Hello,
I had an exynoss note 4 for over 3 years now and was always happy with it.
Recently I started to feel the phone getting hot and battery is not lasting as long as before (this battery was bought last year).
I checked with CPU Z and the exynoss was reaching 57 degrees just by scrolling in different screens like home and chrome.
What do you think the issue might be ?
Boot your device into Safe Mode and see if that still happens. If it doesn't then a rogue app is using all the resources on your device.
Try wiping the cache partition in Recovery Mode and performing a hard factory reset.
Mine was messing me about earlier this year, did a factory reset and clean setup - back to like-new! You may also need a new battery, but I'd try the factory reset first if the battery is a good one and only a year old.
could be emmc fault this is how it normally starts. battery drain and the issue you have.
Here is a video showing how to fix emmc fault.

I got my SGS II since yesterday, but I already have a problem.
When using the device, there is always a chance that the screen suddenly freezes. No matter what you are doing at that moment: browsing, playing a game, listening to music,... . And the processor usage has, in my opinion, nothing to do with the chance of freezing.
The only thing I can do is resetting the phone by using the power button.
After the phone rebooted, I noticed that the battery level dropped a certain percentage. The amount depends on how long you wait to reboot the device.
Now, last night, I left the phone behind with a battery of 20%. The strange thing is that when I looked this morning, the battery was 25%. And on the graph you see that the battery level increased. The time span was circa 8 hours. (The device didn't freeze in those 8 hours, so it only freezes when you actually use it)
Somebody recognizes this problem? Has it something to do with the battery or the device itself?
which country ?
Did you try updating the firmware of your phone?
@ Rouvax: Belgium! Why?
@ otacon888: Yes, I did. Still the same problem.
Brand new i would take it back .
jje
Yeah take it back - you don't want to pay this much for a glitchy phone.
(edit) Actually do a factory reset first and if that doesn't work, take it back.
I have this deadly battery combination that I can't shake off :
com.android.systemui + Samsung Sview cover + pin lock screen = huge battery drain
I have a Note 3 N9005, 4.4.2, stock, with the original Samsung Sview cover and the screen is locked with a pin. From time to time, say once every 2-3 days the com.android.systemui is draining my battery, taking hours of CPU time and resulting in heat and battery drain. The phone is new, had 4.4.2 when I bought it, so I don't know if I should perform a total wipe/reset.
I've read some threads that other people with other Samsung phone models (S4, S5) have the same problem as mine, in fact the combination proves to be a problem.
Is there a stock firmware that I can flash to get rid of the problem?
As more info for the screenshot, the talk time was 40 min and the screen time was 2 hours
Also I am under the impression that the drain takes place faster when I am using the phone (screen on). Yeah, I know that it is normal that using the phone would drain battery faster but this is WAY faster... like droping 1% every 2-4 minutes or so

Try the 3 consecutive Wipe Cache method. Some reported it fixes this.

