[Q] 4.0.2.A.0.42 - Memory Hog?

Hey Guys,
I have been running this firmware for around 3 days now, I noticed it uses around 50mb more memory than the 4.0.A.2.368.
I have removed exactly the same bloatware, and have the exact same applications, usage etc
Any ideas on how to improve the available memory?
Obviously the more being used i= more battery use and that is also noticably shorter than the previous firmware I had.

Nobody have any ideas?

Seems there are more open processes in the background that's taking that memory up.

You gotta remove background services that you don't use (and that aren't vital to the phone's stability of course) if you want more free working ram and less battery drain. Static cached apps use pretty much no battery, but services do. I hacked and slashed away at my system apps until I now have no apps left that aren't vital to the phone or to me. After applying the Dalvik2cache mod and moving many user apps to SD, I have about 320MB free ram and about 185MB free system space. Seems like plenty to me, and the battery drain isn't that bad for me either now that I have barely any services running

it's called Android memory pooling, linux stuff.. the more memory used, the better your phone performs..

[Q] [Q} Acro S low RAM problem

Hi there,
I have a question to Xperia Acro S users: How much total RAM can you see and how much free RAM on your phones?
I have my acro s since few days and I'm a little bit disappointed. In normal use I find it a bit laggy and slow. I tried it on 6.1.A.2.45, 6.1.A.2.55 and XTXperience_9. All the roms the same problem. I installed "Android System Info" and it showed total RAM 634Mb and free RAM 196Mb.
Both my previous xperia p and my tablet ainol novo 7 flame are showing total RAM 809 Mb and more free RAM. Each of devices has 1GB RAM according to official specs.
Why there is such a difference? Anybody knows? Is there any solution?
I installed additionally "Quick system info PRO" but the same results.

From the Total 1GB RAM, around 200 MB is being used the by Adreno GPU. Some are kept reserved for the OS and rest amount of RAM we get for the apps and general use.
I am using Firmware 0.50 and honestly i don't feel that much of lag actually. If you are on Stock ROM then try this two apps from Google Play.
RAM Manager Pro and Pimp My ROM. These are really great tweaking software.
And it's not about how much free RAM you have, it's about whether the RAM optimization in your device is good or not.I have only 130 MB free RAM but my device runs quite good.

People are far too ram obsessed. U could have 80mb free and you'd never notice unless you looked. My advice. Just stop looking and use your phone

Thank you for your reply, specially because you've written about it before. I've searched xda for this topic, but didn't find answer.
I know some of RAM is used by GPU, and some reserved for system, but I wrote the question because my xperia P and ainol (both 1GB RAM) are showing 809 total and over 400 free RAM. I wouldn't care about it, I wouldn't even have checked it if I wouldn't feel my acro s very laggy comparing to my mentioned devices. Both are worse in specs than acro s.
I'm running 0.55 stock ROM right now, I'll try the apps you suggested. I bought my phone a week ago, and hoped to be more satisfied than with xperia p (no micro sd, no watherproof, smaller screen, and so on). Now I think xperia p works better for a daily use ;/

Thanks for the list. It's a good idea to disable some of not used apps.
I still can send back my phone to shop (according to polish law when I buy via internet I can return it within 10 days), but I want to convince myself, I don't have to

No problem. Sometimes some apps like Facebook or Google play consume high amount of memory like 80-90 MB while opened for long time. So try force close these once u have done using those apps. If the RAM properly distributed then even if you have 70-80 MB free memory in total it shouldn't be lag at all.

