Hello everyone!
I have recently purchased a galaxy note, and since then have had a constant problem of auto shutdown, at the beginning it happened once or twice so I didn't even mind, but now its just becoming too frequent for the phone to even be usable!
I can't return the note, and have no warranty (nor money to buy another one). Son no viable solution there.
I sold my previous phone so I could buy the Note, without it I am phoneless.
I have looked EVERYWHERE for a solution and haven't come to one single conclusion yet!
I will now post some facts about the phone's situation:
Model GT N7000
Rooted: yes, via cwm
Rom: Jelly Bean 4.1.2 Beta, flashed via cwm (but the issue occurred on stock ICS, gingerbread and costom ROMs too, stock ROMs where flashed via PC ODIN and mobile ODIN)
Kernel: Phillz flashed via cwm
-Does not shut down while connected to charger (and is charging).
-Tried different kernels and ROMs, official and custom ones, and the bug kept happening.
-Shutdowns are completely random (although I found that using ROM Toolbox and setting CPU min to 500 and governor to Performance the phone became more stable and didn't shutdown so frequently. Recently these last 3 days this has become pointless, the phone is unusable unless connected to charger)
-Auto shutdowns happen when phone is in sleep, or awake, no matter what I am doing with it, it just happens.
I am thinking of replacing the battery, since no matter what software changes I do it keeps shutting down maybe a new battery will help.
But then again, I don't know, I'm just desperate...
Thank you for all those who take the time to read this!
Interesting, maybe the logs show something. Check logcat app for that. Elixer2 has a good overviewable one. There might be some hints shown as to what is happening. I cant really help you with interpreting.
Do you do clean installs? mind the brickbug
Battery levels, they show correct values? Also after reboot same value as before? You can set in settings, display I think battery tp percent. Easier monitoring from statusbar.
Try andrometer to check voltage levels as wel. Fully charged should be around 4200 mv.
Do a little dance to brighten up your mood.
Next, or first, check if battery contacts are clean and alligned when putting battery in. It might just be a loose fitting. I doubt that thought.
With autoshutdown, you seen android saying, shutting down now, or does it go black and just crashes so to speak?

Thank you so much for the help!
I have been suggested to purchase another battery, and had actually been thinking about that!
Will andrometer confirm my suspicions that it is a battery issue?
The battery connectors are clean, cleaned them when this problem first appeared.
And the shutdown is as if I suddenly removed the battery, the power is cut right off the device.
I cant dance but I'll play guitar, that always helps me, thank you for the suggestion! xD
hum, not software related imo, really an hardware issue, electrical issue, related to battery as it does not occur while charged.
first of all: easily done: remove any SD card and try. still the Pb?
then borrow another battery, fully charged, and try. Still the PB?
then with your own battery again (as it does not come from the battery), check the electrical contacts (dirty, embossed...), try to check that mechanically the battery is firmly kept in place, add sticky tape/pieces of paper to maintain the battery. Still the PB?
then i am afraid that the best to do is going to... after sale service... it may be only a small welding a bit cracked on the power circuit, sometimes a small vibration or a temperature difference opens the power line and your phone immediately shut down. It is almost impossible to locate and to fix for common people.
good luck mate !
Side note: setting CPU min to 500 and then setting governor to Performance is pointless, because performance = always max CPU frequency.
Anyway, I can think of various ways of checking whether your CPU is misbehaving at some frequencies (like SetCPU stress tests on different freqs set to both min and max) but that's likely not the case, all signs do point to some kind of battery issue.
If I were you, I'd try to find a battery somewhere (friend/relative/whoever else with GNote, or even a shop) and see if the problem persists with another battery. If it disappears = buy a new battery, whether official or copy or bigger size, whatever. If it persists = at least try to flash some more customizable rom/kernel combination, of ICS kind - where you can over/under-clock/volt.
Thank you saturax555 and GwynBleidd for your suggestions!
Unfortunatlly I dont know anyone close to me that has got a Gnote, but I will buy the battery and test it out, its not expensive at all, I've seen a 2600 (Or 2400, can't quite remember) mha battery for salle somewhere, if it fixes the issue I'll even end up with a larger battery!
I'll inform you guys of the results after I get a new battery, so if anyone else has the same problem we can help them too

+1 on all above comments. It does appear battery/ hardware issue. Lets hope a new battery fixes it.
Andrometer will only confirm if charging level is reached. Also you can use it to check if at certain voltage this occures. It gives false positive on good health battery.So thats not a thorough indicator.
Guitar is way cooler btw :thumbup:

I searched for andrometer and all I got was an app to measure distance using GPS :s
So I got battery spy today and these are the results so far (See image).
My voltage is usually around 3900mV and 4300mV, usually at 4192mV, can anyone say if these values are normal??

