Most probably widgets have nothing to do with lag, but the feed widget and some weather widget will drain you battery faster since they must be syncing a lot.
Normaly free ram is low most of times, because Android put apps there to load them faster when you need them, but running processes will in fact affect your phone performace, check out if there is anything running that you don't need and close it.
Just recently, I changed from custom roms to stock roms, and I think stock roms are a little more responsive.

I have like 5 or 6 apps installed and free memory is curently on 129mb.
Running stock JVT.
You should try your apps and keep only the ones you need or use, anything else will just slow down your phone (and drain battery)

Try using advanced task killer pro. In setting set kill mode to crazy. It automatically kills unused apps on screen lock.
Android starts to lag if RAM falls below 50MB. So, you should try removing some apps.

Android. Is. Not. Windows.
Android kills apps when it needs memory. If it doesn't need memory, it does not kill apps; if you do, it will relaunch apps—this is because it is more efficient to have apps cached in memory for when you want to use them, as opposed to relaunching the app every time you need it.
Killing apps does one thing: it causes the Android system to utilize free RAM by launching more apps. Doing so takes processing power, and does nothing but drain your battery.

I've read this to be true, task killers are not a good idea on android, it is better to delete unused apps, or have them backed up with titanium in case you need them.

why shud i uninstall apps even if they r not running in background?
and why when i click the home button while am on an app the app closes instead of staying in background

And am on jvs now shud i update to jvt ??

Because Android decided that app needed to be closed in order to reclaim memory for other purposes. If you're unhappy with the way Android manages your RAM, there are various options available to tweak it. Adjusting the amount of RAM the system keeps free will allow for better multi-tasking.

I'm on JVT and it feels like better than JVS to me.
Slight differences:
You'll have overscroll effect as default
My battery seems to last a LOT longer (at least for me on stock rom)

[Q] RAM Manager app to prevent redraws

Hi,
This is sort of a continuation to a thread I made a few weeks ago, which was about launcher redraw problems I had with every single launcher I tried. I'm on FroyoPro v2.5, and on the recommendation of a fellow board member (thanks, Dagger) I'm running Nemus launcher. Basically, whenever i install or uninstall an app, my launcher prompts me to either force close or wait, and when I choose wait, it becomes slow for the next five or ten seconds and then returns to normal. It was worse before, but ticking "Lock launcher into memory" solved the most of the problems. Seems that the lack of RAM was actually the source of the problem.
I was recommended the SuperCharger script. However, I needed a newer version of BusyBox to install it, so I scrapped the idea for the fear I might brick the phone.
I investigated further for a solution, and found the app called RAM Manager (free version), which was made by a developer here at XDA. I installed it, set the "balanced" profile, and it actually fixed the problem. No redraws so far, and I even think the launcher is a tad smoother than before.
Has anyone tried this app? Is it a good thing to have or would you rather recommend I try something else? Are there any apps like it that are perhaps more efficient? It seems that all I need is better RAM management for the issue to be solved.
EDIT: Forgot to add the link to the XDA thread: http://forum.xda-developers.com/showthread.php?t=1305060
So far so good. Battery seems more or less unaffected. No negative effects on AnTuTu and Quadrant benchmark scores. Played five games in total, seemingly no negative or positive effects. What are your feedbacks on this?

The ram manager is actually a substitute to the supercharger script.
I personally recommend it if you are having ram issues.
Also you may freeze or uninstall the useless apps(mainly system apps) so as to free more memory.

Hm, now two days into the testing I've noticed that launcher redraws still do happen on occasion. However, it also seems that this app does the job well the moment it started and several minutes after running, but its effectiveness sort of degrades afterwards. Two days after I don't even notice any difference than before. What's the reason behind this? Is it fully compatible with CM ROMs?
There's only one more thing that I would also like to try before dropping this whole issue completely. Obviously it's a RAM thing, because running the backup I made a day after flashing FroyoPro seems to have no problems until I choke it with more apps. Then the same thing starts occurring. Not much can be done with the limited RAM X8 has.
However, what do you think about tweaking the VM heap size and MinFree values in CM settings? Is it possible to alleviate the problem with some tweaks from there?

Ahhhhhhh
V6 supercharger is just a ....beep.....
Before using that my antutu benchmark was 4005 - after installing script my score had a freefall @ ~3500~ ( lost 500 scores)
I'm using ram manager pro too, I can say that its awesome for setting to -multitasking option ( 3 apps at the same time)

Yes, and I might actually try buying this app. Even though it didn't resolve the redraw issue completely, the general feeling of better performance seems to linger. I'm going to keep running the free version for a few more days and see what would happen

There you go...
Download "system tuner pro" or any similar apps from market.
Press "tweak " button
Set "hidden apps" option to maximum value (now its 24mb but u can raise it to 32 or higher )
That's it...
*launcher pro OR adw launcher are too light and don't need to increase memory (I use adw with Widgets without reddraws

Use thishttp://forum.xda-developers.com/showthread.php?t=1987032
It works for me.
Just install the apk and tick both yes and run at boot.

Ram Usage and Lag

Hi People, I have my 8.4 LTE Exynos for 2 weeks now. I rooted it on the second day, debloated/frozen unnecessary apps. However, my RAM still uses up to 2.4gb which leaves me 300mb free.
Im noticing lags while playing SimCity, Deadtrigger2 and more. What annoys me is the FB Messenger lag.
Just want to know if any of you experience the same. I bought this tablet because of 3gb ram so that i can still install dozens of apps without lagging.
also, im using appsetting from xposed to keep hangouts, phone, contacts and Nova launcher in memory/keep resident, however when i open phone and hangouts, it seems that they are not in memory since it takes 2 seconds to load/display in the screen.

