At startup and in general, how much program memory should be in use?

I know there's probably no right answer for this, but i feel like my program memory is always very high and am wondering if that could be what contributes to my poor battery life.
I just started my phone and it says using 28.8MB out of 48.8 (which is lower than sometimes). One of the things that bothers me is when i run a few programs but then close them i don't always see the memory usage drop back down to below that 30MB mark. Sometimes it'll stay up at 35 even with all programs not running. I'm wondering what levels other people are seeing and if mine is high, why?
BTW, I am running K's WM6.0 on an 8525 of Radio 1.47.30.10

Im running MRH 4.5.1 which uses CRCs R9.1 and with my phone on for the last 24-36 hours I just closed all the running apps and checked my memory and Im at 27.35 MB in use and 21.33 MB free.
So compared to mine, yes yours does seem a little bit high, especially since I can launch stuff and fill up the memory but as soon as I close it all down Im right back to around 28 MB in use.

Depends on programs you've got installed and whether or not they are set to startup automatically.
After a reboot I am using 23.35 MB of ram.
Search in the /Windows/Startup folder and delete what you don't want to startup automatically.

Also keep in mind that every folder, start menu, settings, you open will use up some memory. For example if you go to Start/Settings and wait for it to load. Then click on the System Tab, you will notice it takes 1 second or so to open. If go back to the Personal Tab, and then click on the System Tab a 2nd time,,, you will notice it loads immediately. This is because all the "icons" are loaded into your memory. Same thing when you click on your Start Menu the 1st time, there is a slight delay. Then when you reopen it, it opens immediately.
This is common knowledge but closing an App with the X doesn't always actually close it. I recommend downloading a good task manager that allows you to view memory usage and processes. I'm using Task Manager 3.0 by Fdcsoft.
Then lastly, their is an app by Oxios called CloseApps 1.40,,, this will free up some memory even after you have ever application closed. I just used it to get the version number and I didn't have any app running. It just now freed up 3300kb of memory for me.

[Q] Process lifetime

I was wondering if there's any way to prevent android from killing programs immediately after i press the home button or switch to other programs.
For example, I'm browsing the Web when an sms comes in. Using home button (long pressing) I switch the task to answer and when I come back, the browser is gone and i have to load the page again (although it reloads in the same state).
It's really annoying. Reloading a webpage is not a problem but what about playing games?
I'm running InsertCoin 1.5, have about 80- 90MB RAM unused. And I doubt that I had RAM shortage
Thanks for reply

Your brought up that old horse (debate) on why the android OS does or does not need task managers. Yes, the wonderful engineers at android, developed a platform unlike windows, manages processes (by some opinions) way better than Windows. When you switch screens, it freezes the process, and holds it until you come back. When the phone starts to run out of allocated memory, it starts to kill the (less used) processes.
Now, I've heard of allocation of process levels to cause some apps to continuous run, which would be an interesting development for some dev to take on. You can select what apps you'll like to constantly run even if you switch screens. This would help those who would want to quickly drain their battery for OS calibration purposes.
If I find such a solution, ill report back.

Android should never kill the 2nd process in line (aka the Browser when switching to SMS), unless you're extremely short on RAM. In low RAM conditions, it will kill the farthest from recently used app in order to free up RAM.
How often do you notice this? is it always killing the app you switch from? Because this isn't correct (unless you're literally out of RAM as I said).

Like i said. I had plenty of free RAM. So it's unlikely that I have RAM shortage.
I spent the morning examined things. Just figured I it out:
Flash this over and I have 3 apps in line.
Combine with Perfect task switcher, I got what i wanted.
Also, I noticed that switching by long pressing HOME button and choosing apps cause the app to restart while using BACK button won't
I don't know if this is Android behavior or my device's issue
But anyway, I got it sorted out
Thanks you u guys

I'm running CM7. Long pressing home and switching between numerous apps I've never had an app close on me. Must be a ROM/device combination situation for you...

