SM-N910C heating problem after 5.1.1 update - Galaxy Note 4 Q&A, Help & Troubleshooting

I want to share my experience which is causing me trouble now.
I have a Note 4 SM-N910C which had an issue after updating to 5.1.1 lollipop. For about 2 days after updating, a strange thing happened to my phone. The whole phone gets hot. The screen, the sides, the back, you can feel that it is hot. At first, i thought of turning it off to cool down the device. To my surprise, the device is still hot even if it was turned off. So I removed the battery. Turned it back after 30 mins or so and restarted the device. But this time it won't turn on. I charged it and the battery was still at 25%. Then it turned on, the device slowly heats up. I then fully charged it and see if what is going wrong. But i cant think of anything i did for this to happen except disabling some apps in the application manager since there is still no root for 5.1.1 that time. Still the problem persisted for a day and my device dont last for more than 3 hours from full charge until it drains.
Then i decided to downgrade to 5.0.1 lollipop. But still the problem remained. I decided to show it to a technician, told about the problem and he said, there a lot of note 4's brought to them with the same problem. He said it is a common problem of note 4. What causes the issue he said was that the Power IC id damaged. And it is hard to repair. The solution is either to change the board of the device or change to a new one if under warranty. Since I tripped my knox, there will be no other way except to change the board which cost 75% of the price of the device or I will dispose the device.
If there are other solutions, i would be thankful for it will help me keep my device. I dont have the money to secure a new one.
What could have caused this problem? Thanks for any solution i could try..

[Q] Nexus 4 Instant Battery Drain/Shut-Off

Hi
I have recently started having a problem with what I presume to be the battery of my Nexus 4. It seems to have started suddenly about a week ago, though was working absolutely fine before. I don't think it was due to any specific app having been installed. I have also done a factory reset on it, but that didn't solve the problem.
Basically, the battery will discharge to about 75%. The phone will then suddenly switch off; turning the phone back on, it simply shows the battery to be fully depleted and switches off. If I plug it into a power source, the phone turns back on and begins charging, from 0%, though seems to suddenly fully charge it within about half an hour.
My phone has not been rooted.
I would really appreciate any help/advice on this issue as it is incredibly frustrating having to have my phone almost permanently on charge.
I have attached two screenshots of the battery usage graph.
Thanks!

If you are on stock, try flashing the stock image(4.2 or 4.3 up to you) there's plenty of threads on here thatll guide you thro the process.
I've had the same issue about three times, during the first week of using my Nexus 4 (about half a year ago). I've already had my mind made up to RMA it, but waited for it's shut-off to happen once more to collect some evidence of this problem and... it never happened again. I'm pretty confident that I didn't install anything that might have helped (I only installed BetterBatteryStats to check the instant drain, but really doubt it could change anything, it's just statistics), and I've never factory wiped the phone's data yet.
I've been searching for answers around the internet back in May, but never found anything of value, so my only advice is... wait a little, and if it doesn't get better itself return it to the merchant. My previous HTC phone was restarting almost everyday from the first day I bought it, until a month later I returned it for warranty repairs and after they changed almost all internals of the phone it never crashed again (till today, since I still use it as GPS and media player when running).

Battery draining even while the note is turned off or in airplane mode.

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.

Crashing, turn off and massive battery loss

So a few times now my note 4 has crashed (black screen) and turned off. When I turn back on the battery level has massively dropped (30-40% gone) yesterday went from about 40% to 0%. The 40% seemed accurate as using it not too much and usually about that percent at that time of day. Also noticed a few other things, when I connect my note to the pc it takes a while to start and stop charging and isn't being recognised by the pc (or the note isn't detecting it is connected to a pc - only charges)
Any ideas?
Try a different battery?
Are you rooted or custom rom?
Hi, not rooted and stock rom. Had an update yesterday which mentions better battery performance. maybe they fixed something. I'll give it a week. Have also contacted samsung. Not sure if battery is included in the 24 month warranty
I'm running stock 6.01 deodexed and rooted, It's happened to me a couple of time. Either its a samsung bug or the battery is just recalibrating itself. Probably the recalibration
That's good to know but worrying. Its really bad if it happens when I'm out. I think I have a good 10 hours of battery and then bam nothing. If I get anywhere with Samsung I'll post back

Random turn off

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.

