I've just posted a new Beta of my MoDaCo Custom ROM here with 128MB Compcache by default.
I'm interested to hear thoughts on whether it's going to be worthwhile!
The RAM use on my N1 is always near 100%, and with the CC enabled, I see it being used...
I'm no Compcache expert, so i'm interested to hear what others think...?

The best thing about the Nexus One is how fast it goes, and the RAM that allows to have lots of programs at the same time. For example, my browser almost never need to rechargue the page after using gmail or some other app and then returning to the browser, while my G1 does it almost always.
Sometimes I use advanced task manager to kill all apps and it does kill 15-19 apps! On the G1 it never killed more than 4-8.
So, I don't think this is really needed on the Nexus, if it improves things even more, cool, but I would dedicate your developer efforts to other things.
Sorry for my non-native english.
Off topic, but your "non-native english" is a lot better that that of many native speakers!
Back on topic, I' sure it would get used, since Android will keep filling RAM until it needs to clear some down (correct me if I'm wrong here), but as for whether it's needed? I'm not so sure. The Nexus seems to cope with keeping pretty much all the apps / data I am generally using in memory no problem (as juan says above 15+ apps no problem).
I dont think any form of A2SD, CC, or Swap is needed on the N1. It has more than enough RAM, and keep in mind that not all of it is unlocked yet! 100-200MB more RAM will be unlocked when Google fixes the kernel and sends out an update (or maybe cyanogen will implement it into his ROM?)
Compcache will probably help a little. The configuration is going to be key. DO NOT USE backing swap with it. If I wasn't getting my N1 replaced, for the second time, for dust under the screen I would do some benchmarking for you and give you actual numbers. Maybe when I get my new one and unlock it I will spend some time on it.
with the 1G CPU CompCache should not slow down the UI. For heavy use it should help...
I think that Linux Swap would be nice too since it could unload some of the memory that is not used on to it. If we set swappiness at 0-30 it would hardy use it but instead of dumping the processed data it would just cache it on the swap partition.
I guess the only way to say what works would be to do some testing and see.
i DEF need A2SD i dont like that everyone is saying its not needed...i am at the end of my app storage space and get a notice im running low on space, and when it gets to that point i cant recieve any more text messages

hey man ... I've already experimented a little myself with cc.
In my experience for the "android experience" on nexus1 (and considering how android will always try to grab what you throw at it) ... there could be some minimal improvements when utilizing it.
What I've seen thus far ...
In order to leverage cc without a significant performance impact ... changing the way the CPU performs CPU frequency samping/scaling is something that should be addressed in concert. Unfortunately we then begin to encroach on the battery draining issues.
With some minimal tweaking, cc can add a *huge* amount of available RAM.
But in the end .. I think for the typical user the benefit will be minimal.
However, for me personally ... (just for fun) ... I ran a test debian linux distro loaded up with Xorg+WindowMaker (my lightweight favorite combo) ... and the increased RAM made a significant difference. I *almost* had a fullly functional linux desktop in my hand!! Was quite neat compared to the old days of trying the same on g1.
Anyhow, just my 2 cents for now on the matter ... I'm still toying with these implementations myself. If I have anything more to add later that has significance I will.
~enom~
Please enomther, can u share with us your debian distro ready to run under the N1?
because i want to try port Archlinux like debian under the n1.
Im using it on my desktop, and is realy more light and faster than debain

It's a chroot'd environment/setup ... running of ext3 on the sdcard ... (still too big for the NAND) ...
Then I run Xorg through a localvnc script setup ... I then use a android VNC app from the Market to vnc into it and control it.
Still interested?

Yes of course, i have a thread ready on arch forums but i want to try first debian and see how much stable and functional can be on the n1.
If u can use it like a desktop really, then arch, must be almost 3 times faster deleting packages, daemons, etc...
Im a newbe on linux of course, but i can try it with help
Here is the project: http://www.archmobile.org/trac/wiki/AM/Installation/Guide
Im using arch for 1 year and im really happy with it, beats ubuntu hard! hehe

Disclaimer: It's *almost* as functional as a desktop
Limited by the android vnc client of course. When running with Xorg the resources are juiced (thus the need for compcahe, and why I posted it ... slight relevance) ... but sure ... I need to set one up from scratch for arm (as mine are riddled with custom data/packages) ... and I put something up for you. I'll PM you about it ... give me a couple/few days (got a big weekend comin up).
Neat project btw .. I'm definitely going to pull it down, check it out and play!
@modaco ... sry for the 4-post thread hijack

