[Q] Galaxy Note RAM clearing and overheating.

Hi. Im a noob i know. I checked the forums. But i did not find what i was looking for.
So. Its really annoying, everytime i clear my ram then in less than 15 seconds its full again. Which drains my battery and takes ages to charge. With this i get overheating. My battery heats ut self up to 60c° and the screen is nearly untouchable as it burns. I use a fan and it cools it down to 33c°. Any help?

Use this or this & block unnecessary apps frm loading during boot time..which rom u r using & which kernel?

are you rooted? if not the do that first and install titanium and remove u wanted apps

Rom
I have the latest rocketrom and hydracore kernel

May be do a full format and flash the rom again.

Full ram isn't always wasted. Its not like a windows pc.

yes. But it drains my battery and makes my phone really hot. Ill maybe just have to go and look for software thatll stop my apps from restarting as soon as i clear RAM. Thanks for help though

no, that's wrong. Clearing the RAM and forcing all the apps to load from scratch is heating the phone and wasting the battery!
The heat is generated by the CPU and the WiFi chip, NOT the RAM!
Android (and most Unix systems) use all available RAM to run more efficiently. It's not a power waste due to using the RAM in a very different way to Windows systems. I can't remember where I read it now, but an Android developer (either at Google or elsewhere) explains this better than me, but this is the general summary.
Short version: DO NOT USE RAM CLEANERS, Android is MEANT to use all available RAM, the CPU is heating the phone BECAUSE it has to load things from scratch rather than pull from RAM.
edit to add: even when something has outrun its usefullness (old program still in RAM, for example) then Android has a very good built-in cleanup system that unloads programs that have not been run for a while. This means that you don't even need to kill old programs that you no longer need!

Actually hte system uses the unused ram to cache other apps so they open faster when you need them..soeven though you clear the ram,it gets full after sometime.You need not worry about that because android can manage it well
And using some task killers could cause you battery drain and even leads to heat your phone
Try formating and reflash the rom

Let's go the crazy analogy route, 'cos they're always fun!
Say you're listening to music on some CDs. You have, say 5 CDs and on each CD there are a only couple of songs you want to listen to, so on a HiFi you'd have to keep switching CDs to get your play list. Let's say that they are also your favourite songs so you play them frequently. Let's call these top 5 songs "Messaging", "Gallery", "Camera", "Phone" and "Music".
So, you rip the CDs to MP3 and create a playlist. The songs are all strung together and they load and play significantly faster than switching discs repeatedly. This is what Android does with programs in RAM. To change between "Messaging" and "Phone" you just double click the file.
Now, you use a task killer to clean your RAM: What you have just done is delete all the MP3s from your computer, put the CDs back in their cases and put the cases back on the shelf. When you next go to play one of your frequently played songs you now have to go to the shelf, find the CD, put the CD in the drive, wait for it to load, then play the song.
Clearly the former is more efficient. The MP3s are not wasting power by being there, they're cached and pre-loaded so they load much more efficiently next time. Clearing everything away and reloading from scratch is much more processor intensive and that is what is generating that heat.

Thanks guys. Its not heating anymore. Thanks for all the help. You guys all get a thanks button clicked

You learn something new everyday. I actually didn't know about the specific way Android deals with ram. I've always cleared ram in the device settings in Airdroid (wifi file transfer app). Never get any battery drain/heatup issues though, but good to know about this, and will now refrain from being OC with clearing ram

Ram usage

Hey everyone.
I just got my 4x HD and i was wondering why i always have around 70% ram used on idle.
I checked in task manager and there was for around 200mb of services and apps running max, can't find where the other 400mb went.
Anyone knows if this is normal? How much ram does your phone use on average?

I agree with 700mb ram already used. But doesnt lag the phone though.

