Galaxy S6 exhibiting overzealous RAM management, report users

Galaxy S6 exhibiting overzealous RAM management, report users
The Galaxy S6 and S6 edge come with the latest cutthroat DDR4 RAM technology, and 3 GB of the good stuff at that, but when it comes to the actual RAM management, Samsung might have dropped the ball, judging from several forum threads and user reports.

In a nutshell, Galaxy S6 owners are reporting a very aggressive RAM management, to the point where apps get constantly shut down, and there's 200-400 MB of RAM left only at any given time. Granted, Android's RAM usage is made this way, and the system feels best when most of the available RAM is utilized, that is why task killers and RAM boosters are never a good idea, but still. 

The users have already reported this issue to Samsung, and there might be a software update in the future to bring on a more efficient RAM management - we can only imagine the app sprawling that will be happening on phones with Lollipop and 4 GB of RAM, of which there are already a few out there.

Can anyone please explain to me what in the universe is memory leak, is it fixed in android 5.1? Also, what is the real improvement in android from KitKat to lollipop other than material design?

On KK GSA4 had started from 600MB (toping 1GB) and with Lollipop begin with 1GB of RAM (toping 1.4GB) from 2GB installed. I remember Google telling us how Lollipop will smooth run on 512KB. Lollol

That's Samsung's fault (unless you are talking about the memory leak in some builds of Lollipop, which is Google's fault, but also Samsung's for not noticing/fixing it)

On my Nexus 5 (2GB ram)
Lollipop uses about 300MB
KitKat also used 300MB

On my brother's 2013 Moto G (1GB ram)
Lollipop uses about 200MB
KitKat used 250MB
Motorola's 5.0.2 build also didn't have any memory leaks

On my Moto X 2013 - 2GB ram, KitKat uses 420MB ram on cold boot. And device is freshly formatted since i intend to sell it.

if you saying that S6 using a lot cuz of lollipop memory leakage than you wrong. I had Note 4 and it was running Kitkat and every app use a lot more RAM than any other smartphone. so its basically Samsung TW or its own RAM management. I think its happens cuz of multi window feature and other multi tasking features on Samsung devices.

My note 4 usually has about 1.3 gigs of ram free at any given time. When I took back my s6 it usually only had 400 free. In all aspects note 4 is a better phone than the s6.

My HTC M9 can have easily 5 to 10 apps open at the same time and i switch between them with no loading at all everything is smooth as butter.

Samcrap Touchwiz is the problem here.

A memory leak is when the memory is allocated somewhere and not eventually released afterwards
So you have lots of memory being wasted

Most the OEMs fixed the 5.0 memory leaks in their builds of 5.0

5.1 from Google also fixed the 5.0 memory leaks as well

But Google introduced a new memory leak in 5.1
Some specific games cause system memory usage to increase by 100mb with each launch

No word on 5.1.1 yet
Will probably have 5.1's memory leak fix, since Google have found a fix for it according to their bug tracker
But we don't know if there's any new memory leaks in 5.1.1

70. bondosho (Posts: 14; Member since: 07 Nov 2011)


Unfortunately, the memory leak didn't get fixed until 5.1.1. I'm running CyanogenMod 12.1 on my Nexus 5, and it's wonderful.

Memory leak: when a program keeps on using more and more memory and nevers frees it up. The memory usage keeps on growing for that program and finally you have to restart the device/program because it is hogging all the memory. The memory leak on 5.0.1 is in the stock launcher and should be solved in 5.1 (hopefully(
There are several improvments in Lollipop, but as I don't know which ones interest you I let you the source:

That's what happens when vendors care more about benchmark scores than real UX. And Sammy is the king in that.

Sammy will fix this sooner or later.

But what bothers me is that the review sites don't bother running benchmarks again after such a major patching is done.

And I'm absolutely sure that ALL Sammy's phones perform much worse once such bugs(ehhh..... features) are gone.

93. marorun (Posts: 3369; Member since: 30 Mar 2015)


But they are quite fast to run benchmark again on the M9.

Well M9 benchmark may be bad compared to S6 but at least on mine i can open many apps at the same time and switch between them with no loading or app been closed..

So as usual in real life performance the HTC is better but thanks to a much much better marketing Samsung will sell more.