Appears normal. Battery appears charged. app is called androsensor, mixed them up.
Do you get weird artifacts prior to fallout? Like screen flickering, lines and such?
Am so interested in cracking this nut.
You could check emmc brickbug app. You will have bug as all notes, but it also does a sector check. Like if part of emmc is corrupted. Am not expecting this to be case as clearly its battery related. Just want to be sure.
Sent from my GT-N7000 using Tapatalk 2
No flickering or anything, it's just like if I suddenly removed the battery.
Got new results from emmc check and I downloaded andrometer
Thank you so much for your help!
Cool.
I have a hunch its not battery, cause unstable battery usually(not 100% sure about symptoms) has those flickering issues.
Its not emmc, test passed yes!
you had it on different roms. With clean installs and different modems, kernels, etc. No common denominator romwise. maybe app or hardware.
Then its interesting to keep both cpu temp and battery temp in check. See if there are spikes prior to fallout. cpu temp I am not sure. you can try cooltool, disable gauges and setup cpu utilization, frequency, ram size, battery % and temperature.
watch those values for abnormalities when it occurs.
Also check the logs for errors/warnings (elixer2 has a good one)
But I am at a point of really guessing. I have a feeling its hardware but am hoping now for rogue app or battery still.
maybe someone else has some ideas.

Hey guys! My new battery just arrived and I just plugged it into my note and it is back to normal!
It's an official galaxy note replacement battery, 2600mah (100 more then the original, not much of a difference I know) and it was relatively cheap, 15 euros and I even had it delivered to my house!
I want to thank you guys for all your help and advices!
Thank you all from the heart! You contributed to making me a lot happier today!!
Best wishes for all of you, (dare I call you) my friends!
Thank you!

I had this same issue.. Mine was bought last year.. Just around 2 weeks ago i want to root and put a custom Rom...
I root using cf-root + philz kernel.. Then i flash rocketrom 4.1.2... V3 i think.. Then this issue came.... It 's does have flickering issue before it' s going off.. This all thing doesn't happen while on charge... I'm still not try using others battery..... I also have flash others custom Rom.. Like Ultimate, fusion.... And lastly i unroot it using stock fw at sammobile.. Still it's happen
Try changing the battery, that fixed my note right up!
Is the symptoms are the same as mine its not software related, order a new battery, and if you want you can root and flash the rom that you want so when it arrives your note is ready to go!
Tip: root the note and get battery calibration from the play store, it's free, you will need it to recalibrate your new battery so you get real values displayed and to avoid excessive battery drain.

I'm facing the same problem and its getting frustrating. I'm currently using Asylum ROM 20130303 build and latest Gapps for android 4.2. did a full wipe. tried checking my battery stats and its normal. did a recovery, flashed again but still problem. my gnote just shutdown and cant turn back on unless i plug the charger. any help?
may be you first need to try with an alternate battery first.. or go back to a stock rom and test.. most prominent symptom is using the camera with flash shuts down the phone immediately
i purchased a new battery and now its running fine
The phone is flawed and shuts off on it's own under various conditions, all hardware related. I am not able to post externally due to not having enough posts yet. However, I have had the same issue on 3 Galaxy Note 2's from Verizon. I made a video that shows exactly what is going on and posted it on the following website...
wwwDOTgalaxynote2shutsoffDOTcom
You will have to paste that link in to a new browser and replace the DOTs accordingly to get to it, but once you see the video, you will be enlightened. Be sure to read the details I provided on that site as well. They go in to detail about the problems that I have had and the lack of proper support that Samsung is willing to provide.
Same issue

I seem to have the same issue
1. Battery drains rather bad
2. Screen flickering
3. Auto shutdowm
Used the battery in my wifes n7000 , however no issues at all
Only seem to happen on my phone.
I flashed it to stock std 4.1.2 , however problem still persist. auto shutdown few times a day
Gets worse when i use an external SD
I've been experiencing very bad battery life lately. Currently using PAC, I could lose 10% of battery in under 20 minutes of normal web browsing with the brightness set all the way to low. I'm underclocked and undervolted, battery health is good. I don't really know what's causing my media server thing to use so much battery but it's definitely chewing up more juice than normal. How am I supposed to fix this?
Stop media scanning.
On the Store there is an app called Rescan Media Root.
Media server drain ia usually caused by the sd scanning proccess, sometimes a bad file can cause it to go nuts and keeps the proccess alive, thus killing your battery.
Give it a go.