AW: Ram usage
its better when more ram is used. all the apps u used are stored in ram for quicker app start when run the app again. in other words: phone is faster when more ram is used. only if u hit the 1gb limit the phone would lag

thats true, but i too have ram problem in my o4x,
it starts lagging and freezing after some time if memory is not cleared by any task manager. and at extreme it restarts the phone.
i haven't installed that much apps yet, i installed more apps in my HTC Explorer and that phone never did things like this but this phone has double ram and still doing strange things.
and i installed swapper to solve the problem but now i'm stuck on boot logo, any help appreciated.
and any help on my bricked phone is also appreciated at my post here, http://forum.xda-developers.com/showthread.php?t=2192894

still, my phone uses 800Megs of RAM and constant lag.

fyi every time someone complains that their Android phone is using a lot of RAM an angel loses its wings.

but.. but.. but how will the games work smooth if there's only 100megs ram free?
I understand that system/UI works faster when everything is loaded in ram... but i don't like apps in background sucking my battery. I've seen this clearly in Battery Monitor. When ram is clear it uses about 25mW (on idle), with stuff in background it's closer to 100mW or more... I don't like my phone eating battery 4 times faster on idle that it should.

Again, this isn't Windows, it's Android. Free RAM is wasted RAM. If it has only 100Mb free and you launch a heavy game, it'll promptly free the needed RAM by offloading the least used stuff it still has on RAM.
On the other hand, if you call that program you only use once a day, it's probably still in your RAM, and will open as if you've only just used it (well, almost).
The used RAM isn't necessarily active, so not all the apps stored there are sucking battery. Your test results are accurate, but your conclusions are fallacious: yes, there's less battery usage when the RAM is clearest, but, as they say, "you've thrown out the baby with the bathwater", i.e. when unloading ALL apps, you also unloaded the ones that were consuming battery. On the other hand, you've also thrown out stuff that were just kept in memory, but weren't active.
The other problem with your approach is that, after you unload ALL apps, the most troublesome ones will probably reload themselves back into RAM. So, even if right after freeing RAM you reduce your battery usage, a few minutes later it will be back to the same.
What you should do is get a program like BetterBateryStats and find out what's actually sucking your battery. When it does, you have a few alternatives:
- uninstall apps that are sucking your battery but you just don't need;
- greenify some of the apps that you do need, just not all the time;
- freeze some apps (with Titanium Backup) that you don't use but can't uninstall.

i tend to disagree with people saying free ram is wasted ram and preloading apps in ram is good and that for this simple reason.
everytime you start a app that is not preloaded (it can only preload so many apps) it has to use cpu time to unload it then load the next app resulting in extra cpu usage = less battery time.
many people complain about battery life except me.
and i really manage my phones resources all day long and have nsane results noone else seems to get.
i have over 5 hours 30 min screen on time (me browsing watching youtube using whatsapp and so on.) and have over 630 mb ram free.
my total stanby time on lght use is 5 days with 2 hours 30 min screen on time.
i would send screenshots as proof but for some reason the lg 4x hd bluetooth wont install on windows 7 x64.
but really since i starte to actively manage my phone the battery lasts longer and i never had a stutter or anything.
and as a sidenote my phone is stil unrooted and stock v10h so with root i could prevent even mre from starting up and have even more free ram and better results.
and yes the poster above me is right some apps will reload themselves so IF you use a task killed prevent it from killing tasks that start themselves up again.
like google partner setup , media and more google stuff.

I have problems, too. My o4x is working about 2.5 years but im very angry because of the ram usage problem. The ram is always %70-80. And the phone is very very very... slow. If the cpu is works %80, what can i do ? The battery is finishing very early. I dont wanna new phone. Im not rich. I dont want to buy a new iPhone. Everyone say "The iPhone (ios) is the best. Android is the worst. Bla bla bla.. " And I believe this... PLEASE HELP ME (( :crying:

ART mode and RAM managment..?

I switched to ART mode mode this morning since I read that its faster and wanted to give it a go. However I have read about it but am not totally an expert. When I switched over it booted then rebooted to the ATT logo and hung. I had to use the 3-button combo to get back again after a huge heat up.
Anyway I now notice that in the RAM manager from the home screen I get for example 1.24gb/1.81 like normal and now where I would have had the same reading in Applications Manager In Settings I now get 0.98gb used - 870mb free in "Running". The way it reads seems to have changed and doesnt match the other.
Is any one else using ART and can share some experience on this at all.
Ive Also seen a post about someone mentioning bad signal on ART...?
Cheers.

