This Is the First Feature I Turn Off on Every New Samsung and Motorola Phone

Why It Matters

Virtual memory can slow budget smartphones and wear out storage, so disabling it improves performance and device longevity. The insight is crucial for consumers and manufacturers aiming for optimal Android experiences.

Key Takeaways

• Virtual RAM uses slow storage, reducing performance.
• Flagship phones already have ample physical RAM.
• Budget phones' storage too slow for effective swap.
• Android manages memory efficiently without virtual RAM.
• Disabling RAM Plus/Boost often speeds up devices.

Pulse Analysis

Virtual memory on Android phones works like a computer’s swap file, using a portion of internal storage to extend RAM. Samsung’s RAM Plus and Motorola’s RAM Boost automatically allocate this space, but storage media such as UFS 2.2 or eMMC are far slower than LPDDR5X RAM. When the system shuffles data between RAM and storage, latency spikes, leading to noticeable lag, especially on devices with modest specifications. The performance gap widens as newer flagships adopt ultra‑fast UFS 4.0 and LPDDR5X, narrowing the storage‑memory divide, yet even they possess enough physical RAM to render virtual extensions unnecessary.

Budget smartphones illustrate the downside of virtual RAM. A device like the Moto G 2026, with 4 GB RAM and 128 GB UFS 2.2, suffers when swap memory is enabled because the storage cannot keep pace with RAM demands. Android, however, is engineered to manage limited memory intelligently; Android 15 requires 4 GB RAM, while Android 16 steps up to 6 GB, and Android Go runs on as little as 2 GB. The OS predicts app usage patterns, retaining active processes in RAM and discarding idle ones, eliminating the need for a slower, wear‑inducing swap layer.

For users, disabling RAM Plus or RAM Boost is a quick win. On Samsung devices, the toggle resides under Settings → Device care → Memory → RAM Plus; Motorola places it in Settings → System → Performance → RAM Boost. After a reboot, the phone relies solely on physical memory, often delivering snappier app launches and extending storage lifespan by reducing write cycles. As manufacturers continue to push higher‑speed storage and larger RAM pools, the relevance of virtual memory diminishes, making its deactivation a sensible default for most Android users.