UK G3 memory

Well I've got my g3 and after 2 days use I've noticed that with its 2gb memory it constantly uses 80% of it even on standby with no apps open. I did a factory reset and didn't install anything and it was still using 72% of the memory. Anyone else noticed this or is my phone faulty.......?

I think this is how Android works, it fills the memory then kills things it doesn't need. There's also ZRAM active in the kernel which uses roughly 25% of the memory as swap space.Heres a snippet from an article on Android RAM....
The problem is that Android uses RAM differently than, say, Windows. On Android, having your RAM nearly full is a*good*thing. It means that when you relaunch an app you've previously opened, the app launches quickly and returns to its previous state. So while Android actually uses RAM efficiently, most users see that their RAM is full and assume that's what's slowing down their phone. In reality, your CPU—which is only used by apps that are actually active—is almost always the bottleneck.

Its not so much Android as how Linux manages memory. The memory usage indicated includes memory used for cached apps and information, or swap etc. In saying that LG's version of android does use more memory than stock AOSP android on say a nexus 5 (1.2gb~ on G3 compared to around 700mb on N5)
But the rule still stands true, used ram is better than unused ram.

free ram is wasted ram.

So? What's the problem? Using RAM is good, it's what it's here for. Android will try to keep in memory as many apps as possible, and when it's full, it'll start killing old apps to free ram for new ones. Don't worry about that, it's how it's supposed to work, and Android is very good at that. You should never have to worry about killing apps yourself, and you won't see any bad performance impact because of high RAM utilization. These "task killer" apps out there (including the default one on your phone) have only one valid use case: killing an app that's not responsive, in a connection loop, or that you wish to manually reset for any other reason.

Well thanks guys for your replies. Had no idea that's how android worked. Just goes to show you learn something new everyday.

[Q] RAM Usage

I've been noticing some slight lag in unlocking, the screen coming on, etc on my new Note 4 from time to time. I've found that going in the app switcher thing and clearing all remedies the issue for a bit.
I was curious recently and looked at the RAM usage in that screen and was surprised to see that ~2.1GB of RAM was being used, even after clearing all recent apps.
Is it normal for the thing to be using over 2GB of RAM at all times? This seems very strange to me.
Thoughts?

I'm pretty sure its normal because mine is also using 2GB after clearing all. After a reboot, it dropped to 1.6GB before manually launching any application. I'm pretty sure Android is designed this way.

The way android is made and runs, it uses almost all RAM at all times... Basically "unused RAM is wasted RAM." All of our phones have run this way since the time of I'm.
Now, with respect to lag, that's all the bloatware forcing itself to be the main process or close to it. Only way is to fully delete (not only disable) all of them and their underlying processes.

Thanks for the replies, guys. Just waiting on root, then bloatware will be gone.

Well said..

Only time I have lag on the lockscreen is with a sub par sd card. Once I got rid of that junker the lag went away. Try removing your SD card and see if that fixes the lag.

Phone freezing twice or thrice a day ! Tried all reset options !

Hi All,
Anybody here with the same issue ?
Looks like a software issue/touch unresponsive issue because usually I find it coming back to normal once I press power button and unlock it again.
Sounds like RAM allocation issue, isn't ?
Thinking to sell it. Please suggest if you guys know a better way to deal with it !
Even if I go to SC, I cannot reproduce the issue at that particular time. They will just reset it and give me back, and that where I don't want to waste my time.
Does this looks fruitful to flash stock firmware again by the unbrick way ? I feel like that will be me last try.

You seem new here, so welcome on xda
One thing you should keep in mind is to be as precise as possible when presenting an issue, your description right now is not very clear, by the title it sounded like your phone actually froze, which could have been a ram or even a power management issue, but after reading your post it seems more likely that your display was wet, or that you were charging your phone, capacitive touchscreens are sensible to that.
Usually a frozen phone does not respond to the power button like yours did, and a ram issue seems very unlikely tbh

My style of using I believe is the same and I had no such issues in my Cool 1 ever in an year. Was a lot better in every way. Picked it up because I loved the looks, but have lost my trust on Huawei. They really need a lot of improvement.

