Hey everyone.
I just got my 4x HD and i was wondering why i always have around 70% ram used on idle.
I checked in task manager and there was for around 200mb of services and apps running max, can't find where the other 400mb went.
Anyone knows if this is normal? How much ram does your phone use on average?
I agree with 700mb ram already used. But doesnt lag the phone though.
AW: Ram usage
its better when more ram is used. all the apps u used are stored in ram for quicker app start when run the app again. in other words: phone is faster when more ram is used. only if u hit the 1gb limit the phone would lag

thats true, but i too have ram problem in my o4x,
it starts lagging and freezing after some time if memory is not cleared by any task manager. and at extreme it restarts the phone.
i haven't installed that much apps yet, i installed more apps in my HTC Explorer and that phone never did things like this but this phone has double ram and still doing strange things.
and i installed swapper to solve the problem but now i'm stuck on boot logo, any help appreciated.
and any help on my bricked phone is also appreciated at my post here, http://forum.xda-developers.com/showthread.php?t=2192894
still, my phone uses 800Megs of RAM and constant lag.
fyi every time someone complains that their Android phone is using a lot of RAM an angel loses its wings.

but.. but.. but how will the games work smooth if there's only 100megs ram free?
I understand that system/UI works faster when everything is loaded in ram... but i don't like apps in background sucking my battery. I've seen this clearly in Battery Monitor. When ram is clear it uses about 25mW (on idle), with stuff in background it's closer to 100mW or more... I don't like my phone eating battery 4 times faster on idle that it should.

Again, this isn't Windows, it's Android. Free RAM is wasted RAM. If it has only 100Mb free and you launch a heavy game, it'll promptly free the needed RAM by offloading the least used stuff it still has on RAM.
On the other hand, if you call that program you only use once a day, it's probably still in your RAM, and will open as if you've only just used it (well, almost).
The used RAM isn't necessarily active, so not all the apps stored there are sucking battery. Your test results are accurate, but your conclusions are fallacious: yes, there's less battery usage when the RAM is clearest, but, as they say, "you've thrown out the baby with the bathwater", i.e. when unloading ALL apps, you also unloaded the ones that were consuming battery. On the other hand, you've also thrown out stuff that were just kept in memory, but weren't active.
The other problem with your approach is that, after you unload ALL apps, the most troublesome ones will probably reload themselves back into RAM. So, even if right after freeing RAM you reduce your battery usage, a few minutes later it will be back to the same.
What you should do is get a program like BetterBateryStats and find out what's actually sucking your battery. When it does, you have a few alternatives:
- uninstall apps that are sucking your battery but you just don't need;
- greenify some of the apps that you do need, just not all the time;
- freeze some apps (with Titanium Backup) that you don't use but can't uninstall.
i tend to disagree with people saying free ram is wasted ram and preloading apps in ram is good and that for this simple reason.
everytime you start a app that is not preloaded (it can only preload so many apps) it has to use cpu time to unload it then load the next app resulting in extra cpu usage = less battery time.
many people complain about battery life except me.
and i really manage my phones resources all day long and have nsane results noone else seems to get.
i have over 5 hours 30 min screen on time (me browsing watching youtube using whatsapp and so on.) and have over 630 mb ram free.
my total stanby time on lght use is 5 days with 2 hours 30 min screen on time.
i would send screenshots as proof but for some reason the lg 4x hd bluetooth wont install on windows 7 x64.
but really since i starte to actively manage my phone the battery lasts longer and i never had a stutter or anything.
and as a sidenote my phone is stil unrooted and stock v10h so with root i could prevent even mre from starting up and have even more free ram and better results.
and yes the poster above me is right some apps will reload themselves so IF you use a task killed prevent it from killing tasks that start themselves up again.
like google partner setup , media and more google stuff.