I don't have root or anything to flash, why not test art?
I do notice a disparity as well, but mine is a little less prevolent-- my variation i think is as simple as fluctuation between redraw in between the two screens. I get 870/874used 0.96/0.95free-- I will say though, it seems to use a little less ram.
I live in a very strong signal area and that said, i don't see any signal difference. I do know some low areas so i can update once I've visited.
I did encounter the lockup at AT&T, that just required a reboot.

Yeah mate with no root for Roms I thought why not try it. I use a third party launcher called lucid and do notice a big improvement in scrolling between home screens and apps relaunching. I was a bit concerned about the different readings in the 2 ram managers and the freeze on boot but so far no issues. Just wondering how others are going and if they are using it since it wasn't in other Samsung devices too.

I use Nova Launcher, tried Aviate and Atom, I'll look at Lucid.
I also turned off all animation transitions in Dev mode. It's snappy enough to fly between screens instantly, also if you're not aware-- old pro move-- go into S-Voice(if you don't use it, but nobody does) and disable the double tap home function and then home key lag will be gone and the phone FLIES.

Cheers mate I'll give that a go. Lucid is a good launcher if you like vertical scrolling. I prefer that on these slightly bigger screens. Also icon resizing. Only set back is no folders. It's also got a side panel for short cuts just like in AOKP. You gotta like it or you will find it hard to get use to I guess.

Give the 0transition and no lag a go- it's like a new phone.
Have you ever tried Nova? It has vertical scrolling and icon resizing with folders. The side drawer though I don't really dig.
Have you any legacy apps onboard? I haven't installed older games yet, I'm sure some things will just crash fail.

You have to remember that even though ART is included on the S5s it is still considered experimental and has not been optimized yet.

Of course, nobody forgot this. It runs very well so far. I've tested it with all my daily driver applications and a few games that aren't updated for it and I've good results so far.

Yeah that's kinda what I thought since I haven't seen it in any other of my devices. Wouldn't mind seeing if anyone else is giving it a go. Was a bit worried after the freeze mate. Thought I was heading for a brick

Seems that ART is good on battery life. After 12 hours I still have 70% left where as I would usually have about 40-50%. Looks like using less RAM and opening apps faster is paying off.

It's an odd duck, my statistics seem to be garbage but the battery is doing quite well in visible usability. My battery usage stats have Android system @ 22% with Screen on time @ 20% w 4.5hrs(on) and the battery is just now at 46% I can easily hit 6.5-7hrs @ this rate, screen time and who knows what Android system will be at but i have no gdamn accuracy in the numbers other than the screen hours on that add up.
We shall see since I believe both of our Art switches were in the middle of a Dalvik discharge cycle, perhaps borked it all up until next full stats flush/100% charge.

I use Apex Launcher

My first run on ART and I get this. I don't know much about battery drain on this setting but it's consistent. On dalvik I had to charge every night.
1 day and 12 hours. So I'm getting slightly over 50% more.
That's also with the gear2 synced which should take more battery too.

First full charge on ART got 1 day 2 hours and 48 minutes, with 3 hours and 36 minutes on time. Had 37% left. Not bad at all.

ART has mostly eliminated the annoying unlock hangup that I was seeing. As for battery life I can't really tell a major difference; although coming from the i717 going a whole day is a miracle. Most days I end the workday after about 12 hours off charger with 40-50% battery.
If I forget to turn off the hotspot after using it I may see 30%, but that is after 8 hrs streaming data to my tablet and GPS on the old Note.

You won't see a MAJOR difference between Art and Dalvik. People would like to see it but it isn't there. A few sites have done more imperical things* that said mostly it's close to even with some gains. It's just better in performance of apps you use often, in short.

Just switched to ART today.....so far so good. All my daily driver apps are working great. Seems like switching to ART free'd up some RAM, im now using like 0.96 gb instead of 1.2 or so.

I definitely see some improvement in ram usage. I think this is what is also helping with her battery consumption. The only issue I do have is if I run the battery completely out or just need to reboot then it may stick on the boot logo and need the 3-button combo method to get our of it or even pulling the battery. Might happen 1 in every 4 times but worth it for the extra sharpness in performance. I'm happy with it so far.

Aftet switching to ART ive had lags all arund phone ,,, not much difference in baterry tho

I do have a lot of apps turned off and I am using a different launcher so maybe that helps. Not much extra installed either.