i am having the same issues as the OP (Although i don't know what he means by "going to the SC")
the phone just goes through moments of extreme lag for about 10-30 seconds, sometimes longer, and it makes the phone COMPLETELY unusable during those times. it happens at least once every other day or so, sometimes several times a day, and sometimes it only lasts about 10 seconds, although on a few occasions, it has lasted several minutes, the phone will "attempt" to respond to inputs, but it gets nowhere quick, opening apps i did not click on, closing apps that weren't open, black-screening, half-screening (app on half the screen), etc.. sometimes i have to just power cycle..
i have the exact same feeling as the OP in that i want to sell the phone. (although i type much better, i'll assume english is a second language for him/her)
i like EMUI a lot.. although i think i want a galaxy s8/s9 now.

Since yours is the us variant, I'm assuming you've got 3 gb of ram instead of 4 gb, in which case a ram issue seems much more likely.
Not much of an issue actually, just that you probably had lots of apps open at the same time, leading to almost full ram (so the system starts closing background and even foreground apps if needed, leading to the strange behaviour you noticed).
Just remember to close apps you don't use and you'll be fine

It's 2018 and I think the OP and I know how smartphones work. I am coming from a phone with 2GB RAM and it has no such issues, no matter how many apps and/or games are open. Google explicitly states that closing background apps is unnecessary, and I should think EMUI offers an improvement over stock Android, not a detrimental experience. However, if you are correct and it is the RAM, it is not acceptable and needs to be fixed or I'm buying a new phone from a different company. In today's world, phones will open links to Chrome and from Chrome open reddit, xda app, pinterest, link to Facebook, share to Twitter, etc etc.. every time I click on a button I should not be having to back track to make sure I only have a certain amount of apps open. Nougat limits max open apps to 20 BTW, marshmallow it was 30.. But RAM management CPU management should be better. If it's of any interest, my reported "free" ram always stays at or above 1-1.5GB so I don't think its ram.. CPU or software problem, possibly.. But my Temps are good as well. Yes it's the 3GB version

Just a quick thought of something you could check (I also have the US 3GB version and was experiencing the same issue). Open up Settings > Battery, and other the "Other" section click "Consumption". See if there's any apps there that are keeping the phone awake and preventing it from sleeping. I would get constant lag after only a few hours of use, and it was intermittent just like you're experiencing. I was about to send the phone back, but checked this setting first. Turns out, the CNN app was running the CPU at nearly 100% for hours on end and preventing the phone from deep sleeping. Once I uninstalled that app, I haven't had issues since then. Could be something similar, just a thought. YMMV.
And by the way, it's NOT the ram. 3GB is plenty. You can see how much is being used on the app select screen, and I've never used more than 1.5 with a ton of apps in the background.

Let me help you there guys....i got the US variant too and has these freezing and lags all over the place, what i discover and did was:
1- Not all the apps works well with the phone hardware(they told me that somewhere) so try to test the apps you put on the phone.
2-Delete all the unnecessary apps from emui, that will give you less lag.
3-Check the battery consuming apps like the guy said and if you want turn on the close apps on screen lock.
Now after all of these my phone have been moving better but the problem isnt the ram, is the software so wait a little more so they can fix this cause is really a good value phone

It has to be the RAM management. Huawei must have optimized the software for 4GB, and then released a US 3GB version without changing anything, so it's screwed up even though phone is showing lots of free RAM.

Wao man thats the best explanation for this problem thanks man

It isn't and never was a RAM thing. Android's memory management essentially force closes apps (but shows them in recents) if it needs more memory. Note there is no work involved in that and you'd never know it until you switch apps and it has to reload, shows logo, etc. Amazing how non-solutions we're brought up multiple times and even thanked. Insert that's-not-how-any-of-this-works meme.

Well, yeah, ram issues nowadays should not be present, but I do speak on a basis, I have experienced bad performance and foreground apps getting killed on a nexus 5, which has 2 gb of ram and stock android. I have no idea what's emui's ram management policy, but on a scale, this would be the least likely cause for sure