I had that problem when I installed the first leaked V20A, now with the official V20A EUR_XXX bluetooth is working fine, faster tranfears than with ICS.
help
I have problems, too. My o4x is working about 2.5 years but im very angry because of the ram usage problem. The ram is always %70-80. And the phone is very very very... slow. If the cpu is works %80, what can i do ? The battery is finishing very early. I dont wanna new phone. Im not rich. I dont want to buy a new iPhone. Everyone say "The iPhone (ios) is the best. Android is the worst. Bla bla bla.. " And I believe this... PLEASE HELP ME (( :crying:
Ok my Samsung Note is 1 year old but it lags heavily. It is running Android 4.1.2. Almost all the applications lag heavily and I had a question about the RAM.
Out of total 1 GB RAM , my note shows the available RAM as 863 MB. But the problem is that RAM usage always shows between 700-750 out of 863 MB. I have checked and calculated the total RAM usage by all the applications (Including Cached Processes/Background process) and it is about 380 MB.
But still there is a difference 680 - 380 MB = 300 MB which no application is using........Who is using this 300 MB?.......Is there a memory leak.....Should I give my Mobile for repair for reflashing the firmware?.........Kindly reply.
Apart from changing the firmware then you can't do anything, this is normal with JB. If you want something lightweight then you could try OmniROM or CyanogenMod or any other AOSP ROMs.
I'm running official JB rom (rooted) and after a bit of tweeking it is running fine, with minimal lag. My memory usage is the same as yours, so I don't think that is your primary issue.
I suggest you do the following (as I did) :
. Backup all your apps and data using Titanium
. Factory reset
. Use the phone for a while without restoring to ensure there are no hardware problems. Performance should be good.
. Restore the essential apps you use. Again, use the phone for a while to ensure it runs without lagging.
. Restore the rest of the apps one by one.
In my experience the primary reason for the phone lagging is too many badly behaved apps that either use too much memory or hog processor time via wakelocks, etc.
Badly behaved apps unfortunately include some bloat that Samsung put on your phone by default. I had to disable (freeze via titanium) some samsung apps, such as Vlingo before my JB worked well. Use wakelock detector and cpu stats to determine which apps are misbehaving. If you just leave your phone alone most of the day you should be seeing around 70% deep sleep.
Good luck. Hope you get it sorted. I was about to trade up my note for a note 3 but after the optimisation I don't think I'll bother for a while because now my phone runs very well and make no mistakes, I am a heavy user.
Rich.
Try another Rom. IMO Omnirom is currently one of the best. http://forum.xda-developers.com/showthread.php?t=2516933

this must be some kind of joke

I'm not an expert, but I'm under the impression that "unused RAM is wasted RAM" and therefore high RAM usage does not imply that there is a problem (in fact it implies there isn't)

You are correct but the ram management is atrocious on the s6. Can't even go back and forth and between apps right away. Frustrating as bell with lots of apps I use. Wish I returned my s6 and stuck with note4 awhile longer.

While in theory this seems right... but RAM should not be used, especially at such a high amount with nothing running; for battery and smoothness sake. RAM of this caliber should be idle and quickly used when things are launched. Furthermore apps in RAM shouldnt have to be relaunched and slowed down by RAM, the whole RAM situation is ****ed.

This totally makes sense.. my point wasn't that RAM management isn't poor but rather that RAM used/available isn't the right metric to be looking at.

Really? No seriously REALLY? Would you rather that crap gets cached on the storage? Ram should not be used is probably my all time favorite quote now. Ram management is poor yes but it using around 85% ram is a good thing, any modern day operating system should do this, especially android for reasons that should be pretty clear.

Makes sense... Let me open AutoCAD on my computer which chews 16GB of RAM, close it out, and then have 99% RAM usage because of caching; on my modern day operating system. /s
While I understand RAM Management as a big issue, Im saying RAM should not be at 85% with NOTHING, ABSOLUTELY NOTHING, running. Android shouldn't be any different, not EVERYTHING gets kept in volatile space until you reboot or just so happen to go back to that one thing that could sit there cached for days.

If you are using a app that uses 16gb of ram chances are you have 32GB of ram, so windows would use what 10% of the ram with nothing running? Get where I'm going with this? When I say 85% is good I mean if you have 3 or 4gb of ram. Ram management is the only culprit here. My g3 used the same amount of ram and worked just fine. I should have been clearer sorry.
It using most of the RAM isn't a bad thing. It just has to manage what is being used, better. After running 5.1.1. In my use I have noticed that it's more agressive. Apps are constantly reloading when sometimes I switch to one app and then go back to the one I was previously using. On top of that when I go back to my home screen the icons and weather clock widget have to reload as well. I've got hope that this issue is resolved either officially via Samsung or the great people on this forum.

I think the thing most people miss is that there is NEVER nothing open. I can reboot my phone right now, and within 10 seconds of booting there is over 30 apps in memory, usually 40 or more. Touchwiz is awful, there is so much crap that runs and since something depends on it you cant disable or remove it. And, lets face it. There is something wrong with the S6 in particular. Im not saying its hardware, but something isn't right. Maybe it's because its arm64, maybe it's the new octo processor. Only Samsung really knows.

Youre right, the way Android handles memory is a bit different than a PC. 85% being used is typical across most devices with 3gb of ram. The problem is that even with 2-300mb free (literally free, not counting cached) the S6 takes a huge hit in performance. Which is why Samsung set memory management so aggressive. I think it can be fixed, but I don't expect Samsung to do it.