Of course dude, when u want and when u can
By now, i just have a 500mb ext3 partition on my sdcard, with the base system of archmobile ready
As i said, im newbe, and now i need to know how can i boot it hehe
never tried it on android, but the usual way is to mount-bind /proc, /sys, /dev from the running android into the new root and then just chroot into the new system.
like
mount -o bind /dev /sdcard/arch/dev
... /proc
... /dev
chroot /sdcard/arch
then you can start services like vnc.
i doubt that arch will be so much faster though.
don't get this wrong, i used arch for over a year and really like its concept. but in the end when you compare fully customized installations of arch and for example ubuntu, the speed difference is rather minimal.
(with focus on customized, meaning on arch you install what you want and on ubuntu you remove what you do not want )
Thansk xkonnim i'll try to give it a shot
enomther, how you boot the debian?
I men if you are using it natively trought fastboot or a img from the sdcard partition ?

Hi dude again
Finally i got chroot on my arch partition
I have it under /system/sd
and i have the minimal bash working
Now, its time to get it more deepper hehe
EDIT: Now i can start the sshd daemon and try to login into with ssh BUT i can't change the sudo pass with passwd cuz says Not enough permisions. Also, i cant find the damn it sudo binary...
I have the USBNetwork working by default on eth0, but that's all i can do cuz i can't start too the bash.
Any hint?
Bye!

well those steps are similar to a regular arch install, what exactly is your problem? no sudo in package sources? can't run visudo? you have a root account, just use it instead of a user account for now
edit: can you start an own topic for linux on nexus? we really should leave paul's thread alone
Yes i think it too hehe Sorry enom
I have been using the latests builds to see if they mitigate a common problem in our devices (mine is a Polaris). The insufficient memory makes it lag until forever when switching amongst applications, not only the heavy ones, but also the supposed light applications like Messaging, Phone, Contacts, etc.
The system has to work under really hard conditions: 20 - 28 MB when starting up. Every application I run is a fire proof. Applications like Navigation makes our devices literally crawl and bite the dust. Not far away, I was driving and tried to play some music at the same time. It was impossible. The waiting was unbearable and it finally hung like a pro.
My question is: is there any chance to free up memory or use it more efficiently in order to avoid these undesirable situations?
Did polaris get back some memory with Froyo kernel like vogue did? From the video buffer or something... what res do you run at?
I'm running at 240x320 - 120 dpi
I made a screenshot of a "free" command in a terminal (see attachment image).
My kernel is this one (converted with Atools):
http://androidhtc.git.sourceforge.n...=2.6.32/VOGUIMG-320-FROYO-10-4-10.NBH;hb=HEAD
Thanks for your interest!
Im not sure.. but is there a way to use the sd as ram?
I think its not fast enough, but i havent seen any "benchmarks" yet how fast the ram on the polaris works.
Maby its slower but fast enough to work as swap etc?
Enabling compcache will help you.
Still, our little devices cannot multitask very well with Android, but I can navigate and play music at the same time, with compcache.
You will need drivers that match your kernel, in /system/lib/modules. I have packaged some in the first post of this thread that should work for each of the two popular kernel versions.

Thank you SuperJMN for this thread : I hope this help us for better use of our phone.
Like you, when I try to use my GPS navigation (Navigon or Igo8) I'm bored that's too slow !! Impossible to change anything if I want...
I try now with Compcache enable, I can see 130024 (total and 104156 used) instead of 104024 : swap = 26000
Cheers.

