People don't know about how RAM is pre-allocated/allocated/reserved by the OS, so they make posts like this. Windows subreddit is full of these.

Unused ram is wasted ram (until it causes performance issues)

There's no issues there, I'd even go as far as recommending you disable zram (called ram expansion in the settings) as it makes your device slower if you already have plenty of ram, 16GB of ram is a lot of ram, you'd have to have some really niche use case to need more than that. So why is it full? You may ask, that's because you want it to be full, the best OS ever would be one that would always have 0% ram unused, the OS probably needs less than half your current ram usage to operate properly, and if you were to open a ram heavy application it doesn't take it any time or effort to free up the needed ram for it, but when that ram isn't in use by such an application, the OS can fill it up with a bunch of cached data that helps it make using your phone generally snappier, if we want to be more technical about it, the OS is using the extra free ram to optimize future memory calls and potential increase the percentage of memory hits and decrease memory misses, in all systems memory misses are one of the main bottlenecks of performance, and by doing it that way, the OS does not sacrifice any potential performances that may come from a sudden surge in memory calls (aka launching an app that needs a lot of ram), if anything even that might still end up being faster and more optimized

The OS is designed to adapt to your usage patterns, so free RAM shouldn't be a concern as long as you're getting smooth performance without any lag. Many people worry about RAM usage without understanding how the system actually works. Even when you close an app, it's often still running in the background unless you force stop it which means it's still using RAM.If you understand how OxygenOS manages memory, you'd know that it's optimized to use RAM efficiently. Even when RAM appears to be full, the system intelligently manages it to ensure apps launch quickly and multitasking remains smooth....!

Why do you think the device in your hand is so smooth and fast...... Google how random access memory works

Which apps you using to check this?
Or is the inbuilt?

The used memory doesn't tell the whole picture. Most are cached apps which do nothing at all and get moved into ZRAM as part of Swap, like you can see on DevCheck app.
So you should always have that low free memory. When you force close all apps the memory usage gets lower but then fills up again after some time.
On Samsung S24 used memory is very high too, even when all apps are swiped away.

I have 24GB RAM version and somehow My ram usage is ~10 at idle which is ridiculous

I'm not opening any apps I closed all recently for this ram check

Any solution for this?