[Q] Out of RAM

Hi,
working daily with linux-OS and beeing actively using custom roms since Android 2.1 I have a bit of knowledge on RAM usage on Linux and Android. As many know and like to post "free RAM is wasted RAM" - we all know that. But why? Because all not actively used RAM (lets call it "free") can be used as a cache for applications you likely will need in future. But what if your GNEX runs out of free RAM an is not able to cache any more? What if you start a new huge application like your browser and free RAM has to be obtained to give it to your starting application? Yes - bad things can happen!
But lets start from the beginning:
1. If you go to Settings->Applications->Running you get the RAM-bar at the bottom of the screen. This is splitted in two parts: used and free (like defined above). Used RAM seems to be actively allocated RAM which cannot be used for other things like starting applications and free is the RAM which can be obtained because it only containes caches apps which are not running.
2. Directly above that bar you se a kind of brace which seems not to be just eye-candy but has some meaning: The lower and thiner part of that brace seems to show the part of that RAM (used or free) that is used by the applications/service in the list above. Example: if you switch to cached applications the brace will jump to that part of the bar and by killing some of the cached apps you will change the width of the brace.
Lets put things together:
viewing the used RAM you will notice that the brace does not cover the whole used-ram-bar but, in my case, about the half. I also noticed that the width of the brace does not change greatly with uptime of the device as all listed services will stay at their size more or less so their sum is not going to change greatly. In my case all services sum up to about 250MB meaning the braces width is about 1/3 of the screen assuming that GNEX has 700MB total RAM (the rest of 1GB total physical RAM is allocated to other parts of the SOC-chip like Baseband and GPU and not available to linux-kernel or android).
But one thing does change greatly!!! The part of the used-ram-bar which is not covered by the brace will be very small after rebooting and will grow with uptime. As the part covered by the brace is a fixed factor this means that the free ram is the trade-off for the growing uncovered part of the used-ram. In my case I get after rebooting the device: 250MB free, 450MB used of which 250 are covered by the brace, leaving 200MB used RAM for whatever (kernel, non-android stuff like filesystem caches, ideas?) After some days of usage this changes to 50MB free, 650MB used of which still about 250MB are covered by the brace, leaving 400MB used for other things (NOT app-cache).
Consequences:
From the assumptions above this means that android is not able to cache apps anymore (because they live in the free RAM) and my device beginns to lag while opening new apps. To obtain enough RAM for starting apps like browers (stock or firefox tested) it will even need to kill services!!! And in extreme low-memory situations it even kills the foreground app you are using (to me it happened while I used firefox). Also when you go to settings->applications->running again you will notice that android will be restarting your services over and over again to obtain more RAM without much success. In the situations my actively used firefox got killed something different happened: the launcher also had been killed because it was starting over but more importently settings->applications->running showed that much of the used RAM not covered by the brace was gone! Free RAM jumped from 50MB to about 200MB which is nearly what I get after a fresh reboot. I assume that in this extreme low memory situation also the kernel did clean up things.
From my observations you will get the following if your free RAM accoring to settings->applications->running is very low:
1. no cached apps if you swich to settings->applications->running->cached
2. laggy phone
3. your launcher gets killed more oftern when returning from e.g. browser
4. more apps get killed when returning to launcher meaning that they will get restarted if you return to that app
5. in low memory situations (app does not fit into free-RAM-part) services will get restarted frequently
6. in extreme low-memory situations kernel cleans up everything (i guess)
The question now is: what is using so much RAM and growing over uptime until our GNEX has no more free RAM? I alread checked different ROMs including stock 4.1.2, stock 4.2.2 slimbean 4.2.2 cm10-stable cm10.1-nightly and all of them show this behavior. The only thing I noticed: all 4.1 ROMS perform better in this area: their RAM does not fill up that quickly but it does. On 4.2 ROMs it takes just few days to run out of free RAM for me. I already wiped my device and installed only realy needed apps (20 out of 140!!!) but it still happens.

I think this happen in any OS
A daily reboot is always a must in my opinion, to free ram, to stop some services, to stop wake locks, to stop battery drain without sense..

That's what always makes me ask : Is Gnex really have 1gb of memory?
Other phones with same spec. uses same OS have more than 693mb that in gnex , why the hell our phone has the lowest read ram in 1GB category phones
I'm sure this is the only weak-point in gnex

300MB is GPU reserved for camera.

I didn't engineer the device. But I presume it's a requirement by the GPU PowerVR chip, since it uses alot of RAM on the Nexus S, which had the same chip only downclocked. It was 330MB usable out of 512MB advertised there. The amount reserved is bigger on GN obviously because of HD video capture option.

I agree GPU shared system RAM, but 300MB is wayy too much bro. I checked my N4 it has 1.82GB of 2GB total considering N4 Adreno and camera chip is more powerful than i9250

It's (again probably) not because of the speed/power etc. but that it's like that by design. Adreno ain't the same as the one used on GN, so there's no comparison.
I'm sure Google didn't allocate that much memory just to screw us up, but instead there's a legit need for it. For instance, the amount of RAM available on a Galaxy S2 is much bigger, around 830-850MB out of 1 GB and it has a completely different camera/GPU combo, spite full HD video and 8 mpix instead of GNs 5. That's why I presume it's just PowerVRs "fault".

