Managing Memory

Hi all,
One habit I've developed with the Captivate is using Advanced Task Killer to kill apps that otherwise would just be hanging out in memory. I do this probably because I'm anal retentive like that, but also with the thought that it save me battery life if I do.
This has led to two questions of mine (excuse the noobiness to Android if these have been discussed):
1.) Why do so many applications start automatically when the phone boots up? (browser, gallery, etc etc). Is there a startup ini somewhere I can edit to prevent this or do all the apps just wake up? It's easy enough to kill, but I find some of the apps that start up very odd.
2.) Over the course of the day, even with Autokill on and security set to "Low", eventually my memory is consumed and it only gets back to its full state until the phone is rebooted. After all obvious apps have been killed the memory usage will will go from ~170mb (after a reboot) to as low as ~130mb (at the end of the day). Does anyone know why that happens and if there is a better way to manage memory/apps?
Thanks.

I used to use task killers, but I have uninstalled them and just let android do its thing. The only reason I'll end a program is if the program has an exit function or has froze, which is rare. With this method I don't have any slowdowns and great battery life. On the flipside I don't install poorly developed apps. Thats just me though.

Open apps slowing it down

I was always of the impression that open apps on android don't use up power etc.So I have never had task killers on my phone or tablet but recently I have noticed after about half a day of the tablet being used on and off by me and the kids its slow down quite a lot but a reboot and its back to normal.so is it open apps causing this?

yes and no. A process may be slowing it down, but it might not have to do with apps. One way to check what apps are running is by going into settings, press applications and press the tab that says "running" and see what is there. If there is a process that is burning too much memory or processing power, then kill it (don't kill too many processes though because some are important for running the underlying os). And, if the app keeps slowing you down, then concider uninstalling it.

Still getting this problem after a couple of. Hours use the tablet is slowing down

Use Advanced task killer from the market. I usually just press the recent apps button (right of the home button) and close unwanted apps ... not sure its thats a feature of Revolver rom or not though.
Android does use apps better than windows etc but if they have been ran they still resrve memory (not so much CPU) but sometims this can mount up enough to slow your device down.

H81010o issues

I ended up getting the latest ATT/LG software update, build LMY47D / H81010o. It actually let me choose when to install it so I'm happy about that, but I'm having a few problems. The screen seems to be working better now, taps, touches, swipes, and drags seem to be working correctly - but my phone is running really hot - even after a couple reboots. and for some reason all of my task killers no longer work. I use CCleaner and AVG to flush out ram because even though the G4 has 3gb, about 1.6gb is always in use with factory apps only. None of the task killers detect any running apps now, even the built-in LG task killer doesn't find anything running in the background.
Anyone else having issues with task killers? I've cleared the cache out of them, dumped the data, re-installed them, and they still don't work. I had a few other apps that quit working but once I dumped the cache they started to work again. Also, the phone seems to boot a little quicker and charge faster too, seems like mixed results with the latest upgrade.

Everything I've EVER read about task killers says that they don't really help because they are at odds with Android. And RAM is supposed to be used. Android will drop things out of RAM if it needs more.
The issues with memory leaking are inherent to Lollypop and are "supposedly" addressed in Marshmallow. We'll see.
But I had the same issues with my S6 and S6 Active.

Task killers shouldn't be used with anything later than Gingerbread. They simply serve no purpose. Android's stock RAM management keeps everything how it needs to be run, and shouldn't be messed with. For example, every time you go and use one of those task killers to flush out your RAM, Android is going to turn around and load those same apps right back into RAM because they're set with certain OOM values that tell Android when to kill them off or when to let them stay in memory.
So, in practice a task killer is probably robbing you of battery power.
The only thing I still don't like about LG's software is that they HAVE tweaked the stock RAM management system that Lollipop uses to favor keeping things in RAM for longer... and things on the G4 can get a little slow sometimes because of it. Just use the app switcher and swipe them away though, that way the app services can still run in the background like they're supposed to.
The G4 would be my ideal Android device if they would ship it with stock Android and just put their apps on top of that. RAM management doesn't need to be messed with, and UI elements don't need messed with (lollipop is quite elegant).
As for the "o" version, I was forced into it. It never asked. It installed itself while my phone was laying on the coffee table. Really pisses me off.

