Galaxy note over heating (System UI hogging CPU)

Hi,
I've a G-Note running ICS-4.0.3 , i recently noticed my phone is getting really hot and resetting automatically at times, on closer investigation i see 'CPU spy' data showing my phone running constantly at 1400Mhz mode!!! wanting to find which process is doing this, i downloaded watchdog lite and noticed that 'System UI' process is running at 49% approx CONSTANTLY, killing it re-spwans the process!! any idea whats causing this?? Please Help!!
Not rooted, never flashed, on original upgrade, have nova launcher, use it rarely. no other launchers installed.
Restart fixes this sometimes, sometimes not.
Thanks in advance,
Ramgo.

Not that i can think of as a problem, been happening for a while now, could be any of the app! i have like 200 installed!!
Now its not system UI, its android syste, badass battery monitor shows kenel to have taken most of the battery (which seems mostly loop task, is this bad) and then android core process.

well try to remember from which app on this issue showed up.I had battery drain problem turned out it was because of an app that I had installed.So I unistalled it and my problem went away.Yours should be easy to spot try unistalling the recent apps or the ones you're suspicious of and see when you get deepsleep.

Check your battery status and see for the battery eater apps

its android system process now, badass battery monitor shows kenel to have taken most of the battery (which seems mostly loop task, is this bad) and then android core process. Not something i can uninstall, i have done a lot of analysis before reaching out for help!

I infact got deep sleep the whole day, 15 hrs just 10 percent drained! this problem has been occuring intermittently, deep sleep is still happenning, but when the phone is screen ON, its in the highest mode.

Hmm things got complicated.Like I said if everything used to be normal then all of a sudden this problem began then it should be an app I suppose?!Just like my case.
Install OS Monitor and see what's hogging your cpu maybe you can pinpoint the application if that's the case.

did anybody have a problem with Gsam battery monitor after it was upgraded from Badass battery monitor??? i was looking at it and was showing 100% battery drain due to application ( 0% for screen and phone radio)!! i have uninstalled it and seems fine i guess! atleast for now! charging now and its in the expected 200Mhz state.

Yes will do that!! Thanks! read my comment below, i think GSam Battery monitor submits some task or makes some query to the kernel which makes it to go in a loop, hence the android system seems to be using more CPU and not battery monitor itself

The problem is back!! HELP!!
I checked OS monitor, nothing seem to be hogging, occasionally android system, overhearting near the camera and resetting automatically, please HELP!!!

Hello,
I'm having a similar problem. When my Note is in standby sometimes it overheats without any apparent reason and battery drains very fast.
I haven't been able to trace the origin of this problem. I'm running on ICS 4.0.3 stock and no ROOT.

Have you installed any kind of launcher on your phone? If you have, do try to uninstall it for now. Install BetterBatteryStats, turn off any data connection.. 3G, Wifi, Bluetooth.. Remove any Live wallpapers(just use a static one), Uninstall any apps that connect or syncs online.
The last thing I could advice you is turn off Airplane Mode (at night), charge up your phone to 100% and just leave it for a day. Check back on BetterBatteryStats after on what apps/wakelocks is triggering the overheating.

Lot's of work... I'll have to find some time to try all of that.
Thanks.

Early last week my Note started to reboot whitout any apparent reason. It happened 2 to 3 times a day. Specially in the morning when battery was still above 60%.
The overheating also happened from time to time but not everyday.
Saturday I figured I had to do something extreme to end this.
First I downgraded to a pre-rooted GB rom. Afterwards wiped the GB rom. Then upgraded to stock ICS. Everything worked out fine and was very easy to perform, thanks to all the guides available on XDA.
Last of all I rooted the ICS.
Until now the Note hasn't overheated or rebooted again.
I really thought it would be harder to do all this. But now I think it would take me about 20 min to do all these procedures.
Thanks to all the people that posted the guides on XDA.

I'll take that as a joke.
Three days in and still no unwanted reboots or overheating.

Gents if you have nothing constructive to provide in assisting the users with real help, please refrain from off topic mindless humor. Thank you.

A week after I've re-flashed ICS on my Note, the unwanted reboots have come back.
It must be some app I've installed again or maybe something much worse. I've read lots of threads and was wondering if a custom kernel and a different ROM might solve this problem.
One thing I've noted, the reboots never happen at night only during the day (mid-morning and mid-afternoon).
Any new ideas to help me find the source of this problem?
EDIT:
I'm running on LPY Kernel, so wipe is not an option...

[Q] Android OS killing battery. Any solutions?

I don't know what's causing this. Anybody have the same situation as I have? Any ideas to remove Android OS battery drain? TIA

Remove Android OS from your system :thumbup::screwy::silly:
Seriously its core process of entire OS (operating system).
Without it your phone can't work

Every now and then i have the same problem, Android OS chewing my battery dry...it keeps my phone "Awake" all the time,like when i sleep for 8 hours it eats my battery over 30% ... but,after a restart or 2 or 3 restarts it gets back to its usual behavior,phone goes to sleep when i don't use it and i get easily 2 days of medium usage...
i still have stock ROM and dont know what keeps the Android OS working all the time in the background, but as i said it happens rarely,maybe 2-3 times a month,so probably its some sort of a glitch
P.S. @NoTricks , 2 months ago i installed Dropbox app and even i have had its settings not to upload anything automatically, the application was working all the time in the background killing my battery super fast...after i uninstalled it the phone went back to normal battery usage...just my personal experience with that app....

Yeah, Same Here, My battery drains faster when I install an app that always runs in background. I tweaked my S3 Mini's Minfree values and it helped a bit, but it reduced my phones powers in multitasking.