Don't get me started on 5.1.1. Wait til other variants start getting it and more people see how much more aggressive Samsung set memory management. It's a nightmare. I've spent 3 days, probably 20+ hours trying different dha settings and nothing works except very very aggressive values. It's ****.
Unused ram is bad when I use apps they get the ram they need. I have apps OPEN, plenty are open right now and I have half used by the system the other 1.5 gigs half is used by my current apps the other half of that is empty. Nothing is wrong a bunch of you need to understand that unused resources is bad, the system lets go of cached processes when an active processes needs ram again nothing is wrong. This is the same line of thinking people use with task killers just to see a higher amount of empty ram and slowing down their system thinking its faster because they see a higher % of free ram.
This is the best phone I have ever had and I always own the next big flagship every 3-6 months everyone is saying there is a performance issues. Where? Please show me because I dont see it dual screen multitasking is smooth as butter I never close a single app. Right now I have netflix, need for speed, unblock me, google maps, email, camera, web browser, my-tmobile, a live wallpaper, s health, youtube in my active app list and my hotspot is currently on. What are you all going on about??? I came from an iphone 6 with one gig of ram and I saw ram issues daily I had to be conscious of leaving apps running,not with this phone.

I only noticed one that really does that the play store, I really have not lost my place in many apps. I think its up to app programers to fix that though because only certain apps have that issue. My games stay where they were the internet app just refreshes my last page, youtube is still on the video I have not finished since this morning, netflix is still where I left it.

Unfortunately oom adj values are assigned to apps by services.jar. doesn't matter what app developers do, Samsung places priority on their own stuff. If you haven't tweaked any memory stuff and you're honestly able to switch between all that stuff you have a special device. We haven't all been freaking out about the crappy memory management for nothing, I assure you.

I hear you, I wish I had time to make a video to show you guys. I just have a lot of the stock apps disabled on the latest OTA update. Maybe it is happening frequntly with apps I dont use. 5.1.1 fixed all my problems with this phone which was mostly battery related the idle battery life is actually normal now. I think I can legit get two days out of one charge now with light use, I am at 74% since this morning I am going to sleep and leaving it off the charger tonight so I will see soon. I just know that plague inc and the play store is the only ones that loses its place for me.
I did flash 5.1.1 over a rom and it kept the hotspot hack from that rom so maybe it kept the roms memory tweaks as well. If thats the case I am not touching this phone anymore and keeping it as is.

There's no way anything from the ROM is left. Especially if you updated via Odin. If the hot spot hack is still working it could be because you didn't wipe data, only possible explanation. As far as batter life goes, I've always consistently lost less than .25% an hour, pre and post update. I sleep 8ish hours a night and never lose more than 2%. Which is astonishing considering the size of the battery in this phone, and the CPU.

My phone left alone burn up battery before the last update. I used odin and yes it left my apps and settings, ringtones, themes ect and i dont know why and the hotspot hack is very much working at 23 gigs last check. I restored 5.0.1 on odin said it failed but booted and root was missing then updated anyways. I wished my battery was that good before the update now I got 2 days 7 hours off charger with 3 hours 40 minutes screen on with 13% left on my last charge.
I've only been really using my S6A for a few months, and in that time it has been getting exponentially slower, now to the point that it lags several seconds before showing the home screen. Upon checking the stats, I noticed that the RAM was almost topped out, and even a ram cleaner couldn't keep more that 200Mb free. I've heard this may be a problem with touchwiz, but I'm curious, is it really a common problem, and is there a fix? P.S. I only have two user apps running in the background, and they usually take up 50Mb of RAM between them, so it's not that.
My old Samsung galaxy express had an issue like this to the extent where I got annoyed and switched to the moto g3. If you use any app such as clean master, you may think it works, but it actually doesn't help, it makes performance worse.my suggestion is to uninstall any cleaner apps if you have any and restart your device.
Hi so I keep noticing my RAM begins to run low after a couple days. I sit around 2 or below free with no apps open.
Is this how the phone operates normally? I have nearly every app put to sleep when not using under the batter settings.
What's your available RAM after a few days?
Thanks
Completly normal situation. That how Ram memory works. You will not fell better perfomence seeing more free ram, but you feel boost when ram is used. (to start app quicker)

If you want to free ram just reboot phone
I usually see between 3 and 4.1 ram available, I have setup auto reboot in the device care, my ram used to be consistently about 4 available until the last update.

How often do you reboot?
Set it up for once a week as you can only have once but you can also setup auto optimisation and have this every other day