It isn't able to hold GPS tracking app in background; help me please

Hi, I have a problem with RAM management, or keeping an app running in the background to be more specific. I'm running stock EMUI 4.1.
If I have too many apps opened and stored in RAM (like 5+ or so; such as fb, messenger, email, youtube, instagram, ...), it often causes restart of the apps while switching between these apps I have already opened and stored in RAM. Even if it shows I have 1,5 GB RAM free. What's the point in high RAM capacity in phones (3-6 GB thesedays) when even with that much RAM (and that much FREE RAM) the phone isn't able to hold them really "opened" in RAM all and the apps "reloads" (as if it was launched for the first time) when you try to recall/launch them (quickly, but still).
It doesn't bother me that much generally, but only with one app - GPS tracking apps. After some time (maybe 1-2 hours) it always "drops" the app from RAM (it's still in recent apps though) therefore deleting my existing workout and tracked route. It's annoying. And yes I have the tracking apps selected in "protected apps". It happens still. Once I rebooted the phone, cleared apps stored in RAM so the only app running was Runkeeper. I went cycling and after some time (1-2 hours) I stopped, took the phone out of pocket, turned the display on, clicked on the GPS tracking app and it started to reopen/reload itself and once it reopens -> no trace of my existing workout, everything was gone. All of that with ~2.2 GB of free RAM.
What good does 2.2 GB of "free RAM" do when the phone isn't able to keep the only running app in the background for few hours? I tried many GPS tracking apps, happens always. It didn't happen with my Moto G (1st gen.; 2013) with 1 GB of RAM, but it happens with a lot newer and better phone with 4 GB of RAM?
Any tips for that, anyone? Please?

Don't know if this will help or not. Had a similar issue with a music player app. Gave it permission access for 'Phone'. Did not happen again till now. You can try that out.
You can also try Setting>Apps>Settings>Special Access>Ignore Battery Optimization>'Your App'>Allow

Weird changes in terms of speed

I've had my U11 (64/4 variant) for a month now. I'm satisfied with it in general, but I've noticed something really peculiar.
In the first days, my U11 was extremely snappy and fast (opening applications, opening the camera, unlocking the screen, and so forth). However, after using it for a week, I noticed a strange phenomenon: the general speed of my phone was changing all the time. I mean, sometimes, I had to wait approximately 2 seconds for Gmail to load & display my inbox, while sometimes I just tapped on Gmail and it loaded & displayed my inbox almost instantly. (No, Gmail wasn't in the RAM in the latter case...)
It's still happening and I'm not happy about it because I ditched my S7 due to Samsung's tacky and laggy TouchWiz (I heard that it had been renamed, but I don't really care). Don't get me wrong: I'm not saying that SenseUI is laggy and tacky because I love it and I haven't even experienced a slight lag since I had this phone, but the unpredictable speed of my phone is irritating a little bit. By the way, the same goes for the camera (stock application): sometimes, it takes quite long for the camera to load & be ready, while sometimes it doesn't even take a second.
More than 90% of the storage is free and more than 50% of the RAM is free most of the time.
What do I do? Shall I perform a factory reset? As I've mentioned, I'm using the stock ROM and I want to do so in the future, too as I've got used to it.

Htc Boost+ app. If you dont have it get it. If you do have it then check the foreground and background restrictions.
If you're using any apps from 3rd parties that control apps and ram, remove them. Android has it's own app killer and boost+ will do the rest according to how you use the phone.
Signal clarity is also a huge player in the speed of today's devices. If you have a weak wifi or cell signal then the phone has to wait for the data transfer so server connections will suffer, hence why you experience intermittent slow loading.
The camera may take a while because of not being in background or if other apps are consuming resources. Also the more you use an app the quicker it should open as android 'should' hold the app in ram, if theres enough room.
Hope this helps clarify.

Thanks for your reply. I had already used the Boost+ before I posted this thread. I deleted a few apps that I hadn't really used, and now I don't have any problems with my phone as far as speed is concerned.