I installed this update for my .32 kernel (dated September, the 30th):
http://forum.xda-developers.com/attachment.php?attachmentid=409422&d=1285714954
My build is the latest: http://sourceforge.net/projects/androidhtc/files/system-froyo-01-10-10_16.tgz/download
When I open a terminal and type

compcache.sh enable
it states that compcache will be enable in 120 seconds.
After that time, a free command doesn't reveal any change.
I've also tried typing
su
compcache.sh start
When doing this, it processes the command and after 30 seconds or so, some lines are displayed:

By the way, the touchscreen behaves erratically with 4-oct NBH. Test with calibration app and tap the screen. You will notice abrupt lines.
Edit: if you want to see which behavior I'm referring to, watch this video: http://www.youtube.com/watch?v=DPLu41BUB1Y
It happened sometime in the past, but with this one it happens the same (although the abruptness is not as much as in this video).
Edit 2: Strangely enough, it is fixed on reboot, but after some time running the touchscreen starts to behave crappy again. It happens with the newest .NBHs made in October.
I have a Droid A855 rooted, CM7 installed. I have the latest build. I have two issues, one is that the free RAM is ridiculously low with like 5 apps open it has about 20MB of RAM free. This is unacceptable because my Huawei Ascend has 90 free with many apps open, and the Droid has twice the ram of the Ascend. Is there any suggestions about this? Also the camera was working great and then it started freezing, and now the camera force closes when I press the button to take a picture. If I go to the camcorder it works fine, but otherwise I get force close. Any help would be greatly appreciated.

Personally CM7 has just never ran smooth. No matter what I have tried. Gingerbread was never really meant for the Droid so most roms have built in stuff to help with memory that I do not believe CM7 ever had added. and the camera is outright terrible lately, I have it force closing on all my roms. I really don't know how to help all I can really try suggesting is trying out other roms

Thanks for the quick reply, I beg to differ on the Gingerbread not being for the droid part, my old Ascend runs Gingerbread Cm7 with flying colors, and this droid has double the performance...

I think you guys are missing a crucial part about how Android is built. Free RAM is wasted RAM.
Newer versions of Android, especially Gingerbread, are better at RAM management than older versions. Granted, there's an ever-growing need for more RAM for basic system functions, but Android is designed to free up RAM on-demand for the things that need it.
Just because RAM isn't free doesn't mean that the system is going to slow down. Android will put the stuff that's not being used anymore into a swap file so that the stuff you need to work with can do what it wants.

What? I dont understand
I agree with you and I will like to agree with you but it just won't work. This is like Windows Vista, they use all the memory, but it is very slow when you try to open application which you don't use a lot.. and it also causes a lot of slowness when you try to use more ram for soemthing else, like modify a huge image in photoshop and then switch to some other application.
Get back to the real story, my phone get memory lower than 50 free MB easily. and when I open Google current in this stage, it just hangs for 5 minutes. then I get a message "force closed". However, if I have 100 free MB, then I am safe, I don't see that popup message. Moreover, when I go to 40 free MB, I even have hard time to open skype and pick up the phone, it just rings, but the screen just hangs! when the screen refresh back, people get into mailbox already....
anyway, I found a software to temp solve this problem ZDbox. I set up when the screen hangs, "kill all apps in the memory" it is not best, but at least I can pick calls, I can run application without getting "force closed" message all the time.. because I need to reboot few times a day to solve ram issue.
perhaps, you can do a test yourself.
- install CM7
- install facebook app and run
- install google reader and run
- install google current and run
- install skype and run
- install gmail and run
- install google voice serach and run
- install google book and run
- install whatsapp and run
- install naver LINE and run
- install twitter and run
- install zdbox and run
- install lookout and run
- install go laucher
well after all this, your phone show be in less than free 50MB.. if so, try to run other application and you will see the problem.. screen hangs.....very slow response....not able to pick calls...

Yeah but even though "free ram is wasted ram" it still causes instability and force closes along with just pure out lag. My D1 lags when it has only 30mb of ram or less anything over 50 and it flies along. It lags to the point were even simple tasks are slow when they should not be.

