[Q] RAM question

Such a cool Phone but why has it only 512 RAM? My next phone schould last for ~3 years and i doubt that 512MB ram will be enough
What are your opinions on this? Are 512MB enough today or should i look after another Phone with 1GB RAM??
On which Apps could 512 MB RAM have a negatively impact?
Greetz und Thanks

My Question about the RAM Issue:
- Can Swapper2 be used ?
- Can u use Swapper2 on many Applications (does it make sense)?
Thanks for your help!

512MB is enough..

Yeah i think it too, that first it will be enough.
But i'm not buying a new Mobile Phone every year. And i don't believe if it it's enough in 1 or 2 years. So it would be great it swapper works or sth like this.
Nxt Question:
How much RAM do i effectively got. Cause i read that u have 512 MB minus 128 MB for the GPU minus 200 for the OS.
So there is perhaps 200 free for the apps?
Is this right ?

Ram in 2X:

Root it, remove a few of the preinstalled apps or exchange them against some with lower memory usage or use a custom rom and you will even have more ram available. I think 512 MB will be enough...

You should also be able to lower the ram reserved for the gpu. It should be possible to free up to 100mb if you dont play many games otherwise up to 64mb.

According to some reviews it seems that the Optimus 2X reserves 128MB for the GPU. This would mean you only get a total of 512 - 128 = 384MB of RAM for Program Memory.
That's at least one thing HTC did well on their latest devices. Devices like the Incredible S and the Desire S ship with 768MB of RAM.
I think the RAM in the 2X is enough to work with the device but it sure ain't a lot.

Bill Gaits Believed that 640K RAM will be enough few years ago
But Yes so far (i am using android for 2 years now) it proved - 512MB are enough!
And if there only 2-3 devices with bigger RAM - so developers will stick with 512 for a while.

my opinion is that 512 mb is good for this time. i have a galaxy s with a custom Rom and i have 339 mb of ram and the device.work fine.
i see that i will use approx 20 mb of extra ram and(galaxy vs LG) and also you have a dual core.processor that optimize some operation.
well... i think that for this moment and for approx 1 year 512mb of ram will be a good choose!

That's not a question...

Got a o2x and can confirm you got 381mb of free ram for apps... that makes 128mb dedicated for gpu. Got around 110 mb free at the moment, and I have a lot of Apps running. When I get custom rom, some of the ram will be cleared, when removing unnecessary apps. I got adw launcher running on top of stock ui

Perhaps 512MB dedicated to system RAM only

500 MB is probably being used by the GPU

1.5GB of RAM is available to these running applications. If you navigate to Settings > About> Hardware Information the 2GB value will be seen. 0.5 GB is dedicated to ensure the device software runs smoothly.

All thats says is that its "used by something else". The question is what.
And judging from how its worded it seems like its referring to the 0.5 GB going to the GPU.

It actually says its used to make things run smoother. I don't know how much you know about hardware, but GPUs have their own ram. A phone GPU wouldn't share system ram. Ram is used to hold temporary files such as an open app. As soon as that app is force closed/force stopped then that information is flushed from ram. Think of it like having a dual core processor. One core of ram keeps the currently running app or apps in its memory. Meanwhile, the other 512 mb core holds just system software. That way your apps are never making your Sense/ROM/etc slow. Its pretty smart.

Most devices do this. The reserved RAM is to store critical processes like the dialer, base Android process, and other related things.

The operating system requires ram to actually run, its no different than a pc, total ram is not the same as available ram.

I'm 99.999% sure that the ram you are not seeing is system/hardware reserved memory that would not report as available memory.

Most phone GPU's dont have dedicated memory and would in fact share system memory much like most laptops graphics cards.
Pretty sure if you cat /proc/iomem you'll see the addresses of the ram that has been reserved by the system.

I echo this. Basically it is just all a matter of how the system is reporting the memory. On my Note II, it shows almost all of the 2GB, on my HTC One, it excludes the system reserved memory.

[Q] Only 23GB "Total Space" on 32GB Nexus 6 right out of the box?

Anyone else notice that right out of the box you only have 23GB of usable storage on the 32GB variant?
I know that you'll never get the full storage amount due to the ROM taking up space. However, on both my Nexus 4 and Nexus 5, with 16GB total space, I had at least 12GB available right out of the box. So I'm used to having ~4GB of unusable space. But 9GB of space taken right off the bat for a pure Android device with no bloatware does not seem right to me.
Anyone know why this might be?

Starting from lollipop, the phone uses art run time. Art takes up more space in the internal storage, it's one of the tradeoffs when compared to dalvik.
And no you can't change back to dalvik on lollipop.

Good to know. Thanks!
I guess this is just one more reason many should opt for the 64GB.

Now that I'm on a computer, I can elaborate my point in more detail,
Android 4.4 KitKat, at least on the Nexus 5, includes a new runtime call “Android runtime”, ART. Though it’s not a very creative name, it is pretty creative in what it does. Unlike JIT, which must compile every app whenever it’s loaded, ART works on a concept called ahead-of-time (AOT) compilation. With ART, when you download and install an app it automatically pre-compiles. This takes up more space on your device and takes longer to initially install when compared to Dalvik. However, apps launch quicker and are arguably faster when run using ART rather than Dalvik. What’s more, since less time is required to run apps, your processor doesn’t get worked as hard and your battery life may benefit as a result.

