Hi,
We all knew that we should not use task killer to kill apps, because when we hit the back button, the app will not active anymore ... but it will still occupy some memory (RAM).
When Android OS needs more RAM it will remove in-active apps to free some.
Related article: http://geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/ (GOOD READ)
We should not panic when we see a huge list of apps when we start task killer.
Ok, got it there ...
Now, I installed this app called Quick System Info (FREE):
http://www.cyrket.com/p/android/org.uguess.android.sysinfo/
Which you can use to see what kind of processes are still running or apps that are still occupying RAM. It could show you the amount of RAM and CPU resources that are being used by each app.
So, I went to the Quick System Info -> Processes, hit the "menu" button -> Preferences and set like this:
- Update Speed = Low
- Show Memory Usage [checked]
- Show CPU Usage [checked]
- Sort by = CPU Usage
- Direction = Descending
Go back and watch ...
Surprisingly, I saw "Market" app is eating 1% CPU resources once in a while ... again and again ...
Hey, I thought it (Market app) is suspended in the background? I don't have it active, I pressed the back button when I finished with it.
Why is it eating 1% CPU from now an then in the background?
Obviously, this will drain battery power for something that I don't need.
Any thought?
I am now wondering if I install other kind of process monitoring app, and see if the suspended Quick System Info is also eating CPU resources
Why should we not use task killers? I`ve used them on android for the last year otherwise like you say background tasks use resources slowing up the system.
Obviously dont close any system important apps but I`m always closing down background apps that I no longer require.
1% every now and again? I really wouldn't worry about that to be perfectly honest. The impact on battery life will be incredibly small, so much so I doubt you'd even notice if you weren't watching it like a hawk.
By far the biggest drain on battery life remains all of the wireless stuff (wifi, bluetooth and 3G internet) followed closely by the screen itself. Turn those off when not in use and the miniscule drain of suspended tasks won't be an issue.
I'm sure if Google thought suspended tasks would be an important factor in battery drain they would've designed it differently to start with.

It does every minute or so, and so far I found only this app (Market).
I just found out this morning before went to work, so I don't have time to inspect more.
Too bad I cannot see CPU TIME (the amount of time the process took 100% of cpu resources).

that 1% would be it occasionally checking in with the market to see if any updates have been released for the programs you have installed, so that it can give you a notification when the update is released.
i would imagine that is what it is anyway.
and yes, 1% every so often is negligible, and if you killed just that process, i doubt you would notice any difference.

I am not sure about this..
Have you noticed that you will get a notification if there is an update to application that is installed in your phone?
I think the marketplace doesn't have a push notification yet. So it periodically will check whether there is any update to the installed application.
Allright, that might be it ... the Market is checking for apps aupdate.
And most probably 1% is not much (I don't know how to measure this and translate it to battery life time). 1% every minute ... hmmm
1 hour of 1% cpu per minute = X % of battery life.
If we have N processes?
N = email check, weather check, friendstream check, RSS check, whatnot check
I`ll give you an example why I use a task killer.
Sometimes I use an app that goes online every few minutes and notifies me of any updates. I can 100% be certain this app even when in the background uses enough cpu to cause the phone to slowdown. Dont ask me why, maybe bad programming but this is the exact reason why I need a task killer to get rid of it.
Once its gone the phone is fine again. it happends on a few apps I own, so when I finish with them, I kill them.
I wouldnt recommend a task killer that kills everything, you just need to be selective.
That is a perfect example for using task killer
What I wrote in the first post is about using task killer to just kill apps without knowing anything.
In the past, I just select all and KILL ... Then the HTC Sense got reloaded
I was scared it could corrupt my phone ... lol.

Yes thats a bit extreme killing everything.
I`ve also used startup auditor in the past. That stops some apps loading at startup , for example footprints, never use it so I kill it before it gets a chance to load up. Have to be careful what you limit though as some tasks are used by others.
That Startup Auditor is interesting, does it work as expected?
Or you encountered some quirks or issues with it?
Yeah, I don't quite like with the way Android startup (or HTC?), for example: FM radio ... it also started automatically after reboot.

Seems to work fine, not sure what help it is though hehe, in terms of speed/memory savings. I stop the radio , bluetooth,google talk and footprints. But I also use it to start some apps automatically.
I found this list of what you can/can`t disable. You can still run them after startup, just they wont load automatically when you start the phone.