Droid has 256MB RAM. (Actually, there's only 226MB RAM available to kernel.)
If the Droid has twice the RAM of your Huawei Ascend, then your Ascend has only 128MB RAM.
If it has 90MB RAM free with many apps open, then it means that all the system services and all the "many" open apps has to fit to 38MB of RAM.
That's hard to believe.
And btw., you can't compare RAM consumption on devices with different display resolution. Droid drives 854x480 pixels and uses hdpi bitmaps. I guess that the Ascend has lower resolution. The RAM demand is much higher on WVGA hdpi devices compared to low resolution HVGA/QVGA mdpi/ldpi devices.
When I my HTC Desire Z, I was in love, awe of the beautiful interface HTC Sense and the many adjustments I needed to make experience to a higher level, the Android. However, as I went about installing my wealth of applications, games and widgets (more than a hundred, are addictive), Sense started getting so instead of improving my experience. The initial screen would start every few hours re; each faucet took longer to record; Screen rotation when the keyboard sliding open continue for centuries; and each phone looked like he was struggling to get by.
Guys, I need a help. Tried everything, but still facing big lag especially when I click on dialer, contacts or messages (waiting couple of secs until they show up). This is more obvious when I click right after I 'woke up' my phone from deep sleep.
I'm using stock 20b with Iodak v8 kernel (tried v9 as well, but due to bluetooth and fm radio issue on stock, reverted to v8). Also, I did everything what I could found to improve performace: disabled and then deleted MLT, did a full wipe of everything (clean install), installed only apps that I need, turned off 3g, data and gps (only WiFi is on), installed Greenify and so on..
My current setup of kernel is following:
Governor: interactive (tried ondemand, but was even worst)
Max: 1600000
Min/Max Screen Off: 760000
Scheduler: SIO
CPUQuiet Power: userspace (noticed that only 3 cores are online instead of 4)
I appreciate any help, but please, don't tell me to search, 'cause I did. As for the other custom roms, I tried CM, but I prefer more stock, mostly because of Gallery, Polaris and FM Radio Apps.
Guys, is there any way to fix this lag issue? I don't care much for the battery, since this lag drives me crazy.
Thanks in advance.

This is "normal" for system apps. Download custom apps from google store like ExDialer,GOSms.. That will resolve your lag.. When you install those apps from store, use titanium backup to freeze stock apps(dialer,contacts,messages).

Thanks guys, but neither of these two options helped. There's some improvements, but still pretty much laggy.
Think I found out what causing lag: synchronization. Every time when phone is synchronizing, everything is so laggy, otherwise is ok. Following accounts have sync turned on: Skype, Facebook, WhatsApp, Twitter and Google.
Does anyone of you have experienced similar problem? Is there solution for this?

I have all those apps running in my phone, but I did not face those lags.
But ya I did felt those lags when I'm still using stock JB OS. Stock JB from LG is sucks man, you should instal another ROM.
Currently I'm using CM11 (Kitkat 4.4.2 based), its lag free and have more free RAM. (around 350 - 400MB). :good:
The difference is like heaven and hell compared with the stock ROM (I only have 150 - 200MB Free RAM).

The ROM can make a difference, but it has nothing to do with "Free RAM". I wish people would stop perpetuating this myth.
Free RAM is wasted memory on an Android device. Unless you are getting below about 50MB there is not a problem as the device is designed to use as much as it can and then swap it out automatically.
I agree about CM11 though. I'm running the latest nightly and the only problem I have is the delay in waking when you press the power button

I agree about CM11 though. I'm running the latest nightly and the only problem I have is the delay in waking when you press the power button

Well.. Sorry for my false statement and thank you for correcting it
4X HD is my very first android device. But that's what I really thought after I flashed the CM11.. Its like whoa, more free space on RAM, and it feels like I'm using a new phone

RAM: What it is, how it's used, and why you shouldn't care
Well, I’m afraid that I’ll be forced to get back to CM (used it once, but missed some apps such are: FM Radio, stock gallery app (couldn’t find good replacement that synced photos with google acc) and Polaris Office – these apps I use on a daily basis). Anyway, before install CM, I’ll give one more try to Stock.
I did what @ottomanhero told me, and that actually helped. But, since I used Trickstermod to tweak governors, after every single reboot, stock values would be back, so I had to use init.d script, and there comes a problem.
Here is what I did (followed instructions from Iodak's OP):
- Using ES File Explorer created folder /system/etc/init.d and set permissions to rwxr-xr-x
- Created new file in init.d folder and name it 1script (used Note++ instead of Windows editors to avoid leaving an extra space at the end of each line or an invisible invalid character)
- Then added following commands:
Code:
#!/system/bin/sh
echo "70" > /sys/devices/system/cpu/cpufreq/interactive/go_maxspeed_load
echo "70" > /sys/devices/system/cpu/cpufreq/interactive/midrange_go_maxspeed_load
echo "60000" > /sys/devices/system/cpu/cpufreq/interactive/min_sample_time
echo "20000" > /sys/devices/system/cpu/cpufreq/interactive/timer_rate
echo 200 300 400 450 500 600 > /sys/devices/system/cpu/cpu0/cpufreq/gpu_overclock
- and finally set permissions to 1script rwxr-xr-x and owner to root group to shell
So, that should be it, but didn’t work for me. Then, I installed SManager to check what’s wrong with the script, and it stated that with first 4 lines error is: no such file or directory (which is strange because exactly that's the path), and for the last line is stated: permission denied.
Did I miss something? Apologize if this question is too noob for you guys, but I’m running out of ideas.
Thanks all for your help.