I will also try this, my phone is only two days old and the battery life on this device is absolutely horrible compared to my Samsung Galaxy Note 2, I will check back with you folks and let you know the results
It is horrible compared to a Note 2, even if you didn't have that bug.
Plus, CM, AOSP, and PAC, all of them don't have that great of a battery life compared to stock.
Say you can get a solid 5+ hours out of a stock rom with few tweaks, whereas on those buolds mentioned you could get 4h, with not so great idling times.

Obviously horrible compared to a note 2 since note 2 has a bigger battery and lower resolution screen?

I'm trying it our now, report back in a day or so. This phone is bound to have worse battery life than the Note 2, it has 2 more cores, 2x more pixels, LCD screen, smaller battery, if you want great battery life go back to the Note or get a battery case. I didn't know that stock gives me more battery, maybe I should go back :/

Sony stock is very good rom to me. I will go to custom rom only if sony discontinued the updates, or sony makes the rom while drunk ( too much bugs, unstable... )
And, don't undervolt too much, -100mV is ok,
there's some test out there (not APQ8064), when undervolt too much, the processor will messed up the calculation, and re-calculate the process, wasting more battery and time. [this is applied to my old xperia arc]
If on Intel X86, I never get any issues/drawbacks from undervolting.
Sorry if I'm wrong, and sorry for my bad english.

i never said i had a custom rom, i went to install it, and it said i had to be rooted, and I'm not rooting my phone yet, thats why I asked if something similar was available for non rooted users.
Of course I'm not saying it's gonna get magically better but you should really give it more of a chance than two days a couple full charge cycles will help some,plus being new your prob setting up alot etc

thats definitely true, I know these batteries aren't supposed to have "memory" but should I do the full charge and drain with them?
I guess I'm under the assumption of it being newer and better technology then my Galaxy Note 2 I was coming from, I was expecting it to be right off the bat better.
thanks

Diff threads I read say it's no good to let it drain down to low, I usually charge around 20,30 percent I do about once a month let drain completely

Bad battery? So this type not worthed to buy?
Hey, the "rescan media server" app fixes the battery drain temporarily. How do I find out and delete the file that is causing my media scanner to keep running? I switched over to another ROM a few hours ago and media scanner is still taking a big chunk of my battery until I kill it. Do I need to reformat my card? Run anti virus?
Try this app. It is an android issue not an Sony issues. The mediaserver running all the time. This app will help. https://play.google.com/store/apps/details?id=com.addz.mediascannerroot

Crazy undervolt. I thought my -200 was about the max you could achieve.
My battery life is pretty terrible. Running stock, power saver, and Snapdragon battery guru. I have to charge the phone 2-3 times a day. I use in moderately to light through the day. At night, it will drain almost completely while I'm asleep. I had a Nexus 4 before and battery life was way better than this, same location, same apps, etc. I don't feel like I should need to turn data and wi-fi off to get more than 6 hours of virtually idle phone life from this device. Is this typical?
I find the phone is hot a lot too, when I am not even using it.
Please try to find out what causes this drain with the following app and post results after 1 unloading cycle

I downloaded it. Shut phone off and letting it charge, then going to see how fast it drains. To boot, its been on the charger for 2 hours and it has gone from 9% to 62%. Something must be wrong.
With stock my phone battery life sucked as well.that's why I rooted it and running a sense 5 Rom.. and it's so smooth I have my kernel UC to less than one gig speed and it still move fast without the overheat

Definitely not typical...
I'm fully stock and not rooted. If I dont touch my phone it can last over 24 hours with data on (noticed this one weekend when I was too busy to play with the phone).
I use the Battery Widget Reborn app and it says a "Fully charged battery usually lasts: 18 hours 8 minutes" for me.
Sounds like theres definitely some kind of app in the background thats draining your battery and making your phone hot.
This is pretty typical battery life for me with data always switched on on a rooted stock 4.2.2 rom and was also pretty much identical on an unrooted stock 4.1.2 rom.
The main thing that saves me a ton of battery life is disabling apps that I don't use. By far and away the Facebook app is a massive culprit for killing battery life.
I'm very interested to see the gsam results when you post them.

Well it's a definite improvement over the sort of battery life you were describing before. There are always ways of improving battery life but as has been said many times before it's all a case of where and how you use your phone that will be the main factor.