Problems after Repair (Battery or Processor)

I sent my phone in for the purple camera problems and I got it back last week.
When I received it, it was updated to 4.3 Sense 5, most likely from the latest RUU.
Since I got my phone back, my battery has been horrendous and I noticed it had heat problems. I checked battery health and it said it's good, so I figured I just needed to re-calibrate my battery so I gave it a week of use. It's been the same horrible battery life.
I checked for wakelocks but there were no significant ones I haven't seen before. I've attached some screenshots of battery use. One thing that confuses me is that it shows Wifi running for 9 hours, even though I had it off for most of that. Is this normal?
To deal with the heat, I had to install a custom kernel and undervolt/underclock a bit. Before flashing, I noticed this thing is forcing itself to max frequency (1.7 GHz) which explains the heat. So the battery is draining because of this, presumably. I switched to intellidemand and lowered the clock a bit so it can last 12 hours (Doing nothing at all) instead, but that's still horrible compared to what I had before I sent it in.
Before I sent my phone in I typically had stock kernel while using insert coin or trick, Power Saver On, Auto-Sync Off, All Play Services/Google Now On and got 4-5 hours OST. Now I can barely get 2 hours.
Does anyone know where I can look to find the cause of my processor forcing itself to max frequency? I want to figure this out before I annoyingly have to send it in again. (Have to S-On/Re-Lock again =\)I was thinking maybe something shorted when they replaced the camera.

Thanks, I guess it's normal then since I never turned that off before.
Now to figure out why the cpu is forcing max frequency all the time on stock kernel/firmware.

must be some rogue app, maybe best to factory reset, install (or restore) apps one by one.
if you're rooted use Titanium Backup, and check out Greenify for facebook and similar apps.

Those screenshots were from after factory resetting. I'm considering RUUing back to 4.1.2 and flash my way back to 4.3 and see if that helps.

That gained me maybe an hour. Just applied a Sense 5.0 4.3 and it seems to be better. 10 hours on idle with 40% left. A lot better than 8 hours to dead. I'll give it a couple days and re-calibrate the battery to see if it's all okay. I've noticed very steep drops from when the screen is on. Thanks again for the help.

[Q] Battery Bleed

Hi.
My battery loses abot 2-3% per hour in idle. Is it some software or hardware problem? Or Tegra 4 specific issue? (No Wi-Fi, apps closed etc)

Yeah seems to be a common android problem, some apps have runaway processes, others prevent deep sleep and I have also seen kernels lock CPUs. Shame Google can't put some effort into fixing it.

It's not an Android or a Google problem, it's the fault of the developer of the App which is causing this...
Since 4.3 I lose 0 % over night and I can use the table 1 hour every day for reading magazines, e-mail and angry birds for at least 5 days! Just great

Google / Android should not let an app prevent deep sleep imo. Or runaway with resources. But yes you are right some responsibility has to be with the app developer for sloppy programming as well.

In some cases it could be useful or even wanted. Think of an emergency app with running bluetooth and GPS. You would not want Android to kill the app in the middle of your tour

Cold boot didn't help and no draining app seems to be running(. Is a hardware issue possible? Is there a way to check it?
Here's a screeshot from System Panel (results of this night's battery bleed)
P.S. The back of the device seems a bit warm when I touch it...

You can wathc under "settings" -> "energy management" -> "energy table" which app it is and you can prevent it to wake the device up and to keep the device alive.
A few weeks ago I had a similar but stronger akku draining problem with the google apps but its gone (a pitty that I can´t say what it was: me doing this things in the energy management or google updating its app).
My google play-services still wake the device 869 times in 3 days.

New results. Very strange. No power consuming app seems to be running, but I still got -3%/hour.

Battery statistics shows that 80% most power is consumed by the screen. But it the tablet was in sleep all the time, so the screen was off...

Check in Settings on "Energieverbrauchstabelle" (something like "engery consumption table") from Asus, there you can see the power consumption of the apps without Display. If you click on a specific app you can disable it to keep awake or wake tablet from deep sleep...
If that not helps you you should reset everything and go back to stock. Then you can check without installed additional apps if your "bleeding" still is there. Then install one app after another and wait between every single one to check which is the "bad app"...

So, in fact it was a hardware issue. I took another unit and it works perfectly. For now...
Anyway, thanks for your help, guys

With tablet off (deep sleep) I get 1 % battery loss in 12 hrs.
Best I have ever seen on an android device.

Yep, now I've got the same thing. 1% instead of 30%

With my N4 and now N5, I use better battery stats to find the culprit of battery drain. But you have to be rooted

have you registered a asus account on the tablet?
i did and i got same issue was chewing through the battery like crazy.
go to settings and power consumption and it should say how many times it woke up the tablet or stopped it from sleeping

I might send my phone back it doesn't seem right that

In my case main metrics (e.g. SOT) are refreshing when I'm entering the view. I'll try to record screen later.
On the other hand when I was testing battery usage of Tidal, the metric related to this app has been refreshed after some time. For example, I was using the app for 30 minutes (I've used timer) and right after this time I've entered battery stats and I saw that app was in use for ~20 minutes. After some time I've reentered battery stats and values has been updated.
BTW, I don't know if it's only me, but I have feeling that Tidal / Spotify are draining more battery on S21U in comparison with e.g. OnePlus 6. It's Exynos related or I'm just overreacting?

Last time I had a major update on my SD888 S21U, it said right on the screen that it would take a few days for the battery tracking to re-enable itself as the phone had to get adjusted to the software changes.
You're probably experiencing the same thing and just didn't get that message on the screen in the battery menu.

Potentially although it's just as easy to get a new phone this one seems a bit stuttery