Phone using almost all RAM, lagging severely

I've only been really using my S6A for a few months, and in that time it has been getting exponentially slower, now to the point that it lags several seconds before showing the home screen. Upon checking the stats, I noticed that the RAM was almost topped out, and even a ram cleaner couldn't keep more that 200Mb free. I've heard this may be a problem with touchwiz, but I'm curious, is it really a common problem, and is there a fix? P.S. I only have two user apps running in the background, and they usually take up 50Mb of RAM between them, so it's not that.

My old Samsung galaxy express had an issue like this to the extent where I got annoyed and switched to the moto g3. If you use any app such as clean master, you may think it works, but it actually doesn't help, it makes performance worse.my suggestion is to uninstall any cleaner apps if you have any and restart your device.

Overheating

I bought my first Samsung phone in over 10 years, the Samsung S20 FE 4G with the Snapdragon chipset.
To my surprise the device is heating up very quickly while in use:
With light use, like messaging apps the CPU stays around 37 to 49°C,
While gaming it stays around 47 to 50°C+ (I believe the 60°C was the biggest temperature spike).
I've heard people saying that transferring data from your older phone via Smart Switch may cause this heating issue, but I don't think that should be a issue.
Lastly, I have no clue on how weather affects the phone's temperature.
Despite being winter, we're having temperatures around 40°C where I live, but even when the night comes and the temperature drops to around 20°C (right now it's 26°C and the CPU temperature is around 40°C, while I'm listening to music via Bluetooth and (re)writing this post) my phone still heats up (just not as much as in the rest of the day).
I think it's worth mentioning that the CPU temperature is also changing quickly, I don't know if that's normal or not but for instance, when I switch from one app to another, if the app I'm using to measure the device temperature (CPU Monitor) is to be believed, the temperature jumps some 2 to 5°C. It usually comes back down again, but I really don't know if that's normal.
I went to the Samsung store today, they checked, did some tests, and said that the temperature was at normal range, but they said that the temperature while switching between apps was a little strange.
They also said that their system detected a temperature spike caused by Fine Lock on the day that I bought the phone, which I find weird since it's only a launcher to the Good Lock apps, but nevertheless they advised me to uninstall it and keep monitoring the temperature for a few more days, and that if the device gets too hot (over 60°C), that I should go back again and ask for a replacement.
Anyway, should I give some time, should I worry about it, should I take it back to the store?

I have the same model as you and I haven't experienced any of the symptoms you are talking about. If I were you I'd return it and get another one. At least then you can be sure if it is normal or a defective device.

SmartSwitch isn't that smart especially between different OS's/devices.
I think you better start from the beginning...
Backup your contacts etc to the PC using cut/copy plus at least one other hdd.
Factory reset. Reload from scratch. Run factory loaded versions; do not update any at first.
Avoid enabling any power management at least at first.
See what you got and go from there.
It's likely not hardware at all but a bad configuration. Common with Samsungs and correctable.

Thank you. I'm thinking about doing it. I've talked to some S20 FE owners who live in my country (which is a very hot country) and they said that the device temperatures are basically the same as theirs, but at the same time I'm still worried about it's long term effects since I plan to keep this phone for at least two years.

Thank you, I did what you told me (except for flashing the factory stock ROM since I couldn't find it), I've only restored the apps using the Google backup, but didn't restore my settings. I've also did a mild debloat of the phone (removed Bixby and the Facebook apps) and while using the phone to browse through social media doesn't heat the phone as much as it used to, it still heats up more or less the same during gaming, so I'm guessing that might be normal.

Depending on how CPU cycle intensive the game is, it could normally use a fair amount of power.
Running background apps can make it noticeable worse though.
Try temporarily disabling Google play Services and see if that helps.

It's Honking Impact 3rd, it's not intensive like PUBG or something like that, but can be intensive depending on the game mode. It runs at 53°C max. I found out that one of the apps that I was using to measure the temperature apparently only shows the temperature of the hottest CPU core, that's why the temperature sometimes shoot up to 60°C whenever I took a screenshot for example, and then came back down to around 50°C.
But I'll try disabling Play Services and playing again.
Do you know if those temperatures are safe btw? Around 50°C while I'm gaming.
The battery's temperature doesn't go past 40°C, in fact I don't even think I've ever seen it getting to 40°C.
Anyway, thank you very much.

