAM Plus Support, Performance Comparison, and Setup Guide

🌟 Complete Comparison of the Samsung Galaxy S Series (S20–S25): RAM Plus Support, Performance, and How to Enable It

Introduction

The Samsung Galaxy S Series is Samsung’s flagship smartphone lineup that continues to evolve from generation to generation. In addition to improvements in cameras, chipsets, and displays, one increasingly important aspect is RAM management and multitasking, especially since Samsung introduced the RAM Plus (Extend RAM) feature through One UI.

However, not all Galaxy S Series models support RAM Plus in the same way. Some early models did not include it at launch, others received it through software updates, while newer generations have optimized it from the start.

This article covers:

• What RAM Plus is and its functions
• Its advantages and disadvantages
• How to enable RAM Plus
• A complete comparison of the Samsung Galaxy S20 to S25 (including Ultra, Plus, and FE variants)
• Explanations for models that do not support or only partially support RAM Plus

🧠 What Is RAM Plus (Extend RAM)?

RAM Plus is a feature from Samsung (One UI) that allows devices to use part of their internal storage as additional virtual RAM.

📌 Important points to understand:

• RAM Plus is not physical RAM
• RAM Plus uses storage (UFS) as temporary memory
• Its purpose is to assist the system when physical RAM is nearly full

RAM Plus helps maintain system stability, especially when multiple apps are running simultaneously.

⚙️ Functions of RAM Plus

RAM Plus is designed to:

• Keep applications active in the background
• Reduce app reloads when switching between apps
• Assist multitasking (split screen, floating windows)
• Stabilize overall One UI performance

📱 Its impact is most noticeable during:

• Daily multitasking
• Running social media and a web browser at the same time
• Light to medium productivity tasks

👍 Advantages of RAM Plus

✔ More stable multitasking
✔ Apps are less likely to close unexpectedly
✔ Helpful for devices with 8GB–12GB of RAM
✔ More optimized on newer One UI versions

⚠️ Disadvantages of RAM Plus

❌ Slower than physical RAM
❌ Not significant for heavy gaming performance
❌ Uses internal storage (very minimal wear)
❌ Can be less effective on older devices

📌 RAM Plus improves stability, not raw performance.
