RAM Plus

[stevenf123]

Hello.

I've read varying opinions on RAM Plus, and would like to know if enabling it or disabling it is the best choice.

I have a 25 Plus 12gb phone, and RAM Plus now has the option of using 12gb, but I'm unsure as to do this.

I've disabled RAM Plus currently, and as of this morning, I have 2.3GB available, which is as low as I've encountered.

Even after cleaning the memory, it only goes as high as 6GB, and before ONE UI 8 Beta, it used to be between 7.5GB and 8GB.

Thank you.

Ram plus uses your phones storage for extra memory so weather having it on or off really falls down to the individual.

For me I currently use the S25 Ultra with 1TB of storage and 12GB of ram. I have ram plus enabled because I know i won't need 1TB so ram plus uses the some of that 1TB storage as extra memory. Atleast thats how I was told it works.

I have mind turned on. Just makes me feel better.

Hello @stevenf123,

I encourage you to try it yourself as it is a matter of individual choice 😊

I've turned mine on.
RAM usage seems really high on One UI 8.
Phone started stuttering badly earlier on Facebook.
Checked device care and I had less that 1GB free RAM left.

950MB was being used by Facebook.

I leave ram plus set at default. One ui 8beta does seem to use more ram but as long as you still have free ram it's not a problem.

I've been using the 12GB ram plus and I've had no ram related issues.

Disabling RAM Plus on 12GB variant is a performance optimisation, not a downgrade.

RAM Plus uses part of your UFS storage as virtual memory (zRAM-like swap). While it can help on lower-end devices, it’s orders of magnitude slower than LPDDR5X RAM:

RAM latency: ~10–30ns
UFS 4.0 storage latency: ~100μs+ (thousands of times slower)
RAM bandwidth: ~8.5GB/s vs UFS: ~3–4GB/s (sequential, best-case)

On a 12GB phone, physical RAM is rarely saturated, and Android is designed to cache aggressively. Seeing 2–3GB “free” is normal, unused RAM is wasted RAM in Linux-based systems.

RAM Plus introduces extra I/O overhead, increased thermal output, and wear on the storage all for no real-world gain on high-RAM devices. In fact, it can cause slower app switching as apps get paged out unnecessarily.

In testing, disabling RAM Plus leads to:

Faster multitasking performance Lower sustained temperatures Better battery efficiency
Reduced app reloads when switching

TL;DR: On 12GB RAM phones, RAM Plus doesn’t help; it hinders. Let the device use actual RAM. RAM Plus is a tool for devices with 6–8GB, not flagships.