Vladimir

Oh, really?
Free RAM is NOT wasted RAM.
It directly effects smoothness of the phone.Why do you think android would have Out Of Memory values if it was created to just fill up the RAM with only apps? It still needs some RAM free for caching.

I think the script didn't execute at boot due to last line, you forgot the quotes.And while using Smanager you gotta tick "root" or else it won't run.Try this one

Well, you were right about the quotes (now, the new values are set), but as the other 4 lines, they still have the same error: No such file or directory, and all values are stock.
Do you have any idea what's going on? Why did it work for one, and didn't for the other lines?

Of course you need some free memory, but not hundreds of MBs of it. I notice that you pointed the same XDA quote that is used and linked to by lots of different sites when this is being discussed. To use someone else's quote - better written than I could do so myself;-
In the most simplistic terms, here is how it works, and why "free RAM is wasted RAM," but also, why you don't want all RAM in use at any given time.
If an application is not in memory when you try to open it, that application haa to be loaded into memory, thus triggering a "load time." Having the application in memory (prefetched) prevents this load time and has the application load near insantly. This is why a modern OS will preload our most commonly used applications into memory. The more memory that you have, the more applications that can be preloaded, the smoother your device will run. Clearing this memory gives you no immeidate benefit, and will actually slow your device. Idle applications in memory consume almost no resources (CPU cycles, battery power, etc.). If an application is consuming resources, that means that it is doing something. Closing it will only force the application to re-load. Using a task killer for this purpose will cause a "boxing match" where the task killer closes the application, the app reopens itself, and back and forth. THIS will consume resources.
However, you want to have some memory free. Your devices will not have enough memory to preload EVERY application, so it has to guess based on your actions. It needs to have enough memory available to quickly load an app that you may want.
Let's say that you want to load an application that requires 256MB of RAM, but you only have 128MB available. This means that the OS is going to try to clear 128MB of RAM to accomodate your app, and as your app loads, will try to clear another 128MB to return to its previous state. This clear/load/clear causes a longer load time and more slowdown than just loading an app not already in memory.
So, the ideal situation is to have most common apps in memory (pre-fetched), but enough memory available to handle 1-2 common apps that are not already pre-loaded. Touchwiz (Samsung) devices allow you to clear memory from the task manager. My S2 had about 870MB of user-available RAM, and if I trashed all apps, it would go as low as 300MB in use. This may look cool, but it is a complete waste of resources, and the OS is simply going to re-load those apps over the next 2-3 minutes anyway. And if you use a task killer to keep your device idling at 300MB of available RAM? This is simply going to slow down the device, harm the battery, and give you the same memory performance and availability that you would get with an HTC G1.

As the OP was stating that "I only have 150 - 200MB Free RAM" with the Stock ROM, that is definitely NOT what is causing a lag issue. If you have that much free memory (before Android goes caching stuff and not declaring it of course) then you are absolutely fine on any Android device there is.

Maybe your partitions aren't mounted.I took these lines from pimp my rom init.d script.Create another script but it has to come before the governor tweaks script.
#!/system/bin/sh
busybox mount -o remount,noatime,noauto_da_alloc,nodiratime,barrier =0,nobh /system
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodir atime,barrier=0,nobh /data
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodir atime,barrier=0,nobh /cache

For example, name this script "93Mount" and name the governor script "94Governor" so the mounting script will be executed before governor script.