Actually mine doesn't lag when playing any high graphics games except that it just drains the battery faster than a hot potato.
If you are using a different launcher I suggest you disable touchwiz at it is resident and eats up memory however you will lose the ability to multiwindow and other features.
Also download greenify and enable its exposed mode to hide apps in the background to save memory
Clear dalvik cache to zipalign your apps.
And by default my system apps stay resident in my memory. Check if you have a firmware update

I've never experienced such thing. Are you using CM 12? That's too much ram used.
Could you show us your running apps? Without games

Stock android, debloated usibg debloater. 1.25 gb ram in use, never hit anything higher then 1.9.

Lollipop dropping as I type, report back when you get it

im using stock. ill be posting the screen shot in a bit since im charging my tablet. what i remember is that upon viewing task manager from rom manager app, i see all apps in the background. and they're eating my ram.

well then use nova launcher and set it as your default launcher but TW will run in the background so expect some RAM eating

RAM Hog?

I just got mine today and have a minimum of apps installed. I hope this isn't normal RAM usage. Also, what is the icon next to the 4G LTE icon?

Don't worry about RAM. Android will automatically expand and contract the space available for applications in the background without worry. Think about it like this:
You have 50 processes/applications running taking up 500MB of RAM allotted to 10MB per process. When you have to utilize say one of those processes and it needs 150mb of ram to run properly your device has to call that process, expand that process and then contract it once your done using it. (or the system is done using it). That takes unnecessary battery and time.
What Android does is let that application/process that needs 150MB of RAM to run, have it if there isn't an issue (maxing available ram) so when it is needed it doesnt have to expand and contract. When you open a large app or game and it needs more then is available the system will automatically close down and slim RAM usage, but only when it is needed.
What does this mean to you? 99% of the time you will NEVER notice that 80%+ of your RAM is being used. But if you start closing or restricting applications to small sizes (trying to keep RAM usage to a minimum) you will absolutely notice it as it takes more time to load up things like recent applications, respond to a home button press or open an application.

That is the NFC icon. It means you have NFC turned on.

if you want a fast, smooth, lighting response phone, it will use up tons of RAM. You dont 'need to care about ram use unless you run out of it completely and notice lag. as long as the phone is not lagging then you don't need to check ram at all, it's high usage is necessary for a fast smooth phone.

All cores are at 100% every few minutes

Anyone knows how to see which app is using the most CPU time? I want to throw my new redmi note 9 at the wall already. Hardly any apps installed and every few minutes it freezes and becomes unresponsive.
I got one app and it showed this during freezes

Did you install a new app before that started?

No, Even during initial setup it was like this

Do you have root right now ?
Basically the miui doesn't kill the app when you close/ leave it.Download something like avast cleaner in the Playstore and close/force the apps listed.Hate to say it but don't expect wonderful things from this phone.Mtk cpu and the biggest problem the miui interface atm.

Can I leave it unrooted?
I checked battery stats and it says 75% is taken by screen time. Is there any app that works without rooting and can show the tasks occupying CPU time?

Mmm let me see what ROM are you on global,EU, and what version.
This phone especially some roms are famous for a heavy load off bloatware,ads,tracking, collection off data.mix that with a very in my opinion really bad miui software.
Because you're screen takes the most battery drain most likely we could rule out a third party app.leaves us with system apps.
I had the same as you're phone out off the box freezes.
I debloat my phone installed a alternative launcher with addquard.its not a rocket but it's most off the time ok only use it as back up.
Basically I can't think off a very easy way to get detailed information right now.Even you have root system dump log .even then you have a load off info.system tracing is available but takes time to learn and understand.

I'm on global rom, 12.0.6.
I thought chrome was the problem and disabled it but I still have these 100% cpu spikes every few minutes.

Global ROM is not the cleanest ROM out there.i am not at home right now so I can't check on my other phone if we can get some information out of a non rooted phone.
I would like to point out this page.
Saki EU tool Szaki used it on global 12.03
You don't need root just read the page and run.chrome is no light weight but a mi browser with adds and tracking is no joy either.

Well because I did use this phone only for work.Testing,sharing I only do in emulators.So dropped in the phone with my son to kill it basically what we found out.its not the CPU it is android 10 what request around 2gb of ram ideally.So we got 1gb left normal it should kill processing apps if it runs out of memory.
Now the mi shell miui is holding on 2,2 GB if you play games like asphalt 8,9 zombie hunter,armor god,af arena it is killing itself.
Disable miui or/and give the miui a order to automatically close apps he really don't like that.
So the CPU runs at 100% because off the shortage in memory so in theory we only have 2gb of ram.A android 10 runs idle already around 1,6 gb.So it's no wonder why it lags big
time on a lot.
The fix create a swap file on you're android device.ram expended root ,swapper root,link2sd with gapps root.there is a APK available what create a swap file on you're sd card ,take a good card do.no root.
A video to give you idea how it can run with an without a 3 GB swap file.Even with a 1gb swap file you should walk out the woods

1 to 8 minutes testing 4 games
8 to 11 minutes FPS test .
Last part starting without v memory stuck at boot screen.