Android based OS are distributed by over 100 oem each bloated with custom implementations.

I have Oneplus One with Cyanogen OS 12 (5.0.2)...and it has no lag or memory leak issue. And then there is Oxygen OS (5.0.2) from Oneplus...even fast and smooth than Cyanogen OS 12.

Common thing between these two OS is they don't have custom UI like touchwiz or sense. Samsung slows down android with their touchwiz for no reason...it's now time, people should ask samsung to ditch touchwiz and embrace stock android ui.

i think it's time for some blind android fans to try other things like windowsphone. i'm using a 200$ lumia 920 for almost 2 years now n never experienced an app crash, bug, lag, random restart or these kind of sh!t. now talk to me about app gap, wow wp doesn't have 100000fart machine apps such a shame, but at least it can manage its resourses n runs smooth on a 200$ device....

If you read the android police comments on lollipop articles, every one is asking for a memory fix.

12. vincelongman (Posts: 4150; Member since: 10 Feb 2013)


Its basically fixed in 5.1
Most people on Android Police are complaining that 5.1 is being released too slowly (e.g. not released for the Nexus 4)\

posted on 28 Apr 2015, 04:23 2

14. rd_nest (Posts: 1591; Member since: 06 Jun 2010)


It's there for Nexus 4, i have it.
But it's worthless. If anyone is on KK, no need to install 5.1
Apart from few cosmetic changes, nothing in there in 5.1
Camera is still worthless, batterylife is useless. It sucks 7% while I sleep at night with 2G (not even 3G).

24. vincelongman (Posts: 4150; Member since: 10 Feb 2013)


Your camera and battery issues are hardware related

On my Nexus 5
Stock Lollipop battery life is the better than stock KitKat
Stock Lollipop battery life is about on par with rooted/modded KitKat
Stock Camera is the same since Google hasn't changed anything but aesthetics
But third parties camera apps are much better because of Lollipop's Camera2 API

I've heard most people with other phones, e.g. S5, M8, Nexus 6, have improved battery

I updated to 5.1.1 using a custom rom but the memory leak issue is still present.

36. vincelongman (Posts: 4150; Member since: 10 Feb 2013)


Wait for the official builds
Custom roms are always more buggy

Or maybe that's why Google hasn't fully released 5.1.1
Many they are still trying to fix it

Google definitely needs to improve their testing, and speed up their updates

Stock lollipop batterylife is not better, research more before posting personal opinion.

http://www.techspot.com/article/961-android-lollipop-performance-battery-life/page4.html

Apart from PCMark test, rest all tests like browsing, video playback, 4G the batterylife is same or less. So on what basis can you say L has better batterylife? Project Volta is useless.

Not Lollipop
Google/Samsung already patched the memory leaks in Lollipop, other Samsung lollipop phones don't have memory leaks

Its because Samsung introduced lots of tricks to save battery
That's the problem with them reducing the battery

It's not memory leak and neither the battery saver. How can battery be saved by system taking more RAM and having to relaunch apps.

It's the poor optimization or some bug.

>How can battery be saved by system taking more RAM and having to relaunch apps.
That's that I don't get, I agree relaunch apps uses save more battery

People are speculating it might be intentional since apparent some games are locked to 30 fps and games are the first to get killed off

But I agree its probably a bug

Its not lollipop its Samsung my friend. Note 4 used a lot of memory in kitkat too so you can't blame android more over why HTC phones are not affected, my experience with Note 4 running kitkat was same, uses a lot of memory, when my M8 uses 40MB it be using 110MB or more running same app.

If you see the phonebuff phone speed comparison, the S6 has to relaunch all the apps again instead of having proper multitasking. Update definitely needed.

Correct me if Im wrong, but its interesting to note that it is a "memory leak" caused by android 5.0 versions; however the One M9 in the test I am referring to is also running 5.0 without these issues?

5.1 from Google also fixed the 5.0 memory leaks as well

But Google introduced a new memory leak in 5.1
Some specific games cause system memory usage to increase by 100mb with each launch

No word on 5.1.1 yet

I do believe in real life performance over benchmarks too...I am a HTC fan yes, but I still stick to the fact that on-screen performance is the best measure of performance. If you have a SoC that can't run a high resolution as well as a 1080p, then isn't it falling behind? eg M9+ hahaha