Well, I did like you said and here's what I got:

failed: No such file or directory
failed: No such file or directorybh on /data
mount: mounting atime,barrier=0,nobh on /cache failed: Invalid argument
Any idea?
For the People who want Stock Gallery on CM and hate Aosp Gallery like Iam, check facebook offical cyanogenmod. They send a link to their new gallery next. Its in beta stase, so its not avaible yet. But if its stable itll be in play store. Its like the stock gallery app. Very beauty

Well try this app https://play.google.com/store/apps/details?id=com.stericson.remount&hl=tr
EDIT : check this link out. http://forum.xda-developers.com/showthread.php?t=1381188
I'm not sure it's the right track or not, it does happen to me quite ago.
The problem is the SD (my case, luckily it's external). The system try to read files from card but it got error thus try again => laggy
I removed the card and it's alive. Try to check your internal sd. hope that help
App didn't help, I got the same error. Never mind, I give up Will use Trickstermod after every single reboot until finally find solution. Thanks @ottomanhero for all your help.
@GalaxyVolvoZ that app looks realy nice. Finally a good replacement for Stock Gallery.
@klbterminator I don't have any problems with SD, at least didn't so far
Thanks guys.

Hello fellow MI5 users,
I received my phone one week ago and I start having some issues with the RAM. In fact, at the start of the phone, it's already at 70% filled up which is too much for me. Indeed I use a lot of RAM and I'm that type of guy who let the apps running in background everytime because I keep opening them everytime. I was wondering if it was possible to have a link to a better ROM because I guess it's the problem and also a link for a tutorial on how to flash it I'm a newbie in this type of manipulation but I'm very interested so I hope you will help me guys. By the way, my MIUI version is the MIUI 8 Global 6.8.18. I honestly don't know what can i give as information but I'll answer ASAP at any questions
Have a good day
This is working as design - Android keeps apps in RAM to reduce I/O on resuming from background - faster & more energy efficient.
You can change the number of background processes via the development settings or you can kill apps on closing.

I've seen that indeed but it was set at standard so I'll probably put it at 3 I guess. How should I set the memory optimization? I've read it should be set off, altough I tried middle and I feel comfortable like that?
Is it normal to start at 70% without anything started ?

For the 3GB version? Pretty much. MIUI is horrible.
After booting I typically had 1.3GB / 3.0GB free but after a while this averaged to around 650MB free.
free ram is useless ram , which cant accelerate anything

I know that but I need more because I use multi-task a lot. Is there a way to change the ROM so I have more space to work with? Even if the ROM itself is beautiful.
Indeed it's the 3gb version 32gb. It have lags sometimes and I think it's due to the full RAM. Can I have a link to a custom ROM which works fine on this device?
I'm a little confused, you want as much RAM available but you want as many processes in the background as well? That sounds contradicting to me. Memory optimization maps to ZRAM, if you set it off there will be no memory compression and thus even less processes will be kept in the background. If you set it high, you can have as many processes as possible, but there could be lag due to (de)compression time overhead.
Try different Rom
Try to use a different Rom. On the Stock Rom is a lot of bloatware which is using your RAM too.
First you need to get an Bootloader unlock permission and have to unlock the BL.
It could take up to 10 Days to get the permission from Xiaomi
http://forum.xda-developers.com/mi-5/how-to/unlocking-xiaomi-mi-5-bootloader-t3336243
After that you have to flash a recovery like trwp via ADB. Google it for videos or threads how to do it.
http://forum.xda-developers.com/mi-5/development/recovery-twrp-xiaomi-mi-5-t3412123
After that you can flash a developer Rom.
I use the Resurrection Remix and it works fine. The CM 13 stucks in Bootloop. Maybe because I made a full wipe and had to sideload my rom.
Because you don't have a SD card option you have to have the room installed on your hard drive. But just follow the description below
http://forum.xda-developers.com/mi-5/development/unofficial-resurrection-remix-m-5-6-9-t3395945
It took me just 1 day to get the unlock permit but don't try do do it without it. You brick your phone.
The RR Rom works really fine. Fingerprint and everything. It has no bloatware and you have to get the gaps like in the description. Arm64 nano seems enough.
Good luck and fun with a great phone.
Normally the android system kills the unused apps even in background. But i also experienced lack in multitasking.

I think you misunderstood the OP question, he wanted more free RAM at start in order to have as many as possible apps in the background.

Yup exactly
Try trwp 3.0.2.0 with 3.0.2.1 people experience bootloop

In fact, I'm just doing some research before asking because I'm very new. I have found some videos but they are pretty old and not on this phone but I guess it works more or less the same way

OK, in that case, just open Security->Permissions->Autostart and disable those which aren't immediately needed upon start. I have 18 autostart items (mostly system monitoring & social media apps) and I usually start with 1.5 GB free RAM.