You're welcome. The Farenheit is scaled better for real world use.
140F is well within tolerance for the CPU/mobo as long as the battery doesn't get hotter than that. I don't let my battery go beyond 103F.
The CPU/mobo can handle up to probably 165F but it's best never to push it that hot as auto thermal shutdown doesn't always work in time to save the components that are running hot and have a sudden additional power usage spike.
Really the phone shouldn't feel hot... it's killing the battery too. Track them down.
If it feels warm when using the browser, something(s) are running in the background driving it up.
Any cloud apps, including Google backup Transport, Framework and Google Firebase.
Ditch any trashware apps like WhatsApp, Twitter, Instagram etc.
I'm using my 10+ in a case at a 75F ambient air temp browsing with a CPU temp of 89F right now. It is stock but heavily optimized.

The phone doesn't feel hot, unless I'm playing a game, depending on the game it gets somewhat hot.
It's been colder in my city these past two days, but tomorrow we'll have a temperature that's closer to normal. If the phone manages to stay in an acceptable temperature range I'll keep it, if not, I'll return it to the store and see what I can get done.
My old phone didn't have a plastic back, so feeling the phone warm is a new thing for me.
Most Google apps are disabled, I only use WhatsApp to talk to my family, I have Instagram installed but I don't even remember when it was the last time I've used it (I put it on deep sleep also).
Thank you very much once again.

Using power management can cause erratic behavior and sometimes increased power usage especially if set globally.

Using power management can cause erratic behavior and sometimes increased power usage especially if set globally.

With Power Management you mean the Background Usage Limits from the Device Care app?

Yeap. I have a 10+ running on Pie.
Your may get different results but it's a known source of instability and trouble.
This is how mine is configured.

I did it but now all my apps under Standby Apps are set as "Active" and I can't change it. Won't this consume more battery?

Once you do that you need to track down the trouble makers and deal with each on a case by case basis. Sometimes simply cleaning the system memory in Device Care can work wonders. Keep open apps to a minimum.
Here's the old version of Device Care. It uses 360° which cleans very well but is CCP junk.
To safely use it use Karma Firewall* to block its internet access. It will still run normally.
Before uninstalling your current version use Apk Export** to make a installable copy, just in case.
*freeware, uses almost no battery
**freeware that is very useful to backup all your apps and updates for future use... ditch Playstore for reloads

Thanks. But I can't uninstall the current Device Care app. Is it safe to do it via adb?

This is normal. Just because their bucket state is marked as active doesn't mean they are running. It simple means Android is no longer managing them by assigning a bucket state to them and so on. Google it... it sounds like a great idea but it never worked well for me in practice. Android still manages the apps with it off less the added resource burden of this system.

Sorry. You are correct.
I got rid of the updated version by doing a factory reset. You can try loading the older version by first force stopping the loaded version. It may worked... try this first.
I guess a adb edit would allow you to disable the current one. If the older one will load is another question.

I'll see what I can do.
I'll also test the phone again tomorrow when the weather in my city will return to normal. If everything goes well I'll keep the phone, if not I'll have to take it to the store and see what they offer me, a replacement, another device, I really don't know how it works in this particular store that I bought.
Anyway, thank you very much, you've been very helpful!

My 10+ was a battery guzzling hot running hog before I optimized it. It took some time and effort
Today you never guess it is that same phone.
If there's any doubts get a refund. It could be hardware, even a heat sink or pipe issue.
That said this is a commonly seen problem that has nothing to do with hardware in Samsungs.
Do some Google searches for that device and hot running issues. See what you find.

I can relate. I had a Xiaomi before this one, and the stock ROM was plagued with app killing and battery drain. I'm glad you managed to work it out, all I had to do was switch to a custom ROM.
I've tested the same game again today since the temperature has gone back to normal where I live, and while the CPU temperatures are in acceptable range, the battery temperature got to 40°C/104°F.
I did some research regarding overheating on this phone and it's always the same thing, some have it like I do, while others say the phone doesn't even warm up the palm of their hands. So I don't know if its a configuration issue or if there are a lot of defective devices out there.