Thank you for the hint.
Went into recovery and performed 3 wipes, one after the other...
Just o be clear, I did not perform a restart after each wipe.
I will come back with the results... it might take a while because usually after a restart it used to work ok...
I am hoping for the best,
Thank you !
I am sorry but it did not work... for the first 2-3 hours since the cache reset the com.android.systemui showed a decent, low 2% battery usage but in the last 20 minutes (after 7 hours of use) raised up to 18%, the phone is lagging a bit and the com.android.systemui shows :
CPU total 18m 46s
CPU foreground 19 seconds
Stay awake 27 seconds
The funny thing is the CPU total does not stop... as i am typing the com.android.systemui raised up to 22% and battery dropped by 2% and all i am doing is looking at the battery menu section
I am open to suggestions and ideas... maybe a link to the latest stock stable european firmware... anything
This com.android.systemui acts like a virus, slowing down the phone, eating the resources and battery.
The build number for the os is KOT49H.N9005XXUENC2... if it can help anyone.
Thank you
L.E : the com.android.systemui shows 28% battery usage now and the battery dropped by 6% in 8-10 minutes, i am so happy
from recovery make factory reset and wipe cache then flash a new stock rom from sammobile.com
Cocoooo thank you for your input but I am trying to avoid that ...if possible.
I flashed the phone with Samsung stock N9005XXUFNG2 rom... I'll let you know how is goes...
If this is not working i will backup, wipe, clean and reflash it with the same N9005XXUFNG2.
So far it is working... hope I can dodge the full backup/wipe/reflash thing
It's still working... although I see Cell Standby eating more battery then my previous firmware.... anyway... so far so good
Hi ..
I faced a terrible lag with my SM-900 after 4.4.2 update and I read a lot about this bad combination (S View + Lock with PIN) but I was forced to use the lock screen bcz of the company email server.
So, I decided to go into some experiments:
- Wiped cache partition: didn't solve
- Flashed stock Rom: didn't solve
- Used stock back cover: didn't solve
- Removed the exchange account and lock screen: didn't solve
So, I decide to start from scratch. I flashed the stock rom with Odin then a factory reset without the S View cover. I didn't install except very few apps (FB, Whatsapp and viber). The lag disappeared and the system was snappy and very smooth. After couple of days I put the S View cover and the system kept running smooth as is. After another couple of days I enabled the lock screen with PIN and the system is still in a very good shape and the clock of the lock screen always shows the right time and the home button response to wake up is perfect.
That eliminates the theory of SV+LS cause of lag. However, I 'll wait for few days then I will configure the company exchange account and update this post again.
Is there anybody else with this problem.It started monday i turned my phone on but it didn't start.The battery was 0% while i shutted it down with 78% of juice left.I charged the battery but it drains down real fast!Even with the screen off at night and no wifi or edge/3g/4g i still lose about 10% every hour!
I've used the note for two weeks without any problem.Rooted with Xposed Greenify and most of the bloatware disabled.Same setup as my Notepro 12.2 and galaxy mega(no problems with those devices).Battery life was pretty good about 5 a 6 hours of screen on time.
Tried better battery stats but no particular wakelocks or anything??I've ordered a new battery and that will arrive tomorrow.I can do a test then if it is the battery or the phone which is causing this problem.
It's a note 4 910c.
I have similar problem with my 910C...Everything was ok for first two weeks and problems started when I enabled LTE at my mobile operator. No matter what I do, I have huge battery drain like you said. I've also tried with disabling 4G/wifi/data/sync/airplane mode/removing apps... I even tried factory resetting 2-3 times and flashing stock rom via odin...Nothing helps...
I'm looking around on various note4 forums but I'm getting out of ideas...
I had an initial battery drain issue which ive managed to resolve. Took a few factory resets but for me it looked like the galaxy apps ap. Once you open it a single time it updates a few things and thats when i started to see wakelocks. Ive reset and avoided the galaxy apps completely and now wakelocks have gone. Might be a placebo but seems to work for me.
I have 2g,3g and lte enabled.
Oke i enabled 4g from the first time i used it so i don't think that is the problem.I was thinking about a factory reset but i'll wait with that untill i tested the new battery.
Will give a update tomorrow!
I had the same problem after one week of normal use. It was a hardware issue and the service center changed the phone board under warranty.
Well tried a brand new battery but still the same!Lose at least 10% every hour and i am not even touching the phone!!Sending it back for another one.
It's happened to me once but touch wood only once where I lost 70% overnight in airplane mode
Could be the media scanner? I was having media server and scanner drains until I installed a custom rom and disabled it.
I'm experiencing some occasional (every day) boot loops that almost always require a hard reset to get out of. Usually, after a hard reset, my phone will work fine for some period of time. Probably related, I'm experiencing much faster than normal battery drain. I'm used to a full day's worth of battery with this phone, but am experiencing barely enough to last my through a work shift (7am to 4pm). Also, weird spikes of battery loss after a boot loop + hard reset.
I am not sure what is causing this issue. Sometimes, setting my phone down on a table will begin the boot loops, leading me to believe that the battery could be loose or faulty.
As you can see, there is a gap when the phone is boot looping and then a huge loss of battery life. My phone is a T-Mobile USA model that is CF-rooted. I don't know a lot about root, but I'll answer any questions that may come up.
What could be causing this? Any ideas on how to fix it?
Update: My phone battery drains every faster now and cannot even boot to homescreen at all. I am having major problems and cannot use my phone for any function.
Any help at all would be appreciated. I don't want to just take a loss on this device.
I don't know for how long you've been using the phone, but maybe the main problem is from the battery, have you tried using another battery?
and do you get the boot loop problem when your phone is connected to the charger?
Hi,
I have a Note 4 SM-N910C variant that is almost 3 years old.
Starting from 5 months ago the battery level would start dropping fast from 35% to 0% in like 2-3min after which the phone would turn off. If i took out the battery and insert it again, start the phone again it would show around 30% battery level. After a while it would start doing the same fast drops in battery level and so on.
I got a new battery, not OEM and now it doesnst do what i was facing above but it randomly turns off no matter if im doing something with heavy or no load on the device.
The turning off usually happens after the device goes bellow 50% battery level.
How can i test if all the components are ok other than the battery which seems to be faulty in my opinion.
I did order a new original OEM battery but it will take time to get to me.
I want to find out if the rest of the components are functioning without faults so i can decide whether i should get a new phone or not.
Please assist.
New battery
I know its not the same behavior, I have 2 note's. Mine is only a couple of months old while the one from my wife is build in 05/15. Her phone when we just received it would refuse to charge above 96%. Sure the phone would say 100% but as soon as you unplugged the charger it would drop straight to 96%. It did this on 3 different batteries, exactly the same behavior. All these batteries are OEM. When you plug it in it would go rapidly to 100%..
Anyway, I wiped the cache on that phone and since this it charges normally.
Been comparing the battery drain and both phones are using around 6 to 8% per night while on stby with wifi on.
Just try this, it may help you!
Thanks for the replies.
I did try wiping the cache and even did a factory reset.
I rooted the phone 2 days ago to try and recalibrate the battery but i didn't help.
I think the situation isn't degrading cause from today the phone is constantly hot and the cpu is running at around 48 celsius with 7-8% load.
I'll see what happens when the new battery arrives, maybe the phone is heating up cause of this maybe not. It's even eating the battery from 100% to 0 in 2h with no real load on the phone.
Do you guys think a benchmark program will force it to thermal shutdown if this is the issue.
I'm still trying to find out if only the battery is faulty or i have a dying phone.
To me you have 2 problems...a faulty battery and a (new) software problem on your phone.
Constant being warm with a cpu load tells me something on your phone is running all the time consuming your battery and causing your phone to heat up, unless it behaved the same before the factory reset and rooting?
You are rooted so try Wakelock detector for root to see which app (if any) is causing your phone to behave like this.
I will try wakelock to do its thing during the time i sleep. But if that doesnt help ill try a custom rom. Im not gonna factory restore and go back to stock rom. Gonna move away from that and see what happens.