[Q] Battery problem - suddenly turn off

It’s been a while that I have a strange problem with my batteries. I used two different batteries, both original, charged with the original charger support for the second battery (sell in bundle with it).
It’s almost two months that my phone started to turn off suddenly when the battery level is around the 30%, with both of them. I thought it was a problem related to the batteries age, since I’m using them in the last 2 years.
I tried anyway to contain the problem. As first option, I did a battery calibration. To do this I needed to discharge all the juice from batteries. I noticed that the residual 30% that I saw before the phone turn off wasn’t a fake value: it was real.
When I turn on the phone in recovery, the battery level is exactly the same that I have when phone turn off itself. Moreover, to reach 0% of battery level I have to wait a while and I can keep the screen on (always in recovery) for about an hour. On the other hand, if I try to restart the system, the phone turns off just after the Samsung logo of starts a non-sense bootloop.
Considering what I ‘ve written above, I think that my problem it’s not an hardware problem.
Does anyone have similar problems? Do you have any suggestion to avoid it?
As supplementary information, I’m running the last Italian official firmware with TWRP and root.
same problem
I am note 4 owner for 1 week now
it is an used phone (rebuy)
original rom 6.0.1 newest updates
on delivery the batterie was on 0%
first time use it shutdown at 35%
without warning
now after multiple charging and calibration
it shutdown at 20%
in 2 days I will get new Batterie and I will check again.
maybe batterie is old
Similar issue in the last week or so with my N4. Original replacement battery, 10 month old, turning off with no warning on reaching between 20-15 % charge mostly if i try to use the camera. I've put back the original battery and seems fine for now. Ordered another battery, Anker this time, just in case
Yeah Samsung carefully crafted these batteries so that they won't work any more after six months of usage of something. Mine is nine months old, the phone itself, brand new, and mine turns off at various battery percentages, sometimes its 5, sometimes its 12, I have stopped caring and I charge whenever I get a chance.
Conclusion Faulty Battery Only
Any battery poerventage is mainly determined with help of its volatage. As battery discharges this voltage also reduces. As battery grow older, we is gradually unable to handle the load as it used to when new one. Also battery life is determined by its charging and discharging cycles. It was all about basic. Now talking about note 4, being andriod fone and requres lot of battery so we usually charge it for 2 times depending on use.
The same problem was faced by me as well for note 4 at 30% it used to reboot all of sudden and thereafter bool loop (in actuality it is not as battery deoesnt handle load and it again starts to boot so no home screen). Replaced the battery with original one a month ago and now issue till date and fone lasts below 5 to 10% with 4G on and doing browsing.
So it is concluded for sure that battery problem.
Weird thing last night i experienced the same issue! And my phone is only 8 month old, i think this issue it's related to Samsung updates.. my phone did shut down in exactly 30% and started to go in bootloop i removed the battery and put it back and still the same i was about to factory reset my device for god sake ? luckily i did connect my charger before i factory reset my phone i gave it one last try and it did boot normally.
So i am not really sure what is going on.. no more updates for me unless it's a major changes

Happened to me too. I think it's the battery, I tried several batteries, some cause sudden power off some doesn't.
I'm upping my thread after two months to say that I solved my battery problem changing them. I bought a new one from Samsung official store and now I'm able to do more than 4 hours of SOT and charge phone once in two days (Red Dragon Note 7 porting). Before to change, I was not able to use any Sammy ROMs, due to several reboots and disgraceful battery life.
I don't know if the battery is the guilty for everyone's problems, but I really suggest to try to change it. Just, be sure to buy an original one, because there are a lot of genuine clones, especially on e-commerce sites.
For what regards the problem itself, I think that the cause could be the use of a different charger (Samsung, but for an earphone), coupled with the extra battery kit. Unfortunately the original adaptive fast charger stopped to work a month after the phone arrived and I didn't bother about it.
So, I also suggest to use only the original cables to charge the device.
I hope that this testimony will help someone with the same problem and, at same time, I also hope that Samsung will consider to use again removable batteries to give people the opportunity to do what I did.