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.
Phone is the 6GB RAM 64 GB storage version.
For the last couple of weeks it slowed down to a crawl when it comes to launching apps. For instance it takes 18 seconds!, I timed it, to open Skype on my phone. Other apps also open very slowly. Once they are opened and kept in memory they are re-opened instantaneously so the problem is only when launching the apps the first time.
There is about 2.8GB RAM available, only 35% of storage space is used so there is no reason why the phone should run so slowly.
I have upgraded to Oxygen 5.0.4 but no change.
If I run it in safe mode I can't check if it's slow or not because no user apps are available.
I have cleared Cache and Dalvik cache repeatedly to no avail.
Any ideas would be appreciated.
Does this also happen on newly installed apps? It could have something to do with the ART optimisations on app launch but you experience it every time you open it from scratch?
1. your phone is fake or defective
2. you have installed some battery saver apps
3. you have flashed some custom kernels
I have used OP5T for over a month and I have to say, it's the fastest phone ever I have till now, before OP5T I got S7E, NoteFE, Mate 9 and IMO Mate 9 is really fast with Kirin 960 but OP5T is better and smoother than Mate 9 in many aspects. The things I missed so much from Mate9 are Sdcard and extremely long battery, the rest are fine for me on OP5T.
SOLVED.
It was an application called ProtectMyPrivacy, PMP for short. If I don't start it after rebooting for some strange reason it slows the phone down incredibly. It's a very useful application, it blocks all the sleazy apps form accessing, unbeknownst to the user, things like Phone Unique ID, Contacts reading, Calendar reading, Fine Grained Location, Mac address, etc. It's crazy how bundled apps we aren't even aware run in the background collecting all sorts of information and sending them to who knows where. Apps like AdMob, Flurry, AppBrain, AppsFlyer, InmobiFabric, Hockey App, etc. that are part of a regular app that we download but we have no idea they are bundled in. Sleazebags.
Anyway, PMP blocks all these bastards from spying on the phone but I need to start PMP manually every time I reboot the phone. I sent an message to the developer, SynergyLabs at Cornegie University, to let them know about the issue.
I noticed there was a lot of dropped frame rates while playing PUBG. So i quit and shut down all the apps. Ran the optimiser and to my surprise I was not able to get more than 700mb. I ran the optimiser few times. But to no use.
Do you know why this happens? This happens quite often now. The max i get is 748Mb.
I have battery saver mode on at all times that reduces background processes. I also put loads of apps to sleep in the settings. I have Sync switched off. The biggest application i have is PUBG. I do not have any crazy mods or apps that might need certain permissions.
I have nova launcher and i have just added fluid nav with ADB settings.
I have the usual apps like WhatsApp Instagram Skype Twitter YouTube and NO Facebook or messenger.
This started only after the ADB mod. But I don't think it causes this.
I restarted my phone and got back upto 1.3GB but it goes down in few hours.
Any suggestions? I will provide more info if needed. I tried providing as much as possible

Hi to everyone. I'm comming from OnePlus 5t and I don't have any experience with "Ram boost" that we have on Oneplus 7t (Settings/System)... Also I didn't find many explanations by searching (neither here on XDA nor at Google search).
So basically, how it work and is there any benefit except gaming, (and I don't use mobile for gaiming) in real life?
I can't recall is it On or Off by default?
And last but not least, how it's effect battery life?
Thank you.
From what I read, it works like windows superfetch.
When ram usage is not taxed, it will fill the free ram with apps it knows you use frequently. Presumably as with windows, it keeps them in an off state, but when you open the app, it doesn't need to load it in to ram from flash storage, so it can load much much quicker.
There won't be any battery drain.
When ram usage is needed by say a game, it'll kick these auto cached apps out.
I've been using the OP7T for close to a month. I've experienced lag while using various apps, and especially when switching between apps. Occasionally the system becomes temporarily unresponsive, and a handful of apps have crashed multiple times. My previous OP3 phone rarely lagged, even if I had tens of apps open. I've been using the RAM booster on the 7T, but today I spent some time removing and freezing apps that were consuming tens of MB of memory in the background.
personally I didn't had any glitch or lag... I didn't saw any different.
But I don't recall is it turned on or off by default.
Anyway thank you both for comments and making it more clear to.