Install this program and see what is causing the wakelock...
Also is always good to use greenify to hibernate applications.
PS: Both applications require root.
Best Regards.
thanks but that got me no where it still does the same thing
my charger makes a strange noise like a buzz
maybe its the charger or the battery it self
The charger always make scary sounds ...
The same cautious if phone is off?
still no solution for the problem, its strange the battery that he consumes over night
Well, probably depends also how old your mobile is... I mean, after 4 years the battery can have lost capacity. Mine also needs around that over night, with Wifi and all Syncs and pushes activated. But theres nothing to do in my case i reinstalled firmware several times, its just gets old. Dunno but i could imagine you have the same "problem"...
What rom are you using?
You should try to flash stock rom.
Find them here lg-phone-firmware.com
we need battery logs..
I see a lot of people complaining about battery life, myself included. I have tried just about every ROM there is and used all the battery saving apps and I think I've found a winning combination that will leave you with a fast phone and good screen on/off battery life. My stats so far today are 8 hours off the charger with 1 hr 30 mins SOT and still 80% battery left and that's shifting between my work WiFi which has many access points and causes WLAN_RX wakelocks and the crappy signal around this area.
I use the phone for general stuff like browsing the web, playing the odd 2D game whilst bored and push notifications from various social networking apps and I have been addicted to achieving 7+ hours of SOT over 2 days since I owned a Galaxy S1 many years ago. Instead of writing a crazy guide I'll just keep this thread simple and post my current configuration that is giving me good battery life:
- BOE2 bootloader, modem and ROM (I'm using Nameless ROM v2 for 910G)
- Roughly 25% brightness, all sync on, location @ GPS only (High Accuracy only when using Maps)
- Followed THIS GUIDE very closely which gives amazing deep sleep and still get notifications with the Push Notification Fixer app
- Uninstalled Facebook and Messenger and use Tinfoil with Pushbullet and the RSS Feed and set to open Tinfoil when I get a notification: Here's how to do that
- Discharge fully to 0% and then turn on again to make sure fully dead, then charge to 100% to calibrate battery
Wallah! You should get good battery life now provided you use the phone for the same things I do. It's that easy!
You need to be rooted for most of that thread don't you? I need my banking app from time to time so I can't root. Gutted!
Joe
Thank you for taking the time to write this up, but you should mention in the thread title that you need to be rooted. Thanks anyways though. I'm not the type to root. If Samsung can't deliver a good product for the $800 device they made, the device should be returned (which will be my case if the 5.1.1 update doesn't come in July or it doesn't fix the issues I'm having with this device).

Fully discharging a Li-Ion battery is not healthy for the long term life of the battery.
When will the myth of "re-calibrating" a battery finally die?!?

Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The shorter the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine. There is no memory and the battery does not need periodic full discharge cycles to prolong life.

Thanks for the guide, and I'm not sure why anyone on XDA would not be rooted tbf

Smartphone batteries haven't needed to be calibrated in years. The only time you ever had to "calibrate" your battery was when your phone would sit at either 5% or 1% for hours before dying.
Even then you were calibrating your phones interpretation of the battery voltage levels, not the battery itself. Unless I'm very much mistaken battery charging is handled by integrated hardware, not software.
As a software bug overcharging a Li-Po is dangerous and completely avoidable

Because banking apps won't work on rooted devices.

Because root trips Knox which means in my workplace I can't use the phone for work proposes.

Most of the software needed on those guide required exposed.. My question is does amplify, greenify boost, and powernap works on touchwiz lollipop? Also does the current xposed works stably for now?
I have no battery issues. Got 2 x 4500mah from chima as well.

really??????
I see no need to root - does this mean I'm not allowed in here?

Lol
My Note 4 version can't even get full root, so I guess I'm not allowed either.

Huh? Never had a problem running official apps from two different banks.
I'm finding TW to be slightly better on battery under my circumstances - which consist of terrible signal fluctuation and rx_wlan wakelocks due to so many wireless arrays at work - however I will probably go back to CM12.1 soon or wait for Android M developer preview to be ported to Note 4 (fingers crossed) as I just love how stock and minimalistic everything is on stock droid CM and AOSP and it seems to be a lot snappier when combined with L-Speed mod.

My banking apps work a treat! Especially since you can just disable root and BAM it runs!

They fit with the original note cover. And they last a bit longer then original battery.
I bought 1 as well & I get about 3 more hours. .... with the same use as with the original battery !!!!! Definitely worth it, ,, even if its only 3 hours