Perhaps, i just checked galaxy tab 2 ics available ram, it less than 700, but after flashed stock JB, it shows more RAM, about 770MB. Tab 2 uses OMAP and PowerVR right? Imho. i just curious why it reserves so much ram. Searched google and can't found the reason :S

*Update*
An galaxy S2 with all stock (Android 4.1.2) shows the same amount of used RAM after 10 days of uptime (380MB free and 380MB used - a nearly perfect 50/50 ratio). No sign of degradation so far. Honestly this phone is not used much but still it feels very different from what I see on my Gnex.
Has someone shorlty fully wiped and reflashed his phone to stock 4.2.2 (JDQ39). How does the RAM usage look like after fresh reboot?

RAM problem
This is what i get today. Using liquidsmooth 2.4 fraco kernel. But i know its not abut apps i use. I dont know where are all that RAM. After reboot with same apps runing in background i have 230-260MB free RAM. But if i using phone day or so it look like this.
Phone get laggy, slow with high latency. Im not sure if its 4.2.2 bug for Gnex or just some mess with ROM but its same on any custom ROM. ill try flash stock and see what i get.

Hi, this is exaclty what i was talking about... very frequent service restarts and laggy phone and even basic things like keyboard and music-playback can quit while in use. While I tried to compose an email to send a screenshot to my desktop to post it here my stock-mail-app died and the phone rebooted. At least I have now both an after reboot and an after two days of using PARANOID ROM screenshot
I recently switches to PARANOID 3.55 and now have even more issues as the phone boots with just 200MB free RAM. This ROM seems to demand very much RAM.
BTW. I installed Stock for more than a week before switching to PARANOID and had around 260MB free after booting and around 150MB free after some days of usage. Increase was ways lower than on any custom rom. Can anyone comment on this? Same or contrary stock-experience?

Stock JDQ39 rooted. (running one week)
kernel stock or lean both are perfect and have no affect RAM or smoothness. Screenshot is after some days of full usage. Battery life i getting is about 1day with 2h screen on.
now someone tell me that its not custom ROM problem. 4.2.2 stock is just awesome. Im sad that custom ROMs not..

Next step would be to deodex this ROM and to try again because Stock is odexed in contrast to any custom rom. I realy would like to figure out the reason for this bad RAM usage on custom roms.

yes im on odexed rom. and im curious if deodexing some custom ROM will help with this. I think about slighty modified vanilla rascarlo ROM with kernel that work perfect lean 6.4 is smooth like stock and dont broke anything. Its deodexed rom so i can propably try THIS to odex it.

I thing you ment odexing some custom ROM, right? I'm thinking about to try the odex-me apk you can find on XDA which will odex all apks from /system/app but leave the framework.jar stuff untouched. But its far more easy to deodex the stock ROM and to try again

[Q] Rooting Sony Xperia ZL C6502 - Build .244 (India)

Hi All,
Using my New ZL from a month now. My first android phone. So i have very little info on apps and other things in android.
I am very happy with this super fast phone and with lot of features.
Two things are bugging me.
1. Heat
2. Battery
After playing for 15 mins phone gets really HOT, after searching in the internet found that all games & apps are clocked at 1.5 GHZ continuously and that's the reason. So i want to root the phone so that i can control the CPU usage.
Battery drains quickly because apps constantly run in the back ground, even when not used and I want remove lot of unwanted apps which i never use.
Here are my questions :
1. Will rooting the phone erases all the data (game saved files, contacts, songs, call logs, messages, applications etc..) ?
2. Which application to use to control the CPU ?
3. Which application to use to extend battery life ?
4. Which application to use to stop applications running in back ground ?
For Rooting purpose i want use this method - http://forum.xda-developers.com/showthread.php?t=2327473
Can i use the above method to Root my Phone - Sony Xperia ZL C6502 - Build .244 (India) ?

[Q] Memory Management Question

I'm running a stock Sense 5.0.1 ROM with the ElementalX kernel. For ages I've been annoyed at how apps (the 5th last used and above) require reloading when going back to it. I thought 2GB of RAM would be enough for multitasking of around 9 apps or more. I recently noticed in the running apps screen, in the cached apps menu that it shows ~450mb free and it will always hover around that value no matter which apps have been running or how many.
I was wondering whether this is due to the memory issues I've heard from 5.0 builds of Lollipop, poor memory management of Lollipop or HTC's LMK settings. Is there any way of decreasing the amount of free memory available?