Do note that the above is from Kit Kat's ART which can be different from Lollipop's ART (improved and more finalized)

This isn't much difference to the 32gb Nexus 5 which has 26gb.

That's weird -did you get a carrier model vs an unlocked one from the playstore?
People were posting 25GB free last week for the 32GB....

I have 54 GB free "total space" on mine.

I got the the 32GB

You have a 64gb. System overhead seems to be about the same as OP's.

OP, were any carrier apps loaded on during setup? If so, remove and get that space back.

For this phone, only AT&T gets carrier apps pre-loaded. To be honest, a lot of the Google Applications are bloatware.
Bloatware examples are: Fit, Earth, Books, Movies, Google+, etc.

I agree with you, but to the OP's issue, he may regain some of his space by removing them, it's been said that you can remove those said carrier apps. As to the others, they may be removable, or one may need root if they are loaded just in /system. Thing is the OP hasn't stated if he got a GP or moto phone, or one from a carrier to begin with.

Initially I was disappointed with the seemingly low space, but you have to keep in mind that a good chunk of that 32GB is lost to formatting (I'd estimate around 10%-15%). The rest is used by the operating system. So 24GB of free space is very plausible on a 32GB device.

Correct I was posting that as a comparison seeing that mine has about the same amount of space taken up.

Antutu Test Results are different between 512GB and 128GB

So, Me and my friend decided to give a test run. I know conditions were different, One was offline and the other was on Dual VoLTE.
But, This much of a gap?

Are you sure the 512 wasn't in power save mode? Battery was at 15% compared to 87% on the 128.

Wow, that's a huge win for the 512, if true. Is that not a real-world performance type of difference, in your estimation? I'm really struggling with the decision of 128 vs. 512. I have a 256GB SD card and don't even have 50GB used up on my Note8 internal... So I'm thinking I should stick with the 128 and save the $250. Unless there's actually a performance difference, but I'm not sure 8GB can do much at this stage. I don't know!

In theory then the Snap 128 should beat the snap Exynos then? One thing I've learned in the past couple of years is benchmarks are essentially for bragging rights, there is no real world impact on an Antutu score from 250 to 300k. Not unless you are measuring apps opening in milliseconds and want to claim because your phone opened said app .00001 ms faster you win. I've never had any type of problems in real world use of the Note 8. I suspect it stays the same with the 9.

Perhaps Samsung is using slower memory chips in the 512gb version? I remember awhile back some phones of the exact same model were unperforming because they were using slower memory chips in some of them.

Should I wait for 6/128 version or just go with the 4/64 one?

From a technical standpoint, I don't think 2 gigs of extra RAM is gonna give the phone a 20% boost in performance, but is 64 gigs enough keeping in mind no expandable storage?
I'm coming from Redmi 2 Prime with 16gig internal, but I have a 32gig SD which is almost filled all the times.
So what do you say - should i wait for the 128gigs to come?
Also, for my Indian friends, can anybody guess the price of 128gigs? I'm thinking under 20k probably.

no need to guess the 6/128 model price, it's already listed for €283.78 at gearbest but I personally think there's no huge difference in performance as android 9 will use ~2,5GB RAM and pixel 3 XL will even come with 4GB, right? howevery finally it depends on usage, for playing games Mi A2 might not be a top deal, I read it's getting hot. for my daily usage - web, email, fotos! - the 4GB model is perfect.

I own the 6/128 model while my brother has the 4/64. As far as I can tell, it rarely makes a difference, such as when engaged in many apps (We've tried with Snapchat, Facebook, Whatsapp, Camera, and Google Photos. It was a minimal difference but I have to say that the extra storage with cloud functionality is awesome. I wonder if I can root this Android One model of the 6X.
It's not getting hot in my opinion, unless it's charging. It goes well beyond 50 degrees, which is kinda toasty. I have tested the thermal issue as such: Pokemon GO with max brightness and 4K-30FPS max brightness. The phone got a bit excited at start but in the end it managed to keep itself from overheating without reducing performance that much. As for the camera... I am a bit disappointed since I was expecting something a bit better than the A1 but it seems to be pretty much the exact same. I can do some sample photos of everything if anyone is really interested.

As it's been for a long time (computers, laptops, etc), the extra ram won't increase performance. It ** Will ** perform better if you open many many apps at the same time.
Do you do that? If it's necessary for you to, then wait. If not, then don't.
The extra storage is soooo subjective. I don't create or use huge files. If I did create huge video files (as an example), I'd use wifi and upload to some cloud storage, when possible. But, some people may be doing multiple vids in a short time and don't have the opportunity to upload... so for them it may be worth getting the 128.
It's not really a mystery, if you have ever run into storage limits (say with a 64), then get the 128. If you haven't before, you probably won't now.
I too wish the Mi A2 had an expansion slot, it would be nice. But is it a necessity? Not for me it's not. I could use it for years and never have it affect me.

If you can wait then get the 6/128. If you need the phone right now then buy the 4/64.
It all depends on what your requirements are.
